Then, as described later, when it is sensed that the camera body 111 is mounted on the stand 130 , control means composed of the CPU 154 and LCD driver 155 controls the brightness changing means. As a result, the direction of the field angle at the LCD 122 is changed to a setting value (direction) suitable for the electronic camera 110 mounted on the stand.

Then, specific image data whose frames are specified is read from the image recording medium 153 and undergoes an expansion process at the image processing unit 152 . The resulting data is stored in the temporary storage circuit 151 .
- the stand mounting sensing circuit 160 informs the CPU 154 of stand mounting information SA “absent.” Consequently, the CPU 154 informs the LCD driver 155 of brightness changing instruction SC “absent.” Therefore, the image based on the reproduce image data stored in the temporary storage circuit 151 is displayed on the LCD display section 22 at a standard brightness (of a suitably set value), for example, at [ ⁇ 1] (see FIG. 28A ). Thus, as shown in FIG. 30A , the displayed image can be seen well in the range of a field angle of ⁇ .

- the image based on the reproducing image data stored in the temporary storage circuit 151 is displayed on the LCD 122 at the brightness changed and set as described above, for example, at [+3] (see FIG. 28B ).
- the image can be seen well in the range of a field angle of ⁇ (equal to ⁇ ) at the setting value (direction) changed according to the position in which the camera body 11 is mounted on the stand 30 (with an inclination of, for example, about 10° to a horizontal plane).
- the setting value of the direction of the field angle can be adjusted and set by manually operating the operating section 138 .
- the brightness decrease button 138 a has only to be pressed a desired number of times.
- the brightness increase button 138 b has only to be pressed a desired number of times. Then, pressing the setting button 138 c determines the adjusted value.
- the latter value may be obtained by adding a specific correction value to the setting value for normal use. This makes it possible to automatically set and change the setting value for use with the camera mounted on the stand, just by carrying out the setting and changing operations for normal use.

Description
- The present application is a continuation application of U.S. application Ser. No. 10/238,387, filed Sep. 09, 2002 which is based upon and claims the benefit of priority from the prior Japanese Patent Applications No. 2001-275621, Sep. 11, 2001; No. 2001-275623, Sep. 11, 2001; No. 2001-293943, Sep. 26, 2001; No. 2001-295122, Sep. 26, 2001; No. 2001-305793, Oct. 1, 2001; and No. 2001-308927, Oct. 4, 2001, the entire contents of all of which are incorporated herein by reference.
- This invention relates to an electronic apparatus, such as an electronic camera, and an electronic apparatus stand on which the electronic apparatus can be mounted in a specific position, and to an electronic apparatus stand system including the electronic apparatus and electronic apparatus stand.
- One known electronic apparatus stand system is configured so as to enable an electronic apparatus, such as an electronic camera, to be mounted on a stand in a specific position in order to display the electronic apparatus as, for example, an interior set, in a room.
- For example, Jpn. Pat. Appln. KOKAI Publication No. 2001-69388 has disclosed an electronic camera system which enables an electronic camera to be mounted on a camera stand with a charger in such a manner that the front of the camera faces to the front of the stand. The electronic camera system is capable of charging the secondary battery of the electronic camera mounted, setting the correct date in the electronic camera, causing the strobe to emit light to enhance the wake-up function, turning on the backup light for indicating the charging time, and others.
- Jpn. Pat. Appln. KOKAI Publication No. 2000-333046 has disclosed an electronic camera system which enables an electronic camera to be mounted on a camera stand with a charger in such a manner that the back of the camera faces to the front of the stand. The electronic camera system is capable of charging the secondary battery of the electronic camera mounted, causing the liquid-crystal display section at the back of the camera to display images (or make a slide show) during or after charging, and others.
- As described in the above publications, in a conventional ordinary electronic camera system, the electronic camera is mounted on the camera stand in such a manner that the camera faces either forward or backward. Depending on the direction in which the electronic camera is mounted, a limitation is imposed on the functions the electronic camera can achieve.
- For example, in a configuration with the front of the camera mounted so as to face to the front of the stand as in the electronic camera system disclosed in Jpn. Pat. Appln. KOKAI Publication No. 2001-69388, no consideration has been given to the way of, for example, viewing images while displaying the images on the liquid-crystal monitor at the back of the camera, with the electronic camera mounted on the stand.
- Furthermore, in a configuration with the back of the camera mounted so as to face to the front of the stand as in the electronic camera disclosed in Jpn. Pat. Appln. KOKAI Publication No. 2000-333046, no consideration has been given to the way of, for example, taking pictures with the electronic camera mounted on the stand.
- That is, in the prior art, making good use of various functions the electronic camera intrinsically has, including photographing, reproducing, image transferring, and printing functions, has been considered to be impossible in a state where the electronic camera is mounted on the camera stand.
- In addition, with the electronic camera mounted on the camera stand, this imposes restrictions on the operation of selecting and setting the operation mode (such as photograph mode or reproduce mode) to carry out the functions. That is, depending on the direction in which the electronic camera is mounted on the camera stand, controls (including buttons) provided on the electronic camera are arranged in a place difficult to operate, or the liquid-crystal monitor for displaying the selected or set operation mode is covered by the wall of the stand. This caused the following problems: the operation mode was liable to be selected or set erroneously, and the operation mode displayed on the liquid-crystal monitor was difficult to check visually.
- It is, accordingly, an object of the present invention to overcome the above problems by providing an electronic apparatus, such as an electronic camera, a stand, and an electronic apparatus stand system which have the advantages described below:
-
- a. The direction in which an electronic apparatus, such as an electronic camera, is mounted on a stand can be changed and therefore it is possible to make good use of the electronic apparatus.
- b. A suitable operation mode is selected and set according to the direction in which an electronic apparatus, such as an electronic camera, is mounted on a stand.
- c. Even when an electronic apparatus, such as an electronic camera, is mounted on a stand either in a first direction in which the front of the electronic apparatus faces to the front of the stand or in a second direction in which the back of the electronic apparatus faces to the front of the stand, electric power is supplied to the electronic apparatus properly.
- d. Even when an electronic apparatus, such as an electronic camera, is mounted in a lengthwise position on a stand, the image is displayed in an upright position by display means and therefore is easy to see.
- e. Even when an electronic apparatus, such as an electronic camera, is mounted on a stand in an upward- or downward-inclined manner, the image displayed by the liquid-crystal display is easy to see.
- f. There is no photographing limit due to the consumption of the battery and therefore photography can be continued stably for a long time.
- g. The monitoring function can be achieved with the photographing operation unnoticed.
- h. The camera can be examined automatically without any problem while the camera is in use.
- i. Defective pixels can be sensed accurately without being affected by the temperature.

The same holds true for theelectric contacts electric contact electric contact 17 provided on the outermost side of the contact group a is a contact used to determine the direction in which the electronic camera is mounted on thestand 18. Theelectric contact 17 is provided only on the a-contact group side, not on the b-contact group side. -
FIG. 3 is a front view showing a state where the electronic camera according to the first embodiment of the invention is mounted on the stand in such a manner that the front of the camera faces to the front of the stand.FIG. 4A toFIG. 4C show a state where the electronic camera according to the first embodiment of the invention is mounted on the stand in such a manner that the back of the camera faces to the front of the stand.FIG. 4A is a left side view. FIG, 4B is a front view.FIG. 4C is a sectional view taken along line C-C ofFIG. 4B . - As shown in
FIG. 3 , theelectronic camera 1 has such an exterior as can be mounted on thestand 18 with the left side face of thecamera 1 down in a state where the slidinglid 5 is open. As shown inFIG. 3 , thestand 18 has such an exterior as enables theelectronic camera 1 to be mounted either in a first direction in which the front of the camera faces to the front of the stand or in a second direction in which the back of the camera faces to the front of the stand as shown inFIG. 4A andFIG. 4B . Thestand 18 has an ACpower supply plug 19 outside of it. Thestand 18 has power supplying means (not shown) for supplying power to the mountedelectronic camera 1 in it. - In the center of the camera mounting section of the
stand 18, aconnection 20 for supplying power to theelectronic camera 1 and performing data transmission and reception to and from theelectronic camera 1 is provided in such a manner that the connection faces theconnection 4 of theelectronic camera 1. - As described above, the connection is so formed that, even when the camera is mounted on the
stand 18 in such a manner that the front of the camera faces to either the front or the back of the stand, the relative positions of theconnection 4 of theelectronic camera 1 and theconnection 20 of the stand remain unchanged. -
FIG. 5 is an enlarged plan view showing a configuration of the connection on the stand side shown inFIG. 3 andFIG. 4A toFIG. 4C .FIG. 5 shows the connection viewed from the mounting direction (inserting direction or installing direction) of the electronic camera as shown by the arrow V inFIG. 4B . - As shown in
FIG. 5 , theconnection 20 has electric contacts 21 (21 a, 21 b), 22 (22 a, 22 b), 23 (23 a, 23 b), 24 (24 a, 24 b), 25 (25 a, 25 b), 26 (26 a, 26 b), and 27 corresponding to theelectric contacts connection 4 of theelectronic camera 1. Theseelectric contacts 21 to 27 are formed in the same manner as theelectric contacts 11 to 17 of theconnection 4. - Specifically, the individual
electric contacts 21 to 27 are divided into an a-contact group and a b-contact group and arranged in such a manner that these groups are provided so as to face each other with a 180° difference in position between them on a straight line P-Q crossing radially a plurality of concentric circles (dotted lines inFIG. 5 ) arranged at regular intervals with point O in the center. As shown in the figure, each of theelectric contacts 21 to 27 has a specific length and is shaped like an arc. There is a continuity between theelectric contacts electronic camera 1. The same holds true for theelectric contacts electric contact electric contact 27 provided on the outermost side of the contact group a is a contact used to determine the direction in which theelectronic camera 1 is mounted on thestand 18. Theelectric contact 27 is provided only on the a-contact group side, not on the b-contact group side. - The a-contact group and b-contact group of the
connection 4 in theelectronic camera 1 and the a-contact group and b-contact group of theconnection 20 in thestand 18 are so formed that, when theconnection 4 and theconnection 20 are rotated relatively through 180° with point O in the center, the corresponding contact groups overlap with one another. - Accordingly, when the
electronic camera 1 is mounted on thestand 18 in the first direction so that the front of the camera may face to the front of the stand, one a-contact group comes into contact with the other a-contact group and establishes a continuity between them, that is, theelectric contacts connection 4 make contact with theelectric contacts connection 20 and establish a continuity between them. At the same time, one b-contact group comes into contact with the other b-contact group and establishes a continuity between them, that is, theelectric contacts connection 4 make contact with theelectric contacts connection 20 and establish a continuity between them. - When the
electronic camera 1 is mounted on thestand 18 in the second direction so that the back of the camera may face to the front of the stand, the a-contact group of theconnection 4, or theelectric contacts connection 20, or theelectric contacts connection 4, or theelectric contacts connection 20, or theelectric contacts - In the latter case, the
electric contact 17 of theconnection 4 in theelectronic camera 1 does not make contact with theelectric contact 27 of theconnection 20 in thestand 18. Thus, by sensing the contact/uncontact (or continuity/discontinuity) between theelectric contact 17 and theelectric contact 27, thecamera 1 can determine automatically whether the front of the camera faces to either the front of the stand or the back of the stand. - The
stand 18 has alight guide 29 as shown inFIG. 3 ,FIG. 4B , andFIG. 4C . When the camera is mounted in the second direction so that the back of the camera may face to the front of the stand, thelight guide 29 directs a remote control signal sent from the stand front side (or camera back side) to the remote control signal light-receivingwindow 7. Therefore, regardless of whether the front of the camera faces the front of the stand or the back of the stand, the remote control signal can still be received. - In addition to the parts described above, the
stand 18 also includes a video signal output terminal and a USB terminal. -
FIG. 6 is a block diagram showing a primary configuration of an electronic camera system including theelectronic camera 1 and stand 18. In the upper part ofFIG. 6 , a system configuration of theelectronic camera 1 is shown. In the lower part ofFIG. 6 , a system configuration of thestand 18 is shown. - First, the system configuration of the
electronic camera 1 will be explained. A photographinglens section 30 is a photographing optical system which forms an image of a subject on a photographingelement 31. - The photographing
element 31 converts the formed subject image photoelectrically and outputs an electric signal (analog signal) representing the image. - A photographing
section 32 is configured so as to enable CDS (Correlated Double Sampling) and AGC (Automatic Gain Control). The photographingsection 32 removes reset noise from the electric signal (analog signal) outputted from the photographingelement 31 or adjusts its signal level. - An A/
D converter circuit 33 converts the output signal (analog signal) from the photographingsection 32 into a digital signal (digital data). - Not only the A/
D converter circuit 33 but also aDRAM 34, animage processing section 35, aflash memory 36, avideo driver 37, a USB (Universal Serial Bus) I/F 38, anLCD driver 39, aROM 40, aCPU 41 and others are all connected to abus line 42. Through thebus line 42, they exchange data with each other. - The
DRAM 34 is used as a buffer memory that temporarily stores the image data output from the A/D converter circuit 33, the image data processed by theCPU 41, and the like. TheDRAM 34 is also used as a work memory for various processes. - The
image processing section 35 carries out a γ correction process (γ for recording), a color process (white balance), and other processes on the image data to correct the brightness, saturation, and hue of an image and the like. Theimage processing section 35 further carries out an image data compression process and an image data expansion process or the like. The compression process and expansion process are performed by, for example, JPEG (Joint Photographic Experts Group). - The
flash memory 36 is a rewritable memory in which image data is recorded (stored). - The
video driver 37 is a circuit that converts image data into a video signal for a display unit, such as a TV (television) connected to the videosignal output terminal 43. - The USB-I/
F 38 is an interface for exchanging data with an external unit connected to theUSB terminal 44, such as a PC (personal computer) or a printer. - The
LCD driver 39 drives and controls the LCD (liquid-crystal display) 3 to cause theLCD 3 to display image information or the like on the basis of the image data. - The
ROM 40 is a memory in which an operation program for controlling theelectronic camera 1 is stored. - The CPU (central processing unit) 41 control the operation of the entire camera according to the camera program stored in the
ROM 40, using theDRAM 34 as a work area. For example, theCPU 41 carries out a process according to the user's instruction accepted via aninput section 45, a process according to the remote control signal inputted via a remote control signal light-receivingsection 46, or the like. - Furthermore, the CPU determines the direction in which the
electronic camera 1 is mounted, from the coupling relationship of theconnection 20 with theconnection 4. On the basis of the determination, the CPU not only selects and sets a suitable operation mode according to the mounting direction but also carries out the process of inhibiting an unsuitable operation mode from being set. - The
input section 45 includes therelease button 2 and various other buttons, including a power switch (not shown). The input section accepts various instructions from the user via the various buttons and switches and informs theCPU 41 of the accepted instructions. - The remote control signal light-receiving
section 46 receives a remote control signal sent from a remote control unit (not shown) and supplies its output signal to theCPU 41. - The
connection 4, as described above, is for supplying power from thestand 18 and transmitting and receiving data to and from thestand 18. Theelectric contact 13 in theconnection 4 is connected to the output terminal of thevideo driver 37 and outputs a video drive signal. The electric contacts 14, 15 are connected to the USB-I/F 38 and transmit and receive USB signals. Theelectric contact 16 is connected to theCPU 41 and transmits information on whether theelectronic camera 1 is mounted on thestand 18. Theelectric contact 17 is also connected to theCPU 41 and transmits information on the direction in which theelectronic camera 1 is mounted on thestand 18. Theelectric contact 11 is also connected to theCPU 41 and transmits an instruction signal to provide ON/OFF of the power supply of theelectronic camera 1. Theelectric contact 12 is connected to achangeover circuit 48 and supplies power from thestand 18. - Although not shown, the
electric contacts electric contact 16 is connected to GND, it is sensed whether theelectronic camera 1 is mounted on thestand 18. - In the first embodiment, when the
electric contact 16 is connected to GND, it is determined that theelectronic camera 1 is mounted on thestand 18. When theelectric contact 17 is connected to GND, it is determined that the front of the camera faces to the front of the stand. - A
battery 47, which is either a primary battery or a secondary battery, supplies electric power to theelectronic camera 1. - The
changeover circuit 48 switches the supply destination of the power supply obtained via theconnection 4 to either a chargingcircuit 49 or apower supply circuit 50 under the control of theCPU 41. For example, when thebattery 47 is a primary battery, thechangeover circuit 48 switches the supply destination of the power supply to thepower supply circuit 50. - The charging
circuit 49 includes a battery remainingpower sensing section 49′ for sensing the amount of remaining power of the battery 47 (or the amount of remaining power of the power supply). When the battery remainingpower sensing section 49′ senses that the amount of remaining power of thesecondary battery 47 is insufficient, the chargingcircuit 49 charges thebattery 47. - The
power supply circuit 50 controls the power supply supplied from thebattery 47 or thechangeover circuit 48 under the control of theCPU 41, thereby supplying electric power to each section of theelectronic camera 1. - In the
electronic camera 1 with the above configuration, if thestand 18 has the ability to provide a sufficient power supply, thechangeover circuit 48 may be omitted and thestand 18 may supply power to both thesecondary battery 47 and thepower supply circuit 50. - Next, the system configuration of the
stand 18 will be explained. Theconnection 20 is for supplying power to theelectronic camera 1 and transmitting and receiving data to and from theelectronic camera 1. - The
electric contact 23 in theconnection 20, which is connected to a videosignal output terminal 51, is capable of outputting a video signal. The electric contacts 24, 25, which are connected to a USB terminal, are capable of transmitting and receiving USB signals. Theelectric contact 26, which is connected to GND, provides information on whether theelectronic camera 1 is mounted on thestand 18, by supplying the ground potential to theelectronic camera 1 side via theconnection 4. Theelectric contact 27, which is also connected to GND, provides information on the direction in which theelectronic camera 1 is mounted on thestand 18, by supplying the ground potential to theelectronic camera 1 side via theconnection 4. - The
electric contact 21 is connected to a stand switch (Power SW) 53. Thestand switch 53 is for giving an instruction to provide ON/OFF of the power supply of the mountedelectronic camera 1. Thus, an instruction to provide ON/OFF of the power supply by the ON/OFF operation on thestand switch 53 is transmitted via theelectric contact 21 to the electronic camera side. Theelectric contact 22 is connected to the output terminal of an AC/DC converter circuit 54. The AC/DC converter circuit 54 is a circuit that converts, for example, a 100V AC power supply input by an ACpower supply plug 19 into, for example, a 6V DC power supply. Therefore, the DC power supply converted by the AC/DC converter circuit 54 is supplied to the electronic camera side via theelectric contact 22. - The vide
signal output terminal 51 is for outputting a video signal to a display unit connected to the terminal, such as a TV. TheUSB terminal 52 is for exchanging a USB signal with an external unit connected to the terminal 52, such as aPC 55 or aprinter 56. - Next, the operation modes selected and set according to the mounting direction of the
electronic camera 1 and the operation modes inhibited from being set in the first embodiment will be explained. -
FIG. 7 shows an example of the relationship between the mounting directions of theelectronic camera 1 and the operation modes selected and set and the operation modes inhibited from being set. In the figure, the mark ◯ indicates an operation mode to be selected and set according to the mounting direction of theelectronic camera 1. The mark X indicates an operation mode to be inhibited from being set according to the mounting direction of theelectronic camera 1. The mark Δ indicates a mode to be selected and set according to an instruction from the user via thePC 55. As for the charging mode, it is set only when the power supply of theelectronic camera 1 is off, regardless of the direction in which theelectronic camera 1 is mounted. - As shown in
FIG. 7 , when it is determined that theelectronic camera 1 is mounted on thestand 8 in the first direction so that the front of the camera may face to the front of the stand, not only the charging mode (when the power supply is off) or the photographing mode (when the power supply is on) is selected and set, but also control is performed so that the reproducing mode and the printing mode are inhibited from being set. The reason is that there is no sense in displaying the reproduced image or the printing image instruction behind the back of the stand, as the user cannot see it. - If the
electronic camera 1 is mounted on thestand 18 in the first direction and the power supply of theelectronic camera 1 is on, when thePC 55 is connected to theUSB terminal 52 of thestand 18 and the user operates the input section (such as a keyboard) of thePC 55 to give a specific instruction to theelectronic camera 1, the operation mode is changed from the photographing mode to the PC communication mode and the processes corresponding to the instruction are carried out. - For example, the photographing process corresponding to a photograph instruction or the process corresponding to the instruction to transfer image data (or image file) recorded in the
flash memory 36 of theelectronic camera 1 is carried out. In this case, however, when the user's instruction specifies a process (such as a reproduction process or printing process) related to the operation mode marked with the symbol X, the process related to the operation mode is not carried out, because the operation mode is inhibited from being set. - As shown in
FIG. 7 , when theelectronic camera 1 is mounted on thestand 18 in the second direction so that the back of the camera may face to the front of the stand, not only is the charging mode (when the power supply is off) or the reproducing mode (when the power supply is on) selected and set according to the ON-OFF state of the power supply, but also control is performed so that the photographing mode is inhibited from being set. The reason why the photographing mode is inhibited is that, if photographing were effected with the photographinglens section 30 and the like facing the back of the stand, only a disappointing result would be obtained. - If the
electronic camera 1 is mounted on thestand 18 in the second direction and the power supply of theelectronic camera 1 is on, when thePC 55 is connected to theUSB terminal 52 of thestand 18 and the user operates the input section of thePC 55 to give a specific instruction to theelectronic camera 1, the operation mode is changed from the reproduction mode to the PC communication mode and the process corresponding to the instruction is carried out. - For example, the reproducing process corresponding to a reproduce instruction or the process corresponding to an instruction to transfer the image data recorded in the
flash memory 36 of theelectronic camera 1 is carried out. When the instruction is a print instruction, the operation mode is changed to the printing mode and the processes corresponding to the instruction are carried out. In this case, too, when the user's instruction specifies a process (in this case, the photographing process) related to the operation mode marked with the symbol X, the process related to the operation mode is not carried out, because the operation mode is inhibited from being set. - Next, an example of the operation of the first embodiment will be explained. With both the power supply switch of the
electronic camera 1 and thestand switch 53 being off, when theelectronic camera 1 is mounted on thestand 18 so that the front of the camera faces either the front or the back of the stand, theelectric contacts 11 to 16 of theelectronic camera 1 come into contact with theelectric contacts 21 to 26 of thestand 18, respectively. As a result of theelectric contact 16 making contact with the electric contact 26 (GND), it is sensed that theelectronic camera 1 has been mounted on thestand 18. At this time, the direction in which theelectronic camera 1 is mounted is determined, depending on whether theelectric contact 17 has made contact with theelectric contact 27. Then, according to the determined direction in which theelectronic camera 1 has been mounted, not only is a suitable operation mode selected and set, but also the improper operation modes are inhibited from being set. At this point in time, however, because the power supply of theelectronic camera 1 is off, the operation mode to be selected and set is the charging mode, regardless of the mounting direction of theelectronic camera 1. - When it is determined that the
electric contacts electric contacts electronic camera 1 is performed each time theelectronic camera 1 is mounted on thestand 18. - It is now assumed that the
electronic camera 1 is mounted on thestand 18. Now, thestand 18 supplies power to theelectronic camera 1 via theelectric contacts electronic camera 1 is the charging mode. Therefore, thechangeover circuit 48 switches the power supply destination to the chargingcircuit 49, which starts to charge thebattery 47, a secondary battery. When the amount of the remaining power of thebattery 47, a secondary battery, indicates Full, or when thebattery 47 is a primary battery, the charging operation is not performed. - Here, when the
stand switch 53 is turned on to turn on the power supply of theelectronic camera 1, theCPU 41 is informed via theelectric contacts changeover circuit 48 switches the power supply destination to thepower supply circuit 50. Thus, electric power is supplied to each section of theelectronic camera 1 via thepower supply circuit 50. As described above, when the power supply of theelectronic camera 1 is turned on, the operation mode is changed from the charging mode to a specific operation mode according to the determined mounting direction of theelectronic camera 1. - For example, when it is determined that the camera is mounted so that the front of the camera faces the front of the stand, the operation mode is changed from the charging mode to the photographing mode. In a state where the operation mode has been changed to the photographing mode, when a photograph instruction is received from, for example, a remote control unit (not shown), the photographing process corresponding to the instruction is carried out.
- Furthermore, in a state where the
PC 55 is connected to theUSB terminal 52 of thestand 18, when the user operates the input section of thePC 55 to give a specific instruction to theelectronic camera 1, the operation mode is changed from the photographing mode to the PC communication mode and the process corresponding to the instruction is carried out. For example, the photographing process corresponding to the photograph instruction, the process corresponding to the image data transfer instruction, or the like is carried out. At this time, however, since the reproduction mode and the printing mode are inhibited from being set, neither the reproducing process nor the printing process are carried out, even if the user gives a reproduce instruction or a print instruction. Here, to execute the reproducing process or printing process with theelectronic camera 1 mounted on thestand 18, the user has only to change the mounting direction of theelectronic camera 1. - If the power supply of the
electronic camera 1 is turned on, when it is determined that the back of the camera faces the front of the stand, the operation mode is changed from the charging mode to the reproducing mode. In a state where the operation mode has been changed to the reproducing mode, a reproduce instruction is received from, for example, the remote control unit (not shown), the reproducing process is carried out according to the instruction. In this case, however, the optical signal from the remote control unit is inputted via thelight guide 29 of thestand 18. - Furthermore, in a state where the
PC 55 is connected to theUSB terminal 52 of thestand 18, when the user operates the input section of thePC 55 to give a specific instruction to theelectronic camera 1, the operation mode is changed from the reproducing mode to the PC communication mode and the process corresponding to the instruction is carried out. For example, the reproducing process corresponding to a reproduce instruction, the process corresponding to an image data transfer instruction, or the like is carried out. When the instruction is a print instruction, the operation mode is changed to the printing mode and the printing process corresponding to the print instruction is carried out. At this time, however, since the photographing mode is inhibited from being set, the photographing process is not carried out, even if the user gives a photograph instruction. Here, to execute a photographing process with theelectronic camera 1 mounted on thestand 18, the user has only to change the mounting direction of theelectronic camera 1. - As described above, with the first embodiment, even when the
electronic camera 1 is mounted on thestand 18 in such a manner that the front of the camera faces to the front or the back of the stand, it is possible to supply power from thestand 18 to theelectronic camera 1 and achieve data transmission and reception between theelectronic camera 1 and thestand 18. Therefore, the user can make good use of theelectronic camera 1 mounted on thestand 18. - Furthermore, according to the mounting direction of the
electronic camera 1, a suitable operation mode for the mounting direction is selected and set automatically. Thus, there is no need for the user to operate the input specifysection 45 of theelectronic camera 1 manually and select and set the operation mode as in the prior art. There is no possibility that limited operations will cause the operation mode to be selected or set erroneously. Since the setting of the operation modes unsuitable for the mounting direction is automatically inhibited according to the mounting direction of theelectronic camera 1, neither a meaningless process nor an unwanted process is carried out. - In addition, the following modification of the first embodiment can be considered. For example, the way the
electronic camera 1 is connected to thestand 18 is not limited to the use of theconnection 4 shown inFIG. 2 and theconnection 20 shown inFIG. 5 . Any connection form may be used, provided that the connection between the front of the camera and the front of the stand is possible even when theelectronic camera 1 is mounted on thestand 18 so that the front of the camera faces to either the front or the back of the stand. For instance, in theconnection 4 shown inFIG. 2 , theelectric contacts connection 20 shown inFIG. 5 , theelectric contacts - While in the first embodiment, means for sensing the direction in which the
electronic camera 1 is mounted is configured so as to use the contact/noncontact (or continuity/discontinuity) between theelectric contacts electronic camera 1 and further a projecting part corresponding to the mounting direction sensing switch may be provided on thestand 18. With this configuration, only when the camera is mounted in such a manner that the front of the camera faces the front or the back of the stand, the projecting part pushes back the mounting direction sensing switch to turn on the switch. Alternatively, an optical sensor may be provided on theelectronic camera 1, and further, a light cutting-off projecting part or the like may be disposed on thestand 18. With this configuration, only when the camera is mounted in such a manner that the front of the camera faces the front or the back of the stand, the projecting part or the like cuts off the light to turn on the mounting direction sensing switch. Furthermore, if an AE (Automatic Exposure) sensor and a WB (White Balance) sensor or the like are provided at the front of the camera, when the camera is mounted so that the front of the camera faces the back of the stand, those sensors are covered with the back of the stand and therefore the outputs of the sensors become low. -
FIG. 8 is a block diagram showing a primary configuration of an electronic camera system including anelectronic camera 1 and astand 18 according to a second embodiment of the present invention. To simplify an explanation, the same parts as those inFIG. 6 are indicated by the same reference numerals and an explanation of the parts is omitted. - As shown in
FIG. 8 , anelectronic camera 57 according to the second embodiment further comprises a lens cover (or a lens barrier) 58 for protecting the photographinglens section 30 and the like and a lens cover switch (SW) 59. The lens cover 58 of the second embodiment, which is a manually-operated cover, can be opened and closed freely by the user. Thelens cover switch 59 is a switch that performs on/off operations in such a manner that it interlocks with the opening and closing of thelens cover 58. - The CPU 64 carries out almost the same processes as those carried out by the
CPU 41 shown inFIG. 6 . The CPU 64 differs from theCPU 41 in that the former carries out the processes taking into account the open or closed state of thelens cover 58 when a suitable operation mode is selected and set according to the mounting direction of theelectronic camera 57, and unsuitable operation modes are inhibited from being set. -
FIG. 9 shows an example of the relationship between the mounting direction of theelectronic camera 1, the open or closed state of thelens cover 58, the operation modes to be selected and set, and the operation modes to be inhibited from being set. The marks ◯, X, Δ shown in the figure have the same meanings as those inFIG. 7 . - In
FIG. 9 , when thelens cover 58 is in the open state (I), (III), the operation modes to be selected and set are the same as the operation modes shown inFIG. 6 . With the lens cover in the closed state (II), (IV), when the power supply of the mountedelectronic camera 57 is off, the charging mode is selected and set, regardless of the mounting direction of theelectronic camera 57. - If the
electronic camera 57 is mounted on thestand 18 in the first direction so that the front of the camera faces the front of the stand and the lens over 58 is in the closed state (II), when the power supply of theelectronic camera 57 is turned on, not only is the PC communication mode selected and set, but also the reproduction mode, printing mode, and photographing mode are inhibited from being set. The reason why the photographing mode is inhibited from being set is that the photographing process cannot be carried out with thelens cover 58 in the closed state. - If the
electronic camera 57 is mounted on thestand 18 in the second direction so that the back of the camera faces the front of the stand and the lens over 58 is in the closed state (IV), when the power supply of theelectronic camera 57 is turned on, not only is the PC communication mode selected and set, but also the reproduction mode and photographing mode are inhibited from being set. In this case, however, when the user gives a print instruction via thePC 55, the operation mode is changed to the printing mode and the printing process corresponding to the print instruction is carried out. - Even if a manually operated
lens cover 58 is provided, as in theelectronic camera 57 of the second embodiment, a suitable operation mode according to the mounting direction of theelectronic camera 57 can be selected and set automatically and the setting of the unsuitable operation modes can be inhibited automatically. - In the second embodiment, the opening/closing of the
lens cover 58 in theelectronic camera 1 may be linked with the turning on and off of the power supply. -

FIG. 15 shows a state where amirror frame unit 8 is stuck forward out of the camera.FIG. 16 shows a state where the front of the stand faces in the direction of the arrow B. To simplify an explanation, the same component parts inFIG. 13 toFIG. 17 as those in the first embodiment (FIG. 1A toFIG. 7 ) are indicated by the same reference numerals and an explanation of the parts is omitted. - In the fourth embodiment, the supply of power from the stand to the electronic camera and data transmission and reception between the electronic camera and the stand are carried out by a non-contact transmission system and that the direction of the electronic camera mounted on the stand is sensed by a mounting direction sensing switch.
- As shown in
FIG. 13 andFIG. 14 , a power-receivingcoil 75 for receiving power from thestand 71 in a noncontacting manner is embedded in the center of the base of theelectronic camera 70 as shown by dotted lines. In addition, a power-supplyingcoil 81 for supplying power to theelectronic camera 70 in a non-contact manner is embedded as shown by dotted lines. - The power-receiving
coil 75 of theelectronic camera 70 and the power-supplyingcoil 81 of thestand 71 are arranged so that they face each other, whether the front or back of the camera faces the front of the stand as shown inFIG. 13 . - As shown in
FIG. 15 , in the vicinity of the power-receivingcoil 75 at the base of the camera, there are provided a light-emittingwindow 72 for sending the optical signal emitted from a light-emitting element, explained later, to thestand 71 side and a light-receivingwindow 73 for receiving the optical signal sent from thestand 71 and letting the signal enter a light-receiving element, explained later. In two positions symmetrical with each other at the base of the camera, a pair of engagingholes hole 74 a, there is provided a mountingdirection sensing switch 90 that turns on when a projecting part provided on thestand 71 side is inserted into the hole 74. In the inner part of the other engaginghole 74 b, such a mounting direction sensing switch is not provided. At the base of the camera, there are provided thesame battery compartment 61,tripod screw 62, and others as those ofFIG. 12 . - In the fourth embodiment, whether the camera is mounted with the front of the camera facing the front or the back of the stand is determined according to the output of the mounting
direction switch 90. Specifically, with theelectronic camera 70 mounted on thestand 71, when the mountingdirection sensing switch 90 is on, it is determined that the front of the camera faces to the front of the stand. When the mountingdirection sensing switch 90 is off, it is determined that the back of the camera faces to the front of the stand. - As shown in
FIG. 16 , in the vicinity of the part where the power-supplyingcoil 81 embedded in the camera mounting section (in the figure, the two-dots-dash line part corresponding to an imaginary line representing the base of the camera) 71 a formed in the upper part of thestand 71, there are provided light-receivingwindows electronic camera 70 and letting the signal enter a light-receiving element, explained later; light-emittingwindows part 78 inserted into either the engaginghole electronic camera 70 when theelectronic camera 70 is mounted on thestand 71, and others. - The light-receiving
windows light guide 79 shown by a dotted line. The light-emittingwindows light guide 80 shown similarly by a dotted line. - As shown in
FIG. 17 , thelight guide 79 is for directing an optical signal inputted through the light-receivingwindows element 82. Thelight guide 80 is for directing the optical signal emitted from the light-emittingelement 83 to the light-emittingwindows windows element 82, which then receives the signals. In addition, the optical signal emitted from a light-emittingelement 83 is directed by thelight guide 80 to the light-emittingwindows - Thus, when the
electronic camera 70 is mounted on the stand so that the front of the camera faces the front of the stand, the power-receivingcoil 75 of theelectronic camera 70 comes close to and faces the power-supplyingcoil 81 of thestand 71. Moreover, the light-emittingwindow 72 and light-receivingwindow 73 of theelectronic camera 70 face the light-receivingwindow 76 a and light-emittingwindow 77 a of thestand 71, respectively. At this time, the projectingpart 78 of thestand 71 is inserted into the engaginghole 74 a of theelectronic camera 1. - Furthermore, when the
electronic camera 70 is mounted on the stand so that the back of the camera faces the front of the stand, the power-receivingcoil 75 of theelectronic camera 70 comes close to and faces the power-supplyingcoil 81 of thestand 71. Moreover, the light-emittingwindow 72 and light-receivingwindow 73 of theelectronic camera 70 face the light-receivingwindow 76 a and light-emittingwindow 77 b of thestand 71, respectively. At this time, the projectingpart 78 of thestand 71 is inserted into the engaginghole 74 b of theelectronic camera 1. - With this configuration, when the
electronic camera 70 is mounted on thestand 71 so that the front of the camera faces either the front or the back of the stand, the mounting direction is determined from the output of the mountingdirection sensing switch 90. - It is therefore possible to supply power from the
stand 71 to theelectronic camera 70 and perform data transmission and reception between theelectronic camera 70 and stand 71. Whether the front of the camera faces the front or back of the stand. - In the fourth embodiment, a light guide may be provided for directing the remote control signal transmitted from the stand front side to the remote control signal light-receiving
window 7 when theelectronic camera 70 is mounted on thestand 71 with the back of the camera facing the front side of the stand. -
FIG. 18 is a block diagram showing a principal configuration of an electronic camera system including theelectronic camera 70 and stand 71 according to the fourth embodiment. InFIG. 18 , the same parts as those ofFIG. 6 are indicated by the same reference numerals and a detailed explanation of them is omitted. - The
electronic camera 70 shown inFIG. 18 comprises the mountingdirection sensing switch 90, the modulation-demodulation section 91, a light-emittingelement 92, a light-receivingelement 93, the power-receivingcoil 75, and an AC/DC converter circuit 94. - The mounting
direction sensing switch 90, when turned on by a projectingpart 78 provided on a stand, outputs the ON signal to aCPU 93. - To cause the light-emitting
element 92 to emit an optical signal corresponding to the data sent to thestand 71, the modulation-demodulation section 91 modulates the transmission data and outputs the resulting data to the light-emittingelement 92. In addition, to send the output corresponding to the optical signal received by the light-receivingelement 93 to aCPU 94 or the like, the modulation-demodulation section 91 demodulates the output into the data that can be processed by theCPU 94 or the like. - The light-emitting
element 92 is an element that emits an optical signal corresponding to the modulated data inputted from the modulation-demodulation section 91 to thestand 71 side. For instance, the light-emittingelement 92 outputs an optical signal corresponding to a USB data or video signal. - The light-receiving
element 93 receives an optical signal (e.g., an optical signal corresponding to USB data, a mounting sense signal, and a stand switch signal) from thestand 71 side, and supplies the output corresponding to the optical signal to the modulation-demodulation section 91. - The power-receiving
coil 75 receives an AC power supply (e.g., 10V AC, 100 kHz) supplied from the power-supplyingcoil 81 of thestand 71, through electromagnetic induction, and outputs the power to the AC/DC converter circuit 94. - The AC/
DC converter circuit 95 converts the inputted AC power supply into a DC power supply (e.g., 6V DC) and outputs the converted DC power supply to thechangeover circuit 48. - The CPU (central processing unit) 93 basically carries out almost the same processes as those carried out by the
CPU 41 shown inFIG. 6 . However, theCPU 93 carries out the following processes because of the difference in configuration. According to the mounting sense signal or stand switch (SW) signal sensed via the light-receivingelement 93 and modulation-demodulation section 91, the CPU carries out the process of determining whether theelectronic camera 70 is mounted on thestand 71, the process of turning on the power supply of theelectronic camera 70, and others. The CPU further carries out not only the process of determining the mounting direction of theelectronic camera 70 according to the output of the mountingdirection sensing switch 90 and selects and sets a suitable operation mode according to the mounting direction but also the process of inhibiting an unsuitable operation mode from being set. The relationship between the mounting direction, the operation mode selected and set according to the mounting direction, and the operation mode inhibited from being set is the same as shown inFIG. 3 . - The
stand 71 shown inFIG. 18 comprises a projectingpart 78, a light-receivingelement 82, a light-emittingelement 83, a modulation-demodulation section 95, an AC/AC converter circuit 96, a high-frequency converter circuit 97, and a power-supplyingcoil 81. - The projecting
part 78 is for turning on the mountingdirection sensing switch 90 when inserted in the engaginghole 74 a in theelectronic camera 70. - The light-receiving
element 82 is an element that outputs to the modulation-demodulation section 95 an output corresponding to the received optical signal (e.g., the optical signal corresponding to a video signal or USB data). - The light-emitting
element 83 is an element that emits an optical signal corresponding to the modulated data supplied from the modulation-demodulation section 95 (e.g., the optical signal corresponding to USB data, stand switch (SW) signal, or the mounting sense signal). The light-emitting element outputs the optical signal corresponding to the mounting sense signal at, for example, specific time intervals. - The modulation-
demodulation section 95 demodulates the output corresponding to the optical signal from theelectronic camera 70 received by the light-receivingelement 82 into a data (signal) that can be processed by a display unit connected to thevideo terminal 51 or an external unit connected to theUSB terminal 52. Furthermore, to cause the light-emittingelement 83 to emit an optical signal corresponding to the data sent to theelectronic camera 70, the modulation-demodulation section modulates the transmission data and outputs the modulated data to the light-emittingelement 83. - The AC/
AC converter circuit 96 converts the commercial AC power supply (e.g., 100V AC) inputted via theAC plug 18 into an AC power supply (e.g., 10V AC) of a specific voltage level suited in supplying power to theelectronic camera 70. - The high-
frequency converter circuit 97 converts the frequency (e.g., 50 Hz) of the AC power supply supplied from the AC/AC converter circuit 96 into a specific frequency (e.g., 100 kHz) suitable for supplying power to theelectronic camera 70 through electromagnetic induction. - The power-supplying
coil 81 is a coil that supplies AC power (e.g., 10V AC, 100 kHz) converted to be a suitable AC voltage and frequency for the power-receivingcoil 75 of theelectronic camera 70. - Next, an example of the operation of the fourth embodiment will be explained. It is assumed that, with both the power switch of the
electronic camera 70 and thestand switch 53 being off, theelectronic camera 70 is mounted on thestand 71 with the front of the camera facing the front or the back of the stand. Then, the optical signal corresponding to the mounting sense signal outputted from the light-emittingelement 83 of thestand 71 at specific intervals of time is sensed by the light-receivingelement 93 of theelectronic camera 70. As a result, it is determined that theelectronic camera 70 is mounted on thestand 71. At this time, the mountingdirection sensing switch 90 of theelectronic camera 70 is turned on or off according to the mounting direction of theelectronic camera 70, thereby outputting a specific sense signal. On the basis of the output, the mounting direction of theelectronic camera 70 is determined. In theCPU 93, not only is a suitable operation mode selected and set according to the determined mounting direction, but also the unsuitable operation modes are inhibited from being set. At this point in time, since the power supply of theelectronic camera 70 is off, the operation mode to be selected and set is the charging mode, regardless of the mounting direction. - When the mounting
direction sensing switch 90 is turned on and it is determined that the camera has been mounted in the first direction, with the camera facing the front of the stand, the reproducing mode and the printing mode are inhibited from being set. In addition, when the mountingdirection sensing switch 90 is turned off and it is determined that the camera has been mounted in the second direction with the back of the camera facing the front of the stand, the photographing mode is inhibited from being set. The mounting direction of theelectronic camera 70 is determined each time theelectronic camera 70 is mounted on thestand 71. - On the other hand, when the
electronic camera 70 is mounted on thestand 71, thestand 71 supplies power to theelectronic camera 70 through electromagnetic induction between the power-supplyingcoil 81 and the power-receivingcoil 75. At this time, the operation mode set in theelectronic camera 70 is the charging mode. Thus, thechangeover circuit 48 switches the power supply destination to the chargingcircuit 49, thereby starting to charge thebattery 47, a secondary battery. When the amount of remaining power of thebattery 47, a second battery, is Full, or when thebattery 47 is a primary battery, charging is not performed. - Here, when the
stand switch 53 is turned on to turn on the power supply of theelectronic camera 70, the signal passes through the light-emittingelement 83 and the light-receivingelement 93 and is notified to theCPU 93. Then, thechangeover circuit 48 switches the power supply destination to thepower supply circuit 50. This allows thepower supply circuit 50 to supply power to each section of theelectronic camera 70. - The operation after the power supply of the
electronic camera 70 is turned on is the same as in the first embodiment. Specifically, according to the determined mounting direction of theelectronic camera 70, the operation mode is changed from the charging mode to the photographing mode or the reproducing mode. In addition, with the PC being connected to the USB terminal of thestand 71, when the user operates the input section of the PC to give a specific instruction to theelectronic camera 70, the operation mode is changed to the. PC communication mode and the operation corresponding to the instruction is carried out. For example, the process corresponding to an image data transfer instruction or the like is carried out. Moreover, with the camera being mounted so that the back of the camera faces the front of the stand, when the user gives a print instruction via the PC, the operation mode is changed to the printing mode and the printing operation corresponding to the instruction is carried out. Depending on the mounting direction, the processes related to the operation modes prevented from being set are not carried out. - As described above, the fourth embodiment has the advantages as explained in the first embodiment, and performs the supply of power from the
stand 71 to theelectronic camera 70 and data transmission and reception between theelectronic camera 70 and thestand 71 in a noncontact manner. - While in the fourth embodiment, the mounting
direction sensing switch 90 has been used to sense the mounting direction of theelectronic camera 70 mounted on thestand 71, the mounting direction may be sensed by using, for example, the aforementioned optical sensor, AE sensor, WB sensor, or the like. Furthermore, like theelectronic camera 57 ofFIG. 8 , theelectronic camera 70 of the fourth embodiment may be provided with a manually-operated lens cover. In this case, for example, on the basis of the relationship shown inFIG. 9 , not only is a suitable operation mode selected and set, but also the unsuitable operation modes are inhibited from being set. -
FIG. 19 is a perspective view showing the external appearance of theelectronic camera system 100 according to a fifth embodiment of the present invention. InFIG. 19 , the same parts as those in the first embodiment (FIG. 1A toFIG. 7 ) are indicated by the same reference numerals and a detailed explanation of them is omitted. Although not shown, it is assumed that theelectronic camera 101 and stand 102 are connected to each other via a connection with the electric contacts shown in the first embodiment or via the noncontacting transmission system shown in the fourth embodiment. - In the fifth embodiment, the stand is composed of two parts, an upper unit and a lower unit. The upper unit on which the electronic camera is mounted is so constructed that it can rotate with respect to the lower unit. As shown in
FIG. 19 , thestand 102 on which theelectronic camera 101 is mounted is composed of two parts, anupper unit 102 a and alower unit 102 b. Theupper unit 102 a is provided so as to be capable of rotating via a rotating table 103 with respect to thelower unit 102 b so that either the front or the back of theupper unit 102 may face the front of thelower unit 102 b. - In the fifth embodiment, the mounting direction signal of the camera with respect to the
upper unit 102 a and the signal representing the direction of theupper unit 102 a with respect to thelower unit 102 b are sent from thestand 102 to theelectronic camera 101. On the basis of the two signals, the direction of theelectronic camera 101 with respect to thelower unit 102 b can be sensed. - According to the mounting direction of the
electronic camera 101 with respect to thelower unit 102 b, for example, a suitable operation mode can be selected and set and unsuitable operation modes, as shown inFIG. 7 andFIG. 9 , can be prevented from being set. - As described above, with the fifth embodiment, the user can change the mounting direction of the
electronic camera 101 without removing theelectronic camera 101 from thestand 102 by just rotating theupper unit 102 a on which theelectronic camera 101 has been mounted, with respect to thelower unit 102 b. Even this configuration enables not only a suitable operation mode to be selected and set automatically but also the unsuitable operation modes to be automatically prevented from being set. - In the fifth embodiment, the mounting direction of the
electronic camera 101 with respect to theupper unit 102 a may be fixed in such a manner that, for example, the front of the camera always faces the front or the back of theupper unit 102 a. This makes it possible to determine the mounting direction of theelectronic camera 101 with respect to thelower unit 102 b by sensing only the direction of theupper unit 102 a with respect to thelower unit 102 b. - [1] The electronic camera system described in the embodiments comprises an

At the top of thecamera body 111, arelease button 115 is provided. In the base, atripod mounting hole 116, a battery-loading opening 117, and others are made. Through the battery-loading opening 117, asecondary battery 118 is loaded into the battery compartment in thecamera body 111. - At the left side face of the
camera body 111 when viewed from the front, aconnector cover 119 is provided in such a manner that it can slide as shown by the arrow. Behind theconnector cover 119, aconnector 121 is provided. Theconnector 121 is connected to thesecondary battery 118 via acharging circuit 123 explained later and further can be coupled with aconnector 131 of acamera stand 130, explained later. - At the back of the
camera body 11, an LCD (liquid-crystal display) 122 is provided as display means for reproducing and displaying the images or the like recorded on a recording medium or the like. In thecamera body 111, acircuit board 120 is provided. On thecircuit board 120, a chargingcircuit 123 and alens barrel 124 having the photographinglens window 112 at its tip, etc. are provided. -
FIG. 21A andFIG. 21B show a state where theelectronic camera 110 of the sixth embodiment is mounted on astand 130 so that the back of the camera faces the front of the stand.FIG. 21A is a side view andFIG. 21B is a front view. As shown inFIG. 21A andFIG. 21B , theelectronic camera 110 is placed in a camera mountingconcave section 132 of thestand 130 with its left side facing down in a position differing from the position in use, that is, a vertical position. In such a mounting state, theconnector 121 mounted on the left side face of the camera body 111 (located in the lower half of the figure because thecamera body 111 is in a vertical position) is coupled with aconnector 31 provided on the base of the camera mountingconcave section 132 on the stand side. - The

FIGS. 22A to 22C show the change in orientation of the displayed image on theLCD 122 when theelectronic camera 110 is changed from the normal-use position to the stand-mounted position. As shown inFIG. 22A , it is assumed that, with thecamera body 111 held in the normal-use position, a specific image is displayed in an upright position on theLCD 122. To mount theelectronic camera 110 on thestand 130, thecamera body 11 is turned through 90° into a vertical position, as shown inFIG. 22B . Then, the displayed imaged on theLCD 22 is in a 90° turn state at a result of the change of the position of thecamera body 111. As shown inFIG. 22C , however, mounting thecamera body 111 on thestand 131 causes theconnector 121 on the electronic camera side to connect to theconnector 131 on the stand side. In this state, the displayed image on theLCD 122 is displayed in an upright position as shown in the figure, regardless of the fact that thecamera body 111 is changed from the horizontal position to the vertical position. However, in the upper and lower parts of the vertically-positioned display screen, band-likeundisplayed areas 122X, called black back or blue back, appear. -
FIG. 23 is a block diagram showing a configuration of the control system of the electronic camera system including theelectronic camera 110 with the displayed=image direction=changing function and thestand 130. The part enclosed by a dashed line in the upper part of the figure indicates theelectronic camera 110 and the part enclosed by a dashed line in the lower part of the figure indicates thestand 130. - First, the
stand 10 will be explained. Thestand 130 incorporates an AC/DC converter for converting a commercial AC power supply (e.g., 100V AC) into a lower voltage rectified power supply. The stand includes a video output terminal (jack) VID and a serial bus connection terminal (jack) USB as a signal communication terminal. Then, the AC/DC converter 136, video output terminal (jack) VID, and serial bus connection terminal (jack) USB are electrically connected to each section of thecamera body 111 via theconnector 131 on the stand side and theconnector 121 on the electronic camera side. - One of the
connector 121 on theelectronic camera 110 side and theconnector 131 on thestand 130 side is a plug and the other is a jack. They are capable of being connected detachably. With theconnector 121 andconnector 31 connected to each other, each section of theelectronic camera 110 is connected to each section of thestand 130 via the corresponding connector terminal. - Specifically, a ground section E1 on the stand side is connected to a ground section E1 on the electronic camera side via a connector terminal a. The AC/
DC converter 36 on the stand side is connected to thechangeover circuit 171 in thepower supply section 170 on the electronic camera side via a connector terminal b. A ground section E2 on the stand side is connected to a potential control terminal P in the standmount sensing circuit 160 on the electronic camera side via a connector terminal d. The serial bus connection terminal (jack) USB on the stand side is connected to the serial bus connection terminal (jack) USB on the electronic camera side via a connector terminal e. Similarly, the video output terminal (jack) VID is connected to the video output terminal (jack) VID on the electronic camera side via a connector terminal f. - Next, the
electronic camera 110 will be explained. Theelectronic camera 110 has a photographingoptical system 140 including a photographinglens 141, amechanical shutter 142, a photographing element (e.g., CCD photographing element) 143 in thecamera body 111. The electric signal corresponding to the subject image picked up by the photographingoptical system 140 is converted into image data at a photographingcircuit 144. The image data is supplied via a data bus 150 to atemporary storage memory 151 composed of DRAM or the like, which stores the image data temporarily. The temporarily stored image data is subjected to a compression process at animage processing unit 152 and then is stored in animage recording medium 153 composed of a flash memory or the like. Information SB about the direction of each image is attached to the image data stored in theimage recording medium 153. - The image data stored in the
image recording medium 153 is read from the recording medium in reproduction. After the image data is subjected to an expansion process at theimage processing unit 152, the resulting data is stored temporarily in thetemporary storage memory 151. Then, the temporarily stored reproduced data is supplied via anLCD driver 155 to theLCD 22, which displays images. The reproduced image data can also be output via avideo driver 56 at the video output terminal VID, to an external display unit (not shown). This makes it possible to display the data on an external monitor at any time. - When the display image data is supplied via the
LCD driver 155 to theLCD 122, which displays the image, or outputted via thevideo drover 156 at the video output terminal VID, from which the data is supplied to the external display unit (not shown) for displaying the image, the direction of the displayed image is changed suitably by image direction changing means, explained later, with the result that the image is displayed in an upright position. - The
LCD 122 includes aclock display section 122T for displaying the clock data supplied from aclock section 157 the direction of a clock representation displayed on theclock display section 122T can also be changed by clock display changing means included in the image direction changing means. - In
FIG. 23 ,reference numeral 158 indicates an operation program section for causing theCPU 154 to carry out a specific operation.Reference numeral 159 indicates an interface for exchanging signals via the serial bus connection terminal (jack) USB. - The
electronic camera 110 includes a standmount sensing circuit 160 as sensing means for sensing whether thecamera body 111 is mounted on thestand 130. The standmount sensing circuit 160 applies a positive potential to a terminal 161 to one port of theCPU 154 via aresistance element 162. With thecamera body 111 being mounted on thestand 130, when theconnectors resistance element 161, or the potential control end P connected to theCPU 54, is dropped to the ground potential. By doing this, stand mounting information SA indicating that thecamera body 111 is mounted on thestand 130 is supplied to theCPU 154. - The
power supply section 170 is composed of thechangeover circuit 171, apower supply circuit 172, the chargingcircuit 123 including a battery remainingpower sensing circuit 173, and thesecondary battery 118. When the AC/DC converter 136 of thestand 130 inputs a rectified power supply of a specific level, thepower supply section 170 supplies the rectified power to each section of thecamera body 111 by way of thechangeover circuit 171 andpower supply circuit 172. When thestand 130 does not input the rectified power supply, the direct-current power supply from thesecondary battery 118 is supplied to each section of the camera body via thepower supply circuit 172. Furthermore, when the battery remainingpower sensing circuit 173 senses that the amount of remaining power of thesecondary battery 118 has dropped below a certain level, the chargingcircuit 123 charges thesecondary battery 118. - An input specify
section 181 as the camera control section includes various setting switches, including a switch that responds to therelease button 115. - Hereinafter, the image displaying operation of the
electronic camera 110 in the sixth embodiment configured as described above will be explained by reference to a flowchart shown inFIG. 24 . - Step ST1: The
camera 110 is set in the reproducing mode to perform the operation of displaying the images recorded in theelectronic camera 110. - Step ST2: Specific image data whose frames are specified is read from the
image recording medium 153 and undergoes an expansion process at theimage processing unit 152 and the resulting data is stored in thetemporary storage circuit 151. - Step ST3: It is determined whether stand mounting information SA is present or absent. Stand mounting information SA indicates whether the
electronic camera 110 is mounted on thestand 130, in other words, whether theconnector 121 and theconnector 131 are coupled with each other. If it is determined that stand mounting information SA is present, control proceeds to step ST4. If it is determined that stand mounting information SA is absent, control goes to step ST7. - Step ST4: Information SB representing the direction of an image is acquired. Information SB is attached to the image data stored in the
image recording medium 153. For example, as shown inFIG. 25 , the following four types are used as image mounting information SB: [0°] (upright state), [+90°] (a 90° turn to the right), [+180°] (a 180° turn to the right), and [+270°] (a 270° turn to the right). - Step ST5: On the basis of the stand mounting information SA (present) and the image direction information SB, the
CPU 54 gives the following display direction change instruction SC to either theLCD driver 155 or thevideo driver 156, thereby carrying out the process of rotating images. - (11) When SA is “present” and SB is [0°]: the CPU gives the
LCD driver 155 an instruction to make a 270° turn to the right, and thevideo driver 156 an instruction to make a 0° turn to the right. - (12) When SA is “present” and SB is [+90°]: the CPU gives the
LCD driver 155 an instruction to make a 180° turn to the right, and thevideo driver 156 an instruction to make a 270° turn to the right. - (13) When SA is “present” and SB is [+180°]: the CPU gives the
LCD driver 155 an instruction to make a 90° turn to the right, and thevideo driver 156 an instruction to make a 180° turn to the right. - (14) When SA is “present” and SB is [+270°]: the CPU gives the
LCD driver 155 an instruction to make a 0° turn to the right, and thevideo driver 156 an instruction to make a 90° turn to the right. - Step ST6: As a result of the operation of each of the
drivers LCD 122 and the external display unit. That is, when thecamera body 111 is mounted on thestand 130, the direction of the displayed image is changed on the basis of the information SB on the direction of the image so that a representation may be suitable for a position (a vertical position) different from the normal-use position, or the normal-use position (a horizontal position). - In
FIG. 26 (a) to (d) show an example of the change of the direction of the image displayed on theLCD 122. As shown in the figure, according to the contents of the image direction information SB, the direction of the displayed image is changed suitably when the camera is mounted on the stand and after the image rotating process is completed. Explanation ofFIG. 24 will be resumed. - Step ST7: When it is determined that the stand mounting information SA is “absent” in step ST3, the information SB representing the direction of the image attached to the image data stored in the
image recording medium 153 is acquired as in step ST4. - Step ST8: On the basis of the stand mounting information SA “absent” and the image direction information SB, the
CPU 154 gives theLCD driver 155 orvideo driver 156 the following display direction change instructions SC, thereby performing the process of rotating the image: - (21) When SA is “absent” and SB is [0°]: the CPU gives the
LCD driver 155 an instruction to make a 0° turn to the right, and thevideo driver 156 an instruction to make a 0° turn to the right. - (22) When SA is “absent” and SB is [+90°]: the CPU gives the
LCD driver 155 an instruction to make a 270° turn to the right, and thevideo driver 156 an instruction to make a 270° turn to the right. - (23) When SA is “absent” and SB is [+180°]: the CPU gives the
LCD driver 155 an instruction to make a 180° turn to the right, and thevideo driver 156 an instruction to make a 180° turn to the right. - (24) When SA is “absent” and SB is [+270°]: the CPU gives the
LCD driver 155 an instruction to make a 90° turn to the right, and thevideo driver 156 an instruction to make a 90° turn to the right. - Step ST9: As a result of the operation of each of the
drivers LCD 122 and the external display unit. That is, when thecamera body 111 is not mounted on thestand 130, the direction of the displayed image is changed on the basis of the information SB on the direction of the image so that a representation may be suitable for the normally used position (a horizontal position). - Step ST10: It is determined whether to display another image. To display another image, control returns to step ST2. If another image is not displayed, control proceeds to step ST11.
- Step ST11: The series of image displaying operations in the image-reproducing mode is completed.
- When the clock data outputted from the
clock section 157 incorporated in theelectronic camera 110 is displayed together with the displayed image on theclock display section 122T or the like of theLCD 122, the direction of the clock representation is changed and controlled in the same manner as changing the direction of the image. The changing control in this case is performed by clock display changing means included in the image direction changing means. Because the changing means is the same as the image direction changing means, its explanation is omitted. - The
electronic camera 110 described in the sixth embodiment includes the following modifications. -
- In a case where the image direction information SB attached to the image, for example, when the
camera body 111 is mounted on thestand 130 on the basis of only the stand mounting information SA, the direction of images is changed uniformly (in the case of display on theLCD 122, the images are given a +270° turn, and in the case of an external display unit, the images are given a 0° turn). - In a case where the displayed image does not stand upright only by making the uniform change as when pictures are taken with the camera held vertically, for example, an operation button provided on the stand enables the image to be adjusted so that it may stand upright.
- There is provided manual operation means which enables the displayed image to be turned at intervals of 90° to the right or the left each time a push button is operated.
- A configuration obtained by suitably combining the configuration of each of the first to fifth embodiments. For example, one combination may be such that, when the electronic camera is mounted in the second direction and the reproduction mode is selected and set, the direction of the image is changed.
- In a case where the image direction information SB attached to the image, for example, when the

electronic camera 110, when thecamera body 111 is mounted on thestand 130, the direction of the displayed image on the display means 122 can be changed to an upright position. Thus, the displayed image is very easy to see, regardless of the fact that thecamera body 111 is mounted on thestand 130 in a position different from the position when the camera is being used. - [2] The

electronic camera 110, even when photographing is done with thecamera body 111 being held in various positions, the direction of the displayed image on theLCD 122 is changed automatically to a suitable direction according to the position of thecamera body 111 during photography at the time when thecamera body 111 is mounted on thestand 130. This makes it easy to view the displayed image. - [3] The

electronic camera 110, the displayed image is always easy to view, even when the position of thecamera body 111 is the normally used position (horizontally long position) or the stand mounting position (or vertically long position), or even when the display image data is outputted to an external display unit, with the camera being mounted on thestand 130, and the external display unit displays the image data. -
FIG. 27A andFIG. 27B show a schematic configuration of an electronic camera system according to a seventh embodiment of the present invention.FIG. 27A is a side view showing a state where an electronic camera is mounted on astand 130 in such a manner that the back of the camera faces the front of the stand.FIG. 27B is its front view. In the seventh embodiment, the same component parts as those in the sixth embodiment (FIGS. 20A to 26) are indicated by the same reference numerals and a detailed explanation of them are omitted. - As shown in
FIG. 27A andFIG. 27B , theelectronic camera 110 is mounted in a position different from the position in use, that is, in a vertical position, in such a manner that the left side face viewed from the front of thecamera body 111 is inserted in a camera mountingconcave section 132 of thestand 130.

Theoperation section 138 is connected to theCPU 54 on the electronic camera side via the connector terminal c of theconnector 131 on the stand side and the corresponding terminal c of theconnector 121 on the electronic camera side. - Next, the
electronic camera 110 will be explained. When the display image data is supplied via theLCD driver 155 to theLCD 122, which displays the data, the brightness of the displayed image is changed suitably by the brightness changing means according to the position of theelectronic camera 110. Then, as described later, when it is sensed that thecamera body 111 is mounted on thestand 130, control means composed of theCPU 154 andLCD driver 155 controls the brightness changing means. As a result, the direction of the field angle at theLCD 122 is changed to a setting value (direction) suitable for theelectronic camera 110 mounted on the stand. - In
FIG. 29 , reference numeral 257 indicates an EEPROM for storing the initial setting information about theelectronic camera 10 and reference numeral 281 is an input specify section having various setting switches, including a switch that responds to therelease button 115 and a switch that responds to a brightness adjust button (not shown). - Hereinafter, the brightness changing control operation of the
electronic camera 110 in the seventh embodiment configured as described above will be explained by reference toFIG. 30A ,FIG. 30B , and others. - The
electronic camera 110 is set in the reproducing mode to display the image recorded in theelectronic camera 110. Then, specific image data whose frames are specified is read from theimage recording medium 153 and undergoes an expansion process at theimage processing unit 152. The resulting data is stored in thetemporary storage circuit 151. - When the
electronic camera 110 is not mounted on thestand 130 and thecamera body 11 is in the normal position, theconnectors sensing circuit 160 is kept at a high potential+V. Thus, the stand mountingsensing circuit 160 informs theCPU 154 of stand mounting information SA “absent.” Consequently, theCPU 154 informs theLCD driver 155 of brightness changing instruction SC “absent.” Therefore, the image based on the reproduce image data stored in thetemporary storage circuit 151 is displayed on theLCD display section 22 at a standard brightness (of a suitably set value), for example, at [−1] (seeFIG. 28A ). Thus, as shown inFIG. 30A , the displayed image can be seen well in the range of a field angle of α. - When the
electronic camera 110 is mounted on thestand 130 and held at an angle of θ, with an inclination of about 10° to the horizontal plane, theconnectors sensing circuit 160 is forced to drop to the ground potential. Accordingly, the stand mountingsensing circuit 160 informs theCPU 154 of stand mounting information SA “present.” Therefore, theCPU 154 informs theLCD driver 155 of brightness changing instruction SC “present.” As a result, the brightness is changed so that the direction of the field angle at the LCD 222 may be changed to a setting value (direction) corresponding to the position in which thecamera body 111 is mounted on thestand 130. - Therefore, the image based on the reproducing image data stored in the
temporary storage circuit 151 is displayed on theLCD 122 at the brightness changed and set as described above, for example, at [+3] (seeFIG. 28B ). Thus, as shown inFIG. 30B , the image can be seen well in the range of a field angle of β (equal to α) at the setting value (direction) changed according to the position in which thecamera body 11 is mounted on the stand 30 (with an inclination of, for example, about 10° to a horizontal plane). - The setting value of the direction of the field angle can be adjusted and set by manually operating the
operating section 138. Specifically, to make the brightness a little lower than the setting value, thebrightness decrease button 138 a has only to be pressed a desired number of times. To make the brightness a little higher than the setting value, thebrightness increase button 138 b has only to be pressed a desired number of times. Then, pressing thesetting button 138 c determines the adjusted value. - In the seventh embodiment, while in the setting of brightness, the value for normal use and the value for use with the camera mounted on the stand have been set separately, the latter value may be obtained by adding a specific correction value to the setting value for normal use. This makes it possible to automatically set and change the setting value for use with the camera mounted on the stand, just by carrying out the setting and changing operations for normal use.
- The
electronic camera 110 and stand 130 shown in the seventh embodiment includes the following modifications. One modification is such that thecamera body 111 is mounted on thestand 130 in a horizontally long position. Another modification is such that mechanical means, for example, a mechanism for changing the direction of the field angle by rotating theLCD 22 itself is used as field angle changing means, in place of electrical means, such as brightness changing means. - Furthermore, the configuration of the seventh embodiment may be combined suitably with the configurations of the first to fifth embodiments. For instance, one combination may be such that, when the electronic camera is mounted in the second direction and the reproducing mode or the like is selected and set, the brightness is changed. In addition, the configuration of the seventh embodiment may be combined with that of the sixth embodiment to mount the electronic camera on the camera stand, thereby changing both of the direction of the image and the brightness.
- [1] The
electronic camera 110 described in the embodiment is configured so as to be capable of being mounted on achargeable camera stand 130 and is characterized by comprising acamera body 111, an LCD 22 (display means) which is provided on thecamera body 111 and displays an image based on image data, field angle changing means (LCD driver 55, LCD display section 22) for changing the direction of field angle at theLCD 122, sensing means (stand mount sensing circuit 160) for sensing that thecamera body 111 is mounted on thestand 130, and, control means (CPU 154, LCD driver 155) which, when the sensing means 160 senses that thecamera body 111 is mounted on thestand 130, controls the field angle changing means to change the direction of field angle to a setting value corresponding to the position in which thecamera body 111 is mounted on thestand 130. - In the
electronic camera 110, when thecamera body 111 is mounted on thestand 130, the direction of field angle at theLCD 122 is changed automatically to a setting value corresponding to the position in which thecamera body 111 is mounted on thestand 130. Therefore, even when thecamera body 111 is mounted on thestand 130, inclining at a specific angle to the latter, the displayed image on theLCD 122 is easy to view. - [2] The
electronic camera 110 described in the embodiment and item [1] is characterized in that the field angle changing means (LCD driver 155, LCD 122) is brightness changing means for changing the brightness of theLCD 122. - In the
electronic camera 110, it is possible to change the brightness and control the field angle just by, for example, providing electrical means for controlling the voltage applied to liquid-crystal molecules, which simplifies the configuration of the control system. - [3] The
electronic camera 110 described in the embodiment and item [1] or [2] is characterized in that thecamera body 111 includes an operation section (input specify section 181) which enables the setting value for the direction of the field angle to be changed manually. - In the
electronic camera 110, the user can change and adjust the setting value to the optimum state according to the position in which thecamera body 111 is mounted on thestand 130 or the angle at which the user views theLCD 122. Thus, the setting value can be adjusted to the optimum value at any time. - [4] The camera stand 130 described in the embodiment is the charging
stand 130 provided so as to enable theelectronic camera 110 described in item [1] or [2] to be mounted on the stand and is characterized in that anoperation section 138 which enables the setting value for the direction of field angle to be changed manually is added to theexterior 137, with thecamera body 111 being mounted on thestand 130. - In the
stand 130, with thecamera body 111 being mounted on thestand 130, the user can adjust the setting value for the field angle at theLCD 122 arbitrarily on thestand 130 side, which makes the stand easer to use and excellent in operability. -

In the eighth embodiment, the same parts as those in the sixth embodiment are indicated by the same reference numerals and an detailed explanation of them is omitted. - As shown in
FIG. 31A andFIG. 31B , theelectronic camera 110 is mounted in a position different from the position in use, that is, in a vertical position, in such a manner that the left side face, viewed from the front of thecamera body 111, is inserted in a camera mountingconcave section 132 of thestand 130. In such a mounting state, theconnector 121 mounted on the left side face of the camera body 111 (located in the lower half of the figure because thecamera body 111 is in the vertical position) is coupled with aconnector 131 provided on the base of the camera mountingconcave section 132 on thestand 130 side. On a part of the back of the camera, there is provided a photographing modeselect mode button 125 used for selecting and setting a normal photographing mode or a specific photographing mode for automatic photography as the photographing mode of theelectronic camera 110. - The
camera stand 130 is integrally formed into a truncated-pyramid-like shape made of, for example, hard resin. On the top, the camera mountingconcave section 132 is provided. In a relatively inconspicuous place of thestand 130, for example, in the lower part of the back, power connection jacks 139 a, 139 b are provided. The power connection jacks 139 a, 139 b are designed to be connectable to a power supply outlet (not shown) via a cable (not shown). The power connection jacks 139 a, 139 b, when not in use, cannot be seen directly from the outside, with alid 139 c (where S indicates a control and H indicates a hinge) closed. -
FIG. 33 is a block diagram showing a configuration of the control system of an electronic camera system including theelectronic camera 110 with a specific-photographing-mode-based (or monitor photographing-mode-based) monitor function and thestand 130. InFIG. 33 , the same parts as those inFIG. 29 are indicated by the same reference numerals and an detailed explanation of them is omitted. - The configuration of the
stand 130 is the same as that ofFIG. 23 , so its explanation is omitted. Hereinafter, theelectronic camera 110 will be explained. - A
camera control section 180 in theelectronic camera 110 comprises an input specifysection 381, an LED (light-emitting diode) 182, astrobe control section 183, a strobe light-emittingunit 184, an AF (autofocus)control section 185, an AF (autofocus)motor 186, a diaphragmshutter control section 187, and adiaphragm shutter motor 188. - The input specify
section 381, which responds to themode button 125, includes a mode select switch for selecting and setting the photographing mode of theelectronic camera 110, a release switch that responds to therelease button 115, and other various switches. - The
CPU 154 includes photographing mode select means which, when receiving a mode select switch signal from the input specifysection 381, selects the normal photographing mode or the specific photographing mode for automatic photography from the photographing modes of theelectronic camera 110 according to the mode select switch signal and sets the selected mode. TheCPU 154 further includes monitor photographing means for photographing under photographing conditions that no other people are allowed to notice photographing operations when the specific photographing mode is selected. The monitor photographing means is means for photographing while inhibiting at least one of the following operations: light emission by the strobe light-emittingunit 184, display by theLED display unit 182 andLCD 122, focusing by theAF motor 186 and the moving of the lens for zooming by a zoom motor (not shown), the driving of the diaphragm shutter by thediaphragm shutter motor 188, and sound reproduction and calling. - Hereinafter, the basic operation of the electronic camera system in the eighth embodiment configured described above will be explained by reference to a flowchart shown in
FIG. 34 . - Step ST21: When it is sensed that the
electronic camera 110 is mounted on the stand, stand mounting information SA is obtained. - Step ST22: It is determined whether the photographing mode of the
electronic camera 110 as a result of the operation of themode button 125 is the monitoring mode. If it is not the monitoring mode, control goes to step ST23. If it is the monitoring mode, control proceeds to step ST26. - Step ST23: If the photographing mode is not the monitoring mode, the amount of remaining power of the battery is checked. If the amount of remaining power of the battery is insufficient, control proceeds to step ST24. If the amount of remaining power of the battery is sufficient, control goes to step ST25.
- Step ST24: Charging is done and control returns to step ST23.
- Step ST25: The charging is completed.
- Step ST26: If it has been determined that the photographing mode is the monitoring mode in step ST22, the
CPU 154 sets the monitoring mode. Specifically, AE and AF operations are carried out, thereby setting the amount of diaphragm opening, shutter speed, and focusing suitably. Thereafter, all of the following operations are inhibited: for example, light emission by the strobe light-emittingunit 184, display by theLED display section 182 andLCD 122, focusing by theAF motor 186, the lens movement for zooming by the zoom motor (not shown), the driving of the diaphragm shutter by thediaphragm shutter motor 188, and sound reproduction and calling. - Step S27: It is determined whether the monitoring photography is started at a result of the release button 15 being pressed. If the
release button 115 has not been pressed, control remains there until the button is pressed. - Step S28: When monitoring photography is started, the amount of remaining power of the battery is checked. If the amount of remaining power of the battery is insufficient, control goes to step ST29. If the amount of remaining power of the battery is sufficient, control proceeds to step ST30.
- Step ST29: Charging is started and control goes to step ST30.
- Step ST30: It is checked whether a specific time (e.g., 10 minutes) previously set by a timer has elapsed. Control returns to step ST28 until the specific time (e.g., 10 minutes) has elapsed. Hereinafter, this operation is repeated. When the specific time (e.g., 10 minutes) has elapsed, a photograph instruction is given, which allows control to proceed to step ST31.
- Step ST31: For example, when the switching of the
changeover circuit 71 stops the chargingcircuit 23 from charging the battery because of a photographing operation, control proceeds to step ST32. - Step ST32: Photographing is done in the monitoring mode. The photographed image data is subjected to a compressing process. The resulting data is recorded in the
image recording medium 153 composed of a flash memory. Then, control proceeds to step ST33. - Step ST33: The condition for ending the photography in the monitoring mode is checked. For example, it is checked whether a preset total monitoring time (e.g., 24 hours) has elapsed. If the end condition is not met, control returns to step ST28. Thereafter, photographing is done in the monitoring mode at intervals of, for example, 10 minutes, while charging the battery, until the end condition is met. If the end condition is met, control proceeds to step ST34.
- Step ST34: The amount of remaining power of the battery is checked. If the amount of remaining power of the battery is insufficient, control goes to step ST35. If the amount of remaining power of the battery is sufficient, control goes to step ST36.
- Step ST35: Charging is effected and control returns to step ST34.
- Step ST36: Charging is completed.
- In the eighth embodiment, while operating the
mode button 125 causes the normal photographing mode or the specific photographing mode for automatic photography to be selected from the photographing modes of theelectronic camera 110 and the selected mode to be set, thecamera body 111 may be configured to function automatically as a monitoring camera, when the camera body is mounted on thecamera stand 130. That is, monitoring function automatic setting means may be provided so that, when the stand mountingsensing circuit 160 senses that thecamera body 111 is mounted on thestand 130, theCPU 154 sets the photographing mode of thecamera body 111 to the specific photographing mode, thereby carrying out photography under the conditions that no one else is allowed to notice the photographing operations. -

The ninth embodiment differs from the eighth embodiment in that a primary battery (not shown) is used in place of thesecondary battery 18. Hereinafter, the operation will be explained by reference to the flowchart ofFIG. 9 . - Step ST41: When it is sensed that the
electronic camera 110 is mounted on thestand 130, stand mounting information SA is obtained. - Step ST42: It is determined whether the photographing mode of the
electronic camera 110 as a result of the operation of themode button 125 is the monitoring mode. If it is not the monitoring mode, control proceeds to step ST43. If it is the monitoring mode, control goes to step ST44. - Step ST43: If the photographing mode is not the monitoring mode, the operation is completed.
- Step ST44: If it has been determined in step ST42 that the photographing mode is the monitoring mode, the
CPU 154 sets the monitoring mode. Specifically, AE and AF operations are carried out, thereby setting the amount of diaphragm opening, shutter speed, and focusing suitably. Thereafter, all of the following operations are inhibited: for example, light emission by the strobe light-emittingunit 184, display by theLED display section 182 andLCD 122, focusing by theAF motor 186, the lens movement for zooming by the zoom motor (not shown), the driving of the diaphragm shutter by thediaphragm shutter motor 188, and sound reproduction and calling. - Step S45: It is determined whether the monitoring photography is started at a result of the release button 15 being pressed. If the
release button 115 has not been pressed, control remains there until the button is pressed. - Step S46: A timer checks whether a specific time (e.g., 10 minutes) has elapsed. Control remains there until the specific time (e.g., 10 minutes) has elapsed. When the specific time (e.g., 10 minutes) has elapsed, control proceeds step ST47.
- Step ST47: Photographing is done in the monitoring mode. The photographed image data is subjected to a compressing process. The resulting data is recorded on the
image recording medium 153 composed of a flash memory. Then, control proceeds to step ST48. - Step ST48: The condition for ending the photography in the monitoring mode is checked. For example, it is checked whether a preset total monitoring time (e.g., 10 hours) has elapsed. If the end condition is not met, control returns to step ST46. Thereafter, photographing is done in the monitoring mode at intervals of, for example, 10 minutes, until the end condition is met. If the end condition is met, control proceeds to step ST49.
- Step ST49: The series of operations is completed.
- The configurations of the eighth and ninth embodiments may be combined suitably with the configurations of the first to fifth embodiments. For instance, one combination may be such that, when the electronic camera is mounted in the first direction and the photographing mode is selected and set, the monitoring mode may be selected and set as the specific photographing mode for automatic photography according to the state of the

FIG. 36A andFIG. 36B show a schematic configuration of an electronic camera system according to a tenth embodiment of the present invention.FIG. 36A is a side view showing a state where a camera is mounted on astand 130 in such a manner that the back of the camera faces to the front of the stand.FIG. 36B is its front view. In the tenth embodiment, the same parts as those in the sixth embodiment (FIG. 20A toFIG. 26 ) are indicated by the same reference numerals and an detailed explanation of them is omitted. - As shown in
FIG. 36A andFIG. 36B , theelectronic camera 110 is mounted in a position different from the position in use, that is, in a vertical position, in such a manner that the left side face viewed from the front of thecamera body 111 is inserted in a camera mountingconcave section 132 of thestand 130. In such a mounting state, aconnector 121 mounted on the left side face of the camera body 111 (located in the lower half of the figure because thecamera body 111 is in the vertically long position) is coupled with aconnector 131 provided on the base of the camera mountingconcave section 132 on thestand 130 side. -
FIG. 37 is an enlarged sectional view, with a portion broken away, of a primary part ofFIG. 36A . As shown inFIG. 37 , light projecting means 130L for projecting light onto the photographing system 140 (including photographinglens 141, photographing element 143) of theelectronic camera 110 mounted on thestand 130 is provided in thecamera stand 130. The light projecting means 130L is composed of alight source 137, a reflectingplate 138, and a milk-white plate 139. In the light projecting means, light emitted from thelight source 137 is reflected diffusely by the reflectingplate 138. The diffusely reflected light is caused to pass through the milk-white plate 139, thereby producing uniform light, which is projected stably onto the photographingsystem 140. Moreover, in theelectronic camera 110, there is provided defective pixel sensing means 190 for sensing defective pixels of the photographingelement 143. The defective pixel sensing means 190, which includes atemperature sensor 191, explained later, and a defective pixel sensing and correctingsection 192, is capable of sensing defective pixels accurately and correcting them. -
FIG. 38 is a block diagram showing a configuration of the control system of an electronic camera system including anelectronic camera 110 with a defective pixel sensing and correcting function, and acamera stand 130. - First, the

section 481 in thecamera control section 180 includes a release switch that responds to therelease button 115, a switch that responds to the defective pixelsense instruction button 128, and various other switches. - A
temperature sensor 191 serving as temperature measuring means is connected to theCPU 154. A defective pixel sensing and correctingsection 192 is connected to the data bus 150. Thetemperature sensor 191, defective pixel sensing and correctingsection 192, andEEPROM 157 that stores the addresses of the defective pixels, and defective pixelsense instruction button 128, together with theCPU 154, constitute the defective pixel sensing means 190 of the present invention. The defective pixel sensing means 190 senses defective pixels according to the temperature measured by thetemperature sensor 191 and continuously monitors for defective pixels accurately, while compensating the sensed output level of temperature-dependent defective pixels for temperature. - In the tenth embodiment, the addresses of the sensed defective pixels are stored in the
EEPROM 157. During photography, the data output from the defective pixels in the stored addresses is subjected to an interpolation process using the output data on the good pixels around the defective ones. The image data subjected to the interpolation process is subjected to a compression process. Then, the resulting data is stored in theimage recording medium 153. - Hereinafter, a white defective sensing operation and a black defective sensing operation in the electronic camera system of the tenth embodiment configured as described above will be explained by reference to flowcharts in
FIG. 39 andFIG. 40 . First, a white defective sensing operation will be explained by reference to the flowchart ofFIG. 39 . - Step ST51: When the stand
mount sensing circuit 160 senses that theelectronic camera 110 is mounted on thestand 130, stand mounting information SA is obtained. - Step ST52: The temperature around the photographing
element 143 is measured on the basis of the signal from thetemperature sensor 191, provided that the stand mounting information SA has been obtained. - Step ST53: It is determined whether the measured temperature is equal to or lower than a specific level.
- Step ST54: If the result of the determination has shown that the measured temperature has exceeded the specific level, for example, 30° C., the sensing of defective pixels is not done and the sensing operation is stopped.
- Step ST55: If the result of the determination has shown that the measured temperature is equal to or lower than the specific level, for example, 30° C., a defect decision threshold value corresponding to the measured temperature level (range) is set. For example, when the measured temperature is 25 to 30° C., the defect decision threshold value is set to +50 dB with respect to the average output level of good. pixels. Similarly, when the measured temperature is 20 to 25° C., the defect decision threshold value is set to +40 dB with respect to the average output level of good pixels.
- Step ST56: The photographing
element 143 is exposed for a specific length of time (several seconds), with theshutter 142 closed. - Step ST57: The pixels whose output levels have exceeded the defect decision threshold value set according to the measured temperature level (range) are sensed as defective pixels.
- Step ST58: The addresses of the sensed defective pixels are stored in the
EEPROM 157. - Step ST59: The series of defect sensing operations is completed.
- Next, a black defect sensing operation will be explained by reference to the flowchart of
FIG. 40 . - Step ST61: When the stand mounting
sensing circuit 160 senses that theelectronic camera 110 is mounted on thestand 130, stand mounting information SA is obtained. - Step ST62: The temperature around the photographing
element 143 is measured on the basis of the signal from thetemperature sensor 191, provided that the stand mounting information SA has been obtained. - Step ST63: It is determined whether the measured temperature is equal to or lower than a specific level.
- Step ST64: If the result of the determination has shown that the measured temperature has exceeded the specific level, for example, 35° C., the sensing of defective pixels is not done and the sensing operation is stopped.
- Step ST65: If the result of the determination has shown that the measured temperature is equal to or lower than the specific level, for example, 35° C., a defect decision threshold value corresponding to the measured temperature level (range) is set. For example, when the measured temperature is 25 to 30° C., the defect decision threshold value is set to −20 dB with respect to the average output level of good pixels. Similarly, when the measured temperature is 20 to 25° C., the defect decision threshold value is set to −30 dB with respect to the average output level of good pixels.
- Step ST66: The
CPU 154 supplies an optical control signal SB on the basis of a black defect sensing instruction BP via theconnectors DC converter 136 in thestand 130. As a result, the AC/DC converter 136 supplies light-up power SP to thelight source 137 of the light projecting means 130L. Thus, the light projecting means 130L projects uniform light stably to the photographingsystem 40 of thecamera body 111. - Step ST67: The photographing
element 143 is exposed for a specific length of time (an instant), with theshutter 142 open. - Step ST68: The pixels (less bright pixels) whose output levels have dropped below the defect decision threshold value set according to the measured temperature level (range) are sensed as black defective pixels.
- Step ST69: The addresses of the sensed defective pixels are stored in the
EEPROM 157. - Step ST70: The series of defect sensing operations is completed.
- Next, the sensing of defective pixels by the defective pixel sensing means 190 and the timing control of the charging of the built-in
secondary battery 118 by the charging means (e.g., charging circuit 123) will be explained by reference to flowcharts inFIG. 41 andFIG. 42 , respectively. First, control operations when charging is done after the defective pixel sensing operation will be explained by reference to the flowchart ofFIG. 41 . - Step ST81: When the stand
mount sensing circuit 160 senses that theelectronic camera 110 is mounted on thestand 130, stand mounting information SA is obtained. - Step ST82: Defective pixels are sensed by the defective pixel sensing means 190, provided that the stand mounting information SA has been obtained.
- Step ST83: It is determined whether the amount of remaining power of the battery is equal to or larger than a specific amount.
- Step ST84: If it has been determined that the amount of remaining power of the battery is smaller than the specific value, the charging
circuit 123 charges the battery and control returns to step ST83. - Step ST85: When the amount of remaining power of the battery is equal or larger than the specific value in step ST83, the series of control operations is completed.
- Because control is performed as described above, the sensing of defective pixels by the defective pixel sensing means 190 is not affected by a temperature rise due to charging. Therefore, even if temperature compensation is not particularly made using temperature measuring means (including
CPU 154, temperature sensor 191), the sensing accuracy can be maintained at a specific level. Naturally, temperature compensation using temperature measuring means may be made at the same time. - Next, control operations when defective pixels are sensed by the defective pixel sensing means 190 after the charging will be explained by reference to the flowchart of
FIG. 42 . - Step ST91: When the stand
mount sensing circuit 160 senses that theelectronic camera 110 is mounted on thestand 130, stand mounting information SA is obtained. - Step ST92: It is determined whether the amount of remaining power of the battery is equal or larger than a specific value, provided that the stand mounting information SA has been obtained.
- Step ST93: If it has been determined that the amount of remaining power is smaller than the specific amount, the charging
circuit 123 charges the battery and control returns to step ST92. - Step ST94: If it has been determined that the amount of remaining power of the battery is equal or larger than the specific value, the defective pixel sensing means 190 senses defective pixels.
- Step ST95: The series of control operations is completed.
- Since control is performed as described above, the charging means (e.g., charging circuit 123) charges the battery sufficiently and then the defective pixel sensing means 190 senses defective pixels. Therefore, there is almost no possibility that the built-in
secondary battery 118 will be exhausted during the sensing operation. Consequently, there is no possibility that the operation of sensing defective pixels will not be interrupted due to the exhaustion of the battery. In this case, however, it is necessary to make temperature compensation using temperature measuring means. - The configuration of the tenth embodiment may be combined suitably with the configurations of the first to fifth embodiments. For instance, the tenth embodiment may be configured so that the defective pixel sensing mode may be selected and set when the electronic camera is mounted in the second direction. Furthermore, the configuration of the tenth embodiment may be combined with the configurations of the sixth to ninth embodiments.
