Definitions
- the present invention relates to a device for recording information according to the preamble to the appended claim 1.
- a known way of feeding text and image information into a computer is to use a scanner. Scanners of both the stationary and the portable type are available. A stationary scanner is used for scanning whole pages of text and image information, the scanner being passed over the page automatically at a constant speed. This type of scanner is not suitable for scanning selected parts of information on a page. On the other hand, a portable scanner may be suitable for this purpose.
- US 5 301 243 discloses a hand-held scanner for scanning characters from a character sequence on a substrate.
- the scanner which is passed over the characters which are to be read in contact with the substrate, has an optical system which "sees" a small part of the substrate.
- the optical system comprises a CCD type line sensor, which has a plurality of light-sensitive elements arranged in a row.
- OCR software OCR Optical Character Recognition
- OCR Optical Character Recognition
- US 4 949 391 Another type of hand-held scanner for inputting text is described in US 4 949 391. Unlike the one described above, this scanner has a two-dimensional sensor, which records images of the underlying surface when the scanner is passed over the same. The scanner can only be moved in a direction determined by a wheel abutting against the surface. Redundant information is removed from the recorded images, which are subsequently combined into a larger image. The larger image can be analysed in a computer for identifying characters.
- the object of the present invention is to provide a solution to the problem described above.
- the device is adjustable between a first operating mode and a second operating mode, in which images of an area with a first small and a second large size of the information carrier are recorded so that the information on the information carrier can be recorded at different degrees of selectivity.
- the device In the first operating mode, the device is adapted to be passed over the information while recording a plurality of images with partially overlapping contents, which are put together into a composite image of the information and which each are related to an area with the first small 3 size of the information carrier.
- the device is adapted to image the information by means of at least one image which relates to an area with the second large size of the information carrier.
- the device thus has a first mode for recording information at a high degree of selectivity, e.g. individual words or character sequences, and a second mode for recording larger amounts of information at a lower degree of selectivity, e.g. several lines of text or an image, at the same time.
- An advantage of this device is that the user can choose whether he or she wishes to record information at a high or low degree of selectivity. This can be achieved by a simple adjustment of the device. The user can thus first use the device in the first mode for recording a sentence in a text and subsequently adjust it to the second mode and use it for fast recording of an illustration which takes half a page.
- the information carrier can be any two- or three- dimensional object. Of course, it will usually be a sheet of paper.
- the information on the surface may be composed of characters in the form of letters, numbers, or other written characters or symbols, or of various types of images .
- the recording is carried out with the aid of a light-sensitive sensor having a two-dimensional sensor surface.
- a two-dimensional sensor surface refers to the fact that the sensor surface must be able to image a surface with a matrix of pixels so that images with overlapping contents can be recorded.
- the light-sensitive sensor is preferably of the CCD or CMOS type. It can record images in grey scale or in colour.
- the images comprise a plurality of pixels, each having an intensity value .
- the device can be adjusted by the user or automatically by the device. The adjustment involves the adaptation of the device in some manner, e.g. physically or in 4 terms of software, to make it suitable for use in the mode in question.
- the device is preferably provided with indicating means for indicating the size of the imaging area. It is particularly important that the user knows the size of the imaging area in the second mode since this area is larger in that mode. However, the size of the imaging area is preferably indicated in the first mode as well.
- the size of the imaging area can be indicated on the information carrier itself so that the user can see exactly which information will be recorded. It can be indicated by, for example, dots, lines, or colour, etc.
- the indicating can be effected by means of a single luminous spot or by means of a line showing where on a line the recording will commence. What is important is that the user gets an idea of the size of the imaging area.
- the indicating means comprise an illumination means, e.g. a light-emitting diode or a laser diode.
- the imag- ing area is indicated by a plurality of luminous spots between which the imaging area is located.
- a less complicated optical design of the device as well as more accurate image recording are achieved in this way, since no coloured light is recorded in the image. This is par- ticularly important in connection with the use of colour- sensitive sensors.
- Another way of indicating the imaging area can be to show what is located within the field of vision of the device on a display which in this case constitutes the indicating means.
- the indicating means may comprise a display as well as an illumination means for indicating on the information carrier. 5
- the device can be acted upon for continuous adjustment of the size of the area which is to be imaged between the first small size in the first mode and the second large size in the second mode.
- the user can himself determine, e.g. with the aid of a slider control, the exact size of the imaging area, something which can be advantageous, for example, in connection with the recording of images.
- the indicating means is also acted upon in connection with the continuous adjustment so that the user can see how the size of the imaging area changes.
- the change of the size of the imaging area between the first and the second mode can advantageously be effected by utilising a smaller part of the sensor sur- face in the first mode and a larger part of the sensor surface in the second mode. This can be achieved by only saving information from the desired part of the sensor surface.
- the continuous adjustment of the imaging area can also be achieved in this way.
- the indicating means advantageously consist of a display.
- An alternative way of changing the size of the imaging area is to provide the device with a lens means, which is adapted to project the images of the information carrier onto the sensor surface and which is adjustable for changing the imaging area.
- the lens means can comprise one or more lenses. The advantage of this alternative is that it provides better resolution.
- One way of changing the size of the imaging area with the aid of the lens means is to change the focal distance of the lens means. This can be achieved by the lens means being adjustable between a first position in the first mode and a second position in the second mode.
- the lens means can also be continuously adjustable for continuous adjustment of the position of the lens means between the first and the second position, so that an optional size of the imaging area can be obtained.
- the putting-together is preferably carried out both vertically and horizontally. This has the advantage that the device can be held at different angles and even be turned while being passed over the information carrier and yet the images can be put together well enough that the characters in the composite image can be identified and OCR processed.
- the signal-processing unit preferably comprises software for identifying characters in the composite image and for storing the same in the device in character-coded format, e.g. ASCII code.
- the character identification can, for example, be carried out with the aid of a neural network.
- the device may advantageously comprise a transceiver for wireless communication with an external unit.
- the transceiver can be an IR transceiver, a mobile radio transceiver, or some other suitable transceiver.
- the device can advantageously operate as a scanner also in the second operating mode, in which case it is adapted to be passed over the information while recording a plurality of images with partially overlapping contents, which images are put together into a composite image of the information and which each relate to an area of the second large size.

- a casing 1 having approximately the same shape as a conventional highlighter pen.
- One short side of the casing has a window 2, which is intended to be directed at an area on an information carrier which a user wishes to image.
- the informa- tion carrier can, for example, consist of a sheet of paper or some other type of storage medium, from which a user wishes to record information in character or image format .
- the window 2 is somewhat recessed in the casing 1 in order to reduce the risk of scratches or other damage when the device is not in use.
- the casing 1 essentially contains an optics part 3, an electronic circuitry part 4, and a power supply part 5.
- the optics part 3 comprises four light-emitting diodes 6 jointly constituting an indicating means, but of which only two are visible in the Figure, as well as an adjustable lens system 7 and a light-sensitive sensor 8 which constitutes the interface with the electronic circuitry part 4.
- the LEDs 6 are used for indicating the area on the information carrier under the device which can be imaged by means of the device.
- the lens system 7 fulfils two tasks simultaneously. One of its tasks is to project light from the LEDs 6 onto the information-carrying surface towards which the window of the device is directed for defining the imaging area. The light from the LEDs can be seen on the surface in the form of luminous spots.
- the other task of the lens system 7 is to image the area indicated by the device on the light-sensitive sensor 8 as accurately as possible.
- the lens system 7 is adjustable between two positions. The adjustment of the lens system can be effected by means of the same technique as is used in cameras.
- Fig. 3 schematically shows how the device is held over a surface in the first mode and the second mode respectively and how, as a result, two imaging areas of different sizes are provided.
- the lens system 7 is also schematically indicated in the Figure in two different positions corresponding to the first mode and the second mode respectively.
- CCD charge coupled device
- the sensor 8 is mounted on its own printed circuit board 11.
- the power supply to the device is obtained from a battery 12 which is mounted in a separate compartment 13 in the casing.
- the block diagram in Fig. 2 schematically shows the electronic circuitry part 4.
- This comprises a processor 20, which by the intermediary of a bus 21 is connected to a ROM 22, in which the programs of the processor are stored, to a read/write memory 23, which constitutes the 10 working memory of the processor and in which the images from the sensor as well as the characters identified and interpreted are stored in the first mode, to a control logic unit 24, to the sensor 8, as well as to the lens system 7 and the LEDs 6.
- the control logic unit 24 is in turn connected to a number of peripheral units, comprising a display 25, which is mounted in the casing, an IR transceiver 26 for transferring information to/from an external computer, buttons 27, by means of which the user can control the device, as well as an operation indicator 28 comprising, for example, a couple of additional LEDs indicating which mode the device is in and whether or not recording is taking place.
- Control signals to the memories, the sen- sor, and the peripheral units are generated in the control logic unit 24.
- the control logic also handles generation and prioritisation of interrupts to the processor.
- the buttons 27, the IR transceiver 26, the display 25, and the LEDs 6 are accessed by the processor writing and reading in the register in the control logic unit.
- the buttons 27 generate interrupts to the processor 20 when they are activated.
- the device functions as follows. First, the user wishes to record the section of text. He starts the device by pressing a button 27, whereby two of the LEDs 6 are turned on projecting two luminous spots onto the sheet of paper. These luminous spots show the height of the imaging area, thereby indi- eating its size since the imaging area is square. The user places these spots to the left of the first letter in the section of text he wishes to record.
- the proces- sor 20 commands the device to begin recording images at a predetermined frequency, e.g. 25 Hz, whereupon the images recorded by the sensor are stored in the read/write memory 23.
- a predetermined frequency e.g. 25 Hz
- text which is stored in image format requires a large amount of memory space. Consequently, to save memory space in this mode, the characters in the images are identified and stored with the aid of ASCII code.
- the processor 20 turns off the image recording.
- the user can control the device to show the recorded text on the display 25 or to transfer the text to an external computer by the intermediary of the IR transceiver 26.
- the possi- bility of showing the scanned information directly on the screen has proven very important since a user often wishes to verify that the correct information has been scanned.
- the flowchart in Fig. 4 shows how the device is adapted to operate in the first mode.
- the device indicates the imaging area with the aid of luminous spots from the LEDs 6.
- the user moves the luminous spots across the area he wishes to record, whereupon the device records images with overlapping contents and stores them in a current image area in the read/write memory 23.
- the images are stored as images, i.e. with the aid of a plurality of pixels, each having a grey scale value in a range from white to black.
- step 403 if such an image is available. If there is no previous image, the 12 current image is entered directly into a line image area in the read/write memory.
- the overlap position providing the highest overlap measurement as stated above is selected.
- the mean value of the grey scale value of the overlapping pixels is used. In this way, noise can be suppressed in the overlap area.
- the putting-together is thus carried out both vertically and horizontally. If it is detected that, when being put together, the images do not end up on a horizontal line, the composite image is suitably adjusted so that it becomes horizontal, for example by turning the composite image.
- Neural network software is commercially available from, for example, MATLAB Neural Network Toolbox, The MathWorks Inc., 24 Prime Park Way, Natick, MA 01760, USA.
- the user also wishes to record the image included on the sheet of paper.
- the lens system 7 is moved from its position in the first mode to the position required for the second mode. Further, the two LEDs 6 which were previously switched off are turned on.
- the focal distance of the lens system 7 is changed and the four luminous spots move diagonally outwards from the centre of the imageable section, so that a larger image- able section is provided, something which is also shown in Fig. 3.
- the user directs the device so that the luminous spots projected onto the paper surround the image he wishes to record.
- the user can adjust the size of the imaging area by changing the distance to the paper. He then presses the button 27 to activate the device which then records an image of the section between the luminous spots.
- the user can control the device to either show the recorded image on the display 25 or transfer the image to an external computer by the intermediary of the IR transceiver 26. If the image on the paper which the user wishes to record is too big to fit within the sec- tion defined by the luminous spots, the user can record a number of sub- images, which are put together into a larger image in the same way as in connection with the use of the device in the first mode. Subsequently, the text and image information recorded by the user can be shown either on the display 25 of the device or on an external computer. ⁇ to to
