- FIG. 4 is a flowchart explaining the flow of projector control processing performed by the CPU 101. Is. The process shown in FIG. 4 is repeated while the power switch of the projector-equipped mobile phone 10 is turned on.
- the CPU 101 determines whether the opening / closing angle switch 114 is on. When the ON signal is input from the opening / closing angle switch 114 (that is, when the relative angle between the operation unit 1 and the display unit 2 is set to the projection posture of 80 degrees), the CPU 101 makes an affirmative determination in step S11 and performs the step Proceeding to S12, if the ON signal is not input from the opening / closing angle switch 114 (that is, the projection posture is not set), a negative determination is made in step S11, and the determination process is repeated.
- step S12 the CPU 101 determines whether or not the ON signal from the opening / closing angle switch 114 is continued for 2 seconds or more.
- the CPU 101 makes an affirmative decision in step S12 when the ON signal continues for 2 seconds or more and proceeds to step S13, and returns to step S11 when the duration time is less than 2 seconds.
- step S13 the CPU 101 turns on the power of the projector module 6 and proceeds to step S14. Specifically, a command is sent to the power source 109 to start power supply to the projector module 6.
- step S14 the CPU 101 performs initial setting of the projector module 6 and proceeds to step S15.
- the initial setting includes initializing the liquid crystal driving unit 65, causing the lens driving unit 66 to perform a lens shift corresponding to the initial correction value, and maintaining the LED light source 63 off.
- step S15 the CPU 101 causes the projector module 6 to start projection, and proceeds to step S16. Specifically, a command is sent to the liquid crystal drive unit 65 so that the same content as that displayed on the main liquid crystal display 204 is formed on the liquid crystal panel 62, and the display of the main liquid crystal display 204 is turned off. A command is sent to the LED drive unit 64 to turn on the LED light source 63 later.

- the state of the opening / closing angle switch 114 is always monitored during projection by the projector module 6.
- step S17 the CPU 101 determines whether or not the OFF signal from the opening / closing angle switch 114 has been continued for 0.5 second or more. If the off signal continues for 0.5 seconds or longer, the CPU 101 makes an affirmative decision in step S17 and proceeds to step S18. If the duration time is less than 0.5, the CPU 101 returns to step S15. As a result, even if an OFF signal is temporarily output from the opening / closing angle switch 114 by touching the projector-equipped mobile phone 10 during projection, the process does not proceed to step S18.
- step S18 the CPU 101 causes the projector module 6 to end projection and returns to step S11. Specifically, a command is sent to the LED drive unit 64 to turn off the LED light source 63, and the content (initial screen) displayed on the main liquid crystal display 204 before starting projection by the projector module 6 is displayed. Display on main LCD 204 again.

- the projector since the projector is projected when the projection posture continues for 2 seconds, the projector-equipped mobile phone 10 is temporarily in the process of being opened from the folded state to the talking posture or in the process of folding the talking posture force. Therefore, unnecessary projection is prevented even if the relative angle is 80 degrees.
- the projected image Iv is shaped into a square by combining the tilt effect by lens shift and keystone correction using image processing so that the image Iv projected on the screen S does not become trapezoidal. to correct.
- the lens shift amount and keystone correction amount necessary to obtain a rectangular projection image Iv in the projection posture are stored in advance in the CPU 101 as initial correction values, and the initial correction values are set before starting projection. Was automatically corrected (step S14). Therefore, it is not necessary to perform a correction operation while confirming the projected image after the start of projection, and the operation after the start of projection can be simplified, so that the usability as a projector is improved.
- step S17 When step S17 is positively determined, the projection of information by the projector module 6 is automatically terminated (step S18). 0. Since the end requirement is 5 seconds, it is possible to prevent the projection from being terminated unintentionally when touching the projector-equipped mobile phone 10 during projection.
- step S12 of the flowchart in Fig. 4 it may be determined that the projector-equipped mobile phone 10 is stably placed on a table or the like. That is, it is determined whether both the projector-equipped mobile phone 10 is in the projection posture and the projector-equipped mobile phone 10 is stably placed. In this case, if the ON signal from the opening / closing angle switch 114 continues for 2 seconds or more, and the change in the detection signal by the attitude sensor 103 continues for 2 seconds or more and is below the predetermined value, the process proceeds to step S13, and the opening / closing is performed.
- the process returns to step S11.
- the ON signal from the angle switch 114 is less than 2 seconds, or when the change of the detection signal by the attitude sensor 103 exceeds a predetermined value, the process returns to step S11.
- step S12 it may be determined only that the projector-equipped mobile phone 10 is stably placed.
- the process proceeds to step S13. If the change in the detection signal by the posture sensor 103 exceeds the predetermined value, Return to step S11 Like that. Even if only the state where the projector is stably placed is detected, it is possible to reliably determine the situation in which the projector is used and proceed to the projection process. If it is determined that the projector-equipped mobile phone 10 is stably placed and proceeds to the projection process, the projection is terminated when stable placement is not determined. In this case, in step S17, if the state in which the change in the detection signal by the attitude sensor 103 exceeds the predetermined value continues for 0.5 seconds, the process proceeds to step S18 and the projection is terminated.
- the state of force force on which the projector-equipped mobile phone 10 is stably placed is detected using image data obtained by the camera unit 200 instead of using the detection signal from the attitude sensor 103. Also good.
- a subject image is captured by the camera unit 200 every predetermined time.
- the CPU 101 detects the mounting state of the projector-equipped mobile phone 10 by comparing the image data sent from the camera unit 200 with the latest image data every predetermined time. If the difference (time change) from the most recent image data is greater than the predetermined value, it is determined that the projector-equipped mobile phone 10 is not placed. If the time difference is less than the predetermined value, the projector-equipped mobile phone 10 It is determined that it is stably placed.
