JP 2002-305567 A

  The mobile phone described in Patent Document 1 switches whether to display an image only on the image display unit or to project on the screen while displaying the image on the image display unit by operating the switch. Operation is troublesome.

An electronic apparatus according to the present invention includes a projector device, an imaging device that captures a subject image and outputs an imaging signal, a movable member that changes at least one of a direction in which the projector device projects an image and a direction in which the imaging device images. And a projection control means for causing the projector device to start projecting an image when the image projection direction and the image capturing direction are reversed by the movable member .

The electronic device according to the present invention, elevation can be omitted switch operation to perform the projection.

The best mode for carrying out the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a perspective view of an electronic camera with a projector according to a first embodiment of the present invention. In FIG. 1, a photographing lens 51, a finder objective window 52, and a flash light window 53 are provided in front of the electronic camera 50 with a projector. A release button 54 is provided on the upper surface of the electronic camera 50 with a projector. On the rear surface of the projector-equipped electronic camera 50, a main liquid crystal display (to be described later), an operation member, and a viewfinder eyepiece window (all not shown) are provided.

  A substantially cylindrical housing 55 is supported on a side surface of the projector-equipped electronic camera 50 by a support portion 56 that can rotate ± 180 degrees, and the housing 55 is configured to be rotatable about the support portion 56 as a rotation center. Yes. The support portion 56 is provided with a click mechanism (not shown) whose rotation angle is, for example, every 10 degrees.

  The housing 55 accommodates a projector module, which will be described later, and the projector module projects information such as an image toward the screen S. The projection direction by the projector module is configured to be variable in the vertical direction by the rotation of the housing 55. The housing 55 is further provided with rotation angle detection means (for example, a switch) for detecting the rotation angle of the housing 55.

  FIG. 2 is a block diagram illustrating the configuration of the electronic camera with projector 50 of FIG. In FIG. 2, the electronic camera with a projector 50 includes an imaging unit 200, a projector module 6, a CPU 101, a memory 102, an attitude sensor 103, an external interface (I / F) 108, a power supply 109, and an operation member 112. A speaker 113, a rotation angle switch (SW) 114, a main liquid crystal display 115, and a microphone 107, and a removable memory card 105 is mounted.

  Based on the control program, the CPU 101 performs predetermined calculations using signals input from the respective units constituting the projector-equipped electronic camera 50, and sends control signals to the respective units of the projector-equipped electronic camera 50. The camera operation and the projector operation are respectively controlled. The control program is stored in a nonvolatile memory (not shown) in the CPU 101.

  The memory 102 is used as a working memory for the CPU 101. The attitude sensor 103 detects the attitude of the projector-equipped electronic camera 50 and sends a detection signal to the CPU 101. Thereby, the CPU 101 acquires top and bottom information (including identification of vertical position shooting and horizontal position shooting) indicating the top and bottom of the image at the time of shooting.

  The memory card 105 is constituted by a nonvolatile memory, and data can be written, saved, and read according to instructions from the CPU 101.

  The microphone 107 converts the collected sound into an electrical signal and sends it to the CPU 101. The audio signal is recorded on the memory card 105 during recording. The external interface 108 transmits / receives data to / from an external device via a cable or cradle (not shown) according to a command from the CPU 101.

  The speaker 113 reproduces sound based on the sound signal output from the CPU 101. The operation member 112 sends an operation signal corresponding to the pressed button to the CPU 101.

  The power source 109 is composed of, for example, a detachable battery pack and a DC / DC conversion circuit, and supplies necessary power to each unit in the projector-equipped electronic camera 50. The rotation angle SW 114 detects the rotation angle of the support portion 56. The rotation angle SW 114 detects the rotation angle and outputs an ON signal (H level) when detecting the angle corresponding to the case where the direction of the projected light beam (projection direction) is set on the back side of the projector-equipped electronic camera 50. Then, an off signal (L level) is output at an angle corresponding to the case where the projection direction is set to a position other than the back side of the electronic camera 50 with a projector.

  The main liquid crystal display 115 displays information such as images and texts according to instructions from the CPU 101.

  The camera unit 200 includes a photographing lens 51, an image sensor 201, a lens driving unit 202, and an imaging unit control CPU 203. As the image sensor 201, a CCD, a CMOS image sensor, or the like is used. The imaging unit control CPU 203 drives and controls the image sensor 201 and the lens driving unit 202 according to instructions from the CPU 101. When receiving a zoom control signal from the imaging unit control CPU 203, the lens driving unit 202 drives a zoom lens (not shown) constituting the photographing lens 51 to the tele side or the wide side according to the control signal. The photographing lens 51 forms a subject image on the imaging surface of the image sensor 201. The imaging unit control CPU 203 causes the image sensor 201 to start imaging, reads the accumulated charge signal from the image sensor 201 after completion of imaging, performs predetermined signal processing, and sends it to the CPU 101 as image data. When projecting a captured image, image data is sent from the imaging unit control CPU 203 to the projector module 6 via the CPU 101. The CPU 101 performs trapezoidal distortion correction processing on the image data projected by the projector module 6. The image data input to the CPU 101 can be recorded on the memory card 105, and the image data and audio data recorded on the memory card 105 are respectively transmitted from the projector module 6, the main liquid crystal display 115, and the speaker 113. It is reproducible.

  The projector module 6 includes a projection lens 61, a liquid crystal panel 62, an LED light source 63, an LED drive unit 64, a liquid crystal drive unit 65, and a lens drive unit 66. The LED drive unit 64 supplies current to the LED light source 63 in accordance with the LED drive signal output from the CPU 101. The LED light source 63 illuminates the liquid crystal panel 62 with brightness according to the supply current.

  The liquid crystal drive unit 65 generates a liquid crystal panel drive signal according to the image data, and drives the liquid crystal panel 62 with the generated drive signal. Specifically, a voltage corresponding to the image signal is applied to the liquid crystal layer for each pixel. In the liquid crystal layer to which a voltage is applied, the arrangement of liquid crystal molecules changes, and the light transmittance of the liquid crystal layer changes. Thus, the liquid crystal panel 62 generates an optical image by modulating the light from the LED light source 63 in accordance with the image signal.

  The lens driving unit 66 drives the projection lens 61 to move back and forth in a direction orthogonal to the optical axis based on a control signal output from the CPU 101. The projection lens 61 projects a light image emitted from the liquid crystal panel 62 toward a screen or the like.

  A projection image by the projector module 6 will be described in detail. The electronic camera with projector 50 automatically starts projection when the self-timer photographing mode is turned on and the direction of the light beam projected by the projector module 6 is set on the back side of the electronic camera 50. FIG. 3 is a diagram illustrating an image Iv projected on the back plate Pb of the chair P when the self-timer photographing is performed with the electronic camera with a projector 50 placed on the seat plate Pa of the chair P.

  In order to make the projection image Iv higher than the surface of the seat plate Pa, it is necessary to make the projection direction from the projector module 6 upward from the seat plate Pa. However, simply by making the projection direction upward, the projection image becomes trapezoidal. turn into. Therefore, the projection lens 61 is shifted by the lens driving unit 66 described above to obtain a tilt effect, and keystone correction (trapezoidal distortion correction) is performed on display data to be projected according to the tilt effect, whereby the projection image Iv is squared. Correct electrically. The lens shift amount and the keystone correction amount are stored in the CPU 101 in advance for each projection angle of the projector module 6 (that is, the rotation angle detected by the rotation angle SW114).

  The electronic camera with a projector 50 projects a mirror image of the through image by the projector module 6 before the main shooting by the self-timer shooting, and projects a normal image of the main shooting image (freeze image) by the projector module 6 after the main shooting by the self-timer shooting. Then, after the freeze image is displayed for a predetermined time, the self-timer shooting mode is canceled and the projection by the projector module 6 is ended.

  4 and 5 are flowcharts for explaining the flow of projector control processing performed by the CPU 101 when the self-timer shooting mode is set to ON and the projector projection mode is set to ON. 4 and 5 are repeated while the projector-equipped electronic camera 50 is set to the shooting mode. In step S <b> 11 of FIG. 4, the CPU 101 determines whether an instruction to set the self-timer shooting mode to ON is given. If an instruction to turn on the self-timer shooting mode is given, the CPU 101 sets the self-timer shooting mode to on, makes an affirmative decision in step S11, and proceeds to step S12 to set the self-timer shooting mode on. If no instruction is given (normal shooting mode), the determination in step S11 is negative, and the process proceeds to step S15. Note that the self-timer shooting mode can be set to ON by operating the operation member 112.

  In step S12, the CPU 101 determines whether or not the projector projection mode is on. The CPU 101 makes an affirmative decision in step S12 when an H level signal is input from the rotation angle SW114 and proceeds to step S13. If an L level signal is input from the rotation angle SW114, the CPU 101 proceeds to step S12. A negative determination is made and the process proceeds to step S15. When the process proceeds to step S13, it is regarded that the projector projection mode is set, and when the process proceeds to step S15, it is regarded that the projector projection mode is not set.

  In step S13, the CPU 101 sends an instruction to turn on the projector, that is, the projector module 6 to start projection, and proceeds to step S14. In step S <b> 14, the CPU 101 sends a command to the liquid crystal driving unit 65 so as to form on the liquid crystal panel 62 a content (mirror image) in which the content displayed on the main liquid crystal display 115 is reversed left and right. A command is sent to the LED drive unit 64 to turn on the LED light source 63 after the display of 115 is turned off. Thereby, the first projection content (initial screen) by the projector module 6 becomes a mirror image of the through image displayed on the main liquid crystal display 115. The content projected by the projector module 6 after the initial screen is a confirmation moving image (mirror image) << through image >> before the main photographing by self-timer photographing that is sequentially updated by the camera unit 200. If the main liquid crystal display 115 is turned off at this time, power consumption can be reduced.

  FIG. 6 is an enlarged view of the projection image Iv of FIG. 3 at this time point. Because of the mirror image projection, the subject A is projected on the left side and the subject B is projected on the right side. On the upper left part of the through image, a timer icon 610 indicating that the self-timer shooting mode is set is projected on the through image.

  In step S15 that proceeds when step S11 or step S12 is denied, the CPU 101 continues to display the through image (normal image) displayed on the main liquid crystal display 115. As a result, the confirmation moving image (normal image) before the main photographing that is sequentially updated by the camera unit 200 is displayed on the main liquid crystal display 115. After step S15, processing corresponding to each mode set by the CPU 101 is performed, but since it is not directly related to the present invention, description thereof is omitted.

  In step S14A, the CPU 101 determines whether or not the projector projection mode is on. The CPU 101 makes an affirmative decision in step S14A when an H level signal is input from the rotation angle SW114 and proceeds to step S16. If an L level signal is input from the rotation angle SW114, the CPU 101 proceeds to step S14A. A negative determination is made and the process proceeds to step S14B.

  In step S <b> 16, the CPU 101 determines whether an on signal is input from a release switch (not shown) that is turned on / off in conjunction with the pressing operation of the release button 54. When the release on signal is input, the CPU 101 makes a positive determination in step S16 and proceeds to step S17. When the release on signal is not input, the CPU 101 makes a negative determination in step S16 and returns to step S11. In the self-timer shooting mode, instead of pressing the release button 54, a release instruction may be given from the outside of the electronic camera 50 with a projector, for example, using a remote control device.

  In step S17, the CPU 101 starts a countdown, sends a command to the projector module 6 to project the count value on the through image, and proceeds to step S18. As a result, the liquid crystal driving unit 65 forms a count value on the liquid crystal panel 62 so as to overlap the through image.

  FIG. 7 is an enlarged view of the projection image Iv of FIG. 3 at this time point. In this case, a count value “8” indicating 8 seconds until the start of photographing is projected onto an area close to the electronic camera with a projector 50 when viewed from the subjects A and B in the projection image Iv (lower left in the example of FIG. 3). Has been.

  In step S18, the CPU 101 determines whether or not the count value by the countdown counter is zero. When the count value becomes 0, the CPU 101 makes an affirmative decision in step S18 and proceeds to step S19. If the count value is not 0, the CPU 101 makes a negative decision and returns to step S17. When returning to step S17, the countdown is continued.

  In step S19, the CPU 101 sends an instruction to end the projection to the projector module 6, that is, the projector module 6, and proceeds to step S20. Specifically, a command is sent to the LED drive unit 64 to turn off the LED light source 63.

  On the other hand, in step S14B, which proceeds after making a negative determination in step S14A described above, the CPU 101 sends an instruction to end the projection to the projector module 6, that is, the projector module 6, and proceeds to step S14C. Specifically, a command is sent to the LED drive unit 64 to turn off the LED light source 63. In this way, after the projector module 6 starts projecting an image, an L level signal is input from the rotation angle SW114, and when the direction of projection and the direction of imaging by the camera unit 200 are not reversed, The image projection by the projector module 6 is finished.

  In step S <b> 14 </ b> C, the CPU 101 determines whether an on signal is input from a release switch (not shown) that is turned on / off in conjunction with the pressing operation of the release button 54. When the release on signal is input, the CPU 101 makes an affirmative determination in step S14C and proceeds to step S14D. When the release on signal is not input, the CPU 101 makes a negative determination in step S14C and returns to step S11.

  In step S14D, the CPU 101 starts a countdown and proceeds to step S14E. In step S14E, the CPU 101 determines whether or not the count value by the countdown counter is zero. When the count value becomes 0, CPU 101 makes an affirmative decision in step S14E and proceeds to step S20. If the count value is not 0, the CPU 101 makes a negative decision in step S14E, and repeats the determination process while continuing the countdown.

  In step S20, the CPU 101 performs exposure measurement and AF measurement. The CPU 101 determines the control exposure based on the exposure measurement result, adjusts the focus based on the AF measurement result, and proceeds to step S21. In step S21, the CPU 101 instructs the imaging unit control CPU 203 to start still image shooting (main shooting), and proceeds to step S21A in FIG.

  In step S21A in FIG. 5, the CPU 101 determines whether or not the projector projection mode is on. The CPU 101 makes an affirmative decision in step S21A when an H level signal is input from the rotation angle SW114 and proceeds to step S22. If an L level signal is input from the rotation angle SW114, the CPU 101 proceeds to step S21A. A negative determination is made and the process proceeds to step S24.

  In step S22, the CPU 101 sends the projector on again, that is, sends an instruction to the projector module 6 to resume projection, and proceeds to step S23. Specifically, the CPU 101 sends a command to the LED drive unit 64 to turn on the LED light source 63. In step S <b> 23, the CPU 101 sends a command to the liquid crystal driving unit 65 so as to form an image (in this case, a normal image) based on the image data sent from the imaging unit control CPU 203 after the still image shooting instruction is given on the liquid crystal panel 62. Then, image data is recorded in the memory card 105. As a result, a confirmation image << freeze image >> after still image shooting (main shooting) is projected from the projector module 6. When a predetermined time (for example, 3 seconds) has elapsed after projecting the shooting confirmation image, the CPU 101 sends an instruction to cancel the self-timer shooting mode to the imaging unit control CPU 203 and sends an instruction to end the projection to the projector module 6. Proceed to S24.

  In step S24, the CPU 101 instructs the LED drive unit 64 to clear (turn off) the self-timer shooting mode and turn off the LED light source 63, and the process proceeds to step S25. In step S25, the CPU 101 turns on the display of the main liquid crystal display 115 and returns to step S11 in FIG. As a result, the confirmation moving image (normal image) before the main photographing that is sequentially updated by the camera unit 200 is displayed on the main liquid crystal display 115.

According to the first embodiment described above, the following operational effects can be obtained.
(1) When the self-timer shooting mode is on and the projector projection mode is on, the projector module 6 is turned on to project a mirror image of the through image. The projector projection mode is regarded as ON when the direction of the light beam projected by the projector module 6 is set on the back side of the electronic camera with a projector 50 (opposite to the shooting direction). In this state, the electronic camera with a projector 50 is disposed between the subjects A and B for observing the projected image and the projected image (back plate Pb), and the subject and the projected image are in opposite directions for the electronic camera with a projector 50. To position. Thus, since the mirror images of the subjects A and B are automatically projected behind the electronic camera 50 with a projector, the subjects A and B can confirm framing without performing a switch operation for starting projection. Furthermore, since the size of the projected image is larger than the display screen of the main liquid crystal display 115 disposed in the electronic camera with projector 50, framing can be sufficiently confirmed even from a position away from the electronic camera with projector 50. Further, since the projected light beam is not emitted to the subject side, the subjects A and B do not feel dazzling.

(2) Since the count value of the self-timer is projected on the through image, the shooting timing can be confirmed even from a position away from the projector-equipped electronic camera 50.

(3) Since the projection position of the count value of (2) is an area close to the electronic camera 50 with a projector when viewed from the subjects A and B (lower left in the example of FIG. 3), the lines of sight of the subjects A and B are It can be guided in the direction of the electronic camera 50 with a projector. If the count value projection position can be changed, the display position of the count value can be appropriately set according to the position of the subject, which is even more preferable.

(4) Since the projector module 6 is turned off in step S19 before exposure measurement (step S20) and photographing (step S21), the amount of light projected by the projector module 6 is prevented from affecting the exposure calculation.

  In the above description, the example in which the self-timer shooting mode is set to ON according to the operation signal from the operation member 112 has been described, but it may be set to ON by a menu operation. FIG. 8 is a diagram showing a display example of the self-timer menu displayed on the main liquid crystal display 115. In order from the top in FIG. 8, self-timer on (timer time is 10 seconds), self-timer on (timer time is 3 seconds), self-timer on (timer time is 10 seconds), projector projection mode on, and self-timer off. Each item is configured to be selectable. In the case of the menu operation, the CPU 101 proceeds to step S13 in FIG. 4 when an operation signal indicating confirmation is input from the operation member 112 in a state where the cursor is designated as the third (self-timer on, projector on) shown in FIG. Configured as follows.

  In the above example, the count value during operation of the self-timer is overlaid on the live view image being projected and displayed as an overlay (step S17). Instead, when the main liquid crystal display 115 is configured to face the front direction (shooting direction) of the electronic camera as shown in FIG. 9, the main liquid crystal display 115 may display the count value. Good. In FIG. 9, the main liquid crystal display 115 of the electronic camera with a projector 50 </ b> A is disposed on the free angle member 57. The free angle member 57 faces the main liquid crystal display 115 in the front direction of the electronic camera with a projector 50A, in the back direction, in the left side direction, in the right side direction, or in the top and bottom directions. It can be directed in either direction.

  When the main liquid crystal display 115 is directed to the front direction of the electronic camera with a projector 50A by the free angle member 57 during the self-timer photographing, the CPU 101 causes the main liquid crystal display 115 to display the count value during the self-timer operation. The projector module 6 projects only a through image. When the main liquid crystal display 115 is not directed in the front direction of the electronic camera with a projector 50A, the count value during the self-timer operation is projected on the through image being projected, and the main liquid crystal display 115 The display is turned off. The orientation of the main liquid crystal display 115 may be determined based on the detection output of this switch provided with an angle detection switch in the rotating portion of the free angle member 57. Further, when the angle detection switch detects that the orientation of the main liquid crystal display 115 is the front direction (shooting direction) of the projector-equipped electronic camera 50A, the projection by the projector module 6 is turned on based on this. May be.

  In the above description, the projection by the projector module 6 is turned off in step S19 before exposure measurement (step S20), but instead of turning off the projector projection, the brightness of the LED light source 63 is lowered to lower the projection luminance. You may do it. Also in this case, the amount of light projected by the projector module 6 is prevented from affecting the exposure calculation.

  In the above description, projection by the projector module 6 is performed when the self-timer shooting mode is on (Yes in Step S11) and an H level signal is input from the rotation angle SW114 (Yes in Step S12). I turned it on. Instead of the self-timer shooting mode, the projection by the projector module 6 may be turned on using the determination result of whether or not the self-shooting mode is on. That is, when the self-photographing mode is on and an H level signal is input from the rotation angle SW114, the projection by the projector module 6 is turned on. Even in the self-photographing mode, the subject and the projected image are positioned in opposite directions for the electronic camera 50 with a projector. The on / off of the self-photographing mode may be set according to an operation signal from the operation member 112 or may be set by a menu operation.

  FIG. 10 is a diagram for explaining a case where the subject C self-photographs in the self-photographing mode by hand-holding the projector-equipped electronic camera 50. The projector module 6 projects an image Iv on the screen S. The projected image Iv in this case is also a mirror image of the through image before the main shooting (still image shooting), and is a normal image of the image “freeze image” shot by the main shooting after the main shooting.

  In the above description, the direction of the projected light beam is directed to a wall or the like located on the back side of the electronic camera 50 with a projector (that is, the direction of the projected light beam is opposite to the direction of shooting with the electronic camera 50 with a projector). An H level signal is output from the rotation angle SW114. Actually, the rotation angle at which the rotation angle SW 114 outputs an H level signal may be appropriately set so as to have an arbitrary angular relationship in accordance with the use state of the electronic camera 50. The rotation angle SW114 is configured to output an H level signal when a preset rotation angle is detected. Further, when the rotation angle is within a certain range (for example, within a range of 80 ° ± 10 °), the rotation angle SW 114 may output an H level signal.

  FIG. 14 is a flowchart for explaining the flow of control processing during a call performed by the CPU 101A. The process shown in FIG. 14 starts when the projector-equipped mobile phone 10 is dialed. In step S51 of FIG. 14, the CPU 101A instructs the communication control unit 110 to perform call processing (communication start instruction), and proceeds to step S52. In step S52, the CPU 101A determines whether or not the call destination is connected to the line. If the line is connected, CPU 101A makes an affirmative decision in step S52 and proceeds to step S53. If the line is not connected, CPU 101A makes a negative decision in step S52 and proceeds to step S54.

  In step S53, the CPU 101A causes the communication control unit 110 to start a call and proceeds to step S55. On the other hand, in step S54, the CPU 101A determines whether or not a cutting operation has been performed. When the disconnection operation signal is input from the first operating member 112A, the CPU 101A ends the calling process and ends the process shown in FIG. 14, and when the disconnection operation signal is not input, the CPU 101A makes a negative determination in step S54 and performs step S52. Return to.

  In step S55, the CPU 101A determines whether or not the projection posture is set. When the on signal is input from the opening / closing angle switch 114A, the CPU 101A makes an affirmative determination in step S55 and proceeds to step S56. When the on signal is not input, the CPU 101A proceeds to step S58 with a negative determination in step S55. In step S58, if the projector module 6 is projecting an image, the CPU 101A turns off the projector module 6 and proceeds to step S59. Specifically, a command is sent to the LED drive unit 64 to turn off the LED light source 63 that is turned on.

  In step S56, the CPU 101A determines whether image data has been received. If an image signal is received from the telephone of the other party, CPU 101A makes an affirmative decision in step S56 and proceeds to step S57. If an image signal is not received, CPU 101A makes a negative decision in step S56 and proceeds to step S59.

  In step S57, the CPU 101A turns on the projector module 6 and proceeds to step S59. Specifically, a command is sent to the power source 109 to start supplying power to the projector module 6 and the liquid crystal driving unit 65 is initialized. The CPU 101A further sends a command to the liquid crystal drive unit 65 so as to form a reproduced image based on the received image signal on the liquid crystal panel 62, and sends a command to the LED drive unit 64 so that the LED light source 63 is lit.

  In step S59, the CPU 101A determines whether shooting is permitted. CPU101A makes affirmation determination of step S59, when imaging | photography of the camera part 200 is permitted, and progresses to step S60. Whether or not photographing is possible is determined by an operation signal from the first operation member 112A. If the photographing of the camera unit 200 is not permitted, the CPU 101A makes a negative determination in step S59 and proceeds to step S62.

  In step S60, the CPU 101A turns on the camera unit 200 and proceeds to step S61. Specifically, a command is sent to the power supply 109 to start supplying power to the camera unit 200, and the imaging unit control CPU 203 starts imaging processing. In step S61, the CPU 101A sends a command to the communication control unit 110 to cause the image data photographed by the camera unit 200 to be transmitted to the call destination, and to display a reproduced image on the main liquid crystal display 204, and proceeds to step S62.

  In step S62, the CPU 101A determines whether or not an instruction to disconnect the line connected to the communication partner (disconnect operation) has been issued. When the cutting operation signal is input from the first operating member 112A, the CPU 101A makes an affirmative determination in step S62 and proceeds to step S63. When the cutting operation signal is not input, the CPU 101A makes a negative determination in step S62 and returns to step S55. When returning to step S55, as long as the projector-equipped mobile phone 10 maintains the projection posture and photographing with respect to the camera unit 200 is permitted, the self-captured image is transmitted to the call destination while projecting an image transmitted from the call destination. At the same time, the self-captured image is also displayed on the main liquid crystal display 204.

  In step S63, the CPU 101A controls the communication control unit 110 to disconnect the line connection with the communication partner, and proceeds to step S64. In step S64, the CPU 101A turns off the camera unit 200 and proceeds to step S65. Specifically, a command is sent to the power supply 109 to end the power supply to the camera unit 200. The reproduction image display by the main liquid crystal display 204 is also ended.

  In step S65, the CPU 101A turns off the projector module 6 and ends the process shown in FIG. The projector module 6 is turned off by instructing the power source 109 to stop power supply to the projector module 6. Note that, as in step S14A of FIG. 4, a step of determining whether or not the projector-equipped mobile phone 10 is in the projection posture may be inserted between any of steps S57 to S62. If the CPU 101A determines that the projector-equipped mobile phone 10 is not in the projection posture in this step, the CPU 101A turns off the projector module 6 and executes the subsequent processing steps.
