When the disc 504 rotates integrally with the base portion 2B, the reflecting portion 510 and the non-reflecting portion 511 alternately pass on the optical axis of the detection light of the photo interrupter 505. For example, when the angle between the adjacent reflecting portions 510 is 1 degree, when the reflected light is further detected five times after the reflected light is detected by the photo interrupter 505, the angle of the cradle body 2A is changed by 5 degrees. I understand that. That is, the tilt angle can be detected based on the number of times the reflected light is detected.

  The angle detection information of the photo interrupter 505 is sent to the control circuit 50 of the digital camera 1 through the cradle control circuit 209 and the camera connector 208 of the cradle body 2A (see FIG. 5). The control circuit 50 performs the trapezoid correction described above according to the detected tilt angle.

  FIG. 9 is a diagram illustrating a modification of the second embodiment. In the cradle 2 shown in FIG. 9, only the placement unit 20 on which the digital camera 1 is placed is configured to be able to change the inclination with respect to the main body 21 of the cradle 2. The tilt angle detection mechanism and the like are the same as those of the cradle shown in FIG.

  As described above, in the cradle 2 of the second embodiment, the tilt angle (projection angle) of the cradle body 2A on which the digital camera 1 is placed and the placement unit 20 can be changed. Therefore, the tilt angle of the digital camera 1 can be easily changed according to the projection conditions, and the digital camera 1 can be stably held with respect to various tilt angles.

-Third embodiment-
10 and 11 are diagrams showing a third embodiment of the cradle 2. FIG. FIG. 10 is a diagram showing the cradle 2 and the remote controller 80 of the present embodiment. The cradle 2 includes operation buttons 280, 282 to 285 for sending instructions to the digital camera 1 in addition to the configuration of the cradle 2 shown in FIG. The LED 281 and the communication unit 286 are provided. The communication unit 286 has transmission and reception functions. The remote controller 80 provided separately from the digital camera 1 and the cradle 2 includes a switching button 81, an adjustment button 82, a setting button 83, an LED 84, and a communication unit 85.

  In the present embodiment, the following five types of operation methods are possible as methods for operating the digital camera 1. In the first operation method, the digital camera 1 is operated by an operation unit provided in the digital camera 1. In the second operation method, an operation signal is transmitted from the remote controller 80 to the digital camera 1 for operation. In the third operation method, the digital camera 1 is placed on the cradle 2 and operated by an operation button provided on the cradle 2. In the fourth operation method, an operation signal is transmitted from the remote controller 80 to the cradle 2 and the digital camera 1 placed on the cradle 2 is operated. The fifth operation method is an operation method in which the cradle 2 is used as a remote controller, and an operation signal is transmitted from the communication unit 286 of the cradle 2 to the digital camera 1 that is not placed on the cradle 2. Of course, the digital camera 1 includes a communication unit for receiving an operation signal from the cradle 2.

  FIG. 11 is a block diagram showing the configuration of the digital camera 1, cradle 2 and remote controller 80. The digital camera 1 is the same as the block diagram shown in FIG. 5 except that the communication unit 113 is provided. The internal configurations of the projector unit 30 and the photographing unit 40 are not shown. The cradle 2 includes an LED 281, switches 280 a and 282 a to 285 a corresponding to the operation buttons 280 and 282 to 285, and a communication unit 286 in addition to the configuration shown in FIG. 5. The remote controller 80 is provided with switches 81 a, 82 a, 83 a corresponding to the switching button 81, the adjustment button 82, and the setting button 83, the LED 84, and the communication unit 85.

  The switch button 81 of the remote controller 80 is operated when switching the operation mode between the camera mode and the projection mode. The switch button 81 is used for a power-on operation when the digital camera 1 is powered off. When the power of the digital camera 1 is on, when the switch button 81 is operated, a switch operation signal is output from the switch 81a. When the adjustment mode is activated in the projection mode, the adjustment mode can be ended by operating the switching button 81.

  The switch button 81 is used for a power-on operation when the electronic camera 1 is powered off. When the power of the electronic camera 1 is on, when the switch button 81 is operated, a switch operation signal is output from the switch 81a. When the adjustment mode is activated in the projection mode, the adjustment mode can be ended by operating the switching button 81.

  The adjustment button 82 is operated when an instruction to acquire an image is issued in the same manner as the release button 104 while the electronic camera 1 operates in the camera mode. When operating in the projection mode, the adjustment button 82 is used when instructing activation of the adjustment mode for setting various settings of the projection image and switching of adjustment contents. Each time the adjustment button 82 is operated, a focus adjustment instruction signal, a light amount adjustment instruction signal, a field angle adjustment instruction signal, and a trapezoid correction instruction signal are cyclically output by the remote control circuit 86 in the above order from the adjustment switch 82a. It is transmitted by the communication unit 85.

  The setting button 83 is an operation button having the same function as the enlargement / reduction button 106 a provided in the digital camera 1. When the setting button 83 is operated, an operation signal is output from the setting switch 83a, and the digital camera 1 performs the process of switching the image projected by the projector unit 30 and the process of changing the adjustment parameter in the adjustment mode. When the setting button 83 is pressed and held, the electronic camera 1 performs zooming adjustment of the photographing lens 401 during operation in the camera mode, and zooming adjustment of the projection image during operation in the projection mode.

  When any of the operation buttons 81 to 83 is pressed by the user, the remote control circuit 86 lights the LED 84. When the LED 84 is lit, the switching button 81, the adjustment button 82, and the setting button 83 are illuminated. If no operation button is operated for a predetermined time, for example, 5 seconds after the operation button is operated, the remote control circuit 86 turns off the LED 84. When any of the above-described operation buttons is operated again while the LED 84 is lit, that is, within 5 seconds from the first operation, various operation signals indicating the operation content are transmitted from the communication unit 85.

  The remote control circuit 86 outputs various signals corresponding to the operation signals output from the switches 81a to 83a to the communication unit 85. The communication unit 85 transmits each signal received from the remote control circuit 86 by, for example, infrared rays. In addition, not only the communication part 85 but communication of the communication parts 113 and 286 is performed using infrared rays.

  On the outer surface of the remote controller 80, an index 87 indicating the correspondence between the light emission color of the LED 84 and the adjustment content in the adjustment mode is printed. The index 87 is printed as “focus adjustment” in red, “light amount” in green, “angle of view” in yellow, “keystone correction” in blue, and the like. Therefore, the user can easily grasp which adjustment content is adjusted by comparing the emission color of the LED 84 and the print color of the index 87.

  On the other hand, the operation button 280 provided on the cradle 2 corresponds to the switching button 81 of the remote control 80, the operation buttons 282 and 283 correspond to the setting button 83 of the remote control 80, and the operation button 284 corresponds to the adjustment button 82 of the remote control 80. To do. The operation button 285 is a delete button used for deleting an image file recorded on the memory card 110. In the block diagram of FIG. 11, an operation switch group 280s corresponding to the operation buttons 280 and 282 to 285 is provided. Thus, since the cradle 2 can transmit an operation signal from the communication unit 286 to the digital camera 1, it can also be used as a remote controller.

  In the above-described embodiment, the digital camera has been described as an example. However, the present invention can be similarly applied to any portable electronic device including a projector unit. In addition, the present invention is not limited to the above embodiment as long as the characteristics of the present invention are not impaired.
