As illustrated in FIG. 3, the control unit 22 functions as an attachment detection unit 221, a specification acquisition unit 222, and a function restriction determination unit 223 by executing a program stored in the memory 20.

  The attachment detection unit 221 detects that an external device such as the mobile device 100 is attached to the camera 10. For example, the attachment detection unit 221 detects that the portable device 100 is attached to the camera 10 by detecting the engagement between the contact 21 of the camera 10 and the contact 111 of the portable device 100.

  When an external device such as the mobile device 100 is attached to the camera 10, the specification acquisition unit 222 acquires specification information regarding each unit of the external device from the attached external device. For example, when the portable device 100 is attached to the camera 10 as shown in FIG. 1B, the specification acquisition unit 222 displays the specification information stored in the memory 106 from the portable device 100 as the communication unit 19 or the contact 21. To get through.

  The function restriction determination unit 223 has two functions. First, the function restriction determination unit 223 includes the specification information acquired by the specification acquisition unit 222 when an external device such as the mobile device 100 is attached to the camera 10, and the restriction information stored in the memory 20 of the camera 10. Based on the above, it is determined whether or not to restrict the use of each function provided in the camera 10 and the portable device 100 and whether or not the functions of the respective units can be used together. Then, the function restriction determination unit 223 performs function restriction on the unit determined to restrict the use of the function, and stops the power supply to the unit.

  Functions of the camera 10 when the camera 10 and the mobile device 100 operate in cooperation with each other even if the camera 10 or the mobile device 100 does not fall under the export prohibited product or export restricted product specified by the Wassenaar Arrangement. And the function of the portable device 100 may fall under an export-prohibited product regulated by the Wassenaar Arrangement or an export-restricted product. For example, when the camera 10 and the portable device 100 are used together to have an image sensor with a predetermined number of pixels, a level function, and an electronic compass function, the export prohibited products specified in the Wassenaar arrangement, There is a risk of falling under a regulated product.

  The function restriction determination unit 223 detects the function to be regulated in the regulation information based on the specification information acquired by the specification acquisition unit 222 by using the function of the camera 10 and the function of the mobile device 100 in combination. To do. And the function restriction | limiting determination part 223 determines whether use is restrict | limited about the function which comprises those combinations. For example, when the camera 10 includes the level 16 and the portable device 100 attached to the camera 10 includes the electronic compass 107, the function restriction determination unit 223 determines the level of the level 16 based on the restriction information regarding the Wassenaar arrangement. A combination of the function and the function of the electronic compass 107 is detected, and it is determined whether or not the use of the function of the level 16 and the function of the electronic compass 107 is restricted. Then, the function restriction determination unit 223 restricts the function of the unit that is determined to restrict the use of the function and stops the power supply to the unit. The function restriction determination unit 223 can suppress power consumption in the imaging system 1 by stopping power supply.

  Second, the function restriction determination unit 223 includes a unit in which both the camera 10 and the portable device 100 perform functions of the same category when an external device such as the portable device 100 is attached to the camera 10. In this case, the function of either one of the camera 10 and the portable device 100 is restricted. The function category includes, for example, radio wave reception from a GPS satellite, screen display such as a menu screen, connection to the Internet line, acceptance of user input operations, and the like.

  For example, the GPS module 17 of the camera 10 and the GPS module 108 of the portable device 100 both perform a category function of receiving radio waves from GPS satellites. When the portable device 100 is attached to the camera 10, the function restriction determination unit 223 determines whether or not to restrict the use of functions for each of these GPS modules. For example, the function restriction determination unit 223 restricts the use of the function of the GPS module having low reception sensitivity or high power consumption among the GPS module 17 of the camera 10 and the GPS module 108 of the mobile device 100.

  For example, both the display unit 14 of the camera 10 and the display unit 104 of the mobile device 100 perform a category function of screen display. When the portable device 100 is attached to the camera 10, the function restriction determination unit 223 determines whether or not to restrict the use of functions for each of the display units. For example, the function restriction determination unit 223 restricts the use of the function of the display unit having a low screen resolution among the display unit 14 of the camera 10 and the display unit 104 of the mobile device 100. The function restriction determination unit 223 may select to use both of the two display units. For example, the function restriction determination unit 223 may display a captured image on a display unit with a high screen resolution and display a menu screen on a display unit with a low screen resolution. In addition, when the mobile device 100 includes a display unit on the back side, the function restriction determination unit 223 limits the use of the display unit on the back side that is hidden by the main body of the mobile device 100 and cannot be seen. That is, the function restriction determination unit 223 restricts the use of the display unit of the mobile device 100 based on the mounting state of the mobile device 100 with respect to the camera 10.

  FIG. 4 is a flowchart relating to processing executed by the control unit 22 of the camera 10 when the power of the camera 10 is turned on.

When the determination at step S1 is negative. The control part 22 of the camera 10 repeats the process of step S1 until step S1 is affirmed, and when step S1 is affirmed, it progresses to the process of step S2.

  In step S <b> 2, the control unit 22 of the camera 10 acquires the specification information of the mobile device 100 through the contact 21 and the contact 111 by the processing of the specification acquisition unit 222. The control unit 22 of the camera 10 requests the portable device 100 to transmit the specification information of the portable device 100 in response to the camera 10 and the portable device 100 being in an integrated state. . In response to this request, the control unit 112 of the mobile device 100 transmits the specification information of the mobile device 100 to the camera 10. In the present embodiment, the specification information of the mobile device 100 stored in the memory 106 is transmitted to the camera 10.

  In step S <b> 3, the control unit 22 of the camera 10 receives the first and second functions of the function restriction determination unit 223 in accordance with the camera 10 and the mobile device 100 being integrated. It is determined whether or not to restrict use of the functions of the units of the camera 10 and the portable device 100.

  For example, the control unit 22 of the camera 10 determines to restrict the use of the functions of the level 16 of the camera 10 or the electronic compass 107 of the mobile device 100 based on the restriction information regarding the Wassenaar arrangement stored in the memory 20. . Further, the control unit 22 of the camera 10 is provided with a unit in which both the camera 10 and the portable device 100 perform functions of the same category based on the specification information of the portable device 100 acquired in step S2. Detect and determine whether to limit usage for each of those units.

  In step S4, the control unit 22 of the camera 10 determines whether there is a unit determined to restrict the use of the function by the determination in step S3. When there is a unit that is determined to restrict the use of the function, the control unit 22 of the camera 10 makes an affirmative determination in step S4 and proceeds to step S5, and when there is no unit that is determined to restrict the use of the function. A negative determination is made in step S4, and the process proceeds to step S6. For example, if the control unit 22 of the camera 10 has made a determination to limit the use of functions such as the electronic compass 107, the GPS module 108, and the display unit 14 of the camera 10 in Step S3, Step S4 is performed. Make an affirmative decision.

  In step S5, the control unit 22 of the camera 10 restricts the use of each function determined to restrict the use of the function in step S3. For example, if the control unit 22 of the camera 10 has made a determination to restrict the use of functions such as the electronic compass 107, the GPS module 108, and the display unit 14 of the camera 10 in step S3, Limit use. In addition, the control unit 22 and the control unit 112 also stop power supply to each unit that restricts the use of functions, and suppresses power consumption of a power source (not shown).

  In step S <b> 6, the control unit 22 of the camera 10 sets cooperative control between the camera 10 and the portable device 100. For example, when the use of the function of the display unit 14 of the camera 10 is restricted, the control unit 22 of the camera 10 is configured to display the image data image-processed by the ASIC 13 of the camera 10 on the display unit 104 of the mobile device 100.
