  FIG. 4 is a diagram illustrating a situation when the communication device 1 and the mobile device 2 determine wireless communication. FIG. 5 is a diagram for explaining a situation when the communication device 1 transmits content data after wireless communication is established between the communication device 1 and the portable device 2.

  As shown in FIG. 4, first, the communication device 1 displays a QR code image Q1 corresponding to setting information for performing wireless communication with the mobile device 2 in accordance with a predetermined wireless communication standard on the display unit 13. At this time, in the portable device 2, the imaging unit 21 captures the QR code image Q1 displayed on the display unit 13 of the communication device 1 (FIG. 4A). Subsequently, the setting information extraction unit 302 of the mobile device 2 extracts the setting information W1 including the identification information of the communication device 1 included in the QR code image Q1 captured by the imaging unit 21 and the password corresponding to the identification information, and displayed.

  In step S109, when content data is not received from the portable device 2 (step S109: No), the communication device control unit 18 determines whether or not a predetermined time (for example, 5 seconds) has elapsed (step S114). When the communication device control unit 18 determines that the predetermined time has not elapsed (step S114: No), the communication device 1 returns to step S107. On the other hand, when the communication device control unit 18 determines that the predetermined time has passed (step S114: Yes), the communication device 1 proceeds to step S115.

  Subsequently, the display control unit 186 issues a warning indicating that the content data cannot be received from the mobile device 2 or a warning indicating that the mobile device 2 is not performing a specific operation specified by the communication device 1. It is displayed on the display unit 13 (step S115). Thereafter, the communication device 1 proceeds to step S113.

  In step S116, when a release signal is input via the input unit 12 (step S116: Yes), the communication device 1 performs shooting (step S117). Specifically, the communication device 1 causes the imaging unit 11 to perform a shooting operation to generate image data, causes the image processing unit 181 to perform image processing on the image data, and records the image data in the recording unit 15. Execute the process. Thereafter, the communication device 1 proceeds to step S113. On the other hand, when the release signal is not input via the input unit 12 (step S116: No), the communication device 1 proceeds to step S113.
