Next, the operation of the above embodiment will be described.
[First Operation of Embodiment]
A description will be given of a first operation example in the case where the digital camera 4 is newly brought into the LAN connection setting under the wireless LAN environment by the wireless LAN router 2.

  FIG. 4 shows a processing operation for setting connection to a wireless LAN by the digital camera 4 on the light receiving side of visible light communication (referred to as “Wi-Fi (registered trademark) setting processing” in the figure). This operation is executed after selecting a menu item such as “Wi-Fi connection by visible light communication” in the initial setting menu of the digital camera 4. Regarding this operation, in the digital camera 4, the control unit 19 reads out a corresponding operation program stored in the program memory 21, develops it in the main memory 20, and executes it.

  At this time, one of the wireless LAN routers 2 operates a switch or button for performing visible light communication for wireless LAN setting transmission, and thereby the client device authentication code and wireless LAN setting information, that is, wireless LAN setting information, that is, An SSID (Service Set IDentifier), security information, a MAC (Media Access Control) address, and a password are transmitted by visible light communication.

  At the beginning of the process, the control unit 19 determines whether or not the visible light communication is received based on whether or not there is a pixel whose luminance changes in a predetermined blinking pattern in the image data from the image processing unit 13 ( Step S101).

If it is determined that there is reception of visible light communication (Yes in step S101), the control unit 19 causes the image processing unit 13 to analyze the code pattern of the visible light signal (step S102).
Specifically, the control unit 19 images a device authentication code pattern built in the digital camera 4 in advance and a visible light code pattern for wireless LAN connection setting transmitted from the light emitting unit 2a of the wireless LAN router 2. First, it is analyzed by the processing unit 13 to determine whether or not the client device authentication code pattern included in the code pattern transmitted from the wireless LAN router 2 matches the built-in device authentication code pattern. (Step S103).

  If it is determined that the two authentication code patterns match (Yes in step S103), the control unit 19 determines whether the code pattern by the visible light communication of the wireless LAN setting information is received following the authentication code pattern. Is determined (step S104).

  If it is determined that the wireless LAN setting information code pattern by visible light communication has been received (Yes in step S104), the control unit 19 determines each piece of information for connection setting from the received visible light communication code pattern, that is, The SSID, security information, MAC address, and password are extracted, and wireless LAN connection setting is executed (step S105).

  Thereafter, connection to the wireless LAN is executed based on the set information (step S106), and the setting process shown in FIG. 4 is completed.

  If it is determined in step S101 that no visible light communication is received (No in step S101), if it is determined in step S103 that the two authentication code patterns do not match (No in step S103), and step S104 described above. If it is determined that the code pattern by the visible light communication of the wireless LAN setting information is not received (No in step S104), the setting process in step S105 is not performed, and the connection with the wireless LAN router 2 is not performed. As not to be performed, the wireless LAN connection is made while maintaining the setting state with other hot spots already set at that time (step S106), and the processing of FIG. 4 is completed.

  In the operation example described above, the authentication code of the client device and the wireless LAN setting information are transmitted from the light emitting unit 2a of the wireless LAN router 2. However, without the authentication code of the client device from the wireless LAN router 2, When only wireless LAN setting information is transmitted, the digital camera 4 side skips the determination step of step S103 and confirms that the received code pattern is information for setting the connection to the wireless LAN. Then, the setting may be executed.

[Second Operation of Embodiment]
When the digital camera 4 sets the custom shooting mode based on the shooting condition information from the inkjet multifunction device 3 on the assumption that the LAN connection setting of the digital camera 4 has already been completed in the wireless LAN environment by the wireless LAN router 2. A second operation example will be described.

  FIG. 5 shows a processing operation for setting a custom shooting mode (referred to as “shooting condition setting” in the figure) by the digital camera 4 on the light receiving side of visible light communication. This operation is executed after selecting a menu item such as “setting of shooting conditions from an external device by visible light communication” in the setting menu of the digital camera 4. Regarding this operation, in the digital camera 4, the control unit 19 reads out a corresponding operation program stored in the program memory 21, develops it in the main memory 20, and executes it.

  At this time, in one inkjet multifunction device 3, the user sets an arbitrary image on the scanner unit 43 and then performs a touch operation on the touch input unit 46 that performs visible light communication for shooting condition mode setting transmission. Thus, after the image is scanned by the scanner unit 43, the image analysis unit 48 executes the image analysis process as described above, and the setting information of the custom shooting mode loads the authentication code of the client device from the analysis result. Is transmitted from the light emitting unit 3a.

  At the beginning of the process, the control unit 19 determines whether or not the visible light communication is received based on whether or not there is a pixel whose luminance changes in a predetermined blinking pattern in the image data from the image processing unit 13 ( Step S201).

If it is determined that there is reception of visible light communication (Yes in step S201), the control unit 19 causes the image processing unit 13 to analyze the code pattern of the visible light signal (step S202).
Specifically, the control unit 19 is a device authentication code pattern that is built in the digital camera 4 side in advance, and is used for setting shooting conditions transmitted by the light emitting unit 3 a of the inkjet multifunction peripheral 3 that is analyzed by the image processing unit 13. Based on the visible light code pattern, first, it is determined whether or not the client device authentication code pattern included in the code pattern transmitted from the inkjet multifunction peripheral 3 matches the built-in device authentication code pattern. (Step S203).

  If it is determined that the two authentication code patterns match (Yes in step S203), the control unit 19 receives the code pattern by the visible light communication for setting shooting conditions in the custom shooting mode following the authentication code pattern. It is determined whether or not it has been done (step S204).

  If it is determined that a code pattern by visible light communication for setting imaging conditions has been received (Yes in step S204), the control unit 19 further determines in advance from the stored contents of the program memory 21 depending on the model of the digital camera 4. It is determined whether or not there is an empty custom shooting mode depending on whether or not there is an unset one among the number of custom shooting modes that can be arbitrarily set by the user (step S205).

  If it is determined that there is an unset custom shooting mode and there is still an empty space (Yes in step S205), the control unit 19 receives each piece of information for setting shooting conditions in the received custom shooting mode, for example, color space and white balance. The color temperature and the like are extracted and the setting of the custom shooting mode is executed (step S206), and the setting process shown in FIG. 5 is completed.

  If it is determined in step S201 that no visible light communication is received (No in step S201), if it is determined in step S203 that the two authentication code patterns do not match (No in step S203), in step S204. When it is determined that the received code pattern is not a code pattern by visible light communication for setting shooting conditions (No in step S204), and when it is determined that there is no unset custom shooting mode in step S205 and there is no space ( In step S205 No), the setting process in step S206 is not performed, and the process in FIG. 5 is completed.
