<System configuration>
In the present embodiment, when communication between the digital camera 100 and the smartphone 200 is established, a user can control and operate the digital camera 100 from the smartphone 200 on an application that operates on the smartphone 200. As shown in FIG. 3A, when the smartphone 200 communicates with the digital camera 100 to operate a function, there are two types of communication: Bluetooth communication and Wi-Fi communication. In the digital camera 100 of the present embodiment, the two communications are mutually exclusive and cannot communicate at the same time.

  First, communication switching will be described. First, the smartphone 200 and the digital camera 100 are paired by Bluetooth communication. After the pairing, if the user turns on the power switch of the digital camera 100 or inserts a battery into the digital camera 100 to make the Bluetooth function of the digital camera 100 usable, the digital camera 100 is set to the Bluetooth mode. It sends out an advertisement signal to the surroundings for communication of. The advertisement signal is transmitted with the application ID acquired from the smartphone 200 at the time of pairing.

  The smartphone 200 receives the advertisement signal transmitted from the digital camera 100 by the communication unit 211 and the communication unit 212, determines its own application ID from the advertisement signal data, and determines that the smartphone 200 can be connected to itself. The smartphone 200 issues a Bluetooth connection request to the digital camera 100, and Bluetooth communication between the digital camera 100 and the smartphone 200 is established.

  After the Bluetooth communication is established, when the user requests to execute a function that requires Wi-Fi communication, the smartphone 200 requests the digital camera 100 to connect to the Wi-Fi communication. In the present embodiment, the digital camera 100 and the smartphone 200 communicate directly without passing through another access point. When receiving the Wi-Fi communication connection request from the smartphone 200, the digital camera 100 disconnects the Bluetooth communication and forms a wireless LAN network with the simple access point function. When operating as a simple access point, the digital camera 100 starts transmitting a beacon signal periodically. The smartphone 200 detects the beacon signal and participates in the wireless LAN network formed by the digital camera 100. Then, the digital camera 100 and the smartphone 200 are in a state where data can be transmitted and received through mutual device discovery, device capability acquisition, and the like, and establish Wi-Fi communication. The communication method between the digital camera 100 and the smartphone 200 may be a communication method such as an infrastructure mode in which the digital camera 100 participates in a network formed by an external access point and performs communication on the network.

  In the present embodiment, after pairing, the digital camera 100 and the smartphone 200 are always connected by Bluetooth communication, and wait for a function start request from the user. When the user's request is a function that requires Bluetooth communication, the digital camera 100 and the smartphone 200 execute the requested function without switching communication, but when a function that requires Wi-Fi communication is used, As described above, the communication is switched to perform the requested function.

  Next, communication required for each function will be described. The application according to the present embodiment is divided into a function that operates by power-saving Bluetooth communication and a function that operates by high-speed Wi-Fi communication according to the feature of the function. Since the remote control function (301 in FIG. 3B) operates by Bluetooth communication, the smartphone 200 can operate the remote control function without switching communication from the Bluetooth communication state after pairing. When the time setting function of the camera is used (302 in FIG. 3B), the smartphone 200 switches the communication with the digital camera 100 to Wi-Fi communication and then operates the time setting function of the camera. If the user makes a request to start the remote control function during the Wi-Fi communication between the smartphone 200 and the digital camera 100, the smartphone 200 needs to disconnect the Wi-Fi communication with the digital camera 100 and return to the Bluetooth communication. is there.

  Next, a description will be given of the connection of a plurality of cameras and the functional difference between the cameras depending on the model. As shown at 303 in FIG. 3C, the smartphone 200 can be paired with a plurality of digital cameras 100 by Bluetooth communication and connected. However, when executing a function, the function can be executed with only one camera among the connected cameras. When a function is started by a user while the smartphone 200 is connected to the plurality of digital cameras 100 via Bluetooth communication, the function is operated by the selected camera after the user selects a camera.

  The digital camera 100 that communicates with the smartphone 200 has different functions that can be used on applications depending on the camera model. As shown in FIG. 3 (c) 304, some cameras can use both the remote control function and the time setting function, but one of the functions cannot be used, as in 305 and 306. Some cameras cannot be used. Reference numeral 305 denotes a camera compatible with the remote control function and a camera not compatible with the time setting function.

  As described above, in the application operating on the smartphone 200, the functions that can be used are different depending on the communication state between the smartphone 200 and the digital camera 100 and depending on the model of the communicating digital camera 100 at different times. However, there is a problem in that the situation is difficult to understand.

<Overview of application>
The smartphone 200 displays a menu screen when the application is activated. FIG. 4 is a display example of a menu screen of the smartphone 200. Buttons for operating various functions are arranged on the menu screen. For example, if the user selects and executes 401, the screen transits to a screen displaying a list of thumbnails of image data recorded in the digital camera, and if the user selects and executes 403, a screen for changing the time setting of the digital camera is displayed. Transition.

  In the present embodiment, the smartphone 200 switches the display of the buttons of various functions on the menu screen of the application according to the communication state at that time and the function support status of the camera during communication. If the function cannot be used depending on the state, the buttons are grayed out and displayed as shown at 410 to 413. Such a display state is called an unusable state. When the function can be used depending on the state, the buttons are displayed in an effective state like 401 to 404. Such a display state is called a usable state.

  First, a description will be given of how the display of the button is switched according to the communication state.

  While the smartphone 200 and the digital camera 100 are performing Bluetooth communication, the smartphone 200 displays a function of using Bluetooth communication, a function of using Wi-Fi communication, and a button of any function in a usable state. FIG. 4A shows an example of the display. At this time, when the user selects 404, the smartphone 200 displays a remote control operation screen. When the user selects 401 to 403, the smartphone 200 requests the digital camera 100 to switch to Wi-Fi communication.

  During the Wi-Fi communication between the smartphone 200 and the digital camera 100, the smartphone 200 displays the buttons of the functions that use the Wi-Fi communication in a usable state. During the Wi-Fi communication, the button of the function using the Bluetooth communication is displayed in a disabled state. FIG. 4B is an example of the display. To indicate to the user that the button cannot be used, the button is displayed in a disabled state as shown at 408. Further, when the user selects 408, a message as shown at 409 in FIG. Tell them what they can't do and why.

  Next, a description will be given of how the display of buttons is switched according to the function support status of the camera during communication.

  As described with reference to FIG. 3C, in the present embodiment, the correspondence status of the functions that operate on the application of the smartphone 200 differs depending on the model of the digital camera 100. Then, during the Bluetooth communication, the smartphone 200 can know the corresponding status of the function of the communicating digital camera 100 that uses the Bluetooth communication. Therefore, when the Bluetooth camera is performing Bluetooth communication and the communicating digital camera 100 supports the remote control function, the smartphone 200 displays the buttons in a usable state. FIG. 4A shows an example of the display, and 404 is displayed in a usable state. When Bluetooth communication is being performed and the digital camera 100 in communication does not support the remote control function, the smartphone 200 displays the buttons in an unusable state. FIG. 4B shows an example of the display, and 408 is displayed in an unusable state.

  In the present embodiment, the smartphone 200 can be connected to the plurality of digital cameras 100 via Bluetooth communication. Similarly, in the case of connecting a plurality of cameras, the smartphone 200 sets the buttons of the respective functions to the usable state according to the communication state between the smartphone 200 and the digital camera 100 and according to the model of the communicating camera. Or disabled status. At this time, if any one of the communicating cameras is a model that can use the function, the function is displayed in a usable state. For example, if at least one camera compatible with the remote control function is connected, the smartphone 200 can use the 404 as shown in the display example of FIG. To display.

In the present embodiment, during Bluetooth communication, the smartphone 200 cannot know the corresponding state of the function of the communicating digital camera 100 using Wi-Fi communication, but the Wi-Fi communication. Buttons for functions that use are displayed in a usable state. This is because the button is displayed in a usable state, not because it corresponds to the function using Wi-Fi communication, but because it can be switched to Wi-Fi communication. That is, when a user requests to start a function using Wi-Fi communication, first, the smartphone 200 switches communication with the digital camera 100 to Wi-Fi communication. Thereafter, the smartphone 200 determines whether or not the digital camera in communication supports the function requested by the user, and executes the function if the function is supported.
In a state where the smartphone 200 and the digital camera 100 are not connected, all functions cannot be used. As illustrated in FIG. 4D, the smartphone 200 displays the function buttons 410 to 413 in an unusable state. At this time, if the user selects 410 to 413, a message 414 in FIG. 4E is displayed to prompt connection to the camera.

<Flow of smartphone and camera displaying menu screen after communication is established>
Next, a flow from when the smartphone 200 establishes Bluetooth communication with the digital camera 100 to when an application menu screen is displayed will be described with reference to FIG. Note that the digital camera 100 and the smartphone 200 have been paired in advance.

  The smartphone 200 activates the application, displays a menu screen not connected to the digital camera shown in FIG. 4D on the display unit 206, and starts the flow in FIG. 5A.

  In step S501, the smartphone 200 searches for an advertisement signal of the digital camera 100. In step S502, it is determined whether or not an advertisement signal has been detected. If detected, an advertisement signal is received, and the process proceeds to step S503. The advertisement signal detected here is transmitted by the digital camera 100 in step S551 of FIG. 5B, and the advertisement signal includes a nickname of the digital camera 100 and an ID for specifying the model of the camera. . In step S503, the smartphone 200 transmits a connection request to the digital camera 100 that has transmitted the advertisement signal. At this time, the smartphone 200 stores the nickname of the digital camera 100 and the ID for identifying the model of the camera, which are included in the advertisement signal received in step S502.

In step S504, the smartphone 200 establishes Bluetooth communication with the digital camera 100.
