Description

  The present invention relates to a communication device, a communication device control method, and a program.

2. Description of the Related Art In recent years, digital cameras that are connected to a smart device via a wireless LAN (Local Area Network) and can take images by sending and receiving image data and operating an opposite device have been known. At this time, the digital camera and the smart device need to participate in the same network formed by an access point or the like. In general, when participating in a wireless LAN network, a public SSID (Service Set Identifier) is often referred to. However, from the viewpoint of security, there is also an access point having a “stealth function” that intentionally hides the public SSID.
On the other hand, in a communication device that participates in a wireless LAN network that intentionally conceals the SSID, the user needs to separately check the concealed SSID and input it to the communication device. In this case, in order to save the trouble of confirming and inputting the SSID every time, when the user inputs communication parameters such as SSID once, the communication device stores the communication parameters, and thereafter, the user uses the communication used in the past. There are some that only need to be selected from the parameters.

  Note that Patent Document 1 describes the following portable device as a technique related to the display of a wireless LAN access point. The portable device of Patent Document 1 includes setting registration / storage means, use / non-use setting registration means, and display means. The setting registration / storage unit registers / stores settings of a plurality of wireless LAN access points. The use / non-use setting registration unit registers information on use or non-use for each of the wireless LAN access points whose settings are stored in the setting registration / storage unit. The display means displays the registered access point. The display means selectively displays an access point in which use information is registered in the use / non-use setting registration means.

JP 2009-182893 A

Here, when a communication device participating in the wireless LAN network uses an SSID stored in advance, the SSID may be displayed on the display unit of the communication device. Thereby, the user can easily confirm the SSID stored in the communication device among the plurality of surrounding SSIDs, and the convenience for the user is improved.
However, when the SSID is displayed on the display unit of the communication device, the displayed SSID is confirmed by a third party, which is problematic from the viewpoint of security. This is particularly a problem in use cases where the user is not necessarily near the communication device, such as stationary use.

  It is an object of the present invention to enhance security or improve user convenience based on settings.

Further, when the release switch 105a is in a fully pressed state, the second switch SW2 is turned on. Thereby, the first control unit 101 receives an instruction to perform shooting.

The first display unit 106 displays parameters for shooting, displays characters for interactive operation, and the like. Note that the first display unit 106 is not necessarily built in the digital camera 100. The digital camera 100 can be connected to the internal or external first display unit 106 and only needs to have at least a display control function for controlling the display of the first display unit 106.
The first recording medium 110 can record the image data output from the first imaging unit 102.

<Parameter setting process>
Next, the parameter setting process will be described with reference to FIG. 3, FIG. 4, and FIG. FIG. 3 is a sequence diagram of the parameter setting process. FIG. 4 is a diagram illustrating an example of the screen of the digital camera 100. FIG. 5 is a diagram illustrating an example of a screen of the smart device 200.
The parameter setting process is a process for setting various parameters of the digital camera 100 using the smart device 200. The smart device 200 and the digital camera 100 are connected via a wireless LAN. In the initial state, the digital camera 100 has no setting of various parameters, and all have default values. Therefore, it is necessary to set various parameters for the digital camera 100 in the initial state by the parameter setting process described below.

  It is assumed that the digital camera 100 is in an initial state before the parameter setting process is started. Further, it is assumed that the digital camera 100 displays a screen such as the first camera screen 401 shown in FIG. The first camera screen 401 may be any screen, for example, indicating that the digital camera 100 is not connected for communication.

  First, in step S301, the user uses the first operation unit 105 (for example, the mode switching button 105b) of the digital camera 100 to input a wireless connection start instruction (for example, press and hold the mode switching button 105b). The first control unit 101 of the digital camera 100 receives a wireless connection start instruction by detecting a wireless connection start instruction via the first operation unit 105. When the first control unit 101 receives an instruction to start wireless connection, the first control unit 101 starts processing for wireless LAN connection (that is, processing after step S302). For example, Wi-Fi (registered trademark) can be adopted as a wireless LAN standard.

  Next, in step S302, the first control unit 101 of the digital camera 100 prepares to start the simple AP. More specifically, the 1st control part 101 acquires a wireless LAN parameter, before starting simple AP and starting transmission of a beacon. In step S302, the first control unit 101 acquires at least an SSID that is a network identifier and an encryption key as wireless LAN parameters. Since the digital camera 100 is in an initial state in step S302, the first control unit 101 acquires a default one as a wireless LAN parameter.

The SSID may be generated by the first control unit 101 based on device information recorded in advance in the nonvolatile memory or based on this device information. The device information is, for example, a device name, individual identification information (GUID: Globally Unique Identifier, UUID: Universally Unique Identifier, or the like).
Further, the first control unit 101 may use a value that is randomly determined by the first control unit 101 every time step S302 is executed as the encryption key. The encryption key may be generated by the first control unit 101 repeating the encryption calculation using the random number generated by the first control unit 101 as a passphrase.

  Next, in step S303, the first control unit 101 of the digital camera 100 activates a simple AP using the SSID and encryption key acquired in step S302 to form a wireless LAN network. Then, the first control unit 101 displays the second camera screen 402 shown in FIG. 4B on the first display unit 106. On the second camera screen 402, the wireless LAN parameters acquired in step S302 are displayed. More specifically, the second camera screen 402 displays an SSID and an encryption key as wireless LAN parameters. The process of forming a wireless LAN network is an example of processing by the forming unit.

Next, in step S304, the first control unit 101 of the digital camera 100 starts a DHCP (Dynamic Host Configuration Protocol) server. When the DHCP server is activated, the first control unit 101 prepares to allocate an IP address to a device that has joined the wireless LAN network formed by the simple AP of the digital camera 100.
Next, in step S305, the first control unit 101 of the digital camera 100 starts searching for devices. The first control unit 101 uses a discovery protocol for device search. The first control unit 101 can use, for example, SSDP (Single Service Discovery Protocol) or Malicast DNS as a discovery protocol. The second control unit 201 of the smart device 200 receives the discovery protocol packet via the second communication unit 211 and acquires the SSID of the wireless LAN network formed by the digital camera 100.

  Next, in step S306, the user uses the second operation unit 205 of the smart device 200 to input a wireless LAN setting start instruction from the OS menu. The second control unit 201 of the smart device 200 detects a wireless LAN setting start instruction via the second operation unit 205 and receives the wireless LAN setting start instruction. When the second control unit 201 receives a wireless LAN setting start instruction, the second control unit 201 displays a first device screen 501 illustrated in FIG. 5A on the second display unit 206. The first device screen 501 is a screen that displays a list of SSIDs. On the first device screen 501, the SSID acquired by the smart device 200 from the digital camera 100 in step S305 is displayed.

Next, in step S307, the user selects the SSID of the wireless LAN network formed by the digital camera 100 from the list of SSIDs on the first device screen 501 displayed on the second display unit 206 in step S305. The second control unit 201 of the smart device 200 receives an instruction to select a wireless LAN network via the second operation unit 205, and acquires the SSID selected by the user.
When the wireless LAN network selected by the user is secured, the second control unit 201 displays a second device screen 502 shown in FIG. 5B on the second display unit 206. The second device screen 502 is a screen for inputting the encryption key of the wireless LAN network selected by the user. At this time, the first display unit 106 of the digital camera 100 displays the second camera screen 402 including the wireless LAN parameters of the wireless LAN network formed by the digital camera 100. Therefore, the user operates the second operation unit 205 of the smart device 200 while looking at the SSID and encryption key of the second camera screen 402 displayed on the first display unit 106 of the digital camera 100, and sets the SSID. You can select and enter an encryption key. Then, the second control unit 201 acquires the SSID selected by the user and the encryption key input by the user via the second operation unit 205. The encryption key is also called a password.

  Next, in step S <b> 308, the second control unit 201 of the smart device 200 participates in the wireless LAN network formed by the digital camera 100. More specifically, the second control unit 201 transmits, for example, a notification of participation in the wireless LAN network formed by the digital camera 100 to the digital camera 100 via the second communication unit 211. The first control unit 101 of the digital camera 100 receives a participation notification via the first communication unit 111.

Next, in step S <b> 309, the DHCP server of the digital camera 100 transmits a packet for setting the IP address of the smart device 200 to the smart device 200 via the first communication unit 111. The second control unit 201 of the smart device 200 receives this packet via the second communication unit 211 and sets the IP address of the smart device 200 based on the received packet.
Through the processing from step S301 to step S309, communication connection between the digital camera 100 and the smart device 200 is established at the network level. Thereafter, since no other information processing apparatus needs to participate in the wireless LAN network formed by the digital camera 100, the first control unit 101 displays the third camera screen 403 shown in FIG. May be displayed. The third camera screen 403 is a screen indicating that communication connection between the digital camera 100 and the smart device 200 has been established at the network level, and displays the SSID of the wireless LAN network formed by the digital camera 100. .

Through the processing after step S310, communication connection between the digital camera 100 and the smart device 200 is established at the application level.
In step S <b> 310, the second control unit 201 of the smart device 200 displays the third device screen 503 illustrated in FIG. 5C on the second display unit 206. The third device screen 503 is a screen for accepting an instruction to start an application stored in the second nonvolatile memory 203 from the user. The user uses the second operation unit 205 to select, for example, an icon and input an application activation instruction. The second control unit 201 receives an application activation instruction via the second operation unit 205 and activates the application stored in the second nonvolatile memory 203. In the example of FIG. 3, it is assumed that the second control unit 201 has activated a camera operation application capable of setting the digital camera 100 and acquiring an image from the digital camera 100.

  Next, in step S <b> 311, the camera operation application executed by the second control unit 201 of the smart device 200 broadcasts an advertisement notification in the participating wireless LAN network via the second communication unit 211. Through this broadcast, the camera operation application notifies the digital camera 100 of the presence of itself. The first control unit 101 of the digital camera 100 receives an advertisement notification from the smart device 200 via the first communication unit 111. Note that the second control unit 201 uses a discovery protocol for advertisement notification. As a discovery protocol, for example, SSDP or Maltic DNS can be used.

Next, in step S312, the first control unit 101 of the digital camera 100 selects one of the advertised external devices. In step S312, since a parameter (connectable device information to be described later) representing an external device to be connected is not set in the digital camera 100, the first control unit 101 is a smart device that is a transmission source of an advertisement notification received first. Select 200.
A plurality of external devices can participate in the wireless LAN network formed by the digital camera 100. That is, one-to-many connection is possible at the network level. Therefore, the digital camera 100 may receive an advertisement notification from a plurality of external devices. Therefore, the first control unit 101 may prompt the user to select which external device to establish a communication connection at the application level in step S312.

Next, in step S313, the first control unit 101 of the digital camera 100 starts communication connection processing with the smart device 200 that is the external device selected in step S312. More specifically, the first control unit 101 transmits a communication connection start notification to the smart device 200 via the first communication unit 111. The second control unit 201 receives a communication connection start notification via the second communication unit 211.
Next, in step S <b> 314, the second control unit 201 of the smart device 200 transmits a connection permission notification to the digital camera 100 via the second communication unit 211. In the example of FIG. 3, the connection availability notification is a notification indicating that communication connection is performed. The first control unit 101 of the digital camera 100 receives a connection permission notification via the first communication unit 111.

  Next, in step S315, the application level communication connection between the digital camera 100 and the smart device 200 is completed. When the first control unit 101 of the digital camera 100 detects that the communication connection with the smart device 200 is completed, the first control unit 101 displays a fourth camera screen 404 illustrated in FIG. 4D on the first display unit 106. When the second control unit 201 of the smart device 200 detects that the communication connection with the digital camera 100 has been completed, the second control unit 201 displays a fourth device screen 504 illustrated in FIG. 5D on the second display unit 206. . The fourth camera screen 404 and the fourth device screen 504 indicate that the application level communication connection between the digital camera 100 and the smart device 200 has been completed. The fourth device screen 504 is a menu screen for a camera operation application.

Next, in step S <b> 316, the second control unit 201 of the smart device 200 receives an operation for setting the digital camera 100 on the fourth device screen 504 (for example, a touch of “setting a camera”). Next, the second control unit 201 transmits a parameter acquisition request to the digital camera 100 via the second communication unit 211.
When receiving the parameter acquisition request, the first control unit 101 of the digital camera 100 transmits various parameters to the smart device 200 via the first communication unit 111. The various parameters here include, for example, wireless LAN parameters including SSID and password.

The second control unit 201 of the smart device 200 receives various parameters from the digital camera 100 and acquires wireless LAN parameters. Next, the second control unit 201 displays a fifth device screen 505 illustrated in FIG. 5E on the second display unit 206. The fifth device screen 505 is a setting screen for setting various parameters of the digital camera 100 from the smart device 200. The fifth device screen 505 may display various parameters acquired by the smart device 200 from the digital camera 100 as initial values.
The communication protocol used in step S316 may be HTTP (Hyper Text Transfer Protocol) or PTP-IP.

  Next, in step S317, the user inputs various parameters of the digital camera 100 using the second operation unit 205 while referring to the fifth device screen 505 displayed on the second display unit 206. The second control unit 201 of the smart device 200 receives various parameters of the digital camera 100 via the second operation unit 205.

In step S317, the parameters received by the second control unit 201 include, for example, a wireless LAN parameter, a still image shooting parameter, and a moving image shooting parameter.
The wireless LAN parameters include the first parameter to the seventh parameter.
