FIG. 1 is a block diagram showing an example of a communication system in which a communication device according to the first embodiment of the present invention is used.

In the illustrated communication system, an image pickup device and a mobile terminal device having a wireless communication function are used as communication devices. The image pickup device is, for example, a digital camera (hereinafter, simply referred to as a camera) which is a communication device, and the mobile terminal device is, for example, a smartphone which is another communication device. The other communication device may be an information processing device such as a portable media player, a so-called tablet device, or a personal computer.

The camera A100 has a control unit A101, and the control unit A101 controls the entire camera A100 according to a control program. Instead of controlling the entire camera A100 by the control unit A101, the processing may be shared by a plurality of hardware to control the entire camera A100.

The image pickup unit A102 includes, for example, an optical lens unit having aperture, zoom, and focus functions, and outputs an electric signal (analog signal) corresponding to the optical image formed by the optical lens unit to output the analog signal. It has an image pickup element that converts into a digital signal by A / D conversion.

Here, as the image pickup device, for example, CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charge Coupled Device Image Sensor) is used. The image pickup unit A102 outputs an electric signal according to the optical image under the control of the control unit A101, performs noise reduction processing on the electric signal, and then outputs a digital signal as image data.

Here, the image data is recorded on the recording medium A110 according to the DCF (Design rule for Camera File system) standard.

The non-volatile memory A103 is a memory that can be electrically erased and recorded, and stores a control program or the like executed by the control unit A101. The working memory A104 is used as a buffer memory for temporarily recording image data obtained as a result of imaging by the imaging unit A102, and is also used as an image display memory and a working area of the control unit A101.

The operation unit A105 is used to receive an instruction from the user from the user. The operation unit A105 includes, for example, a power button for turning on or off the power of the camera A100, a release switch for instructing an image pickup, and a reproduction button for instructing reproduction of image data. The touch panel formed on the display unit A106, which will be described later, is also included in the operation unit A105.

On the display unit A106, a live view is displayed in the imaging preparation stage for capturing a still image, and a still image obtained as a result of imaging is displayed. Further, characters for interactive operation are displayed on the display unit A106.

The power management unit A107 is a unit for supplying electric power to the camera A100. The power management unit A107 can supply power to the entire camera A100, and can supply power only to the sub-control unit A120 and the power-saving wireless communication unit A112, which will be described later.

In the following description, the state in which power is supplied to the entire camera A100 is referred to as a power ON state (second mode), and power is supplied only to the sub-control unit A120 and the power-saving wireless communication unit A112. The state is called a standby state (first mode). Further, a state in which the power supply of the entire camera A100 is cut off is called a power-off state. In the standby state, the power consumption of the camera A100 can be kept extremely low.

Image data obtained as a result of imaging by the imaging unit A102 is recorded on the recording medium A110. Although the recording medium A110 is removable from the camera A100, it may be built into the camera A100.

The wireless communication unit A111 is, for example, an interface for performing wireless LAN communication (first communication protocol) conforming to the IEEE802.11 standard. Through this wireless LAN communication, the camera A100 can perform wireless communication with a surrounding wireless access point (hereinafter referred to as an access point or AP) C100. Further, the camera A100 can transmit and receive data to and from a server device (external device: not shown) connected to the cloud network D100 via the access point C100 by a higher-level protocol such as TCP / IP.

The power-saving wireless communication unit A112 has, for example, an antenna for wireless communication, a modulation / demodulation circuit for processing a wireless signal, and a communication controller. The power-saving wireless communication unit A112 outputs a wireless signal from the antenna, demodulates the wireless signal received by the antenna, and performs short-range wireless communication according to the standard of IEEE802.15 (so-called Bluetooth (registered trademark)).

In the illustrated example, Bluetooth communication (second communication protocol) uses version 4.0 of Bluetooth Low Energy, which has low power consumption (second power consumption). This Bluetooth communication has a narrow communicable range (that is, a short communicable distance) as compared with wireless LAN communication. Further, the communication speed of Bluetooth communication is slower than that of wireless LAN communication. On the other hand, Bluetooth communication has lower power consumption than wireless LAN communication. Assuming that the power consumption by wireless LAN communication is the first power consumption, the first power consumption> the second power consumption.

The sub-control unit A120 controls the communication by the power-saving wireless communication unit A112 and the control of the camera A100 in the standby state. The sub-control unit A120 has a built-in working memory and non-volatile memory necessary for its operation, whereby the sub-control unit A120 is in a standby state in which power is not supplied to the non-volatile memory A103 and the working memory A104. Can also work.

Further, the sub-control unit A120 enables communication with the smartphone B100, which will be described later, by using the power-saving wireless communication unit A112 even when the camera A100 is in the standby state. Further, the sub-control unit A120 returns the camera A100 from the standby state to the power ON state (second mode) via the power management unit A107 according to the communication content of the power saving wireless communication unit A112. The blocks shown in FIG. 1 are connected to each other by the internal bus A130.

The smartphone B100 has a control unit B101, and the control unit B101 controls the entire smartphone B100 according to a control program. Instead of the control unit B101 controlling the entire smartphone B100, a plurality of hardware may share the processing to control the entire smartphone B100.

The illustrated smartphone B100 has an image pickup unit B101, and the image pickup unit B101 is the same as the image pickup unit A101 described above, and the image data obtained by the image pickup unit B101 is recorded on the recording medium B110 according to the DCF standard.

The non-volatile memory B103 is the same memory as the non-volatile memory A103, and the non-volatile memory B103 stores a control program or the like executed by the control unit B101. The working memory B104 is the same as the working memory A104, and is used as a buffer memory, an image display memory, and a working area of the control unit B101.

The operation unit B105 is used to receive an instruction from the user from the user. The operation unit B105 includes, for example, a power button for turning on or off the power of the smartphone B100, and an operation button for instructing a screen transition. The operation unit B105 also includes a touch panel formed on the display unit B106, which will be described later.

A still image obtained as a result of shooting is displayed on the display unit B106. Further, a GUI (Graphical User Interface) for performing an interactive operation is displayed on the display unit B106. The display unit B106 does not necessarily have to be provided in the smartphone B100, and the smartphone B100 may have at least a display control function for controlling the display contents.

The power management unit B107 is a unit for supplying electric power to the smartphone B100. Although the above-mentioned recording medium B110 is removable from the smartphone B100, it may be built into the smartphone B100. Further, the wireless communication unit B111 is the same as the wireless communication unit A111, and the power saving wireless communication unit B112 is the same as the wireless communication unit A112.

The public radio communication unit B113 is an interface for communicating with the public network F100 via the base station E100. The public radio communication unit B113 has an antenna for radio communication, a modulation / demodulation circuit for processing the radio signal, and a communication controller. In the illustrated example, the public radio communication unit B113 performs public radio communication according to a standard such as W-CDMA (UMTS) or LTE (Long Term Evolution).

The above blocks are connected to each other by the internal bus B130. Further, in the example shown in FIG. 1, an example in which the camera A100 and the smartphone B100 communicate one-to-one is shown, but the camera A100 can perform one-to-many communication with a plurality of smartphones.

<Pairing operation>
Subsequently, the initial setting performed by the camera A100 to enable the smartphone B100 and the digital camera A100 shown in FIG. 1 to communicate with each other by the power-saving wireless communication units B112 and A112 will be described.

FIG. 2 is a flowchart for explaining the initial setting operation of the camera shown in FIG. The process related to the illustrated flowchart is performed under the control of the control unit A101.

Prior to the process shown in FIG. 2, the power of the camera A100 is turned on, and the user can change the setting of the camera A100 by the operation unit A102. Then, in making this setting, communication by BLE is performed between the smartphone B100 and the camera A100. At that time, the smartphone B100 behaves as the BLE Central and the digital camera A100 behaves as the BLE Peripheral. ..

In step S201, the control unit A101 displays the setting menu screen on the display unit A106 and waits until the user selects the pairing setting menu by the operation unit A105. The setting menu screen will be described later.

In step S202, the control unit A101 advises the pairing information for starting the pairing by the power saving wireless communication unit A112. For example, the control unit A101 performs an update of the AP Find service for pairing according to the GATT profile of BLE.

In the AP Find service, the Central ID characteristic for writing ID information (connection information) for the device to be connected (hereinafter referred to as Central) for which initial setting is requested to uniquely identify Central, and Status indicating the progress of initial setting. The characteristics and are included. In step S202, Advertise is performed in a state where a NULL value is set for the CentralID characteristic and the character string "Initializing" is set for the Status characteristic. This BLE Advance is automatically repeated by the power saving wireless communication unit A112 until the control unit A101 explicitly instructs the stop. In addition, the AP Find service also includes an SSID characteristic in which Central writes the SSID of the access point C100 that has received the beacon, as will be described later.

In step S203, the control unit A101 determines whether or not there is a write request from the Central to the Central ID characteristic to the Advanced. This request corresponds to the request made by the smartphone B100, as will be described later. If the control unit A101 determines that there is no write request, the process of step S203 is repeated until the request is received. When the control unit A101 determines that there is a write request, the process proceeds to the process of step S204.

In step S204, the control unit A101 determines whether or not the Central that requested the write has already been BLE paired. If the control unit A101 determines that the pairing has already been completed, the process proceeds to step S209 described later.

On the other hand, if the control unit A101 determines that the pairing has not been performed yet, the process proceeds to step S205. In step S205, under the control of the control unit A101, the power saving wireless communication unit A112 transmits a pairing request to the Central. Then, in step S206, the control unit A101 displays the PIN confirmation screen on the display unit A106. Here, a different 6-digit numerical value is generated for each pairing request and used as a PIN number.

Subsequently, in step S207, the control unit A101 determines whether or not the power saving wireless communication unit A112 has received the PIN number from the Central. The reception of this PIN number corresponds to the transmission of the smartphone 101. If the control unit A101 determines that the PIN number is not received, the process of step S207 is repeated until the PIN number is received.

If the control unit A101 determines that the PIN number has been received, the process proceeds to step S208. In step S208, the control unit A101 determines whether or not the received PIN number matches the PIN number generated in step S206. If the control unit A101 determines that the PIN numbers do not match, the control unit A101 returns to the process of step S205 and transmits the pairing request again. On the other hand, if the control unit A101 determines that the PIN numbers match, the process proceeds to step S209.

In step S209, the control unit A101 stores the CentralID value of the AP Find service in the non-volatile memory A103. Here, the control unit A101 also stores the CentralID value in the non-volatile memory built in the sub-control unit A120.

Subsequently, in step S210, the control unit A101 notifies the Central that the initial setting is completed by the power saving wireless communication unit A112. For example, the control unit A101 sets the value of the Status characteristic of the AP Find service in the Advantage as "Service" so that the Central that has received the Advantage can know that the initial setting has been completed.

Next, in step S211 the control unit A101 displays the pairing completion screen on the display unit A106. The pairing completion screen will be described later. Then, in step S212, the control unit A101 stops the BLE AP Find service Advantage started in step S202 by the power saving wireless communication unit A112. After that, the control unit A101 ends the initial setting operation. As a result, Central and Peripheral are connected to each other.

When both the Central and the Peripheral shift to the connected state, the Central and the Peripheral mutually send and receive packets at regular intervals. Then, as long as the communication is maintained, it is considered that the Central and the Peripheral are connected to each other. If the communication from the other party does not arrive, the connection status is canceled.

FIG. 3 is a diagram for explaining the selection of the pairing setting menu performed by the camera shown in FIG. 1. 3A is a diagram showing a setting top screen, and FIG. 3B is a diagram showing a connection setting screen. Further, FIG. 3C is a diagram showing a pairing screen, and FIG. 3D is a diagram showing a PIN confirmation screen. Further, FIG. 3 (e) is a diagram showing a pairing completion screen.

Now, when selecting the pairing setting menu in step S201, the user operates the operation unit A105 to display the setting top screen shown in FIG. 3A on the display unit A106. When the user selects the connection setting menu item 302 with the smartphone B100 from the setting item list 301 on this setting top screen, the control unit A101 displays the connection setting screen shown in FIG. 3B on the display unit A106.

When the user selects the pairing setting menu 312 with the smartphone B100 from the setting item list 311 on the connection setting screen, the control unit A101 displays the pairing screen shown in FIG. 3C on the display unit A106. Then, the user selects the additional menu item 321 of the new smartphone on the pairing screen. As a result, the pairing setting menu is selected in the camera A100.

FIG. 3D shows a PIN confirmation screen displayed on the display unit A106 by the process of step S206 described with reference to FIG. The user does not need to operate the camera A100 with respect to the PIN confirmation screen. By inputting the PIN code 331 displayed on the PIN confirmation screen into the smartphone B100, the pairing is executed and the process proceeds to the process of step S207 shown in FIG.

FIG. 3E shows a pairing completion screen displayed on the display unit A106 by the process of step S212 described with reference to FIG. When the user selects the OK button 341 on the pairing completion screen, the control unit A101 ends the process of step S212.

Next, the initial setting performed by the smartphone B100 to enable the smartphone B100 and the digital camera A100 shown in FIG. 1 to communicate with each other by the power-saving wireless communication units B112 and A112 will be described.

FIG. 4 is a flowchart for explaining the initial setting operation of the smartphone shown in FIG. The process related to the illustrated flowchart is performed under the control of the control unit B101.

Prior to the start of the process according to the illustrated flowchart, it is assumed that the user has started an application for communicating with the camera A100 on the smartphone B100. In performing the initial setting, communication by BLE is performed between the smartphone B100 and the camera A100. At this time, the smartphone B100 behaves as the BLE Central and the camera A100 behaves as the BLE Peripheral.

In step S401, the control unit B101 displays the setting menu screen on the display unit B106 and waits for the user to select the pairing setting menu. The setting menu screen will be described later.

When the process proceeds to step S402 by the user operation on the setting menu screen, the control unit B101 displays the pairing execution screen on the display unit B106 in step S402. Then, in step S403, the control unit B101 determines whether or not the Advantage has been received from the BLE Peripheral by the power saving wireless communication unit B112. The control unit B101 waits until the Advantage is received.

Upon receiving the Advantage, in step S404, the control unit B101 determines whether or not the received Advantage includes the AP Find service. When the control unit B101 determines that the Advanced does not include the AP Find service, the control unit B101 returns to the process of step S403.

When the control unit B101 determines that the received Advantage includes the AP Find service, the control unit B101 proceeds to the process of step S405. The Update of the AP Find service corresponds to the Advantage transmitted by the LeCamera A100 in step S202 described with reference to FIG.

In step S405, the control unit B101 generates a unique ID that can identify the smartphone B100, and makes a write request to the CentralID characteristic of the AP Find service. As described in connection with FIG. 2, the CentralID characteristic of the AP Find service is set so that an authentication process between devices called pairing is required in BLE when writing the value.

Subsequently, in step S406, the control unit B101 determines whether or not a pairing request has been received from Central. This pairing request corresponds to the pairing request transmitted in step S205 described with reference to FIG. 2, when the power-saving wireless communication unit B112 has not yet been BLE paired with the Peripheral whose Central ID characteristic has been adapted. Only send.

If the control unit B101 determines that the pairing request is not received, that is, it is determined that the pairing has already been completed and the value can be written to the CentralID characteristic, the process proceeds to step S409. On the other hand, if the control unit B101 determines that the pairing request has been received, the process proceeds to step S407.

In step S407, the control unit B101 displays the PIN input screen on the display unit 104. The PIN input screen will be described later. When the user inputs the PIN number on the PIN input screen, in step S408, the control unit B101 transmits the PIN number to the peripheral by the power saving wireless communication unit B112. The camera A100 receives the PIN number and determines whether or not the PIN numbers match as described above.

Next, in step S409, the control unit B101 determines whether or not the pairing completion notification has been received. For example, the control unit B101 determines whether or not the value of the Status characteristic of the AP Find service has become "Success". This determination corresponds to the process of step S210 described with reference to FIG. 2, and the camera A100 gives a pairing completion notification when the received PIN number matches the PIN number generated by the camera A100.

If the control unit B101 determines that the pairing completion notification is not received, the control unit B101 determines that the input PIN number is incorrect and returns to the process of step S406. On the other hand, if the control unit B101 determines that the pairing completion notification has been received, the process proceeds to step S410. In step S410, the control unit B101 displays the pairing completion screen on the display unit 104. The pairing completion screen will be described later. Then, when the pairing completion screen is closed, the control unit B101 ends the initial setting.

FIG. 5 is a diagram for explaining selection of the pairing setting menu performed by the smartphone shown in FIG. 1. 5 (a) is a diagram showing a setting top screen, and FIG. 5 (b) is a diagram showing a screen during pairing execution. Further, FIG. 5C is a diagram showing a PIN input screen, and FIG. 5D is a diagram showing a pairing completion screen.

Now, when selecting the pairing setting menu in step S401, the user operates the operation unit B105 to display the setting top screen shown in FIG. 5A on the display unit B106. On this setting top screen, an operation button 501 for connecting to a paired camera and an operation button 502 for pairing with a new camera, that is, a pairing button are displayed. When the user selects the pairing button 502 with the new camera from the operation buttons, the control unit B101 displays the pairing execution screen on the display unit B106 in FIG. 5B.

A message 511 prompting the camera A100 to be activated in the pairing mode is displayed on the pairing execution screen, but the user does not need to operate the smartphone B100 on the pairing execution screen, and is instructed. It is necessary to start the camera A100 in the pairing mode according to the above. This operation has been described in step S201 shown in FIG. Then, as described above, the pairing process is started, and the process proceeds to step S403.

FIG. 5C shows a PIN input screen displayed on the display unit B106 in step S407 shown in FIG. According to the message 521, the user reads the PIN code 331 (see FIG. 3D) displayed on the display unit A106 of the camera A100 and inputs it to the PIN input area 522 of the PIN input screen. After that, the user selects the pairing execution button 523. By this operation, the process of step S407 shown in FIG. 4 is completed, and the process proceeds to step S408.

FIG. 5D shows a pairing completion screen displayed on the display unit B106 in the process of step S410 shown in FIG. The wording 531 indicating that pairing has been performed is displayed on the pairing completion screen, and when the user selects the OK button 532 on the pairing completion screen, the control unit B101 processes the step S410 shown in FIG. To finish.

In the camera A100, when the power button is turned off, it is possible to switch between the power off state and the standby state of the camera A100 depending on the setting.

FIG. 6 is a diagram for explaining the state setting of the camera when the power button of the camera shown in FIG. 1 is turned off. FIG. 6A is a diagram showing a setting top screen, and FIG. 6B is a diagram showing a connection setting screen. Further, FIG. 6C is a diagram showing a start setting screen.

Now, when the user operates the operation unit A105 when the power button of the camera A100 is turned off, the control unit A101 displays the setting top screen shown in FIG. 6A on the display unit A106. When the user selects the connection setting menu item 602 with the smartphone B101 from the setting item list 601 on the setting top screen, the control unit A101 displays the connection setting screen shown in FIG. 6B on the display unit A106.

When the user selects the activation setting menu 612 from the smartphone from the setting item list 611 on the connection setting screen, the control unit A101 displays the activation setting screen of the smartphone B100 shown in FIG. 6C on the display unit A106. On the activation setting screen, two options, a valid menu 621 and an invalid menu 622, are displayed.

Now, when the user selects the valid menu 621, the control unit A101 puts the digital camera A100 in the standby state when the power button is turned off. On the other hand, when the user selects the invalid menu 622, the control unit A101 turns off the power of the digital camera A100 when the power button is turned off.

<Overview of the system>
FIG. 7 is a sequence diagram for explaining the flow of processing from access point detection to image transmission in the communication system shown in FIG.

In FIG. 7, the broken line arrow indicates that the communication is by BLE, and the thick solid line arrow indicates that the communication is by wireless LAN. Further, it is assumed that the camera A100 and the smartphone B100 have been paired by BLE in advance. Further, it is assumed that the SSID and password information of the access point C100 desired to be connected are input in advance from the operation unit A105 to the camera A100 and stored in the non-volatile memory A103.

Here, it is assumed that the SSID of the access point C100 desired to be connected is notified in advance from the camera A100 to the power saving wireless communication unit B112 in the smartphone B100 and stored in the non-volatile memory B103. Then, when starting the illustrated sequence, it is assumed that the camera A100 is in the standby state.

In step S710, the smartphone B100 receives a beacon packet (also simply referred to as a beacon) broadcast by wireless LAN communication from the access point C100. Here, the access point C100 adds access point information (for example, SSID and communication rate setting) to the beacon packet and transmits it.

Upon receiving the beacon packet, in step S711, the smartphone B100 determines whether the SSID included in the received beacon packet is the SSID of the access point C100 desired to be connected, which is previously notified by the camera A100 and stored in the non-volatile memory B103. To match. If the SSID of the beacon packet is that of the access point C100 desired to be connected, in step S712, the smartphone B100 transmits an access point detection notification to the camera A100 by BLE. At this time, the smartphone B100 adds the detected access point information of the access point C100 and transmits it to the camera A100.

Before transmitting the access point detection notification (access point detection signal), the smartphone B100 displays an inquiry screen inquiring whether or not to transmit the access point detection notification to the display unit B106. Then, the smartphone B100 may wait for an instruction by the user and transmit the access point detection notification to the camera A100 only when the transmission instruction is received.

Upon receiving the access point detection notification, in step S713, the sub-control unit A120 controls the power supply management unit A107 in the camera A100 to switch the camera A100 from the standby state to the power-on state. Further, the sub-control unit A120 enables the wireless LAN communication function of the wireless communication unit A111.

In step S714, the camera A100 receives the beacon packet broadcast by wireless LAN communication from the access point C100. Then, in step S715, the camera A100 establishes a wireless LAN connection with the access point C100 based on the access point information included in the received beacon packet and the password information stored in the non-volatile memory A103 in advance.

Subsequently, in step S716, the camera A100 transmits all the unuploaded images to the desired PC on the cloud network D100 via the access point C100 by wireless LAN. When the image transmission is completed, in step S717, the communication between the camera A100 and the access point C100 by wireless LAN is disconnected. When the digital camera A100 disconnects the communication by the wireless LAN, the digital camera A100 shifts to the standby state in step S718.

<Operation of each device>
FIG. 8 is a flowchart for explaining the operation of the camera A100 when transmitting the image shown in FIG. 7. The processing related to the illustrated flowchart is performed by the control unit A101 and the sub-control unit A120.

The process according to the illustrated flowchart is started by receiving the standby start instruction of the access point detection notification from the smartphone B100 after the SSID of the access point C100 desired to be connected is registered by the user by the touch panel operation in the operation unit A105. .. During standby, the camera A100 is in the standby state.

In step S810, the sub-control unit A120 determines whether or not one or more Central ID information (network identifier) of the paired BLE device is stored in the built-in non-volatile memory. If the sub-control unit A120 determines that the Central ID information does not exist, the sub-control unit A120 performs the process of step S809 described later, and then ends the process. On the other hand, if the Central ID information is present, the sub-control unit A120 proceeds to the process of step S820.

In step S820, the sub-control unit A120 advises the information for starting pairing by the power-saving wireless communication unit A112. For example, the sub-control unit A120 performs avertise of the AP Find service for performing pairing according to the GATT profile of BLE. The AP Find service includes a Central ID characteristic for writing ID information for a device to be connected (hereinafter referred to as Central) for which initial setting is requested to uniquely identify the Central, and a Status characteristic for indicating the progress of the initial setting. ing.

In step S202 described with reference to FIG. 2, the Null value is set for the CentralID characteristic, and the character string "Initializing" is set for the Status characteristic, and the Advertise is performed. This BLE advice is repeatedly performed by the power saving wireless communication unit A112 until there is an explicit stop instruction. In addition, the AP Find service includes an SSID characteristic in which Central writes the SSID of the access point C100 that has received the beacon packet.

In step S811, the sub-control unit A120 determines whether or not there is a write request for the SSID characteristic of the AP Find service to the power-saving wireless communication unit A112. If there is no write request, the sub-control unit A120 repeats the process of step S811 until the write request is received. On the other hand, when the write request is received, the sub-control unit A120 proceeds to the process of step S812. The write request received in step S811 corresponds to the write request transmitted in step S911 shown in FIG. 9 described later.

In step S812, the sub-control unit A120 determines whether or not the write request received in step S811 is transmitted from the paired BLE device. Here, the sub-control unit A120 is set by whether or not the Central ID of the Central that made the write request is stored in the non-volatile memory built in the sub-control unit A120, that is, by the pairing setting described with reference to FIG. It is determined whether or not it is non-volatile.

When the sub-control unit A120 determines that the write request is from the paired BLE device, the value of the SSID characteristic of the AP Find service is stored in the built-in non-volatile memory, and then the process proceeds to step S802. On the other hand, if the sub-control unit A120 determines that the write request is from a BLE device that has not been paired, the process returns to the process of step S811.

In step S802, the sub-control unit A120 turns on the camera A100 by the power supply management unit A107. As a result, the wireless communication unit A111 can receive the beacon packet from the access point C100. The process of step S802 corresponds to the process of step S713 shown in FIG. 7.

Subsequently, in step S803, the control unit A101 determines whether or not there are a predetermined number or more of unuploaded images in the recording medium A110. When the control unit A101 determines that there are a predetermined number or more of unuploaded images, the process proceeds to step S804.

On the other hand, if the control unit A120 determines that the number of unuploaded images is less than a predetermined number, the process proceeds to step S821. In addition, in order to determine the unuploaded image, the control unit A101 embeds a flag indicating unuploaded in the extended information area of the image data obtained by shooting, and changes the flag to uploaded at the time of uploading. You may. Further, the predetermined number of sheets may be one, and further, the user may set the number by the operation unit A105.

Next, in step S804, the control unit A101 determines whether or not the remaining amount of the battery (battery power supply) is equal to or greater than the predetermined remaining amount by the power supply management unit A107. When the control unit A101 determines that the remaining battery level is equal to or higher than the predetermined remaining amount, the process proceeds to step S805. On the other hand, if the control unit A101 determines that the remaining battery level is less than the predetermined remaining amount, the process proceeds to step S821.

In step S805, the control unit A101 receives the beacon packet broadcast by the wireless communication unit A111 from the access point C100 by wireless LAN communication. The process of step S805 corresponds to the process of step S714 shown in FIG. 7. If the beacon packet cannot be received, the control unit A101 may set the camera A100 in the standby state by the power management unit A107.

Subsequently, in step S806, the control unit A101 establishes a wireless LAN connection with the access point C100 based on the access point information included in the received beacon packet and the password information previously stored in the non-volatile memory A103. The process of step S806 corresponds to the process of step S715 shown in FIG. 7.

Next, in step S807, the control unit A101 transmits all the unuploaded images to the access point C100 by the wireless communication unit A111. The process of step S807 corresponds to the process of step S716 shown in FIG. 7.

In step S808, the control unit A101 disconnects the communication with the access point C100 by the wireless communication unit A111. The process of step S808 corresponds to the process of step S717 shown in FIG. 7.

Next, in step S821, the control unit A101 stops the BLE Advance that started in step S820. Then, in step S809, the control unit A101 turns off the power supply by the power supply management unit A107 and puts the camera A100 in the standby state. The process of step S809 corresponds to the process of step S718 shown in FIG. If there is no unuploaded image or the remaining battery level is less than the predetermined remaining amount, the control unit A101 may turn off the power of the camera A100.

FIG. 9 is a flowchart for explaining the operation of the smartphone B100 when the image transmission shown in FIG. 7 is performed. The process related to the illustrated flowchart is performed by the control unit B101.

The process according to the flowchart shown in FIG. 9 is started when the control unit B101 receives an operation for starting beacon packet collation from the operation unit B105. For example, in response to a menu operation by the user, the BLE function and the wireless LAN function are effectively set for the OS (Operating System) installed in the smartphone B100, and an application program that performs processing related to the flowchart (hereinafter, simply an application). Also called) starts. As a result, the smartphone B100 is in a state of waiting for the reception of the beacon packet transmitted from the access point C100, and starts the process according to the flowchart shown in FIG.

It is assumed that the SSID of the access point C100 that the camera A100 wants to connect to is notified in advance from the camera A100 to the smartphone B100 via the power saving wireless communication unit B112 and stored in the non-volatile memory B103. Alternatively, the user may input the SSID of the access point C100 into the smartphone B100 by the operation unit B105.

In step S910, the control unit B101 determines whether or not one or more Peripheral ID information of the paired BLE device is stored in the non-volatile memory B103. When the control unit B101 determines that the Peripheral ID information does not exist, the control unit B101 ends the process. On the other hand, if the control unit B101 determines that the Peripheral ID information exists, the process proceeds to the process of step S901.

In step S901, the control unit B101 determines whether or not the SSID of the access point information included in the received beacon packet matches the SSID stored in the non-volatile memory B103. If the control unit B101 determines that the SSIDs match, the process proceeds to step S920. On the other hand, if the control unit B101 determines that the SSIDs do not match, the process proceeds to step S903. The process of step S901 corresponds to the process of step S711 shown in FIG. 7.

In step S920, the control unit B101 determines whether or not the Advantage has been received from the BLE Peripheral by the power saving wireless communication unit B112. When the control unit B101 determines that the Advantage has been received, the control unit B101 proceeds to the process of step S921. On the other hand, if the control unit B101 determines that the Advantage has not been received, the process of step S920 is repeated.

In step S921, the control unit B101 determines whether or not the Advantage received in step S920 includes the AP Find service. When the control unit B101 determines that the Advanced does not include the AP Find service, the control unit B101 returns to the process of step S920. On the other hand, when the control unit B101 determines that the Advanced service includes the AP Find service, the control unit B101 proceeds to the process of step S911. The Advanced of the AP Find service received here corresponds to the Advanced transmitted from the camera A100 in the process of step S820 shown in FIG.

In step S911, the control unit B101 notifies the camera A100 that the access point C100 desired to be connected has been detected by the power saving wireless communication unit B112. For example, the control unit B101 transmits an AP Find service for performing an access point detection notification by the GATT profile of BLE. The AP Find service includes an SSID characteristic indicating the SSID of the access point C100 that received the beacon in the process of step S901.

The SSID characteristic is set so that an authentication process between devices called pairing in BLE is required when writing the value. The access point detection notification transmitted by the process of step S911 corresponds to the access point detection notification received in step S811 shown in FIG. Further, the process of step S911 corresponds to the process of step S712 shown in FIG. 7.

Subsequently, in step S903, the control unit B101 determines whether or not the processing end instruction has been received from the operation unit B105 by the user. When the control unit B101 determines that the processing end instruction has been received, the control unit B101 ends the processing. On the other hand, if the control unit B101 determines that the process end instruction has not been received, the process returns to the process of step S901.

As described above, in the first embodiment of the present invention, the camera A100 in the power saving state with the wireless LAN disabled receives the BLE notification from the smartphone B100 in which the beacon of the access point C100 is detected. Then, the camera A100 enables wireless LAN and establishes wireless LAN communication with the access point C100. As a result, the camera A100 can automatically detect the access point C100 desired to be connected without consuming a power source such as a battery. Further, when the image transfer is completed, the camera A100 stops the BLE advertisement, so that the power consumption can be further reduced.

[Second Embodiment]
Subsequently, an example of a communication system including a communication device according to a second embodiment of the present invention will be described.

<Overview of the system>
In the first embodiment described above, the case where the camera A100 stops the BLE update when the image transfer is completed and the wireless LAN is disconnected has been described. On the other hand, in the second embodiment, a case will be described in which the camera A100 does not stop the BLE Advertise even if the image transfer is completed and the wireless LAN is disconnected.

Since the configuration of the communication system according to the second embodiment is the same as that of the communication system shown in FIG. 1, the description thereof will be omitted here. Further, it is assumed that the digital camera A100 and the smartphone B100 have been paired in advance.

In the second embodiment, in addition to the characteristics described in the first embodiment, the AP Find service has a detection state characteristic for setting the detection state of the access point C100 from the camera A100 to the smartphone B100. Shall be included. The detection state characteristics include "detection start" and "detection stop". When "Start detection" is set, the smartphone B100 starts detecting the access point C100. When "stop detection" is set, the smartphone B100 stops the detection of the access point C100.

The camera A100 notifies the smartphone B100 of the start of detection by setting the detection state characteristic to "start detection". On the other hand, the camera A100 notifies the smartphone B100 of the detection stop by setting the detection state characteristic to "detection stop". Then, at the time of pairing, the camera A100 performs Advantage of the AP Find service with the detection state characteristic as "detection start".

FIG. 10 is a sequence diagram for explaining a flow of processing from access point detection to image transmission in a communication system including a communication device according to a second embodiment of the present invention. In FIG. 10, the same steps as those shown in FIG. 7 are designated by the same reference numerals and the description thereof will be omitted.

In step S717, the camera A100 disconnects the wireless LAN, and then in step 1001, the camera A100 transmits a detection stop notification of the access point C100 to the smartphone B100 by BLE.

Upon receiving the detection stop notification from the camera A100, the smartphone B100 stops the transmission of the access point detection notification in step S1002. Subsequently, in step S1003, the camera A100 waits for the unuploaded image to be recorded on the recording medium A110 due to shooting by the user or the like.

When the unuploaded image is recorded on the recording medium A110, in step S1004, the camera A100 transmits a detection start notification of the access point C100 to the smartphone B100 by BLE. Then, upon receiving the detection start notification from the camera A100, the smartphone B100 starts transmitting the access point detection notification in step S1005.

<Operation of each device>
FIG. 11 is a flowchart for explaining the operation of the camera when transmitting an image in the communication system according to the second embodiment of the present invention. In the flowchart shown in FIG. 11, the same steps as those in the flowchart shown in FIG. 8 are designated by the same reference numerals and the description thereof will be omitted. Further, the processing according to the illustrated flowchart is performed under the control of the control unit A101 and the sub-control unit A120.

The process according to the flowchart shown in FIG. 11 is started when the power is turned off by the power switch provided in the operation unit A105. When the sub-control unit A120 determines that the Central ID information exists, in step S1101, the control unit A101 determines whether or not there are a predetermined number or more of unuploaded images in the recording medium A110. When the control unit A101 determines that there are a predetermined number or more of unuploaded images, the process proceeds to step S1102. On the other hand, if the control unit A101 determines that the number of unuploaded images is less than a predetermined number, the process proceeds to step S809.

In order to determine the number of unuploaded images, for example, the control unit A101 embeds a flag indicating unuploaded in the extended information area of the image at the time of shooting. Then, at the time of uploading, the control unit A101 may change the flag to uploaded. Further, the predetermined number of sheets may be one, and may be set by the user from the operation unit A105.

In step S1102, the control unit A101 transmits an access point C100 detection start instruction (detection request) to the smartphone B100 by the power saving wireless communication unit A112. For example, the control unit A101 transmits the detection state characteristic of the AP Find service according to the GATT profile of BLE. At this time, the detection state characteristic is transmitted as "detection start". The process of step S1102 corresponds to the process of step S1104 shown in FIG.

Subsequently, in step S1103, the control unit A101 puts the camera A100 in the standby state by the power management unit A107. After that, the control unit A101 performs the process of step S811 described above. After performing the process of step S808 described above, the control unit A101 transmits a detection stop instruction of the access point C100 to the smartphone B100 by the power saving wireless communication unit A112 in step S1104. For example, the control unit A101 transmits the detection state characteristic of the AP Find service according to the GATT profile of BLE. At this time, the detection state characteristic is transmitted as "detection stop". The process of step S1104 corresponds to the process of step S1001 shown in FIG. After performing the process of step S1104, the control unit A101 proceeds to the process of step S809.

FIG. 12 is a flowchart for explaining the operation of the smartphone B100 when image transmission is performed in the communication system according to the second embodiment of the present invention. In the flowchart shown in FIG. 12, the same steps as those in the flowchart shown in FIG. 9 are designated by the same reference numerals and the description thereof will be omitted. Further, the processing related to the illustrated flowchart is performed under the control of the control unit B101.

Did the control unit B101 receive the detection stop notification of the access point C100 desired to be connected from the camera A100 by the power saving wireless communication unit B112 in step S1201 after the beacon packet was not detected in step S901 or the process of step S911 was performed? Judge whether or not. For example, the control unit B101 receives the detection state characteristic of the AP Find service according to the GATT profile of BLE. At this time, if the detection state characteristic is "detection stop", the control unit B101 determines that the detection stop notification has been received. When the control unit B101 determines that the detection stop notification has been received, the process proceeds to step S1202. On the other hand, if the control unit B101 determines that the detection stop notification is not received, the process proceeds to step S903.

In step S1202, the control unit B101 determines whether or not the power saving wireless communication unit B112 has received the detection start notification of the access point C100 desired to be connected from the camera A100. For example, the control unit B101 receives the detection state characteristic of the AP Find service according to the GATT profile of BLE. At this time, if the detection state characteristic is "detection start", the control unit B101 determines that the detection start notification has been received. When the control unit B101 determines that the detection start notification has been received, the process proceeds to step S903. On the other hand, if the control unit B101 determines that the detection start notification is not received, the process of step S1202 is repeated.

As described above, in the second embodiment of the present invention, the camera A100 notifies the smartphone B100 when the detection of the access point C100 is unnecessary. As a result, the camera A100 can stop the transmission of unnecessary detection notifications from the smartphone B100. Further, since the operation of BLE requires Advertise for any service, if the camera A100 stops the Advance of BLE, the operation of other BLE services in the camera A100 may be hindered. In the second embodiment, since Advanced is not stopped, BLE services other than AP Find can be used at the same time.

[Third Embodiment]
Subsequently, an example of a communication system including a communication device according to a third embodiment of the present invention will be described.

<Overview of the system>
In the second embodiment described above, when the smartphone B100 detects the access point C100, the case where the access point detection notification is transmitted to the camera A100 only when the detection start notification is received from the camera A100 has been described. In the third embodiment, a case where the smartphone B100 determines whether or not to transmit the access point detection notification according to the number of unuploaded images of the camera A100 will be described.

Since the configuration of the communication system according to the third embodiment is the same as that of the communication system shown in FIG. 1, the description thereof will be omitted here. Further, it is assumed that the digital camera A100 and the smartphone B100 have been paired in advance. In the third embodiment, in addition to the characteristics described in the first embodiment, the AP Find service includes an image number characteristic for notifying the smartphone B100 of the number of unuploaded images from the camera A100. Then, at the time of pairing, the camera A100 performs the AP Find service Advantage with the image number characteristic as "0 image".

FIG. 13 is a sequence diagram for explaining a flow of processing from access point detection to image transmission in a communication system including a communication device according to a third embodiment of the present invention. In FIG. 13, the same steps as those shown in FIG. 7 are designated by the same reference numerals and the description thereof will be omitted.

In step S1301, the camera A100 accepts a process such as shooting by a user to change the number of unuploaded images. Then, when the power OFF operation is accepted by the power switch, in step S1302, the camera A100 transmits a notification of the number of unuploaded images to the smartphone B100 by BLE. After that, in step S1303, the camera A100 goes into a standby state.

Upon receiving the image number notification from the camera A100, in step S1304, the smartphone B100 determines whether or not to start transmitting the access point detection notification. The determination made in step S1304 will be described later.

After the process of step S717, in step S1305, the camera A100 transmits an unuploaded image number notification to the smartphone B100 by BLE before shifting to the standby state. Then, the camera A100 shifts to the standby state in step S718.

Upon receiving the notification of the number of unuploaded images from the camera A100, in step S1306, the smartphone B100 determines whether or not to stop the transmission of the access point detection notification. The determination made in step S1306 will be described later.

In the illustrated example, the number of images notified in step S1305 is 0 because the image transmission is performed in step S716. Therefore, the smartphone B100 will stop transmitting the access point detection notification.

<Operation of each device>
FIG. 14 is a flowchart for explaining the operation of the camera when transmitting an image in the communication system according to the third embodiment of the present invention. In the flowchart shown in FIG. 14, the same steps as those in the flowchart shown in FIG. 8 are designated by the same reference numerals and the description thereof will be omitted. Further, the processing according to the illustrated flowchart is performed under the control of the control unit A101 and the sub-control unit A120.

The process according to the flowchart shown in FIG. 14 is started when the power switch provided in the operation unit A105 instructs the control unit A101 to turn off the power. When the sub-control unit A120 determines that the Central ID information exists, in step S1401, the control unit A101 counts the number of unuploaded images stored in the recording medium A110. Then, the control unit A101 transmits a notification of the number of unuploaded images to the smartphone B100 by the power-saving wireless communication unit A112.

For example, the control unit A101 transmits the image number characteristic of the AP Find service according to the GATT profile of BLE. At this time, the number of unuploaded images is written in the image number characteristic. The process of step S1401 corresponds to the process of step S1302 shown in FIG.

Subsequently, in step S1402, the control unit A101 shifts the camera A100 to the standby state by the power management unit A107. After that, the process proceeds to step S811.

After performing the process of step S808 described above, in step S1403, the control unit A101 counts the number of unuploaded images stored in the recording medium A110. Then, the control unit A101 transmits a notification of the number of unuploaded images to the smartphone B100 by the power saving wireless communication unit A112. For example, the control unit A101 transmits the image number characteristic of the AP Find service according to the GATT profile of BLE. At this time, the number of unuploaded images is written in the image number characteristic. The process of step S1403 corresponds to the process of step S1305 shown in FIG.

In the flowchart shown in FIG. 15, the same steps as those in the flowchart shown in FIG. 9 are designated by the same reference numerals and the description thereof will be omitted. Further, the processing related to the illustrated flowchart is performed under the control of the control unit B101.

If the control unit B101 determines in step S910 that the Peripheral ID information exists, the process proceeds to the process of step S1501. In step S1501, the control unit B101 determines whether or not the power saving wireless communication unit B112 has received the image number notification from the camera A100. For example, the control unit A101 determines whether or not the image number characteristic of the AP Find service according to the GATT profile of BLE has been received.

Upon receiving the image number notification, the control unit B101 reads the image number characteristic and proceeds to the process of step S1502. On the other hand, if the image number notification is not received, the control unit B101 repeats the process of step S1501.

In step S1502, the control unit B101 determines whether or not the number of images received in step S1501 is equal to or greater than a predetermined number. When the control unit B101 determines that the number of images is equal to or greater than the predetermined number, the process proceeds to step S901.
