Abstract

PROBLEM TO BE SOLVED: To smoothly perform a data transfer by reduction in chores.SOLUTION: A server 60 of a SNS system is configured to disclose personal information (name, a birth place, a graduation school, and the like) between users to thereby prepare and manage a friend list under both understandings. Digital cameras 10-1 and 10-2 are configured to acquire respective friend lists, from the server 60 of the SNS system, periodically, or as necessary, or upon occurrence of any event. The digital cameras 10-1 and 10-2 are connected by peer-to-peer or ad-hoc. The digital camera 10-1 on a transmission side is configured to transfer photographed image data to the digital camera 10-2 on a reception side under a condition where at least an owner of the digital camera 10-2 on the reception side is registered in a friend list of an owner of the digital camera 10-1 on the transmission side.

Description

  The present invention relates to data transfer of electronic equipment.

  Conventionally, as a technology for sharing images taken with a digital camera or camera-equipped mobile phone with other users, the photographed images are made public on the Internet, or other digital cameras or camera-equipped mobile phones. Or the like is used.

  For example, an image taken with a digital camera, a mobile phone with a camera, or the like can be obtained by using a site (server) on the Internet that provides a service such as SNS (Social Networking Service) as a relatively simple image data. A technique that is disclosed to a user designated by an image registrant is used (see, for example, Patent Document 1).

  In addition, in order to shoot one event or event using multiple digital cameras and create a single group of image data, a group is composed of multiple digital cameras, and a representative camera is determined from them. However, a technique for collecting images of digital cameras in a group on a representative camera has been proposed (see, for example, Patent Document 2).

  Also, when a close proximity wireless communication connection is established between a digital camera and an external device (including other digital cameras), the image selected by the user is transmitted to the external device, and the image transmitted immediately before is immediately before A technique has been proposed in which a user is inquired whether or not to transmit to a device other than the transmitted external device, and when transfer is selected by the user, connection to the next external device and image transmission are continuously performed ( For example, see Patent Document 3).

JP 2008-197968 A Japanese Patent Laid-Open No. 2003-087615 JP 2011-4389 A

  In the technique disclosed in Patent Document 1, in order to publish an image, it is necessary to transfer the image to the SNS server each time, and the image browsing side must also access the SNS server. However, depending on the communication environment at that time, there are cases where the SNS server cannot be accessed, and there is a problem that both the side for publishing images and the side for browsing images take time.

  In the technique disclosed in Patent Document 2, when grouping digital cameras that transfer image data, grouping information is exchanged to mutually confirm that they are groupable partners. However, the only requirement for selecting the representative camera is that it has a recording medium with a large recording capacity, and the representative camera is a digital camera of the other party (user) to which the image data may be transferred. There is no way to determine whether or not there is a problem that a procedure by a user operation is necessary and time-consuming.

  In the technique disclosed in Patent Document 3, when a connection for close proximity wireless communication is established with an external device, an image selected by the user is transmitted from the digital camera to the external device. However, as in the technique of Patent Document 2, there is no way to determine whether the external device (digital camera) of the other party (user) to which the image data can be transferred, and therefore a procedure by a user operation is necessary. There was a problem that it took time and effort.

When the digital cameras 10-1 and 10-2 are connected by peer-to-peer or ad hoc, if at least the email address of the receiving digital camera is registered in the friend list of the same SNS of the transmitting digital camera, Image data can be transferred. On the other hand, when the digital cameras 10-1 and 10-2 are connected by peer-to-peer or ad hoc, the mail address of the receiving digital camera is not registered in the same SNS friend list of the transmitting digital camera, Image data cannot be transferred.

B. Operation of Embodiment Next, the operation of the above-described embodiment will be described.
Hereinafter, the digital camera 10-1 will be described as the image data transmission side, and the digital camera 10-2 will be described as the image data reception side.

B-1. First Operation Example FIG. 4 is a flowchart for explaining the operation of the digital camera 10-1 on the transmission side according to the present embodiment. First, in the digital camera 10-1 on the transmission side, the CPU 18 establishes communication with the other digital camera 10-2 by the wireless communication unit 26 by peer-to-peer or ad hoc (step S10). Next, in the digital camera 10-1 on the transmission side, the CPU 18 transmits the SNS domain and the self-mail address (see FIG. 3A) to the other digital camera 10-2 by the wireless communication unit 26 (see FIG. 3A). Step S12). Next, the CPU 18 of the transmission-side digital camera 10-1 determines whether or not the partner's SNS domain and mail address have been received from the reception-side digital camera 10-2 (step S14).

  Here, the case where the other party's SNS domain and mail address are received means that the own mail address of the SNS domain transmitted to the digital camera 10-2 exists in the friend list of the other party's SNS domain. On the other hand, when the other party's SNS domain and e-mail address are not received, the SNS domain sent to the digital camera 10-2 on the receiving side is not in the other party's SNS domain, or the same SNS domain exists. The friend list was not present.

  Accordingly, when the SNS domain and mail address of the receiving digital camera 10-2 are not received (NO in step S14), an error display (or that image data cannot be transferred) is displayed (step S14). S18), the process proceeds to step S30 described later. On the other hand, when the SNS domain and mail address of the receiving digital camera 10-2 are received (YES in step S14), the CPU 18 of the transmitting digital camera 10-1 refers to the memory 20 and It is determined whether or not the SNS domain and mail address are registered in the friend list (step S16). When the SNS domain and mail address of the digital camera 10-2 on the receiving side are not registered in the friend list (NO in step S16), an error display (or that image data cannot be transferred) is displayed. (Step S18), the process proceeds to Step S30 described later.

  On the other hand, when the other party's SNS domain and mail address are registered in the friend list (YES in step S16), image data (one or more) to be transmitted to the receiving digital camera 10-2 is selected (step). S20). That is, at the stage of selecting the image data to be transmitted, the image data can be transmitted to the receiving digital camera 10-2 connected by peer-to-peer or ad hoc. For example, the CPU 18 of the transmission-side digital camera 10-1 displays a message such as “Image data can be transmitted. Select image data to be transmitted” on the display unit 22 and is recorded. A list (thumbnail) of captured image data is displayed. The user selects image data to be transmitted from a list (thumbnail) of image data. Alternatively, image data to be transmitted may be selected while displaying the image data slide by sheet. After selecting the image data, the user presses the transmission button of the key input unit 23.

  Next, the CPU 18 of the transmission-side digital camera 10-1 determines whether or not the transmission button of the key input unit 23 has been pressed by the user (step S22). If the send button has not been pressed (NO in step S22), the process returns to step S20 and continues to select image data. On the other hand, when the transmission button of the key input unit 23 is pressed by the user (YES in Step S22), the CPU 18 of the digital camera 10-1 on the transmission side converts the image data selected by the wireless communication unit 26 into the selected image data. It transmits to the digital camera 10-2 on the receiving side connected by peer-to-peer or ad hoc (step S24).

  Next, the CPU 18 of the digital camera 10-1 on the transmission side determines whether or not all the selected image data has been transmitted (step S26). If there is image data that has not yet been transmitted (NO in step S26), the CPU 18 of the digital camera 10-1 on the transmission side returns to step S24 and continues to transmit the selected image data. On the other hand, when all the selected image data has been transmitted (YES in step S26), a message such as “All image data has been transmitted” is displayed on the display unit 22 to notify the end of data. (Step S28).

  Next, the CPU 18 of the digital camera 10-1 on the transmission side determines whether or not the user has performed a communication end operation by peer-to-peer or ad hoc (step S30). If there is no operation for terminating communication by peer-to-peer or ad hoc (NO in step S30), the process returns to step S20 and the above-described processing is repeated. On the other hand, when there is a peer-to-peer or ad hoc communication end operation (YES in step S30), the CPU 18 of the digital camera 10-1 on the transmission side controls to disconnect the peer-to-peer or ad hoc communication by the wireless communication unit 26. (Step S32), and the process ends.

  FIG. 5 is a flowchart for explaining the operation of the digital camera 10-2 on the receiving side according to this embodiment. In the digital camera 10-2 on the receiving side, the CPU 18 first establishes communication with the other digital camera 10-1 by peer-to-peer or ad hoc at the wireless communication unit 26 (step S40). Next, in the digital camera 10-2 on the reception side, the CPU 18 uses the wireless communication unit 26 to specify the SNS domain and the other party's mail address (see FIG. 3A) transmitted from the digital camera 10-1 on the transmission side. Receive (step S42).

  Next, the CPU 18 of the receiving digital camera 10-2 refers to the memory 20 and determines whether or not the received SNS domain and mail address of the transmitting digital camera 10-1 are registered in the friend list. (Step S44). If the received SNS domain and email address are not registered in the friend list (NO in step S44), an error display (or that image data cannot be transferred) is displayed (step S46). ), The process proceeds to step S56 described later.

  On the other hand, when the SNS domain and mail address on the transmission side are registered in the friend list (YES in step S44), in the digital camera 10-2 on the reception side, the CPU 18 uses the wireless communication unit 26 to select the other party's digital The SNS domain and the self-mail address (see FIG. 3B) are transmitted to the camera 10-1 (step S48).

  That is, the fact that the digital camera 10-2 on the receiving side transmits its SNS domain and its own mail address to the digital camera 10-1 on the transmitting side means that the SNS domain on the side of the digital camera 10-1 on the transmitting side. This means that the e-mail address was registered in his friend list. That is, the owner of the digital camera 10-1 on the transmission side and the owner of the digital camera 10-2 on the reception side are registered in the friend list of the same SNS domain, and image data can be transmitted. It means that there is.

  When the receiving-side digital camera 10-2 transmits the SNS domain and its own mail address to the transmitting-side digital camera 10-1, the transmitting-side digital camera 10-1 shifts to an image data transmitting operation. (Steps S20 to S26 in FIG. 4 described above). In the digital camera 10-2 on the reception side, the CPU 18 determines whether or not the image data transmitted from the digital camera 10-1 on the transmission side has been received (step S50). If no image data has been received (NO in step S50), the process proceeds to step S56 described later. On the other hand, when image data is received (YES in step S50), the received image data is stored in the flash memory 21 or the memory card 25 (step S52).

  Next, the CPU 18 of the digital camera 10-2 on the receiving side determines whether or not all image data has been received (step S54). If there is image data that has not been received yet, that is, if image data is still transmitted (NO in step S54), the CPU 18 returns to step S50 and continues to receive and store the image data. On the other hand, when all the image data have been received (YES in step S54), the CPU 18 of the receiving digital camera 10-2 determines whether or not the user has performed an end operation of communication by peer-to-peer or ad hoc ( Step 56). Then, when there is no peer-to-peer or ad hoc communication termination operation (NO in step S56), the process returns to step S50 and the above-described processing is repeated. On the other hand, if there is a peer-to-peer or ad hoc communication end operation (YES in step S56), the CPU 18 of the receiving digital camera 10-2 controls to disconnect the peer-to-peer or ad hoc communication by the wireless communication unit 26. (Step S58), and the process ends.

B-2. Second Operation Example Next, a case where transmission is performed from the digital camera 10-1 on the transmission side in response to a transmission request from the digital camera 10-2 on the reception side will be described.

  FIG. 6 is a flowchart for explaining the operation of the digital camera 10-2 on the receiving side according to this embodiment. First, in the digital camera 10-2 on the receiving side, the CPU 18 establishes communication with the other digital camera 10-1 by peer-to-peer or ad hoc using the wireless communication unit 26 (step S70). Next, in the digital camera 10-2, the CPU 18 uses the wireless communication unit 26 to transmit the SNS domain and the self-mail address (see FIG. 3B) to the partner digital camera 10-1 (step S72). . Next, the CPU 18 determines whether or not the partner SNS domain and mail address are received from the partner digital camera 10-1 (step S74).

  Here, the case where the partner's SNS domain and mail address are received means that the self-mail address of the SNS domain transmitted to the digital camera 10-1 is present in the friend list of the partner SNS domain. On the other hand, when the partner's SNS domain and mail address are not received, the SNS domain transmitted to the digital camera 10-1 is not in the partner's SNS domain, or there is the same SNS domain, but the friend list It did not exist.

  Therefore, when the partner's SNS domain and mail address are not received (NO in step S74), an error display (or that image data cannot be transferred) is displayed (step S76), and step S96 described later is performed. Proceed to On the other hand, when the other party's SNS domain and mail address are received (YES in step S74), the transmission side digital camera 10-1 receives the SNS domain and own mail address of the owner of the receiving side digital camera 10-2. Is present in the friend list (meaning that transmission is possible), the CPU 18 determines whether or not the user has requested image data using the key input unit 23 (step S78). ). If there is no image data requesting operation (NO in step S78), the CPU 18 waits until there is an image data requesting operation.

  On the other hand, when the user performs an operation for requesting image data using the key input unit 23 (YES in step S78), the CPU 18 of the digital camera 10-2 on the reception side sends the digital camera 10-1 on the transmission side. On the other hand, a thumbnail list is requested (step S80). Next, the CPU 18 of the digital camera 10-2 receives the thumbnail list transmitted from the digital camera 10-1 on the transmission side in response to the request (step S82). Next, the CPU 18 of the digital camera 10-2 on the reception side selects image data (one or more) received from the digital camera 10-1 on the transmission side (step S84).

  For example, a message such as “Please select desired image data.” Is displayed on the display unit 22 and a list (thumbnail) of recorded image data is displayed, and image data that the user wants to receive is displayed. To select. The user selects desired image data from a list (thumbnail) of image data. Alternatively, desired image data may be selected while sliding the image data (low resolution) one by one. After selecting the image data, the user presses a transmission request button of the key input unit 23.

  Next, the CPU 18 of the digital camera 10-2 on the receiving side determines whether or not the transmission request button of the key input unit 23 has been pressed by the user (step S86). If the transmission request button has not been pressed (NO in step S86), the process returns to step S84 to continue selecting image data. On the other hand, when the transmission request button of the key input unit 23 is pressed by the user (YES in step S86), the CPU 18 of the digital camera 10-2 on the receiving side uses the wireless communication unit 26 to select the selected image data. Transmission is requested from the digital camera 10-1 on the transmission side connected by peer-to-peer or ad hoc (step S88).

  In the digital camera 10-2 on the reception side, the CPU 18 receives the image data transmitted from the digital camera 10-1 on the transmission side (step S90), and the received image data is stored in the flash memory 21 or the memory card 25. Store (step S92). Next, the CPU 18 of the digital camera 10-2 on the receiving side determines whether or not all image data has been received (step S94). If there is image data that has not yet been received (NO in step S94), the CPU 18 returns to step S090 and continues to receive and store the image data.

  On the other hand, when all the image data have been received (YES in step S94), the CPU 18 determines whether or not the user has performed an operation for terminating communication by peer-to-peer or ad hoc (step 96). If there is no operation for terminating communication by peer-to-peer or ad hoc (NO in step S96), the process returns to step S78 and the above-described processing is repeated. On the other hand, when there is a peer-to-peer or ad hoc communication termination operation (YES in step S96), the CPU 18 performs control to disconnect the peer-to-peer or ad hoc communication by the wireless communication unit 26 (step S98), and the processing Exit.

  FIG. 7 is a flowchart for explaining the operation of the digital camera 10-1 on the transmission side according to this embodiment. First, in the digital camera 10-1 on the transmission side, the CPU 18 establishes communication with the other digital camera 10-2 by the wireless communication unit 26 by peer-to-peer or ad hoc (step S110). Next, in the digital camera 10-1 on the transmission side, the CPU 18 receives the SNS domain and the partner mail address (see FIG. 3B) from the digital camera 10-2 on the reception side by the wireless communication unit 26 (see FIG. 3B). Step S112).

  Next, the CPU 18 of the receiving digital camera 10-2 refers to the memory 20 and determines whether or not the received SNS domain and mail address of the transmitting digital camera 10-1 are registered in the friend list. (Step S114). If the received SNS domain and e-mail address are not registered in the friend list (NO in step S114), an error display (or that image data cannot be transferred) is displayed (step S116). ), The process proceeds to step S132 described later.

  On the other hand, if the partner's SNS domain and mail address are registered in the friend list (YES in step S114), the CPU 18 of the digital camera 10-1 on the transmission side uses the wireless communication unit 26 to perform the digital camera 10 of the partner. The SNS domain and the self-mail address (see FIG. 3A) are transmitted to −1 (step S118).

  That is, the fact that the sending digital camera 10-1 sends its own SNS domain and its own mail address to the receiving digital camera 10-2 means that at least the receiving digital camera 10-2 side. This means that the SNS domain and e-mail address are registered in the friend list of the user, which means that image data can be transmitted.

  Next, the CPU 18 of the transmission-side digital camera 10-1 determines whether or not a thumbnail list request from the reception-side digital camera 10-2 has been received (step S120). If the thumbnail list request from the digital camera 10-2 on the receiving side has not been received (NO in step S120), the reception of the thumbnail list request is awaited. On the other hand, when a thumbnail list request is received from the digital camera 10-2 on the receiving side (YES in step S120), the CPU 18 of the digital camera 10-1 on the transmitting side stores it in the flash memory 21 or the memory card 25. The thumbnail list of the stored image data is transmitted to the receiving digital camera 10-2 (step S122).

  Next, the CPU 18 of the transmission-side digital camera 10-1 determines whether or not a transmission request is received from the reception-side digital camera 10-2 (step S124). If no transmission request has been received (NO in step S124), the reception of the transmission request is awaited. On the other hand, when a transmission request is received from the digital camera 10-2 on the reception side (YES in step S124), the CPU 18 of the digital camera 10-1 on the transmission side uses the wireless communication unit 26 to request the requested image data. Is transmitted to the digital camera 10-2 on the receiving side connected by peer-to-peer or ad hoc (step S126).

  Next, the CPU 18 of the transmitting digital camera 10-1 determines whether or not all requested image data has been transmitted (step S128). If there is image data that has not been transmitted yet (NO in step S128), the CPU 18 returns to step S126 and continues to transmit the requested image data. On the other hand, if all requested image data has been transmitted (YES in step S128), a message such as “All image data has been transmitted” is displayed on the display unit 22 to notify the end of data. (Step S130).

  Next, the CPU 18 of the digital camera 10-1 on the transmission side determines whether or not the user has performed an operation for terminating communication by peer-to-peer or ad hoc (step S132). Then, when there is no peer-to-peer or ad hoc communication termination operation (NO in step S132), the process returns to step S120, and the above-described processing is repeated. On the other hand, when there is a peer-to-peer or ad hoc communication termination operation (YES in step S132), the CPU 18 performs control to disconnect the peer-to-peer or ad hoc communication by the wireless communication unit 26 (step S134), and the processing Exit.

  According to the above-described embodiment, in the image data transfer between the digital cameras, the owner of the receiving digital camera corresponds to the “friend list” of the SNS registered in advance of the owner of the transmitting digital camera. In this case, the image can be transmitted, so that the other party (user) to whom the image data can be transferred can be automatically recognized. It is possible to reduce the user's trouble and smoothly transfer the image data.

  In addition, according to the above-described embodiment, the digital camera 10 is automatically and automatically acquired from time to time by acquiring a friend list from the SNS server in response to regular, irregular, or predetermined events. You can also update your friends list.

  Further, according to the above-described embodiment, since digital cameras are connected to each other by peer-to-peer or ad hoc, it is possible to prevent image data from being inadvertently diffused.

  In the above-described embodiment, the e-mail address registered in the SNS is used to authenticate the owner of the digital camera. However, the present invention is not limited to this. It may be a user ID or a registered name.
