In the following, after showing the overall image of the data sharing system according to the first embodiment, the processing flow in the data sharing system is shown, the configuration of the data sharing system is shown, and then the detailed processing flow is shown.

[Overview of data sharing system]
The overall image of the data sharing system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an overview of processing by the data sharing system according to the first embodiment. In FIG. 1, reference numeral 100 denotes a photographing apparatus that is carried by a user and photographs image data. The photographing apparatus 100 corresponds to, for example, a digital camera. In the example illustrated in FIG. 1, 100a is a photographing device used by the user A, and 100b is a photographing device used by the user B.

  In FIG. 1, reference numeral 200 denotes a wireless device carried by the user. The wireless device 200 performs short-range wireless communication with another wireless device 200. Near field communication corresponds to, for example, near field communication called Bluetooth or ZigBee. The wireless device 200 is, for example, a portable wireless device such as a mobile phone having a function of performing short-range wireless communication, a PHS (Personal Handyphone System), a smartphone, or a PDA (Personal Digital Assistant). In the example illustrated in FIG. 1, 200 a is a wireless device used by user A, and 200 b is a wireless device used by user B.

  In FIG. 1, reference numeral 300 denotes an image sharing server that stores image data acquired by a user. Reference numeral 400 denotes an image reference device used by a user who refers to image data.

  In FIG. 1, reference numeral 10 denotes a user of the data sharing system. In the example illustrated in FIG. 1, 10 a is the user A and 10 b is the user B. Reference numeral 11 denotes a wireless range that is a range in which short-range wireless communication transmitted by the wireless device 200 reaches. In the example illustrated in FIG. 1, 11a is a wireless range of short-range wireless communication transmitted by the wireless device 200a, and 11b is a wireless range of short-range wireless communication transmitted by the wireless device 200b. Hereinafter, the case where the wireless device 200b is included in the wireless range 11a of the wireless device 200a will be described. Further, the case where the user ID for identifying the user A is the user ID “A” and the user ID for identifying the user B is the user ID “B” will be described.

  As illustrated in (1) of FIG. 1, when the wireless device 200 enters the wireless range of another wireless device 200, the wireless device 200 transmits the user ID of the user who uses the other wireless device 200 transmitted by the other wireless device 200. Receive. For example, in the example illustrated in FIG. 1, the wireless device 200a and the wireless device 200b exchange user IDs when they detect each other.

  The user ID is also referred to as “identification information”. Also, the user ID of the user who uses the device that is the processing subject is also referred to as “own user ID”, “self-identification information”, or “first identification information”, and is another wireless device that is different from the device that is the processing subject. The user ID of the user who uses 200 is also referred to as “other user ID”, “other identification information”, or “second identification information”. For example, taking the photographing apparatus 100a as an example, the user ID “A” of the user A who uses the photographing apparatus 100a becomes the own user ID, and the user ID “B” of the user B who uses the photographing apparatus 100b becomes the counterpart user ID. In the following, a user who uses another wireless device 200 different from the device that is the processing subject is also referred to as a “partner user”.

  Returning to the description of FIG. As illustrated in (2a) and (2b) in FIG. 1, the wireless device 200 transmits the counterpart user ID to the imaging device 100. For example, the wireless device 200a transmits the partner user ID “B” to the photographing device 100a, and the wireless device 200b transmits the partner user ID “A” to the photographing device 100b.

  In addition, as illustrated in (3a) and (3b) of FIG. 1, the imaging device 100 captures image data. For example, the imaging device 100a periodically captures images in the vicinity of the user A. Explaining with a more detailed example, the imaging device 100a periodically captures image data in front of the user A in the direction of the line of sight regardless of the will of the user A. Similarly, the imaging device 100b periodically images image data in front of the user B.

  Then, as illustrated in (4a) and (4b) in FIG. 1, when the photographing apparatus 100 receives the counterpart user ID transmitted from the wireless apparatus 200 by the identification information transmitting unit, the wireless apparatus 200 receives another wireless apparatus 200. The other party user ID is associated with the image data taken in the receivable time zone using short-range wireless communication. Then, the imaging device 100 transmits the image data to the image sharing server 300.

  For example, for image data captured by the image capturing device 100a during a time period in which the wireless device 200a can receive the user ID “B” from the wireless device 200b, the image capturing device 100a sets the own user ID “A” and the partner user “B”. Is associated with the image data. The photographing apparatus 100a transmits the image data to the image sharing server 300 at a predetermined opportunity. For example, the imaging device 100a transmits the image data to the image sharing server 300 every time the image data is captured, transmits the image data to the image sharing server 300 every time the image data is captured a predetermined number of times, and stores the image data during the predetermined period. Send to.

  Thereafter, as shown in FIG. 1 (5), the image sharing server 300 having the image information table for storing the image information transmitted from the photographing apparatus 100 is associated with an arbitrary user ID from the image information table. The data is extracted as image data that can be used by the user identified by the arbitrary user ID. For example, the case where user A refers to image data will be described. In this case, the image sharing server 300 extracts image data associated with the own user ID “A”. In other words, the image sharing server 300 extracts the image data captured by the counterpart user ID “A”. Further, the image sharing server 300 extracts image data associated with the partner user “A”.

  As a result, the image sharing server 300 extracts, as image data usable by the partner user, image data captured by the user during the time period when the partner user was in the wireless range of the user. For example, the image sharing server 300 extracts image data captured by the image capturing device 100a when the wireless device 200b is within the wireless range 11a of the wireless device 200a as image data usable by the user B. In other words, the image sharing server 300 extracts the image data captured by the user A when the user A and the user B are close as image data usable by the user B. As a result, in the image sharing server 300, for example, the user B can use image data including the user B photographed by the user A, and the user B can use image data around the user B photographed by the user A.

  Thus, according to the data sharing system in the first embodiment, data other than the data acquired by the user himself / herself can be used. For example, according to the data sharing system, it is possible to easily use image data other than the image data captured by the user himself without the user being particularly conscious.

  Also, according to the data sharing system, image data is transmitted to the image sharing server 300 every time the image capturing device 100 captures an image, and the image capturing device 100 transmits the image after associating the other user. Can be shared immediately after shooting. For example, even when one user wants to view the image of the other user who was taken immediately before, it can be acquired immediately. The image data received by the image sharing server 300 is associated with the other user ID, and can be made available to the other user as soon as the image sharing server 300 receives the image data.

[Flow of Shooting Process and User ID Reception Process]
With reference to FIG. 2, an example of a flow of shooting processing performed by the shooting device 100 and an example of a flow of user ID reception processing performed by the wireless device 200 according to the first embodiment will be described. FIG. 2 is a sequence diagram illustrating an example of a flow of shooting processing by the shooting device and an example of a flow of user ID reception processing by the wireless device according to the first embodiment. A series of processing shown in FIG. 2 corresponds to (1) and (3) in FIG. In FIG. 2, for convenience of explanation, the description will be made using two imaging devices 100 and two wireless devices 200, but the present invention is not limited to this, and an arbitrary number of imaging devices 100 and wireless devices 200. There is good. In FIG. 2, description of the point that the wireless device 200 transmits the partner user ID to the image capturing device 100 and the point that the image capturing device 100 transmits image data to the image sharing server 300 will be omitted.

  As illustrated in FIG. 2, the image capturing apparatus 100a periodically captures image data in front of the user A (steps S101 to S103). Similarly, the imaging device 100b periodically captures image data in front of the user B (steps S201 to S203).

  In addition, the wireless device 200a and the wireless device 200b periodically search for other users and notify the user ID (steps S301 to S316). In the example illustrated in FIG. 2, a case will be described in which the wireless device 200 exchanges user IDs after confirming that identification information can be transmitted and received with other wireless devices 200.

  As illustrated in FIG. 2, the wireless device 200a and the wireless device 200b transmit a service ID response request for requesting a response to the wireless range of the own wireless device 200 (steps S301 to S302). For example, the wireless device 200a transmits a service ID for identifying a service to which the wireless device 200a corresponds. Here, when receiving the service ID response request, the wireless device 200b transmits a service ID response that is a response to the service ID response request (step S303). For example, when the wireless device 200b receives the service ID, the wireless device 200b determines whether the service corresponds to the service corresponding to the received service ID. If the wireless device 200b determines that the service ID corresponds, the wireless device 200b transmits a service ID response. As a result, a connection is established between the wireless device 200a and the wireless device 200b (step S304). That is, the identification information can be transmitted and received between the wireless device 200a and the wireless device 200b.

  The wireless device 200a and the wireless device 200b exchange user IDs (steps S305 to S308). For example, the wireless device 200a transmits the user ID “A” to the wireless device 200b (step S305). Thereafter, the wireless device 200b stores the user ID “A” received from the wireless device 200a as a counterpart user ID in a communication information table described later, and stores the own user ID “B” and the connection establishment time in a communication information table described later. Store (step S306). Also, the wireless device 200b transmits the user ID “B” to the wireless device 200a (step S307). Thereafter, the wireless device 200a stores the user ID “B” received from the wireless device 200b as a counterpart user ID in a communication information table described later, and stores the own user ID “A” and the connection establishment time in a communication information table described later. Store (step S308).

  Also, the wireless device 200 periodically checks whether a connection is established, and stores the connection release time in a communication information table described later when the connection is released (steps S309 to S316).

  For example, the wireless device 200a transmits the partner user ID “B” that has established the connection to the wireless device 200b (step S309). Then, upon receiving the user ID “B” transmitted by the wireless device 200a, the wireless device 200b transmits the user ID “A” that is the counterpart user ID for the wireless device 200b to the wireless device 200a (step S310). Here, for example, after transmitting the user ID “B” (step S311), the wireless device 200a determines that the connection has been released when there is no response within a predetermined time (step S312). That is, the wireless device 200a determines that identification information cannot be transmitted / received to / from the wireless device 200b. Then, the wireless device 200a stores the connection release time in a communication information table described later in association with the counterpart user ID “B” (step S313). In addition, the wireless device 200b performs the same processing, and stores the connection release time in a communication information table described later (steps S314 to S316).

  Here, referring to FIG. 2, image data that can be used by the user B in the image data captured by the image capturing apparatus 100 a, and image data that can be used by the user A in the image data captured by the image capturing apparatus 100 b. Will be described. As described above, the wireless device 200 uses the connection establishment time and the connection release time as time zone information. In this case, among the image data captured by the image capturing apparatus 100b, image data captured after the connection establishment time and before the connection release time is made available to the user A. In the example illustrated in FIG. 2, the image data captured in step S <b> 102 can be used by the user B. Similarly, the image data captured in step S202 can be used by the user A.

  An example of a flow of processing in which the wireless device 200 transmits the counterpart user ID to the image capturing device 100 and an example of a flow of processing in which the image capturing device 100 transmits image data to the image sharing server 300 will be described with reference to FIG. FIG. 3 is a sequence diagram illustrating an example of a process flow in which the wireless apparatus according to the first exemplary embodiment transmits a partner user ID to the image capturing apparatus and an example of a process flow in which the image capturing apparatus transmits image data to the image sharing server. is there. In describing FIG. 3, the same points as in FIG. 2 will be briefly described. In FIG. 3, a case where the wireless device 200a transmits to the image capturing device 100a and the image capturing device 100a transmits to the image sharing server 300 will be described.

  In the following, communication is information in which the wireless device 200a includes its own user ID, a partner user ID, and time zone information that identifies a time zone in which the wireless device 200a can receive the partner user ID from another wireless device 200b. The case where information is transmitted to the imaging apparatus 100a will be described. For example, the time zone information includes a connection establishment time indicating a time when the connection with the other wireless device 200b is established and the user ID can be transmitted and received, and a time when the connection is released and the user ID cannot be transmitted and received. Connection release time indicated.

  However, the present invention is not limited to this. For example, the wireless device 200 may transmit only the counterpart user ID, or may further transmit information other than the own user ID, the counterpart user ID, and the time zone information. Further, the wireless device 200 may use the time when the information from the other wireless device 200 can be received instead of the connection establishment time, and the time when the information cannot be received from the other wireless device 200 is connected. It may be used instead of the release time.

  Note that, in a time zone in which the user ID can be received from the user's wireless device 200 identified by the counterpart user ID, the wireless device 200 can receive short-range wireless communication transmitted by the other wireless device 200, and Each device 200 is within a predetermined range. For this reason, in the time zone identified by the time zone information, the image data shot by the other user's shooting device 100 becomes image data obtained by shooting the situation around him, for example, an image of himself / herself taken. It becomes data.

  Returning to the description of FIG. When the wireless device 200a and the wireless device 200b establish a connection (step S401), the wireless device 200a and the wireless device 200b exchange user IDs (steps S402 to S405). Thereafter, the wireless device 200a transmits communication information including the own user ID “A”, the partner user ID “B”, and the connection establishment time to the imaging device 100a (step S406).

  Thereafter, the wireless device 200 periodically checks whether a connection has been established (steps S407 to S409), and stores the connection release time in a communication information table described later when the connection is released (step S410). (Step S411). Then, the wireless device 200a transmits communication information including the own user ID “A”, the partner user ID “B”, and the connection release time (step S412).

  On the other hand, the imaging device 100a periodically captures image data (steps S501 to S504). Here, when receiving the communication information including the partner user ID “B” and the connection establishment time, the imaging apparatus 100a associates the own user ID and the partner user ID with the image data (step S601), The image information including the counterpart user ID and the image data is transmitted to the image sharing server 300 (steps S602 and S603).

  For example, when receiving the communication information, the image capturing apparatus 100a searches for image data that has already been captured after the connection establishment time of the received communication information, and acquires, for example, the image A10 to the image A13 captured in step S502. Then, the imaging apparatus 100a associates the own user ID “A” and the counterpart user ID “B” with the images A10 to A13, and includes the own user ID “A”, the counterpart user ID “B”, and image data. The image information is sequentially transmitted to the image sharing server 300 (step S602). In addition, the image capturing apparatus 100 a associates the own user ID and the partner user ID with the image data captured after receiving the communication information, and transmits the image data to the image sharing server 300. For example, the imaging device 100a sequentially associates the own user ID “A” with the counterpart user ID “B” every time image data is captured for the images A14 to A18 captured in step S503. The image is transmitted to the image sharing server 300 (step S603).

  In the example illustrated in FIG. 3, when the image capturing apparatus 100 a receives communication information, the image capturing apparatus 100 a sequentially associates the own user ID “A” and the partner user ID “B” every time image data is captured. Although the case of transmitting to the image sharing server 300 is shown as an example, the present invention is not limited to this. For example, the image capturing apparatus 100a may transmit image data to the image sharing server 300 at a predetermined opportunity. For example, the image capturing apparatus 100a may transmit image data to the image sharing server 300 every time image data is captured a predetermined number of times. Data may be transmitted to the image sharing server 300.

  After that, when receiving the communication information including the partner user ID “B” and the connection release time, the imaging device 100a stops the association of the partner user ID and stops the transmission of the image information (step S604).

[Image reference processing]
An example of the flow of the image reference process in the data sharing system according to the first embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of the flow of the image reference process in the first embodiment. A series of processing shown in FIG. 4 corresponds to (5) of FIG.

  As illustrated in FIG. 4, when the image reference device 400 receives a condition for specifying image data to be referenced from a user (step S <b> 701), the image reference device 400 includes a reference user ID and a condition that are user IDs for identifying a user who refers to the image data. Is sent to the image sharing server 300 (step S702). For example, when the user A uses the image reference device 400, the image reference device 400 transmits a reference request including the user ID “A”.

  Then, the image sharing server 300 extracts image data that matches the reference request from an image information table described later (step S703). For example, upon receiving a reference request including the user ID “A”, the image sharing server 300 extracts image data associated with the own user ID “A” and image data associated with the partner user “A”. To do. Then, the image sharing server 300 transmits the extracted image data (step S704). Thereafter, the image reference device 400 outputs the received image data to the user (step S705).
