FIG. 3 is a diagram schematically showing a connection form between the digital camera 100 and the mobile phone 200 in the present embodiment. When the digital camera 100 and the mobile phone 200 transmit and receive data wirelessly, two connection forms shown in FIGS. 3A and 3B are possible.
FIG. 3A shows a form in which the digital camera 100 and the mobile phone 200 participate in a wireless LAN network formed by an external AP 300 that is an example of an external relay device. The digital camera 100 and the mobile phone 200 detect a beacon signal periodically transmitted by the external AP 300 and participate in a wireless LAN network formed by the external AP 300. After participating in the same wireless LAN network, the digital camera 100 and the mobile phone 200 are ready to transmit and receive data via the wireless LAN through mutual device discovery and device capability acquisition (establish communication between devices). .
Further, the external AP 300 in this embodiment can be connected to an external network such as the Internet using a public network or the like. Therefore, the mobile phone 200 can transmit data over the Internet via the external AP 300.

FIG. 3B illustrates a form in which the digital camera 100 and the mobile phone 200 are directly connected without using the external AP 300. In this case, the digital camera 100 operates as a simple AP to form a wireless LAN network. When the digital camera 100 operates as a simple AP, the digital camera 100 starts to periodically transmit a beacon signal. The mobile phone 200 detects the beacon signal and participates in the wireless LAN network formed by the digital camera 100. As in the case of FIG. 3A, communication is established through mutual device discovery, device capability acquisition, and the like, and data transmission and reception is possible.
As described above, the digital camera 100 in this embodiment does not have a function of communicating with an external network such as the Internet. Therefore, the mobile phone 200 participating in the wireless LAN network formed by the digital camera 100 cannot transmit data to the Internet or the like via the simple AP.
As described above, the digital camera 100 and the mobile phone 200 have two connection forms. In the present embodiment, the digital camera 100 and the mobile phone 200 are directly connected without using the external AP 300 in FIG.

FIG. 4 is an explanatory diagram of a use case for providing an image from the digital camera 100 to the mobile phone 200 according to the present embodiment. Assume that the owner A of the digital camera 100 is participating in a bus tour. Tour participants B, C, and D each own a mobile phone 200. The participant D is assumed to be an old friend with the owner A.
The owner A of the camera took a bus tour together with his friend D and happened to be close together with B and C, so he went sightseeing together and took pictures during the tour. Since only A carries the digital camera 100 on that day, it is assumed that all the captured pictures are stored in the digital camera 100 of A. In such a case, for example, the owner A may be asked to see a photograph taken by the bus tour from B, C, and D in the bus of the returning bus.

Generally, when it is said that you want to show the captured image, it is easiest for the owner of the camera to give the camera to the person who wants to see the picture and see the image in the camera directly It is. However, if the camera contains an image that you do not want to show, the method cannot be executed.
As a method of showing only the selected image, it can be used for a service such as a web album later. However, as in this case, it takes time and effort to exchange the contact information with B and C, which are not related to the old knowledge, and to contact at a later date. As the owner A of the digital camera 100, it is less troublesome to show it easily on the spot. In addition, the owner A may show images to B and C, which are not so close, but there may be a case where only the friend D wants to give the image.

In such a situation, the information processing system according to the present embodiment changes the type of image to be disclosed in accordance with the closeness between the partner who requested the image browsing and itself. Specifically, the following use cases are assumed. That is, first, as shown in FIG. 4A, A is requested to view an image by a tour companion or the like.
As shown in FIG. 4B, when A is requested for a thumbnail image, A selects only the images related to the tour from the captured images in the digital camera 100 and requests the corresponding thumbnail image. It operates so that it may transmit to the mobile phone 200 of all the other parties. Further, as shown in FIG. 4C, A transmits a captured image only to the mobile phone 200 of a specific partner among the partners who requested image acquisition. For example, in the example illustrated in FIG. 4, A provides a captured image only to the friend D. That is, accompanying persons B and C other than the friend D can browse the thumbnail image, but cannot acquire the captured image itself.

As in the above case, the owner of the digital camera 100 has a desire to publish the photographed image widely and casually, but there is a conflicting request that he / she wants to select the image to be shared and the person to whom the image is to be handed over. There is. In order to realize this demand, the digital camera 100 according to the present embodiment transmits captured images and thumbnail images using different communication methods. Specifically, the digital camera 100 uses two communication methods, Bluetooth and a wireless LAN network. Here, the communication in Bluetooth in this embodiment can be connected without pairing, and simultaneously connects to and communicates with a number of partner devices. In addition, the wireless LAN in the present embodiment basically communicates only with a single counterpart device at the same time.
In the present embodiment, the digital camera 100 transmits a thumbnail image corresponding to the captured image to the mobile phone 200 via Bluetooth. Thereafter, when the digital camera 100 receives a captured image acquisition request corresponding to the thumbnail image from the mobile phone 200, the digital camera 100 transmits the requested public image to the mobile phone 200 via the wireless LAN network.

FIG. 5 is a sequence diagram showing processing of the digital camera 100 and the mobile phone 200. In step S <b> 501, the digital camera 100 performs public setting of thumbnail images according to a user operation (setting process). The digital camera 100 recognizes that the thumbnail image that has been set to be public is permitted to be disclosed to an unspecified number of people.
FIG. 6 is a diagram showing an example of a public setting screen 600 displayed on the display unit 106 of the digital camera 100 in S501. When the user determines that the thumbnail image corresponding to the captured image displayed on the publish setting screen 600 may be disclosed, the user selects the OK button 501. When the OK button 501 is selected, the digital camera 100 accepts a public setting instruction for a thumbnail image corresponding to the captured image being displayed. Then, the digital camera 100 performs the public setting for the thumbnail image according to the public setting instruction. The digital camera 100 completes the public setting by performing this operation on each thumbnail image.

As another example, the digital camera 100 may manage the validity / invalidity of Bluetooth communication (communication control processing), and perform the public setting depending on whether the communication is valid. Specifically, the control unit 101 of the digital camera 100 performs the public setting for the thumbnails that are captured with Bluetooth “ON”, that is, in a state where Bluetooth communication is enabled . In this case, the control unit 101, Bluetooth "OFF", i.e. not performed visibility for imaging thumbnail in a communication disabled state of Bluetooth. Further, when the digital camera 100 captures an image with Bluetooth “ON”, the digital camera 100 confirms with the user whether or not the thumbnail image can be disclosed immediately after the image capture, and only when the input of the disclosure setting instruction by the user is accepted. It is good also as setting.

There are cases where private images are mixed in the digital camera 100 as shown in FIG. Even in such a case, the digital camera 100 performs the public setting only for the captured image that the user desires to open by inputting the public setting instruction only for the thumbnail image that the user wants to show to others. be able to. Here, the digital camera 100 performs the public setting by storing the list information indicating the thumbnail image related to the public setting instruction in the recording medium 110 as an external file different from the thumbnail image.
As another example, the digital camera 100 may perform the public setting by adding (embedding) setting information indicating that the public setting has been made to the thumbnail image related to the public setting.

In subsequent S502, the digital camera 100 sets Bluetooth to “ON” in response to a user operation. Next, in S503, the mobile phone 200 activates an application in response to a user operation. Next, in S504, the digital camera 100 and the mobile phone 200 establish a connection with Bluetooth. Hereinafter, the data communication in S505 to S511, S521, and S522 is realized by Bluetooth.
In step S <b> 505, the mobile phone 200 transmits an image list request to the digital camera 100. Here, the image list request is information for requesting an image list, and the image list is list display information for displaying a list of thumbnail images that are recorded in the digital camera 100 and set publicly. That is, the image list transmitted in S506 includes only thumbnail images that are set to be public, and does not include thumbnail images that are not set to be public. In step S <b> 506, the digital camera 100 transmits an image list to the mobile phone 200 in response to the image list request.

When the user of the mobile phone 200 desires to obtain a thumbnail image, the user selects the desired thumbnail image by operating the mobile phone 200. In response to this, in step S507, the mobile phone 200 transmits to the digital camera 100 a request for acquiring a thumbnail image selected by the user from among the thumbnail images included in the image list. In step S508, the digital camera 100 transmits a thumbnail image related to the acquisition request. Then, when the mobile phone 200 receives the thumbnail image, it displays it on the display unit 206.
As described above, the Bluetooth connection is characterized in that it can be connected without pairing and can be connected simultaneously with a large number of partners. For this reason, in S508, the digital camera 100 can transmit the image list and thumbnail images to an unspecified number of people including those who are not known as shown in FIG. 4B.

Subsequently, when the user of the mobile phone 200 desires to obtain a captured image corresponding to the thumbnail image, the user selects the thumbnail image corresponding to the desired captured image by operating the mobile phone 200. In contrast, in step S509, the mobile phone 200 transmits a captured image acquisition request corresponding to the thumbnail image selected by the user to the digital camera 100.
FIG. 7 is a diagram illustrating an example of a thumbnail display screen 700 displayed on the display unit 206 of the mobile phone 200. In the example of FIG. 7, the thumbnail images are displayed in three columns, and further thumbnail images can be displayed by scrolling up and down.
The user browses the thumbnail images on the thumbnail display screen 700 and selects a thumbnail image corresponding to the captured image that the user wants to acquire. As a result, a check 701 is displayed on the selected thumbnail image. When the selection of thumbnail images is completed, the user selects the save button 702. Corresponding to this, the mobile phone 200 accepts image selection in step S509, with the image given the check 701 as the image selected by the user.

In step S <b> 510, the mobile phone 200 transmits a captured image acquisition request corresponding to the selected thumbnail image to the digital camera 100. At this time, the mobile phone 200 transmits the captured image ID related to the acquisition request and the information of the mobile phone 200 itself to the digital camera 100.
In step S <b> 511, the digital camera 100 displays the received captured image acquisition request on the display unit 106. FIG. 8 is a diagram illustrating an example of a request display screen 800 displayed on the display unit 106 of the digital camera 100. The user of the digital camera 100 determines whether or not to respond to the captured image acquisition request, and selects the OK button 801 when permitting the request, or the cancel button 802 when rejecting. The digital camera 100, OK button 801 accepts authorization information obtaining the selected request, accepts deny information acquisition request and the cancel button 802 is selected (reception processing).

  The request display screen 800 displays a thumbnail image corresponding to the captured image for the acquisition request, information about the acquisition request transmission source mobile phone 200, and the like. Assume that the owner A of the digital camera 100 wants to send a captured image only to the friend D. In this case, the user of the digital camera 100 can confirm that the transmission source of the captured image acquisition request is the friend D by looking at the information of the mobile phone 200 displayed on the request display screen 800.

If the digital camera 100 receives the permission information of the acquisition request in S511, the digital camera 100 stores the image ID of the captured image and the information of the mobile phone 200 related to the acquisition request in the work memory 104, and advances the process to S512. On the other hand, if the digital camera 100 receives the rejection information of the acquisition request in S511, the process proceeds to S521.
