The system control unit 308 of the imaging apparatus 101 transmits a transmission unit tag to the server apparatus 103 together with the selected image. After that, when a new image to be transmitted is selected by the user, the system control unit 308 generates a transmission unit tag different from the previous one. Therefore, the CPU 201 of the server apparatus 103 can distinguish the transmission process of each image by referring to the transmission unit tag.

(Transfer processing of image of imaging device to client device by server device)
Next, an operation when the server apparatus 103 transfers the image of the imaging apparatus 101 to the client apparatus 102 will be described with reference to FIG.
The CPU 201 of the server apparatus 103 determines whether or not a request for referring to the untransfer list URL held in the server apparatus 103 has been received from the client apparatus 102 (step S1001). If not received, the process of step S1001 is repeated. When the request is received (Yes in step S1001), the CPU 201 acquires an untransfer list corresponding to the untransfer list URL and transmits the image URL of the image to be transferred to the client apparatus 102 (step S1002). The CPU 501 of the client apparatus 102 transmits an image acquisition request by referring to the received image URL to the server apparatus 103. Here, an image URL indicating that the transfer status 724 is not transferred is transmitted.
When the CPU 201 of the server apparatus 103 receives an image acquisition request by referring to the image URL from the client apparatus 102, the CPU 201 reads an image corresponding to the image URL (step S1003). The CPU 201 transmits the read image to the client device 102 (step S1004).
Thereafter, the CPU 501 of the client device 102 receives the image from the server device 103 and stores it in a predetermined storage area of the external storage device 504, for example. The CPU 501 of the client apparatus 102 transmits a notification of successful image reception to the server apparatus 103 every time the image storage is successful.

(Process to notify the communication device of the transfer status to the client device by the server device)
Next, the operation when the server apparatus 103 notifies the communication apparatus 105 of the image transfer status to the client apparatus 102 will be described with reference to the flowchart of FIG.
The CPU 201 of the server apparatus 103 determines whether a notification of successful image reception has been received from the client apparatus 102 (step S1101). If not received, the process of step S1101 is repeated. When the notification is received (Yes in step S1101), the CPU 201 specifies an image to be notified (step S1102). The CPU 201 updates the transfer status of the specified image (step S1103). As shown in FIG. 7C, when the server apparatus 103 receives an image from the imaging apparatus 101 (Yes in step S901) and stores it in the storage device 204 (step S903), the transfer status 724 corresponding to the image is displayed. Stores a value indicating untransferred. Thereafter, when the server apparatus 103 receives a notification of successful image reception from the client apparatus 102 (Yes in step S1101), the transfer status 724 corresponding to the image is overwritten and stored with a value indicating that transfer has been completed.

  The CPU 201 determines whether or not a reception success notification has been received for all images for each transmission unit tag (step S1104). If there is no transmission unit that has received a notification of successful reception for all the included images, the process returns to step S1101. On the other hand, if there is a transmission unit tag that has received a reception success notification for all the included images (Yes in step S1104), the process proceeds to the next process. Based on the notification destination setting information associated with the transmission unit tag, the CPU 201 notifies the communication device 105 that the transfer has been completed (step S1105).

  Even when the reception success notification is not received for all the images included in the transmission unit tag, the CPU 201 of the server device 103 sends the image to the communication device 105 after a predetermined time has elapsed after receiving the image from the imaging device 101. You may be notified. Even if the notification of successful reception is not received for all the images included in the transmission unit tag, the CPU 201 of the server apparatus 103 communicates after a predetermined time has elapsed after receiving the image acquisition request from the client apparatus 102. The device 105 may be notified. When notifying the communication device 105 without successful reception in this way, the CPU 201 indicates that all the images have not been received yet, information for identifying the images that have been successfully received, or images that have not yet been successfully received. Information for identification is notified as a message. The information for identifying an image that has been successfully received or the information for identifying an image that has not been successfully received includes, for example, a thumbnail image corresponding to the image.

Further, the CPU 201 may include a thumbnail image obtained by reducing the image in the information notified to the communication device 105.
In addition, the CPU 201 of the server device 103 receives a notification of successful image reception from the client device 102, thereby deleting the corresponding image from the storage device 204 and deleting data (for example, an image URL) associated with the image. You may do it. This deletion process may be performed in transmission units.

  As described above, according to the present embodiment, when the client apparatus 102 receives from the server apparatus 103 all the images of the common transmission unit tag transmitted from the imaging apparatus 101 to the server apparatus 103, the server apparatus 103 notifies the user. Notice. Therefore, the user is notified every time an image is transferred and does not feel annoying, and usability can be improved.
