The CPU 101 waits for reception of designation of the transfer date and time of image data by selecting a specific date and time among the date and time candidates displayed on the display unit 107 by the user operating the operation unit 106 (S15). At this time, instead of selecting the transfer date and time from the displayed candidates, a process of accepting the transfer date and time directly input by the user operating the operation unit 106 may be performed. If the transfer date / time designation is not received (S15: NO), the CPU 101 continues to wait for the transfer date / time designation reception. When designation of the transfer date / time is received (S15: YES), the CPU 101 displays the designated content including the image data to be transferred and the transfer date / time on the display unit 107 (S16).

  Next, the CPU 101 waits for reception of an e-mail transmission instruction when the user who has confirmed the content displayed on the display unit 107 operates the operation unit 106 (S17). If there is no reception of an e-mail transmission instruction (S17: NO), the CPU 101 returns the process to step S12. When an e-mail transmission instruction is received (S17: YES), the CPU 101 reserves information for instructing reservation of image data transfer, data specifying information for specifying image data to be transferred, and date / time information specifying transfer date and time. Is created (S18), the created email is transmitted from the communication unit 108 to the storage device 2 via the communication network N (S19), and the process is terminated.

However, the present invention is not limited to this, and image data is created by shooting. A mode in which the photographing apparatus 1 automatically creates and transmits an e-mail for reserving transfer of the created image data each time may be used.

  The user who has finished photographing with the photographing device 1 returns home and leaves the photographing device 1 in the user's home H. The storage device 2 performs processing for causing the photographing device 1 to transfer the image data when the transfer date and time designated by the e-mail instructing the reservation for the transfer of the image data comes.

  FIG. 6 is a flowchart showing a processing procedure for transferring image data according to the reservation information. The CPU 21 of the storage device 2 performs the following processing according to the program loaded in the RAM 22. Whenever the predetermined time elapses, the CPU 21 determines whether or not the transfer date and time designated by the e-mail instructing reservation for transfer of the image data has been reached based on the date and time counted by the clock unit 26 (S201). . When the transfer date / time has not yet been reached (S201: NO), the CPU 21 determines whether or not the transfer date / time has been reached each time a predetermined time elapses. When the designated transfer date and time has already been reached (S201: YES), the CPU 21 designates an ID via an e-mail instructing reservation of image data transfer via the LAN interface unit 25 and the LAN transceiver 20. A call is transmitted to the photographing apparatus 1 (S202).

  When the photographing apparatus 1 is left in a position where it can communicate with the LAN transceiver 20, the photographing apparatus 1 receives the calling of the photographing apparatus 1 transmitted from the storage device 2 by the LAN transmission / reception unit 109. When receiving a call from the storage device 2, the CPU 101 of the photographing device 1 transmits a response to the call from the LAN transmission / reception unit 109 to the storage device 2. When the imaging device 1 transmits a response to the call, the CPU 21 of the storage device 2 can receive a response from the imaging device 1 to the call via the LAN interface unit 25 and the LAN transceiver 20.

  After step S202 is completed, the CPU 21 waits for reception of a response from the photographing apparatus 1 (S203). If no response is received from the photographing apparatus 1 within the predetermined time (S203: NO), the CPU 21 determines whether or not the photographing apparatus 1 has been called a predetermined number of times (S204). If the shooting device 1 has not been called a predetermined number of times (S204: NO), the CPU 21 returns the process to step S202 and transmits the call of the shooting device 1 again. If the predetermined number of calls of the photographing apparatus 1 has already been performed (S204: YES), the CPU 21 ends the process. When the response from the photographing apparatus 1 is received in step S203 (S203: YES), the CPU 21 is designated by an e-mail instructing reservation of transfer of image data via the LAN interface unit 25 and the LAN transceiver 20. Transfer request information for requesting transfer of the image data is transmitted to the photographing apparatus 1 (S205).

  The CPU 101 of the photographing apparatus 1 receives the transfer request information by the LAN transmitting / receiving unit 109 (S206), searches the storage unit 111 for the image data specified by the received transfer request information (S207), and searches the searched image data for the LAN. The data is transferred from the transmission / reception unit 109 to the storage device 2 (S208). The CPU 101 may perform a process of deleting the transferred image data from the storage unit 111 after transferring the image data to be transferred.

  The CPU 21 of the storage device 2 receives the image data transferred from the photographing device 1 via the LAN interface unit 25 and the LAN transceiver 20 (S209), and stores the received image data in the storage unit 23 (S210). The process ends. Image data stored in the storage device 2 can be output to the outside in response to a request from a PC (not shown) connected to the storage device 2.
