Reference numeral 1006 denotes a display unit that performs various notifications to the user. Reference numeral 1007 denotes a key input unit that receives a key input from the user.

  FIG. 3 shows a sequence chart when the power is turned on by the user in the camera 101. FIG. 4 shows a flowchart realized by the system control unit 1005 of the mobile phone 102 reading out the program stored in the ROM 1003.

  When the power of the camera 101 is turned on, the mobile phone 102 detects the camera 101 (S301), and performs connection processing with the camera 101 (S302, M201). As a result, a wireless link is established between the camera 101 and the mobile phone 102, and the mobile phone 102 can directly communicate with the camera 101.

  Thereafter, when an image is photographed by the camera 101, the camera 101 transmits a photographing notification message (M202) including photographing distance information to the mobile phone 102. Here, the shooting distance information includes the depth of field indicating a range that can be shot as a clear image, and the focal length and F value (aperture value) of the lens mounted on the camera 101. Is included. Instead of the depth of field and the hyperfocal distance, distance information based on the number of subjects (a wide range when the number of subjects is large and a narrow range when the number of subjects is small) may be included. This can reduce the processing load on the camera 101 when the subject is recognized at the time of shooting but the depth of field and the hyperfocal distance are not calculated.

  When the mobile phone 102 receives the shooting notification message via the antenna 1001 and the wireless control unit 1002 (S303, M202), the shooting distance information included in the shooting notification message is stored in the RAM 1004. Then, a response request message is transmitted by broadcast to other communication devices (here, the mobile phone 103) existing within the distance corresponding to the stored shooting distance information (S304, M203). Here, the response request message is transmitted with the transmission power corresponding to the shooting distance information. However, instead of this, a response request message may be transmitted using a plurality of wireless systems (wireless LAN, Bluetooth, Zigbee, IrDA, etc.) having different communication ranges using wireless systems according to shooting distance information.

  When the mobile phone 103 receives the response request message (M203), the mobile phone 103 returns a response confirmation message including the identification information of the own device and information about the transmission destination of the image data to the mobile phone 102 (M204). Here, the identification information of the own device is the telephone number, mail address, user name, etc. of the mobile phone 103. The image data transmission destination information includes, for example, address information of the server 107 set in advance by the user in the mobile phone 103, and information such as a user name and a password for logging in to the server 107.

  When receiving the response confirmation message (S305, M204), the cellular phone 102 stores the identification information of the cellular phone 103 included in the response confirmation message in the RAM 1004. Further, the mobile phone 102 receives the image from the camera 101 and stores it in the RAM 1004 (S307, M205). Here, when an image cannot be received from the camera 101 within a predetermined time (NO in S307), the process returns to S303 and waits for an imaging notification from the camera 101 again.

  When receiving the image (YES in S307), the cellular phone 102 adds the identification information of the cellular phone 103 stored in the RAM 1004 to the received image (S308). Next, the mobile phone 102 performs connection processing with the wireless base station 104 (S309, M206). As a result, a wireless link is established between the mobile phone 102 and the wireless base station 104, and the mobile phone 102 can directly communicate with the wireless base station 104. Further, the mobile phone 102 performs connection processing with the DPF 106 via the wireless base station 104 (S310, M207). This connection process includes an authentication process such as login for uploading an image from the mobile phone 102 to the DPF 106.

  When the connection processing with the DPF 106 is completed (YES in S311), the mobile phone 102 transmits an image to which the identification information of the mobile phone 103 is added to the DPF 106 (S312 and M208). Further, the mobile phone 102 transmits an image transmission confirmation message to the camera 101 (S313, M209), and notifies that the image has been transmitted to the DPF 106.

  If the connection process with the DPF 106 has failed (NO in S311), the mobile phone 102 transmits an image transmission failure message to the camera 101 (step S315). Here, the case where the connection process fails is, for example, a case where the authentication process fails within a predetermined time.

  Furthermore, since the mobile phone 102 has acquired information on the transmission destination of the image data (here, the server 107) from the mobile phone 103 (Yes in S601), the mobile phone 102 performs a login process to the server 107 (S602). Thereafter, the mobile phone 102 transmits an image to the server 107 (S312).

  In this way, since the image data is also transmitted to the transmission destination designated by the user who is the subject of the image data, the image data can be easily shared with the user who is the subject of the image data.

  In the above-described embodiment, when the camera 101 captures an image, a response request message is transmitted from the mobile phone 102. However, the present invention is not limited to this, and a response request message may be transmitted from the mobile phone 102 after a predetermined time has elapsed since the camera 101 captured an image. Further, when a change in the position of the mobile phone 102 is detected, a response request message may be transmitted from the mobile phone 102.

  In the above-described embodiment, the camera 101 and the mobile phone 102 have been described as different devices. However, they may be integrated. In this case, the communication between the camera 101 and the mobile phone 102 described above may be replaced with wired communication between the modules in the apparatus.

  In the above-described embodiment, the connection process with the DPF 106 is performed in S310. However, when the mobile phone 102 attaches an image to an e-mail and transmits the image to the DPF 106, the connection with the DPF 106 is not performed. Try to connect. In such a case, it is confirmed in S311 that the connection with the mail server has been completed.

  In the above-described embodiment, the mobile phone 102 detects the mobile phone 103, but there may be cases where more mobile phones are detected. In such a case, the mobile phone 102 acquires image transmission destination information from each of the plurality of mobile phones, and transmits an image to each transmission destination. This process can be realized by repeating S601 to S315 of FIG. In this way, images can be easily shared with a plurality of users.
