FIG. 9 shows the procedure for formatting the card in this example. This format is basically the same as the format shown in FIG. 4, except that the selection of the management system (OS) in step S2 of FIG. 4 is the OS selection on the transfer side (step S2 ′) in this example. The configuration of the receiving personal computer in this example is the same as in FIG.

The processing on the receiving side (personal computer side) is shown in FIG.
As shown in, when the personal computer side is in the transmission mode, communication preparation processing such as modem setting and communication speed setting is performed (step S31), and waiting for a communication OK state (step S32), the transmitting side (camera side) ) Is instructed to start the transfer (step S33), and the received image data is recorded in the main memory (step S34).

File conversion on the camera side and the personal computer side in this example is performed as shown in FIG. 12, for example. On the camera side, the image file F1 and the display program file F2 are combined and transmitted as one file F. On the personal computer side, the received file F is divided to obtain the image file F1 and the display program file F2. Convert files.

Next, an example will be described in which, when transmitting recorded image data to another device, a plurality of images to be transmitted can be designated by a normal key operation.

In the conventional system as described above, the image file is selectively transmitted from the camera side by transmitting the image being reproduced as one image (file) by a key operation, or for management such as a control file. A plurality of information files are specified, and a plurality of images (a plurality of files) are transmitted continuously. However, it is difficult to specify a plurality of files by operating the keys because the number of keys is small in a device such as a camera, which is preferably small in size.

In this example, even a small device such as a camera having a small number of keys can easily specify a plurality of images and transmit continuous images. Manages multiple images by.

FIG. 13 is a flow chart showing the operation processing procedure of this example. In the transmission mode in which a plurality of images are designated and transmitted from the camera side, the reproduction operation (step S4
After 1), it is determined whether or not the right arrow switch 14D is operated (step S42). If it is operated, the next image is reproduced (step S44). If not, the left arrow switch is operated. It is determined whether 14C is operated (step S43). Here, if operated, the previous image is reproduced (step S45), and if not operated, it is determined whether or not the trigger 1 switch 14A is ON (step S46). Trigger 1 switch 14A is O
If it is not N, the process returns to the step S42, and if it is ON, the entry No. of the image being reproduced. Is obtained (step S47), and the entry NO. Is stored (step S48). Then, the trigger 2 switch 14B is turned on.
It is determined whether or not (step S49), if not ON, the process returns to step S42, and if ON, the transmission process is performed (step S50), and the process ends.

14 and 15 show flowcharts of the processing procedure of the image transmitting side device and the image receiving side device.
Referring to FIGS. 14 and 15, on the image transmission side (see FIG.
First, when recognizing that the modem is connected (step S51), it waits until the communication switch 14F is turned on (step S52), and sends a "communication request" command to the image receiving side (step S53). . On the other hand, the image receiving side (see FIG. 15) similarly recognizes the connection of the modem (step S71) and waits for confirmation of the reception of the "communication request" command from the image transmitting side (step S72). It is determined whether the reception operation can be normally performed (OK) (step S73). This decision is
Whether a memory card is inserted in the receiving device (for example, camera), the memory card is not protected, the memory card has sufficient free space, the memory card is formatted, etc. It is a judgment. If it is not OK in step S73, an NG command is transmitted (step S75), and the process proceeds to step S92.

When it is judged OK in step S73, an "OK" command is transmitted to the image transmitting side (step S74), and a telephone mark and a record "REC" are displayed on the LCD 18 shown in FIG. 1 (step S76). ).

When the image transmitting side confirms the reception of the "OK" command (step S54), the L of the camera concerned is returned.
The CD is turned on to display the telephone mark and the reproduction "PLAY" (step S55). Here, the user uses the left arrow switch 14C and the right arrow switch 14D to select the image to be transmitted. If it is determined that the "OK" command has not been received, the process proceeds to step S64.

Next, the "data transmission START" command is transmitted to the image receiving side (step S56). Upon receiving the "data transmission START" command (step S77), the image receiving side determines whether or not the size of the transmission image data file is larger than the receiving side memory card free space (OK) (step S78). If it is determined not to be OK, the "NG" command is transmitted (step S80), and the process proceeds to step S92. If it is determined to be OK, an “OK” command is transmitted to the image transmission side.

The image transmitting side confirms the reception of this "OK" command (step S57).
When the process proceeds to step S64 and reception is confirmed, data is transmitted, the LCD blinks (telephone mark blinks) (step S58), and the "data transmission end" command is transmitted (step S59). The image receiving side confirms the reception of the "data transmission end" command (step S83), and if not received, returns to the process of step S81.

On the image transmitting side, in step S59, after the "data transmission end" command is transmitted to the image receiving side, reception of the "retransmission request" command from the image receiving side is confirmed (step S60) and received. If so, the process returns to step S56. In step S60,
If you have not received the "Resend Request" command,
Confirm receipt of the "OK" command (step S61),
If not received, the process proceeds to step S64, and if the reception can be confirmed, the LCD is turned on (step S6).
2) It is determined that the communication switch 14F is "OFF", and if it is not "OFF", the process returns to step S56, and if it is "OFF", a "communication end" command is sent to the image receiving side ( Step S64).

The image receiving side confirms that the "communication end" command has been received (step S92). If it has not been received, the process returns to step S77, and if the reception is confirmed, an "OK" command is sent to the image transmitting side. Call (step S9
3) The LCD is turned off (step S94), and the process ends.

It is confirmed that the "OK" command transmitted in step S93 is received by the image transmitting side (step S6).
5) If it has not been received, the process returns to step S64, and if the reception is confirmed, the LCD is turned off (step S66), and the process ends.

On the other hand, when the image receiving side receives the "data transmission end" command transmitted from the image transmitting side in step S59, the received image is reproduced (step S84).
It is determined whether or not the left arrow switch 14C has been operated by the user to request retransmission (step S85). Here, if the switch is operated, the above-mentioned "retransmission request" command is transmitted (step S86), and the process returns to step S77. If not operated, the trigger 2 switch is in the "ON" state. Is determined (step S8
7). When the trigger 2 switch is in the ON state and reception is confirmed, it is determined whether or not there is sufficient free space (OK) in the receiving side memory card even after data recording (step S88). If it is not OK, the "NG" command is transmitted (step S91), and the process proceeds to step S92. If it is OK, an "OK" command is transmitted to the image transmission side (step S89). When the trigger 2 switch is not "ON", the right arrow switch 14C
It is determined whether or not is operated (ON) (step S8).
5) If it is not operated, the process returns to step S85. If it is operated, the received image is erased (step S96), and the process proceeds to step S88.

Next, examples of the present invention will be described. This embodiment achieves the same purpose as the example shown in FIGS. 13 to 15. By recording a plurality of image designations in a control file with a designated file name for DOS management, the file is managed. It is possible to specify a plurality of images without displaying the name on the image handling device (camera) and to easily and continuously transmit images.
