In the transmission mode for transmitting, the reproducing operation (step S4)
After 1), whether or not the right arrow switch 14D is operated
Is determined (step S42).
Is reproduced (step S44), and if no operation has been performed,
Then, it is determined whether the left arrow switch 14C is operated.
A determination is made (step S43). Here, if operated
If the previous image has been reproduced (step S45),
If not, determine whether trigger 1 switch 14A is ON
(Step S46). Trigger 1 switch 14A is O
If it is not N, the process returns to step S42, and
, The entry number of the image being reproduced. And get
Step S47), the entry No. To remember
Step S48). Subsequently, the trigger 2 switch 14B is turned on
It is determined whether or not it is (step S49).
Returning to the process of step S42, if ON, the transmission process is performed.
(Step S50), the process ends. FIGS. 14 and 15 show the image transmitting side device and the receiving side.
The flowchart of the processing procedure of the receiving device is shown.
Referring to FIGS. 14 and 15, on the image transmitting side (FIG.
First), when it recognizes that the modem is connected
(Step S51), the communication switch 14F is turned ON
(Step S52), the “communication request” frame
Command is transmitted to the image receiving side (step S53). one
On the image receiving side (see FIG. 15),
The connection is recognized (step S71).
Wait for the confirmation of the "communication request" command (step
(Step S72), whether or not the receiving operation on the receiving side can be performed normally
(OK) is determined (step S73). This judgment is
Insert a memory card into the receiving device (for example, a camera).
Or the memory card is protected.
The memory card has sufficient free space,
Determine whether the card is formatted, etc.
It is. If it is not OK in step S73, the NG frame
Command (step S75), and the
Move on to processing. In step S73, it is determined that the state is OK.
The "OK" command to the image sender
(Step S74), a telephone mark is displayed on the LCD 18 shown in FIG.
And a record "REC" are displayed (step S76). On the image transmission side, the "OK" command
When the reception is confirmed (step S54), the L of the camera
Turn on CD and display phone mark and playback "PLAY"
(Step S55). At this point, the user
Image transmitted using the switch 14C or the right arrow switch 14D.
Select an image. Also, if an “OK” command has not been received
If it is determined that it is, the process proceeds to step S64. Next, a "data transmission START" command
Is transmitted to the image receiving side (step S56). Image reception
Side receives the “data transmission START” command.
Then (step S77), the size of the transmission image data file becomes large.
Is larger than the free space on the receiving memory card (OK)?
It is determined whether or not it is (step S78). Here, OK
If it is determined that the message is “NG”, an “NG” command is transmitted (step
Step S80), and proceeds to the process of step S92. Ma
If it is determined that the operation is OK, an “OK” command is displayed.
Send to the image transmission side. The image transmitting side receives the "OK" command.
The communication is confirmed (step S57).
Proceeding to step S64 and confirming reception,
Data, the LCD flashes (the phone symbol flashes),
Step S58) Send a “data transmission end” command
(Step S59). On the image receiving side, "Data transmission
Confirm the reception of the "end" command (step S83), and
If not, the process returns to step S81. On the image transmitting side, in step S59,
The `` Data transmission end '' command to the image receiving side.
After the "Resend request" command from the image receiving side
Is received (step S60).
The process returns to step S56. In step S60,
If you have n’t received the “Resend Request” command,
Confirm the reception of the "OK" command (step S61),
If not received, the process proceeds to step S64, and
If the communication is confirmed, the LCD is turned on (step S6).
2), determine that the communication switch 14F is "OFF".
If not “OFF”, the process proceeds to step S56.
Return, if “OFF”, “Communication end” command is displayed.
The image is sent to the image receiving side (step S64). On the image receiving side, the "communication end" command
Is received (step S92), and if no
If so, the process returns to step S77, and if the reception is confirmed,
An "OK" command is transmitted to the image transmitting side (step S9).
3) Turn off the LCD (step S94) and end the process.
Complete. The "OK" frame transmitted in step S93
Is received on the image transmission side (step S6).
5) If not received, return to the process of step S64
When reception is confirmed, the LCD is turned off (step
S66), the process ends. On the other hand, on the image receiving side, a scan is performed from the image transmitting side.
"Data transmission end" command transmitted in step S59
Is received, the received image is reproduced (step S84),
Since the user requests retransmission, the left arrow switch 14C is
It is determined whether or not the operation has been performed (step S85). here
When the switch is operated, the above-mentioned “Retransmission
Quest ”command (step S86), and
Returning to the process of step S77, if no operation has been performed, the
The "ON" state of the switch 2 is determined (step S8).
7). When the trigger 2 switch is on,
Confirmation that the data has been recorded on the receiving memory card.
Determine whether there is sufficient free space (OK) (step
S88). Here, if it is not OK, "NG" command
Is transmitted (step S91), and the process of step S92 is performed.
Move to If OK, an “OK” command is displayed.
The call is transmitted to the image transmitting side (step S89). Trigger 2 switch
Switch is not "ON", the right arrow switch 14C
It is determined whether or not has been operated (ON) (step S8).
5) If not operated, return to step S85
Delete the received image if it has been operated (step
S96), and proceeds to the process of step S88. Next, an eye similar to the example shown in FIGS.
DOS management to specify multiple images
Record the specified file name in the control file
Display and display the file name on the camera.
Multiple images can be specified without any

(Step S131), and enters the transmission mode. [0054] As described above, according to the present invention,
The directory number and the directory number of the image data to be transmitted
Or file name image specific informationOn the information recording medium.
A control that is a file set separately from the image file
Since it is stored collectively in a roll file,
Image data that is transmitted only by reading a file
Data can be identified and the transmission process can be simplified.
You. When setting image identification information,
There is no need to prepare different special equipment.
