Sending 1g starts sending the requested transmission data, and when detecting the end position EOL of one line of image information in this sending (m data), the end position EOL of one line of image information is detected.
If 6 consecutive frames are detected) or 1 to 14, - the image data is not completed and there is no request to send the next transmission data, it is determined that the next frame transmission request has not been made due to the width edge of the system, etc. After the end mark of one part of the information EOLt transmission destination, it is interrupted and the next transmission data transmission request is received.
Send time filler (all 0' information) for a maximum of 5 seconds. If no transmission request is received after 5 seconds have elapsed, a transmission error is detected and a failure processing unit is notified.

信データＦ。FIG. 3 is an explanatory diagram of rounding to explain transmission control of the present invention. Figure 3 (A) explains the transmission status of each transmission data of image information, and Figure 3 (B) shows the contents of the transmission data. When the end position EOL in the data F1 is detected, it is determined whether or not there is next transmission data, and the next transmission data Fl in this example is
If so, the transmission data F is continuously transmitted. Also, transmission data F.

If there is no data, the transmission is interrupted at the EOL and a time filler is sent.When the next transmission data is requested by the W4 eyelid, etc., the data transmission starts from the point where it was interrupted. If the next transmission data is not requested to be transmitted due to an error, etc., the electronic image information will not be interrupted and the image will not be blurred, and data will not be retransmitted, so communication costs etc. can be reduced.
