In the image transmission using the D basic interface, since the amount of information that can be transmitted per unit time is limited, it is not possible to send a complete moving image, and in the conventional image transmission device, the frame is advanced. It was an image with a reduced number of frames. Therefore, when controlling the peripheral device on the image transmission side from the image reception side while observing the image, there is a problem in that detailed control cannot be performed because the tracking of the image is delayed. Further, since image compression is performed, the image may be slightly blurred, and there is a problem that a clear image cannot be obtained.
