Abstract

PURPOSE:To save the transmission capacity of a communication line by sending a picture from which undesired part caused from the combination of picture is eliminated prior to the transmission as its own picture.

The transmission pre-processing units 5a-5d eliminate undesired part caused by the combination among own pictures caught by the cameras 1a-1d, gives its own picture to the part required for the combination and eliminate the other part as a non-signal. A special effect device 6 superimposes outputs of a picture receiver 3d and the transmission pre-processing unit 5d to constitute the result into one pattern.
