Abstract
PURPOSE: To receive the picture required for grasping the outline in a short time and obtain a good-quality picture by transmitting one-time shares of video signals plural times and receiving them to store the first-time signals and rewrite selectively the second-time signals and following signals.
CONSTITUTION: By the transmission command to terminal 20, transmission control unit 27 drives transmission memory unit 25 to store signals from cammera 24 in one- picture components memory 25, and these picture signals are transmitted together with a start signal and a synchronizing signal by transmission unit 26. In receiving, signals are demodulated and waveform-shaped by receiving unit 28 and are sent to receiving memory unit 29, and simultaneously, the start signal and the synchronizing signal are detected by synchronizing detection unit 31, and memory 29 is driven through receiving control unit 32 to read signals onto monitor 30. In the first-time receiving, noise is detected for every scanning line by noise detection unit 33, and the position of the scanning line corresponding to noise is stored in detection line memory unit 34. In the second-time receiving, the corresponding part of memory 29 is rewritten only for noise-mixed scanning lines stored in unit 34, thereby correcting the picture to a noiseless pitcure.
