Abstract
PURPOSE: To control the contour compensation amount through scanning-speed modulation, by removing the noise amount, which has been superposed upon a video signal corresponding to magnetic-field strength, for the period of a synchronizing signal and by applying a DC voltage obtained by rectifying the detection signal to a gain control circuit for the control of the amount of the video signal.
