Abstract
A motion detector detects motion of pictures represented by a composite color television signal and generates a motion signal representing the detected motion of pictures. A spatiotemporal filter extracts a color signal from the composite color television signal. A subtractor subtracts the color signal from the composite color television signal and thereby generates a luminance signal. The spatiotemporal filter includes a spatial filter. A pass band of the spatial filler is varied in accordance with the motion signal.
