Filed: 1988-03-11
Abstract: PURPOSE:To prevent mis-detection of a still picture as a moving picture due to the pattern of a picture by applying time spatial filter processing to a moving detection signal. CONSTITUTION:A moving detection signal detected based on an inter-frame difference signal of a digitized television signal is inputted and a time spatial filter 2 uses the both to apply filter processing in a direction of time and/or space.
