ABSTRACT:
A motion detector for detecting the occurrence of image changes between successive fields of video information includes a signal averager for averaging the video signal from two lines of video signal of one video field and a signal averager for averaging the video signal from three lines of video signal of a successive field. The two average video signals are coupled to comparing means which develops a motion indicating signal when the two average video signals differ.
