Abstract
A circuit for detecting motion of a color video signal includes serially-connected first and second frame memories for storing the video signal frame-by-frame. First and second difference video signals are produced which respectively correspond to the difference between the input and output signals of the first frame memory and the difference between the input and output signals of the second frame memory, whereupon first and second absolute values are generated in response to the first and second difference video signals, respectively. Such first and second absolute values are employed for detecting first and second correlation patterns of the first and second difference video signals, respectively, and then motion of the video signal is discriminated on the basis of the detected correlation patterns.
