Abstract
The motion detection circuit is so constructed that an interframe difference signal is passed through a horizontal direction LPF and a vertical direction LPF in cascade connection, and the interframe difference signal thus obtained is divided by the value obtained by mixing an edge signal of an image and the image level signal of the image by a mixing circuit, thus providing a motion signal.
