Abstract

The circuit includes a motion detector including a first device for producing pixel motion signals, which have a first state for each pixel which is found to have moved and a second state for each pixel which is found to have been stationary, and a second device for correcting the pixel motion signals in order to produce motion values in such a manner that a state of a pixel which differs from matching states of adjacent pixels is ignored.
