ABSTRACT:
A recursive filter for effecting noise reduction of video signals, sums current and delayed signals and includes a motion detector for detecting interframe image motion. Signal from the motion detector is stored to provide a history of image motion. A decoder coupled to the motion detector and also responsive to the stored motion history develops control sequences for scaling the signal contributions which form the recursive filter sums.
