ABSTRACT:
In a special effects apparatus that processes an input video signal in accordance with a key signal representing an image pattern, a processing circuit processes the input video signal in accordance with the key signal and outputs a processed video signal which is stored in a video memory and fed back from the video memory to the processing circuit for further processing of the processed video signal in accordance with the key signal and the input video signal. A motion detection circuit detects motion of the image pattern represented by the key signal and a control circuit prevents the processed video signal from being stored in the video memory when the motion detector does not detect motion in the image pattern so that a desired soft-edged special effect can be maintained when there is no motion of the image pattern represented by the key signal.
