ABSTRACT:
A video image processing system includes a decay processor provided in a signal path via which a video key signal is recirculated through a frame store. The decay processor includes a selector switch for determining which of a plurality of signal paths having different signal modifying characteristics is included in the recirculation path. The selector switch is controlled by a pseudo random sequence generator, thus providing novel visual effects.
