Special effect system for video signal

摘要

A television video signal processing circuit for imparting to a television picture special effects includes special function generators and picture pixel distance calculating circuits which enable pixels to be rearranged to create a special effect such as the folding of a portion of the picture unto itself or the rolling up thereof with reference to a predesignated straight line. A brightness contrast control circuit alters the brightness information in certain portions of the picture to accentuate given regions thereof so that the image appears to the viewer as if it were three dimensional.
