Abstract
A special effect system for a video signal comprises a distance calculator for calculating a distance between any given picture element data stored in a video memory, and a predetermined straight line. Certain picture elements are to be relocated in the final image, depending on their distance from the predetermined straight line, to obtain a particular special effect. A function generator including a readable function memory receives the calculated distance data as a read address to the function memory, whereby the calculated distance becomes the effective parameter for generating the special effects. A read address to the video memory is produced by utilizing the output from the function generator.
