Abstract
A special effect generating system processes first, second, and third video signals supplied respectively from first, second, and third video signal sources to produce an output video signal with special effects. At a plurality of points of time along a first time base, first control data indicative of positions of edges of a first image represented by the first video signal are generated and stored in a first memory. At a plurality of points of time along a second time base, second control data indicative of positions of a boundary between second and third images represented by the second and third video signals are generated and stored in a second memory. The first, second, and third video signals are combined into the output video signal based on the first and second control data stored in the first and second memories.
