ABSTRACT:
A video composing system for producing special effects comprising two special effect circuits each of which includes: a video display, a write-in address generator, a read-out address generator responsive to special effect signals, and a depth data generator for generating depth data according to the read operation. Also included is an image mixer for mixing video signals received from the two special effect circuits and a comparator for comparing data received from the two special effect circuits and for producing a control signal based thereon. Taking into consideration the depth parameter produces more naturally appearing video images.
