Abstract: A registration error detection system applicable to a real-time registration correction system is proposed. The system detects registration errors by using live pictures. Conventional block-by-block pattern matching and a new technique that finds and rejects false detection errors are used. False errors are completely rejected based on picture characteristics, including the spatial-frequency component, chrominance component, pattern-matching value, and detecting-error value difference among blocks. The proposed system is examined with a computer-picture simulation system. It is confirmed that the system detects accurate (less equal 1 pixel/line) registration errors and rejects false detection errors completely. When the system is implemented into a digital large-scale integrated circuit (LSI), estimated detection time is about 200 msec. The system enables a real-time, fully automatic registration correction system.
