Abstract
A motion sequence pattern detector detects a periodic pattern of motion sequences within a succession of video fields, such as film mode or progressive scan mode and comprises a motion detector for detecting the presence of motion from increment to increment within predetermined increments of the succession of video fields and for thereupon putting out a first motion detection signal for each said increment, and logic circuitry responsive to the first motion detection signal for detecting the periodic pattern of motion sequences within the succession of video fields.
