Abstract
A system and method for motion detection in a composite video signal is disclosed. These dimensional (horizontal, vertical and time) analysis is performed on actual picture element content to monitor variations therein. Vector generation, approximation and analysis gives information on picture element content for intra-field, inter-frame and inter-field signal processing. Additionally, noise immunity through selection of a convergence zone for the disclosed vector analysis is also provided. Control signals for further video signal processing are likewise generated.
