Television standards converters using motion vectors corresponding to correlation of horizontal and vertical pixel offsets

摘要: A television standards converter for converting an input digital video signal from one standard to another, comprises a first low-pass filter (35) filtering the signal, high-pass (36) filtered horizontally and vertically, plurality of parallel processing channels comprising respective circuits (43 58) determining pixel by correlation magnitudes range horizontal vertical offsets, second filters (59) resulting magnitudes, selector (62) each said motion vector corresponding maximum magnitude, temporal interpolator (FIG. 14) deriving interpolated fields or frames combining sample values offset vectors.
