Movement detection circuit for television signals.

摘要

Disclosed is a picture movement detection circuit for use for processing a color television signal, that is, a circuit for detecting temporal variations in chrominance signal level of a color television picture. A signal corresponding to the magnitude of an absolute value, an amplitude, or the like, of a difference or addition signal between frames or field of a modulated chrom- inence signal of a color television signal is obtained, and a low frequency component is extracted out of the thus obtained signal so that the extracted low frequency component is used as movement information of the picture.
