Abstract
A method and apparatus for detecting the motion of image in a television signal is intended for a decoder of a multiple subsampling transmission signal without an interframe aliased portion in a lower frequency region. In the method and apparatus for detecting the motion, a next-adjacent interframe difference signal, an immediate-adjacent interframe difference narrow-band signal and an immediate-adjacent interframe difference broad-band signal or compensated versions of these signals are combined with maximum-value selection circuits and a minimum-value selection circuit for selecting the maximum-value and minimum-value among these three sets of signals so that a proper motion signal is extracted from the transmission signal.
