Abstract
A movement detection circuit for detecting movement information of a luminance signal and movement information of a chrominance signal of a television signal comprises a first movement detection circuit for detecting the movement information of the luminance signal and a second movement detection circuit for detecting the movement information of the chrominance signal. The first movement detection circuit detects the movement information of the luminance signal based on two signals spaced by one frame period, and the second movement detection circuit detects the movement information of the chrominance signal based on two signals spaced by two frames periods.
