Abstract
Disclosed is a MUSE decoder for a pixel signal sampled in accordance with Multiple Sub-nyquist Sampling Encoding (MUSE). An interframe interpolation circuit (142) applies a pixel signal Sg which is not subjected to noise reduction processing to an intrafield interpolation circuit (18') for motion picture processing through a signal line (L5). A pixel signal delayed, which is outputted from delay circuits (24a, 24b) is subjected to a required noise reduction processing by an adder 60. Since the intrafield interpolation circuit 18' receives the pixel signal Sg which is not subjected to the noise reduction processing, an adverse influence on a motion picture, which may be caused by the noise reduction, is prevented even in case that the delay circuits (24a, 24b) are shared for motion picture processing and still picture processing.
