Abstract
A first motion detection circuit detects presence/absence of motion in an image on the basis of a composite video signal and an output signal of a frame memory. A three-dimensional Y/C separation circuit separates a luminance signal and a chrominance signal from the composite video signal by an inter-frame operation or an intra-frame operation on the basis of a motion signal output from the first motion detection circuit. A motion detection circuit detects presence/absence of motion in the image on the basis of the luminance signal output from the three-dimensional Y/C separation circuit. A synthesizing circuit synthesizes motion signals output from the first motion detection circuit and a second motion detection circuit. A three-dimensional noise reduction circuit reduces noise of the luminance signal output from the three-dimensional Y/C separation circuit by an inter-frame operation or an intra-frame operation on the basis of an output signal of the synthesizing circuit.
