ABSTRACT:
The invention is directed to a method of 3-dimensional (3D) comb filter video decoder. The composite video signal is sampled to obtain multiple sampling data FmPx,y, which represents the ythpixel of the Xthline in the mthframe, in which m, x, y are positive integer. After using Fm+1Px,y, FmPx,y, Fm−1Px,y, and Fm−2Px,yto judge whether the composite video signal is the motion state or the still state. The motion detection is based on the composite video signal without separation of luma and chroma. As a result, the motion detection can be precisely judged.
