ABSTRACT:
A method of motion detection for a 3D comb filter video decoder is disclosed. In this method, a plurality of sampled data FmPx,yis obtained and temporarily stored after a composite video signal is sampled, wherein FmPx,yrepresents a sampled data of the ythpixel on the xthline of the mthframe inside the composite video signal, and m, x, y are positive integers greater than or equal to 0. Then, Fm+1Px,y, FmPx,y, Fm−1Px,y, and Fm−2Px,yare used to determine a motion/still status of the composite video signal. Since the present invention performs the motion detection according to the composite video signal whose Y/C has not been separated yet, the present invention can accurately determine the motion level.
