Method of motion detection for 3D comb filter video decoder

摘要

A method of motion detection for a 3D comb filter video decoder is disclosed. In this method, a plurality of sampled data F_mP_x,y is obtained and temporarily stored after a composite video signal is sampled, wherein F_mP_x,y represents a sampled data of the y^th pixel on the x^th line of the m^th frame inside the composite video signal, and m, x, y are positive integers greater than or equal to 0. Then, F_m+1P_x,y, F_mP_x,y, F_m-1P_x,y, and F_m-2P_x,y are 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.
