Title:
3D櫛形フィルタビデオデコーダ用のモーション検出方法
Document Type and Number:
Japanese Patent JP4488791
Kind Code:
B2
Abstract:
A method of motion detection for a 3D comb filter video decoder is disclosed. In this method, a plurality of sampled data FmPx,y is obtained and temporarily stored after a composite video signal is sampled, wherein FmPx,y represents a sampled data of the yth pixel on the xth line of the mth frame 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,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.
