专利名称:Motion dependent video signal processing发明人:Clive H. Gillard申请号:US07/512278申请日:19900420公开号:US04998168A公开日:19910305
摘要:In, for example, a motion compensated video standards converter whereinblocks in a first field or frame of a video signal are each compared with a plurality ofblocks in the following field or frame of the video signal for deriving a plurality of motionvectors representing the motion of the content of respective blocks between the firstfield or frame and the following field or frame, a respective motion vector is derived,from the plurality of motion vectors for each pixel in each block of each input field orframe by luminance matching each pixel in an input field or frame with the pixels, in theprevious and following input fields or frames, pointed to by said plurality of motionvectors, and the respective luminance matches are checked against a threshold valuedetermined in dependence on the local frequency content of the picture correspondingto the video signal.
