Motion dependent video signal processing

摘要

In, for example, a motion compensated video standards converter (Figure 1) blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the next succeeding field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the next field or frame, motion vectors are allocated to each pixel of each field or frame, the allocated motion vectors are checked to identify spurious motion vectors by comparing the allocated motion vectors with motion vectors allocated to adjacent pixels, and spurious motion vectors so identified are replaced (84 to 89) by motion vectors allocated to adjacent pixels.
