摘要：In, for example, a motion compensated video standards converter (Figure 1)wherein blocks in a first field or frame of a video signal are each compared with a pluralityof blocks in the following field or frame of the video signal for deriving a plurality ofmotion vectors representing the motion of the content of respective blocks between the

first field 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 field or frame, pointed to by said plurality of motionvectors, and when there is a luminance mis-match between a pixel in an input field orframe and all the pixels, in the respective previous or following input field or frame,pointed to by the plurality of motion vectors, the respective motion vector is derived byluminance matching each pixel in an input field or frame with the pixels, in the respectivefollowing or previous field or frame only, pointed to by the plurality of motion vectors(Figure 33).
