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 (3) with a plurality ofblocks in the following field or frame of the video signal for deriving motion vectorsrepresenting the motion of the content of respective blocks between the first field or

frame and the following field or frame, a correlation surface is generated (3) forrespective blocks in the first field or frame, the correlation surface representing thedifference between the content of the block in the first field or frame and the content ofeach block in the following field or frame with which it has been compared, thecorrelation surface is tested (21, 22, 23) for a clear minimum, the size of the blocks isincreased (20) to generate new correlation surfaces, each new correlation surface istested (21, 22, 23) for a clear minimum, and motion vectors are derived (27) in dependenceon the clearest minimum so found.
