A motion vector processor for compressing video signal.

摘要

A video signal compressor. includes apparatus (11-17) for generating motion vectors for respective blocks of video data. Ones of the motion vectors (other than those which provide (18) direction to co-located blocks in other frames) are determined to be candidates to conversion to vectors which do provide direction to co-located blocks. However, conversion is precluded (100,102) if the vector is determined to be correlated with one of the neighboring motion vectors. <IMAGE>
