Motion vector detecting apparatus for determining interframe, predictive error as a function of interfield predictive errors

摘要

A motion vector detecting apparatus adapted for detecting motion vectors in motion prediction of an interlaced moving picture comprised of sets of picture blocks consisting of a plurality of pixels. In the case of carrying out five motion predictive error calculations of motion vector from current frame to frame to which reference is made, motion vector from odd field of current frame to odd field of frame to which reference is made, motion vector from odd field of current frame to even field of frame to which reference is made, motion vector from even field of current frame to odd field of frame to which reference is made, and motion vector from even field of current frame to even field of frame to which reference is made, output results of accumulators for carrying out calculation of motion vectors for field are used as they are, thus to carry out calculation of motion vectors for frame at the same time.
