Abstract:
In encoding an interlace picture in a field picture, a motion-vector detecting apparatus changes over a reference picture of a P-picture in a field unit, and changes over a reference picture of a B-picture in a frame unit. Moreover, in detecting the motion vector in different predictive directions, the motion-vector detecting apparatus simultaneously carries out a process of the same reference picture by changing over original picture frames.
