Apparatus and method for detecting motion vectors.

摘要

A motion vector detector includes a first matching operational circuit (3) which detects correlation between an output signal of a reference block memory (1) and a search block memory (2) with integral-pel accuracy. A second matching operational circuit (4) detects correlation between an output signal of a reference block buffer memory (5) and a search block buffer memory (6) with less than or equal to half-pel accuracy. The first matching operational circuit (3) and the second matching operational circuit (4) are operated in parallel.
