MOTION VECTOR DETECTING APPARATUS AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a motion vector detecting apparatus for detecting a motion vector in relation to an interlace image with high accuracy by using a sequential search method.

SOLUTION: A candidate vector generating unit 12 has two kinds of searching patterns for searching a frame vector and a field vector, and one of searching patterns is selected according to a searching mode 21 to generate a candidate vector. A motion compensating unit 14, a degree-of-similarity calculating unit 15, and a search control unit 16 search the motion vector sequentially according to the searching pattern selected by the candidate vector generating unit 12. As the searching pattern for searching the frame vector, a searching pattern including at least one of positions of pixels in the same field as the searching center is used.
