Abstract
Generation of evaluation value information about a motion vector, extraction of candidates for the motion vector on the basis of the evaluation value information, and determination of the motion vector to be allocated from the candidates for the motion vector are performed. The possibility that a reference pixel a in a second frame is a candidate for a motion from a target point in a first frame is evaluated on the basis of pixel-value correlation information to generate an evaluation value table. A constant area is adaptively set around each of the target pixel and the reference pixel corresponding to each extracted candidate for the motion vector in accordance with the state of the continuity of a constant pixel value. The motion vector from the first frame to the second frame is allocated on the basis of the result of comparison between values calculated for the constant areas.
