Abstract:
1. A motion vector detection apparatus, comprising: a base luminance value production section configured to produce, based on a luminance value of a predetermined one of pixels of a base block set in a base frame, a base luminance value of the base block; an effectiveness calculation section configured to calculate an effectiveness degree of each of the pixels of the base block based on luminance values of the pixels of the base block and the base luminance value; a correlation calculation section configured to calculate, based on the luminance values of the pixels of the base block, luminance values of pixels in a plurality of reference blocks set in a reference frame which correspond to pixel positions of the base block and the effectiveness degrees corresponding to the pixel positions of the base block, a correlation degree of the reference block with the base block for each of the reference blocks; a position acquisition section configured to acquire the position of that one of the reference blocks set in the reference frame which exhibits the highest correlation degree with the base block; and a motion vector calculation section configured to calculate a motion vector based on the position of the reference block acquired by said position acquisition section and the position of the base block.
