Claim One:
1. An image-processing device which detects motion between plural input images for each of a plurality of blocks formed by dividing the input images, the device comprising: a searching unit searching a local motion vector from edge images of the plural input images for each of the plurality of blocks; a calculating unit calculating evaluated values for a plurality of the local motion vector individually found from the plurality of blocks; and a correcting unit correcting the plurality of local motion vectors on the basis of the evaluated values of the plurality of local motion vectors, wherein the correcting unit performs a relative evaluation between a local motion vector to be corrected and the neighboring local motion vectors using their evaluated values, and corrects a value of the local motion vector to be corrected using a value of a local motion vector that has a highest evaluation among the local motion vector to be corrected and the neighboring local motion vectors, one of the evaluated values is an accuracy of position adjustment which is obtained when a search source block is position-adjusted by using the local motion vector, in which the search source block is a block corresponding to a search source of the local motion vector among the plurality of blocks of the input images, another of the evaluated values is an edge amount included in the search source block, and when performing the relative evaluation, the correcting unit removes a local motion vector with the edge amount smaller than a threshold value from the local motion vector to be corrected and the neighboring local motion vectors, and ranks remaining local motion vectors according to their accuracy of position-adjustment.
