Abstract
An electronic circuit includes a block determinator, a candidate selector, and a motion vector generator to perform motion estimation between images. The block determinator determines a current block corresponding to a current location on an image and candidate blocks corresponding to relative locations with respect to the current location for each recursion for blocks constituting the image. The candidate selector selects some of the candidate blocks. The motion vector generator generates a motion vector for the current block based on one reference patch which is determined from reference patches indicated by candidate motion vectors of the selected candidate blocks. At least one of the relative locations corresponding to the candidate blocks selected in a first recursion is different from each of the relative locations corresponding to the candidate blocks selected in a second recursion following the first recursion.
