IMAGE PROCESSING APPARATUS, ENCODER AND METHOD FOR THEM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of generating a motion vector with a computing amount less than that of conventional one.

SOLUTION: A motion vector generating circuit 34 generates a difference between pixel data of image data S23 as to a plurality of pixel positions in a block of a processing object and pixel data of image data S31 corresponding to the pixel positions obtained by using an object motion vector, and selects the object motion vector by performing a first processing wherein the differences obtained as to a plurality of the pixel positions are accumulated and an accumulated value is generated. A residual arithmetic control circuit 35 terminates the first processing when discriminating that a result of accumulating the differences as to part of pixel positions among a plurality of pixel positions obtained during execution of the first processing is greater than a minimum accumulated value having already been obtained by the first processing using other object motion vector.
