ABSTRACT:
Each of element processors arranged in correspondence to pixels of a template block and a search window block respectively includes an A register and a B register provided in parallel with each other for storing search window block pixel data respectively, and a T register for storing template block pixel data. Motion vector evaluation value calculation is performed through a first one of the A and B registers and the pixel data stored in the T register, while operated data is transferred to the second one of the A and B registers from the first one of the A and B registers in parallel with the calculation operation, for storing head search window block pixel data of a next search window. A motion vector is detected at a high speed in excellent coding efficiency.
