<p><P>PROBLEM TO BE SOLVED: To provide a motion vector detection processing apparatus capable of reducing an operation amount for coding without degrading the efficiency of coding. <P>SOLUTION: A reduced image is generated by a reduced image generator, and a motion vector is detected from the reduced image by a reduced motion vector detector. Next, an error value between a block centering around a pixel point around the tip of the motion vector of the reduced image and a block to be processed is calculated by a peripheral error value calculator. A search area set for a pixel point with the smallest error value, and shifted from the tip of the motion vector of the reduced image in the direction of the pixel point is set by a search area setting unit, and matching is performed by original resolution within the search area to generate the last motion vector. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
