AREA EXPANSION APPARATUS, AREA EXPANSION METHOD, AND AREA EXPANSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an area expansion apparatus, an area expansion method, and an area expansion program which can reduce an area to be subjected to image area expansion associated with motion compensation, and reduce a consumed power. SOLUTION: The area expansion apparatus includes; a subtractor 804 for subtracting a logical start address 803 of a pixel that is located at the upper-left corner of a reference block from a logical address 802 that successively indicates all pixel data in the reference block; and a converter 805 for converting an obtained address into a physical address 806 with referring to a predetermined table, and reads a pixel from a memory 807 in accordance with the obtained physical address 806.
