Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce variation in a calculation quantity while suppressing deterioration in coding efficiency in a following type motion vector detecting apparatus. SOLUTION: A motion vector detecting apparatus 100 is provided with: a plurality of block matching calculation devices 102; and a block matching calculation selecting device 101. The device 101 selects a block matching arithmetic calculation device 102 having the highest coding efficiency from among the plurality of calculation devices 102, using a permissible calculation quantity as a calculation quantity permissible in performing block matching calculation processing. The selected calculation device 102 executes block matching between an input image and a reference image, and detects a motion vector highly accurately. COPYRIGHT: (C)2007,JPO&INPIT
