MOTION VECTOR DETECTING APPARATUS AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a motion vector detecting apparatus capable of detecting a motion vector with an accuracy of decimal without increasing the power consumption and upsizing the circuit scale.

SOLUTION: The motion vector detecting apparatus includes a decimal accuracy motion vector detection section 104 and a motion vector detection control section 105 that detect a motion vector by using only pixel values stored in a searching region image data memory 102 in a decimal position image block comprising decimal position pixels located around integer position pixels included in an image block particularized by a motion vector with an accuracy of integer to select only the image block at decimal positions comprising decimal position pixels whose pixel values can be calculated and an image block at integer positions particularized by the motion vector with an accuracy of integer for searching objects.
