MOTION VECTOR DETECTOR

摘要

PURPOSE:To obtain the motion vector detector with a small occupied area, low power consumption and at a high speed operation. CONSTITUTION:A motion vector detector includes a processor array (10) in which element processors storing search window data and template data are arranged in a shape of 2-dimension array. Each of the element processors included in the processor array (10) is provided with a function taking a difference absolute value of the search window data and template data stored and with a function shifting storage data to an adjacent element processor. The motion vector detector includes a total sum section (12) summing the total of the difference absolute values outputted from each element processor of the processor array (10) and a comparator section (3) detecting a motion vector with respect to the template block according to the output of the total sum section (12).
