Abstract
A motion vector detector includes a processor array having a plurality of processing elements arranged in a two dimensional array. Each of the processing elements includes storage elements for storing search window data of a reference frame and associated template block date of a current frame and a circuit for obtaining an absolute difference of the stored search window data and template data. Each processing element shifts the stored data to an adjacent processing element in a one-way direction on a data transfer path. The processing elements shift the stored search window data while holding the template block data. A displacement vector is calculated in each cycle of the shifting of the search window data by a summation unit receiving outputs of the processing elements in parallel. A comparison unit receives outputs of the summation unit to detect a motion-vector for the template block.
