ABSTRACT:
A reference frame block from a memory is supplied to a feature extraction circuit and a search frame block from a separate memory is supplied to a feature extraction circuit. Within the extraction circuits, the frame blocks are divided into minor blocks and the integration of all pixels for each minor block gives a matching element. A matching process with the matching elements from the extraction circuits provides a frame motion vector. Data division circuits divide the matching elements provided from the extraction circuits into odd- and even-field matching elements, and the matching process with the odd- and even-field matching elements provides odd- and even-field motion vectors. This eliminates the need for a feature extraction circuit when obtaining field matching elements.
