ABSTRACT:
The present invention relates to an apparatus for simultaneously estimating a set of frame-to-frame motions between two frames and a set of field-to-field motions between two fields. The apparatus for simultaneously estimating both a set of frame-to-frame motions and a set of field-to-field motions, comprises: a first delay unit 1 for delaying a set of search area data of a first frame of the frames; a selection unit 3 for selecting a set of current reference data of a second frame of the frames or a set of previous reference data of the second frame; a motion estimation unit 4 for calculating a mean absolute difference between an output of a selection unit 3 and an output of the first delay unit 1; a second delay unit 2 for delaying a feedback reference data from the motion estimation unit 4; and a comparator 5 for receiving an output from the a motion estimation unit 4 and employing a mean absolute difference for each of the fields to produce a mean absolute difference, a motion vector and a prediction direction for each of the fields, and to produce a mean absolute difference and a motion vector for each of sets of the reference data contained in the second frame.
