MOTION ESTIMATION METHOD AND MOTION ESTIMATION APPARATUS

摘要

PURPOSE: A motion estimating method and a motion estimating device thereof are provided to efficiently perform an operation according to an exploration pattern by processing a plurality of blocks in parallel according to the exploration mode. CONSTITUTION: A control unit(250) generates a shift enable signal, a selection signal, and a PEG(Process Element Group) enable signal by referring to the information of the first and second registers(230,240) according to a received command. A shift unit(260) outputs or shifts the reference data in an exploration area of a reference frame or outputs the reference data. A selecting unit(270) selectively outputs a part of the output data of the shift unit or outputs the entire data. A PE(Process Element) array(280) calculates the output data and current data in response to the PEG enable signal.
