MOTION ESTIMATION METHOD THROUGH AN ASYNCHRONOUS VARIABLE MOTION ESTIMATING RANGE CAPABLE OF IMPROVING PICTURE QUALITY BY THE EXPANSION OF A SEARCH RANGE

摘要

PURPOSE: A motion estimation method through an asynchronous variable motion estimating range is provided to expand a search range to an MVP(Motion Vector Predictor) direction during the use of an asynchronous search range.;CONSTITUTION: A search range is set up as an asynchronous type according to moving a search range into a motion vector predictor direction(S100). A macro block mode and a sub mode are set up in the search range(S200). The motion vector is predicted by the center value of sub macro blocks in a set mode(S300).;COPYRIGHT KIPO 2011
