Abstract
An apparatus for estimating a half-pel motion comprising: a memory for storing motion-compensation errors in integer-pel positions; an address generator for generating an address of the integer-pel positions to the memory; an operator for receiving the motion-compensation errors from the memory, and calculating motion-compensation errors in the eight half-pel positions which are on the outskirts of the integer-pel position having a minimum motion-compensation error; and a comparator and half-pel motion vector selector for comparing the motion-compensation errors in the eight half-pel positions with the minimum motion-compensation error in the integer-pel position and selecting a position having a minimum motion-compensation error as a final half-pel motion vector.
