Motion vector search method and apparatus

摘要

A motion vector (MV) search method including: searching for an integer-pixel MV among integer pixels and choosing an integer pixel corresponding to the integer-pixel MV; searching for a half-pixel MV among half pixels around the chosen integer pixel and choosing a half pixel corresponding to the half-pixel MV; and searching, when the half pixel is chosen, for a quarter-pixel MV among only specified quarter pixels disposed between the chosen integer pixel and the chosen half pixel and around the chosen half pixel and choosing a quarter pixel corresponding to the quarter-pixel MV.
