Fast motion estimating apparatus

摘要

A fast motion estimating apparatus including a merging unit which merges differences for respective basic blocks separated from a macro block to calculate differences for blocks of various sizes; and a best motion estimation block determining unit which determines blocks performing a best motion estimation according to the differences for the blocks of various sizes calculated by the merging unit, wherein it a fast motion estimating apparatus using image blocks of various sizes is implemented in real time even when an input picture has a standard definition format.
