Abstract
A method of motion estimation includes obtaining motion vectors of blocks in a plurality of frames corresponding to a block to be motion estimated, determining whether the obtained motion vectors of the blocks are converged by comparing the obtained motion vectors of the blocks, calculating motion vector dispersity of adjacent blocks of the block to be motion estimated in a state in which the motion vectors are converged, and setting a size of a search range so as to correspond to the calculated motion vector dispersity of the adjacent blocks.
