METHOD OF MOTION ESTIMATION AND IMAGE PROCESSING APPARATUS USING THE SAME

摘要

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.

1. A method of motion estimation comprising:
obtaining at least two motion vectors of a block between frames in a plurality of frames; determining whether the at least two motion vectors of the block are converged; calculating dispersity of motion vectors of adjacent blocks of the block whose the at least two motion vectors are determined to be converged; and setting a size of a search range of the block based on the calculated dispersity of the motion vectors of the adjacent blocks.
