A METHOD FOR ESTIMATING HIGH SPEED MOTION OF HDTV

摘要

A high-speed motion estimating apparatus for a high-definition television is disclosed including a sub-screen forming portion for forming and outputting sub-search areas and prediction blocks corresponding to the respective steps from an input reference image and prediction image; a motion estimating portion for obtaining and outputting a minimum average absolute error and motion vector having the minimum average absolute error corresponding to one sub-search area from the sub-screen forming portion in the respective steps; and a minimum average absolute error motion vector detecting portion for obtaining and outputting a final motion vector having the minimum average absolute error and minimum average absolute error in the respective steps, using motion vectors having the minimum average absolute error and minimum average absolute error which are the outputs of the motion estimating portion.
