Motion detection method and its apparatus

摘要

A motion detecting method and its apparatus are provided in which during a block matching procedure for detecting movement, error data in displacement between reference two-dimensional blocks and target two-dimensional blocks to be examined of a frame are calculated by a known manner and, in addition, a movement throughout the two-dimensional blocks is detected by summing up a series of the error data at each displacement point of the blocks and selecting the smallest of the error data sum.
