Motion detection method and its apparatus |
摘要 |
A motion detecting method and its apparatus are provided in which during block matching procedure for detecting the 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 also, 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. <IMAGE> |
