Motion prediction compensating device and its method |
摘要 |
An object of the invention is to provide a prediction compensation device and its method in which the processing efficiency of the overall coding process is enhanced. The address of an object pixel block serving as a pixel block of prediction object among a plurality of pixel blocks is detected, a first search range or a second search range narrower than the first search range is decided as the search range of a motion vector for the object pixel block on the reference frame according to the detected address, and the motion vector is searched for from the decided search range around the predictor of the motion vector based on the surrounding pixel blocks adjacent to the object pixel block.
