REFERENCE PICTURE DETERMINING METHOD, MOTION COMPENSATING METHOD THEREOF AND DEVICE THEREOF, CAPABLE OF REDUCING A CALCULATION WHILE INCREASING COMPRESSION EFFICIENCY BY USING PLURAL REFERENCE PICTURES

摘要

It discloses a kind of reference picture and determines method, motion compensation process and device. ;According to the present invention, the step of determining the reference picture for constituting the first part of the method for multiple pieces of reference picture of current image is multiple pieces of (a) block; (b) one in the reference picture that the remaining adjacent block by reference to picture is picture block selected by t has been determined is referred to, which is characterized in that it includes the steps that the reference picture of the determining rest block. Therefore, although compression efficiency is good, the complexity that coding and decoding calculates can be reduced.
