MOTION PREDICTION METHOD OF AN IMAGE SIGNAL FOR SUPPLYING ACCURATE MOTION VECTOR INFORMATION ABOUT A BOUNDARY OF AN OBJECT HAVING RESPECTIVELY DIFFERENT MOVEMENT

摘要

PURPOSE: A motion prediction method of an image signal is provided to perform separation allocation of a motion vector about a reference block for allocating an accurate motion vector result.;CONSTITUTION: A pair of blocks having the maximum motion vector difference value is calculated. First and second motion vectors about a pair of blocks are obtained. The maximum motion vector difference value is compared with a motion vector differential critical value(S140). In case the maximum motion vector difference value is greater than the motion vector differential critical value, the current block is divided into a first motion vector and a second motion vector(S200). The first and second motion vectors are allocated.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (S110) Detecting a block matching based motion vector; (S120) Buffering a block; (S132) Analyzing a space; (S134) Analyzing parallel movement; (S136) Detecting a scroll text; (S138) Detecting a logo/subtitle(0motion); (S140) Performing block division?; (S150) Dividing a block ratio; (S200) Starting block division
