ADAPTIVE MOTION ESTIMATION/COMPENSATION DEVICE FOR MB-BASED ILLUMINATION CHANGE AND METHOD THEREOF

摘要

An adaptive motion estimation/compensation device and a method thereof for MB-based illumination change are disclosed. If a macro block mode is determined as a newly designed P_L0_l 6x16_Mean by calculating the sum of an absolute difference, the motion estimation device CAB AC-codes the absolute difference between the pixel mean of a current frame and the pixel mean of a candidate pattern block and transmits the CABAC-coded absolute difference to a pertinent decoder. With the present invention, the transmission amount of the bit stream transmitted to the decoder for decoding can be minimized by maximizing corresponding compressing rate.
