发明名称 VIDEO ENCODING/DECODING APPARATUS, AND METHOD AND APPARATUS OF ADAPTIVE OVERLAPPED BLOCK MOTION COMPENSATION USING ADAPTIVE WEIGHTS
摘要 PURPOSE: A video encoding/decoding apparatus, and a method and an apparatus for compensating adaptive overlapped block motion using adaptive weights are provided to adjust a weight, thereby setting an overlapped block motion compensation result to be closer to a pixel value of an original image. CONSTITUTION: An RBMC(x,y) calculator(211) calculates a residual signal RBMC(x,y) during block motion estimation. A DN(x,y) calculator(213) calculates the difference DN(x,y) between motion compensation blocks. An additional information updating/setting unit(215) updates and sets additional information for performing adaptive overlapped block motion compensation. An adaptive overlapped block motion compensator(217) performs adaptive overlapped block motion compensation.
