PURPOSE: An H.264/AVC encoder for lossless context adaptive binary arithmetic encoding and a context adaptive binary arithmetic encoding method for the encoder are provided to efficiently perform encoding in consideration of accurate statistical distribution between a residual image signal of lossless compression and a residual image signal of loss compression. CONSTITUTION: A DCT and a quantization processor(101) generate a differential signal based on a motion compensation predicting signal from an image frame. The motion compensation predicting signal is inputted from a motion compensator(103). The motion compensator adaptively applies a weighted value to a signal for performing motion compensation. The motion compensation predicting signal is generated through the application. |
