Abstract
A compensation table compressing method is provided, processes each encoding block by prediction modes and select one prediction mode with the minimum rate distortion optimizing value as an optimized prediction mode by the rate distortion optimizing method such that each encoding block can correspond to an optimized prediction mode, which lowers the compression ratio of the compensation table and the time complexity of encoding and increases the quality of compression.
