ARITHMETIC CODING FOR INFORMATION RELATED TO SAMPLE ADAPTIVE OFFSET PROCESSING

This abstract first appeared for US patent application 19011909 titled 'ARITHMETIC CODING FOR INFORMATION RELATED TO SAMPLE ADAPTIVE OFFSET PROCESSING

Original Abstract Submitted

An image coding method includes: performing context arithmetic coding to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.
