Abstract: An image coding method includes: performing context arithmetic coding (S511) 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 (S512) 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.

Abstract: An image coding method includes performing: context arithmetic coding (S711) to consecutively code (i) first information indicating whether or not to perform SAO processing for a first region 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 except the first region; and bypass arithmetic coding (S712) to code other information after the first and second information are coded. The other information includes third information indicating whether the SAO processing is edge or band offset processing. In the performing of context arithmetic coding (S711), an initial bit value in a bit string of a parameter indicating a type of the SAO processing is coded as the first information. In the performing of bypass arithmetic coding (S712), a value of a next bit following the initial bit in the bit string of the parameter is coded as the third information.

The fixed number is greater than or equal to two.

Abstract: An image encoding method for encoding a multiview video is provided. The method includes: determining a maximum number of per-picture pixels (127) and a maximum buffer size (128) which corresponds to a maximum number of candidate reference images for use in a non-multiview coding, based on a level signal (126) representing a coding level with reference to a table (T1) (S101); calculating a maximum number of candidate reference views (129) for use in inter-view predictive coding using the maximum number of per-picture pixels (127), an image size of an input image (125), and a scale factor for use in multiview video coding (S102); and calculating an MVC maximum buffer size (130) corresponding to a maximum number of candidate reference images for use in multiview video coding, using the maximum number of views (129), and the maximum buffer size (128) (S103).
