Abstract:
A moving picture coding method includes: performing context adaptive binary arithmetic coding in which a variable probability value is used, on first information among multiple types of sample adaptive offset (SAO) information used for SAO that is a process of assigning an offset value to a pixel value of a pixel included in an image generated by coding the input image; and continuously performing bypass arithmetic coding in which a fixed probability value is used, on second information and third information among the multiple types of the SAO information, wherein the coded second and third information are placed after the coded first information in the bit stream.

Claim (Index 18):
A moving picture decoding method for decoding a coded image included in a bit stream, the method comprising:\n performing context adaptive binary arithmetic decoding in which a variable probability value is used on, from among multiple types of sample adaptive offset (SAO) information that are included in the bit stream and used for SAO which is a process of assigning an offset value to a pixel value of a pixel included in an image generated by decoding the coded image, part of coded sao_type_idx indicating that the SAO is not to be performed, sao_offset indicating an absolute value of the offset value; and continuously performing bypass arithmetic decoding in which a fixed probability value is used on, from among the multiple types of the SAO information, (i) coded sao_band_position having a fixed length of 5 bits indicating a range of pixel values to which the SAO is applied and (ii) coded sao_offset_sign indicating whether the offset value is positive or negative, the sao_band_position being decoded after the sao_offset_sign is decoded, wherein a variable probability is not used in the bypass arithmetic decoding.
