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 20):
A moving picture coding apparatus which codes an input image to generate a bit stream, the moving picture coding apparatus comprising:\n a first coding unit which performs context adaptive binary arithmetic coding in which a variable probability value is used on, from 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, part of sao_type_idx indicating that the SAO is not to be performed; and a second coding unit which continuously performs bypass arithmetic coding in which a fixed probability value is used on, from among the multiple types of the SAO information, (i) sao_band_position indicating a range of pixel values to which the SAO is applied and (ii) sao_offset_sign indicating whether the offset value is positive or negative, wherein, in the bitstream, the coded sao_band_position and the coded sao_offset_sign are placed after the coded sao_type_idx, and wherein a variable probability is not used in the bypass arithmetic coding.
