Abstract: The moving picture coding method for coding an input image includes: converting a value of a first parameter into a first binary signal, the first parameter identifying a type of a sample offset process to be applied to a reconstructed image corresponding to the input image (S301); and coding at least a portion of the first binary signal through bypass arithmetic coding using a fixed probability (S302).

Abstract: In a method of video image encoding wherein input images are encoded, the values of a first parameter that identifies the type of sample offset processing that is applied in the reconstructed image corresponding to an input image are converted to a first binary signal (S301), and at least part of this first binary signal is encoded (S302) by bypass arithmetic encoding in which fixed probability is employed.

Abstract: A method for encoding an image in which an image is encoded for each block, including: a context-selection step (S301) in which, for each of a plurality of sub-blocks respectively including a plurality of coefficients, the sub-blocks being included in a block to be encoded, which is the conversion unit, a context for arithmetically encoding a parameter representing the coefficient to be encoded that is included in the sub-block is selected from a context set corresponding to the sub-block, on the basis of at least one reference coefficient located near the coefficient to be encoded; and an arithmetical encoding step (S302) for arithmetically encoding the parameter representing the coefficient to be encoded, using probability information of the selected context. In the context-selection step, a context is selected from a context set corresponding to the sum of a value showing the horizontal position of a sub-block within a block to be encoded, and a value showing the vertical position.

Abstract: Provided is an image encoding method that comprises: an SAO processing step (S141) in which SAO processing is carried out on a Y signal, a Cb signal, and a Cr signal that are included in a block that is a target for processing; a first flag encoding step (S142) in which a first flag (sao_merge_left_flag) is arithmetically encoded, said flag indicating whether an SAO parameter that indicates the content of the abovementioned SAO processing is the same for the block that is a target for processing and a block that is adjacent and to the left of the block that is a target for processing; and an SAO parameter encoding step (S144) in which the SAO parameter for the block that is a target for processing is arithmetically encoded if the SAO parameter for the block that is a target for processing differs from the SAO parameter of the block that is adjacent and to the left of the block that is a target for processing (Step (S143) relates to a case in which the SAO parameters do not differ). In the first flag processing step, the first flag for the Y signal, the Cb signal, and the Cr signal is arithmetically encoded using a single context.
