Abstract: An image decoding method of decoding, on a per-block basis, a coded image included in a bitstream, includes: performing arithmetic decoding on a current block to be decoded (S101); determining whether or not the current block is at the end of a slice(S103); determining, when it is determined that the current block is not at the end of the slice, whether or not the current block is at the end of a sub-stream which is a structural unit of the image that is different from the slice (S105); and performing arithmetic decoding on a sub-last bit and performing arithmetic decoding termination, when it is determined that the current block is at the end of the sub-stream (S106).

Abstract: An image coding method using arithmetic coding. The method includes: performing arithmetic coding on a first flag (greater1_flag) that indicates whether or not an absolute value of a target coefficient in a target coefficient block is greater than 1 (S701); and performing arithmetic coding on a second flag (greater2_flag) that indicates whether or not the absolute value is greater than 2 (S702). In the arithmetic coding on the first flag and the arithmetic coding on the second flag, it is determined whether or not an immediately-prior coefficient block that has been coded immediately prior to the target coefficient block includes a coefficient having an absolute value greater than a threshold value (S711). Based on a result of the determination, respective contexts to be used in the arithmetic coding on the first and second flags are selected (S712).

Abstract: An image coding method for coding an image on a block-by-block basis, includes: selecting, for each of a plurality of sub-blocks included in a coding-target block and each including a plurality of coefficients, a context for performing arithmetic coding on a parameter indicating a coding-target coefficient included in the sub-block from a context set corresponding to the sub-block, based on at least one reference coefficient located around the coding-target coefficient, the coding-target block being a transform unit (S301); and performing arithmetic coding on the parameter indicating the coding-target coefficient using probability information about the selected context, wherein, in the selecting, the context is selected from the context set, the context set corresponding to a sum of (i) a value indicating a position in a horizontal direction of the sub-block in the coding-target block and (ii) a value indicating a position in a vertical direction of the sub-block in the coding-target block (S302).

Abstract: An image encoding method is used for encoding a current picture on a block-by-block basis and includes: generating a reference picture list by (i) assigning a reference picture index to a reference picture referable for encoding the current picture and (ii) including the reference picture assigned the reference picture index into the reference picture list (S1001); and encoding a current block included in the current picture with reference to a reference picture that is specified, from the reference picture list, for encoding the current block (S1002), wherein, when a reference picture belonging to a reference view different from a current view to which the current picture belongs has a chance of being referenced for encoding the current picture, the reference picture belonging to the reference view is added to the reference picture list in the generating (S1001).

Abstract: A moving picture coding apparatus (100) includes an intra-inter prediction unit (107) which calculates a second motion vector by performing a scaling process on a first motion vector of a temporally neighboring corresponding block, when selectively adding, to a list, a motion vector of each of one or more corresponding blocks each of which is either a block included in a current picture to be coded and spatially neighboring a current block to be coded or a block included in a picture other than the current picture and temporally neighboring the current block, determines whether the second motion vector has a magnitude that is within a predetermined magnitude or not within the predetermined magnitude, and adds the second motion vector to the list when the intra-inter prediction unit determines that the second motion vector has a magnitude that is within the predetermined magnitude range.

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).
