Abstract: Abstract An image coding method of coding an image on a per-block basis to generate a bitstream, the image coding method comprising: 5 performing arithmetic coding on a current block to be coded; determining whether or not the current block is at an end of a slice; determining whether or not the current block is at an end of a sub-stream when it is determined that the current block is not at the end of the slice, the sub-stream being a structural unit of the image 10 that is different from the slice; performing arithmetic coding on a sub-last bit indicating the end of the sub-stream and being different from the current block when it is determined that the current block is at the end of the sub-stream; performing arithmetic coding termination as first termination, which is triggered by the 15 arithmetically coded sub-last bit, when the sub-last bit is arithmetically coded; performing arithmetic coding termination as second termination, when it is determined that the current block is at the end of the slice; and performing arithmetic coding on an end-of-slice flag indicating whether or not the current block is at the 20 end of the slice, the end-of-slice flag being different from the sub-last flag, wherein, when the first termination is performed, same processing as the second termination is performed, wherein, in the determining of whether or not the current block is at an end of a slice, when it is determined that the current block is at the end of the slice, 25 the end-of-slice flag on which arithmetic coding has been performed indicates a predetermined value of 1, and wherein a value of 1 is restored by the arithmetic coding performed on the sub-last bit. -1 9420144_1(GHMatters) P99142.AU.1

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. Figure 42.

The method comprises: binarizing first and second components to generate first and second binary signals, respectively, the first component being one of a horizontal component and a vertical component which are included in the last position information, and the second component being the other of the horizontal component and the vertical component; coding first and second partial signals by first arithmetic coding, and coding third and fourth partial signals by second arithmetic coding different from the first arithmetic coding, the first and third partials signals being parts of the first binary signal, the second and fourth partial signals being parts of the second binary signal, wherein the first arithmetic coding is context adaptive arithmetic coding using a variable probability that is updated based on a coded signal, and the second arithmetic coding is bypass coding using a fixed probability; and arranging the coded first, second, third and fourth partial signals in a bit stream in this order. When the horizontal component is a maximum value for a size of the current block, the bits of the first partial signal are identical and when the vertical component is a maximum value for a size of the current block, the bits of the second partial signal are identical. - 99 8879495_1 (GHMatters) P94474.AU.1 (Start Binarize last position information S402 Code prefix part of X component S403 -N Suffix part included?

Abstract: Provided is an image decoding method that decodes, for each block, image data included in an encoded stream, and that comprises the following steps: a derivation step for deriving candidates for intra-prediction modes of which there are always at least two, the candidates being intra-prediction mode candidates used for intra-screen prediction of a decoding subject block; an acquisition step for acquiring an index from the encoded stream in order to specify one candidate from the derived intra-prediction mode candidates; a selection step for selecting on the basis of the acquired index one candidate, from the derived intra-prediction mode candidates, as the intra-prediction mode used for intra-screen prediction of a decoding subject block.
