Abstract:
An image coding method for improving coding efficiency by using more appropriate probability information is provided. The image coding method includes: a first coding step of coding a first set of blocks included in a first region sequentially based on first probability information; and a second coding step of coding a second set of blocks included in a second region sequentially based on second probability information. In the first coding step, the first probability information is updated depending on data of a target block to be coded, after coding the target block and before coding a next target block. In the second coding step, the second probability information is updated depending on the first probability information updated in the first coding step, before coding the first target block.

Claim (Index 16):
An integrated circuit that decodes an image having a plurality of blocks, said integrated circuit comprising\n decoding circuitry which, in operation, decodes the blocks sequentially based on probability information indicating a data occurrence probability, wherein said decoding circuitry updates the probability information depending on data of a first target block to be decoded among the blocks, after decoding the first target block and before decoding a second target block to be decoded next among the blocks, and wherein said decoding circuitry decodes a third target block in the blocks based on the probability information (i) which is updated depending on the data of the first target block, the first target block being a neighboring block above the third target block and (ii) which is not updated depending on the data of the second target block, and wherein the third target block (i) is located on a left end of the image, (ii) is different from the second target block, and (iii) is decoded after decoding the first target block.
