摘要： 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 (S811) of coding a first set of blocks included in a first region sequentially based on first probability information; and a second coding step (S812) of coding a second set of blocks included in a second region sequentially based on second probability information. In the first coding step (S811), 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 (S812), the second probability information is updated depending on the first probability information updated in the first coding step (S811), before coding the first target block.
