    • 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.
    • 提供了一种通过使用更合适的概率信息来提高编码效率的图像编码方法。 图像编码方法包括:第一编码步骤,基于第一概率信息,顺序地编码包括在第一区域中的第一组块; 以及第二编码步骤,基于第二概率信息顺序地对包括在第二区域中的第二组块进行编码。 在第一编码步骤中,根据要编码的目标块的数据,在对目标块进行编码之后并在编码下一个目标块之前更新第一概率信息。 在第二编码步骤中,在对第一目标块进行编码之前,根据在第一编码步骤中更新的第一概率信息来更新第二概率信息。
