摘要
An image coding method includes: performing Sample SAO processing on Y signal, Cb signal, and Cr signal which are included in a target block; performing arithmetic coding on a first flag indicating whether or not an SAO parameter, which indicates details of the SAO processing, of the target block is identical to an SAO parameter for a left neighboring block immediately left of the target block; and performing arithmetic coding on the SAO parameter for the target block, when the SAO parameter for the target block is different from the SAO parameter for the left neighboring block. In the arithmetic coding on the first flag, a single context is used to perform the arithmetic coding on the first flag for the luminance signal, the chrominance Cb signal, and the chrominance Cr signal.
