摘要：
An image coding method includes coding first binary data indicating a first intra prediction mode and second binary data indicating a second intra prediction mode, wherein in the coding, a first context adaptive portion which is part of the first binary data and a second context adaptive portion which is part of the second binary data are coded by context adaptive binary arithmetic coding, a first bypass portion which is different part of the first binary data and a second bypass portion which is different part of the second binary data are coded by bypass coding, and coded data is generated which includes the first context adaptive portion, the second context adaptive portion, the first bypass portion, and the second bypass portion, the first bypass portion and the second bypass portion being included subsequent to the first context adaptive portion and the second context adaptive portion.
