Abstract: An image decoding method capable of appropriately decoding an image by a simple configuration is an image decoding method for decoding an encoded image included in a bit stream block by block, and comprises: arithmetically decoding a block to be decoded (S101); determining whether or not the block to be decoded is located at the end of a slice (S103); when determining that the block to be decoded is not located at the end of the slice, determining whether or not the block to be decoded is located at the end of a sub unit that is an image constituent unit different from the slice (S105); and when determining that the block to be decoded is located at the end of the sub unit, performing termination processing of arithmetic decoding by arithmetically decoding a sub end bit (S106).

Abstract: An image coding method using arithmetic coding. The method includes: performing arithmetic coding on a first flag (greater1_flag) that indicates whether or not an absolute value of a target coefficient in a target coefficient block is greater than 1 (S701); and performing arithmetic coding on a second flag (greater2_flag) that indicates whether or not the absolute value is greater than 2 (S702). In the arithmetic coding on the first flag and the arithmetic coding on the second flag, it is determined whether or not an immediately-prior coefficient block that has been coded immediately prior to the target coefficient block includes a coefficient having an absolute value greater than a threshold value (S711). Based on a result of the determination, respective contexts to be used in the arithmetic coding on the first and second flags are selected (S712).
