Stage: PROBLEM TO BE SOLVED: To simplify processing and to reduce processing delay.SOLUTION: The encoding device (100) includes a circuit and a memory connected to the circuit, wherein the circuit encodes a plurality of coefficient information flags by context adaptive coding when the number-of-times-of-processing limitation of the context adaptive coding allows the plurality of coefficient information flags to be collectively subjected to the context adaptive coding, in a case where the remaining value of the coefficient is encoded by Golomb-Rice encoding and the number-of-times-of-processing limitation does not allow the plurality of coefficient information flags to be collectively subjected to context adaptive encoding, the circuit skips encoding of the plurality of coefficient information flags and encodes the value of the coefficient by Golomb-Rice encoding, and in a case where orthogonal transform is skipped, the circuit encodes the plurality of absolute value flags by context adaptive encoding, and in a case where orthogonal transform is skipped, the coefficient information flags include a flag indicating whether the coefficient is a positive value or a negative value.SELECTED DRAWING: Figure 56 (Grant)
