The efficiency of arithmetic coding is improved. When both the maximum value and the minimum value of a base interval are included in a segment interval, no code is output because there is no need for identifying the base interval from other intervals. When only the minimum value of the base interval is included, the code of 0 is output because the code of 1 is necessarily output for the other interval. When only the maximum value of the base interval is included, the code of 1 is output because the code of 0 is output for the other interval. When neither the maximum value nor the minimum value is included, the code of 01 or 10 is output.
