Moving picture coding method, the each processing unit of claim 2, which comprises one or more of the processing unit 1, the processing for converting the video signal in the spatial domain by a factor in the frequency domain, which includes a process of quantizing the coefficients in the frequency domain in comprises a transformation, quantization step, and a conversion, arithmetic coding quantizing step arithmetic coding the luminance CBF flag that indicates whether it contains the quantized coefficients in the execution processing unit of claim 2 (S704), and the arithmetic coding step, the first and whether the size of the processing unit 2 are the same, and a depending on whether the predetermined maximum size of the process unit 2 (S701), and determines the probability tables used for arithmetic encoding (S702, S703).
