Abstract:
With an image coding method, when performing arithmetic coding on parameters corresponding to a current coefficient to be coded, a related parameter which is a parameter related to a value to be referred to for selecting a context is arithmetically coded per coefficient among the parameters corresponding to the coefficient, and unrelated parameters which are parameters unrelated to a value to be referred to for selecting the context are collectively arithmetically coded per coefficient subset among the parameters corresponding to the coefficients in the coefficient subset.
