    Abstract: PROBLEM TO BE SOLVED: To realize a picture display method capable of reducing animation pseudo-contours sharply while maintaining all possible gradation property even when it is a part where greater animation pseudo-contours are generated in a picture display method which performs gradation display by the subfield method. SOLUTION: In this picture display method, when pixels are non-object pixels, a picture is displayed by converting gradation values of pixels into displayable gradation values and when the pixels are object pixels, a picture is displayed by converting the gradation values into a first gradation value which is the average value of n (n is an integer of 2 or more) pieces of gradation values which are selected from among displayable gradation values and by performing a first diffusion treatment which averages the first gradation value spatially and/or temporally using the n pieces of gradation values.
