Abstract
A basic pattern generating unitgenerates a film grain basic patternin which the histogram of random noise is substantially the same as the film grain basic pattern information. The film grain basic patternis of (64×64) pixels and an area of (16×16) pixels is cut out and supplied to a multiplierStrength informationis generated based on film grain strength informationproduced on the encoding side and an average valueof a pixel value in the area of (16×16) pixels of decoded image information. The strength of basic patternis adjusted by this strength information. Film grain imagewhose strength is adjusted is added to the area of (16×16) pixels of the decoded image informationby an adderby the unit of pixel.
