    摘要: The present invention provides a method and apparatus for reading film grain patterns in a raster order in film grain simulation including establishing a pseudo-random starting position, repeating the pseudo-random starting position for each line of a group of film grain blocks, and using a different pseudo-random starting position for each display line of a next group of film grain blocks. In various embodiments of the present invention, the different pseudo-random starting positions are triggered by resetting at least one seed value of a pseudo-random number generator implemented to determine said pseudo-random starting positions.
