<p>The present invention provides a method and apparatus for reading film grain patternsin a raster order in film grain simulation including establishing a pseudo-randomstarting position, repeating the pseudo-random starting position for eachline of a group of film grain blocks, and using a different pseudo-random startingposition for each display line of a next group of film grain blocks. In variousembodiments of the present invention, the different pseudo-random startingpositions are triggered by resetting at least one seed value of a pseudo-random numbergenerator implemented to determine said pseudo-random starting positions.</p> |
