1. one kind is used for reading the method for film grain patterns at film grain simulation with raster order, comprising:

  • Through using pseudorandom number generator to produce side-play amount and the side-play amount of vertical direction of the horizontal direction of film grain patterns, confirm to be used to select the initial deviation post that reads of the sample of film grain patterns;

    Each display line for from one group of film grain blocks of said film grain patterns repeats the said initial deviation post that reads;

    AndEach display line for next group film grain blocks uses the different initial deviation posts that reads.
