Tile map based multi-level supercell screening |
摘要 |
This invention is a screening method. The input image is divided into a plurality of supercells. These supercells are divided into a plurality of individual cells. An expanded cell is defined larger than each of the individual cells. A map of an input gray scale tone to an output gray scale tone is defined for each pixel of the expanded cell. The screening takes place for each pixel of the input image. First the method determines a pixel of the expanded cell corresponding to the input pixel. Then the output gray scale tone corresponding to the pixel of the expanded cell is recalled.
