Dither volume for cell location |
摘要 |
While a general large layer dither volume provides great flexibility in dither cell design, by decoupling different intensity levels, they are inefficient to access since each colour component requires the retrieval of a different bit from the volume. Therefore in a multi threshold dither volume for digital halftoning a contone colour image, in the form of an array of contone colour pixel values to bi-level dots, there is allocated for each dither cell location a fixed set of n thresholds defining n+1 intensity intervals within which said dither cell location is defined to be alternatively not set and set.
