ABSTRACT:
A method and apparatus for color screening combines existing halftone pixel matrices into a super cell. Images of different intensities are displayed using such a super cell by selectively illuminating pixels in the super cell in an order that depends both on the illumination order of the original cells and a visitation order for the halftone cells that make up the super cell.
