ABSTRACT:
A method and apparatus for digital halftoning provides evenly distributed intensity clusters within a halftone cell. Pixel illumination ordering is determined based on adjacency from a candidate pixel to other pixels already placed in the order of illumination. Separate head and tail intensity arrays are used so that pixel ordering proceeds from both the first and last illuminated pixels toward pixels in the center of the illumination order.
