Halftone imaging with reduced dot isolation

摘要

An output halftone image is formed from an input image having a plurality of input image pixels. The output image is formed by processing the input image pixels with a halftoning process that incorporates a hard dot stability constraint. The halftoning process forces a determination to produce a dot for each of N output halftone image pixels following an output halftone image pixel dot that would otherwise be isolated, where N>=1.
