System and method for image halftoning adapted to use multiple error diffusion paths

摘要

The method involves storing decision tables (3) associated to image zones and comprising data (30) that represent decisions of processing function of determined traveling path of pixels. Each zone is processed successively block by block and traveling path of a block is recognized for adjusting error reports and modifying direction and coefficients of reports according to the orientation of the path. An independent claim is also included for a system for establishing a zone dithering for an image adapted for utilizing variants of stochastic screening path.
