STOCHASTIC HALFTONE IMAGES BASED ON SCREENING PARAMETERS

摘要

A method for processing an image includes a screen generator (31) which allows a user to define parameters (15) that determine the characteristics of a stochastic halftone screen (32). The screen generator (31) dynamically generates the screen (32) prior to an image processor (20) producing halftone image data (24) from the screen (32) and a supplied image (11). The screen generator (31) is based on an efficient parameterized algorithm whose parameters are selected to allow a user to easily customize a screen (32) that is suited for one of a wide range of reproduction processes.
