IMAGE PROCESSING APPARATUS, CONTROL METHOD, AND COMPUTER PROGRAM PRODUCT CAPABLE OF MINIMIZING CROSS-LINKAGE BETWEEN LINE SCREENS

摘要

An image processing apparatus comprises a dither processing device that applies dither processing to input image data to express halftone using line screens by increasing an area rate of the input image data and a controller that decreases the number of line screens and maintains a prescribed dropout width between the neighboring line screens when the area rate of the input image data increases and the dropout width falls below a prescribed level.
