Abstract:
A system for halftone processing is provided. The system includes a programmable halftone segmentation system having one or more programmable parameters to accommodate different input image parameters, such as different printer or scanner parameters, and configured to generate output control data as a function of image input data. A programmable output processor receives the output control data and the image input data and generates image output data that compensates for halftone regions in the image input data.
