Abstract:
1. A multi-bit halftone generator comprising: means adapted for receiving n-bit binary encoded image data, the encoded image data including a plurality of pixels having 2 means adapted for communicating data to an associated document processing device, which document processing device includes means for rendering a document having 2 means adapted for receiving data representative of a two-dimensional threshold array having at least 2 means adapted for selecting a foreground gray scale level and a background gray scale level unique thereto from the 2 dither means adapted for selectively populating each two-dimensional dither matrix for each received pixel in accordance with remaining (n−m+1) bits thereof in accordance with the threshold array; and means adapted for generating output image data corresponding to the encoded image data in accordance with each populated two-dimensional dither matrix wherein the output image is rendered with at least two distinct foreground and background gray scale level combinations of the 2
