1. A system to generate a continuous tone image from tagged binary encoded image, comprising:
- a binary image to contone image converter to receive binary image data and to generate contone image data;
said binary image to contone image converter including a pattern identifier generator to generate a pattern identifier value based upon the received binary image data;
said binary image to contone image converter generating contone image data based upon an image context type the received binary image data and the generated pattern identifier value.

Abstract
A method and system reconstructs a contone image from a binary image by first tagging pixels to identify one of a multiplicity of image content types. The tag information and the pattern of bits surrounding the pixel to be converted to a contone value are used to reconstruct a contone image from a binary image. The pattern of bits in the neighborhood is used to generate a unique identifier. The unique identifier is used as the address for a lookup table with the contone value to be used wherein each lookup table corresponds to an image context type.
