First Claim
Patent Images
1. A system to generate a continuous tone image from tagged binary encoded image, comprising:
- a pattern identifier generator to generate a pattern identifier value based upon a pattern of pixels around a pixel of interest;
an image type selector to generate an image type signal identifying an image context type in a pre-determined neighborhood of pixels around a pixel of interest; and
a contone value generator, operatively connected to said pattern identifier generator and said image type selector, to generate a contone value from said pattern identifier value based upon said image type signal.

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.
