First Claim
1. A method, comprising:
- receiving, with a CPU, a frame of color image data comprising a plurality of input pixel values corresponding to a plurality of pixel positions in an image, wherein said input pixel values are represented as N-bit values, and wherein N>
1;
defining a plurality of color ranges with the CPU;
assigning, with the CPU, each of the pixel positions to one of the defined color ranges based on the pixel position'"'"'s input pixel value;
defining, with the CPU, a plurality of spatial binary patterns, wherein each spatial binary pattern is different from the other spatial binary patterns;
assigning each of the color ranges to one of the spatial binary patterns with the CPU; and
assigning, with the CPU, an output pixel value to each of the pixel positions, wherein the output pixel value for a given pixel position is representative of the spatial binary pattern assigned to the color range assigned to the given pixel position.

Abstract
A method and system operative to process color image data are disclosed. In one embodiment, the method can comprise the steps of receiving color image data, determining the color ranges to be applied to the color image data, assigning each of the pixel positions in the image data a color range, assigning a different spatial binary pattern to each color range, and assigning each of the pixel positions a binary output pixel value that corresponds to the spatial binary pattern assigned to the color range assigned to that pixel position. The resulting binary image data can be written to a file for subsequent storage, transmission, processing, or retrieval and rendering. In other embodiments, a system can be made operative to accomplish the same.
