Claim Text:
1. A method comprising: converting an original image into an input image having a lower bit count per pixel, said input image having pixel error based on said lower bit count per pixel, said converting diffusing said pixel error of each pixel of said input image to adjacent pixels using an error weighting matrix, said input image and consuming less storage and data processing resources relative to said original image; receiving said input image represented in an input image matrix into an image path of a printing device; and processing said input image through said image path to produce an output image from said input image, said image path having storage and data processing constraints that prevent said image path from processing said original image, said storage and data processing constraints allow said image path to process said input image, and said processing comprising: said filter comprising a low-pass matrix filter, said reconstructing: said reconstructing producing pixels having a higher bit count per pixel relative to said lower bit count per pixel of said input image.
