Claim One:
1. A method for modifying an image comprising: (a) receiving an image having a first bit depth; (b) modifying said image to create a first modified image resulting in a second bit depth different than said first bit depth in such a manner that the higher frequency content with respect to the lower frequency content of said modified image is attenuated; (c) modifying said image to create a second modified image based upon said first modified image in such a manner to reduce lower frequency content of said image; (d) modifying said second modified image to create a third modified image in such a manner to attenuate low amplitude content with respect to high amplitude content of said second modified image; (e) modifying said third modified image based upon said first modified image to increase the amount of low frequency content of said third modified image; (f) applying a dithering technique to at least one of said image, said first modified image, said second modified image, and said third modified image.
