ABSTRACT:
A method and apparatus for identifying regions within a first binary image where half-bitting may be present, converting those regions to a multiple-bit/pixel representation so as to accurately represent the image density and the intended edge structure for the region, and further generating an enhanced resolution representation of the region in either a second binary image, wherein the second binary image has a spatial resolution greater than the first image, or a multiple-bit per pixel (gray) image at the same resolution as the input image so as to enable an improved rendering of the first binary image.
