1. An apparatus comprising: detection/reception logic to detect a digital image of an object, wherein the detection/reception logic is further to detect a pattern signal associated with the digital image; computation logic to measure a spread function relating to at least one of the digital image and an imaging system of the apparatus, wherein the computation logic is further to determine deconvolution of the spread function, and wherein the computation logic is further to compute a pre-shaping filter based on the deconvolution of the spread function; and application/execution logic to execute the pre-shaping filter to apply the pattern signal to the deconvolution of the spread function to obtain a pre-shaped projection pattern of the digital image, wherein the pre-shaping filter to filter-out black from one or more black regions and white from one or more white regions, and replace the black and the white with dark gray and bright gray, respectively, to sharpen the digital image.
