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 digital image is captured by one or more compounds of the imaging system including a depth-sensing camera, 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-shaped projection pattern to reveal one or more black regions and one or more white regions of the digital image, and filter out black from the one or more black regions and white from the one or more white regions, and replace the filtered-out black and the filtered-out white with dark gray and bright gray, respectively, to sharpen the digital image.
