Abstract

The goal of this paper is to simulate the essential process that happens during the scanning of an image. We begin with the scanning of an image. We use a lens that collects the reflected light and then the scanned image is acquisitioned by the CCD sensor. The optics of the scanner introduces the falloff of the irradiance at the edges of the detector. Then we filter the blur introduced by the optics of the scanner and we filter the photon shot noise. At the end of scanning we obtain a halftone image. We correct the halftone image and we JPG compress the image. Finally, the image is saved and then is reproduced on the display.
