Abstract

Today, the desktop digital scanner has become a common office peripheral with applications diverse as clip art acquisition, character recognition and document management. With this increase in acceptance, the understanding of computer imaging has left the realm of black magic, known only by a select group of scientist and engineers, and entered into the mainstream of computer literacy. Competitive benchmarking articles in popular computer magazines no longer look at just the price of the scanner, how clear the user manual describes using the software that comes with it and if the technical support department of the manufacturer picks up the phone when they call. Today, simple tests based on sophisticated imaging concepts are employed to compare scanners whose published specifications would indicate that the same results will be achieved if the same target were scanned. These tests are all designed to provide a measure of the relative image quality between scanners. Manufacturers of desktop scanners need to be concerned not only with the image quality of their scanners compared to their competitors, but also the unit to unit consistency from their own production line. With the increase in end user understanding of imaging come in increase in expectations regarding scanner imaging performance
