Sensitivity and Image Quality of Digital Cameras

Image quality and sensitivity are important criteria when selecting a camera for machine vision. This paper describes how these quantities are defined and how they are measured. It is intended as a practical guide and the measurements can be done quite easily. Nevertheless, a thorough theoretical background is presented for the different tasks in keeping with the German engineer's saying "Es gibt nichts Praktischeres als eine gute Theorie" (there is nothing more practical than a good theory).
