When operating camera systems different factors affect the components. In an industrial production environment all components may be affected by heat, dust or dirt, moisture, vibration or other mechanical stress. Whereas signal processing tends to run very reliably for the most part, it is often the signal processing equipment, such as cameras, lenses and lights which is exposed to production hazards. It is obvious that a lens that has not been focused correctly will only produce blurred pictures. But what about a camera that has been shifted – it can still deliver good pictures, but does not record what it should.
