Abstract

The invention concerns a camera system, especially a camera system in a camera-based analysis system and/or assistance system of a vehicle, comprising a camera with an optical beam path (12), which has at least one optical element to guide image information to a light-sensitive image sensor (14). At least one test beam (22) can be coupled into a transparent test element (30) arranged on the input side in front of beam path (12) and, depending on a degree of soiling of the test element (30), at least one partial beam (24) indicating soiling can be directed from the test element (30) onto a sensor (14a) to receive the partial beam (24) indicating soiling.
