Camera system, method for operating a camera system and sensor device of a camera system

摘要

The system (10) has a camera with optical path (12), which has an optical unit for conveying image information to a light sensitive image sensor (14). A testing ray (22) is coupled into a transparent test body (30) that is arranged before the optical path. A pollution indicative partial ray (24) is directed from the test body to a sensor (14a), which is arranged in an area of the image sensor, based on the pollution degree of the test body. An independent claim is also included for a method for operating a camera system.
