Abstract

The invention relates to a camera system (1) for vehicle applications, designed to be mounted behind a windscreen (8) of a vehicle and comprising the following: at least one optical system (2) for imaging electromagnetic radiation; at least one image sensor (3) for detecting the imaged electromagnetic radiation and converting it into electrical signals; and an evaluation unit (4) for processing the electric signals. The invention is characterised in that the camera system also comprises the following: a controllable light source (6) for generating electromagnetic radiation for an optical test of the camera system, and an electronic testing system (5) for evaluating the electric signals converted by the image sensor and for controlling the light source. The camera system is also designed such that the electromagnetic radiation generated by the light source is imaged onto at least part of the image sensor by means of the at least one optical system, and the electronic testing system evaluates the electrical signals generated by the image sensor in this way for operational readiness and for definition of functional values of the camera system.
