CAMERA ARRANGEMENT FOR SENSING A STATE OF A VEHICLE WINDOW
摘要
<p>A camera system for detecting a state of a vehicle window pane is described, having at least the following: a camera having an image sensor for detecting a first radiation emitted by the vehicle surroundings and for outputting image signals; and a radiation source for emitting a second optical radiation. At least a portion of the emitted second optical radiation is detectable by the image sensor as a function of a state of the window pane. The camera system is set up in such a way that a state of the vehicle window pane is determinable on the basis of the image signals output by the image sensor during measurements in which the vehicle window pane is illuminated differently by the second optical radiation. For this purpose, an evaluation unit which determines a state of the vehicle window pane on the basis of the image signals output by the image sensor during the measurements may be provided to record the image signals and to ascertain a state of the window pane. Measurements may be carried out in particular when the radiation source is switched on or off.</p>
