Abstract
The invention relates to a camera arrangement for a vehicle, comprising a camera (12), wherein by means of the camera arrangement a brightness of the surroundings of the camera is determinable. The camera arrangement comprises a storage device (38) in which is stored at least one brightness reference value (34) capturable by the camera. This reference value (34) is correlated with a corresponding value (36) indicative of a photometric quantity measurable by means of a photometer (14) at this brightness. An evaluation unit of the camera arrangement is designed for comparing a brightness value determined by the camera with the brightness reference value (34). Furthermore, the invention relates to a method for calibrating a camera (12) and for operating a camera arrangement.
