Abstract: A lighting device for vehicles with a minimum of two light modules, each comprising a number of LED light sources for the generation of a first light function and a second light function. One light module is a basic light module and the other light module is a long-range light module. A first light source and a second light source are arranged in the basic light module, so that when the first LED light source is energized, a first partial light beam for the creation of a first light function is radiated. When both the second LED light source and the first LED light source are energized, a second partial light beam for the creation of a second light function is radiated. A first LED light source and a second LED light source may also be arranged in the long-range light module, so that when the first LED light source is energized, a first partial light beam for the creation of the first light function is radiated.

Abstract: The invention relates to a method and device for determining object property of an object with the aid of images that have been recorded with the aid of a camera. Further, the invention relates to a method for determining a calibration parameter for a stereo camera. For determining the object property of an object, the object is defined in a first image recorded with the aid of the camera. Further, the brightness of a defined object is determined. Each time after a preset time interval, a further image is recorded with the aid of the camera. The object is defined in each of the further images and each time, the brightness of the defined object of each image is determined. Dependent on the brightness curve, an object property is assigned to the object.

Abstract: The present invention relates to a method for the optical self-diagnosis of a camera system and to a camera system for carrying out the method. The method comprises recording stereo images obtained from in each case at least two partial images (2, 3) creating a depth image, that is to say a disparity map (5) given by calculated disparity values, determining a number of valid disparity values (6) of the disparity map (5), and outputting a warning signal depending on the number of valid disparity values determined. A device for carrying out such a method comprises a stereo camera (1) having at least two lenses (7,8) and image sensors, an evaluation unit and a display unit.
