1. A method for eliminating glare from objects by using a headlamp system of a motor vehicle, the method comprising:
a) determining positions of two objects, which reflect light emitted by a headlamp of the headlamp system, in a camera image produced by a camera of the headlamp system pointing at an area in front of the motor vehicle;
b) dimming, in sections, the light emitted by the headlamp and illuminating the area in front of the motor vehicle in such a way that the two objects and one region of the area in front of the motor vehicle, which is represented in the camera image by a connecting image section connecting the at least two objects to one another, are illuminated with reduced light intensity so that less light is reflected back from the at least two objects; and
determining, for each of the determined positions of the two objects, a distance between the headlamp and a respective determined position of one of the two objects,
wherein a light intensity with which light is emitted from the headlamp is reduced less when the determined distance is a greater distance from the headlamp than when the determined distance from the headlamp is smaller.
