Zusammenfassung:A method includes the steps: a) capturing image of an environment surrounding a vehicle by a camera; b) determining an area of increased brightness in the image based on pixels having a brightness exceeding a predefined threshold; c) estimating position coordinates of a light source in the environment from the area of increased brightness; d) detecting a shadow of the vehicle in the image; and e) determining a type of the light source as a spot light source or a direction light source from the shadow, environment.
