1. A method for controlling a headlight system of a vehicle, comprising:
- reading in an aerosol signal representing a recognized intensity of an aerosol in a field of vision of a camera of the vehicle;
activating a change in a light emission in a lighting area ahead of the vehicle with an aid of the headlight system as a response to the aerosol signal;
reading in image information of an image of the camera;
performing at least one of providing a color indicator value for at least one partial section of the image of the camera, and providing a gradient indicator value that represents a difference in brightness, derivable from the image information, of different image areas of the image of the camera; and
determining an aerosol intensity value by using at least one of the color indicator value and the gradient indicator value to determine and provide the intensity of the aerosol in the field of vision of the camera of the vehicle as the aerosol signal.
