Abstract
The invention relates to a method of lighting a road with a vehicle headlight, in which the projected light is modulated in response to the presence of any persons on the road. The method comprises the following operations: detecting in the road scene at least one person, pinpointing the location of the person in the road scene, creating on an imager a mask having dimensions and position corresponding to the person, and lighting the road through the imager, to create a projected shadow around the person. The invention also provides a headlight for performing this method and having a first light source towards the imager, and an electronic system for generating light-occulting masks on the imager.
