An automatic vehicle head lamp dimming system which includes an optical system and an imaging processing system. The optical system is configured to discriminate between head lamps and tail lamps and focus the light rays from the head lamps and tail lamps on different portions of a pixel sensor array. The optical system as well as the image processing system provides for relatively increased discrimination of head lamps and tail lamps of other vehicles and also enables the high beam head lamps of the control vehicle to be controlled as a function of the distance as well as horizontal angular position of other vehicles relative to the controlled vehicle.

Cette invention se rapporte à un système automatique conçu pour diminuer l'intensité lumineuse des phares d'un véhicule et comportant un système optique et un système de traitement d'images. Le système optique est conçu pour distinguer les phares des feux rouges arrière et pour focaliser les rayons lumineux des phares et ceux des feux rouges arrière sur différentes parties d'une mosaïque de pixels de détection. Ce système optique, ainsi que le système de traitement d'images, effectue une distinction relativement perfectionnée entre les phares et les feux rouges arrière des autres véhicules et permet ainsi la régulation des phares de route du véhicule commandé en fonction de la distance et de la position angulaire horizontale des autres véhicules par rapport au véhicule commandé.
