La présente invention concerne un système (1) pour la commande d'une distribution de lumière d'un dispositif à projecteur (2) d'un véhicule automobile, comprenant un dispositif à projecteur (2) qui présente un système de lumière de pixel (3, 3'), un dispositif de détection d'une zone alentour (4) agencé dans une position pouvant être prédéfinie par rapport au dispositif à projecteur (2) et au moyen duquel une zone alentour du véhicule automobile peut être détectée, un dispositif d'analyse (5) en liaison de communication avec le dispositif de détection de zone alentour (4) et au moyen duquel les données du dispositif de détection de zone alentour (4) peuvent être analysées, à tout le moins dans quelle position les objets dans la zone alentour détectée du véhicule automobile se situent par rapport au dispositif de détection de zone environnante (4) ou par rapport au dispositif à projecteur (2), quel contour les objets présentent et de quelle catégorie les objets font partie, un dispositif de commande (6) qui est en liaison de communication avec le dispositif d'analyse (5) et qui est conçu pour commander la distribution de luminance pour le système de lumière de pixel, sur la base des données qui ont été transmises par le dispositif d'analyse (5) au dispositif de commande (6). Le dispositif d'analyse (5) est conçu pour transmettre au dispositif de commande (6), pour chaque objet pertinent identifié dans la zone alentour détectée du véhicule automobile, par rapport auquel une protection contre un éblouissement ou un marquage au moyen d'une lumière est nécessaire ou souhaité(e), les données concernant le contour de l'objet, la position de l'objet par rapport au dispositif de détection de zone alentour (4) ou au dispositif à projecteur (2) ainsi qu'une valeur de gradation pour l'objet.
