Abstract

L'invention fournit un procédé pour gérer les données d'image dans un dispositif d'éclairage automobile (10). Ce procédé comprend les étapes consistant à fournir un modèle d'image (1), à diviser le modèle d'image (1) en rangées ou en colonnes de pixels (2), à fournir, pour chaque modèle de rangée (2), une pluralité de segments linéaires, à caractériser chaque segment linéaire par deux valeurs, à compresser les données des segments linéaires et à envoyer les données compressées au module d'éclairage. L'invention fournit également un dispositif d'éclairage automobile (10) pour effectuer les étapes d'une tel procédé.Figure pour l'abrégé : figure 3
