Abstract

[L'invention fournit un procédé de gestion de données d’image dans un système d’éclairage automobile (SYS), ledit système d’éclairage comportant au moins un module d’éclairage (HL[z]) destinée à la projection de faisceaux lumineux, lesdits faisceaux lumineux étant générées à partir de données relatives à la sélection d’au moins une image (I[x]), chaque image (I[x]) étant respectivement définie par une matrice (M[x]) comportant une pluralité de rangées R[k] horizontale ou verticales de pixels (P[i]), dans lequel chaque pixel (P[i]) est caractérisé par une valeur numérique (V[i]) liée à une intensité lumineuse dudit pixel (P[i]), ledit procédé déterminant si le pixel analysé (P[i]) est considéré comme un point d’inflexion significatif (PIS[i]) de l’image, de sorte à le transmettre à au moins un module d’éclairage (HL[z]), afin qu’il puisse projeter une image résultante (Ir[x]). L'invention fournit également un système d'éclairage automobile (SYS) pour mettre en œuvre les étapes d'un tel procédé. Figure pour l'abrégé : figure 6]
