Abstract

L'invention porte sur un procédé et un système d'éclairage d'une ou de plusieurs cibles dans une scène. Une image de la scène est acquise à l'aide d'un dispositif de détection qui par exemple peut utiliser un capteur infrarouge. A partir de l'image, un dispositif de commande  d'éclairage détermine une figure d'éclairage, de telle sorte que la figure d'éclairage correspond de manière adaptative à au moins une position de la cible dans l'image. La cible est sélectivement éclairée à l'aide d'un dispositif d'éclairage, selon la figure d'éclairage.
