Abstract

L'invention porte sur une unité de commande (37), qui comprend une section de calcul de fonction de transfert (37-1) dans laquelle une image de test basée sur un signal de test destinée à être utilisée pour le réglage est projetée, et une fonction de transfert, après la délivrance d'un signal d'image en fonction du signal de test et du signal d'image photographiée délivré en sortie d'un appareil photographique pour photographier l'image de test projetée à une section de modulation de lumière pour moduler de la lumière devant être délivrée en sortie en fonction du signal d'image, est calculée. Une unité de filtre (38) traite la transformation de la caractéristique inverse de la fonction de transfert vis-à-vis du signal d'image.
