Abstract

Procédé pour imager une scène dans l’espace à partir d’un vaisseau spatial, comprenant une acquisition d’une séquence de N images de ladite scène, avec un recouvrement partiel de la plage dynamique desdites images et avec des temps d’exposition réglés respectivement pour acquérir des images de la plus foncée à la plus claire, de façon à couvrir une plage dynamique largement supérieure à celle de chacune desdites images acquises. Voir figure 1.
