Abstract

Deux cameras de television (21, 22) sont disposees de maniere telle que leurs objectifs (1, 2) se trouvent a une distance relative (d) correspondant a l'ecartement moyen des yeux. On obtient ainsi deux images, soit une pour l'oeil gauche et une pour l'oeil droit d'un spectateur, qui, apres transmission individuelle a l'oeil respectif du spectateur, font apparaitre au spectateur une image tridimensionnelle. Le procede et l'appareil pour sa mise en oeuvre conviennent aussi bien pour des images noir-blanc qu'en couleur.
