Lorsqu'une image télévisuelle, une image d'ordinateur ou une image animée (2 et 3) est captée, une section d'affichage (1) est ajoutée pour afficher les images droite et gauche dans une image tridimensionnelle. Un dispositif de photodétection est prévu dans la partie de l'émetteur dans laquelle l'image tridimensionnelle reproduite est affichée. Les signaux de communication à normes unifiées sont transmis par l'émetteur. Un récepteur reçoit les signaux, et l'obturateur à répartition dans le temps est actionné vers la droite et la gauche pour former l'image tridimensionnelle du type en temps partagé qui est vue en trois dimensions de par la parallaxe binoculaire. Par ailleurs, une image entièrement circulaire est formée par un appareil destiné au captage d'une image tridimensionnelle panoramique au moyen d'éléments d'imagerie linéaires ou d'un miroir conique.
