L'invention concerne des caméras vidéo 3D pour la prise et l'enregistrement d'images vidéo 3D, et des affichages vidéo 3D pour l'observation stéréo directe et sans lunettes de l'image 3D sur un écran vidéo de cet affichage vidéo. L'affichage stéréo comprend: un écran stéréo avec une matrice vidéo LCD transparente couleur pour la génération d'images d'écran de trames gauche et droite de paires stéréo horizontales pouvant être observées directement par un utilisateur. L'affichage stéréo comprend une matrice de diodes électroluminescentes avec un contrôleur de motif matriciel programmable des diodes électroluminescentes à allumer pour le rétroéclairage de cette matrice vidéo. La matrice de diodes électroluminescentes est disposée sur un actionneur automatique pour l'ajustement automatique de la distance entre cette matrice de diodes électroluminescentes et la matrice vidéo. L'affichage stéréo comprend un système de suivi optronique pour le contrôle vidéo des centres des pupilles des yeux de l'utilisateur et la génération de signaux de commande que l'on envoie vers ce contrôleur et cet actionneur automatique afin de générer automatiquement avec des diodes électroluminescentes et des condensateurs de pixels collimatés d'image d'écran, qui sont focalisés automatiquement et dynamiquement dans des zones focales ponctuelles déterminées de vision stéréo par les deux yeux de l'utilisateur de trames gauches et droites à un, deux ou trois angles de prise de vue de la paire stéréo. La caméra vidéo 3D comprend un objectif de trame gauche et un objectif de trame droite. Chaque objectif comprend au moins une ou deux ou trois ouvertures ou micro-lentilles devant lesquelles se trouve au moins un système optronique de prise de vue avec un prisme de division de lumière comportant des miroirs dichroïques et trois matrices photosensibles pour une prise vidéo à une trame de trames gauches et droites multicolores de couleurs rouge, bleue et verte. Des obturateurs électroniques et des dispositifs de calcul sont connectés à ces matrices, et sont également connectés en série des convertisseurs analogiques-numériques, des processeurs programmables numériques avec des codeurs, et des cartes de mémoire avec des supports numériques pour l'enregistrement vidéo de signaux vidéo numériques entiers. Lesdits obturateurs et dispositifs de calcul sont connectés à des processeurs vidéo, de même qu'un moniteur vidéo pour le contrôle visuel et la commande de la prise vidéo. Le résultat technique consiste en la création de tout un éventail d'affichages stéréo fin pour téléphones intelligents, tablettes, ordinateurs portables, ordinateurs de bureau, affichages stéréo au sol, muraux et portables et téléviseurs 3D pour une visualisation stéréo longue et pleinement confortable.
