Abstract

L'invention concerne un dispositif et un procédé de prise de vue photographique et de rendu avec effet 3D. Le rendu de photographies en 3D, p. ex. de photographies stéréoscopiques, nécessite habituellement des moyens techniques placés à proximité de la tête, tels que des lunettes ou des écrans spéciaux à champs de vision limités. Les méthodes utilisées ont pour but d'éviter de telles restrictions. Ce but est atteint grâce à l'utilisation de plusieurs appareils de prise de vue photographique superposés verticalement, au calcul d'un mouvement d'appareil photographique vertical, virtuel, périodique souple et lent, à partir des prises de vue obtenues, et au rendu de ces prises de vue sur un écran d'usage dans le commerce. L'effet 3D est obtenu du fait de la similitude entre le mouvement ainsi simulé et le mouvement vertical de l'oeil humain pendant la marche. Le procédé et le dispositif conviennent à l'affichage en 3D sur tous les appareils appropriés au rendu de séquences d'images, tels que des écrans d'ordinateur, des écrans de cinéma et des panneaux publicitaires électroniques. L'animation verticale n'est pas limitée au visionnement de prises de vue réelles, mais peut être également générée par le rendu d'angles de prise de vue virtuels correspondants de tous les modèles 3D.
