Title
(EN) AUTOSTEREOSCOPIC DISPLAY AND METHOD FOR DISPLAYING STEREOSCOPIC IMAGES
(FR) ÉCRAN AUTOSTÉRÉOSCOPIQUE ET PROCÉDÉ PERMETTANT D'AFFICHER DES IMAGES STÉRÉOSCOPIQUES
Abstract
(EN)
The invention relates to an autostereoscopic display for simultaneously displaying a plurality of more than two views, each of the views being visible from one of a plurality of viewing zones (21, 22, 23, 24, 25, 26), these viewing zones (21, 22, 23, 24, 25, 26) forming a connected observation area (20) in front of the display, the display comprising a pixel array (11), an optical grating (12), a tracking device (13) and a control unit (14), wherein the pixel array (11) comprises a plurality of subsets of pixels (1', 2', 3', 4 ', 5 ', 6'), each of the subsets corresponding to one of the viewing zones (21, 22, 23, 24, 25, 26), wherein the optical grating (12) can be laterally shifted by varying the optical grating (12), and wherein the control unit (14) is configured for varying the grating (12) depending on a tracking signal (15) received from the tracking device (13) and for activating the pixels (1', 2', 3', 4', 5', 61) de¬ pending on image data (16) and on the tracking signal (15), the control unit (14) being programmed for causing, under certain conditions, the optical grating (12) to be varied such that the observation area (20) is shifted together with the viewing zones (21, 22, 23, 24, 25, 26) into a lateral direction and for simultaneously changing an activation of the pixels (1', 2', 3 ', 4 ', 5 ', 6') by exchanging the images or image sequences reproduced by the pixels (1', 2', 3', 4', 5', 6'). The invention relates, furthermore, to a corresponding method for displaying stereoscopic images.

L'invention concerne un écran autostéréoscopique permettant d'afficher simultanément une pluralité de plus de deux vues, chacune des vues étant visible à partir d'une zone parmi plusieurs zones de visualisation (21, 22, 23, 24, 25, 26), ces zones de visualisation (21, 22, 23, 24, 25, 26) formant une zone d'observation connectée (20) en face de l'écran, l'écran comprenant une matrice de pixels (11), un réseau optique (12), un dispositif de repérage (13) et une unité de commande (14), la matrice de pixels (11) comprenant une pluralité de sous-ensembles de pixels (1', 2', 3', 4 ', 5 ', 6'), chacun des sous-ensembles correspondant à une des zones de visualisation (21, 22, 23, 24, 25, 26), le réseau optique (12) pouvant être décalé latéralement en faisant varier le réseau optique (12), et l'unité de commande (14) étant configurée pour faire varier le réseau (12) en fonction d'un signal de repérage (15) reçu du dispositif de repérage (13) et pour activer les pixels (1', 2', 3', 4', 5', 6') selon des données image (16) et le signal de repérage (15), l'unité de commande (14) étant programmée pour amener, dans certaines conditions, le réseau optique (12) à varier de telle sorte que la zone d'observation (20) se déplace conjointement avec les zones de visualisation (21, 22, 23, 24, 25, 26) dans une direction latérale et pour changer simultanément une activation des pixels (1', 2', 3', 4', 5', 6') en échangeant les images ou les séquences d'images reproduites par les pixels (1', 2', 3 ', 4 ', 5 ', 6'). L'invention concerne en outre un procédé correspondant permettant d'afficher des images stéréoscopiques.
