Title
(EN) ARTIFICIAL VISION SYSTEM
(FR) SYSTÈME DE VISION ARTIFICIELLE
Abstract
(EN) An artificial vision system including a visual prosthesis comprising an integrated circuit comprising a plurality of pixels, an array of electrodes connected to the pixels and configured to excite neurons in a retina, and one or more PV cells. The implant furthermore comprises a photodetector. The integrated circuit is configured to process signals from the photodetector to selectively activate the pixels.
(FR) L'invention concerne un système de vision artificielle comprenant une prothèse visuelle comprenant un circuit intégré comportant une pluralité de pixels, un réseau d'électrodes connecté aux pixels et conçu pour exciter des neurones dans une rétine, et une ou plusieurs cellules PV. L'implant comprend en outre un photodétecteur. Le circuit intégré est conçu pour traiter des signaux provenant du photodétecteur afin d'activer sélectivement les pixels.
