Abstract
(EN)
An apparatus includes a controller coupled to a stereoscopic image viewer. The stereoscopic image viewer includes a viewing lens, an image capture unit, and a plurality of light sources. The image capture unit is configured to capture image frames. The controller receives the captured image frames. The controller is configured to switch light output from one of the plurality of light sources to another one of the plurality of light sources if a corneal reflection in a captured image frame intersects a fixed reflection in the captured image frame.
(FR)
L'invention concerne un appareil comprenant un contrôleur couplé à visualiseur d'images stéréoscopiques. Le visualiseur d'images stéréoscopiques comprend une lentille de visualisation, une unité de capture d'images, et une pluralité de sources lumineuses. L'unité de capture d'images est configurée pour capturer des trames d'images. Le contrôleur reçoit les trames d'images capturées. Le contrôleur est configuré pour commuter une sortie lumineuse de l'une de la pluralité de sources lumineuses à une autre de la pluralité de sources ruineuses si une réflexion cornéenne dans une trame d'image capturée coupe une réflexion fixe dans la trame d'image capturée.
