Abstract

Il est proposé un dispositif électronique (100) comportant une unité d’illumination (200), une unité de capture d’image (300) et une unité de commande (400), ladite unité d’illumination comprenant une source lumineuse (201) et un élément optique (202), et étant configurée pour générer un motif référent (510) en sortie dudit élément optique, et ladite unité de commande étant configurée pour analyser une image capturée par l’unité de capture d’image. L’unité de commande est configurée pour identifier le motif référent généré par l’unité d’illumination dans l’image capturée par l’unité de capture d’image. On décrit également un procédé qui permet de vérifier la présence d’un élément optique au sein d’un tel dispositif électronique. Figure pour l’abrégé : Fig. 1An electronic device (100) is provided comprising an illumination unit (200), an image capture unit (300) and a control unit (400), said illumination unit comprising a light source (201) and an optical element (202), and being configured to generate a reference pattern (510) at the output of said optical element, and said control unit being configured to analyze an image captured by the image capture unit. The control unit is configured to identify the reference pattern generated by the illumination unit in the image captured by the image capture unit. A method is also described for verifying the presence of an optical element within such an electronic device. Figure for abstract: Fig. 1
