Abstract

Dispositif de classification d’une source lumineuse La présente invention concerne un dispositif de classification (14) d’une source lumineuse (11) comprenant : - un capteur (20) propre à recevoir un flux lumineux émis par une source lumineuse (11), le capteur (20) comprenant une pluralité de pixels regroupés en ensembles, chaque ensemble comprenant un premier pixel et un deuxième pixel, adjacent au premier pixel, chaque premier pixel étant propre à générer un premier signal relatif à une première portion de flux lumineux dans une première bande spectrale reçue par ledit premier pixel, chaque deuxième pixel étant propre à générer un deuxième signal relatif à une deuxième portion de flux lumineux dans une deuxième bande spectrale reçue par ledit deuxième pixel, - un calculateur (24) configuré pour comparer le premier et le deuxième signal et pour classifier la source lumineuse d’émission (11) en fonction du résultat de la comparaison.
