Title
(EN) SENSOR FOR DETECTING GLARE CONDITIONS
(FR) CAPTEUR POUR DÉTECTER DES CONDITIONS D'ÉBLOUISSEMENT
Abstract
(EN) A sensor and/or system controller may process an image multiple times at multiple resolutions to detect glare conditions. A glare condition threshold used to determine whether a glare condition exists may be based on the resolution of the image. When the resolution of the image is higher, the glare condition threshold may be higher. The sensor and/or system controller may organize one or more adjacent pixels having similar intensities into pixel groups. The pixel groups may vary in size and/or shape. The sensor and/or system controller may determine a representative group luminance for the pixel group (e.g., an average luminance of the pixels in the group). The sensor and/or system controller may determine a group glare condition threshold, which may be used to determine whether a glare condition exists for the group of pixels and/or may be based on the size of the group.
(FR) La présente invention concerne un capteur et/ou un dispositif de commande de système qui peuvent traiter une image de multiples fois à de multiples résolutions pour détecter des conditions d'éblouissement. Un seuil de condition d'éblouissement utilisé pour déterminer si une condition d'éblouissement existe ou non peut être basé sur la résolution de l'image. Lorsque la résolution de l'image est plus importante, le seuil de condition d'éblouissement peut être plus important. Le capteur et/ou le dispositif de commande de système peuvent organiser un ou plusieurs pixels adjacents présentant des intensités similaires en groupes de pixels. Les groupes de pixels peuvent varier en taille et/ou en forme. Le capteur et/ou le dispositif de commande de système peuvent déterminer une luminance de groupe représentative pour le groupe de pixels (par exemple, une luminance moyenne des pixels dans le groupe). Le capteur et/ou le dispositif de commande de système peuvent déterminer un seuil de condition d'éblouissement de groupe, qui peut être utilisé pour déterminer si une condition d'éblouissement existe pour le groupe de pixels et/ou peut être basée sur la taille du groupe.
