Title
(EN) A METHOD OF IDENTIFYING LIGHT SOURCES AND A CORRESPONDING SYSTEM AND PRODUCT
Abstract
(EN)

A lighting system including a set of lighting devices for lighting an environment that may be controlled by a method. The method may include receiving, from one or more image sensors (e.g. a RGB-D camera—W), an image signal including a sequence of images of the environment under different conditions of illumination and light reflection. The method may further include processing the image signal to provide a light source identification signal representative of light sources affecting the environment, and controlling the lighting devices as a function of the light source identification signal, and, possibly, of human occupancy and activity.
