Abstract:
1. An intelligent, energy efficient system for illumination, comprising: a first image sensor placed at a location in a spatial region to monitor a scene in a vicinity of the location where the first image sensor is placed, the first image sensor exhibiting low light intensity sensitivity and acquiring mega-pixel resolution image data corresponding to the scene monitored, the spatial region being not enclosed; a first controllable light source operatively associated with the first image sensor and mounted to illuminate a light-controlled area of the spatial region, the light source controllable to assume extended states of illumination including an extended state of low light intensity illumination of the light-controlled area and an extended state of high light intensity illumination of the light-controlled area, and the first controllable light source characterized by rapid speed of switching from the extended state of low light intensity illumination to the extended state of high light intensity illumination; video analytics responsive to the acquired mega-pixel resolution image data corresponding to the scene to detect motion of one or more blobs, to further detect an event in the scene based on the motion of the one or more blobs, and to provide detected scene information that is indicative of the event in the scene and that efficiently identifies when the extended state of illumination should be changed; and a first controller responsive to the detected scene information to deliver a light control signal to the first controllable light source to control the first controllable light source's extended state of illumination in accordance with the event detected by processing performed by the video analytics.
