Patent number: 8180490Abstract: A video imager may be used to measure the natural and/or artificial light levels in a space. The lighting estimates may be passed to a controller via a communication network. The lighting estimates may be in the form of actual radiance values, brightness, or other forms. The controller may determine if and which areas of the space require more light or if and which areas of the space have more light than required. Based on the lighting estimates, the controller may issue commands to turn on/off or dim/brighten the light from various ones or combinations of light sources in or around the space via actuators. The controller may also directly interface with the light sources.Type: GrantFiled: January 4, 2008Date of Patent: May 15, 2012Assignee: ObjectVideo, Inc.Inventors: Khurram Hassan-Shafique, Niels Haering, Soma Biswas, Alan J.
