Abstract
A light-emitting diode (LED) array illuminates different objects in, for example, a commercial environment. A camera captures an image of each object under different lighting conditions. Feedback is used by processing circuitry for each image to determine the lighting parameters of the LED array to obtain optimum lighting conditions and the lighting parameters stored. When a new object is illuminated, the lighting parameters for the object are retrieved and used. The lighting parameters may change dependent on ambient conditions, including lighting and time of day.
