Patent Number:	7206023
Title:	Image Projection Lighting Devices With Projection Field Light Intensity Uniformity Adjustment
Abstract:	A lighting system is disclosed comprised of a plurality of image projection lighting devices including a first image projection lighting device. The first image projection lighting device is typically comprised of a microprocessor and a camera. The microprocessor and/or a command from a central controller can cause the camera to capture a first image of the projection surface and can cause the first image projection lighting device to produce a projected light which substantially reduces the nonuniformity of light intensity on the projection surface from the plurality of image projection lighting devices.
