Abstract
The methods and apparatus for lighting systems provide a camera integral to a particular image projection lighting device (IPLD) to capture the projected image from the particular IPLD. The captured image can then be sent over a communication system to the operator for viewing on a visual display device such as a computer monitor on a central controller. Using the captured image of the projected image as viewed upon the display device, the operator may then command using the central controller the focusing, position or other parameters of the projected image upon the stage or projection surface to the desired value. The captured image may also be used, such as by a central control system, to automatically, and without operator intervention, adjust parameters of the IPLD to desired values.
