Abstract
The present invention relates to image projection and provides a method and system for performing color calibration of light sources and correction towards a color target, for example a whitepoint target. The calibration and correction considers the ambient temperature and that the projector output has an arbitrary dimming level. The correction can be made automatic and can be performed by an operator in the field by pressing a button.
