Abstract
A system and method for measuring and then correcting the color response from multiple projectors or display devices so that the devices can generate a color response that is uniform. An area light sensor (such as a commodity camera) is used to measure the color responses of each display and then to derive a model of the color transfer function for each display using a pattern of predetermined areas or regions displayed on each display device.
