Abstract
The color of a projected image is dynamically corrected by sensing the color of the surface onto which the image is projected before the image is projected, and/or sensing the color of the surface between frames of the projected image, and/or by sensing the projected image as it is displayed on the surface and comparing what is sensed to the original image. Corrections to the color of the projected image are then made based on the sensed information from the surface onto which the image is projected.
