Color Balancing Experimental Projection Displays
Maureen Stone · Color and Imaging Conference · 2001
Experimental, tiled displays made of commodity projectors provide a relatively easy and cost effective way to explore “on the wall” viewing and interaction. To color balance the display, each projector must be characterized and mapped to a common gamut. Projectors with three imaging elements and three filters can be characterized by a simple extension to the monitor calibration model. However, projectors with a single micro-mirror array and a color wheel may include a “white printer” to increase the system luminance. This makes the characterization more complex.
