Experimental, tiled displays made of commodity projectors provide a relatively easy and cost effective way to explor e 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 printre to increase the system luminance. This makes the characterization more complex. This paper will discuss char-acterization of both forms of projectors in the context of color balancing the Stanford Interactive Mural.
