Projectors and Dome Effective Contrast

Projectors and Dome Effective Contrast white paper

"Projectors and Dome Effective Contrast" by Claude Ganter, presented at IPS 2012.

This paper examines the interaction between video projectors native contrast and dome gain. A “fill factor” is introduced in order to characterize the type of scenery. The mathematical theory behind the computation of the integrated projectors and dome contrast is explained. Finally, simulations of dome original images will be shown in order to serve as a visual guide for selecting the best projection parameters with new planetariums installations.
