Color correction of imageforprojection onto dome screen

Abstract

Image display using a dome screen or a spherical screen brings observers an immersive feeling. In such a system, however, accurate color reproduction is not easy because of the multiple reflection of projected light inside the dome. In this study, the multiple reflection characteristics are measured and modeled by a simple function. Based on the model, a simple color pre-correction method is proposed and its effectiveness is demonstrated through the experiments.
