Adaptive Color Conversion Algorithm for Projection System with Color Tuner

Abstract

We developed the new projector with the fourth new liquid crystal panel that controls the yellow light independently in UHP lamp. This projector has the relation between brightness and color reproduction based on the volume of yellow light. In this paper, we present a new color conversion algorithm for the projector. This algorithm controls the volume of yellow light and corrects color shifted pixels depending on image features. As a result, this algorithm achieves both high brightness and vivid color reproduction.
