Exploiting Color Constancy for Compensating Projected Images on Non-white Light Projection Screen

摘要

The use of projectors in various applications and environments has raised the need to adapt the displayed image to the viewing display environment. The displayed image under bright light may appear with washed colors and attenuated contrast. Similarly, the appearance of the displayed image may be affected by the reflectance and the geometry of the projection screen. In this paper, we formulate the problem of the color correction using the model of the perceived image, by exploiting the color constancy concept. We demonstrate that the color constancy can be widely employed to make perceived images invariant to the viewing conditions and even to simulate appearances obtained in some desired environments. We verify through formal and empirical validations that the proposed methods significantly produce the desired colors. Our methods can be useful in some areas like camouflages and simulations.
