Paper Abstract

The brighter, more portable projectors that have emerged in recent years have driven an increase in opportunities to use projectors in well-lit rooms and to project images on objects other than special screens. However, the color and tone of color images projected under such diverse environments are subject to degradation due to the effects of ambient light and of the projection surface. Therefore, using color sensors to detect environmental effects, we developed WallShot, a technology for correcting the color and tone of a projected image. We validated the effect of the corrections through psychophysical experiments.
