32.1: Appearance-Consistent Projector Tolerant of Various Colored Projection Surfaces and Ambient Light

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, we developed WallShot™, a technology for correcting the color and tone of a projected image based on detected environmental effects by color sensor. We validated the effect of the corrections through psychophysical experiments.
