Abstract
Visitors cannot always view objects displayed in the cases in most museums as well as desired because of light reflecting from the glass. Not only their fade color but also highlights of the glass in the showcases make studying them in detail difficult. We present an overlapped multi-projection display system for creating a high-color appearance onto the surface of an object. Our system can also be used to compensate for the distortion caused by the reflection. Such as system is suitable for compensating for the distortion caused by the maximum color and brightness of images presented with conventional projectors. To reduce the loss of quality caused by the highlights, each projector automatically excludes the specular direction area, and then another projector complements the exclusion. Using this combined approach expands the range of the colors that can be reproduced and reduces the detrimental effect of the brighter area. We introduce overlapped multi-projection and show experimental results for when the appearance of the color of regular gradation patterns was changed and the appearance of a painting that had naturally degraded. Our method can be applied to all types of projection onto screens that do not have a matt surface.
