Multiplex Image Projection Using Multi-band Projectors

In this paper, we propose a novel image representation method by using multi-band projectors. In this image representation method, each observer, such as human, camera and other sensors, can perceive different images from each other, even if the image projected from the projector is identical. For this objective, we encode multiple images into a single image by using the difference of spectral sensitivity of each observer, and project it by using the multi-band projector. The projected image is decoded by observers, such as human retina and CCD sensor, as different images based on their spectral sensitivity. The experimental results show the effectiveness of the new image representation method.
