| Outline of Final Research Achievements |
Projected image on a screen is not always vivid enough when it is projected in a bright room where audiences want to read paper documents simultaneously. We have suggested a new projection system which can realize high contrast image projection in a bright room. This paper describes the construction and performance of a prototype of vivid image projection system using an e-Paper screen.
We have prototyped a novel projection system which consists of an alternating e-Paper screen, an alternating LED room lighting, and conventional projector in order to achieve a vivid image projection in a bright room. Measured results have shown that more vivid and clear image projection than that of in the conventional system is achieved by our new system. The improved vividness and contrast have also been confirmed by subjective evaluation results.
