Abstract
By installing a diffuser between a group of projectors and lenses to spread light rays from the projector group, it is possible to provide pixels with such sizes as to give perception that pixels are adjacent to each other. As a result, smooth representation of images and video display with a high stereoscopic effect are made possible.
