摘要
An entire-visual-field projection device which projects image information relating to an entire-visual-field image onto a spherical screen to provide the entire-visual-field image to a viewer positioned inside the screen. The projection device is provided with the spherical screen, a pair of projectors which project the entire-visual-field image onto the screen and are arranged opposite each other with the center of the screen therebetween, and a double-convex mirror for projection which reflects luminous fluxes from the projectors toward the screen and is disposed in the vicinity of the center of the screen. A projection luminous flux from one of the projectors is emitted to one of the convex surfaces of the mirror, and that from the other projector to the other convex surface of the mirror.
