PROBLEM TO BE SOLVED: To provide an entire-visual-field projection device capable of projecting an image on the nearly whole area of a spherical screen while applying a sufficient antiglare treatment to projection light irradiation, although the configuration is simplified, and to provide an entire-visual-field image system.SOLUTION: An entire-visual-field projection device 20 projects image information onto a spherical screen 23 to provide an entire-visual-field image to a viewer 30 positioned inside the screen. It is previously determined what position of each of light valves of projectors 21A and 21B a light flux projected to the face periphery of the viewer 30 passes through, and the position through which the light flux passes is made a black level region to reduce illuminance of the light ray directly entering the eyes of the viewer 30. Because each of the light valves has a conjugated position relation with the screen 23, antiglare effect is improved by setting the position of the face of the sitting viewer 30 to be as close to the screen 23 as possible. |
