MULTI-DISPLAY DEVICE, MULTI-DISPLAY SYSTEM AND ADJUSTMENT METHOD FOR MULTI-DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multi-display device or the like for observing an image constituted of plural partial images at almost uniform luminance even in a superimposing area. SOLUTION: This multi-display device is provided with plural projectors and is composed so as to constitute one image as the whole by arraying the partial images projected to a screen by the projectors while superimposing them on the partial images adjacent at the side edge in the superimposing area. In a light shielding plate for light-shielding a part of a luminous flux projected to the superimposing area so as to almost match the luminance of the superimposing area with the luminance of the partial image excluding the superimposing area, a light shielding part 15d for light-shielding a right side opposing the light-shielding part 15a for light-shielding the left side of a projection range 14 regarding the partial image can be displaced in a horizontal direction. Similarly, the light-shielding part 15c for light-shielding an upper side opposing the light-shielding part 15b for light-shielding a lower side can be displaced in a vertical direction.
