摘要:
The present invention provides a multi-display device that has a plurality of projectors and constructs one image as a whole. Partial images projected on a screen from the projectors overlap to have the edges thereof superposed on edges of adjoining partial images in shared fields on the screen. A sheet interceptor intercepts part of light to be projected on a shared field so that the luminance level in the shared field will agree with the luminance levels in the other fields except the shared fields. An interceptor portion of the sheet interceptor, which intercepts light from the right-hand side of a range on the screen within which a partial image is projected, can be displaced horizontally relative to an interceptor portion thereof that intercepts light from the left-hand side thereof. Likewise, an interceptor portion of the sheet interceptor that intercepts light from the upper side of the projected range can be displaced vertically relative to an interceptor portion thereof that intercepts light from the lower side thereof.
