摘要： In a system according to the invention, fine image data 2 created and output by a personal computer 1 is input to an image processing/dividing section 4. The image processing/dividing section 4 determines, on the basis of parameters stored in a projector arrangement storage 5, which portion of the fine image data 2 is output to which projector, thereby performing a predetermined processing. Digital signals from the image processing/dividing section 4 are input to a plurality of D/A converters 6, respectively, where the signals are converted to analog signals. Images in the form of the analog signals are projected onto a screen 8 from projectors 7a-7d. Thus, the image projected on the screen 8 is constituted of accurately positioned images, and hence is a very fine image.

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.
