<p><P>PROBLEM TO BE SOLVED: To reproduce a natural and exact starlit sky while keeping the positional accuracy of stars similarly to before and preventing a dividing border line from being conspicuous even when the number of projection fixed stars is extremely increased in dividing/projecting in a planetarium, and to easily determine the direction to be adjusted by viewing and adjust it even when the positional accuracy exceeds a tolerance. <P>SOLUTION: In projecting the starlit sky of the whole sky on a dome screen by composition of divided/projected images from a plurality of projectors, the divided/projected images 1 are interconnected without overlapping and are projected, and the shapes of these divided/projected images are set to be non-projecting shapes. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
