ABSTRACT:
A multi-direction image viewing system includes a triangular or rectangular image case, and plural projectors symmetrically installed to the inner sides of the image case in three or four directions. Projecting light paths cross each other so that the size of the image case is reduced to 1/6.7 to ⅓ of the size of the conventional image case. By reducing the weight of the image case through size reduction, the multi-direction image viewing system can serve as a mobile multi-direction image viewing system coupled with a trailer and transported by a small sized vehicle such as a motorcycle, as a wide viewing angle multi-direction image system attached to a wall and coupled with the safety fence of the bus terminal or the subway station, and as an image viewing system mounted to a ceiling or wall.
