Abstract: A 3D image cinema system having at least one projection room for viewing 3D images or 2D images is divided into forward and rearward viewing directions for the projection of an image on a front screen and a rear screen which are provided in a front end and a rear end of the projection room, respectively. Further, a front direction chair and a rear direction chair having a different viewing direction are provided on a front step and a rear step between the projection room and the front and rear screens where the theater can be easily installed in a general building and the 3D and 2D image has as much as 1.5-2 times wider viewing as a prior image.

Abstract: Disclosed herein are exemplary embodiments of a projector having multiple projection paths and related methodology.

Abstract: A fiber-optic light system is disclosed for providing highly concentrated, cool light to projectors and reproducer sound heads, such as the type found in the projection room of a movie theater. The light beams onto a film to project the film's images onto a screen and release its soundtrack. In the preferred embodiment, a system is disclosed for providing fiber-optic light to a plurality of projector-and-reproducer sound sets from a single light source. A plurality of fiber-optic cables are connected to a standard xenon lamphouse, wherein each of the cables has a bifurcated "free" end with two trunks. One trunk removably connects to the projector by a coupling block that easily fits onto a mount attached to the projector's casing, while the other trunk connects to the reproducer sound head by a similar block and mount.

Abstract: A Super-8 mm. movie film with two amplitude modulated optical sound tracks, one in each margin of the film. A method for optically recording and reproducing audio information with high fidelity on a very narrow sound track. A scanning apparatus has lens and masks which accurately define and direct a light beam on the film sound track for high fidelity reproduction.
