A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, virtual reality picture-dominance effect not previously obtainable in such theaters. The invention uses a zero-gain or nominal-gain curved screen to accommodate a wide-screen presentation, and a digital projector capable of delivering fourteen foot-lamberts or more of light to the screen. It can support any theatrical aspect ratio for presentation, including 2.76:1. To eliminate image distortion, the invention uses mapping software to correct the image for the geometry of the auditorium and the shape of the screen. This correction is established for every aspect ratio displayed in the auditorium in which the invention is installed, and aspect ratios can be changed to display content with different aspect ratios during a program. The images delivered to viewers through the invention deliver the full benefit of the native aspect ratio in which they are displayed.

In one aspect, a light assembly is configured to be installed in a movie theater projector and includes an adaptor configured to mechanically couple to a bulb mount of the projector, a primary LED Emitter mounting plate and LEDs attached to the primary LED Emitter mounting plate. The light assembly also includes a heat sink configured to dissipate heat from the primary LED Emitter mounting plate, a cooling fan configured to generate airflow across the heat sink, a lens mounting plate and a lens configured to collimate light emitted from the LEDs, where the lens is disposed over the lens mounting plate. The light assembly also includes an attachment assembly configured to attach the lens mounting plate to the primary LED Emitter mounting plate. The adaptor may be manipulated to adjust a distance between the bulb mount of the movie theater projector and the primary LED Emitter mounting plate.

In an imaging section (imaging device), optical filters constituting an optical filter device are inserted and extracted, and an aperture varies an f-number in accordance with the insertion and the extraction of the optical filters. Thus, during the writing operation to the surface of the projection screen, namely during the interactive projector operation, entering of the light in the wavelength band other than that of the detected light DL is suppressed while capturing the detected light DL with the necessary light intensity, and during an alignment (a calibration), the axial chromatic aberration caused by the difference in wavelength band between the pattern image light GL as the image light and the detected light DL is suppressed to achieve an improvement in accuracy.

The present invention provides a performance system with a multi-projection environment including a stage installed for a performance and a plurality of projection surfaces arranged around the stage and arranged so as not to be parallel to each other, in which synchronized images are projected on the plurality of projection surfaces.

A projector has a body, a rotating device, a projection device, and a supporting device. The body has a lower housing, an upper housing, and an operation chamber. The rotating device is mounted in the operation chamber, is located in the upper housing, and has a driving device, a rotating axle, a power supply circuit board, and a film base. The projection device is mounted in the operation chamber of the body and has a light unit, a Fresnel lens, a film holder, and a lens assembly. The supporting device is mounted on a bottom of the lower housing.

A method and system for carrying out the following steps: In a first step of a method a first image or picture of a display system is captured when the system is operating nominally. In a second step, a second image or picture of the display system is taken. In a third step, the first and second images or pictures are compared and differences between first and second images pictures are evaluated to detect problems or failures of the display system.

A 3D laser projection systems and methods are disclosed herein. A laser projection system includes a left projector head and a right projector head, wherein a first video projected onto a movie screen by the left projector head has a first polarization and a second video projected onto the movie screen by the right projector head has a second polarization different from the first polarization. The laser projection system can include a laser light generator located a first defined distance away from the left projector head and a second defined distance from the right projector head and coupled to the left projector head and the right projector head with fiber optic cables that transmit light from the laser light generator to the left projector head and the right projector head. The laser light generator includes a laser diode configured to output light and to transmit it to the fiber optic cables.

The present invention relates to a curved ceiling structure, the ceiling structure characterized by having a curved shell shape over the seats of a theater while exposing the screen. Therefore, according to the present invention, structural continuity with the screen curved in horizontal and vertical axes can be ensured, and by ensuring design integrity with the screen curved in horizontal and vertical axes, a sense of immersion can be imparted to an audience and an enhanced life-like sensation can be delivered thereto.
