A system and method are disclosed for exhibiting wide-screen motion pictures, including in multiplex-style theaters, with an immersive, 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 14 to 22 foot-lamberts of light to the screen. The invention can support any theatrical aspect ratio for presentation, including the widest in use, 2.76:1. To eliminate image distortion, the invention uses warping 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 that will be accommodated 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.

A filter, having a first filter material and second filter material, the first and second filter materials having different light attenuation properties and being in mutual contact along an interface surface, a cross-section of which has a curved line. Additionally, a method for preparing a filter, by: combining a first surface and an element to form a moulding cavity, delimited by the surface and by a moulding surface of the element; inserting a first material in liquid state; allowing the first material to solidify; removing the element to form a second moulding cavity, delimited by a second part of the surface and by the solidified first material; and inserting a second material in the second moulding cavity.

A vehicle projection system that includes a projector positioned adjacent a first portion of a ceiling of the vehicle, the projector being configured to project a first image on the first portion of the ceiling. The image may be a moving image or may be various natural sky scenes such as a starry sky. The projector may be a pico-projector or a micro-projector. The vehicle may be an aircraft with the projector positioned on an overhead portion of the cabin. The projector may be positioned between two overhead bins. A second projector positioned on an overhead portion of the cabin may be configured to project a second image on a second portion of the ceiling. The projectors may be positioned on curtain headers within the aircraft. The system may include a control panel that controls the operation of the projectors in conjunction with an onboard sound system, if any.

A first illumination light source emits a first illumination light ray which is a first polarized light. Either one of an s-polarized light and a p-polarized light, which are linearly polarized light, is the first polarized light and the other is a second polarized light. A second illumination light source emits a second illumination light ray. A dichroic mirror includes a specific polarization reflection area and a transmission area. The specific polarization reflection area reflects the first polarized light and transmits the second polarized light and the second illumination light ray. The transmission area transmits the first and second illumination light rays. A phase difference plate converts linearly polarized light into circularly polarized light. A polarization conversion element transmits either the first or second polarized light, shifts an optical axis of the other, and aligns the first and second illumination light rays to the first or second polarized light.

A control device configured to communicate with a first projector which projects a first image in a first projection area, and a second projector which projects a second image in a second projection area having a first overlap area overlapping the first projection area to make the first projector and the second projector perform an edge blending process includes a reception section for receiving input of designation information including a direction in which an overlap width, a generation section for generating first overlap information including information representing first side in the first overlap area and information representing the overlap width of the first overlap area, and second overlap information including information representing second side in the first overlap area and the information, and a transmission section for transmitting the first overlap information to the first projector, and the second overlap information to the second projector.

Systems and methods to reduce the appearance of a seam in an image reflected onto a mirror array from a screen is provided. The systems and methods may include a light source to emit light into a seam between a pair of mirrors of the mirror array; a camera for taking a picture of the image displayed on the screen and yielding image data from the picture; and a control system in communication with the light source and the camera. The control system may be operable to cause the light source to emit light of a first color into a first portion of the seam and to emit light of a second color into a second portion of the seam based on the image data, thereby providing colored light in the seam to substantially match colors in the image reflected onto pair of mirrors adjacent to the seam.

There is provided a projection system including a plurality of projectors that perform edge blending, each of the plurality of projectors including: an image display element; a light blocking plate that reduces an amount of light in an edge overlapping portion of a light bundle; and an aperture diaphragm that changes an amount of light traveling-toward an object to be projected, wherein when a circle formed by an outermost perimeter of a light passing region obtained when the aperture diaphragm is completely opened is defined as a reference circle, the aperture diaphragm partially covers the inside of the reference circle such that an outline of the reference circle is divided into three or more sections in a state where the aperture diaphragm is narrowed to make an area of the light passing region inside the reference circle half the reference circle.
