The keystone effect is the apparent distortion of an image caused by projecting it onto an angled surface. It is the distortion of the image dimensions, such as making a square look like a trapezoid, the shape of an architectural keystone, hence the name of the feature. In the typical case of a projector sitting on a table, and looking upwards ...
SXRD (Silicon X-tal Reflective Display) is Sony's proprietary variant of liquid crystal on silicon, a technology used mainly in projection televisions and video projectors. In the front and rear-projection television market, it competes directly with JVC's D-ILA and Texas Instruments' DLP.
Transparency (projection) A transparency, also known variously as a viewfoil or foil (from the French word "feuille" or sheet), or viewgraph, is a thin sheet of transparent flexible material, typically polyester (historically cellulose acetate ), onto which figures can be drawn. These are then placed on an overhead projector for display to an ...
It aimed to increase acceptance of 3D products by consumers by extending the agreement to various manufacturers of 3D TV, computers, notebooks, home projectors, and cinema hardware. As of April 2011, the agreement was joined by Hitachi, Changhong, Funai, Hisense, Mitsubishi Electric, Epson, ViewSonic, and SIM2 Multimedia S.p.A.
A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp ), Xenon arc lamp, metal halide lamp, LED or solid state blue, RB, RGB or remote fiber-optic RGB lasers ...
Digital Light Processing. Logo. The Christie Mirage 5000, a 2001 DLP projector. Digital Light Processing ( DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments.
Many motion blur factors have existed for a long time in film and video (e.g. slow camera shutter speed). The emergence of digital video, and HDTV display technologies, introduced many additional factors that now contribute to motion blur. The following factors are generally the primary or secondary causes of perceived motion blur in video.
LCD projector. An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector. To display images, LCD ( liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series ...
