RealD Cinema
RealD 3D is a digital stereoscopic projection technology made and sold by RealD. It is currently the most widely used technology for watching 3D films in theaters. Worldwide, RealD 3D is installed in more than 26,500 auditoriums by approximately 1,200 exhibitors in 72 countries as of June 2015. Technology RealD 3D cinema technology is a polarized 3D system that uses circularly polarized light to produce stereoscopic image projection. The advantage of circular polarization over linear polarization is that viewers are able to tilt their head and look about the theater naturally without seeing double or darkened images. However, as with other systems, any significant head tilt will result in incorrect parallax and prevent the brain from correctly fusing the stereoscopic images. The high-resolution, digital cinema grade video projector alternately projects right-eye frames and left-eye frames, switching between them 144 times per second. The projector is either a Texas Instruments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZScreen
ZScreen is a push-pull electro-optical liquid crystal modulator that is placed immediately in front of the projector lens or computer screen to alternately polarize the light from each video frame. It circularly polarizes the frames clockwise for the right eye and counterclockwise for the left eye. The RealD 3D system now showing in theaters is using the ZScreen that was invented by Lenny Lipton.

Lenny Lipton
Leonard Lipton (May 18, 1940 – October 5, 2022) was an American author, filmmaker, lyricist, and inventor. At age 19, Lipton wrote the poem that became the basis for the lyrics to the song "Puff, the Magic Dragon". He wrote books on independent filmmaking and was a pioneer in the field of projected three-dimensional imagery. Leonard Lipton developed 3D cinema technology that is used in RealD 3D cinemas. His technology is used to show 3D films on more than 30,000 theater screens worldwide. In 2021, he published ''The Cinema in Flux'', an 800-page illustrated book on the history of cinema technology. Early life Lipton was born in Brooklyn, New York. He majored in physics at Cornell University after starting out in electrical engineering. A self-described "mediocre student", he only excelled once he found a field he loved. Lipton urged schools to be more "accepting of eccentric people with a different point of view because we are the people who make the difference." Career ...

MasterImage 3D
MasterImage 3D is a company that develops stereoscopic 3D systems for theaters, and Autostereoscopy, auto-stereoscopic 3D displays for mobile devices. 3D Cinema Technology The MasterImage 3D MI-CLARITY3D system for cinemas is a polarized 3D system that is based on the projector presenting a spinning polarized filter, which contains alternating segments of circularly polarized material. Mounted in front of the projector lens, this filter is synchronized to the projected images, giving each frame a polarization perpendicular to the previous one, which can be viewed with polarized 3D glasses. The filter wheel can be lowered out of the lens' path for non-3D material. It has been noted that an earlier version of the spinning polarized filter malfunctioned, but the problem has been addressed with an updated replacement filter which was supplied to all theaters using the system.

XpanD 3D
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique for displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image. Modern active shutter 3D systems generally use liquid crystal shutter glasses (also called "LC shutter glasses" or "active shutter glasses"). Each eye's glass contains a liquid crystal layer which has the property of becoming opaque when voltage is applied, being otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately block one eye, and then the other, in synchronization with the refresh rate of the screen. The timing synchronization to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolby 3D
Dolby 3D (formerly known as Dolby 3D Digital Cinema) is a marketing name for a system from Dolby Laboratories, Inc. to show three-dimensional motion pictures in a digital cinema. Technology Dolby 3D uses a Dolby Digital Cinema projector that can show both 2D and 3D films. For 3D presentations, additional filters are used in the projector, one filter each for the left eye and right eye. Each filter allows different frequencies of red, green, and blue light to pass through each of them. The filters are able to each produce a common color gamut but transmit light at different wavelengths. Glasses with complementary dichroic filters in the lenses are worn, which filter out either one or the other set of three light wavelengths. In this way, one projector can display the left and right stereoscopic images in an alternating cadence that is not visible to the guest. In alternate forms one filter is placed in each of two projectors, both pointed at the same screen, one displaying the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panavision 3D
Panavision Inc. is an American motion picture equipment company founded in 1954 specializing in cameras and lenses, based in Woodland Hills, California.

IMAX 3D
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio (approximately either 1.43:1 or 1.90:1) and steep stadium seating, with the 1.43:1 ratio format being available only in few selected locations. Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw were the co-founders of what would be named the IMAX Corporation (founded in September 1967 as Multiscreen Corporation, Ltd.), and they developed the first IMAX cinema projection standards in the late 1960s and early 1970s in Canada. IMAX GT is the premium large format. The digital format uses dual laser projectors, which can show 1.43 digital content when combined with a 1.43 screen. The film format uses very large screens of and, unlike most conventional film projectors, the film runs horizontally so that the image width can be greater than the width of the film stock. It is called the 15/70 forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital 3D
Digital 3D is a non-specific 3D standard in which films, television shows, and video games are presented and shot in digital 3D technology or later processed in digital post-production to add a 3D effect. One of the first studios to use digital 3D was Walt Disney Pictures. In promoting their first CGI animated film '' Chicken Little'', they trademarked the phrase Disney Digital 3-D and teamed up with RealD in order to present the film in 3D in the United States. A total of over 62 theaters in the US were retrofitted to use the RealD system. The 2008 animated feature '' Bolt'' was the first movie which was animated and rendered for digital 3D, whereas ''Chicken Little'' had been converted after it was finished.Official Disney Production Notes Disney.go.com.

Silver Screen
A silver screen, also known as a silver lenticular screen, is a type of projection screen that was popular in the early years of the motion picture industry and passed into popular usage as a metonym for the cinema industry. The term silver screen comes from the actual silver (or similarly reflective aluminium) content embedded in the material that made up the screen's highly reflective surface. History There are descriptions of a silver screen being used in the presentation of films as early as 1897. Film exhibitor Arthur Cheetham used one for some of his later cinematograph Living Pictures presentations, "now shown on a new silver screen which brings the pictures out almost as well as electric light." The novelty of this screen was emphasised by Cheetham, and he later named his the Silvograph. Reports mentioning silver screens don't appear in US papers until over a decade later. In 1909, the Lyric theatre in Smith St., New Jersey was "equipped with a new patent silver-coate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
