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] |
Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye ...

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 went on to write books on independent filmmaking and become a pioneer in the field of projected three-dimensional imagery. 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."

MasterImage 3D
MasterImage 3D is a company that develops stereoscopic 3D systems for theaters, and 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.

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panavision 3D
Panavision is an American motion picture equipment company founded in 1953 specializing in cameras and lenses, based in Woodland Hills, California. Formed by Robert Gottschalk as a small partnership to create anamorphic projection lenses during the widescreen boom in the 1950s, Panavision expanded its product lines to meet the demands of modern filmmakers. The company introduced its first products in 1954. Originally a provider of CinemaScope accessories, the company's line of anamorphic widescreen lenses soon became the industry leader. In 1972, Panavision helped revolutionize filmmaking with the lightweight Panaflex 35 mm movie camera.

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. 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, Limited), and they developed the first IMAX cinema projection standards in the late 1960s and early 1970s in Canada. IMAX GT is the large format as originally conceived. It 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 a 70/15 format. It is used exclusively in purpose-built theaters and dome theaters, and many installations limit themselves to a projection of high quality, short documentaries. The high costs involved in ... [...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. Invented by Akron, Ohio projectionist Harry Coulter Williams, the "Williams Perlite" was an all-purpose, tear-resistant, vinyl plastic indoor motion picture screen that was installed in all the major movie houses of the day, including the rapidly expanding theaters built by Warner Bros of nearby Youngstown, Ohio. Williams' unique silver-painted screens were adapted for CinemaScope, VistaVision, and later 3-D movies. They provided a brighter picture at all angles with top reflectivity at direct viewing and extra diffusion for side seats and balconies. Metallic screens increased in popul ...
