Shutter Glasses
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of 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 the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CrystalEyes Shutter Glasses
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." Career Puff, the Magic Dragon Lipton was 19 when he wrote the poem that wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaglyph 3D
Anaglyph 3D is the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into the perception of a three-dimensional scene or composition. Anaglyph images have seen a recent resurgence due to the presentation of images and video on the Web, Blu-ray Discs, CDs, and even in print. Low cost paper frames or plastic-framed glasses hold accurate color filters that typically, after 2002, make use of all 3 primary colors. The current norm is red and cyan, with red being used for the left channel. The cheaper filter material used in the monochromatic past dictated red and blue for convenience and ...

Frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute (2 hertz), the period, —the interval at which the beats repeat—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. Definitions and units For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term ''frequency'' is defined as the number of cycles or vibrations per unit of time.

M-3DI Standard
The M-3DI Standard, announced by Panasonic Corporation together with XpanD 3D in March 2011, aims to provide industry-wide compatibility and standardisation of LC (Active) Shutter Glasses hardware between manufacturers. This movement aims to bring about compatibility among manufacturers of 3D TV, computer, notebook, home projection, and cinema with standardised LC (Active) Shutter Glasses that will work across all 3D hardware seamlessly, with the hope of further increasing uptake of 3D products by consumers. The M-3DI Standard will also feature a comprehensive quality control and testing specification to apply during the production of 3D LC Shutter Glasses; This specification is yet to be finalised and published. Industry Support Various leading 3D technology providers for televisions, projectors and cinemas have agreed to participate in supporting the new standard. Current providers include: *Panasonic Corporation formerly between 1935 and 2008 and the first incarnati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panasonic Corporation
formerly between 1935 and 2008 and the first incarnation of between 2008 and 2022, is a major Japanese multinational conglomerate corporation, headquartered in Kadoma, Osaka. It was founded by Kōnosuke Matsushita in 1918 as a lightbulb socket manufacturer. In addition to consumer electronics, of which it was the world's largest maker in the late 20th century, Panasonic offers a wide range of products and services, including rechargeable batteries, automotive and avionic systems, industrial systems, as well as home renovation and construction. Panasonic has a primary listing on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX 100 indices. It has a secondary listing on the Nagoya Stock Exchange. Corporate name From 1935 to October 1, 2008, the company's corporate name was "Matsushita Electric Industrial Co." (MEI). On January 10, 2008, the company announced that it would change its name to "Panasonic Corporation", in effect on October 1, 2008, to ...

Pixel Response Time
In technology, response time is the time a system or functional unit takes to react to a given input. Computing Response time is the total amount of time it takes to respond to a request for service. That service can be anything from a memory fetch, to a disk IO, to a complex database query, or loading a full web page. Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time. The wait time is how long the request had to wait in a queue before being serviced and it varies from zero, when no waiting is required, to a large multiple of the service time, as many requests are already in the queue and have to be serviced first. With basic queueing theory math you can calculate how the average wait time increases as the device providin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polarized 3D System
A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low-cost eyeglasses with a polarizing filter for each eye. The left and right filters have different polarizations, so each eye receives only the image with the matching polarization. This is used to produce a three-dimensional effect by projecting the same scene into both eyes, but depicted from slightly different perspectives with different polarizations. Multiple people can view the stereoscopic images at the same time. Polarized 3D systems, and stereoscopy systems in general, commonly exhibit the Vergence-Accommodation Conflict. Types of polarised glasses Linearly polarised glasses To present a stereoscopic motion picture, two ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
