3D TV (3DTV) is a television, which employs a technique for 3D presentation, such as the capture stereoscopic multi-view, the taking or 2D-plus-depth, and 3D display of the design of a display device Special television program in a realistic three-dimensional field. 3DTVs was introduced in the market for Panasonic, LG and Samsung.
In late 1890, the film pioneer William Friese-Greene Columbia filed a patent for a process of 3-D movie. When viewing stereoscopic images, it showed that the two are combined in the brain to produce depth perception in 3-D. On June 10, 1915, Edwin S. Porter and William E. Waddell presented tests to an audience at the Astor Theatre in New York. In red-green anaglyph, the audience were three test lists, which included rural scenes, test shots of Marie Doro, a segment of John Mason has a number of passages from Jim Penman (a documentary produced by Famous Players-Lasky this year, but not in 3-D), belly dancing, and a roll of film, Niagara Falls. However, according to Adolph Zukor in his autobiography of 1953, the audience is never wrong: my 50 years in the film industry has not been produced in this process after these tests.
There are several techniques to generate and display 3D images in motion. The basic requirement is to replace the images on the screen, which is filtered to separate the left and right eyes. Two strategies have been used to achieve this goal are the glasses of the viewer to filter to separate the two offset images of the eyes, or share pictures of the light source directions, in the eyes of the viewer (no glasses required). Common 3-D visualization technology protruding pairs of stereoscopic images of the viewer are:
Lenses: 3D anaglyph (red-cyan glasses passive), the polarization 3D (passive polarized glasses), Alternate-frame sequencing (slow shutter on), a head-mounted display (with a separate monitor positioned in front of each eye, and lenses are primarily used to relax the eye AF)
Without the second contact lens: Auto-stereoscopic 3D sometimes called Auto commercially. Simple view shows the project is only a stereo pair at a time. Multi-view displays or use head tracking to change the display based on the viewing angle, or multiple projects simultaneously independent views of a scene to multiple viewers (self multiscopic) these multiple viewpoints can be created on the fly using the 2D format further.
Various display technologies are described, such as display of volume holography, and Pulfrich effect, which has been used to Doctor Who Dimensions in Time in 1993, the third rock from the sun in 1997, and Discovery Channel Shark Week 2000 mm. Real-time 3D TV (YouTube video) is basically a form of auto stereoscopic display. 3D TV are those that can operate in 3D mode (in addition to ordinary 2D), in conjunction with a set-top box and LCD shutter glasses, which tells the television shows that the eye should see the image exposed to the moment to create a stereoscopic image. These TVs generally supports HDMI 1.4 and (if an LED-backlit LCD TV) a minimum rate (input and output) of 120 Hz refresh rate, the glass can be sold separately.
