3D Ready HDTVs Have NOW HIT THE MARKET!!!!

3D History

In June 1838, Sir Charles Wheatstone addressed the Royal Scottish Society of Arts on the phenomena of binocular vision. Wheatstone showed that horizontal disparity (objects at different distances) was an effective depth cue by creating the illusion of depth from flat pictures that differed only in horizontal disparity. To display his pictures separately to the two eyes, Wheatstone invented the stereoscope. His mirror stereoscopic viewer required that both pictures in the pair be reversed laterally. In describing the equipment he said: “I…propose that it be called a Stereoscope to indicate its property of representing solid figures. Wheatstone’s actual stereoscope is preserved at the Science Museum in London.

Some methods, such as time sequential left/right eye addressing (active glasses), will negatively affect viewer’s vision systems and cause discomfort to various degrees. Because the left and right eye shutters in the glasses alternately open and close to assure each eye sees only the appropriate image, the brain must work overtime to compile these sequential images into one image that ultimately shows the 3D effect. This extra demand on the brain leads to nausea and headaches. Nevertheless, for critical data acquisition and tasks that cannot be carried out otherwise, such as laparoscopic surgery or complex molecular modeling, doctors, engineers and scientist will resort to time sequential 3D viewing. In the entertainment industry, 3D movies were released as early as 1915. Although during the past century Stereo Viewing Equipment and content was developed for entertainment, these efforts all fell short of expectations in image quality and viewing comfort.

However, with the advances in camera technology and computer graphics content creation, the movie industry is focusing on 3D once more. With IMAX being probably the leader with its 3D cameras that incorporate two identical lenses which are precisely spaced to match the distance between human eyes. To enable the 3D effect, polarized glasses worn by the audience are precisely matched with the polarizing filters of the projector’s twin lenses. While the projector lenses superimpose separate left and right eye views on the screen, the polarizer glasses make sure that each eye sees the appropriate image, allowing the brain to create a single 3D image.

Presently, because of rapidly advancing technology and market conditions, 3D in the entertainment market is receiving renewed attention. Compelling 3D content for home entertainment is prevalent only in the electronic gaming market. Electronic games are the largest and only cohesive addressable market segment. With its annual hardware and content revenues of over £50 billion, and hundreds of games designed in 3D, this market is ready for 3D monitors. Playing games in 3D is a new dimension that makes players feel part of the game. The rapid growth of the public’s interest in 3D is underlined by James Cameron recent statement: 3D display will become a must for video and computer. With the promise of compelling content, 3D monitors are becoming consumer electronics products which pave the way for 3D to enter the home, not only for game playing, but also for TV entertainment.

Video Production

To produce 3D Video, it is necessary to use multiple cameras that are recording from separate perspectives. There are 3 options to achieve this: 1- a standard 2D camera image and a post-produced depth map; 2. Dual/side-by-side camera setup; 3. A series of 8 cameras aligned on a single mount in parallel.

3D Ready HDTVs Have NOW HIT THE MARKET!!!!

These exciting new products provide the ultimate entertainment experience. Images float in mid are and move into and out of the screen in full color, HD quality. Various developments in optical, graphics and software technologies have made this possible today. 3D HDTV is the new revolution in multi-media.

Some TVs are pre-built with forward compatibility for 3D Gaming and Movies!

Recent HDTVs have gained 3D capabilities to generate true-depth, 3Dimensional images by incorporating various optical technologies. Generally speaking, there are displays that require special glasses and displays that do not require special glasses. Currently, Tru3D is focused on glasses-based consumer 3D Ready HDTVs.
