3D-television:soon in every home

   , held in Las Vegas CES 2009 exhibition demonstrated that today in the world market is already there, or are preparing to conquer it, the various systems for 3D-image. In other words, the hardware base is fully prepared to add to the usual image today, the third dimension, and now the industry is three-dimensional movies/games/television broadcasts requires the appearance of content interesting to the end consumer. However, we propose to look at the situation in the 3D-video.
To begin with, the divide existing today stereodisplei two main types, based on the principle of formation of 3D-image. But first, we note that all the devices of this type are based on the properties of human vision - the formation of different images for the left and right eyes of the observer and allows you to create the effect of three-dimensional image. The first type stereodispleev include a device capable of forming an image in polarized light, and for each of the user`s eye a picture of the different angle of polarization (a difference of 90 degrees). The use of special polarizing filters that transmit light of one polarization and delay the other, and makes possible the sharing of images in two. The main advantage of technology is an opportunity to observe 3D-image, regardless of the location of the observer, but without special glasses picture completely loses its depth.
The second method is the separation of images for each eye of the user - the formation of two different frames are not at the same time, and consistently. In this case, requires an active glasses, periodically blocking the image to the left and right eye. However, this method makes specific requirements for the display - the frequency of the frame should be sufficiently high, and NVIDIA GeForce 3D Vision, announced the last of stereo systems, requires the use of displays with a frequency shift, no less than 120 Hz. The significant drawbacks of this approach is the need to accommodate the autonomous power supply and periodic recharging batteries headunits.
And it is the first way is still the most promising, in fact makes it relatively simple and low cost to build three-dimensional image. As we have noted, the use of simple polarizing filters do not require equipment stereoochkov power supplies, additional integrated circuits. The most the main obstacle before the advent of 3D-video on the world market - the need for the manufacture of television systems and display resolution, twice the desired picture. In other words, to implement the three-dimensional viewing of HD-movies (1080p) TV systems need to use resolution 2160p. However, over time, and the device will be equally familiar to the user, what are today`s HD-system.
As for the digital content for the three-dimensional displays, and there is significant progress - the leading film studios annually produce several paintings that are compatible with the 3D-displays. It is worth noting studio Pixar, which is already scheduled to release more than a dozen of 3D-animated films, and Disney promised that soon all the pictures produced by Pixar would show support for the 3D-screens. If you look at the market for computer games, the situation looks very promising - anonsirovannaya most recently 3D-System NVIDIA GeForce 3D Vision is compatible with a lot of projects have already produced, and most new games coming to master the third dimension.
