Today 3D televisions are spicing up the television market. These display devices are designed based on 3D technology which is basically presents picture in stereoscopic forms. Stereoscopic cameras will have two lenses at about eye-width. Here a single picture (taken by using Stereoscopic camera or virtually created) is projected differently to both the eyes. For right eye the projection will be from right side lens of the camera and so for the left eye as well. Therefore, when the picture is from 3D TV screen flipped quickly between two eyes they project an image on brain, which gives a 3D impact.
To give 3D images a greater impact, there are some common technologies that are used. The core function is to project the image differently to both the eyes. One way of doing this is through glasses that are worn while watching. Another technology is to split the image directionally through light source and this is how 3D televisions work, where the same impact is created without the glasses.
Some of the technologies that are used for 3D display this are;
1: Crossed –Hatched Technology: In this technology, to one eye the image is presented into vertical format, and to another eye the same image is presented in a horizontal format. When these two images are combined together they generate a 3D impact. This is the main technology that is used in Cinemas.
2: Side by Side Technology: In this technology there are two different images created for both eyes respectively and to give them a 3D impact there is a pair of glasses that help in synchronization of these two images, which finally results into a 3D effect.
3: Top and Bottom Technology: This technology presents the same image to both the eyes from different angles. To one eye the image is presented from top angle and to other eye the same image is projected from bottom. So when they are synchronized well, they give birth to 3D image.
4: Frame Packing Technology: This technology is highly used in creating 3D impact in blue ray discs. This is the ruling technology in electronic and chip industry for creating 3D impacts.
Shutter Glasses are vital signs for creating a 3D effect. The shutter glasses are basically an expensive pair of glasses, which has a layer liquid crystal on lenses that turns dark when voltage is applied. Infrared help in signal transmission to sync the Shutter Glasses with the 3D TV set and it’s electronic circuits controls them in creating the 3D impact, when they are worn while watching TV.
The content for 3D are basically pulled out from three major sources.
1: Blue Rays: The movies that are offered by major movies studios under Blue Ray titles are ripe with 3D content.
2: TV Broadcasting: The 3D contents are pulled out from air with the aid of the television broadcasting services providers.
3: 2D-3D Conversions: The 3D content is also obtained by converting all 2D images into 3D images.
Talking about getting 3D contents by converting all 2D images, means that the 2D images, with the help of a program or software are given an impact of 3D and this is what is very well applied in televisions. With the help of this all shows and movies of televisions get a new appeal.
Therefore, leave behind the old way of watching movies and shows and spice up your television watching with 3D effect.
