3D Television Image
A 3D
Television can work in different ways, but the end result is the same. You must wear special glasses, that is for sure, they willseparate two different Left and Right images so that each image only enters your Left and Right eyes respectively.
If you film something using a stereoscopic camera (two cameras built in one) at about eye-width apart and then you play back that Left video camera into your Left eye and the Right video camera into your Right eye, you see a real 3D image that actually pops out of the screen and has depth.
3D Televisions can be used with special 3D glasses to correctly separate the Left and Right views out of a compatible 3D video source, if you didn't have it, it would just be a fuzzy 2D Television effects.
3D Blu-Ray players and 3D Televisions are expected to be available on the consumer market later this year along with some new Blu-Ray 3D movie releases. Some cable and satellite Television providers are already working on bringing 3D Television broadcasts to the home provided that you have a compatible Television set. Get excited!
At the begining I said a 3D
Television can work in different ways. This is because there are two popular 3D viewing technologies which are in competition right now. There is the polarized viewing method and the active shutterglass method (shutterglass looks like it will be more popular because it's cheaper to manufacture the Televisions using this method).
Polarized 3D takes advantage of the fact that light can be polarized and filtered at different angles. If you build a Television that can display two different images at once that are polarized at different angles, you can make cheap plastic glasses that can filter out one of the images so that each eye only sees the correct image.
Shutterglass 3D works by flashing the left view and the right frame in sequence extremely quickly (120 times a second). The battery
powered glasses are synchronized to the screen so they close the shutter for the eye when it's view is not showing and 'open' the shutter for the eye with the correct view showing. This is done so quickly you don't even notice. Shutterglasses are pretty expensive though ($100-200 a pair).
