3D Glasses Amanda Villarreal Jasmyn Santos
What are 3D glasses • 3-D imaging is a technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. • Many 3D displays use this method to convey images.
Sir Charles Wheatstone • It was first invented by Sir Charles Wheatstone in 1838. • Sir Charles Wheatstoneborn on February 6, 1802 and died on October 19, 1875), was an English scientist and inventor of many scientific breakthroughs of the Victorian era The first use of 3D glasses was in 1922 for the movie "Power of Love". • http://en.wikipedia.org/wiki/Charles_Wheatstone
How Do they work • Since your eyes are about two inches apart, they see the same picture from slightly different angles. Your brain then correlates these two images. This is called binocular.Example of a system: • The binocular vision system relies on the fact that our two eyes are spaced about 2 inches apart. So each eye sees the world from a slightly different perspective, and the binocular vision system in your brain uses the difference to calculate distance. Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different.
Using glasses at the movies • The reason why you wear 3-D glasses in a movie theater is to feed different images into your eyes. The screen actually displays two images, and the glasses cause one of the images to enter one eye and the other to enter the other eye. A common systems for doing thisis…
Red, Blue, Green system • Although the red/green or red/blue system is now mainly used for television 3-D effects, it is still used for 3-D movies. In this system, two images are displayed on the screen, one in red and the other in blue (or green). The filters on the glasses allow only one image to enter each eye, and your brain does the rest. http://www.3dglassesonline.com/learn/how-do-3d-glasses-work
