What is 3DTV

3D is based on the way the human brain and eyes work. Because the pupils of a person’s eye are about 6.5 cm (about 2.5”) apart, each eye views a scene from a different angle and generates a unique image.


The brain merges the images to create a single picture. The slight difference between the image from the right eye and the image from the left eye allows the brain to judge the depth. Stereoscopic vision is attained.

When a person views media such as photographs and television in 2D, each eye gathers essentially the same information. In other words, because the image has no real depth, there is only one way of viewing it. If there is any 3D impression at all, it comes from visual clues in the image, such as perspective.
