Stereoscopy is the illusion of creating depth in two-dimensional (2D) images. The technique of stereoscopy is based on binocular vision, i.e., viewing two images at the same time, which gives a perception of depth. Human perception of three dimensions is based on a number of cues such as binocular parallax, motion parallax, accommodation, and convergence.
The advancements in display technology have taken this to a new dimension. Display technology is now moving from 2D viewing to 3D viewing. Adding another dimension to display devices increases the entertainment value to viewers, since images seem more realistic and life-like and appear to “pop out” from the TV screen. The entertainment and film industries continue to explore new and exciting ways of filmmaking and producing animations in 3D. The audiences too are showing more interest in films and animations that incorporate the latest viewing experiences.

Hence they are more likely to enjoy films that offer an immersive feeling where the audience feels like they are part of the scenes.
The popularity of 3D technology is found in entire world but this technology is not limited to entertainment only; instead it is moving into different fields, whether that is medical science, sports, or even lectures of primary students. Now content can be found in 3D stereoscopy. The growth of 3D technology assures us that in future, viewing devices will have additional feature of 3D in them. It can be assumed that large screen TVs, computer screens, smart phones, and tablet PCs all will be converted to 3D soon. Every new cinema shows 3D movies and almost every month there is a new 3D movie in the market that people are eager to watch.
By the end of 2009, Sony announced that it will be bringing 3D viewing into home viewing environment and experts claimed that “we will watch all our media in 3D within a decade.” Sony’s chairman Howard Stringer said that 3D will be the next $10 billion business.1 Other companies have also joined the 3D bandwagon, with the president of Samsung Electronics’ visual display division, Mr. Yoon Boo-Keun, announcing “Samsung aims to sell 2 million 3D LED TVs in 2010”.2 At present, there are a number of 3D TV choices available in the market, and most of them use either active or passive glasses.
