It seems that everyone is talking about 3D television these days. A few friends and relatives who called up for advice regarding what TV to buy even asked if they should wait till next year to get a 3D TV. Given the recent interest, we thought it would be appropriate to give a brief explanation of the mechanics behind stereoscopy – any technique that creates the illusion of depth of three-dimensionality in an image.
There is one basic preface needed in understanding 3D television: understanding how our eyes work. For the sake of this example, look at your computer mouse (or if you’re on a laptop, any other object nearby). In a nutshell, your left eye and your right eye are two separate lenses, registering two differently-angled images of the mouse, which are then sent to your brain. The brain then acts as the ‘image processor’, putting the two pictures together to come up with one three-dimensional picture in your mind. It’s basically the same principle by which the new FujiFilm FinePix 3D TV camera works.
