BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a two (2-D) to three dimensional (3-D) video conversion and image enhancement system, and more particularly, to a system that converts a television, computer or other two-dimensional (2-D) screen system into a 3-D image and that removably attaches to an existing television, computer screen or other video monitor to convert a 2-D video projection to a 3-D video image.
2. Description of the Background Art
Three dimensional (3-D) movies, games and videos have become increasingly popular in recent years. This is in part due to 3-D attractions at amusement parks and the evolution of 3-D televisions. Typically, 3-D glasses are required to watch a 3-D VIDEO image. The 3-D technology has advanced to the point where television manufacturing companies are now boasting televisions with 3-D imaging. However, the availability of 3-D televisions for the average person is limited by costs. In addition, most people already own televisions. Moreover, 3-D glasses are known to be bulky and uncomfortable. Accordingly, even though people would like to be able to enjoy 3-D viewing they do not want to spend the money it takes to purchase a new 3-D television or want to wear 3-D glasses. Another feature television viewers and computer users would like to have is the ability to magnify the projected image. If there was a 3-D accessory that converted a two-dimensional (2-D) projection into 3-D it would allow people to watch 3-D on their current televisions or computers without 3-D glasses and would be well received. If there existed an accessory that magnified a television or computer projection it would allow people to enhance the projected image for easier and more enjoyable viewing. In fact, it would be desirable to have an accessory that provided 3-D viewing without 3-D glasses as well as magnification of the screen image.
There are a variety of devices for producing three dimensional visual displays, however, none of these devices address or effectively resolve the foregoing needs in the background art. For instance, U.S. Pat. No. 4,000,367, issued to Field, discloses an apparatus for producing depth effect in two, dimensional pictures.
