Signal mixing enhances 3-D imaging procedure
By combining parallax information from two vertically displaced cameras into a single video signal, researchers recently successfully produced 3-D presentations of video images and computer-generated graphics that can be scaled accurately in all three dimensions and can be viewed directly without use of special glasses or monitors.
