Abstract

The perception of three dimensions (3D) depends upon many cues to the brain. Parallax, shading, focus differential movement and stereo or separate images all contribute to the Perception. To be effective three dimensional display systems require separate images for each eye. The vertical parallax and separate view are the primary aids in using the mind to perceive 3D. Different methods are used to project or produce different images to each eye. The primary methods use shutters and or polarization to produce images for each eye. Active glasses using LCD shutters are the typical example of this method. Other current methods use an LCD light rotator over the projector CRT or screen and passive glasses over the eyes to provide different left eye and right eye images. The illusion of reality can be created with high quality 3D images. When the clarity or resolution of the images approaches that of real life, then the 3D fusing becomes easier to maintain and the illusion of reality becomes more pronounced. We will discuss an enhancement system that sharpens the edges of video images and demonstrates the improved 3D fusing that is produced.
