METHOD AND APPARATUS FOR ELIMINATING STEREOSCOPIC CROSS IMAGES

The preferred embodiment of the present invention compensates for the phosphorous glow of cathode ray tube displays which is retained from one image to the next and eliminates the ghosting effect seen when viewing 3-D images using shutter, polarized or colored stereoscopic glasses. It can additionally be used to compensate for light leaking through LCD shutter glasses. The source images for each eye are not displayed directly once modulated. The source images are modified using positive and negative ratio combinations of both eye images to be displayed to each eye. The displayed image for one eye is a percentage of the source image for that eye, minus a percentage of the source image for the other eye, plus a percentage of white. The ratio can be preset or modified in real-time by the viewer.
