Abstract: 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.

Abstract: A video signal processor intended to be connected between a computer video output and a monitor that transforms non-interlaced video output into interlaced video output intended to be used for presentation of stereoscopic video 2D images, giving illusion of 3D presentations. The invention also comprises LCD glasses connected through infra-red light beams to the video signal processor for alternatively opening one of the glasses' eye in accordance with the current image being shown onto the video monitor. The present invention also provides greater resolution by replacing the blank lines from an interlaced image by the previous adjacent image line.
