Abstract:
A system for producing and displaying pairs of first and second spectrally-multiplexed images of a three-dimensional object for use in 3-D stereoscopic viewing thereof substantially free of image flicker, said system comprising:(A) first pixel data set producing means for producing a first set of pixel data elements representative of a first perspective image of said object and each said pixel data element thereof including color codes representing first and second groups of spectral components contained in said first perspective image;(B) second pixel data set producing means for producing a second set of pixel data elements representative of a second perspective image of said object and each said pixel data element thereof including color codes representing first and second groups of spectral components contained in said second perspective image;(C) pixel data element processing means for(i) analyzing the color codes of pixel data elements in said first and second pixel data sets,(ii) determining which pixel data elements in said first and second pixel data sets have color code values of a prespecified magnitude for one of said first and second spectral component groups, and(iii) assigning a filler pixel to each said pixel data element in said first and second pixel data sets which has been determined to have at least one color code value of said prespecified magnitude, thereby producing modified first and second perspective images;(D) pixel data element multiplexing means for multiplexing the color codes of pixel data elements in said modified first and second perspective images so as to produce third and fourth sets of pixel data elements representative of first and second spectrally-multiplexed images, respectively; and(E) image display means for sequentially displaying said first and second spectrally-multiplexed images using said third and fourth sets of pixel data elements,whereby a human viewer viewing said displayed first and second spectrally-multiplexed images can stereoscopically perceive said three-dimensional object substantially free of image flicker.
