Abstract
This invention relates to a system for photographing, presenting and viewing 3D images, in which a set of mutually extinguishing multichrome A and B filters in spectacles is utilized to cover a first eye with an 'A' green filter and a second eye with a 'B' magenta filter. The 'A' greenfilter transmits at 450 to 580 nm and peaks about 515 to 540 nm. The 'B' magenta filter absorbs from 475 nm to 575 nm. Standard color film may be utilized to photograph stereo image pairs of the object in which a first image is in green, and a second image is in red and/or blue. With this system, one eye transmits a first stereo image in green via retinal receptors to the brain and the other eye transmits a second stereo image in red and/or blue via other retinal receptors to another portion of the brain. Thus, the stereo images are separated according to their 3-dimensional displacements and color. The brain integrates the color and 3D information received by the two eyes to produce a full 3D color picture. The 3D color system of this invention is compatible with still and movie color photography, printing inks, and color 3D TV. For color 3D TV using a cathode ray tube color screen, the green dots display the first stereo image and the red and blue dots display the second stereo image. Another new set of 'C' and 'D' mutually extinguishing filters is described, which may be employed in lieu of the set of 'A' and 'B' filters.
