Abstract
Abstract Television system selectively adaptable to three-dimensional viewing, the system comprising a television set having projector guns disposed thereon and adapted to project color images onto a screen, means for selectively positioning images projected by the projector guns, polarized filters for polarizing light projected from the projector guns, and a pair of eyeglasses including first and second polaroid sheets, each of the polarized filters being movable between a first position in which the filter is disposed between a projection gun and the screen and a second position in which the filter is disposed in an out of the way location.
