Abstract

A chromostereoscopic display consists of a single flat image in which the depth information has been encoded into color. The image is viewed through a pair of chromostereoscopic spectacles, each lens of which consists of one or more superchromatic prisms. The superchromatic prisms are designed to maximize the chromatic dispersion so that different colored objects are given different amounts of horizontal parallax while minimizing the amount of angular deviation of the line of sight so that colors with median wavelengths appear at the plane of the screen. Our purpose in this work was to investigate the possibility of CRT-based chromostereoscopic display. We were particularly interested in how many depth levels we could distinguish and the effect of RGB color combinations. Four types of experiments were conducted: 1) depth effect for nonoverlapping objects of different colors in an image; 2) depth effect for overlapping objects of different colors; 3) the depth effect produced by gradually modifying the shading of a single object from red to blue; and 4) relative depth position of the base phosphor colors and color combinations.
