The findings of Edwin H. Land in his experiments on the color-vision process in man indicate that the human eye can distinguish practically all the colors of the spectrum in an image that has been constructed using only two discrete colors of light, whereas the conventional theories of color vision maintained that a minimum of three colors was necessary. A study was undertaken, therefore, to test the feasibility of displaying the Land-effect on a closed-circuit television system. Lands experimental arrangements were duplicated, using photographic film, to ensure a familiarity with the techniques and type of results to be expected. The method was then adapted to the television system, and it was found that the results so obtained were equal, if not superior, to those obtained with photographs. Although images produced by this two-color method lacked some of the fine distinguishability of hue and saturation available in a three-color system, it was concluded that the use of the Land-effect in electronic display devices would be advantageous in situations where a true rendition of the colors of a scene is not required but where a variety of colors is helpful in increasing clarity or in presenting information that could not be rendered in black and white. It should also be of interest in cases where the picture does not have to be of standard commerical broadcast quality. Author
