Analysis of Color Errors in Color Television Cameras

In the configuration of color television cameras, at least three systems have been used. The first, and most familiar, makes use of three tubes whose spectral response corresponds to the red, green and blue components, respectively, of the scene. A second type substitutes a tube having a spectral response proportional to the luminosity curve, ȳ, for the green tube. Still a third makes use of four tubes which correspond to the three primaries as well as the luminosity curve. Due to the gamma correction, the latter two systems theoretically result in chromaticity and luminance errors in the reproduced picture. An analysis is made of the nature of these errors. Calculation is also made of the chromaticity shading which results from shading of the output of one of the three (or four) tubes. Experimental results are also described.
