Abstract: The colorimetric performance of a television camera is controlled by the color separation characteristics of the optics and the spectral response of the pickup tubes, neither of which is perfect. Based on an electronic method of varying the overall spectral response of a color TV camera chain, equipment has been designed to produce an improvement in color; however, due to control interaction the elements of these matrixes should be determined mathematically and trimmed only under laboratory conditions. These units are not suited to reducing camera matching errors. This system enables the use of a simple setup procedure requiring only a color test chart and a vectorscope. It is possible for an operator to adjust the colorimetry of a TV camera under typical studio operating conditions and to assure camera-to-camera matching. Noise introduction in the black-and-white portions of a televised scene is eliminated since no correction signals are generated in the absence of color.
