Abstract: A color television camera utilizing a vidicon tube that has a filter in the form of alternate stripes for the primary colors red, green and blue, a pair of electrodes for each set of three stripes and a photoconductive layer, an alternating voltage is applied to the electrodes to provide a predetermined pattern on the surface of the photoconductive layer in the form of an index signal which is overlapped on the photoconductive layer with the image to be reproduced. The composite signal on the photoconductive layer of an index signal and a color video signal is fed through the same terminals that applied the reference alternating voltage to the electrodes to a circuit which separates the color video signal from the index signal. The index signal is then applied to three demodulators to obtain the color video signals.
