ABSTRACT:
A color filter strip arrangement for a color television camera tube which produces luminance and chrominance signals, and in which the chrominance signals are separeted from each other by phase division. A biasing light source is provided for illuminating the color filter to provide a minimum light level against a black frame at the periphery of the filter in order to enable discrimination of chrominance components when the scene being televised is at an extremely low light level. In another embodiment the strip arrangement involves combinations of first and second colors, and has a strip of the first color, a strip of the second color and a black strip. These combinations of strips are, in turn, separated by transparent strips.
