Abstract
A single tube color television camera employs a camera tube and two color strip filters located one behind the other in the optical image axis. The strip filters may either be installed in the camera tube or structurally separated therefrom and have different color filter effects whereby both filters have the color strips thereof angularly displaced with respect to the vertical image axis by the same angle, but in opposite directions. The television camera also comprises a decoding arrangement containing a comb filter for splitting the output signal of the camera tube to provide a luminous brightness signal and two color signals each having a spectrum containing frequencies which are shifted with respect to an integral multiple of the line frequency by a fraction of the line frequency, one color signal being shifted toward higher frequencies and the other toward lower frequencies.
