Abstract

1,095,030. Colour television cameras. MARCONI CO. Ltd. Sept. 7, 1966 [Dec. 10, 1965], No. 52653/65. Heading H4F. The Specification describes a colour television camera comprising viewing lens 1, Fig. 2, three-colour pick-up tubes, blue, TB, red, TR and green, TG, having respective colour responses given by the curves B, R and G, Fig. 1, and a luminance pick-up tube TL having the colour response given by curve L. The invention lies in that the correct spectral range according to curve L is directed to tube TL by means of a dichroic mirror 3 and trimming filter FL. 30% of the light of the viewed means is thus by-passed to the luminance tube and the remaining 70% is fed to the three colour tubes, the respective spectral ranges being extracted from the light according to the curves B, R and G by means of dichroic mirrors MB and MR together with training filters FB, FR and FG.
