Abstract

1,072,481. Colour television.ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 31, 1964 [Jan. 31, 1963], No. 3976/63. Heading H4F. [Also. in Division G2] A colour analysing system for colour television comprises a colour filter having concentric rings of different colours disposed behinda lens system 1, the beam from the lens. system. being passed. through a lens 6 having the filter on its first surface and the rays from each colour being deflected by reflectors 10, 11 which may be front surface mirrors. The coloured beams are passed into colour pick-up tubes 13, 15 and 17. It is preferred that the centre of the filter is green, the next ring red, and the outer ring blue, each ring: having an effective aperture of 18.
