Abstract

1370242 Colour television MAGNAVOX CO 11 Feb 1972 [8 March 1971] 6591/72 Heading H4F A colour television camera such as described in Specification 1,322,041, in which two colour filter gratings are used to modulate the light falling on to the camera tube face, the grating lines of the two filters being arranged in different directions transverse to the scan direction so as to produce a different phase relationship between the modulated components of the tube output in successive lines of scan, utilizes a spatial frequency filter in the optical path from the subject to the filter gratings to minimize the effect of sharp transistors and of repetitive patterns in the subject corresponding to the grating spacings.
