Abstract

518,761. Colour television. HEWSON, B. T.. and LOCAN, A. May 30, 1938, No. 16063. Drawings to Specification. [Class 40 (iii)] [Also in Group XX] In colour television, there is placed both in front of the television camera and between the cathode ray oscillograph and the viewing screen a rotatable filter device carrying a plurality of colour filters, each provided with all the necessary colour selecting elements for the system in question, the colour selecting elements being of the same or substantially the same superficial area and being disposed in different spatial relationship in successive filters, and the filter device being rotated to bring a different filter into the exposure position for each successive image. The colour filters may be of the multicolour screen type, or may have two or more different colour sections arranged in different sequences, or may each comprise only a single pair of colours. Specification 518,812 is referred to.
