Abstract

274,804. Chromo Filmges. July 22, 1926, [Convention date]. Colour kinematography. - A colour screen for use in projecting colour-record images comprises concentric annular filter sectors separated by opaque sectors D, one set of filters containing one more colour than the other set. The screen is used in projecting images taken in pairs through colour screens A, B, C so as to produce colour-record images in alternate groups A, B and A, C. As shown in Fig. 3, the screen used in projecting comprises an inner set of filters having colours A, B and A, C. and an outer set having colours B, C, additional opaque sectors being provided. The filters may also be arranged as shown in Fig. 4. Colour screens are described comprising inner annular sectors of the colour A, and outer annular sectors of the colours B and C in alternation, with and without additional opaque sectors.
