Abstract
478,058. Colour kinematography. PIRGO, A. HELM-, and PUSZET, J. May 8, 1936, No. 13107. [Classes 97 (i) and 98 (ii)] Colour kinematograph pictures are taken and projected in pairs, each pair being projected on the screen simultaneously in superimposed relationship, and one pair is taken and projected through colour filters, fI and #II of colours of wavelengths substantially 500ÁÁ and 605ÁÁ, and the succeeding pair through colour filters fI<1> and fII<1> of colours of wavelengths substantially 640ÁÁ and 430ÁÁ. The pairs of pictures may comprise identical or stereoscopic views. The arrangement of the pictures may be as shown in Fig. 2, or as shown in Fig. 3, with the pictures of each pair staggered longitudinally and the provision of a sound track. The filter arrangement may comprise fixed filters c, d, combined with a movable three-window filter a, b, a, Fig. 4, reciprocated vertically. In an example the filters fI, fI<1>, fII and fII<1> may be green, red, orange-yellow and blue respectively.
