Abstract: 536,327. Colour photography and kinematography ; optical systems. MORRISON, W. L. H. Aug. 31, 1939, No. 10392/38. [Classes 97 (i) and 98 (ii)] Colour component images for additive projection are produced in a row on a film 15, Fig. 3, in a tricolour camera comprising an objective 14 provided with a hood 10 having a rectangular aperture restricting the object field to that imaged on a picture area of the film, a multifaceted dividing system g comprising a series of juxtaposed members each consisting of a planeparallel element 2 which transmits part of the beam from the objective without deflection and two prism elements 1, 3 deflecting two other parts of the beam in opposite directions, colour filters 6, 7, 8 on the faces of the elements, and similar colour filters 20, 21, 22 in front of the film gate apertures. Component positive images produced therefrom are projected in the reverse direction through similar apparatus to form images in superimposition on the viewing screen. To permit focusing movement of the camera objective 14 and attached dividing system g without disturbing the incidence of the divided beams on the film 15, a similar system of three elements 26, 27, 28 is provided at a fixed distance from the system g. When it is desired to take ordinary black-and-white pictures, the filters 20, 21, 22 are replaced by a gate mask, the dividing system is removed, and the objective 14 is displaced to centre it with any one of the gates, 11, 12, 13. In a modified camera, the system 26, 27, 28 is omitted, and the system g is mounted at a fixed distance from the film gates. The projector for the positives 50, Fig. 5, includes prisms 34, 35, 52, 53 to ensure even illumination of the three components, and systems 1, 3 and 54, 55 similar to those of the dividing system shown in Fig, 3. together with fixed mirrors 43, 43a, 44 and adjustable mirrors 45, 46 to ensure correct superimposition on the screen of the images projected by the lens 42. Colour filters 36, 37, 38 are provided adjacent to the film, and similar filters on the faces of the system 1, 2, 3. In a modified projector, the system 54, 55 and the filters on the faces of the system 1, 2, 3 are omitted, and opaque partitions are provided extending between the filters 36, 37 38 and the system 1, 2, 3 to prevent overlap of the three component beams.
