Abstract

385,141. Colour photography. ROUX, L. H., 16, Avenue Victor Hugo, Vanves, Seine, France. March 4, 1932, No. 6553. Convention date, March 4, 1931. [Class 97 (i).] In apparatus for colour photography or kinematography, of the kind comprising a main objective A and a number of secondary objectives F1, F2 each forming an image of the object photographed, a lens E is placed immediately in front of the secondary objectives, this lens having its principal focus in the plane B of the image formed by the objective A, so that the rays entering the secondary objectives are parallel. A field lens D may be included. The apparatus used for projecting the colour images is the reverse of that shown.
