Abstract

Disclosed is a method for real-time color masking, Accord- ing to this method, color image input 8 is split into its separate color components by means of a beam splitter 9 and color filters 12 and 13, Color filters 12 and 13 can cor- respond to different primary colors such as green and blue, respectively, A green image 1g is thereafter focused onto a gamma Ruticon type imaging member 10 and a blue image 'b onto a second gamma Ruticon type imaging member 11, Colli- mated light 'A is reflected off the reflective surface of Ruticon imaging member 10, The image corresponding to the zero diffraction order light (negative image) created by reflection from the surface of imaging member 10 is pro- jected onto the reflective surface of imaging member 11 in registration with image 1b~ The higher order reflections of the product of the negative image of 'b and tbe positive image, 'Mi corresponds to a color masked yellow toned component of the original image,
