Abstract
A color image projecting apparatus having three cathode ray tubes which produce different respective color images and including two projecting lenses. A first primary color image reproduced on a first cathode ray tube is projected on a screen through a first projecting lens, and second and third primary color images reproduced on second and third cathode ray tubes, respectively, are synthesized by a dichroic mirror and then projected on the screen through a second projecting lens. In this case, the projecting axes of the first and second projecting lenses are arranged to converge two images passed therethrough on the screen.
Claims6
A color image projecting apparatus comprising:
- a first cathode ray tube for producing a first primary color image;
- first projecting lens means disposed in front of said first cathode ray tube and arranged to project said image along a first optical axis onto a screen;
- a second cathode ray tube for producing a second primary color image;
- a third cathode ray tube for producing a third primary color image and disposed at right angles to said second cathode ray tube;
- a dichroic mirror disposed in front of said second and third cathode ray tubes to receive said images in said second and third primary colors and synthesize therefrom a two color image;
- and second projecting lens means disposed to receive said two color image and project said two color image along a second optical axis intersecting said first optical axis at an acute angle at said screen, said two color image conforming in shape to said first primary color image projecting on said screen.
