  • Patent number: 5361106
    Abstract: A method and apparatus for providing high definition cinema pictures involves the use of a plurality of filters, each capable of transmitting light in a different wavelength band, to form a plurality of superimposed image components on the cinema film during a single frame period. A similar filtering operation is carried out when the film is projected to reconstitute the original colour image. Thus, if two filers are used at each stage twice the normal frame rate can be achieved whilst still using a camera and projector operating at the normal rate.
