Color tv film reproduction system compatible with diffraction process color projection systems
摘要:
This disclosure depicts improved color television film reproduction systems and methods for displaying either conventional color transparency cine film, or cine records on which color separation information is stored as signals modulating separately detectable spatial carriers. The illustrated system comprises, inter alia, novel light source means for producing a plurality of highly spatially coherent light sources and a source of less coherence, and means employing the source of less coherence for establishing a wideband luminance channel through the system. The disclosed system further includes novel spatial filtering means and methods for enabling detection of red, blue, green, and luminance information without the need for spectral filtering in either the projector or camera stages.
