Abstract

Apparatus for processing a polychromatic optical beam for display on a color television receiver employs an optical splitter that divides an incident beam into a sub-beam responsive to luminance and into two single-color sub-beams. The splitter employs a beam splitting element, a reflective filter, and an absorbent filter. Converter elements convert the three sub-beams into corresponding electrical signals, and electronic circuits combine them to produce a composite signal having the format of chrominance and of luminance signal components standard for color television display. A consumer product for the home display of motion pictures on a color television receiver advantageously employs the foregoing construction.
