ABSTRACT
The trichromatic theory of colour synthesis requires that initially the subject colours are analysed into suitable red, green and blue components as signals for recording and subsequent re-combination. Colour video cameras, including still video types, use various sequential or simultaneous colour separation or ‘splitter’ systems for analysis. The asymmetric prism block system gives a non-parallel arrangement of three image tubes, influencing camera size and shape. A general configuration of the optics in a three-chip camera. The transfer from cine film to video tape may also take place in a multiplexer chain involving aerial image projection, The transfer of a complete film requires a more specialist complex form of optical telecine system. Visual and audio information may be stored optically on a flat disc for subsequent readout by a laser scanning system and conversion into a digital video signal.
