Abstract
A real-time telecine system for converting motion picture film to high definition video contains a control unit comprising a database which provides complete control over all parameters associated with the film to high definition video conversion. The telecine system comprises a lamphouse which generates three monochromatic light sources wherein the light intensity for each light source is controlled independently by the control unit. Each light source contains a lamp, a variable power supply, a lens configuration and a light valve. Each lamp comprises a non-incandescent lamp such as xenon, and generates a collimated light beam. Each lens configuration contains a heat mirror, dichroic filters and a focusing lens. The dichroic filters for each light source generate a monochromatic light source by filtering the light beam. The focusing lens focuses the monochromatic light beam from each light source for input to an integrating sphere. The integrating sphere generates a polychromatic diffused light source for illuminating a film frame to generate an optical film image.
