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 film transport sub-system, camera sub-system, rotating shutter and lamphouse. To convert a motion picture film to high definition video, the motion picture film is advanced, by the film transport sub-system, a single frame at a time during a pulldown period, and the film is held steady during a register period. The lamphouse emanates a single diffused light source to illuminate the film frame to generate an optical film image. The rotating shutter permits exposure of the optical film image to the camera sub-system in a 3-2 pulldown arrangement. Values for controlling the lamphouse light intensity are stored in the database and are subsequently retrieved for film to video conversion. In addition, color correction parameters associated with the motion picture film are stored in the database such that the color correction parameters are used as an initial starting point for the calibration of the telecine system.
