A TELECINE SYSTEM FOR PRODUCING VIDEO SIGNALS FROM FILM

摘要

In a telecine equipment variations in exposure of the film can be disturbing to viewers. This invention provides a compensation for such variations which may be effected within the time of a small number of television field scans and employs a peak signal detector for determining during operation peak signal amplitude occurring during a predetermined number of television fields and control means, which may vary the gain of the camera or video signal processing amplifier, operable for a subsequent predetermined number of fields for applying correction for any departure from a desired peak signal level.
