An Automatic Portable Telecine Camera.

Abstract

This Memorandum describes an automatic portable telecine system that enables television records to be transferred to 16 mm film for analysis or demonstration purposes. A television display is filmed by a modified 16 mm cine camera driven by a control unit in which the camera supply voltage is derived from the field synchronisation pulses of the video signal. Automatic synchronisation of the camera mechanism is achieved over a wide range of television field frequencies and the shutter bar effect, resulting from exposure time and camera speed errors, in non-synchronised systems, is eliminated.
