Title (EN) METHOD AND APPARATUS FOR IMPROVING SIGNAL TO NOISE RATIO IN A TELECINE MACHINE
(FR) PROCEDE ET APPAREIL SERVANT A AMELIORER LE RAPPORT SIGNAL-BRUIT DANS UN TELECINEMA
Abstract:
(EN) A method and apparatus is disclosed for operating CCD sensors of a telecine machine at full well potential during a conversion mode of operation and at 1/2 full well potential during shuttle mode operations. The disclosed method and apparatus optimized the signal-to-noise S/N ratio during the conversions operation.
(FR) On décrit un procédé et un appareil servant à faire fonctionner les détecteurs à charge couplée d'un télécinéma à plein potentiel de puits pendant un mode de conversion, et à la moitié du plein potentiel de puits pendant un mode navette. Le procédé et l'appareil décrits optimisent le rapport signal-bruit pendant le mode de conversion.
