Title
(EN) SYSTEM AND METHOD FOR GENERATING HIGH-LUMINANCE WINDOWS ON A COMPUTER DISPLAY DEVICE
(FR) SYSTEME ET PROCEDE DE PRODUCTION DE FENETRES A LUMINANCE ELEVEE SUR UN DISPOSITIF D'AFFICHAGE D'ORDINATEUR
Abstract
(EN) A system and method for generating high-luminance windows on a computer display device includes a video amplifier which provides video signals to a cathode ray tube, a window generator which provides a window signal to the video amplifier to generate the high-luminance window, and an automatic beam limiter which controls the beam current provided to the cathode ray tube during period of the high-luminance window.
(FR) Un système et un procédé destinés à produire des fenêtres de luminance élevée sur le dispositif d'affichage d'un ordinateur comprend un amplificateur vidéo fournissant des signaux vidéo à un tube cathodique, un générateur de fenêtres fournissant un signal de fenêtre à l'amplificateur vidéo afin de produire la fenêtre à luminance élevée, et un limiteur automatique de faisceau, lequel commande le courant du faisceau fourni au tube cathodique pendant la période de la fenêtre à luminance élevée.
