Abstract
L'invention concerne un système de visée pour caméra cinématographique. L'image transmise par la lentille 10 et l'obturateur rotatif 12 est alternativement envoyée sur la pellicule 14 et sur le système de visée qui comprend une plaque 16 dont la face 16b est dépolie et dont la face 16a porte des lignes réfléchissant la lumière 40 et 42 définissant les limites du champ de visée. Ces limites sont éclairées par des lampes 24, 26 et 28 situées de l'autre côté d'un diviseur de faisceau 22 qui transmet l'image à un oculaire 34. L'éclairage des lignes de visée permet de photographier des scènes faiblement eclairées, par exemple des scènes de nuit.
