Abstract

L'invention concerne les caméras équipées d'un témoin lumineux pour signaler aux personnes filmées que la caméra tourne. Pour réduire la consommation de courant de ce témoin, éliminer le risque de reflets lumineux sur le film et rendre le témoin plus clairement perceptible, la source lumineuse du témoin clignote, étant allumée seulement quand l'obturateur est fermé Cette source lumineuse peut être une diode luminescente 6 disposée à l'intérieur de l'objectif 1 à 4 et dont le circuit d'alimentation électrique 7 comprend un interrupteur 8 couplé aux mouvements de l'obturateur. Un interrupteur supplémentaire 9 peut être prévu pour signaler la fin du film.
