Abstract

Dans cette caméra de télévision, lors de la captation durant une période de trame standard, on traite une trame de lignes sans interlignage à la demi-période de ligne. D'autres traitements de signaux sont effectués avantageusement sans devoir recourir à un retard d'une période de trame pour améliorer la qualité d'image en combinant les informations de lignes physiquement directement voisines, comme une correction d'ouverture verticale ou une réduction de la scintillation d'interlignage. Ces opérations sont suivies d'un traitement du signal de façon à obtenir un signal vidéo conforme aux normes de télévision. Application : prise de vue de télévision.
