Title
(EN) REAL-TIME VIDEO DYNAMIC RANGE ANALYSIS
(FR) ANALYSE DE PLAGE DYNAMIQUE DE VIDÉO EN TEMPS RÉEL
Abstract
(EN)
A video analyzer measures and outputs a visual indication of a dynamic range of a video signal. The video analyzer includes a video input to receive the video signal and a cumulative distribution function generator generates a cumulative distribution function curve from a component of the video signal. A feature detector generates one or more feature vectors from the cumulative distribution function curve and a video dynamic range generator produces a visual output indicating a luminance of one or more portions of the video signal.
(FR)
Un analyseur vidéo mesure et délivre en sortie une indication visuelle d'une plage dynamique d'un signal vidéo. L'analyseur vidéo comprend une entrée vidéo pour recevoir le signal vidéo et un générateur de fonction de distribution cumulative génère une courbe de fonction de distribution cumulative à partir d'un composant du signal vidéo. Un détecteur de caractéristiques génère un ou plusieurs vecteurs de caractéristiques à partir de la courbe de fonction de distribution cumulative et un générateur de plage dynamique vidéo produit une sortie visuelle indiquant une luminance d'une ou de plusieurs parties du signal vidéo.
