Abstract

Un système de représentation dynamique d'image comprend un appareil pour détecter une scène dynamique et un appareil pour permettre une représentation numérique dynamique réduite du nombre de pixels de la scène présentant des réductions du nombre de pixels dans des parties de la scène ne répondant pas à des critères spatiaux prédéterminés, et des réductions du nombre de pixels dans des parties de la scène ne subissant pas de modification dans le cadre de critères temporels prédéterminés.
