Abstract
Signal vidéo comprenant une adresse de données indiquant si le signal provient à l'origine d'une image optique prise par une caméra ou une caméra vidéo. Ces données sont utilisées (140, 136) sur un écran de projection recevant un signal vidéo entrelacé et comprenant un modulateur de lumière spatiale (110) se présentant sous forme d'un système à miroir déformable (SMD) de manière à faire varier de manière sélective le mode d'interpolation et le mode de mise à jour utilisé dans le SMD. Dans un mode d'interpolation, un bloc complet de données d'images est interpolé à partir d'un des champs vidéo entrelacés d'entrée, de manière à réduire les effets artificiels du mouvement (Fig. 12). Dans un mode de mise à jour (mode B) les lignes impaires sont mises à jour au début d'un champ et les lignes paires sont mises à jour au début du champ suivant, et ainsi de suite (Fig. 9).
