Abstract

L'invention concerne un procédé et un dispositif destinés à la photographie d'un champ du visage d'une personne dans un espace de prise de vue virtuel. L'invention peut servir à la reconnaissance, la photographie et l'analyse automatiques du champ du visage d'une personne, des dispositifs optiques de reconnaissance et de photographie et une commande d'appareil correspondante permettant, d'une part de localiser le visage ou le champ du visage de la personne et de le comparer à des caractéristiques qualitatives prédéterminées et, d'autre part de reproduire, pour une utilisation ultérieure, le champ du visage après analyse et corrections, lorsque les caractéristiques qualitatives sont suffisamment bonnes.
