Abstract

L'invention corrige les défauts de visualisation dus aux disparités entre les luminophores d'un dispositif de visualisation. La correction se fait par traitement d'image. L'invention propose un procédé de visualisation d'une séquence d'images vidéo sur un dispositif à luminophore comportant au moins deux types de luminophores ainsi que le dispositif comportant les moyens de mise en oeuvre de ce procédé. La correction se fait en calculant une image intermédiaire entre deux images successives, puis en visualisant sur un type de luminophore l'une des deux images successives et simultanément sur un autre type de luminophore l'image intermédiaire.
