Abstract

L'invention concerne des systèmes, un équipement et des procédés permettant un réglage amélioré de couleur dans des présentations projetées. Cet équipement, ces systèmes et ces procédés sont destinés à faire correspondre l'équilibre couleur de chaque affichage, y compris la couleur primaire de l'affichage. L'invention concerne aussi un autre équipement, d'autres systèmes et d'autres procédés destinés à la correction d'une variation de couleur fonction d'un champ à travers le champ d'un projecteur à base de modulateur spatial de lumière (SLM).
