Abstract
Certains modes de réalisation de la présente invention utilisent le traitement d'image numérique pour réduire la résolution différentielle entre des séparations ou des images dans des cadres d'images, telles que, par exemple, les lumières parasites rouges. Un emplacement dans l'image rouge peut être sélectionné à l'aide d'informations issues d'une autre image. L'emplacement sélectionné peut être modifié à l'aide des informations issues de cette autre image. La sélection peut consister à comparer des caractéristiques d'un bord dans la première image à des caractéristiques d'un bord correspondant dans l'autre image. La modification peut également consister à réaliser des transformations par ondelettes des deux images et à copier certains coefficients (ou une fonction de ces coefficients) produits par l'application de la transformation à la seconde image aux coefficients produits par l'application de la transformation à la première image. Les coefficients copiés peuvent être associés à l'emplacement sélectionné. D'autres techniques proposent des variations par rapport aux modes de réalisation décrits ci-dessus qui peuvent être appliquées à d'autres domaines.
