Title (EN) OPTIMIZED RED-EYE FILTER METHOD AND APPARATUS INVOLVING SUBSAMPLE REPRESENTATIONS OF SELECTED IMAGE REGIONS
(FR) PERFORMANCE OPTIMISEE ET PERFORMANCE D'UN APPAREIL ET PROCEDE DE SUPPRESSION DU PHENOMENE « OEIL ROUGE »
Abstract:
(EN) A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the read area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.
(FR) L'invention porte sur un appareil photo numérique à flash intégré stockant et affichant une image numérique. Dans certaines conditions, une photographie au flash prise avec cet appareil photo peut occasionner un phénomène oeil rouge imputable à la réflexion à l'intérieur de l'oeil du sujet. L'invention porte sur un appareil numérique possédant un filtre anti-oeil rouge qui recherche dans l'image mise en mémoire le phénomène oeil rouge et la modifie afin de supprimer ce phénomène en convertissant les rouges en en noir. Le processus de modification de l'image entre en fonction lorsque les conditions de prise d'une photo annoncent le phénomène oeil rouge. La modification est soumise à une analyse anti-faux qui pousse l'examen dans la couronne autour de l'oeil rouge à la recherche des traits marquants de l'oeil du sujet. On peut accélérer et améliorer les processus de détection et de correction en faisant porter le traitement sur des versions de sous-échantillon de l'image, en cas de besoin.
