Abstract

L'invention concerne un procédé de traitement d'images et un appareil associé. Ledit procédé est appliqué à un dispositif électronique, et une région prédéfinie (103) de l'écran (102) du dispositif électronique (101), a une fonction de reconnaissance d'empreinte digitale. Ledit procédé comprend les étapes consistant à : dans un environnement courant, acquérir au moins une image lorsque l'écran (102) est dans un état d'extinction d'écran, et déterminer une première image en fonction de l'au moins une image (S201) ; déterminer une seconde image selon la première image (S202) ; obtenir, en fonction de la deuxième image et de la première image, une troisième image où des informations d'arrière-plan sont éliminées (S203) ; déterminer des lignes fixes existant dans la région prédéfinie en fonction de la troisième image (S204) ; et bloquer les lignes fixes sur la première image pour obtenir une image cible (S205). Le procédé peut résoudre le problème de fausse reconnaissance de lignes fixes par extraction de lignes fixes, application d'un blocage de correspondance sur la région de coordonnées de celles-ci, ce qui évite ainsi une fausse reconnaissance, et améliore la précision et l'intelligence du dispositif électronique (101) effectuant un traitement d'image.
