Abstract

L'invention concerne un procédé d'affichage de région de reconnaissance d'empreinte digitale, et un terminal mobile. Un écran tactile du terminal mobile possède une fonction de reconnaissance d'empreinte digitale. Le procédé consiste à : détecter une opération de tapotement d'un doigt dans une région de reconnaissance d'empreinte digitale ; déterminer la taille d'une région de contact entre le doigt et l'écran tactile ; et conformément à la taille de la région de contact entre le doigt et l'écran tactile, ajuster la taille de la région de reconnaissance d'empreinte digitale et/ou afficher la région de reconnaissance d'empreinte digitale. Puisque le terminal mobile ajuste dynamiquement la taille d'une région de reconnaissance d'empreinte digitale, le taux de réussite de reconnaissance d'empreinte digitale est amélioré, et la consommation d'énergie de mise en évidence de la région de reconnaissance d'empreinte digitale est réduite.
