Abstract
(EN)
A fingerprint acquisition method and an electronic device. An under-screen fingerprint module is provided in a preset region of a display screen of the electronic device. The method comprises: acquiring at least one first fingerprint image when the brightness of the display screen is first brightness, and acquiring at least one second fingerprint image when the brightness of the display screen is second brightness, so as to obtain at least two fingerprint images, the first brightness is less than the second brightness (S201); and determining a target fingerprint image according to the at least two fingerprint images (S202). According to the method, the problem of light interference can be solved, the accurate fingerprint is acquired, the unlocking success rate is further improved, and the accuracy and intelligence of fingerprint acquisition of the electronic device are improved.

L’invention concerne un procédé d'acquisition d’empreinte digitale et un dispositif électronique. Un module d'empreinte digitale sous-écran est disposé dans une région prédéfinie d'un écran d'affichage du dispositif électronique. Le procédé consiste à : acquérir au moins une première image d'empreinte digitale lorsque la luminosité de l'écran d'affichage est une première luminosité et acquérir au moins une seconde image d'empreinte digitale lorsque la luminosité de l'écran d'affichage est une seconde luminosité, de façon à obtenir au moins deux images d'empreinte digitale, la première luminosité est inférieure à la seconde luminosité (S201) ; et déterminer une image d'empreinte digitale cible selon les au moins deux images d'empreinte digitale (S202). Selon le procédé, le problème d'interférence de lumière peut être résolu, l'empreinte digitale précise est acquise, le taux de réussite de déverrouillage est encore amélioré et la précision et l'intelligence d'acquisition d'empreinte digitale du dispositif électronique sont améliorées.
