Abrégé
(EN)
A fingerprint capturing method, a fingerprint capturing apparatus, an electronic device, and a storage medium are disclosed. The fingerprint capturing method may be applied to an electronic device including a touch screen. The fingerprint capturing method includes: when a luminance of a fingerprint capturing area of the touch screen is a first luminance value, adjusting the luminance of the fingerprint capturing area to a second luminance value in response to detecting a touch operation on the fingerprint capturing area; and capturing a fingerprint image corresponding to the touch operation under the second luminance value via a fingerprint sensor, wherein the fingerprint sensor is disposed below the fingerprint capturing area.

L'invention concerne un procédé de capture d'empreintes digitales, un appareil de capture d'empreintes digitales, un dispositif électronique et un support d'informations. Le procédé de capture d'empreintes digitales est appliqué à un dispositif électronique comprenant un écran tactile. Le procédé de capture d'empreintes digitales comprend les étapes suivantes consistant : lorsqu'une luminance d'une zone de capture d'empreintes digitales de l'écran tactile est une première valeur de luminance, à ajuster la luminance de la zone de capture d'empreintes digitales à une seconde valeur de luminance en réponse à la détection d'une opération tactile sur la zone de capture d'empreintes digitales ; et à capturer une image d'empreintes digitales correspondant à l'opération tactile sous la seconde valeur de luminance par l'intermédiaire d'un capteur d'empreintes digitales, le capteur d'empreintes digitales étant disposé au-dessous de la zone de capture d'empreintes digitales.
