Abstract
(EN)
A fingerprint recognition module, a fingerprint recognition method, and a related product. The method comprises: receiving a fingerprint collection instruction; and transmitting a charged fingerprint collection signal, a frequency of the charged fingerprint collection signal being greater than a preset frequency, the preset frequency being a switching frequency of a charger of an electronic device, and the charged fingerprint collection signal being used for collecting fingerprint image data of a user. In the method, when an electronic device is charged, noise interference of a charger to a fingerprint image can be reduced.
(FR)
La présente invention concerne un module et un procédé de reconnaissance d'empreintes digitales, et un produit associé. Le procédé consiste : à recevoir une instruction de collecte d'empreintes digitales; et à transmettre un signal de collecte d'empreintes digitales chargé, une fréquence du signal de collecte d'empreintes digitales chargé étant supérieure à une fréquence prédéfinie, la fréquence prédéfinie étant une fréquence de commutation d'un chargeur d'un dispositif électronique, et le signal de collecte d'empreintes digitales chargé étant utilisé pour collecter des données d'image d'empreintes digitales d'un utilisateur. Dans le procédé, lorsqu'un dispositif électronique est chargé, l'interférence de bruit d'un chargeur sur une image d'empreintes digitales peut être réduite.
