Abstract:
(EN) A capacitive sensing system (10), comprising a pixel matrix (102), used for sensing a plurality of voltage change values generated by a fingerprint press; and a correction unit (108), coupled to the pixel matrix (102) and used for generating a control signal according to the plurality of voltage change values so as to correct the plurality of voltage change values of the pixel matrix (102). The capacitive sensing system (10) has the advantages of improving consistency of voltage change values detected by a pixel unit and reducing the generating of distortion conditions.
(FR) L'invention concerne un système de détection capacitive (10), comportant une matrice de pixels (102), servant à détecter une pluralité de valeurs de changement de tension générées par une pression d'empreintes digitales; et une unité de correction (108), couplée à la matrice de pixels (102) et servant à générer un signal de commande en fonction de la pluralité de valeurs de changement de tension de façon à corriger la pluralité de valeurs de changement de tension de la matrice de pixels (102). Le système de détection capacitive (10) a pour avantages d'améliorer la cohérence de valeurs de changement de tension détectées par une unité de pixel et de réduire la génération de conditions de distorsion.
(ZH) 一种电容感测系统(10),其中,包括一像素矩阵(102),用来感测一指纹按压所产生的多个电压变化值;以及一校正单元(108),耦接至所述像素矩阵(102),用来根据所述多个电压变化值产生的一控制信号,以校正所述像素矩阵(102)的所述多个电压变化值。该电容感测系统(10)具有改善像素单元所侦测的电压变化值的一致性的情况,并且降低失真情况产生的优点。
