便携产品中的指纹识别主要是利用传感器获取指纹图像,然后进行比对(见图1)。最近,带导航(navigation)功能的产品相继出现。这些产品具有个人认证功能,其指纹传感器类似触摸屏,可以替代以往使用的开关,从而节约器件。目前,指纹传感器有电容式、电场检测式、光学式、热感式和压感
Fingerprint recognition in portable products mainly uses sensors to obtain fingerprint images and then compares them (see FIG. 1). Recently, products with navigation capabilities appeared in succession. These products have a personal authentication function, the fingerprint sensor similar to the touch screen, you can replace the switch used to save the device. Currently, fingerprint sensors have capacitance, electric field detection, optical, thermal and pressure sensitive
