CALIBRATION METHOD AND DEVICE FOR FINGERPRINT SENSOR AND SMART MOBILE TERMINAL

摘要

Disclosed are a calibration method and device for a fingerprint sensor and a smart mobile terminal. The method comprises: calibrating a fingerprint sensor to acquire first calibration data; using the first calibration data and existing second calibration data to capture images respectively; and, if the quality of the image captured using the first calibration data is higher, then replacing the second calibration data with the first calibration data.
