Abstract:
A method and an apparatus for determining existence of a foreign material on a surface of a fingerprint sensor of a terminal are provided. The method includes the following. A current capacitance value of the fingerprint sensor of the terminal is obtained. A first difference between the current capacitance value and a preset capacitance reference value is calculated. Determine that the foreign material is present on the surface of the fingerprint sensor when the first difference is within a preset foreign-material threshold range. The preset capacitance reference value is a capacitance value tested with no foreign material on the surface of the fingerprint sensor before leaving the factory and is stored in a system in advance. The preset foreign-material threshold range is set in advance according to experimental data of capacitance-change tests performed on the fingerprint sensor when different conductive foreign materials are on the surface of the fingerprint sensor.

Claim (Index 9):
The apparatus of  claim 6 , wherein the first foreign-material removing unit configured to increase the temperature of the fingerprint sensor is configured to:\n increase a power of the fingerprint sensor to increase the temperature of the fingerprint sensor; or control a heating device corresponding to the fingerprint sensor to heat the fingerprint sensor to increase the temperature of the fingerprint sensor.
