摘要
A method for detecting finger-on or finger-off, including: detecting whether a sensing capacitance value of a sensing signal is higher than a high threshold or lower than a low threshold; and when the sensing capacitance value of the sensing signal is higher than the high threshold, determining that a finger is placed on the fingerprint sensing device and adjusting the high threshold and the low threshold according to the sensing capacitance value and a compensation value, and when the sensing capacitance value of the sensing signal is lower than the low threshold, determining that a finger is removed from the fingerprint sensing device and adjusting the high threshold and the low threshold according to the sensing capacitance value and the compensation value.
