摘要：The present invention relates to a fingerprint sensing device comprising anarray of sensing elements; readout circuitry connected to the array of sensing elements;and finger detecting circuitry for detecting if a finger candidate is touching the sensingsurface of the fingerprint sensing device. The fingerprint sensing device is controllablebetween an active state and an inactive state. When the fingerprint sensing device is in theinactive state, the finger detecting circuitry is configured to provide a finger lost signalfor indicating when the finger candidate no longer touches the sensing surface of thefingerprint sensing device.
