Abstract
The present invention relates to a method for determining a finger movement event on a fingerprint sensor. The method comprises to acquire signals indicative of the portion of finger detecting structures that may be touched by a finger. Based on the ratio between the signals and a total signal level, the position of the finger on the fingerprint sensing device can be determined at two different time instances. Based on the positions which may be the same, a finger movement event may be determined. The invention also relates to a corresponding fingerprint sensing device.
