A fingerprint-based navigation method using a finger navigation system comprising fingerprint sensing circuitry and navigation control circuitry. The method comprises the steps of: acquiring a series of navigation sequences of fingerprint images, and for each navigation sequence in the series of navigation sequences: determining an estimated momentary finger movement based on the navigation sequence of fingerprint images; determining at least one fingerprint image parameter value indicative of a fingerprint image status based on at least one fingerprint image in the navigation sequence of fingerprint images; and evaluating the fingerprint image status. The method further comprises the steps of determining a fingerprint sensing circuitry setting based on the evaluation; and providing the fingerprint sensing circuitry setting to the fingerprint sensing circuitry only during a time period between acquisition of a final fingerprint image in one navigation sequence and acquisition of a first fingerprint image in another, directly succeeding, navigation sequence. |
