Abstract
A method for determining a finger motion on a fingerprint sensor comprising a sensing area, the method comprises: receiving a finger on the sensing area of the fingerprint sensor; when an amount of sensor area coverage caused by the finger touching the sensing area is below a coverage threshold, acquiring images of a first type using a first image acquisition setting with the fingerprint sensor, when the amount of sensor area coverage is equal to or exceeds the coverage threshold, acquiring images of a second type using a second image acquisition setting with the fingerprint sensor, and determining a present motion of the finger on the fingerprint sensor based on the first type of images or the second type of images depending on a present amount of sensor area coverage.
