Abstract
The present invention relates to a method of enrolling a fingerprint of a user's finger, by means of an elongated fingerprint sensor having a sensing area being smaller than the fingerprint. The method comprises the steps of instructing the user to place the finger on the fingerprint sensor with a first finger orientation for achieving a first angle between a longitudinal finger axis and a longitudinal sensor axis; acquiring a partial fingerprint image for the first orientation; instructing the user to place the finger on the fingerprint sensor with a second finger orientation for achieving a second angle; acquiring a partial fingerprint image for the second finger orientation; and forming a fingerprint enrollment representation for the finger based on the partial fingerprint images for the first and second finger orientations and a relation between the first angle and the second angle.
