    Abstract: A method of classifying a finger touch in respect of a finger pressure on a surface of a fingerprint sensor, comprising the steps of: receiving, on the surface of the fingerprint sensor, a finger having a fingerprint topography; acquiring a first time-sequence of fingerprint images; determining a reference value of at least one image-related parameter indicative of a compression of the fingerprint topography, based on at least one fingerprint image in the first time-sequence of fingerprint images; acquiring a second time-sequence of fingerprint images; determining a test value of the at least one image-related parameter based on at least one fingerprint image in the second time-sequence of fingerprint images; and classifying the finger touch based on a relation between the test value and the reference value.

    Abstract: A method for providing user input on an electronic device comprising a fingerprint sensor comprising an array of sensing elements. Acquiring partial fingerprint images of a finger touching a finger touch surface of the fingerprint sensor from at least two sub-groups of sensing element. Determining a respective force value indicative of a force applied on the finger touch surface at each of the sub-groups of sensing elements when the partial fingerprints were acquired, based on the partial fingerprint images acquired from the respective sub-group of sensing elements. Determining a force value difference between a pair of the determined force values. Determining a user input based on the determined force value difference, and based on the relative location between the sub-groups of sensing elements in the pair associated with the force value difference.

    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.

    Abstract: The present invention relates to a method for transitioning a device controller comprised with an electronic device from an at least partly inactive mode to an at least partly active mode, wherein the method comprises: determining the area portion of a finger detecting structure being touched by an object; determining a force applied on the fingerprint sensing device. When the area portion of the finger detecting structure being touched by the object exceeds a predetermined threshold area portion, and the force exceeds a predetermined threshold force value, transitioning, using the pre-processing module, the device controller from the at least partly inactive mode to the at least partly active mode. The invention also relates to such an electronic device.

    Abstract: The present disclosure relates to a method performed in an electronic device comprising a fingerprint sensor. For each of a plurality of consecutive sub-templates, the method comprises determining that a fingerprint is in proximity to the fingerprint sensor as part of an interaction with the fingerprint sensor; extracting the sub-template from a captured image of the fingerprint; obtaining an indication about whether the fingerprint was in proximity to the sensor also during a time period prior to the determining; defining the interaction as a slide interaction if the fingerprint was in proximity or as a touch interaction if the fingerprint was not in proximity; and based on whether the interaction is defined as a slide interaction or a touch interaction, advancing an enrolment progress. When the enrolment progress is above a predetermined threshold, a template compiled from the sub-templates is enrolled.
