Claims23
A method of controlling an electronic device, the electronic device comprising a control unit, a display unit defining a first functional area, and a fingerprint sensor defining a second functional area, wherein the second functional area at least partly overlaps with the first functional area, wherein the method comprises:
- detecting, using the fingerprint sensor and the control unit, a user's finger within a portion of the second functional area of the fingerprint sensor, the portion defining a sensing area for the fingerprint sensor, the sensing area arranged at a first position within the second functional area of the fingerprint sensor;
- acquiring, at the sensing area using the fingerprint sensor, a fingerprint image of a finger of the user;
- authenticating, using the control unit, the user based on the acquired fingerprint image;
- receiving, at the control unit, a request to redefine the position of the sensing area;
- and
- determining, using the control unit, a second position for the sensing area only if the user has been successfully authenticated.
An electronic device, comprising:
- a control unit;
- a display unit defining a first functional area;
- and
- a fingerprint sensor defining a second functional area, wherein the second functional area at least partly overlaps with the first functional area,
- wherein the electronic device is adapted to:
- detect, using the fingerprint sensor and the control unit, a user's finger within a portion of the second functional area of the fingerprint sensor, the portion defining a sensing area for the fingerprint sensor, the sensing area arranged at a first position within the second functional area of the fingerprint sensor;
- acquire, at the sensing area using the fingerprint sensor, a fingerprint image of a finger of the user;
- authenticate, using the control unit, the user based on the acquired fingerprint image;
- receive, at the control unit, a request to redefine the position of the sensing area;
- and
- determine, using the control unit, a second position for the sensing area only if the user has been successfully authenticated.

A computer program product comprising a non-transitory computer readable medium having stored thereon computer program means for a control unit adapted for controlling an electronic device, the electronic device further comprising a display unit defining a first functional area, and a fingerprint sensor defining a second functional area, wherein the second functional area at least partly overlaps with the first functional area,
- wherein the computer program product comprises:
- code detecting, using the fingerprint sensor and the control unit, for a user's finger within a portion of the second functional area of the fingerprint sensor, the portion defining a sensing area for the fingerprint sensor, the sensing area arranged at a first position within the second functional area of the fingerprint sensor;
- code for acquiring, at the sensing area using the fingerprint sensor, a fingerprint image of a finger of the user;
- code for authenticating, using the control unit, the user based on the acquired fingerprint image;
- code for receiving, at the control unit, a request to redefine the position of the sensing area;
- and
- code for determining, using the control unit, a second position for the sensing area only if the user has been successfully authenticated.
