Claims15
An electronic device, comprising:
- a display unit configured to display a first graphical user interface (GUI);
- a first user input device comprising a fingerprint sensor configured to capture a fingerprint image of a finger of a user, and
- a control unit configured to control the operation of the fingerprint sensor, wherein the control unit is configured to:
- detect the user's finger at the first user input device;
- arrange, in response to the finger being detected, the fingerprint sensor in a reduced information capturing mode,
- acquire, when in the reduced information capturing mode, a first and a second partial fingerprint image,
- determine a sensitivity setting of the fingerprint sensor based on the first and the second partial fingerprint image, and
- determine, based on the first and the second partial fingerprint image, a level of movement of the finger at the fingerprint sensor,
- if the level of movement is below a predetermined threshold:
- arrange the fingerprint sensor in a fingerprint authentication capturing mode,
- apply the determined sensitivity setting to the fingerprint sensor, and
- acquire, when in the fingerprint authentication capturing mode, a fingerprint image for allowing authentication of the user's finger, if the level of movement is above the predetermined threshold:
- determine a direction of movement of the finger over the fingerprint sensor based on the first and the second partial fingerprint image.
A method of controlling an electronic device, the electronic device comprising a display unit configured to display a first graphical user interface (GUI), a first user input device comprising a fingerprint sensor configured to capture a fingerprint image of a finger of a user, and a control unit configured to control the operation of the fingerprint sensor, wherein the method comprises:
- detecting the user's finger at the first user input device;
- arranging, in response to the finger being detected, the fingerprint sensor in a reduced information capturing mode;
- acquiring, when in the reduced information capturing mode, a first and a second partial fingerprint image,
- determining a sensitivity setting of the fingerprint sensor based on the first and the second partial fingerprint image, and
- determining, based on the first and the second partial fingerprint image, a level of movement of the finger at the fingerprint sensor,
- if the level of movement is below a predetermined threshold:
- arranging the fingerprint sensor in a fingerprint authentication capturing mode,
- applying the determined sensitivity setting to the fingerprint sensor, and
- acquiring, when in the fingerprint authentication capturing mode, a fingerprint image for allowing authentication of the user's finger,
- if the level of movement is above the predetermined threshold:
- determining a direction of movement of the finger over the fingerprint sensor based on the first and the second partial fingerprint image.
