Abstract
A method for detecting fingerprints implemented in an electronic device includes detecting whether a display device is being pressed by at least one finger of a user according to signals of a pressure sensing device. If the display device is being pressed by the at least one finger of the user, controlling a fingerprint acquiring device to acquire fingerprint images of the at least one finger of the user and controlling a positioning device to acquire location information of the electronic device. The fingerprint images of the at least one finger of the user and the location information of the electronic device can be uploaded by the electronic device to a fingerprint database for fingerprint recognition.
Claims9
An electronic device comprising:
- at least one processor;
- and
- a storage device coupled to the at least one processor and storing instructions for execution by the at least one processor to cause the at least one processor to:
- detect whether a display device is being pressed by at least one finger of a user according to signals of a pressure sensing device;
- determine, in response that the display device is being pressed by the at least one finger of the user, an area which is being pressed by the at least one finger of the user of the display device by acquiring a coordinate range of the area of the display device which is being pressed;
- control a fingerprint acquiring device to emit a light beam to the area which is being pressed by the at least one finger of the user according to the coordinate range;
- control the fingerprint acquiring device to acquire fingerprint images of the at least one finger of the user;
- control a positioning device to acquire location information of the electronic device;
- and
- upload the fingerprint images of the at least one finger of the user and the location information of the electronic device to a fingerprint database for fingerprint recognition.
