Abstract
Embodiments of the present application provide a method for fingerprint identification, which could reduce power consumption of a display screen in a fingerprint identification process. The method including: acquiring a pressing region in which a finger performs a fingerprint pressing operation in a fingerprint capturing region; and determining an illuminating region of a display screen according to the pressing region, where light emitted by the display screen in the illuminating region is used for fingerprint identification, and an area of the illuminating region is smaller than an area of the fingerprint capturing region.
Claims18
A method for fingerprint identification, comprising:
- acquiring a pressing region in which a finger performs a fingerprint pressing operation in a fingerprint capturing region;
- and
- determining an illuminating region of a display screen according to the pressing region, wherein light emitted by the display screen in the illuminating region is used for fingerprint identification, and an area of the illuminating region is smaller than an area of the fingerprint capturing region.
An apparatus for fingerprint identification, comprising:
- an acquisition unit configured to acquire a pressing region in which a finger performs a fingerprint pressing operation in a fingerprint capturing region;
- and
- a determining unit configured to determine an illuminating region of a display screen according to the pressing region, wherein light emitted by the display screen in the illuminating region is used for fingerprint identification, and an area of the illuminating region is smaller than an area of the fingerprint capturing region.
A terminal device, comprising an apparatus for fingerprint identification, wherein the apparatus comprises:
- an acquisition unit configured to acquire a pressing region in which a finger performs a fingerprint pressing operation in a fingerprint capturing region;
- and
- a determining unit configured to determine an illuminating region of a display screen according to the pressing region, wherein light emitted by the display screen in the illuminating region is used for fingerprint identification, and an area of the illuminating region is smaller than an area of the fingerprint capturing region.
