Abstract
Disclosed herein includes a method, an apparatus, a display device and storage medium storing computer executable instructions for fingerprint recognition. The method may comprise turning on a first subset of a plurality of light sources located on an apparatus, capturing a first fingerprint acquisition frame using a plurality of image sensors on the apparatus, turning on a second subset of the plurality of light sources, and capturing a second fingerprint acquisition frame using the plurality of image sensors. The first fingerprint acquisition frame may include a first set of valid image zones and a first set of invalid image zones. The second fingerprint acquisition frame may include a second set of valid image zones and a second set of invalid image zones. The second set of valid image zones at least partially covers areas of a finger touching interface different from the first set of valid image zones.
