Abstract
Provided are a fingerprint detection apparatus and method and an electronic device, which can improve the detection and identification effect of fingerprint detection when a distance between the optical fingerprint detection apparatus and a display screen changes, thereby improving user experience. The fingerprint detection apparatus is configured to be disposed below a display screen of an electronic device, and includes: a pixel array including a plurality of groups of pixels, the plurality of groups of pixels being configured to respectively receive light signals in multiple directions to obtain multiple images; and a processing unit configured to move the multiple images for combination to form a reconstructed image, and adjust moving distances of the multiple images according to a quality parameter of the reconstructed image to form a target reconstructed image, the target reconstructed image being a fingerprint image of the finger for fingerprint identification.
