Title:
FINGERPRINT DETECTION METHOD, FINGERPRINT DETECTION APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/104659
Kind Code:
A1
Abstract:
Provided are a fingerprint detection method, a fingerprint detection apparatus and an electronic device, which can improve the performance of fingerprint detection. The method comprises: according to a predetermined exposure order, sequentially starting exposing all rows of pixels in a pixel array that is used for fingerprint detection, wherein exposure orders of two specific adjacent rows of pixels in the pixel array are not adjacent, or exposing one specific row of pixels in the pixel array twice; and reading data of each row of pixels at the end of the exposure of the row of pixels, wherein the difference between the data of the two adjacent rows of pixels or the difference between the data after the two instances of exposure of the specific row of pixels is used for determining whether a finger moves during the exposure process of the pixel array.
