Fingerprint inputting method and related device

An electronic device comprising:

• a display screen, configured to display a setting interface of fingerprint input comprising a button of adding fingerprint function and to display a guiding interface of fingerprint input;
• an under-screen fingerprint module corresponding to a predetermined region of the display screen, configured to obtain at least one screen image while a user finger is not pressing a fingerprint identification region in response to detecting an instruction on the fingerprint adding function, and configured to obtain a plurality of fingerprint images while the user finger is pressing the fingerprint identification region, wherein the fingerprint identification region comprises the predetermined region;
• a processor;
• a memory, storing one or more programs executable by the processor to perform at least one operation comprising:
• generating a fingerprint model according to the at least one screen image and the plurality of fingerprint images;
• wherein the at least one screen image comprises only one screen image and the generating the fingerprint model comprises:
• determining a reference image for filtering out a non-fingerprint information of the predetermined region and the non-fingerprint information comprises at least one of a dirty stain and a foreign object;
• obtaining a reference fingerprint image by filtering out a noise factor from each of the plurality of fingerprint images according to the reference image;
• and
• generating the fingerprint model according to a fingerprint model algorithm and a plurality of the reference fingerprint images.

A non-transitory computer-readable storage medium storing computer procedures for electronic data interchange, wherein the computer procedures are executable by a computer to perform at least one operation comprising:

• generating a fingerprint model according to at least one screen image and a plurality of fingerprint images;
• wherein the at least one screen image is obtained by an under-screen fingerprint module while a user finger is not pressing a fingerprint identification region in response to detecting an instruction on a button of adding fingerprint function that is displayed on a display screen of the computer;
• wherein a plurality of fingerprint images are obtained by the under-screen fingerprint module while the user finger is pressing a fingerprint identification region of the display screen;
• wherein the fingerprint identification region corresponds to the under-screen fingerprint module;
• and
• wherein the computer procedures are executable by the computer to perform:
• generating a reference image for filtering out a noise factor according to the at least one screen image, wherein the noise factor comprises a non-fingerprint information of the predetermined region and the non-fingerprint information comprises at least one of a dirty stain and a foreign object;
• obtaining a reference fingerprint image by filtering out a noise factor from each of the plurality of fingerprint images according to the reference image;
• and
• generating the fingerprint model according to a fingerprint model algorithm and a plurality of the reference fingerprint images.
