1. A fingerprint recognition method, performed by an electronic device comprising a first screen and a second screen, the method comprising:
obtaining first fingerprint information through the first screen;
extracting a first fingerprint feature from the first fingerprint information based on a fingerprint recognition mode corresponding to the second screen, and using the first fingerprint feature as a first pre-stored fingerprint template corresponding to the second screen;
obtaining second fingerprint information through the second screen; and
extracting a second fingerprint feature from the second fingerprint information, and determining whether the second fingerprint feature matches the first pre-stored fingerprint template; wherein
after the extracting the first fingerprint feature from the first fingerprint information based on the fingerprint recognition mode corresponding to the second screen, and using the first fingerprint feature as the first pre-stored fingerprint template corresponding to the second screen, the method further comprises:
determining the first pre-stored fingerprint template as a second pre-stored fingerprint template corresponding to the first screen in a case that a fingerprint recognition mode corresponding to the first screen is the same as the fingerprint recognition mode corresponding to the second screen; and
extracting a third fingerprint feature from the first fingerprint information based on the fingerprint recognition mode corresponding to the first screen in a case that the fingerprint recognition mode corresponding to the first screen is different from the fingerprint recognition mode corresponding to the second screen, and using the third fingerprint feature as the second pre-stored fingerprint template corresponding to the first screen.
