Abstract
The present disclosure relates to a fingerprint recognition method, a fingerprint recognition device and an electronic device, wherein the fingerprint recognition method comprises: an obtaining step of obtaining a capacitance detection value corresponding to each sensing electrode in a sensing electrode array; a calculation step of calculating a difference value between a first capacitance detection value corresponding to a first sensing electrode and a second capacitance detection value corresponding to a second sensing electrode, wherein the first sensing electrode and the second sensing electrode are adjacent to each other in the sensing electrode array; a type determination step of determining a fingerprint type detection result of the first sensing electrode and a fingerprint type detection result of the second sensing electrode according to the difference value; and a recognition step of recognizing the fingerprint according to the fingerprint type detection results.
