On December 18, Huawei recently published a patent for "fingerprint recognition method and its electronic devices and media", patent number CN113807141A.
According to the data of the enterprise investigation, the application involves the field of intelligent terminal technology, especially a fingerprint recognition method, medium and electronic equipment. The method of the application comprising obtaining the capacitance value information of the hand to which the finger belongs to the user is fingerprinted when fingerprinting the electronic device is collected by the capacitive sensor of the electronic device.
It is understood that the fingerprint recognition method of the application can collect the capacitance information of the user's finger and the hand to which the finger belongs, and collect the optical fingerprint image of the user's finger through the optical fingerprint sensor, and then combine the capacitance information and the optical fingerprint image for fingerprint recognition authentication, thereby improving the efficiency of terminal fingerprint recognition.
