Improve fingerprint identification rate Huawei applied for patent for fingerprint identification

Huawei recently launched a brand new Huawei Mate 50 series model, which was very popular at the beginning of its launch. This mobile phone is equipped with the latest Qualcomm Snapdragon 8+processor, a 50 megapixel camera and other powerful hardware. Recently, Huawei is applying for the latest fingerprint identification patent. It can be seen that Huawei Mate 50's fingerprint identification speed is quite good. I believe many partners are interested in this, Now let's have a look with Xiao Bian!

According to the Tianyan App, on September 13, the patent of "a fingerprint identification method and electronic equipment" applied by Huawei Technologies Co., Ltd. was published. The patent abstract shows that the present application provides a fingerprint identification method and an electronic device. The method includes: the electronic device collects a first fingerprint image;

When it is judged that there is a medium on the display screen of the electronic device according to the first fingerprint image, the electronic device processes the first fingerprint image through the first image enhancement model to obtain the second fingerprint image; The number of feature points of the second fingerprint image is greater than that of the first fingerprint image;

The electronic device calculates the characteristic value of the second fingerprint image. When the similarity with the characteristic value of the preset fingerprint image is greater than the first preset value, the electronic device confirms that the fingerprint is unlocked or decrypted successfully.

This patent realizes that the electronic device detects that there is a medium between the finger and the touch screen, and processes the collected fingerprint image according to the predetermined algorithm to reduce the interference of the medium on the fingerprint image recognized by the electronic device, so as to effectively improve the fingerprint recognition rate under the screen.

The above is the introduction of Huawei's latest fingerprint identification patent. This time, the fingerprint identification function of Huawei mate 50 series models is quite good. It is not only fast, but also accurate enough. Partners who want to experience this function can consider starting with this mobile phone to try it!
