METHOD OF REGISTERING FINGERPRINT, METHOD OF PERFORMING OPTICAL FINGERPRINT RECOGNITION AND ELECTRONIC DEVICE

Systems and methods are described for registering a fingerprint based on optical fingerprint recognition. A fingerprint recognition window is displayed and a fingerprint frequency of a user fingerprint is analyzed based on reflected light received through the fingerprint recognition window using a fingerprint recognition sensor driven by a pixel binning scheme based on a first binning size. The first binning size may be evaluated based on the fingerprint frequency. If the first binning size is not appropriate for registering the user fingerprint, a second binning size is selected. Fingerprintinformation of the user fingerprint may be obtained again based on use of the fingerprint recognition sensor driven by a pixel binning scheme based on the second binning size. 描述了用于基于光学指纹辨识来注册指纹的系统和方法。显示指纹辨识窗口，并且使用通过基于第一合并大小的像素合并方案驱动的指纹辨识传感器，基于通过指纹辨识窗口接收到的反射的光来分析用户指纹的指纹频率。可以基于指纹频率来评估第一合并大小。如果第一合并大小不适合于注册用户指纹，则选择第二合并大小。可以基于使用通过基于第二合并大小的像素合并方案驱动的指纹辨识传感器，再次获得用户指纹的指纹信息。
