Zusammenfassung:	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. Fingerprint information of the user fingerprint may be obtained again based on using the fingerprint recognition sensor driven by a pixel binning scheme based on the second binning size.
