Abstract: 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.

Abstract: An imaging device includes a light source operating in response to an optical control signal having a predetermined frequency, a sensor including a plurality of pixels, configured to generate an electrical signal in response to a light reception signal output by the light source and reflected from a subject, and a logic circuit configured to generate first raw data of a spatial domain based on the electrical signal, and an image signal processor configured to convert the first raw data into second raw data of a frequency domain, to select low-frequency data of the second raw data within a frequency band lower than a predetermined reference frequency, to apply a predetermined weighting to the low-frequency data to generate weighted data, and to generate a resultant image based on the first raw data and the weighted data.
