A bio-processor, a bio-signal detecting system, and an operation method of the bio-processor are provided. The bio-processor includes a bioelectrical impedance sensor and a digital signal processor. The bioelectrical impedance sensor measures bioelectrical impedance during a sensing time including a portion of a settling time. The digital signal processor estimates a settled bioelectrical impedance value based on changes in the measured bioelectrical impedance. The digital signal processor generates bio-data based on the settled bioelectrical impedance value. The bio-processor reduces a time when a bio-signal is measured and ensures accuracy of the settled bioelectrical impedance value.

Provided is a photoplethysmogram (PPG) sensing module including one or more light sources that emit light to a user; a plurality of optical sensors that receive reflected light from the user and generate sensing signals, each of the sensing signals being generated by one of the optical sensors; a read-out signal generating circuit that receives the sensing signals from the optical sensors and generate read-out signals by performing an analog-to-digital conversion on the sensing signals; and a signal processing circuit that receives the read-out signals, classifies the read-out signals according to one or more movement patterns of the user, measures a movement component of the user based on the classified read-out signals, and generates a PPG signal in which the movement component is removed.

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.
