Classification: CPC A | IPC A

Claim 14:
15. A biosignal processing apparatus comprising:
at least one processor configured to:
remove a direct current (DC) component from a biosignal;
extract reference points from a waveform of the biosignal from which the DC component is removed, the reference points comprising a first reference point having a highest signal value from among neighboring first candidate reference points and a second reference point having a lowest signal value from among neighboring second candidate reference points;
determine pulse sharpness levels corresponding to each of the first reference points and the second reference point;
determine feature points of the biosignal based on the pulse sharpness levels; and
transfer, to a bioinformation estimating apparatus, the feature points such that bioinformation of a user is estimated based on the feature points,

wherein one or more of the pulse sharpness levels corresponds to an angle formed between a first line connecting a first reference point to a neighboring reference point and a second line connecting the first reference point to another neighboring reference point.
