Classification: CPC A | IPC A

Claim 0:
1. A biosignal processing apparatus comprising:
at least one processor configured to:
extract reference points from a waveform of a biosignal, 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 point 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 the first reference point to a first candidate reference point from among the neighboring first candidate reference points and a second line connecting the first reference point to another first candidate reference point from among the neighboring first candidate reference points.
