Abstract
A biological information processing apparatus obtains a pulse wave signal indicating a pulse wave of a subject, and acceleration measured according to body motion of the subject and calculates an amount of body motion of the subject using the acceleration. By using at least one of the body motion amount and the acceleration, the apparatus approximates a heart rate of the subject and sets a parameter to be used for detection of a pulse interval using the heart rate. Then, the apparatus detects each pulse interval using a pulse waveform indicated by the pulse wave signal and the parameter.
