1. A pulse wave processing apparatus comprising:
- an obtaining unit that obtains pulse wave signal data expressing a pulse wave of a subject and body movement signal data expressing body movements of the subject;
a correlation coefficient calculating unit that calculates a correlation coefficient expressing a degree of correlation between the pulse wave signal data and the body movement signal data; and
a pulse wave eliminating unit that eliminates one or more pieces of the pulse wave signal data in which the correlation coefficient is equal to or larger than a predetermined threshold value.

Abstract
Pulse wave signal data expressing the pulse wave of a subject and body movement signal data expressing body movements of the subject are obtained so that a correlation coefficient expressing the degree of correlation between the pulse wave signal data and the body movement signal data is calculated. One or more pieces of the pulse wave signal data in which the correlation coefficient is equal to or larger than a predetermined threshold value are eliminated.
