BIOLOGICAL INFORMATION MEASURING APPARATUS, NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM HAVING STORED THEREIN A PROGRAM FOR CAUSING A COMPUTER TO EXECUTE A PROCESS FOR MEASURING BIOLOGICAL INFORMATION, AND METHOD FOR MEASURING BIOLOGICAL INFORMATION
A biological information measuring apparatus includes a distortion calculating unit that calculates, based on video pulse wave information representing a video pulse wave expressing a temporal change in a brightness value included in a video signal of a predetermined part of a subject, a waveform distortion obtained from a heartbeat basic component containing a frequency component of a heartbeat frequency band corresponding to a heart rate of the subject and a heartbeat high-frequency component related to a waveform of a pulse wave and containing a frequency component of a frequency band higher than the heartbeat frequency band, the heartbeat basic component and the heartbeat high-frequency component being included in the video pulse wave； and a measuring unit that measures a fluctuation in a blood pressure of the subject based on the waveform distortion calculated by the distortion calculating unit.
