Title:
PULSE RATE DETECTION DEVICE, EXERCISE DEVICE, AND PULSE RATE DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/107149
Kind Code:
A1
Abstract:
The purpose of the present invention is to correctly measure a pulse rate when a subject is moving. A pulse rate detection device 1 uses a camera 8 to image a face of a subject 11 that is performing aerobic exercise using an exercise device, detects the pulse rate of the subject 11 from a change in a color component of the skin, and displays the detected pulse rate on a display unit 5. The pulse rate of the subject 11 is detected according to a pulse rate peak in a frequency region of a pulse rate signal based on the change in the color component of the skin. If the pulse rate peak and a movement peak are separated from each other, the pulse rate detection device 1 analyzes these peaks to detect the pulse rate from the pulse rate peak. If the pulse rate peak and the movement peak overlap, the pulse rate detection device 1 detects the pulse rate using the fact that these peaks overlap. Thus, the pulse rate detection device 1 performs appropriate processing by monitoring the pulse rate signal and the movement disturbance signal during the period in which the subject 11 is exercising. As a result, the pulse rate detection device 1 can measure and submit in real time the pulse rate of the subject 11 while exercising.
