Title:
HEARTBEAT DETECTION DEVICE, HEARTBEAT DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/003910
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the accuracy of detection of heart rate, and to reduce the time for detection of heart rate. A heartbeat detection device 1 is provided with a heartbeat detection unit 16 for detecting the heart rate using the luminance of captured images of a part of the body surface of a user that have been captured in a plurality of frames in chronological order. The heartbeat detection unit 16 computes a total of the luminance of the captured images of the frames, delays, by certain time intervals, a vibrating wave representing the chronological change in the total luminance, and computes the heart rate from the period of a peak at which, in a waveform of the difference between the vibrating wave before the delay and each vibrating wave after the delay, the difference is reduced.
