脈拍数推定方法、装置およびシステム
Document Type and Number:
Japanese Patent JP7282897
Kind Code:
B2
Abstract:
Provided is a method for estimating a pulse rate with high accuracy in the case that short-term burst noise is mixed in an estimation interval. Included are a pulse wave signal generating step of generating a pulse wave signal from an image of a pulse rate estimation target; a peak component suppression step of limiting an amplitude value of the pulse wave signal that is larger than a first threshold value to the first threshold value, and outputting a pulse wave analysis signal; and a frequency analysis step of outputting a frequency spectrum of the pulse wave analysis signal.
