PULSE WAVE DETECTION DEVICE, APPARATUS CONTROL DEVICE, AND PULSE WAVE DETECTION METHOD |
摘要 |
<p>A pulse wave detection device for detecting pulse wave data indicating a pulse wave of a user, the pulse wave detection device including: a pulse wave detection unit (1011) configured to detect, in time series, the pulse wave data indicating the pulse wave of the user; a pulse wave derivative unit (1012) configured to calculate time-series velocity plethysmogram data by temporally deriving the time-series pulse wave data detected by the pulse wave detection unit (1011); a component extraction unit (1013) configured to extract a maximum value and a minimum value in a current first time range in the time-series velocity plethysmogram data calculated by the pulse wave derivative unit (1012) while shifting the current first time range in a time axis direction, the extraction being repeated in a next current first time range; a component ratio calculation unit (1014) configured to calculate a component ratio which is a ratio of the maximum value and the minimum value extracted for each current first time range by the component extraction unit (1013); and a noise segment determination unit configured to determine, as a noise segment, a segment in which component ratios calculated by the component ratio calculation unit are temporally inconstant.</p> |
