PROBLEM TO BE SOLVED: To detect an inflection point of a biological signal with high accuracy in comparison to a case of directly detecting an inflection point from a biological signal.SOLUTION: A biological information measurement apparatus 10 comprises: a generation unit 50 which generates an intermediate signal obtained by removing at least part of information on an inflection point other than an inflection point to be detected, from a biological signal in which an inflection point of a person to be measured appears periodically; an identifying unit 52 for identifying the position of an inflection point of the intermediate signal corresponding to the inflection point to be detected; and a detecting unit 54 for detecting the position of the inflection point to be detected in the biological signal on the basis of the position of the inflection point of the intermediate signal.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2020,JPO&INPIT【課題】生体信号から直接変曲点を検出する場合と比較して、精度良く生体信号の変曲点を検出することができる。【解決手段】生体情報測定装置10は、被測定者の周期的に変曲点が現れる生体信号から、検出対象の変曲点以外の変曲点の情報を少なくとも一部除去した中間信号を生成する生成部50と、検出対象の変曲点に対応する中間信号の変曲点の位置を特定する特定部52と、中間信号の変曲点の位置に基づいて生体信号における検出対象の変曲点の位置を検出する検出部54と、を備える。【選択図】図7
