PROBLEM TO BE SOLVED: To provide a biological information acquisition device capable of acquiring accurate biological information by avoiding the influence of temperature independence of a biogenic substance without separately providing temperature measurement means.SOLUTION: A biological information acquisition device 1 includes a light source for irradiating light to a living body F, a photodetector for receiving light from the living body, and a calculation part 74, 76 for calculating biological information on the basis of a detection result of the photodetector. The calculation part 74, 76 detects a detection value during light emission with the photodetector when the light source emits light, detects a detection value at extinction with the photodetector when the light source stops light emission, acquires a temperature dependent component of the detection value during light emission on the basis of the detection value at extinction, and corrects the detection value during light emission.COPYRIGHT: (C)2016,JPO&INPIT【課題】温度測定手段を別個に設けることなく、生体成分の温度依存性の影響を回避して正確な生体情報を取得できる生体情報取得装置を提案する。【解決手段】生体情報取得装置1は、生体Fに光を照射する光源と、生体からの光を受光する受光素子と、受光素子の検出結果に基づいて生体情報を求める演算部74,76と、を備える。演算部74,76は、光源が発光したときに、受光素子で発光時検出値を検出し、光源が消光したときに、受光素子で消光時検出値を検出し、消光時検出値に基づいて発光時検出値の温度依存成分を求めて、発光時検出値を補正する。【選択図】図1
