PROBLEM TO BE SOLVED: To provide a technique for accurately acquiring biological information.SOLUTION: A biological information acquisition device acquires N sets of one set of light-receiving results constituted by a first light-receiving result and a second light-receiving result by selecting N pairs (N is an integer of 2 or more) of light-receiving sections for measurement and light-receiving sections for reference and executing light-receiving processing for selecting light-receiving sections separated from a light-emitting section for measurement by second distances as the light-receiving sections for reference and acquiring the second light-receiving result while selecting the light-receiving sections separated from the light-emitting section for measurement by the second distances greater than first distances as light-receiving sections for measurement out of a plurality of light-receiving sections receiving light irradiated from the light-emitting section for measurement and acquiring the first light-receiving result, and acquires biological information by using the N sets of light-receiving results.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2018,JPO&INPIT【課題】生体情報を精度良く取得する技術を提供する。【解決手段】生体情報取得装置は、測定用発光部から照射された光を、複数の受光部のうち、測定用発光部から第1の距離よりも大きな第2の距離だけ離れた受光部を測定用受光部として選択して第1の受光結果を取得するとともに、測定用発光部から第2の距離だけ離れた受光部をリファレンス用受光部として選択して第2の受光結果を取得する受光処理を、N対(Nは2以上の整数)の測定用受光部及びリファレンス用受光部を選択して実行することによって、第1の受光結果及び第2の受光結果で構成される一組の受光結果をN組取得し、N組の受光結果を用いて、生体情報を取得する。【選択図】図13
