To provide a biometric measurement device capable of easily detecting a pulse wave of a subject, etc., and also preventing an action of a subject from being disturbed when detecting a pulse wave, etc.SOLUTION: The face of a subject is irradiated with a near infrared ray from a light emitting element. A pulse wave of a subject is acquired from an image of the face of a subject imaged at this time by a camera. Then, a state of a subject is determined based on the pulse wave. Besides, a pulse wave analysis part is identified from an image of the face of a subject imaged by a camera with a near infrared ray by the light emitting element. The pulse wave analysis part is irradiated with a near infrared ray at different timing from a different light emitting element with higher luminous intensity compared with the former light emitting element, so as to acquire a pulse wave of a subject from an image of the pulse wave analysis part. Then, a state of a subject is determined based on the pulse wave.SELECTED DRAWING: Figure 1
【課題】簡単に被験者の脈波等を検出できるとともに、脈波等を検出する際、被験者の動作を妨げることがない生体測定装置を提供する。【解決手段】発光素子から被験者の顔面に近赤外光を照射し、このときにカメラで撮影された被験者の顔面の画像から被験者の脈波を取得し、この脈波に基づいて被験者の状態を判定する。また、発光素子による近赤外光によりカメラで撮影された被験者の顔面の画像から脈波解析箇所を特定し、この発光素子より光度が高い別の発光素子を異なるタイミングでその脈波解析箇所に近赤外光を照射させることにより、脈波解析箇所の画像から被験者の脈波を取得し、この脈波に基づいて被験者の状態を判定する。【選択図】図1
