PROBLEM TO BE SOLVED: To measure electrocardiographic waveform signals without making a subject conscious of the measurement.SOLUTION: The measurement apparatus includes: a plurality of transparent electrodes provided on a surface of a display an acquisition part for acquiring an imaging signal by imaging the surface of the display from the inner side of the display a setting part for setting electrode pair candidates from the plurality of transparent electrodes based on the imaging signal acquired with the subject touching the surface of the display an electrocardiographic waveform signal measurement part for measuring electrocardiographic waveform signals of the subject using the respective set electrode pair candidates and a determination part for determining an electrode pair for measurement among the electrode pair candidates based on the electrocardiographic waveform signals measured by using the respective electrode pair candidates. The measurement apparatus is applicable to, for example, a personal authentication process of the subject based on the electrocardiographic waveform signals.COPYRIGHT: (C)2013,JPO&INPIT【課題】被測定者に意識させることなく心電波形信号を測定する。【解決手段】本開示の測定装置は、ディスプレイの表面に設けられた複数の透明電極と、前記ディスプレイの前記表面を前記ディスプレイの内側から撮像した撮像信号を取得する取得部と、被測定者が前記ディスプレイの前記表面に接触している状態で取得された前記撮像信号に基づいて、前記複数の透明電極の中から電極対候補を設定する設定部と、設定された各電極対候補を用いて前記被測定者の心電波形信号を測定する心電波形信号測定部と、各電極対候補を用いて測定された前記心電波形信号に基づき、電極対候補の中から測定用電極対を決定する決定部とを備える。この測定装置は、例えば、心電波形信号に基づいて被測定者の個人認証処理を行う場合に適用できる。【選択図】図7
