PROBLEM TO BE SOLVED: To improve detection accuracy of a heartbeat signal by a heartbeat sensor.SOLUTION: A heart rate is estimated based on a detection signal of an inertial sensor 22, and a timing for controlling a frequency band to be processed in a detection signal of a heartbeat sensor 21 according to the estimated heart rate is delayed with respect to the heart rate estimation timing.SELECTED DRAWING: Figure 8【課題】心拍センサによる心拍信号の検出精度を向上する。【解決手段】慣性センサ２２の検出信号を基に心拍数を推定し、推定した心拍数に応じて心拍センサ２１の検出信号において処理する周波数帯を制御するタイミングを、前記心拍数の推定タイミングに対して遅延させる。【選択図】図８
