PROBLEM TO BE SOLVED: To provide an activity meter that can accurately estimate the amount of activity according to a behavior mode of a subject to be measured of the amount of activity.SOLUTION: There is provided the activity meter 1 for measuring the amount of activity of a human body based on a detection result of acceleration of an acceleration sensor 11. The activity meter determines the behavior mode of the human body and measures the amount of activity according to the determined behavior mode based on standard deviation of the acceleration obtained by the detection result of the acceleration and the number of steps per predetermined time.COPYRIGHT: (C)2012,JPO&INPIT【課題】活動量の計測対象者の行動態様に応じて、活動量を精度良く推定することのできる活動量計を提供する。【解決手段】加速度センサ11による加速度の検出結果に基づいて人体の活動量を計測する活動量計1は、加速度の検出結果から得られる加速度の標準偏差と所定時間当たりの歩数とに基づいて人体の行動態様を判定するとともに、判定した行動態様に応じて活動量を計測する。【選択図】図2
