PROBLEM TO BE SOLVED: To attain much more accurate body motion (number of step) display in a body motion detector for determining a plurality of body motions to be detected with prescribed intervals as continuity, counting body motions based on the continuous detection of body motions, and switching and displaying the number of body motions for every time when counting the body motions.SOLUTION: When the change of attitudes is detected by an attitude change detection part 44 during the continuous detection of body motions, the switching display of the number of body motions is stopped since the detection of the change of the attitude until the lapse of a prescribed time, and after the detection of the change of the attitude, the number of body motions detected in the prescribed time is counted, and after the lapse of the prescribed time, the counted number of body motions is added to the number of body motions whose display has been stopped for display. Thus, it is possible to prevent the count-up of the display of the number of steps corresponding to vibration other than walking after the change of the attribute.COPYRIGHT: (C)2009,JPO&INPIT【課題】所定間隔で検出される複数の体動を連続と判断し、前記体動の連続した検出に基づいて体動を計数し、体動を計数するごとに体動数を切り替えて表示する体動検出装置においてより的確な体動(歩数)表示をおこなうこと。【解決手段】体動の連続検出中に、姿勢変化検出部44によって姿勢の変化が検出された場合に、当該姿勢の変化が検出されてから所定時間が経過するまで体動数の切り替え表示を停止し、姿勢の変化が検出された後、前記所定時間の間に検出された体動数を計数し、当該所定時間の経過後に、計数された体動数を表示が停止されていた体動数に加算して表示するので、姿勢変化後の歩行以外の振動に対応した歩数表示のカウントアップを防止する。【選択図】図2
