The information processing apparatus (100) acquires data indicating the time when the monitoring target has detected that the monitoring target has taken a predetermined posture, based on the output value from the sensor corresponding to the monitoring target. The information processing apparatus (100) refers to the storage unit (110) and determines whether or not the time indicated by the acquired data is included in a time zone in which a predetermined posture is taken. The information processing apparatus (100) detects an abnormality of a monitoring target when the time indicated by the acquired data is not included in a time zone in which the data takes a predetermined posture. On the other hand, the information processing apparatus (100) does not detect an abnormality of the monitoring target when the time indicated by the acquired data is included in a time zone in which the data takes a predetermined posture.情報処理装置(100)は、監視対象に対応するセンサからの出力値により監視対象が所定の姿勢をとったことを検知した際の時刻を示すデータを取得する。情報処理装置(100)は、記憶部(110)を参照して、取得したデータが示す時刻が、所定の姿勢をとる時間帯に含まれるか否かを判断する。情報処理装置(100)は、取得したデータが示す時刻が、所定の姿勢をとる時間帯に含まれない場合に、監視対象の異常を検出する。一方、情報処理装置(100)は、取得したデータが示す時刻が、所定の姿勢をとる時間帯に含まれる場合には、監視対象の異常を検出しない。
