Claim:
1. A movement amount estimation system, comprising a storage area configured to store acceleration data including a time of measurement by an acceleration sensor which a mobile terminal has and an acceleration measured by the acceleration sensor, for estimating a movement amount of a holder of the mobile terminal based on the acceleration sensor data, the movement amount estimation system further comprising: an elevator riding time period detection part configured to detect a start time and an end time of an elevator riding time period of the holder based on an increase and decrease of the acceleration data stored in the storage area; a movement velocity calculation part configured to integrate the acceleration data from the start time to the end time by a time period from the start time to the end time to calculate a movement velocity of the holder from the start time to the end time; a movement velocity correction part configured to correct one of a movement velocity at the start time and a movement velocity at the end time based on another of the movement velocity at the start time and the movement velocity at the end time; and a movement amount estimation part configured to integrate the movement velocity corrected by the movement velocity correction part by the time period from the start time to the end time to estimate a movement amount of the holder when the holder uses an elevator.
