Provided is a mobile device including a magnetic sensor and a posture detection sensor for detecting a posture of the mobile device independently of the magnetic sensor, which acquires output data of the magnetic sensor as a plurality of sampling data items in a plurality of states in which the posture detection sensor determines that the mobile device is directed in directions different from one another, the plurality of sampling data items respectively corresponding to the plurality of states, and calculates an offset value which is estimated to be output by the magnetic sensor when the magnetic sensor is not sensing geomagnetism based on the acquired plurality of sampling data items.
