Abstract
An electronic device includes a magnetic sensor which detects a magnetic field around the electronic device and outputs magnetic data in accordance with the magnetic field detected by the magnetic sensor, a position acquiring section which acquires position information regarding a geographic position of the electronic device, and a processing unit. The processing unit acquires, from the position acquiring section, specific position information for a specific position of the electronic device when an output vector of the magnetic data is oriented to a magnetic pole direction of the earth, derives a geomagnetic vector at the specific position based on the specific position information, and acquires an offset value based on a comparison between the geomagnetic vector and the output vector.
