METHOD FOR CORRECTING A GEOMAGNETIC SENSOR FOR A MOBILE DEVICE, AS WELL AS A MOBILE DEVICE AND A PROGRAM

A mobile device has a geomagnetic sensor, position detection means for detecting a position of the mobile device, and a controller operable to control the geomagnetic sensor and the position detection means. When the position detection means detects a predetermined position change, the controller starts a correction process of the geomagnetic sensor based upon the detection.
