PROBLEM TO BE SOLVED: To perform a correction process of a geomagnetic sensor with sufficient frequency while suppressing influence on operability.SOLUTION: A mobile device has a geomagnetic sensor, position detection means for detecting a position of the mobile device, and a controller 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 in response to the detection. |
