Abstract
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.
Claims15
A correction method of a geomagnetic sensor in a mobile device, characterized by comprising:
- a step in which, in a mobile device having 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, the position detection means detects a predetermined position change;
- and
- a step in which the controller starts a correction process of the geomagnetic sensor based upon the detection.
A mobile device comprising:
- 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,
- wherein the controller starts a correction process of the geomagnetic sensor when the position detection means detects a predetermined position change.
A program executable in a controller of a mobile device having a geomagnetic sensor, position detection means for detecting a position of the mobile device, and the controller operable to control the geomagnetic sensor and the position detection means, characterized by allowing the controller to perform:
- a procedure of detecting a predetermined position change by the position detection means;
- and
- a procedure of starting a correction process of the geomagnetic sensor based upon the detection.
