Mobile Electronic Apparatus and Bearing Display Method of Same
First Claim
1. A mobile electronic apparatus comprising:
- a display part displaying information;
a geomagnetic sensor detecting geomagnetism; and
a control part configured to calculate a bearing based on geomagnetism detected by the geomagnetic sensor and to display the information of the calculated bearing on the display part, wherein,when an external device generating a magnetic field is connected to the electronic apparatus in a state where the information of the bearing is displayed on the display part, the control part displays that the information of the bearing is incorrect on the display part, or the control part stops the display of the information of the bearing.

Abstract
A mobile electronic apparatus capable of effectively preventing erroneous recognition of a bearing (azimuth or compass direction) by a user, as a correct display of the bearing is correct when the reliability of the display of the bearing is lowered by a change of the usage environment, and a bearing display method of the same, are provided.
If a mobile electronic apparatus (100) is mounted on a charger (200) having a speaker (201), while information on a bearing calculated according to geomagnetism detected by a geomagnetic sensor (108) is displayed on a display part (107), updating of the information on the bearing repeated up to them is stopped, and information on a predetermined bearing is continuously displayed on the display part (107). This enables a user to correctly recognize that the information on the bearing displayed on the display part (107) is incorrect, thereby preventing the user from being misled by the unreliable information on the display part (107).
