Abstract
An electronic watch includes a display surface, a magnetic sensor including a first detection axis and a second detection axis orthogonal to the first detection axis, with the first detection axis and the second detection axis being disposed in a plane parallel to the display surface, a correction unit configured to correct an error due to an offset magnetic field included in a detection value of the magnetic sensor, a calculation unit configured to calculate a bearing and magnetic intensity, based on a value acquired by correcting the detection value by the correction unit, and a display unit configured to cause the display surface to display the bearing and the magnetic intensity that are calculated by the calculation unit to be displayed.
Claims5
An electronic watch, comprising:
- a display surface;
- a magnetic sensor including a first detection axis and a second detection axis orthogonal to the first detection axis, the first detection axis and the second detection axis being disposed in a plane parallel to the display surface;
- and
- a CPU configured to
- correct an error, due to an offset magnetic field, included in a detection value of the magnetic sensor,
- calculate a bearing and magnetic intensity, based on a value acquired by correcting the detection value, and
- cause the display surface to display the calculated bearing and the calculated magnetic intensity.
The electronic watch according to claim 11, wherein
- the display surface includes a first pointer configured to indicate the bearing and a second pointer configured to indicate the magnetic intensity, and
- the CPU causes the first pointer and the second pointer to indicate the calculated bearing and the calculated magnetic intensity, respectively.
