Abstract
The invention relates to a portable electronic device having correctable azimuths and a correction method thereof. When the portable electronic device is operated in different use modes, one or more sensors therein have relative state parameters. When the portable electronic device is in a first use mode, an electronic compass therein loads a relatively preset first setting value according to a senor state parameter corresponding to the first use mode to carry out geomagnetic detection and output data of azimuths. When the portable electronic device changes from the first use mode into a second one, the electronic compass suspends the geomagnetic detection temporarily and loads a relatively preset second setting value according to a senor state parameter corresponding to the changed second use mode to continue the geomagnetic detection and output data of azimuths. The normal geomagnetic detection is continued through loading different preset setting values to rapidly deal with different statuses of disturbing magnetic field.
