PORTABLE ELECTRONIC DEVICE AND METHOD OF CONTROLLING THE SAME

摘要

A portable electronic device (100) having an earth magnetism sensor (110) for detecting earth magnetism used to calculate a direction, a calibration data acquisition section (121) for acquiring calibration data for correction in the direction calculation, a direction calculation section (125) for calculating a direction by using earth magnetism and the calibration data, and a control section (124, 120) for preventing, when calibration data is acquired by the calibration data acquisition section when at least one function among plural functions is being executed, this calibration data from being used for direction calculation by the direction calculation section.
