Abstract

An increase in power consumption involved in calibration for calibrating an offset of a geomagnetism sensor is suppressed. An electronic device performs calibration of an output error of the geomagnetism sensor so that the geomagnetism sensor can output more accurate geomagnetism data based on angular speed data output by a gyro sensor. The electronic device controls turning ON/OFF of the gyro sensor. The electronic device determines whether or not calibration of the geomagnetism sensor is necessary. When it is determined that calibration of the geomagnetism sensor is unnecessary, the electronic device performs a control operation to turn OFF the gyro sensor.
