摘要
An offset correction apparatus for a gyro sensor includes an acceleration sensor, a geomagnetic sensor, a stationary determination unit that determines, by using an output value of the acceleration sensor and an output value of the geomagnetic sensor, whether the gyro sensor is stationary, a difference calculation unit that calculates an offset value of the gyro sensor by using an output value of the gyro sensor, and an offset-value update unit that assumes, as a new offset value, an offset value calculated by the difference calculation unit by using an output value of the gyro sensor determined to be stationary by the stationary determination unit.
