Abstract: A first converter converts an initial attitude in an Euler angle representation into an initial attitude represented by quaternion. An updating unit updates an attitude represented by quaternion by defining the initial attitude represented by quaternion as an initial value, successively substituting output values of the triaxial gyro sensor. A second converter converts the attitude represented by quaternion into an attitude in the Euler angle representation. An angular speed derivation unit derives an angular speed based on a time-dependent change in the attitude in the Euler angle representation. A controller adjusts a period of time for derivation by an initial attitude derivation unit based on a variance value of the output value of the triaxial acceleration sensor or a variance value of the output value of the triaxial gyro sensor, when the speed is lower than a threshold value.
