A second n-fold angle signal is calculated using a first sine wave signal and a second sine wave signal obtained from a first n-fold angle signal that is an angle signal multiplied by n (n is a real number other than 1), offset correction values of the first sine wave signal and the second sine wave signal respectively are calculated from the second n-fold angle signal, the first sine wave signal is corrected by the calculated offset correction value of the first sine wave signal being added to the first n-fold angle signal, and the second n-fold angle signal is corrected by the calculated offset correction value of the second sine wave signal being added to the second sine wave signal.
