| 摘要 | In order to be able to accurately measure pitch both during running and walking, the invention focuses on the fact that the second harmonic of the body movement can be detected at a high level during running and that the third harmonic of the body movement can be detected at a high level during walking, and is designed to be able to calculate pitch regardless of whether or not the user is running or walking, by using a high-level line spectrum appearing in the area that is at or above 100 times/minute, for example, as the reference wave, and by determining whether this reference wave is the second or third harmonic. Whether the reference wave is the second or third harmonic can be determined based on whether or not a high-level signal is present near a frequency that is 1/3 or 2/3 of the frequency of the reference wave, for example; and pitch can be calculated by determining that the reference wave is the second harmonic if no high-level signal is present in the above frequency band. | ||||||
