The invention provides a pedometer and a program. whenever an output signal of an acceleration transducer is detected to a reducing from an increasing(e.g. being a peak value), the peak value is compared with a first threshold value, and a time interval between the peak value and the detection timing of the previous peak value is compared with a second threshold value to judge whether to count the step number, and then, the detected peak value is compared with a third threshold value greater than the first threshold value, and a time interval between the peak value and the previous peak value is compared with a fourth threshold value representing a time shorter than the second threshold value to judge the action type of users(e.g. running, walking or other state). Under the situation of being judged as running or walking, the falling steep degree of a wave form after appearing a peak in an acceleration time waveform is estimated according to the judged result, and the step number is added up according to each action type.

The invention discloses a frequency measuring method and a frequency measuring system. The frequency measuring method includes: latching pulse edges of input signals by means of clock signals to acquire pulse number Np and clock number Nc in sampling time, and computing pulse frequency P according to P=(NpxC) / Nc, wherein relative error by the frequency measuring method is + / -1 / Nc. When in low frequency, the relative error + / -1 / Np corresponding to + / - pulse signals in existing frequency measuring method is converted into + / -1 / Nc equivalently, while the clock number Nc is much higher than the pulse number Np, namely + / -1 / Nc is much smaller than + / -1 / Np, and accordingly, accuracy is improved. When in high frequency, by setting reasonable unit timing time and being compared with existing period measuring method, the Nc is increased along with prolonging of periods of input signals in the unit timing time, while + / - / Nc is reduced, and accuracy is improved as well. Therefore, when in high frequency and low frequency, the frequency measuring method is higher in measuring accuracy as compared with the existing measuring method.
