Abstract:
1. A pedometer comprising: a sensor that detects a moving motion of a person and that outputs a detecting signal in correspondence therewith; a filter to which is inputted the detecting signal from the sensor and which has a variable passing frequency band; filter controlling means for switching the passing frequency band of the filter to either of a band for walking and a band for running; step number calculating means for calculating a number of steps based on the detecting signal passing through the filter; signal level determining means for determining a level of the detecting signal passing through the filter; and moving motion determining means for determining that the moving motion is changed from walking to running when the signal level determining means determines that a signal level of the detecting signal is at a predetermined level or higher and a period of the detecting signal from the filter set to the band for running is at a period within a predetermined range; wherein when the moving motion determining means determines running, the filter controlling means maintains the passing frequency band of the filter to a state of setting the band for running, and the step number calculating means calculates the number of steps based on the detecting signal passing the filter.
