ABSTRACT:
To carry out step number measurement more precisely even when a walk signal enough to be detected is not obtained. After a fixed noise of a signal detected by an acceleration detecting portion having an acceleration sensor is removed by a filter portion of a counting portion, a walk cycle comparing portion compares a cycle of the resultant signal with a moving average value calculated by a walk cycle calculating portion, and each signal within a predetermined cycle range is counted as the number of steps for one step by a step number counting portion. A signal within a range similar to a cycle n times as large as a predetermined cycle of the signals each beyond the predetermined cycle range is judged as the number of steps for n steps by an extra-regulation step number processing portion and is counted as the number of steps for n steps by the step number counting portion. Data on the number of steps obtained through the counting in the step number counting portion is displayed on a display portion.
