<P>PROBLEM TO BE SOLVED: To provide a device capable of accurately computing the number of steps and reducing its configuration cost. <P>SOLUTION: The inclination direction of an accelerator sensor 100 is calculated by inclination deciding parts 4 to 6 on the basis of X, Y an Z components 1 to 3 from the acceleration sensor 100, and whether acceleration excluding the fluctuating components of the acceleration of the respective X, Y and Z components measured by the acceleration sensor 100 is positive or negative is decided. The fluctuating components of the X, Y and Z components 1 to 3 are inverted or non-inverted by inverting/non-inverting parts 7 to 9 on the basis of the decision result. The processed results are added by a three-axis adding part 10, and components necessary for calculating the number of steps are extracted by a number-of-steps valid component extracting part 11, and the number of steps is counted by a number-of-steps counting part 12, and the counted result is stored in a number-of steps storage part 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
