PROBLEM TO BE SOLVED: To provide a moving distance calculator capable of calculating precisely a moving distance of a vehicle. SOLUTION: A moving speed based on an acceleration data detected by an acceleration sensor 12 is brought into zero, based on stop determination by an imaging part 13. An off-set value is calculated based on the acceleration data stored sequentially in a storage part 14 during a stop determination period, to calibrate the acceleration sensor 12.
