Location calculating method and location calculating device

A location calculating device comprising:

• a first process performing unit that acquires measurement information by receiving satellite signals from positioning satellites and stores the acquired measurement information in a storage unit in association with acquisition time;
• a second process performing unit that calculates movement information that includes a movement direction and a movement distance by using a detection result of a sensor unit that at least includes an acceleration sensor and stores the calculated movement information in the storage unit in association with calculation time;
• and
• a location calculating unit that calculates a past location corresponding to a desired time in the past when a photographing process was performed by using at least the measurement information of which the acquisition time satisfies a predetermined proximity time condition and the movement information of which the calculation time is between the acquisition time of the measurement information and the given desired time.
