Data synchronization device, data synchronization method and data synchronization program

摘要

In this data synchronization device (20), a first estimation unit (510) estimates, from among moving image data (33), a data range at the time when a vehicle turns right or left as a first data range. A second estimation unit (52) estimates, from among acceleration data (34), a data range at the time when the vehicle turns right or left as a second range. A synchronization unit (53) performs time synchronization between the moving image data (33) and the acceleration data (34) on the basis of a time range corresponding to the first data range estimated by the first estimation unit (51) and a time range corresponding to the second data range estimated by the second estimation unit (52).
