SYNCHRONIZATION DEVICE, SYNCHRONIZATION METHOD, AND NON-TRANSITORY TANGIBLE COMPUTER READABLE STORAGE MEDIUM

A synchronization device is for a vehicle equipped with a plurality of sensors including an image sensor. The synchronization device acquires, as data related to a motion state of the vehicle, first time-series data based on detection data detected by the image sensor and second time-series data based on detection data detected by a sensor other than the image sensor. The synchronization device calculates shift time required for matching the first time-series data with the second time-series data.
