1. A data processing apparatus comprising:
processing circuitry:
to acquire as a first movement amount, an estimated movement amount of a moving body calculated using photographed image data acquired by a photographic device installed on the moving body, said photographic device corresponding to a first type of imaging;
to acquire in synchronization with the acquisition of the first movement amount, as a second movement amount, an estimated movement amount of the moving body with higher estimation accuracy than estimation accuracy of the first movement amount; and
to compare the first movement amount with the second movement amount, and decide to use the first movement amount for a calibration operation associated with a coordinate system of a second type of imaging when a difference between the first movement amount and the second movement amount is less than a threshold value.
