Therefore, the information processing device 20 can confirm that the state corresponding to the above change has been resolved. When it is confirmed that the state corresponding to the above change has been resolved, the information processing device 20 can discard the image having the change from the past image without holding it.

Further, in the information processing apparatus 20, the information indicating the above change may include information indicating the urgency of resolving the state corresponding to the change.

Therefore, on the management server 30 side, it is possible to respond according to the urgency.

Further, in the information processing apparatus 20, the acquisition unit 20a can periodically acquire video and shooting information from the drive recorder 10.

Therefore, the information processing apparatus 20 can promptly and continuously confirm changes in the road and the vicinity of the road by periodically acquiring the video and the photographed information.

Further, in the information processing apparatus 20, the information indicating the above change may include information indicating the weather at the time of shooting the image.
