Hereinafter, application examples will be enumerated, but the description of each operation can be easily inferred from each of the above-described embodiments, and thus description thereof will be omitted.
[0076]
(1) Vehicle accident certification system
Using the video information providing system described above, for example, the storage of video information in the large-capacity storage device is stopped after several tens of seconds immediately after the information-providing vehicle is involved in an accident, and the stored contents of the large-capacity storage device are reproduced. To help with accident proof. Therefore, even if the information providing vehicle is involved in an accident, the reproduced video information makes it easy to prove the responsibility for the harm and can be used for negotiation with the perpetrator.
[0077]
(2) Crime prevention system
For example, when a crime involving an information providing vehicle occurs using the video information providing system described above, the stored contents of the large-capacity storage device are reproduced to help identify the crime. Therefore, even if a crime is committed in a car such as a taxi or a bus, the crime information can be easily identified by storing video information with time information, position information, and speed information.
[0078]
(3) Road management system
Using the above-described video information providing system, for example, a road condition during traveling is photographed by an imaging means (video camera that images the front) of an information providing vehicle, and this is stored as video information in a mass storage device and used. When there is a complaint or inquiry about a road from a person, the stored contents of the large-capacity storage device are reproduced to help prove the road management state. Therefore, even if a complaint or inquiry about a road is received from a user, it can be easily handled.
[0079]
(4) Trouble proof system
Using the video information providing system described above, for example, it is possible to reproduce the stored contents of the large-capacity storage device for troubles occurring during the rental of the information providing vehicle and prove whether there is a defect on the lessee side or the lessor side. It can be so. Therefore, when returning a rental car, it is possible to easily prove it by using the video information that reproduces whether it is a borrower's trap or a lender's trap, which brings benefits to both.
