Here, for example, when the route information image 40 of a predetermined size centered on the position in the specified route information image 40 is not stored in the route information image storage unit 72, the route information image 40 is insufficient. It may be determined. Then, when it is determined that the route information image 40 is insufficient, the request transmission unit 88 may transmit the transmission request of the route information image 40 of the insufficient portion to the route information providing server 10.

Then, in response to the reception of the transmission request of the route information image 40 of the insufficient portion by the request receiving unit 56, the route information image transmitting unit 60 may transmit the requested route information image 40 of the insufficient portion to the terminal 12. .. Then, the route information image receiving unit 92 of the terminal 12 may receive the route information image 40 of the insufficient portion, and the route information image 40 of the received insufficient portion may be stored in the route information image storage unit 72. Here, the route information image 40 of an unnecessary portion stored in the route information image storage unit 72 may be overwritten.

Further, for example, when the reception unit 78 accepts the download operation, the request transmission unit 88 transmits a transmission request for the shooting moving image and the route information image 40 having a size corresponding to the cache capacity of the terminal 12 to the route information providing server 10. You may.

Then, in response to the reception of the request for transmission of the captured moving image of the size corresponding to the cache capacity of the terminal 12 by the request receiving unit 56, the moving image transmitting unit 58 transmits the captured moving image of the requested size to the terminal 12. You may. Then, the moving image receiving unit 94 of the terminal 12 may receive the shooting moving image of the size and store the shooting moving image of the received size in the moving image storage unit 70. Here, the photographed moving image of an unnecessary portion stored in the moving image storage unit 70 may be overwritten.

Further, in response to the reception of the transmission request of the route information image 40 having a size corresponding to the cache capacity of the terminal 12 by the request receiving unit 56, the route information image transmitting unit 60 transmits the route information image 40 of the requested size to the terminal 12. May be sent to. Then, the route information image receiving unit 92 of the terminal 12 may receive the route information image 40 of the size and store the route information image 40 of the received size in the route information image storage unit 72. Here, the route information image 40 of an unnecessary portion stored in the route information image storage unit 72 may be overwritten.

Hereinafter, an example of the flow of processing repeatedly performed at a predetermined frame rate on the route information providing server 10 according to the present embodiment will be described with reference to the flow diagram illustrated in FIG.
