That is, a telephone network is connected to the center 112, and the mobile station 200 is connected via the telephone network. The connection between the mobile station 200 and the telephone line network is performed by mobile communication via a normal switching center or base station. Note that the base station and the mobile station 200 are connected by wireless communication. In addition, this communication is not limited to a method using a telephone line, but may employ various methods such as direct wireless communication, satellite communication, or the like.

On the other hand, the mobile station 200 is a vehicle-mounted device,
It has a telephone 210. The telephone 210 is a mobile telephone or an automobile telephone, and is connected to the fixed station 1 via a telephone line.
The video information is obtained from 00.

The telephone 210 is connected to the information communication ECU 212. The information communication ECU 212 converts the image data into image data received by the telephone 210. The information communication ECU 212 performs processing for transmitting and receiving various data using the telephone 210.

The information communication ECU 212 is a navigation ECU 21.
The video data obtained by the information communication ECU 212 is supplied to the navigation ECU 214. Navi EC
U214 performs normal route guidance, in which a GPS device 216 is connected as current position detecting means, and a map database 218 is connected as map information providing means. Further, a display 220 is connected to the navigation ECU 214 as a display unit for displaying various images.

Then, the navigation ECU 214 communicates with the information communication E
The video data supplied from the CU 212 is displayed on the display 2

Next, the procedure for obtaining and displaying the video information will be described with reference to FIG. First, when the driver or the like wants an image of a specific point (for example, point A), the telephone 210 is used to connect the line to the center 112. Then, an image of the point A is requested. Center 11
2 obtains and transmits an image from the camera 110 installed at the point A. As a result, the mobile station 200 obtains a road image of the point A via the telephone line using the telephone 210 (S11). Next, the direction of the obtained image of the point A (drawing angle) is compared with the traveling direction of the own vehicle. here,
The direction of the video at the point A is stored in the map database 218 and is known in advance. That is, the map database 218 stores data about the installation location including the direction of the camera 110, and when requesting the image of the point A, the navigation ECU 214 recognizes the direction of the image to be sent. doing.

On the other hand, even if the center 112 adds data on the direction of the video data indicating from which direction the video data was transmitted when transmitting the video data, the navigation ECU 214 recognizes the direction of the video from the received data. Good. That is, it is easy for the center 112 to recognize all the positions of the camera 110 under its control, and the mobile station 2
It is easy to add data about the drawing direction of this video, such as the header of the video data sent to 00. Also,
The mobile station 200 can easily recognize the drawing direction from this data.

On the other hand, the direction of the own vehicle is stored in the map database 2.
GPS device 216 in the map data obtained from
The navigation ECU 214 is originally recognized from the movement of the current position obtained from. If the mobile station 200 has an azimuth sensor or the like, this data may be referred to.

Then, from the comparison result in S12, it is determined whether the direction of the image is the same as the direction of the own vehicle (S13). This determination is made, for example, as to whether the image is in the direction seen from the own vehicle, the image that can be seen when traveling in the lane, or if the image is viewed from above, the traveling direction is positioned upward. It is determined based on whether If the result of this determination is that they are not in the same orientation, the received video is inverted by 180 degrees (S14) and displayed on the display 220.

For example, as shown in FIG. 4, it is assumed that a vehicle or the like passing through a road is photographed from above. Then, as shown in FIG. 5, the image is that the vehicle is running upward or downward. When this image is reversed, the image becomes as shown in FIG. 6, and the traveling direction of the own vehicle is directed upward. By such processing, the image displayed on the display 220 matches the traveling direction of the own vehicle. Therefore, it is possible to obtain an image without any discomfort for the passenger.

This image may be an image of the surrounding area including the own vehicle, or may be an image of a far off exit tollgate. Generally, the traveling direction of the vehicle at the shooting location can be estimated from the current traveling direction of the vehicle, but when a route is set,
It is preferable to refer to this.

Further, data on the traveling direction of the vehicle is supplied from the mobile station 200 to the center 112.
It is also preferable to perform a video inversion process in consideration of the traveling direction of the mobile station 200. Further, at the center 112,
If the traveling direction of the vehicle supplying the video is recognized, the video from the camera 110 in the traveling direction may be selected and transmitted to the mobile station 200. For example, a camera 1 that captures images of the up lane and the down lane, respectively.
When there is a mobile station 2, an image from any camera 110 is transmitted based on the lane in which the mobile station 200 is traveling.
00 is controlled. Further, for example, it is also preferable to provide both the camera 110 for photographing the entrance side of the tollgate on the expressway and the camera 110 for photographing the exit side, and to adopt an appropriate one.

In particular, in a system in which a traveling vehicle (mobile station 200) supplies its own destination to the center 112, the center 112 knows the traveling direction of the vehicle. Preferably, a treatment is performed. In this case, the mobile station 200 simply transmits data on a place where a video is desired, and the center 112 supplies a video that meets the request.

"Other Configurations" Further, as shown in FIG. 6, it is also preferable to display on-screen an arrow → indicating the traveling direction of the own vehicle. Thus, the driver or the like can easily recognize the traveling direction of the own vehicle. It is also preferable that the arrow be translucently displayed so that an image below the arrow can be seen.

As shown in FIG. 7, it is also preferable to cut out and display only the image of the lane in the traveling direction of the vehicle from the received image. In addition, in the image of the opposite lane side,
It is also preferable to display an image of a normal navigation (display of the current position on the map and the imaging position). This makes the image more understandable.

In the above example, the road was photographed from above by a camera provided on the side of the road. However, the image is not limited to this, and various images such as images of a vehicle heading for a tollgate and images obtained from a satellite are adopted. In particular, if it shows landscape, etc., the video is not currently being shot,
Photos taken in the past may be used. Also in this case, since the image matches the traveling direction of the own vehicle, the driver or the like does not feel uncomfortable. Further, as the image to be provided to the vehicle, an image during construction, a surrounding image including the own vehicle, and the like are preferable. Further, it is also preferable to display on-screen a traffic congestion point or a traffic stop point in translucent red or the like.
