The terminal communication unit 19 receives the driving support information including the information on the driving caution points around the vehicle M and the route guidance information generated in the server device 10B based on the transmitted movement information (step S103).

Based on the received driving support information, the terminal control unit 13 specifies a guide point such as a driving caution point or an intersection located in the traveling direction of the vehicle M, and the current position of the vehicle M is within a predetermined distance from the guide point. It is determined whether it is within (step S104).

If it is determined that the current position of the vehicle M is not within a predetermined distance from the guidance point (step S104: No), the terminal control unit 13 controls the image processing unit 14 to support driving of the moving object. A sky support image for displaying the image at a position above the landscape image is generated. Based on the driving support information received in step S103, the image processing unit 14 generates a driving support image including a driving attention point instruction image indicating a driving attention point and a route guidance image as an aerial support image (step S105).

On the other hand, if it is determined that the current position of the vehicle M is within a predetermined distance from the guidance point (step S104: Yes), the terminal control unit 13 controls the image processing unit 14 to capture a landscape image captured by the camera 11. Analysis is performed to determine whether there is an obstacle such as a forward vehicle on the road surface ahead of the vehicle M (step S106).

If it is determined that there is no obstacle in front of the vehicle M (step S106: No), the terminal control unit 13 stores the landscape image captured by the camera 11 in the terminal storage unit 12 (step S107). At the same time, the image information of the landscape image photographed by the camera 11 may be transmitted to the server device 10B together with the position information of the vehicle M at the time of photographing, the traveling direction information, and the photographing date / time information.

If it is determined that there is an obstacle ahead of the vehicle M (step S106: Yes), an obstacle transmission process for generating a transparent image showing the scenery around the vehicle M while passing through a part of the obstacle (for example, the inside). Is executed (step S108).

The image processing unit 14 aligns the landscape image photographed by the camera 11 and the substitute image (step S205). For example, the image processing unit 14 detects a characteristic object (feature part) that is included in both images in common, and performs alignment so that the degree of matching of the position of the characteristic object becomes high.

After completion of alignment, the image processing unit 14 detects the edge of the obstacle included in the landscape image (step S206).

The image processing unit 14 corresponds to a region to be superimposed on the obstacle in the landscape image captured by the camera 11 in the substitute image (that is, corresponding to the position of the obstacle in the substitute image) using the detected edge of the obstacle as a reference. Area to be trimmed (step S207).

The image processing unit 14 superimposes the trimmed substitute image on the landscape image, and generates a transmission image in which a part (for example, the inside) of the obstacle in the landscape image is transmitted in a pseudo manner (step S208). At that time, the image processing unit 14 generates a transmission image while changing the transmission degree of the obstacle (for example, translucent, fully transparent, etc.) according to the distance from the vehicle M to the guide point, for example.

Referring to FIG. 3 again, the terminal control unit 13 controls the image processing unit 14 to generate a road surface support image for displaying a driving support image that supports driving of the moving body on the road surface of the landscape image. Based on the driving support information received in step S103, the image processing unit 14 generates a driving support image including a driving attention point instruction image indicating a driving attention point and a route guidance image as a road surface support image (step S109).

The terminal control unit 13 controls the display unit 15 so that the camera 11 captures the sky support image generated by the image processing unit 14 in step S105 or the road surface support image generated in step S109, or the obstacle in step S108. The image is superimposed and displayed on the transmission image generated by the object transmission process (step S110).

Displayed.

FIG. 5C is a diagram illustrating an example of an image displayed on the display unit 15 when the vehicle M approaches the guidance point. When the vehicle M approaches the guidance point, the front vehicle FV is detected as an obstacle, and a transmission image showing the inside of the front vehicle FV is displayed. At that time, the degree of transmission of the forward vehicle FV changes according to the distance between the vehicle M and the guide point, and the forward vehicle FV is gradually transparent as the vehicle M approaches the guide point (for example, a translucent state) To be completely transparent).

FIG. 5D is a diagram illustrating an example of an image displayed on the display unit 15 when the vehicle M further approaches the guidance point. When the vehicle M approaches the guidance point further than the state shown in FIG. 5C, the interior of the front vehicle FV that is an obstacle is displayed in a completely transparent state. In that case, in order to show the position of the front vehicle FV, the outline image FVC which shows the outline of the front vehicle FV, for example is displayed.

FIG. 5E is a diagram illustrating another example of an image displayed on the display unit 15 when the vehicle M approaches the guidance point. Here, instead of displaying the outline through the inside of the front vehicle FV, which is an obstacle, an example is shown in which the upper portion of the front vehicle FV is displayed and the lower portion (portion overlapping the road surface) is transmitted. ing. As described above, the transmission image may be an image that transmits through a portion of the obstacle where the driving assistance image overlaps.

Heretofore, the example in which the information display terminal 10A generates the driving support image based on the driving support information received from the server device 10B has been described.

You may change the size. For example, when there is an obstacle such as a preceding vehicle in the traveling direction of the vehicle M and the distance to the guide point is equal to or greater than a predetermined distance, the display unit 15 is positioned at the first height (for example, the sky). A driving assistance image is displayed, and when there is no obstacle and the distance to the guide point is equal to or greater than a predetermined distance, a second height position lower than the first height (for example, several meters from the road surface) When the distance to the guide point is less than the predetermined distance, the third height (lower than the second height) is displayed regardless of the presence or absence of obstacles. For example, a configuration in which a driving assistance image is displayed at a position on the road surface may be employed.
