When the information about the weather around the vehicle indicates stormy weather, the display control unit 55 widens the display range of the bird's-eye view image 100 generated by the bird's-eye view image generation unit 54 and causes the display unit 21 to display the bird's-eye view image 100 . The display control unit 55 may determine that the weather information acquired by the environment information acquisition unit 52 indicates stormy weather when it indicates at least one of rainfall, snowfall, strong wind, and cold snap. It includes, but is not limited to, rain, snow, high winds and cold weather, and other weather conditions that reduce visibility around the vehicle.

Next, the flow of processing in the display control device 50 of the display system 1 will be described using FIG. FIG. 3 is a flow chart showing an example of the flow of processing in the display control device of the display system according to the first embodiment.

When the display system 1 is activated, the display control device 50 acquires peripheral image data with the image data acquisition unit 51 . The display control device 50 acquires vehicle information with a vehicle information acquisition unit 53 .

The display control device 50 determines whether or not to start bird's-eye view image display (step S101). For example, based on the vehicle information acquired by the vehicle information acquisition unit 53, the display control device 50 displays the bird's-eye view image when the shift position is set to "reverse" or when the traveling direction of the vehicle is backward. Determine to start. For example, based on the vehicle information acquired by the vehicle information acquisition unit 53, the display control device 50 may determine to start the overhead view image display when an instruction to display the overhead view image 100 based on the user's operation is detected. . When the display control device 50 determines to start the bird's-eye view image display (Yes in step S101), the process proceeds to step S102. When the display control device 50 does not determine to start the bird's-eye view image display (No in step S101), the process of step S101 is executed again.

When it is determined to start bird's-eye view image display (Yes in step S101), the display control device 50 acquires environment information by the environment information acquisition unit 52 (step S102). The display control device 50 proceeds to step S103.

The display control device 50 generates the bird's-eye view image 100 (step S103). More specifically, the display control device 50 generates the bird's-eye view image 100 using the bird's-eye image generation unit 54 . The display control device 50 proceeds to step S104.

The display control device 50 determines whether or not the environment information indicates stormy weather (step S104). More specifically, based on the environmental information acquired by the environmental information acquiring unit 52, the display control device 50 determines that the environmental information indicates stormy weather when it indicates at least one of rainfall, snowfall, strong wind, and cold weather. I judge. When the display control device 50 determines that the environment information indicates stormy weather (Yes in step S104), the process proceeds to step S105. When the display control device 50 does not determine that the environment information indicates stormy weather (No in step S104), the process proceeds to step S106.

When it is determined that the environmental information indicates stormy weather (Yes in step S104), the display control device 50 displays the bird's-eye view image 100 with a wider display range than usual (step S105). More specifically, as shown in FIG. 4, the display control device 50 outputs a video signal that causes the display unit 21 to display the bird's-eye view image 100 generated by the bird's-eye image generation unit 54 in a wider display range than usual. FIG. 4 is a diagram showing another example of a bird's-eye view image generated by the display control device of the display system according to the first embodiment. In the bird's-eye view image 100 shown in FIG. 4, the front image 101, the rear image 102, the left side image 103, and the right side image 104 are displayed wider than the normal bird's-eye view image 100 shown in FIG. ing. The bird's-eye view image 100 shown in FIG. 4 has a smaller vehicle icon 110 than the normal bird's-eye view image 100 shown in FIG. The display control device 50 proceeds to step S107.

If it is not determined that the environmental information indicates stormy weather (No in step S104), the display control device 50 displays the bird's-eye view image 100 in the normal display range (step S106). More specifically, the display control device 50 outputs a video signal that causes the display unit 21 to display the bird's-eye view image 100 generated by the bird's-eye image generation unit 54 as shown in FIG. 2 in the normal display range. The display control device 50 proceeds to step S107.

The display control device 50 determines whether or not to end the bird's-eye view image display (step S107). More specifically, based on the vehicle information acquired by the vehicle information acquisition unit 53, the display control device 50 detects that the shift position has been changed from "reverse" to "drive" or that the traveling direction of the vehicle has changed to the front. If so, it is determined to end the bird's-eye view image display. For example, based on the vehicle information acquired by the vehicle information acquisition unit 53, the display control device 50 may determine to end the overhead view video display when an instruction to end the display of the overhead view video 100 based on the user's operation is detected. good. When the display control device 50 determines to end the bird's-eye view image display (Yes in step S107), the process ends. When the display control device 50 does not determine to end the bird's-eye view image display (No in step S107), the process of step S107 is executed again.

In this manner, the display range of the bird's-eye view image 100 is changed and displayed based on the environmental information around the vehicle.

As described above, according to the present embodiment, the bird's-eye view image 100 can be appropriately displayed according to the environment around the vehicle. The embodiment can change the display range of the bird's-eye view image 100 widely and display it when the information about the weather around the vehicle indicates, for example, stormy weather such as rainfall, snowfall, strong wind, and cold weather. As a result, in the present embodiment, when it is difficult for the driver to visually confirm the surroundings such as other vehicles and pedestrians, the bird's-eye view image 100 is displayed by widening the display range. can assist in confirming the status of Further, in this embodiment, by widening the display range of the bird's-eye view image 100 and displaying it, it is possible to make it easier to find other vehicles approaching even when visibility around the vehicle is poor.
