Vehicle Periphery Display Visual Field Range Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera monitoring systems for vehicles lack the ability to intuitively adjust the visual field range, making it difficult for drivers to set an appropriate display range, especially in environments where lane division lines and other vehicles are not reflected, leading to uncertainty in adjusting the display range effectively.
Innovation Solution
A vehicle periphery display system that includes an image capturing device, a display control device, and a display device, which generates a visual field range adjustment screen with computer graphics indicating a first range in a reduced state and a second range without reduction, allowing drivers to intuitively set the visual field range by displaying a bird's-eye view and rear view with indicators for equal magnification and reduction areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image capturing device captures images in environments like garages where road or vehicles are not visible, then the captured images lack reference objects for adjustment, but the driver still needs to set the visual field range appropriately
Solution Approach 1:
The system generates computer graphics that copy and represent the visual field range adjustment information in an alternative form. Instead of relying on captured images of road or vehicles as references, the system creates synthetic graphical representations that display the visual field range boundaries and adjustment states, providing reference information without requiring actual environmental features
Solution Approach 2:
The system introduces computer graphics as an intermediary between the image capturing device and the display. These graphics serve as a mediator that provides visual field range adjustment references independent of the captured image content, allowing drivers to adjust settings even when the environment lacks natural reference objects
2Area of stationary object
If the display shows the entire captured image without reduction, then all details are visible, but the display area required increases and may not fit the monitor
Solution Approach 1:
The display is segmented into multiple regions: the main captured image area and a separate visual field range adjustment screen area. The computer graphics displaying visual field range information are placed in the adjustment screen area, allowing the main image to be displayed at full size without losing the visual field range information, which is presented in a dedicated separate region
Solution Approach 2:
The system adds a new dimensional layer to the display by introducing a visual field range adjustment screen that exists alongside the main captured image display. This creates a multi-layered display structure where visual field range information is presented in a separate dimensional space, allowing both full-image display and adjustment information to coexist without competing for the same display area
3Area of stationary object
If the display reduces the image to fit the monitor, then the display area is optimized, but it becomes difficult to know the visual field range
Solution Approach 1:
The system creates computer graphics that copy the visual field range adjustment information and displays it in a dedicated visual field range adjustment screen. This graphical copy provides clear visual field range boundaries and adjustment states independent of the main reduced captured image, ensuring visibility is maintained even when the main image is scaled down to fit the monitor

AI summary
A display control device generates a display image including an image obtained by reducing a predetermined range in a captured image based on an image captured by an image capturing device, and causes the display device to display the display image. In an adjustment mode, the display control device generates a computer graphics (CG) for allowing a user to set a range included in the display image and causes the display device to display the computer graphics. The CG indicates a range displayed in a reduced state and a range displayed without being reduced in a range included in the display image in different aspects.
