Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for displaying video images of an outside area of a moving body, such as vehicles, lack convenience and effectiveness in providing clear and timely warnings or indicators of potential collisions or obstacles.
Innovation Solution
A display system comprising an imaging apparatus, image processing apparatus, and display apparatus that superimposes markers and images on video images based on the relative positions and movements of detected objects, dynamically changing display modes to indicate potential collisions or obstacles, using algorithms for object detection and path prediction.

Engineering Contradiction Analysis
1Reliability
If video images of outside areas are displayed without additional processing, then the display system remains simple, but the ability to provide clear and timely warnings of potential collisions or obstacles is insufficient
Solution Approach 1:
The patent segments the video image into multiple regions (first region, second region, third region) based on distance from the vehicle. Different display treatments are applied to each region: the first region (closest) receives first display treatment, the second region receives second display treatment, and the third region receives third display treatment. This segmentation enables prioritized display of critical obstacles while maintaining overall situational awareness, thereby improving collision warning capability without requiring complete system redesign.
Solution Approach 2:
Different display treatments are applied to different regions of the video image based on their distance from the vehicle. The first region (closest to vehicle) receives enhanced display treatment (e.g., brighter, more prominent) compared to the second and third regions. This local quality differentiation ensures that critical near-field obstacles receive maximum attention while maintaining context from farther regions, improving reliability without uniform complexity increase.
2Loss of information
If multiple display treatments are applied to different regions, then the clarity of obstacle warnings is improved, but the processing complexity increases
Solution Approach 1:
The system performs preliminary segmentation of the video image into distance-based regions before applying display treatments. By pre-defining the first, second, and third regions based on distance thresholds, the system prepares the spatial structure in advance, making subsequent application of different display treatments more efficient and less computationally intensive during real-time operation.
Solution Approach 2:
The display treatments are dynamically adjusted based on the detected distance of obstacles from the vehicle. As obstacles move between regions (e.g., from third region to second region to first region), their display treatment changes automatically. This dynamic adaptation maintains optimal information clarity without requiring manual reconfiguration or complex static processing for all possible scenarios.
3Loss of time
If the system processes and displays multiple regions with different treatments, then the timeliness of collision warnings is improved, but the computational load increases
Solution Approach 1:
The system applies full processing and enhanced display treatment only to the first region (closest obstacles), while applying simplified treatments to the second and third regions. This partial action approach focuses computational resources on the most critical area (near-field obstacles) where timely warnings are most important, rather than uniformly processing all regions with equal detail, thereby reducing overall computational load while maintaining warning timeliness for critical threats.

AI summary
A display control apparatus comprising a controller configured to superimpose a first image on a right-side edge region or a left-side edge region of a first video image of a rear area behind a vehicle depending on a position of a first object when a distance between the vehicle and the first object present at right rear side or left rear side of the vehicle decreases while the vehicle is moving at a moving speed smaller than a reference value, and superimpose a second image in a display mode different from the first image on the first video when a distance between the vehicle and a second object behind the vehicle becomes less than a predetermined threshold while the vehicle is moving.
