Vehicle Pillar Display System for Blind Spot Resolution Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The enlargement of blind spots due to thicker vehicle pillars poses a significant safety risk, as existing camera monitoring systems struggle to provide continuous and accurate visual feedback to drivers, leading to recognition errors and discomfort.
Innovation Solution
A vehicle-mounted monitor display system comprising cameras, displays, and an image processing device that captures and processes images of blind spots, reducing the resolution of display images to create a blurry effect, simulating a view through frosted glass, thereby reducing visual recognition errors and discomfort while ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If images of blind spots are displayed on pillar displays with high resolution and precise alignment, then visual accuracy is improved, but device complexity and alignment difficulty increase significantly
Solution Approach 1:
The patent changes the resolution parameter of the displayed image from high to low. By reducing the resolution to create a blurry effect, the system eliminates the need for precise alignment between the display image and the actual blind spot view, thereby resolving the contradiction between visual accuracy and alignment complexity
Solution Approach 2:
The patent introduces an intermediary processing step that transforms the camera image into a blurry low-resolution display image. This intermediary representation acts as a mediator between the camera feed and the driver's visual perception, allowing the system to convey blind spot information without requiring pixel-perfect alignment
2Strength
If the pillar portion is made thicker to improve crash safety, then vehicle safety is improved, but the blind spot area is enlarged
Solution Approach 1:
The patent creates a visual copy of the blind spot area using a camera mounted on the pillar. This camera capture replicates the view that would be visible if the pillar were transparent or thinner, allowing the driver to see around the thicker pillar structure through the displayed image
Solution Approach 2:
The display system acts as an intermediary that bridges the gap created by the thick pillar. By placing a display on the pillar surface that shows camera feeds of the blind spot area, the system mediates between the physical obstruction and the driver's need for visual information
3Measurement precision
If high resolution images are displayed on the pillar, then image detail is improved, but visual recognition errors increase due to discontinuity with real views
Solution Approach 1:
The patent changes the resolution parameter from high to low, creating a blurry effect that matches the driver's natural visual perception when glancing at the pillar display. This parameter change ensures that the displayed image does not create false precision expectations, thereby improving visual recognition reliability
Solution Approach 2:
While not directly addressing color, this principle relates to visual perception characteristics. Similarly, the patent addresses the visual characteristics of the displayed image by controlling its sharpness and resolution to match human visual expectations, preventing recognition errors that would arise from overly sharp, artificial-looking images

AI summary
According to one embodiment, a vehicle-mounted monitor display system includes a camera which captures an image of outside scenery which is a blind spot of a driver created by a pillar, a display which displays an image on the pillar, and an image processing device which generates a display image by cutting out the image captured by the camera in conformity with a display range of the pillar, and outputs the display image to the display. In the image processing device, a resolution of the display image is reduced in a state where a vehicle equipped therewith is moving.
