Rear Side Camera Display Blur Processing for Mirror-Like Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rear side image display systems using cameras lose depth perception and cause a feeling of strangeness for drivers accustomed to traditional door mirrors due to the entire imaging range being in focus, including the side surface of the vehicle body, which blurs the distinction between the vehicle and surrounding objects.
Innovation Solution
A vehicle rear side image display device that employs imaging and blur processing to selectively blur the partial image corresponding to the vehicle's side surface, while maintaining clarity for distant views, using methods like reducing resolution or Gaussian blurring, to mimic the depth perception of traditional door mirrors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire imaging range is displayed in focus, then the clarity of the image is improved, but the depth perception is lost and a feeling of strangeness occurs
Solution Approach 1:
The patent applies different image processing qualities to different regions of the image. The partial image corresponding to the vehicle side surface undergoes blur processing, while other regions maintain normal clarity. This creates local quality differentiation that restores depth perception by making the side surface region appear out of focus, similar to traditional door mirrors.
2Measurement precision
If the side surface of the vehicle body is clearly displayed, then the imaging accuracy is improved, but the distinction between the vehicle and surrounding objects is blurred
Solution Approach 1:
The patent extracts the partial image corresponding to the vehicle side surface from the entire rear side image. This extracted portion is then subjected to blur processing and overlaid on the main image. By separating and selectively processing this region, the patent removes the harmful effect of clear side surface display while preserving the overall imaging accuracy.
3Area of stationary object
If a camera with deep subject depth is used, then the imaging range is expanded, but the sense of depth is lost
Solution Approach 1:
The patent maintains the advantage of deep subject depth for expanded imaging range while compensating for the loss of depth sense by applying blur processing locally to the side surface region. This allows the camera to capture a wide area including the vehicle side surface and distant objects, while the selective blurring restores the perception of depth by creating a focus gradient similar to traditional mirrors.
