Vehicular Visual Recognition Device Image Distortion Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular visual recognition systems suffer from image distortion at the boundary positions when combining multiple images, which negatively affects the appearance of the displayed image.
Innovation Solution
A vehicular visual recognition device and method that captures overlapping vehicle exterior images and combines them with a vehicle cabin image, where the vehicle body portion is set to a predetermined transmissive state to overlap with the overlapping areas, making the image of the vehicle body portion overlap with the outside-vehicle-captured images, thus obscuring the distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple vehicle exterior images are combined and displayed from a hypothetical viewpoint, then a wide field of view is achieved, but image distortion occurs at boundary positions
Solution Approach 1:
The patent introduces an intermediary element (the vehicle body portion image with adjusted brightness) to mask the harmful effect of image boundary distortion. By placing a semi-transparent vehicle body image over the boundary regions, the distortion becomes less noticeable while the wide field of view is preserved
Solution Approach 2:
The patent applies brightness adjustment to the vehicle body portion image to make it semi-transparent. This color/brightness change allows the underlying distorted image to still be visible while the vehicle body overlay masks the distortion, resolving the contradiction between wide field of view and image quality
2Manufacturing precision
If image combination boundaries are trimmed to reduce distortion visibility, then appearance is improved, but information loss occurs
Solution Approach 1:
Instead of trimming or removing distorted image portions, the patent uses an intermediary vehicle body image to mask the distortion. This preserves all original image information while making the distortion imperceptible, thus avoiding information loss
3Manufacturing precision
If vehicle body portions are set to transmissive state and overlaid on overlapping image portions, then image distortion is masked, but device complexity increases
Solution Approach 1:
The patent changes the brightness parameter of the vehicle body portion image to create a semi-transparent effect. This simple parameter adjustment allows the vehicle body image to mask distortion while maintaining visibility of the underlying scene, achieving the goal without complex processing

AI summary
A vehicular visual recognition device, including: an imaging section that, from outside a vehicle, captures plural vehicle exterior capture images in which portions of the images overlap with each other; and a controller that effects control such that an image of a vehicle body portion of a vehicle cabin image set to a predetermined transmissive state overlaps with at least part of an overlapping portion of the plural vehicle exterior capture images, and such that the plural vehicle exterior capture images and the vehicle cabin image are combined and displayed at a display section.
