Vibration-Compensated Display System for Mobile Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems on mobile bodies, such as vehicles, face challenges in reducing image blurring due to vibrations affecting both imaging and display apparatuses, as conventional image stabilization methods are insufficient when these components are installed at different positions.
Innovation Solution
A display system comprising imaging and display apparatuses with sensors to detect vibrations, and image processors that clip out regions of images to counteract vibrations at the imaging apparatus and follow vibrations at the display apparatus, ensuring reduced blurring by adjusting the image processing accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image stabilization is applied only at the imaging apparatus, then vibration effects at the imaging apparatus are reduced, but blurring occurs due to vibration at the display apparatus
Solution Approach 1:
The image processing function is segmented into two independent processing stages: first image processing at the imaging apparatus and second image processing at the display apparatus. Each stage handles vibration compensation independently based on local vibration detection, allowing both imaging and display vibrations to be addressed separately rather than relying on a single stabilization point
Solution Approach 2:
Vibration detection sensors act as intermediaries between the physical vibration environment and the image processing systems. The first sensor detects vibration at the imaging apparatus and the second sensor detects vibration at the display apparatus, providing intermediate measurement data that enables each processing stage to compensate for its local vibration conditions
2Adaptability or versatility
If the display apparatus is installed at a different position from the imaging apparatus, then system flexibility is improved, but vibration effects cannot be fully compensated due to position differences
Solution Approach 1:
The vibration compensation system is divided into two independent modules: one at the imaging apparatus and one at the display apparatus. This segmentation allows each module to operate independently based on its local vibration conditions, enabling the system to function effectively even when the components are installed at different positions with different vibration characteristics
Solution Approach 2:
Each apparatus (imaging and display) performs image processing based on its own local vibration detection. The first image processing uses vibration data from the first sensor at the imaging apparatus location, while the second image processing uses vibration data from the second sensor at the display apparatus location, allowing each location to be optimized for its specific vibration environment

AI summary
A display system includes an imaging apparatus installed on a mobile body; a display apparatus installed at a position different from that of the imaging apparatus on the mobile body and displaying a post-processing image; a first sensor detecting vibration at or near the imaging apparatus; a second sensor detecting vibration at or near the display apparatus; a first image processor clipping out a preprocessing image from an image captured by the imaging apparatus, based on the first sensor detection result; and a second image processor clipping out the post-processing image from the preprocessing image based on the second sensor detection result. The first image processor moves a clip-out region of the preprocessing image in a direction to counteract vibration at or near the imaging apparatus, and the second image processor causes a clip-out region of the post-processing image to follow vibration at or near the display apparatus.
