Priority-Based Image Aspect Ratio Adjustment for Non-Square Pixels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems struggle to appropriately display content images on displays with non-square pixels, leading to parts of the image being cut off or distorted, especially when the aspect ratios of the content and display do not match, which can result in important information being lost or viewer discomfort.
Innovation Solution
An image processing apparatus that adjusts the aspect ratio of content images by dividing them into partial areas with different adjustment priorities, allowing for selective changes such as enlargement, reduction, or deletion based on the importance of each area to ensure accurate display on displays with non-square pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the aspect ratio of the content image is adjusted to fit the display screen, then the image fits the display properly, but parts of the image may be cut off or distorted
Solution Approach 1:
The content image is divided into multiple regions (e.g., important region and less important region) based on their significance. Different aspect ratio adjustment strategies are applied to each region: the important region maintains its original aspect ratio to preserve content integrity, while the less important region is stretched or compressed to fill the display screen, thereby achieving overall adaptability without significant information loss.
Solution Approach 2:
Different quality requirements are applied to different parts of the image. The important region (e.g., central area containing key content) is protected from distortion by maintaining its original aspect ratio, while the peripheral or less important regions are adjusted to match the display aspect ratio. This local differentiation ensures that critical information remains intact while achieving overall screen coverage.
2Manufacturing precision
If the content image is displayed without aspect ratio adjustment, then the original image quality is maintained, but the image does not fit the display screen properly
Solution Approach 1:
The image is segmented into regions with different fidelity requirements. The important region maintains high fidelity by preserving its original aspect ratio, while the less important region accepts lower fidelity adjustments to achieve display compatibility. This segmentation allows the system to maintain overall image quality while achieving proper screen fitting.
Solution Approach 2:
Different quality levels are applied locally across the image. Critical areas (e.g., center region containing main content) retain their original quality and aspect ratio, while peripheral areas are adjusted to match the display aspect ratio. This creates a quality gradient that prioritizes important content while achieving display compatibility.
3Adaptability or versatility
If uniform aspect ratio adjustment is applied to the entire content image, then the display fit is improved, but important content may be distorted or cut off
Solution Approach 1:
The image is divided into important and less important regions. The important region is excluded from uniform aspect ratio adjustment, ensuring its content integrity is preserved. The less important region undergoes the adjustment to achieve screen coverage. This segmentation strategy ensures that critical content remains reliable while achieving overall display adaptability.
Solution Approach 2:
Different reliability requirements are applied to different image regions. The important region maintains high reliability by resisting aspect ratio changes, while the less important region accepts adjustments to improve screen coverage. This local differentiation protects critical content from distortion while achieving proper display fitting.

AI summary
An image processing apparatus includes an image generator and a display adjuster. The image generator generates a content image. The display adjuster adjusts an aspect ratio of the content image. The content image is divided into plural partial content areas. The content image is displayed on a display screen. A predetermined adjustment priority is set for each of the partial content areas. The display adjuster adjusts the aspect ratio of the content image by changing an aspect ratio for each of the partial content areas on the basis of the adjustment priority.
