Image Display Apparatus Focused Area Sub-Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display apparatuses face challenges in responsiveness and usability when performing character or object recognition on high-resolution scene images captured by cameras, particularly in mobile terminals, due to increased recognition time and the need to effectively overlay recognition results on wide-area images, which can lead to unnoticed results and difficulties for users with visual impairments.
Innovation Solution
An image display apparatus that detects focused areas in an input image, generates sub-images through size, distortion, and color corrections, and displays them alongside the original image with a screen representation showing the correspondence relation, thereby improving visibility and guiding user attention, while also providing recovery functions for incorrect recognition and detection errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If recognition process is performed on high-resolution scene images, then recognition accuracy is improved, but recognition time increases
Solution Approach 1:
The patent divides the high-resolution scene image into multiple sub-images based on detected focused areas. Each sub-image is processed independently for recognition, allowing parallel computation. This segmentation reduces the overall recognition time while maintaining accuracy by focusing computational resources on relevant regions rather than processing the entire high-resolution image.
Solution Approach 2:
The patent performs focus detection and sub-image extraction before the full recognition process. By pre-identifying focused areas and preparing sub-images in advance, the system reduces the computational load during the main recognition phase, thereby decreasing recognition time while preserving accuracy on the most important regions.
2Area of stationary object
If wide-area scene images are displayed, then field of view is improved, but recognition results become difficult to notice
Solution Approach 1:
The patent applies different display qualities to different regions of the wide-area image. Focused areas are displayed with higher quality and prominence, while peripheral areas are displayed with lower quality. This local differentiation ensures that recognition results in focused areas are easily noticeable while maintaining the wide field of view, solving the contradiction between display area and result visibility.
Solution Approach 2:
The patent overlays recognition results in a different dimensional layer on top of the wide-area scene image. By using transparency and layered display, recognition results are made visible without reducing the field of view of the underlying scene image. This dimensional separation allows both wide viewing area and prominent result display to coexist.
3Loss of information
If sub-images are generated for all focused areas, then completeness of information is improved, but device complexity increases
Solution Approach 1:
The patent generates sub-images for focused areas based on priority thresholds rather than processing all detected areas equally. By applying partial action to only the most important focused areas, the system maintains information completeness for critical regions while reducing processing complexity by excluding less important areas from sub-image generation.
Data Source
AI summary
According to an embodiment, an image display apparatus includes a detection unit, a generation unit, and a display control unit. The detection unit detects areas to be focused in an input image. The generation unit generates a sub image by performing correction for improving visibility on an image of the detected area. The correction includes at least one of size correction for adjusting size of the image of the area, color correction for adjusting color of the image of the area, and distortion correction for transforming the image of the area so as to be an image acquired by viewing the image of the area from the front side. The display control unit displays the generated sub image on a display device together with the input image in a form that accompanies a screen representation representing a correspondence relation with the area.
