Multi-Display Boundary Image Readability via Dummy Data Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-display devices experience distortion at boundary areas due to bezels, which affects the readability of images displayed across adjacent screens.
Innovation Solution
The method involves determining if a boundary area image needs modification based on image data changes and inserting dummy data to increase the image size, ensuring objects are displayed outside the boundary area, thereby improving readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entire image is displayed by dividing it into multiple partial images on adjacent displays, then the overall display area is increased, but distortion occurs at the boundary area due to bezels
Solution Approach 1:
The patent extracts the problematic boundary area from the displayable region by determining a boundary area image that corresponds to the bezel region. This extracted boundary area is then handled separately by inserting dummy data, effectively removing the distortion source from the visible image content while preserving the overall display area benefit.
Solution Approach 2:
Dummy data is introduced as an intermediary element between the image content and the boundary bezel. This dummy data acts as a buffer that separates the actual image content from the problematic boundary area, allowing the image to be displayed without distortion while maintaining the multi-display configuration.
2Area of stationary object
If the image is displayed unmodified on the boundary area, then the display coverage is maximized, but the readability of objects in the boundary area deteriorates
Solution Approach 1:
The patent applies different handling to different regions of the image. The boundary area image is identified as having different quality characteristics (higher chroma change or frequency change) compared to the central area. By applying local quality analysis, the system selectively modifies only the boundary region while leaving the central image content unchanged, thus maintaining overall display coverage while improving readability in the problematic boundary area.
3Reliability
If dummy data is inserted to modify the boundary area image, then the readability is improved, but the image processing complexity increases
Solution Approach 1:
The system performs preliminary analysis of the image data to identify boundary area images before actual display. By determining in advance which regions require modification based on chroma or frequency change thresholds, the system can prepare and insert dummy data efficiently, avoiding unnecessary processing of the entire image and reducing overall processing complexity.
Solution Approach 2:
The patent uses parameter changes (chroma change amount and frequency change amount) as criteria to automatically identify boundary area images. By thresholding these parameters, the system can quickly distinguish between regions that need dummy data insertion and those that don't, simplifying the decision-making process and reducing processing complexity compared to manual analysis.

AI summary
According to one embodiment of the present disclosure, a method for displaying an image on a multi-display device including two or more displays comprises determining whether the image includes a boundary area image to be displayed over a boundary area between a first display and a second display adjacent to the first display; and inserting dummy data into the image so that the image has an increased size and the dummy data is displayed on a position corresponding to the boundary area.
