Thumbnail Index View Position Stabilization During Matrix Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional index view display methods cause the highlighting of a selected thumbnail image to move unpredictably when switching the number of thumbnail images displayed on a screen, making it difficult for users to maintain visibility of the highlighted image.
Innovation Solution
A display control apparatus and method that maintains the selected image's location in a reference position when switching between different matrix arrangements of thumbnail images, ensuring the image remains visible and easily recognizable across screen division changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of thumbnail images displayed on a screen is increased, then the searchability is improved, but the resolution of thumbnail images is reduced
Solution Approach 1:
The patent implements dynamic switching between multiple display modes (index view with multiple thumbnails, single image view, and hybrid view) based on user interaction. The system transitions from a static display mode to a dynamic one where the display configuration changes according to user selection behavior, allowing optimization between searchability and resolution in different contexts.
2Manufacturing precision
If the number of thumbnail images displayed on a screen is reduced, then the resolution of thumbnail images is improved, but the searchability is impaired
Solution Approach 1:
The system dynamically adjusts the display mode based on user interaction. When users select a thumbnail, the system transitions to a detailed view mode, effectively providing high resolution when needed while maintaining efficient browsing in index view mode, thus resolving the contradiction between resolution and searchability.
3Adaptability or versatility
If the matrix arrangement of thumbnail images is changed, then the display flexibility is improved, but the position of the highlighted image becomes unpredictable
Solution Approach 1:
The patent replaces the conventional matrix-based mechanical arrangement system with a coordinate-based positioning system. Instead of relying on fixed matrix positions that change with arrangement changes, the system uses absolute coordinates to track and maintain the highlighted image position, ensuring predictability regardless of the matrix configuration.
4Ease of operation
If the highlighting position is based on the image number order, then the arrangement is systematic, but the highlighting moves when switching display modes
Solution Approach 1:
The system substitutes the image-number-based positioning mechanism with a coordinate-based positioning mechanism. By calculating and maintaining absolute coordinates of the highlighted image, the system ensures that the highlighting position remains stable and predictable even when switching between different display modes and matrix arrangements, while still maintaining systematic arrangement through coordinate ordering.

AI summary
A display control apparatus that makes it easy to recognize a target image when images are displayed in each of regions obtained by dividing a single screen, even when the method for dividing the screen has changed. For example, when the method for dividing the screen in an index view is switched, the post-switch location of a target thumbnail image is calculated based on the ratio between the pre- and post-switch division numbers and the pre-switch location of the target thumbnail image, in both the horizontal and vertical directions. Then, the overall arrangement of the thumbnail images in the index view after the division method switch is determined based on the calculated location of the target thumbnail image.
