Image Display Apparatus Thumbnail Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies on small screens, such as personal computers and smartphones, require users to repeatedly scroll, enlarge, and reduce document images, making it cumbersome to view desired portions due to limitations in adjusting display size and position.
Innovation Solution
An image display apparatus with a setting unit to adjust display magnification and position based on object attributes, allowing for easy viewing of each object on the screen through a specified display mode, and a display control unit to control the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually scroll, enlarge, and reduce document images on small screens, then the display can be adjusted to show different portions, but the operation becomes troublesome and complicated
Solution Approach 1:
The system pre-processes the document image into multiple thumbnail images representing different portions before display. When a user selects a thumbnail, the corresponding full-size image is immediately displayed without requiring manual scrolling or zooming operations, thus performing the adjustment action in advance.
Solution Approach 2:
Thumbnail images serve as an intermediary between the user and the full document image. Instead of directly manipulating the large document image through scrolling and zooming, users interact with small thumbnail representations that map to specific portions, simplifying the interaction process.
2Measurement precision
If the document image is displayed at 100% magnification sequentially according to reading order, then each region can be viewed in detail, but the display size of each region cannot be adjusted
Solution Approach 1:
The display magnification is made dynamic rather than fixed. The system can switch between displaying multiple thumbnails at reduced size and displaying a selected thumbnail's corresponding full image at 100% magnification, allowing the display to adapt to different viewing needs.
Solution Approach 2:
The document image is segmented into multiple portions represented as separate thumbnail images. Each thumbnail can be independently selected and displayed, allowing users to view specific regions in detail while maintaining the ability to see other portions through the thumbnail overview.
3Productivity
If arrow key operations are used to navigate document regions, then sequential display according to reading order is achieved, but the technique does not accommodate swipe operations or enlarging/reducing operations
Solution Approach 1:
The system is designed to support multiple input methods universally. It accepts both traditional arrow key operations for sequential navigation and modern touch operations (swipe gestures, pinch-to-zoom) through the thumbnail interface, making it adaptable to different user preferences and device types.
Solution Approach 2:
The system creates thumbnail copies of different document portions that can be interacted with independently. These thumbnails serve as simplified representations that respond to various input methods, decoupling the navigation logic from the input mechanism and enabling versatile operation modes.

AI summary
An image display apparatus for displaying an image containing a plurality of objects includes a setting unit configured to set a display magnification and a display position according to an attribute of a display target object when a first display mode for displaying each object included in the image is specified, and a display control unit configured to perform control to display on a screen the image containing the display target object based on the display magnification and the display position set by the setting unit.
