Dynamic Character List Synchronization for Document Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying a list of character strings extracted from image data fail to adapt appropriately when the display area of the image is changed, such as through zooming or panning, leading to inefficient user interface operations.
Innovation Solution
A client terminal is configured to perform character recognition on image data and dynamically control the display of character strings based on user instructions, ensuring that the list of recognized characters is updated in real-time with changes to the displayed image area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area of image data is changed through zooming or panning, then the user can focus on specific regions or view different areas, but the list of character strings cannot be displayed appropriately
Solution Approach 1:
The patent implements dynamic synchronization between the image display area and the character string list. When the user zooms or pans the image, the system dynamically updates the list of character strings to correspond to the current visible region, ensuring the list always reflects the displayed area accurately.
Solution Approach 2:
The system establishes a feedback mechanism where changes in the display area (zoom/pan operations) are detected and fed back to update the character string list. This ensures the list continuously adapts to the current view, maintaining accuracy and relevance of displayed character strings.
2Ease of operation
If a fixed list of character strings is displayed for the entire image, then the list remains simple and stable, but it cannot adapt when the display area changes
Solution Approach 1:
The character string list transitions from a static fixed list to a dynamic adaptive list that automatically reconfigures based on the displayed image region. This allows the system to maintain simplicity in its basic structure while gaining the ability to respond to user interactions like zooming and panning.
Solution Approach 2:
The system performs preliminary identification and preparation of character strings for the current display area before the user needs to interact with them. When zooming or panning occurs, the system has already prepared the relevant character string list, enabling smooth and immediate adaptation without delay.

AI summary
A client terminal configured to acquire image data acquired from a document, perform character recognition processing on the image data, and control display of at least a partial area of the image data specified based on an instruction issued by a user and display of a list of character strings acquired by the character recognition processing. As at least the partial area to be displayed is changed, the list of character strings is changed so that character strings recognized in at least the partial area are displayed.
