Document Image Character Recognition Area Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in designating appropriate text data from a document image due to multiple potential text data targets, making it hard to set correct information for file names and metadata.
Innovation Solution
An information processing apparatus that includes a character recognition unit, a display control unit, a detection unit, and an extraction unit to obtain and display scanned document images, detect user selections, and extract character recognition areas that satisfy verification rules, highlighting these areas for easy user identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple text data targets are provided in the document image, then the user has more options for selection, but it becomes difficult for the user to designate the appropriate text data
Solution Approach 1:
The patent applies color changes by highlighting the character recognition area that satisfies the verification rule with a different color or background shade. This visual distinction helps users quickly identify the correct text data target among multiple options in the document image, resolving the contradiction between providing multiple targets and making selection easy.
2Measurement precision
If verification rules are applied to setting items, then the accuracy of text data selection is improved, but the complexity of the system increases
Solution Approach 1:
The system performs self-service by automatically extracting character recognition results, applying verification rules, and highlighting the matching area without requiring manual user configuration. The verification rule is automatically obtained and applied to the selected setting item, reducing system complexity while maintaining high accuracy in text data selection.
3Ease of operation
If the character recognition area is highlighted, then the user can easily identify the designation target, but the display complexity increases
Solution Approach 1:
The patent uses color changes to highlight the character recognition area in the display image. This simple visual modification effectively improves user identification of the designation target while adding minimal complexity to the display system, as it only requires overlaying a visual indicator on the existing image.
Data Source
AI summary
Results of character recognition processing for a scanned image of a document and a setting item set to a property attached to the scanned image of a document are obtained. Displaying on a screen having a preview area where the scanned image of a document is displayed and an editing area where information input in the setting item is edited, that is, displaying the scanned image of a document in the preview area and displaying the setting item and the information in the editing area are controlled. A selection for the setting item displayed in the editing area is detected. A verification rule set to the detected setting item is obtained. A character recognition area satisfying the verification rule is extracted from the results of the character recognition processing. A character recognition area displayed on the preview area and extracted is highlighted.
