Document Image File Naming via Character Recognition and Date Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems lack an efficient method for automatically generating appropriate file names for document image data, often requiring manual input and lacking integration of document type and date information.
Innovation Solution
An image processing apparatus and program that utilize character recognition to search for specific character strings and extract date information from document image data, generating a file name that includes the detected strings and date information, allowing users to easily set appropriate file names.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If character strings at multiple recognition locations are coupled to generate a file name, then the file name includes document content information, but the file naming process becomes complex and requires multiple recognition locations to be designated in advance
Solution Approach 1:
The invention extracts only the necessary information elements (specific character strings and date information) from the document image data rather than coupling multiple recognition locations. The control unit searches for specific character strings registered in advance and extracts date information, then combines these extracted elements to generate the file name, simplifying the process while preserving essential document information.
2Measurement precision
If manual file name input is required, then file naming accuracy can be ensured, but user effort and time consumption increase
Solution Approach 1:
The system performs self-service by automatically generating file names through character recognition and information extraction. The control unit autonomously searches for specific character strings, extracts date information, and assembles the file name without requiring manual user input, thereby maintaining accuracy while significantly reducing user effort and time consumption.
3Ease of operation
If automatic file name generation is implemented, then user effort is reduced, but the ability to represent document type and date information may be insufficient
Solution Approach 1:
The invention applies preliminary action by registering specific character strings that indicate document types in advance. The control unit searches for these pre-registered character strings in the document image data and combines them with extracted date information to generate comprehensive file names. This approach automatically preserves both document type and date information while reducing user effort.
4Loss of information
If multiple character strings are coupled via sectioning characters, then document content is reflected in the file name, but the file naming system becomes less adaptable to different document types
Solution Approach 1:
The invention applies dynamics by making the file name generation process adaptable to different document types. Instead of using fixed recognition locations, the control unit dynamically searches for specific character strings registered in advance and extracts date information, then combines these elements with sectioning characters to generate file names that adapt to various document types while preserving essential information.
Data Source
AI summary
An image processing apparatus includes a processor that acquires document image data that is generated by reading an original document and recognizes character strings that are included in the document image data through character recognition, and the processor searches for a specific character string registered in advance from the character strings and causes a display unit to display a file name that includes the specific character string detected through the searching as a file name of the document image data. The processor extracts date information from the character strings included in the document image data and causes the extracted date information to be included in the file name to be displayed.
