Image Processing File Naming with Document and Page Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple-page image files generated by an auto document feeder in image processing apparatuses is inefficient due to sequential file naming, making it difficult to organize and identify files in units of pages.
Innovation Solution
An image processing apparatus that assigns a variable character string as a file identifier for each page, with the same string repeated for each unit of pages, allowing for easy identification of file groups and reducing management effort by using a controller to determine file names with a document identifier, group identifier, and file extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sequential numbering is used for file names, then file management in units of one page is simplified, but file management in units of multiple pages becomes difficult and time-consuming
Solution Approach 1:
The patent segments the file name into distinct components: document identifier (representing multiple-page units), page number (individual page identification), and file extension. This segmentation allows users to easily identify and manage files in both single-page and multiple-page contexts by examining different parts of the filename structure.
Solution Approach 2:
The patent applies local quality by assigning different naming conventions to different parts of the filename based on their functional requirements. The document identifier portion uses a consistent format for grouping related pages, while the page number portion uses sequential numbering for individual identification, optimizing each segment for its specific purpose.
2Loss of information
If sequential numbers and alphabets are used for file names, then one-page file management is easy, but identification of file groups in units of multiple pages requires significant effort
Solution Approach 1:
The filename is segmented into a document identifier component that remains constant for all pages of a multi-page document, and a page number component that varies sequentially. This structure preserves information about file groupings while maintaining simplicity in the naming system.
Solution Approach 2:
The document identifier acts as an intermediary element that links multiple individual page files into a coherent group. By repeating this identifier across all pages of a document, the system creates a natural grouping mechanism without requiring complex management structures.

AI summary
According to an embodiment, an image processing apparatus includes: an image reading device and a controller. The controller assigns a variable character string to a file identifier for each page of image files generated by the image reading device, and repeatedly assigns the same character string to the file identifier for each number of unit pages. Further, the controller determines a file name of each of the image files by using the file identifier.
