Solution Overview

Problem

Existing image processing systems require users to manually input folder paths, which is time-consuming, and struggle when the target character string is not in a specified area, necessitating area setting for each document.

Innovation Solution

An image processing apparatus with a character recognition unit that identifies characters in image data and a display unit that shows recognized characters, allowing users to select characters for the folder path, thereby reducing manual input and area setting requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users manually input folder paths character by character using a keyboard, then the folder path can be accurately specified, but it takes much time and reduces productivity

Engineering Contradiction:
Improvefolder path specification accuracyVSAvoidfolder path input speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system automatically performs character recognition on the scanned document and generates candidate character strings without requiring manual keyboard input. The apparatus serves itself by extracting text from the image data and presenting it as fold er name candidates, eliminating the need for users to manually type folder paths while maintaining accurate specification through the recognized characters.

Inventive Principle:
Principle #25Self-service

2Device complexity

If a fixed area is specified for character recognition, then the character recognition process is simplified, but it cannot handle documents where the target character string is not in the specified area

Engineering Contradiction:
Improvecharacter recognition process complexityVSAvoiddocument format flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the character recognition area based on the actual document content. Instead of using a fixed predetermined area, the apparatus automatically determines the appropriate recognition area by analyzing the scanned image, allowing it to adapt to different document formats and positions of target character strings while maintaining a relatively simple recognition process.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the character recognition area is set for each document, then accurate character recognition can be achieved, but it becomes necessary and troublesome to set an area for each document

Engineering Contradiction:
Improvecharacter recognition accuracyVSAvoidarea setting time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary character recognition on the entire scanned document to identify potential target character strings before final folder name selection. By automatically analyzing the document content in advance and extracting candidate characters, the apparatus eliminates the need for users to manually set recognition areas for each document while maintaining high recognition accuracy through the preliminary analysis step.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If automatic character recognition is performed on the entire document, then all character strings can be captured, but the processing time and computational resources increase

Engineering Contradiction:
Improvecharacter string detection completenessVSAvoidcharacter recognition processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system extracts only the relevant character strings from the scanned document that are suitable for use as folder names, rather than processing and presenting all characters. By applying extraction criteria to identify and isolate target character strings from the broader document content, the apparatus reduces processing time and computational resources while maintaining complete detection of applicable folder name candidates.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An image processing apparatus includes a character recognition unit configured to perform character recognition processing for recognizing one or more characters included in image data and acquiring character information, a display unit configured to display one or more characters indicated by the character information acquired by the character recognition unit, and a transmission unit configured to transmit the image data to a folder the name of which is a character selected by a user from among the one or more characters displayed by the display unit.
