Image Processing System Preview Region Attribute Selection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional image processing systems for setting attribute information on scanned business forms face challenges in accurately selecting character regions for attribute setting, often leading to erroneous selections due to lack of clear visual cues during the click operation.

Innovation Solution

The system includes a display unit showing a setting window with a preview region and a text field, where hovering over a character region in the scanned image preliminarily displays the corresponding character string and fixes it upon clicking, providing visual cues like frames or color changes to ensure accurate selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional click operation is used to select character regions, then the operation is simple, but erroneous selection occurs due to lack of clear visual cues

Engineering Contradiction:

Improveselection accuracyVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by displaying the character string corresponding to the character region in the text field before the user clicks. This preliminary display of the character string provides clear visual feedback about which character region will be selected, allowing the user to confirm the selection before finalizing the click operation, thereby preventing erroneous selection while maintaining operational simplicity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by displaying the character string in the text field in response to the mouse-over event. This feedback mechanism shows the user what character region will be selected upon clicking, providing clear visual cues that enhance selection accuracy without adding complex operation steps

Inventive Principle:

Principle #23Feedback

2Measurement precision

If no visual feedback is provided during character region selection, then the interface is simple, but user accuracy in selecting character regions deteriorates

Engineering Contradiction:

Improvecharacter region selection precisionVSAvoidinterface complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses the text field as an intermediary element that displays the character string corresponding to the character region. This intermediary provides a clear visual representation of the selected character region, enhancing selection precision without requiring complex graphical indicators or additional interface elements

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system employs color changes or visual highlighting in the text field to indicate the character string corresponding to the moused-over character region. This visual feedback mechanism improves selection precision by providing clear color-coded information about the selected region while maintaining interface simplicity

Inventive Principle:

Principle #32Color changes

AI summary

In a system, a setting window including at least a preview region in which a scanned image is previewed and a text field to which attribute information on the scanned image is input is displayed, when a character region within the scanned image previewed in the setting window is moused over, control to preliminarily display a character string corresponding to the moused-over character region in the text field is performed, and when the moused-over character region is clicked by a mouse, control to fix the character string preliminarily displayed in the text field is performed.
