Solution Overview

Problem

Existing ledger sheet recognition techniques fail to efficiently extract item values from tabular images, particularly when the image does not include item names, and the process of setting extraction areas is complex.

Innovation Solution

An information processing system and method that displays a setting screen with an extraction guide for each extraction target item on a tabular image, allowing users to set the position of the extraction guide, facilitating the extraction of item values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing ledger sheet recognition techniques are used to extract item values from tabular images, then the extraction can be performed, but the process of setting extraction areas becomes complicated and inefficient

Engineering Contradiction:

Improveease of setting extraction areaVSAvoidcomplexity of extraction area setting

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The extraction area setting is divided into multiple extraction guides, each corresponding to a specific extraction target item. Each extraction guide can be independently positioned and adjusted, allowing users to set extraction areas for different items separately without affecting others. This segmentation simplifies the overall operation by breaking down a complex task into multiple manageable steps.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Extraction guides serve as intermediary elements between the user and the tabular image. These guides are displayed on the image and can be dragged to desired positions, acting as a mediator that translates user intentions into precise extraction area selections. The extraction guides simplify the interaction by providing visual references that can be easily manipulated.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If automatic extraction is attempted without user input, then the process is faster, but accuracy decreases when item names are not described in the image

Engineering Contradiction:

Improveaccuracy of item value extractionVSAvoidtime for extraction process

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system allows users to quickly set extraction areas by simply dragging extraction guides to the desired positions on the tabular image. This self-service approach enables users to perform the extraction area setting themselves without requiring complex manual procedures or multiple steps, thereby maintaining speed while ensuring accuracy through direct user input.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The extraction guides are pre-configured and displayed on the tabular image before the user needs to perform extraction. This preliminary preparation allows users to immediately begin setting extraction areas without needing to perform additional setup steps, reducing the overall time required while maintaining high accuracy through direct user control.

AI summary

An information processing system includes circuitry. The circuitry causes a terminal apparatus to display a setting screen for setting an extraction area for extracting, from a tabular image, an item value for each of one or more extraction target items. The setting screen displays, on the tabular image, an extraction guide representing the extraction area according to each of the one or more extraction target items. The circuitry further receives an operation of setting a position of the extraction guide on the setting screen.
