Solution Overview

Problem

Existing information processing apparatuses struggle to correctly position written objects on inclined images or character strings, as they often become misaligned during scanning or document handling, leading to difficulties in displaying written inputs at appropriate positions.

Innovation Solution

An information processing apparatus with a reception unit for user input, a generation unit for creating written objects, a reference detection unit for identifying the image's reference direction, and a correction unit that aligns the written objects with the detected reference direction, ensuring accurate positioning on the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If image data is acquired through scanning or document handling, then the image can be displayed on the display unit, but the image or character string may become inclined and written objects cannot be positioned at appropriate locations

Engineering Contradiction:

Improvewritten input positioning accuracyVSAvoidimage inclination

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The reference detection unit performs preliminary detection of the reference direction from the image or character string arrangement before the user performs written input. This preliminary action establishes a correction basis that will be applied to the written object, ensuring that even though the image may be inclined, the written object can be accurately positioned relative to the image content.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The correction unit acts as an intermediary between the user's written input and the final displayed written object. It uses the detected reference direction as a mediator to calculate and apply the appropriate correction, transforming the user's input coordinates into corrected coordinates that account for the image inclination, thereby achieving accurate positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the image is displayed as scanned or conveyed, then the document can be processed, but the reading position moves in the sub-scanning direction causing inclined images

Engineering Contradiction:

Improvedocument processing efficiencyVSAvoidimage inclination

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary detection of the reference direction from the displayed image or character string arrangement before written input is performed. This preliminary action captures the inclination information caused by scanning or document conveyance, establishing a correction basis that will be applied to ensure accurate written object positioning despite the image inclination.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The correction unit serves as an intermediary that uses the detected reference direction to transform user input coordinates into corrected coordinates. It mediates between the inclined image display (result of scanning/conveyance) and the desired accurate written object positioning, applying the appropriate geometric transformation based on the reference direction.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If correction is applied in the scanning direction only, then the image can be corrected, but the written object is displayed at a position not related to the arrangement of the image or character string

Engineering Contradiction:

Improveimage correctionVSAvoidwritten object positioning accuracy

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The correction unit is designed to handle both image correction and written object positioning correction in a unified manner. Instead of treating these as separate functions, it applies the reference direction detection to both tasks, making the correction mechanism universal. This allows the system to correct both the image inclination and the written object positioning using the same reference framework.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The reference direction detected by the reference detection unit serves as a common mediator for both image correction and written object positioning. The correction unit uses this single reference to perform both corrections in a coordinated manner, ensuring that the written object is positioned accurately relative to the corrected image or character string arrangement.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processing apparatus capable of displaying an image on a predetermined display unit, includes: a reception unit that receives a written input on an image according to an operation of a user in a state where the image is displayed on the display unit; a generation unit that generates a written object according to the written input received by the reception unit; a reference detection unit that detects a reference direction of the image displayed on the display unit; a correction unit that corrects the written object on the basis of the reference direction detected by the reference detection unit; and a display control unit that displays the written object generated by the generation unit.
