Solution Overview

Problem

The transition from webtoons to published comics format requires significant time and effort due to the differing arrangements of image cuts, with webtoons having flexible page ratios and published comics having fixed ratios.

Innovation Solution

A method and apparatus that extracts elements from webtoon content, reconstructs them into layers, and rearranges these layers into a designated format suitable for published comics, allowing for two-dimensional arrangement on pages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If webtoon content is manually converted to published comics format, then the conversion accuracy and layout quality improve, but the time and effort required increase significantly

Engineering Contradiction:
Improveconversion accuracyVSAvoidconversion time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical operations (cutting, pasting, arranging image cuts) with an automated image processing system that uses algorithms to detect boundaries, extract elements, and rearrange content. The system substitutes human labor with computational processes including boundary detection, element extraction, layer reconstruction, and automatic layout generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables the webtoon content to be automatically converted without requiring manual intervention at each step. The image processing apparatus performs self-service by automatically detecting image cut boundaries, extracting elements, reconstructing layers, and generating published comics layout based on the input webtoon image, thereby serving the conversion task autonomously.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If webtoon content is converted to published comics format, then the content adapts to fixed page ratios and two-dimensional arrangement, but the complexity of the conversion process increases

Engineering Contradiction:
Improveformat adaptabilityVSAvoidconversion process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the webtoon content into discrete image cuts based on boundary detection, then further segments each image cut into extractable elements. This segmentation allows the system to process and rearrange individual components independently, facilitating the transition from vertical webtoon layout to two-dimensional published comics format while managing complexity through modular processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions the content from the one-dimensional vertical arrangement characteristic of webtoons to a two-dimensional layout suitable for published comics. The image processing apparatus achieves this by extracting elements and rearranging them in a multi-dimensional space with defined page ratios, thereby adapting the content to the target format's spatial requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If image cuts are extracted and rearranged automatically, then productivity improves, but the precision of element extraction and layer reconstruction may deteriorate

Engineering Contradiction:
Improveconversion efficiencyVSAvoidelement extraction precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system incorporates feedback mechanisms in the form of layer masks that provide information about the structure and boundaries of extracted elements. The layer reconstruction process uses this feedback to adjust and refine the placement of extracted elements, ensuring that automatic processing maintains high precision in element extraction and layer reconstruction while achieving improved productivity.

Inventive Principle:
Principle #23Feedback
