Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing collage image creation technologies do not allow for easy adjustment of image rotation, size, and position without manually affecting the balance of other images, making it cumbersome to create and recreate collage images, especially with multiple images.

Innovation Solution

A collage image creating program that uses a placement algorithm incorporating rotation angles, aspect ratios, and weights to determine and re-determine image arrangements, allowing for easy recreation of collage images by adjusting parameters such as image position, rotation, and size, using a centroidal voronoi tessellation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a placement algorithm including rotation angle is used to create collage images, then the ability to consider image rotation is improved, but the complexity of the algorithm increases

Engineering Contradiction:

Improveimage rotation capabilityVSAvoidalgorithm complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by incorporating rotation angles as additional parameters in the placement algorithm. The algorithm accepts rotation angles for each image as input parameters and uses these parameters to determine optimal placement positions, thereby enabling rotation capability while managing complexity through systematic parameter handling

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If manual adjustment of image positions and sizes is performed to maintain balance, then the precision of image arrangement is improved, but the time and effort required increases significantly

Engineering Contradiction:

Improveimage arrangement precisionVSAvoidadjustment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system applies self-service by automatically recalculating and adjusting the positions and sizes of all images in the collage when one image is modified. The placement algorithm autonomously maintains overall balance without requiring manual intervention, making the system adjust itself in response to user changes

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements feedback by continuously monitoring changes to individual images and automatically triggering recalculation of the entire collage layout. This feedback loop ensures that any modification to one image automatically prompts the system to adjust other images to maintain balance, eliminating manual adjustment needs

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the position or size of one image is changed, then the flexibility of image arrangement is improved, but the burden of adjusting other images increases

Engineering Contradiction:

Improvearrangement flexibilityVSAvoiduser burden

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system reduces user burden by automatically handling the adjustment of other images when one image is modified. The placement algorithm self-adjusts the positions and sizes of remaining images to maintain overall collage balance, eliminating the need for users to manually rebalance the entire composition

Inventive Principle:

Principle #25Self-service

4Productivity

If automatic layout is used to generate collage images, then the productivity of collage creation is improved, but the ability to consider rotation angles is lost

Engineering Contradiction:

Improvecollage creation efficiencyVSAvoidrotation angle consideration

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent extends automatic layout capabilities by incorporating rotation angles as additional parameters in the placement algorithm. The system maintains automated processing while accepting rotation angles for each image as input parameters, thereby preserving productivity while gaining rotational versatility

Inventive Principle:

Principle #35Parameter changes

AI summary

A collage image creating method includes a first step that creates a collage image by determining arrangements of the plurality of images according to a placement algorithm including a rotation angle of each image as a parameter; and a second step that recreates a collage image by re-executing the first step to at least one of a change due to an addition or deletion of an image which configure the collage image, a change in arrangement position of at least one image among images which are included in the collage image, a change in rotation angle of at least one image among images which are included in the collage image, and a change in arrangement size of at least one image among images which are included in the collage image.
