Solution Overview

Problem

Existing image file creation methods do not adequately generate accessory information related to base images used in composite image generation, particularly in terms of image generation modes and the preservation of thumbnail images during correction processing.

Innovation Solution

An image generation method that includes a reception step for selecting image generation modes and a generation step for creating accessory images based on base images, ensuring that thumbnail images are not altered by correction processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If accessory images are generated based on composite images, then the image file contains comprehensive information, but the accessory images may be incorrectly altered during correction processing

Engineering Contradiction:

Improveaccessory information completenessVSAvoidthumbnail image integrity

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent segments accessory information into two distinct types: accessory images generated from base images before composite image creation, and accessory images generated from the composite image itself. This segmentation allows different processing rules to apply to each type, preserving the integrity of base image thumbnails while maintaining comprehensive information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent generates accessory images from base images before the composite image is created, and stores them with identification information indicating they are based on base images. This preliminary action ensures these accessory images remain unchanged during subsequent correction processing of the composite image, preserving their original integrity.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If multiple accessory images are generated for different base images, then detailed information is preserved, but the image file size and processing complexity increase

Engineering Contradiction:

Improvebase image information detailVSAvoidimage file structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent creates a universal accessory image structure that can serve multiple functions: it can represent a single base image or multiple base images through identification information. This multi-functionality allows the system to handle both simple and complex scenarios with the same data structure, reducing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces identification information as an intermediary element that links accessory images to their source base images. This intermediary allows the system to manage multiple base images and their corresponding accessory images without creating a complex nested structure, simplifying the overall file organization.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If accessory images are updated to reflect composite image corrections, then consistency is improved, but the original base image information may be lost

Engineering Contradiction:

Improveimage consistencyVSAvoidoriginal base image data

Core Design Contradiction:

Stability of the object's compositionVSLoss of information

Solution Approach 1:

The patent generates and stores accessory images from base images before composite image creation, marking them with identification information. This preliminary action preserves the original base image information in a protected state that is not affected by subsequent corrections to the composite image.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies different quality characteristics to different accessory images: those generated from base images maintain their original quality and remain unchanged, while accessory images generated from the composite image reflect its corrected state. This local differentiation preserves original information where needed while maintaining consistency where appropriate.

Inventive Principle:

Principle #3Local quality
