Image File Conversion for Metadata Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image file formats do not adequately support the addition of various types of additional information, such as object-related and rights-related data, which limits their utility in applications like machine learning and data management.
Innovation Solution
An image file conversion method and device that assess the current file format's capability to add additional information and convert it to a format that supports such additions, ensuring compatibility and expandability for object information, rights information, and other metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image file uses an existing standard format, then compatibility and ease of operation are improved, but the ability to add diverse additional information (object-related and rights-related metadata) deteriorates
Solution Approach 1:
The patent segments the file format into distinct components: a standard image data portion and a separate additional information portion. This segmentation allows the image file to maintain compatibility with standard formats while incorporating custom metadata fields for object-related and rights-related information without disrupting the overall file structure.
Solution Approach 2:
The patent implements a nested structure where additional information fields are embedded within the standard file format framework. The additional information portion is nested within the file structure, allowing standard format compliance at the outer level while providing space for custom metadata at the inner level.
2Adaptability or versatility
If the image file format is converted to support additional information, then adaptability and information completeness are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent performs preliminary actions by pre-defining the structure and format of additional information fields before actual data insertion. The file format is designed in advance with designated areas for object-related and rights-related metadata, so that when conversion is needed, the process follows a predetermined template rather than requiring complex real-time structuring.
Solution Approach 2:
The patent changes specific parameters of the file format, such as adding metadata fields, adjusting data structures, and modifying file headers, while maintaining core format parameters unchanged. This selective parameter modification allows adaptation to support additional information without completely redesigning the file format.
3Loss of information
If comprehensive additional information is added to image files, then information completeness and utility for machine learning are improved, but data management complexity and processing time increase
Solution Approach 1:
The patent extracts additional information into a separate, dedicated portion of the file structure, distinct from the core image data. This extraction allows the image data and metadata to be processed independently, enabling selective reading of only necessary information during machine learning operations, thereby reducing processing time while maintaining information completeness.
Solution Approach 2:
The patent implements partial action by allowing selective addition and processing of additional information fields. Not all metadata fields need to be populated or processed for every image file - only those relevant to the specific application (e.g., object recognition fields for ML training, rights fields for licensing) are actively used, reducing overall processing overhead.

AI summary
Provided are an image file conversion method, an image file conversion device, and a program that manage a format of an image file such that various types of additional information can be added.An image file conversion method includes an acquisition step of acquiring a first image file including image data in which an object has been recorded, a determination step of determining whether or not a first format, which is a file format of the first image file, satisfies a condition in which additional information including information related to the object or information of a right related to the first image file is capable of being added, and a conversion step of converting the first image file into a second image file whose file format is a second format, in which the additional information is capable of being added, in a case where the first format does not satisfy the condition.
