HEIF File Reserved Area for External Data Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High efficiency image file format (HEIF) files lack the ability to efficiently associate images stored within them with external data located outside the file.
Innovation Solution
A file processing device and method that secures a reserved area in HEIF files to store relationship information for associating images with external data, using specification information to link internal and external data within the file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If HEIF files use a compact format for efficient image storage, then storage efficiency is improved, but the ability to associate images with external data deteriorates
Solution Approach 1:
The HEIF file structure is segmented into distinct boxes, with a dedicated 'reserved for HEIF extension' box that can store association information. This segmentation allows the compact image data to remain efficient while providing a separate structured region for metadata and external data associations without increasing overall file complexity.
Solution Approach 2:
Association information and external data references are nested within the HEIF file structure as embedded boxes. The file contains nested hierarchical structures where metadata boxes can contain references to external files, creating a layered organization that maintains compactness while enabling complex associations between images and external data.
2Device complexity
If HEIF files store only internal image data, then file simplicity is improved, but data management flexibility deteriorates
Solution Approach 1:
The reserved box structure in HEIF files is designed with multi-functionality, capable of storing various types of information including association metadata, external data references, and extension data. This universal structure allows the same file format to handle both simple image storage and complex data management scenarios without requiring fundamentally different file structures.
Solution Approach 2:
The HEIF file structure pre-allocates reserved boxes and metadata regions during file creation, preparing the structure in advance to accommodate future association data and external references. This preliminary structuring enables flexible data management capabilities to be activated as needed without requiring complex file restructuring operations later.

AI summary
The present technology relates to a file processing device, a file processing method, and a program that enable association of, for example, an image stored in a file with external data outside the file.A file control unit generates a high efficiency image file format (HEIF) file in which a reserved area is secured that is used to store relationship information related to association of an image stored in the HEIF file with specification information specifying external data that is outside the HEIF file and is to be associated with the image. Furthermore, the file control unit writes the relationship information into the HEIF file by using the reserved area. The present technology can be applied to, for example, a case where a HEIF file is generated and an image stored in the HEIF file is associated with external data later, and the like.
