HEIF File Structure Optimization for Thumbnail Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in efficiently reproducing HEIF files, particularly in high-speed display of thumbnail images, as existing methods do not optimize the arrangement of related images within the mdat box for rapid access and processing.
Innovation Solution
A file processing device and method that arranges related images, such as thumbnail images and metadata, at the top of the mdat box in HEIF files to facilitate quick access and reproduction, allowing for efficient generation and reading of HEIF files, thereby enabling high-speed display of thumbnail images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If related images are arranged in the top part of the mdat box in HEIF files, then the reproduction speed and thumbnail display performance are improved, but the file structure complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-arranging related images (such as thumbnail images and cover images) in the top part of the mdat box during file generation. This advance organization allows reproduction devices to access frequently used images immediately without searching through the entire file, thereby improving reproduction speed while maintaining a manageable file structure through systematic placement rules.
2Loss of time
If related images are arranged in the top part of the mdat box, then the thumbnail display time is reduced, but the file processing complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the arrangement strategy within the mdat box structure. Specifically, it places related images (thumbnails, cover images) in the top portion of the mdat box while other image data follows subsequent arrangements. This localized optimization allows rapid access to frequently accessed images without requiring complex processing of the entire file structure, thus reducing thumbnail display time while controlling overall processing complexity.
3Productivity
If related images are prioritized in the mdat box arrangement, then the reproduction efficiency is improved, but the file format compatibility challenges increase
Solution Approach 1:
The patent implements preliminary action by pre-organizing related images in the top part of the mdat box during file creation. This advance arrangement ensures that reproduction devices can efficiently access thumbnails and cover images without complex processing, improving reproduction efficiency. The systematic placement follows structured rules that maintain compatibility with existing HEIF file format specifications, thereby balancing efficiency improvement with format compatibility.

AI summary
The present technology relates to a file processing device, a file processing method, and a program that enable efficient reproduction of a HEIF file.A high efficiency image file format (HEIF) file in which a related image associated with an image in the HEIF file is arranged in a top part of an mdat box is generated. Additionally, a top part of such a HEIF file is read. The present technology can be applied to generation and reproduction of a HEIF file.
