Sprite JPEG Animated Thumbnail Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional formats for animated thumbnails, such as GIF and PNG, suffer from severe image quality degradation and compression inefficiency, making them unsuitable for true color images and high-entropy videos, and are unable to efficiently provide animated thumbnails in low network speed environments or simultaneously display multiple animated thumbnails.
Innovation Solution
The implementation of a sprite JPEG image, which concatenates video frames vertically and includes a custom header for animation playback information, allowing for efficient compression and display of animated thumbnails with enhanced image quality and smaller file size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional formats (GIF, PNG) are used for animated thumbnails, then animation effect is provided, but image quality degrades severely and compression efficiency is poor
Solution Approach 1:
The patent combines multiple video frames into a single sprite JPEG image by arranging them vertically, merging the animation functionality with the efficient JPEG compression format. This allows the system to enjoy both animation effects and high compression efficiency with maintained image quality
Solution Approach 2:
The patent changes the structural parameter of the thumbnail by organizing frames vertically in a sprite sheet format rather than using conventional GIF/PNG animation structures. This parameter change enables compatibility with JPEG compression while maintaining animation capabilities
2Productivity
If conventional animated formats are used, then animation is displayed, but file size is large and network transmission is inefficient
Solution Approach 1:
Multiple frames are merged into a single sprite JPEG image, reducing the number of separate files needed and improving network transmission efficiency. The single file structure eliminates overhead from multiple file transmissions while maintaining all animation frames
Solution Approach 2:
The patent changes the file structure parameter from multiple separate animation files to a single consolidated sprite JPEG file, significantly improving network transmission efficiency and reducing total file size while maintaining animation quality
3Adaptability or versatility
If conventional animated thumbnail formats are used, then animation effect is provided, but multiple thumbnails cannot be displayed simultaneously
Solution Approach 1:
Multiple video frames are merged into a single sprite JPEG image that can be efficiently transmitted and displayed. This single-file structure enables simultaneous display of multiple thumbnails without requiring complex coordination of multiple animation files
Solution Approach 2:
The patent organizes frames in a vertical dimension within the sprite sheet, allowing the system to efficiently manage and display multiple frames and multiple thumbnails simultaneously by utilizing the vertical arrangement space rather than requiring horizontal expansion or additional files
4Speed
If conventional animated formats are used, then animation is provided, but performance is poor in low network speed environments
Solution Approach 1:
The patent changes the file format parameter to sprite JPEG, which provides superior compression compared to conventional animated formats. This parameter change enables faster loading speeds in low network environments while maintaining animation quality and reducing bandwidth consumption

AI summary
Disclosed is a method, system, and non-transitory computer-readable record medium for providing an animation function using a sprite joint photographic experts group (JPEG) image. An animated image providing method includes creating, by processing circuitry, a sprite joint photographic experts group (JPEG) image from a video in an animated format, and providing, by the processing circuitry, an animated thumbnail of the video based on the sprite JPEG image.
