Animated GIF Processor Frame Disposal Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Animated GIFs require significant storage space due to their large data size, especially when multiple versions are needed for different platforms, and existing optimization methods can lead to memory overload during processing.
Innovation Solution
An optimized process that decodes and optimizes animated GIFs frame by frame, using disposal methods and transparency to reduce data size, with a system that processes two frames at a time to manage memory and apply optimal disposal techniques, such as setting the blue background as transparent and using the 'Revert to Background' method, thereby reducing file size and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the entire animated GIF is decoded into memory for optimization, then optimization can be performed on all frames, but memory overload occurs
Solution Approach 1:
The patent divides the animated GIF into individual frames and processes them sequentially rather than loading the entire animation into memory at once. The system decodes one frame at a time, performs optimization on that frame, and then moves to the next frame, thereby segmenting the processing task to avoid memory overload while maintaining optimization quality.
2Quantity of substance
If disposal methods and transparency are applied to reduce frame data size, then storage space is reduced, but processing complexity increases
Solution Approach 1:
The patent applies disposal methods and transparency settings during the encoding phase before the animated GIF is stored or transmitted. By pre-configuring these optimization parameters while the frame structure is being built, the system reduces the final data size without adding complexity to subsequent processing operations. The disposal method and transparency are baked into the frame data structure in advance.
3Adaptability or versatility
If multiple versions of animated GIFs are created for different platforms, then compatibility is improved, but storage requirements increase
Solution Approach 1:
The patent creates a single optimized animated GIF version that uses universal disposal methods and transparency settings compatible across multiple platforms. By applying platform-agnostic optimization techniques during the encoding process, the system achieves broad compatibility without needing to maintain separate versions for different devices, thereby reducing storage requirements while maintaining adaptability.

AI summary
Systems and techniques for a large scale online lossless animated GIF processor are described herein. In an example, a lossless animated GIF processor is adapted to receive an animated GIF image and decode a first and second frame of the animated GIF image, wherein the decoding identifies a disposal method for each frame. The lossless animated GIF processor may determine an optimized disposal method for the second frame based on transparency pixels in the second frame and an overlap estimation between the second frame and the first frame. The lossless animated GIF processor may encode the second frame with the optimized disposal method. The lossless animated GIF processor may be further adapted to identify pixels in an area of interest, designate pixels outside the area of interest as transparent, and encode the area of interest and the pixels designated as transparent for the second frame.
