Quality-Based Image Frame Storage for Longer Capture History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face storage space issues when capturing and storing high-quality images in real-time, leading to earlier images being deleted, preventing users from viewing them.
Innovation Solution
An image frame storage method that selects and stores image frames based on quality criteria, including higher quality and content difference, optimizing storage capacity usage and prolonging the time span of stored images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the electronic device stores all shot images in real-time, then the storage quantity increases, but the storage space is quickly occupied and earlier images are deleted
Solution Approach 1:
The patent changes the storage parameter from storing all frames to storing only selected frames based on quality metrics and content difference thresholds, thereby extending the effective storage duration without increasing total storage consumption
Solution Approach 2:
The patent applies different quality standards to different image frames by evaluating each frame's quality metric and content difference, storing only those frames that meet the quality threshold, thus optimizing storage space utilization
2Manufacturing precision
If the electronic device stores high-quality image frames, then the image quality improves, but the storage space occupied increases
Solution Approach 1:
The patent introduces quality metric and content difference as selection parameters, storing only frames that meet the quality threshold and have sufficient content difference from previously stored frames, thereby maintaining high image quality while reducing storage space consumption
Solution Approach 2:
The patent discards redundant low-quality or similar frames and recovers storage space for storing new high-quality frames, achieving a balance between image quality and storage space utilization

AI summary
An image frame storage method is applied to an electronic device, where a maximum frame quantity of image frames that are allowed to be stored in a first storage space of the electronic device is N, where N is a positive integer. The method includes collecting a first image frame within first duration, where every m first image frames consecutively collected within the first duration are a group of image frames; and storing a second image frame that meets an image quality condition and that is in the first image frame into the first storage space.
