Video File Segmentation for Static Image Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies face challenges in efficiently extracting and managing static images from videos, particularly in long recording times, where it is difficult to grasp the relationship between the video and the extracted static image.
Innovation Solution
An imaging device and method that captures video, generates static image files, divides video into multiple files based on static image extraction, and stores these files in association with the corresponding video files, allowing for easier retrieval and management of static images within the video context.

Engineering Contradiction Analysis
1Duration of action of moving object
If video recording time is extended to capture more content, then the quantity of captured scenes increases, but it becomes difficult to grasp the relationship between the video and extracted static images
Solution Approach 1:
The patent divides a long video into multiple segmented video files based on static image extraction points. Each segmented video file is associated with extracted static images through file name correspondence, making it easy to identify which static images belong to which video segment even when the total recording time is long.
Solution Approach 2:
The patent uses file name association as an intermediary mechanism to link static image files with their corresponding video files. By embedding static image file names within video file metadata or using consistent naming conventions, the system maintains the relationship information without requiring additional complex data structures.
2Quantity of substance
If static images are extracted from every frame of a long video, then the quantity of static images increases, but the processing load and storage requirements increase significantly
Solution Approach 1:
The patent extracts only specific key frames from the video as static images rather than processing every frame. The video is divided into segments, and static images are extracted at division points, reducing the total number of static images while maintaining representativeness.
Solution Approach 2:
The patent applies partial action by extracting static images only at critical division points between video segments rather than continuously throughout the entire video. This selective extraction reduces processing load while still providing sufficient static image coverage for the long video.
3Ease of operation
If video is divided into multiple files based on static image extraction, then the ease of retrieving specific static images improves, but the device complexity increases
Solution Approach 1:
The patent segments the video into multiple manageable video files based on static image extraction points. Each video file is paired with its corresponding static images through consistent file naming, creating a segmented but organized structure that simplifies retrieval operations.
Solution Approach 2:
The patent uses file name parameters as a simple metadata mechanism to associate static images with video segments. By changing only the file naming parameter rather than implementing complex database structures, the system achieves easy retrieval functionality with minimal added complexity.
