Electronic Device Slow Motion Video Interval Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack the ability to automatically extract meaningful intervals from high-speed videos and provide them in slow motion, limiting user engagement and content analysis.
Innovation Solution
An electronic device equipped with a processor and memory that detects image variation in high-speed videos, generates slow motion intervals by dividing frames, and adjusts playback time, allowing for extended slow motion playback of selected intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed video capture is implemented, then the ability to record fast-moving events is improved, but the ability to automatically extract and analyze meaningful intervals is lost
Solution Approach 1:
The system automatically analyzes the captured high-speed video to identify intervals with significant image variation without requiring external intervention. The processor self-services by detecting motion events, determining their significance, and automatically generating slow-motion playback of selected intervals, eliminating the need for manual review of all captured frames.
Solution Approach 2:
The patent replaces manual mechanical review of video frames with automated computational analysis. The processor uses image variation detection algorithms to substitute for human operators who would otherwise need to manually examine each frame to identify meaningful intervals, enabling automatic extraction and selection of significant events.
2Loss of information
If all captured frames are played back, then complete content is provided, but user engagement and content analysis become difficult
Solution Approach 1:
The system extracts only the most significant intervals from the complete video content based on image variation analysis. By separating and highlighting intervals with substantial motion or changes from the rest of the video, the system enables users to focus on important events without being overwhelmed by redundant or insignificant frames, thus improving engagement while preserving access to complete content.
Solution Approach 2:
The patent applies different quality levels of analysis and presentation to different parts of the video. Significant intervals with high image variation receive enhanced treatment through slow-motion playback and prominent display, while less significant intervals are handled differently. This local differentiation of quality allows users to easily identify and engage with important content while maintaining access to the complete dataset.
3Duration of action of moving object
If frame division is used to create slow motion, then playback time extension is achieved, but processing complexity increases
Solution Approach 1:
The system applies frame division and slow-motion processing only to selected intervals that meet significance thresholds, rather than processing the entire video. By performing the complex frame division operation partially—only where and when needed based on image variation analysis—the system achieves playback time extension for meaningful events while avoiding the excessive processing complexity that would result from applying the same operations to all video content.

AI summary
An electronic device is provided. The electronic device includes a memory configured to store a high-speed video captured with a first number of frames per second and a processor configured to be electrically connected with the memory. The processor is configured to detect an amount of image variation based on at least one of the first number of frames and generate a slow motion interval, a playback time of which is extended, by dividing or sampling the first number of frames into a second number of frames which are less than the first number of frames with respect to a video interval having an amount of image variation which meets a specified condition.
