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

VSEngineering 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

Engineering Contradiction:
Improvevideo capture speedVSAvoidautomatic interval extraction
Core Design Contradiction:
SpeedVSExtent of automation

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If all captured frames are played back, then complete content is provided, but user engagement and content analysis become difficult

Engineering Contradiction:
Improvecontent completenessVSAvoiduser engagement
Core Design Contradiction:
Loss of informationVSEase of operation

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improveplayback timeVSAvoidframe processing complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

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.

Inventive Principle:
Principle #16Partial or excessive action

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.
