Solution Overview

Problem

Existing image capturing technologies struggle to accurately identify and provide the most appropriate image frame from a series of frames in a video without user intervention, often resulting in unnecessary image storage and limited composition applicability.

Innovation Solution

An electronic apparatus utilizing an artificial intelligence model to analyze and identify the best image frame by determining the degree of matching between input frames and predetermined feature information, allowing for automatic selection and provision of the desired image frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If continuous photographing is performed for a specific time, then the user can select the most desired picture among photographed images, but a large number of unnecessary images remain in memory

Engineering Contradiction:
Improveuser's ability to select desired pictureVSAvoidnumber of images stored in memory
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential and meaningful images from the continuous photographing sequence using AI-based analysis. The system identifies and extracts key moments (such as smiles, eye contacts, or specific expressions) while automatically discarding redundant frames, thereby reducing memory storage requirements while maintaining user satisfaction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs automatic image selection and optimization without requiring user intervention. The AI algorithm autonomously analyzes photographed images, determines the most desirable frames based on predefined criteria (such as facial expressions, composition, or moment significance), and presents the optimized set to the user, eliminating the need for manual selection of numerous images.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If photographing is performed based on predetermined composition, then the picture can be taken at a specific moment, but a tripod installation is necessary and utility range is limited

Engineering Contradiction:
Improveaccuracy of capturing specific momentVSAvoidrange of applicable compositions
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static, predetermined composition rules to dynamic, adaptive composition detection. The AI system continuously analyzes incoming video frames in real-time, dynamically identifying moments that satisfy composition criteria (such as rule of thirds, golden ratio, or subject positioning) without requiring the camera to be fixed on a tripod. This enables handheld shooting while maintaining compositional accuracy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of composition detection from fixed, pre-programmed rules to flexible, learnable parameters through machine learning. The AI model can be trained on diverse composition examples and adapt to different shooting scenarios, enabling versatile application across various subjects and situations while maintaining precise moment capture.

Inventive Principle:
Principle #35Parameter changes

3Extent of automation

If AI system is used to select best image among plurality of images, then the most appropriate image can be provided automatically, but computation process requires optimization

Engineering Contradiction:
Improveautomatic image selectionVSAvoidcomputation speed
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The patent segments the image analysis process into multiple stages: first, a coarse filtering stage that quickly identifies frames containing potential key moments using simplified features; second, a detailed analysis stage that applies comprehensive AI evaluation only to the filtered subset of frames. This segmentation reduces the overall computational load while maintaining accurate automatic selection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial AI analysis to all frames (identifying basic features like presence of faces, expressions, or motion) and excessive/detailed analysis only to selected frames that show potential key moments. This approach balances automation extent with computation efficiency, providing automatic best image selection without requiring full-computation processing of every frame in the sequence.

Inventive Principle:
Principle #16Partial or excessive action
