Scene-Aware Image Trimming for Photo Album Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing methods for creating photo albums often fail to automatically select and trim images in a way that suits the specific scene type, leading to user discomfort due to inappropriate positioning of face regions in the composition.
Innovation Solution
An image processing apparatus and method that determines the scene type of an image and adjusts the trimming region accordingly, using a scene determination unit, position determination unit, and trimming unit to ensure appropriate image trimming based on the scene type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If trimming is performed by centering the face region, then the face region is located at the center, but the user may feel discomfort depending on the type of scene
Solution Approach 1:
The patent applies local quality by determining different trimming positions based on scene types. Instead of using a single universal trimming rule (centering the face), the system adjusts the trimming position according to the specific characteristics of each scene type (e.g., portrait, landscape, street), making the trimming operation locally optimized for each scene context.
Solution Approach 2:
The patent changes the trimming position parameter based on scene type classification. The system automatically identifies the scene type and adjusts the trimming position parameter accordingly, transforming a fixed parameter approach into a dynamic one that adapts to different scene conditions.
2Ease of operation
If a fixed trimming position is used, then the operation is simple, but it does not suit all scene types
Solution Approach 1:
The system performs self-service by automatically determining the scene type and selecting the appropriate trimming position without requiring user intervention. The algorithm autonomously analyzes image characteristics, classifies the scene type, and adjusts the trimming position accordingly, making the operation simple for users while achieving adaptability through automated scene-aware processing.

AI summary
The position of a trimming region is decided in accordance with a scene type represented by an image which is a layout target. The trimming region is trimmed at the decided position.
