Camera Composition Recommendation via 3D Scene Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-professionals face difficulties in selecting and applying appropriate photography composition guides, as existing technologies either focus on aesthetic quality evaluation or adaptive armature identification, which often fail in complex scenes or are limited to simple compositions.
Innovation Solution
A device and method that captures temporary images, reconstructs the scene, generates a subject map, estimates an armature, combines it with the focused image, and provides instructions to adjust the composition, allowing for automatic adjustment with user permission, using a camera, display, and processor to improve photography composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adaptive armature identification based on image analysis is used, then photography composition is improved, but the system fails when the scene is complex because it does not consider three dimensional scene representation
Solution Approach 1:
The patent transitions from two-dimensional image analysis to three-dimensional scene representation by capturing multiple temporary images from different angles and reconstructing the scene in 3D space. This allows the system to understand spatial relationships and identify appropriate armatures even in complex scenes where 2D analysis fails.
Solution Approach 2:
The system captures multiple temporary images before the final photograph is taken, using these preliminary images to reconstruct the scene and pre-identify the armature. This preliminary analysis enables the system to provide accurate composition guidance before the user takes the actual photo.
2Loss of information
If text suggestions are given to improve photography composition, then composition guidance is provided, but it is not clear for users how to translate the text suggestion into photography composition
Solution Approach 1:
The patent introduces visual armature overlays as an intermediary between the text suggestions and the user's understanding. Instead of directly presenting text, the system visualizes the recommended armature structure superimposed on the scene, making the abstract text guidance concrete and easily understandable.
Solution Approach 2:
The system uses visual highlighting and color coding to mark different elements of the armature structure on the displayed image. This visual differentiation helps users quickly identify and understand which parts of the image correspond to specific armature elements, making the composition guidance intuitive.
3Ease of operation
If arrow guidance is used to improve portrait composition, then users can improve portrait composition without understanding the armature, but the system is limited to simple armatures and compositions
Solution Approach 1:
The patent creates a universal armature identification system that can handle various types of compositions (portraits, landscapes, close-ups) and complex scenes. The same 3D scene reconstruction and armature estimation process works across different subject types and background complexities, making the system versatile.
Solution Approach 2:
The system dynamically adapts the armature overlay to match the detected subjects and scene complexity. The armature positions, orientations, and weights are automatically adjusted based on the analyzed scene, allowing the system to provide appropriate guidance for both simple and complex compositions.
