Image Stabilization via Object Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera devices face challenges in distinguishing between camera shake and subject movement, leading to unnecessary corrections and image distortion, as they cannot accurately differentiate between the two types of movement.
Innovation Solution
A method is provided where an electronic device selects a partial area of an image based on object sizes, movements, or positions, stabilizes the image accordingly, and optionally changes the partial area based on movement detection to improve image stabilization and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera device performs correction based on movement detection, then image stabilization is improved, but image distortion occurs due to inability to distinguish between camera shake and subject movement
Solution Approach 1:
The patent segments the image into multiple regions of interest (ROIs) based on object detection and tracking. By dividing the image into distinct areas corresponding to different objects, the system can independently analyze movement characteristics of each region, enabling differentiation between camera shake and subject movement without applying uniform correction across the entire image, thus avoiding distortion while improving stabilization accuracy
Solution Approach 2:
The patent applies different correction strategies to different regions of the image based on their movement characteristics. By analyzing the movement vectors and patterns in each ROI, the system determines whether each region corresponds to camera shake or subject movement, and applies appropriate correction only where needed, thereby maintaining image quality while improving overall stabilization reliability
2Productivity
If the camera device corrects movement without distinguishing between camera shake and subject movement, then correction coverage is increased, but unnecessary correction causes distortion
Solution Approach 1:
The patent dynamically adjusts the correction process based on real-time movement analysis. The system continuously monitors movement vectors and ROI characteristics to determine whether correction should be applied to each region, allowing flexible and adaptive correction coverage that responds to changing scene conditions, thereby avoiding unnecessary correction while maintaining comprehensive stabilization where needed
