Image Stabilization Filter Selection for Processing Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face inefficiencies in achieving high-accuracy image stabilization due to the need for extensive information storage and processing to account for various aberration changes caused by optical image stabilization, leading to increased processing time and decreased system efficiency.
Innovation Solution
An image processing apparatus that selects and uses filter information for image stabilization from a storage medium to create a correction filter, enabling simultaneous execution of multiple image stabilization processes, such as lens and imager stabilization, to correct captured images effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all filter information for various optical image stabilization types is stored and processed, then comprehensive image correction is achieved, but processing time increases and system efficiency decreases
Solution Approach 1:
The patent extracts only the necessary filter information corresponding to the actual optical image stabilization type being used from the storage medium, rather than reading all filter information. This selective extraction reduces processing time while maintaining correction accuracy for the specific stabilization method employed.
Solution Approach 2:
The patent segments the filter information storage and processing into distinct categories corresponding to different optical image stabilization types. By organizing filter information according to stabilization type and selectively accessing only the relevant segment, the system achieves efficient processing without compromising correction reliability.
2Reliability
If multiple image stabilization processes are executed simultaneously, then higher image stabilization effect is achieved, but information processing complexity increases
Solution Approach 1:
The patent implements dynamic selection and combination of filter information based on the actual optical image stabilization type detected. The system adaptively adjusts which filter information is read and applied, enabling flexible execution of single or multiple stabilization processes simultaneously without fixed complexity overhead.
