Camera Module with Multi-Axis Rotation for Image Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image stabilization technologies in electronic devices, such as OIS optical image stabilization, are limited to movement in three directions (X, Y, and Z axes) and result in poor image quality due to inadequate stabilization.
Innovation Solution
A camera module design that allows rotation around non-coplanar or intersecting axes (Y and Z) with additional stabilization through rotation around a third axis (X), enhancing stabilization capabilities and image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only three-direction movement (X, Y, Z axes) is used for image stabilization, then the device structure remains simple, but the image stabilization effect is poor and image quality deteriorates
Solution Approach 1:
The patent introduces a fourth degree of freedom by adding rotation around the optical axis (X-axis), transforming the traditional three-direction stabilization system into a four-axis system. This dimensional expansion enables more comprehensive compensation for hand-shake movements, particularly addressing rotational shake that cannot be corrected by linear movement alone, thereby improving image stabilization effectiveness without excessively complicating the overall device structure.
2Manufacturing precision
If the camera module moves only in three directions, then the manufacturing process remains straightforward, but the precision of image stabilization is insufficient
Solution Approach 1:
The stabilization system is segmented into four independent rotation modules, each responsible for a specific axis (Y-axis, Z-axis, and X-axis with additional degrees of freedom). This segmentation allows each module to be optimized and manufactured separately, then assembled into the complete stabilization system. The modular approach maintains manufacturing feasibility while achieving high-precision multi-axis stabilization through coordinated operation of individual segments.
3Reliability
If traditional OIS technology with limited movement is used, then the device maintains compact size, but the shooting quality suffers due to inadequate stabilization
Solution Approach 1:
The patent implements a dynamic stabilization system where the camera module can actively rotate around multiple non-coplanar axes including the optical axis. This dynamic multi-axis rotation capability allows the system to adapt to various shooting scenarios and hand-shake patterns, providing versatile stabilization performance that maintains compact device dimensions while significantly improving shooting quality through enhanced movement range and flexibility.
