Dual-Side Camera Stabilization for Alignment Disturbance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera stabilization arrangements do not equally compensate for all disturbing influences on camera alignment, and sometimes overcompensate, leading to suboptimal image stabilization.
Innovation Solution
A camera stabilization arrangement featuring a movable camera holder with an electric drive, motion sensors, and a control device that performs both holder-side and camera-side image stabilization, allowing for precise compensation of camera movements and alignment disturbances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holder-side image stabilization is performed using electric drive and motion sensors, then image stabilization is improved, but device complexity increases
Solution Approach 1:
The stabilization system is divided into two independent but coordinated components: holder-side stabilization (electromechanical compensation via electric drive and motion sensors) and camera-side stabilization (electronic compensation via image capturing device). This segmentation allows each component to handle specific aspects of stabilization, improving overall reliability while distributing complexity across separate modules rather than concentrating all functions in one complex system.
Solution Approach 2:
The control device acts as an intermediary that receives data from motion sensors, processes stabilization requirements, and coordinates both the electric drive (holder-side) and image capturing device (camera-side). This intermediary coordination enables the two stabilization mechanisms to work together harmoniously, achieving improved image stabilization while managing system complexity through centralized control logic.
2Reliability
If both holder-side and camera-side stabilization are coordinated, then image stabilization is improved, but control complexity increases
Solution Approach 1:
The system employs feedback mechanisms where motion sensors continuously monitor camera holder movements and provide real-time data to the control device. The control device processes this feedback and dynamically adjusts both the electric drive positioning and image capturing device parameters to compensate for detected movements. This coordinated feedback control enables effective dual-side stabilization while managing control complexity through systematic signal processing and responsive adjustment of both subsystems.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved image stabilization by enabling precise coordination of holder-side and camera-side stabilization, effectively addressing various disturbing influences and optimizing image quality.
Implementation Method 1
The respective motion sensor may have, for example, a static or dynamic acceleration sensor, in particular a multi-axis type of acceleration sensor
Implementation Method 2
An electric drive which can be controlled, is able to drive the camera holder—and thus the camera fastened to it—according to the degrees of freedom. For this purpose, the electric drive may comprise, for example, one or more electric motors
Implementation Method 3
The camera stabilization arrangement further comprises a control device configured to control the electric drive in response to the motion sensor signals generated by the motion sensor(s) in order to perform holder-side image stabilization, and to also control the image capturing device in response to the motion sensor signals in order to perform camera-side image stabilization
