Camera Holder Stabilization Using Sensor-Based Motion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld camera devices often produce blurry or out-of-focus images due to user hand shaking, which existing solutions like gimbals or stabilizers address using motion sensors and electronic circuits, increasing manufacturing costs and product size.
Innovation Solution
A method and system that stabilizes a camera device by receiving sensor data on its orientation and movement, generating a control signal using a predetermined algorithm, and adjusting the geometrical behavior of the camera device holder to maintain a stable field-of-view, potentially integrating sensors within the device or holder.

Engineering Contradiction Analysis
1Reliability
If gimbal or stabilizer is used with motion sensors and electronic circuits, then camera stabilization is improved, but manufacturing cost and product size increase
Solution Approach 1:
The patent extracts only the essential stabilization function from complex gimbal systems. Instead of using multiple motion sensors and electronic circuits, the invention uses a single image sensor to detect camera movement and a processor to generate correction signals, thereby achieving stabilization while reducing device complexity and size.
Solution Approach 2:
The patent replaces the mechanical gimbal system with an electronic/image-processing-based stabilization system. By using image sensor data and computational algorithms to detect and correct camera movement, the invention eliminates the need for complex mechanical stabilizing structures,ไป่ reducing product size and manufacturing cost.

Instead of using multiple motion sensors and electronic circuits, the invention uses a single image sensor to detect camera movement and a processor to generate correction signals, thereby achieving stabilization while reducing device complexity and size.
Solution Approach 2:
The patent uses standard image sensors and processors that are already present in most modern devices, replacing expensive specialized motion sensors and gimbal components. This approach leverages readily available, cost-effective components to achieve the same stabilization function.
3Reliability
If multiple motion sensors and associated electronic circuits are used, then camera stabilization is improved, but device complexity increases
Solution Approach 1:
The patent merges the stabilization function with the existing image sensing and processing system. By using the image sensor for both image capture and movement detection, and the processor for both image processing and stabilization control, the invention eliminates the need for separate motion sensors and control circuits, thereby reducing component count while maintaining stabilization effectiveness.

AI summary
A method to stabilize a camera device. The method includes receiving, from the camera device mounted in a camera device holder, sensor data representing at least one selected from a group consisting of orientation and movement of the camera device, generating, using a pre-determined algorithm, a control signal based on the sensor data, and adjusting, using the control signal, a geometrical behavior of the camera device holder, wherein the geometrical behavior corresponds to at least one selected from a group consisting of the orientation and the movement of the camera device holder.
