Tilt OIS Camera Rotation for Image Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handshake-induced camera instability leads to blurry photographs and wobbly videos, as existing technologies fail to effectively stabilize the camera during image capture and video recording.
Innovation Solution
An electronic device equipped with a tilt Optical Image Stabilizer (OIS) that rotates the camera about at least one axis, coupled with a processor to operate the camera and OIS for image capture and synthesis, allowing for shake compensation and expanded viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is held manually during photographing, then the operation is simple and portable, but hand shake causes image displacement and blurriness
Solution Approach 1:
The patent introduces an optical image stabilizer as an intermediary component between the camera and the user's hand. This stabilizer includes a floating lens assembly that can independently move to compensate for hand shake, acting as a mediator that isolates the camera sensor from hand movements while maintaining simple manual operation
Solution Approach 2:
The optical image stabilizer uses a counterbalancing mechanism where the floating lens assembly moves in the opposite direction to hand shake movements. This counter-movement compensates for the displacement, effectively canceling out the harmful effects of hand shake and maintaining image stability
2Device complexity
If a fixed camera angle is used, then the device structure is simple, but the viewing angle is limited
Solution Approach 1:
The patent transforms the static camera structure into a dynamic one by introducing a rotatable camera module. The camera can rotate about a tilt axis under controller command, allowing the viewing angle to be adjusted dynamically while maintaining a relatively simple overall device structure
Solution Approach 2:
The patent adds rotational freedom in the tilt dimension to the camera module. This allows the camera to capture images at different angles by rotating about the tilt axis, effectively expanding the viewing angle capability without significantly increasing device complexity
3Manufacturing precision
If multiple images are captured and synthesized, then the viewing angle can be expanded and quality improved, but the processing time and complexity increase
Solution Approach 1:
The patent replaces complex mechanical multi-camera systems with a single camera that captures multiple images at different angles by rotation. The controller manages the rotation and coordinates the image capture and synthesis, substituting mechanical complexity with controlled operational complexity
