Solution Overview
Problem
When capturing images with handheld electronic devices, camera shake leads to reduced image quality and a decrease in the viewing angle, as existing technologies struggle to effectively stabilize images while maintaining the original angle of view.
Innovation Solution
A camera module with a video stabilizer that uses dual image sensors and processing circuitry to generate synthetic image data, determining the need for stabilization based on distance data and performing image stabilization operations to minimize angle loss by rectifying and cropping image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image stabilization operation is performed to improve image quality, then image quality is improved, but viewing angle is reduced
Solution Approach 1:
The patent divides the image data into multiple regions based on distance information, applying image stabilization selectively to specific regions rather than the entire image. This segmentation allows stabilization to be applied where needed while preserving the original viewing angle in other regions.
Solution Approach 2:
The patent applies different processing qualities to different regions of the image based on distance data. Regions with objects at specific distances receive stabilization processing, while other regions maintain their original characteristics, creating local quality variations that resolve the contradiction between stabilization and viewing angle preservation.
2Reliability
If image stabilization is applied to the entire image, then image quality improves, but the loss in viewing angle increases
Solution Approach 1:
The patent applies image stabilization partially rather than excessively to the entire image. By using distance information to identify specific regions requiring stabilization, the system performs partial action only where necessary, avoiding the excessive application that would cause viewing angle loss while still achieving effective stabilization where needed.
