Solution Overview
Problem
Current camera systems face challenges in miniaturization and stabilization, particularly in outdoor environments, due to limitations in mechanical correction systems that fail to compensate for complete rotations and large tilts, leading to image blurriness and poor quality.
Innovation Solution
A compact system structure for image recording, stabilization, and correction with an optical observation device that includes a displaceable image-recording unit mounted without play under mechanical preload, allowing continuous adjustment of the back focus and enabling precise axial positioning and rotation of the image-recording unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital correction systems are used to stabilize camera shake, then image processing can be performed internally, but the output resolution is limited due to severe cropping
Solution Approach 1:
The system divides the correction function into two independent parts: a mechanical correction unit that physically stabilizes the camera before image capture, and a digital processing unit that handles post-processing. This segmentation allows the mechanical system to preserve the full sensor area for high-resolution output while the digital system handles stabilization processing without cropping constraints.
2Manufacturing precision
If mechanical correction systems are used to compensate for camera shake, then the entire image sensor surface can be utilized, but the system cannot be sufficiently miniaturized
Solution Approach 1:
The mechanical correction system is integrated within the camera housing structure, with the image-recording unit nested within a compact mechanical assembly. The correction mechanism uses a space-efficient design where moving components are arranged in a nested configuration, allowing the mechanical stabilization system to be miniaturized while still utilizing the full image sensor surface area.
3Adaptability or versatility
If Steady-Cam systems are used to compensate for large tilts and rotations, then complete rotations can be stabilized, but the systems are very large and inadequately protected against external influences
Solution Approach 1:
The mechanical correction system is enclosed in a compact, protected housing that shields internal components from external influences such as vibrations and shocks. The design uses a space-efficient configuration where the image-recording unit can perform complete rotations and large tilts while being adequately protected, reducing the overall system size compared to traditional Steady-Cam systems.
