Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional imaging devices are used without special hardware like gyroscopes, then device complexity is reduced, but image quality deteriorates due to inability to accurately predict and correct motion blur
Solution Approach 1:
The patent replaces mechanical sensing systems (gyroscopes, accelerometers) with a computational approach using image processing algorithms. The motion estimation is achieved by comparing sequential image frames to detect motion vectors, substituting physical sensors with digital signal processing to maintain image quality while reducing hardware complexity
Solution Approach 2:
The patent creates virtual motion sensors by generating motion estimation data from image frame comparisons. Instead of using physical gyroscopic copies of motion, the system synthesizes motion information from visual data, allowing blur correction without the need for actual mechanical sensing hardware
2Manufacturing precision
If motion estimation is performed using multiple still images or dynamic images before actual imaging, then image quality is improved by preventing blur, but loss of time increases due to additional pre-imaging steps
Solution Approach 1:
The patent performs motion estimation using previously captured dynamic images or still images before the actual imaging moment. By analyzing motion trends from prior frames, the system prepares blur correction parameters in advance, allowing the actual image capture to proceed quickly with pre-computed correction data
Solution Approach 2:
The patent maintains continuous motion estimation by utilizing overlapping image sequences where previous frames serve as reference for current motion analysis. This continuous processing allows the system to track motion smoothly over time without requiring complete re-analysis for each image, reducing redundant computation time
