Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If blur removal is performed by detecting blur in the imaged image and image-processing the detected blur, then blur can be removed from the image, but high calculation complexity is required which lowers data processing rate and reduces usability
Solution Approach 1:
The patent applies preliminary action by detecting motion during the exposure period before the image is fully captured. The motion detector continuously monitors motion parameters, and when motion exceeds a threshold, the controller interrupts exposure or adjusts readout timing. This prevents blur from occurring in the first place, rather than attempting to remove it through complex post-processing calculations.
Solution Approach 2:
The patent replaces the mechanical/computational approach of post-capture blur removal with a sensor-based motion detection system. By using motion detectors to sense physical motion parameters during exposure and using this information to control the imaging process in real-time, the system substitutes complex image processing algorithms with simpler motion-based control mechanisms.
2Manufacturing precision
If motion detection and control is implemented to prevent blur during exposure, then image quality is improved, but device complexity increases due to additional motion sensors and control mechanisms
Solution Approach 1:
The patent uses motion data as an intermediary between the physical motion of the camera and the imaging process. The motion detector captures motion parameters, which serve as intermediate information that the controller uses to adjust exposure timing and readout operations. This intermediary approach allows the system to respond to motion without requiring direct mechanical intervention or complex control algorithms.
Solution Approach 2:
The patent changes operational parameters of the imaging system based on detected motion parameters. When motion exceeds a threshold, the controller modifies exposure time, readout timing, or other imaging parameters to compensate for the motion. This dynamic parameter adjustment allows the system to maintain image quality while using relatively simple motion detection and control mechanisms.
