Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If calibration information is updated only by user operation, then device complexity is reduced, but image quality deteriorates when vibration occurs
Solution Approach 1:
The system continuously monitors vibration sensor data and automatically triggers calibration updates when vibration exceeds threshold values, creating a feedback loop that maintains image quality without requiring user intervention. The vibration detection unit feeds information to the control unit, which decides when calibration information should be updated based on actual vibration conditions.
Solution Approach 2:
The system performs self-calibration by automatically detecting vibration events and updating calibration information without requiring user operation. The control unit autonomously determines when calibration is needed and executes the update process, making the system self-sufficient in maintaining optimal calibration state.
2Manufacturing precision
If calibration information is updated frequently, then image quality is maintained, but loss of time increases
Solution Approach 1:
Instead of continuous calibration updates, the system performs calibration updates periodically based on vibration events. The control unit checks vibration sensor data at regular intervals and triggers calibration only when vibration thresholds are exceeded, avoiding unnecessary updates and saving time.
Solution Approach 2:
The system changes the calibration update frequency based on vibration parameter thresholds. When vibration exceeds predetermined thresholds, calibration updates are triggered; otherwise, the system maintains existing calibration information, dynamically adjusting update frequency based on actual conditions.
3Reliability
If vibration detection is implemented, then reliability of calibration is improved, but device complexity increases
Solution Approach 1:
The vibration sensor acts as an intermediary that indirectly detects optical axis displacement without requiring direct measurement of lens position. By monitoring vibration events that cause misalignment, the system infers calibration needs without complex direct measurement systems.

AI summary
An image processing apparatus is an image processing apparatus for calibrating an image capture apparatus that includes an optical system and an imaging sensor, the apparatus including: an obtaining unit configured to obtain an image captured by the image capture apparatus; a detection unit configured to detect whether vibration occurred in the image capture apparatus; and an updating unit configured to in a case where the detection unit detects that the vibration occurred, update calibration information to correct the image captured by the image capture apparatus based on the captured image obtained by the obtaining unit.
