Imaging Device Optical Correction Reset Subject Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face image shake issues during reset operations due to optical correction system movements, which change the angle of view and cause unintended subject position changes in captured images.
Innovation Solution
An imaging device with a camera shake detection unit, optical correction unit, reset determination unit, and electronic correction unit that optically corrects camera shake and electronically adjusts the image to counteract the subject position changes caused by reset operations, ensuring the optical correction system returns to its centering position and stabilizes the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical correction system performs a reset operation to return to the centering position, then the optical correction system can continue correcting camera shake within its correction range, but the angle of view changes and causes unintended subject position changes (image shake) in the captured image
Solution Approach 1:
The electronic correction unit performs preliminary anti-action by detecting the reset operation of the optical correction system and applying an opposite correction to the captured image. This electronic correction counteracts the angle of view change caused by the reset operation, preventing the intended subject position changes before they manifest as visible image shake in the final output.
Solution Approach 2:
The electronic correction unit acts as an intermediary between the optical correction system and the final image output. It receives the captured image data and the reset operation signal, processes them together, and generates a corrected image that compensates for the angle of view changes. This intermediary processing layer reconciles the mechanical reset operation with visual stability.
2Reliability
If the optical correction system continuously moves to track camera shake, then camera shake is corrected, but the system reaches the limit of the optical correction range and requires reset operations
Solution Approach 1:
The system implements feedback by continuously monitoring the position of the optical correction system and detecting when a reset operation is performed. The reset detection unit receives feedback signals from the optical correction system, and this feedback triggers the electronic correction unit to apply appropriate compensation. This closed-loop feedback mechanism automates the coordination between optical correction and electronic compensation.
Solution Approach 2:
The patent merges optical correction and electronic correction into a unified camera shake correction system. The optical correction system handles large-angle corrections by moving lenses or sensors, while the electronic correction unit handles the angle of view changes through image processing. By combining these two correction methods, the system achieves continuous correction without interruption from reset operations.
3Reliability
If the optical correction system is used to correct camera shake, then image stability is improved, but during reset operations the subject position changes unintentionally reducing image quality
Solution Approach 1:
The electronic correction unit applies preliminary anti-action by pre-calculating and applying the opposite of the angle of view change that will result from the reset operation. This ensures that when the optical correction system resets, the electronic correction has already compensated for the expected subject position changes, maintaining both image stability and subject positioning accuracy throughout the reset operation.
