Blur Correction Section State Transition Image Shift Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in smoothly transitioning from a mechanically retained state to an electrically retained state for blur correction without causing image shifts on the display, which can be uncomfortable for users.
Innovation Solution
The imaging apparatus includes a blur correction section that is mechanically retained at a predetermined position during non-performance and electronically retained during performance, with controlled display updates to prevent image shifts during state transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blur correction section is mechanically retained during non-performance and electronically retained during performance, then the reliability of blur correction is improved, but image shifts occur on the display during state transitions
Solution Approach 1:
The system performs preliminary actions by stopping image update operations and pausing OSD display before the mechanical-to-electronic state transition occurs. This prepares the display system in advance to avoid showing unstable images during the transition period, thereby maintaining image stability while enabling reliable blur correction functionality.
Solution Approach 2:
The system dynamically adjusts display operations based on the state transition timing. The image update operations and OSD display are temporarily suspended during the critical transition period from mechanical retention to electronic retention, and then resumed after stabilization. This dynamic control ensures that display content remains stable while the blur correction section transitions between operational states.
2Productivity
If the blur correction section transitions from mechanically retained state to electronically retained state, then the productivity of blur correction is improved, but image shifts occur during the transition
Solution Approach 1:
Before the blur correction section transitions to the electronically retained state for active correction, the system preliminarily stops image update operations and OSD display. This preliminary action prevents the display from showing unstable or shifting images during the transition, ensuring that when blur correction becomes productive and active, the display already shows stable images.
Solution Approach 2:
The display system dynamically responds to the state transition by suspending image updates and OSD display during the transition from mechanical to electronic retention. This dynamic adjustment allows the blur correction section to transition efficiently while maintaining image stability on the display, resolving the conflict between productivity improvement and image stability.
3Ease of operation
If the image update operation is stopped during state transition, then image stability is improved, but the loss of time occurs during the stoppage
Solution Approach 1:
The system applies the skipping principle by rapidly transitioning through the state change from mechanical to electronic retention while the display is paused. By stopping the display during the transition, the system rushes through the potentially problematic transition period quickly, minimizing the time impact. The display is then immediately resumed after stabilization, making the time loss negligible while ensuring image stability during the critical transition moment.
