Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging apparatuses face challenges in achieving both effective image blur correction and low power consumption, as existing solutions either consume excessive power or suffer from optical axis misalignment due to mechanical locking mechanisms.
Innovation Solution
The apparatus includes a control unit that adjusts the position of movable units within the image blur correction system to cancel optical axis shifts caused by fixation, using a combination of mechanical locking and electrical communication between the camera and interchangeable lens to optimize power usage and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the deselected image blur correction apparatus is electromagnetically locked, then the apparatus maintains precise positioning capability, but power consumption increases
Solution Approach 1:
The system dynamically switches between electromagnetic locking (for precision) and mechanical locking (for power saving) based on operational requirements. The control unit determines when to use each locking method, making the locking mechanism adaptive rather than static.
Solution Approach 2:
The patent replaces electromagnetic locking with mechanical locking for the deselected image blur correction apparatus. This substitution eliminates continuous power consumption while maintaining positioning capability through purely mechanical means.
2Use of energy by moving object
If the deselected image blur correction apparatus is mechanically locked, then power consumption is reduced, but optical axis misalignment occurs due to nonuniformity in part dimension and urging force
Solution Approach 1:
The control unit monitors the state of both image blur correction apparatuses and detects optical axis shifts. When misalignment is detected due to mechanical locking, the control unit activates the other apparatus to compensate and restore proper optical axis alignment.
Solution Approach 2:
The system proactively compensates for potential optical axis misalignment by having a standby image blur correction apparatus ready to correct shifts. This preliminary arrangement prevents the need for complex adjustment mechanisms in the mechanically locked apparatus.
3Reliability
If both image blur correction apparatuses are continuously operated, then optimal image stabilization is achieved, but power consumption increases
Solution Approach 1:
The image blur correction function is divided into two separate apparatuses: one primarily operated and one standby. This segmentation allows the system to achieve optimal stabilization when needed while consuming less power during normal operation by keeping one apparatus in a low-power mechanical locked state.
Solution Approach 2:
The system changes the operational state of the image blur correction apparatuses based on conditions such as battery level and focal length. When power is abundant, both may operate for optimal performance; when power is limited, one is mechanically locked to save energy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables both efficient image stabilization and reduced power consumption by selectively enabling or disabling image blur correction units based on focal length and battery level, while maintaining optical axis alignment, thereby extending imaging time and improving camera performance.
Implementation Method 1
a movable unit 104a and a lock mechanism 150. The lock mechanism 150 is configured to move the movable unit 104a in a locking direction against an urging force of an elastic member 500a to 500c, thereby locking a position of the movable unit 104a
Implementation Method 2
move the position of the other of the first movable unit and the second movable unit in a direction that cancels a shift of an optical axis caused by the fixation of the one of the first movable unit and the second movable unit

AI summary
An apparatus includes a first correction unit including a first movable unit and a first mechanism configured to lock a position of the first movable unit. An interchangeable lens including a second correction unit is attachable to and detachable from the apparatus, and the second correction unit includes a second movable unit and a second mechanism configured to lock a position of the second movable unit. The apparatus further includes a control unit configured to, when the interchangeable lens is attached to the apparatus and one of the first and second movable units is fixed by the first or second mechanism, move the position of the other movable unit in a direction that cancels a shift of an optical axis caused by the fixation of the one of the first and second movable units.
