Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical correction is used to correct image shake during exposure, then shake correction performance is improved, but power consumption increases and mechanical lifetime decreases
Solution Approach 1:
The patent implements dynamic switching between mechanical and electronic correction modes based on exposure time period. The control unit determines whether to use mechanical correction (moving correction lens or imaging element) or electronic correction (image processing) by comparing the exposure time period against a threshold, thereby optimizing power consumption while maintaining correction performance when needed
Solution Approach 2:
The system changes the operational parameters of the correction system based on exposure conditions. By adjusting the correction mode (mechanical vs electronic) according to the exposure time period parameter, the system achieves optimal balance between correction effectiveness and power efficiency
2Use of energy by moving object
If switching between mechanical and electronic correction is performed based on exposure time threshold, then power consumption is optimized, but image shake increases due to correction discontinuity
Solution Approach 1:
The patent applies preliminary action by performing preparatory movements of the correction lens or imaging element before the actual exposure begins. The control unit calculates the correction amount based on shake detection and positions the mechanical correction element in advance, ensuring seamless transition between correction modes without visible shake artifacts
Solution Approach 2:
The system uses an intermediary approach by combining both mechanical and electronic correction systems. During mode transitions, the electronic correction system acts as a bridge to maintain correction continuity while the mechanical system adjusts, preventing abrupt changes that would cause visible shake
3Reliability
If mechanical correction elements are frequently moved for shake correction, then correction performance is maintained, but mechanical lifetime decreases due to deterioration
Solution Approach 1:
The patent replaces mechanical correction with electronic correction under specific conditions (when exposure time period exceeds the threshold). By substituting the mechanical moving system with an electronic image processing system, the patent reduces mechanical wear and extends the lifetime of correction lenses and imaging elements while maintaining adequate correction performance

AI summary
A shake correction control device includes a processor that selects mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image. The processor performs a switching control from either of the mechanical correction or the electronic correction to the other of the mechanical correction or the electronic correction, and synchronizes shake correction operations of the mechanical correction and the electronic correction during the switching control, and changes an operation ratio of the mechanical correction and the electrical correction during the switching control.
