Shake Correction Lens and Rotating Imaging Device for Multi-Axis Stabilization

The patent replaces the electronic shake correction method with a mechanical shake correction system. Specifically, it uses a shake correction lens that can physically move in response to detected shake, driven by actuators (voice coil motors or ultrasonic motors) that convert electrical signals to mechanical displacement. This mechanical approach directly counteracts the shake at the optical level rather than through post-processing, thereby eliminating afterimages while maintaining image quality correction

The patent introduces a shake correction lens as an intermediary element between the imaging lens and the imaging device. This intermediate lens serves as a mechanical mediator that physically shifts to compensate for shake, bridging the gap between shake detection and image stabilization without relying on electronic post-processing that causes afterimages

The patent designs the shake correction lens to serve multiple functions: it acts as both an optical element for image formation and a movable shake correction element. The same lens structure is used for both imaging and stabilization purposes, eliminating the need for separate correction optics and reducing overall device complexity while maintaining effective shake correction performance

The patent merges the shake correction function with the existing lens structure by making the shake correction lens a component of the imaging lens assembly. The actuators are integrated into the lens barrel, and the control system combines shake detection and lens driving functions. This consolidation reduces the number of separate components and simplifies the overall device architecture while achieving effective multi-axis shake correction
