Sensor Shifting Module With Multi-Axis OIS for Dynamic Camera Shake

The patent replaces the traditional mechanical lens barrel driving system with an electromagnetic actuator system that directly drives the image sensor. This substitution reduces the driving force requirement because the image sensor is lighter than a lens barrel, while still achieving effective optical image stabilization through direct sensor movement.

Instead of moving the lens barrel to achieve stabilization, the patent inverts the approach by moving the image sensor in the opposite direction of camera shake. This inversion allows for more efficient stabilization with reduced force requirements since the sensor is much lighter than the lens assembly.

The patent extends the image sensor movement from two dimensions (orthogonal to optical axis) to three dimensions by adding rotational movement capabilities. The sensor can now move laterally and rotate about the optical axis, enabling correction of shaking in all directions including roll, pitch, and yaw, thus providing comprehensive stabilization in dynamic environments.

The patent implements a dynamic movement system where the image sensor can adaptively change its movement pattern based on the type and magnitude of shake detected. The actuator system provides continuous, multi-axis adjustment capabilities rather than fixed positional correction, enabling real-time adaptation to varying shooting conditions.
