AP-OIS is an optical image stabilization solution based on actuator position control. It achieves real-time compensation for lens displacement by precisely controlling the movement of the lens module. This solution boasts advantages such as compact structure, fast response speed, and high control precision, effectively improving the stability of mobile devices during photo taking and video recording. SI AP-OIS solution combines high-precision position detection technology with intelligent control algorithms to achieve micron-level motion control and rapid shake correction, meeting the image stability requirements of high-pixel, multi-camera systems in smartphones and helping devices achieve clearer and more stable image performance.
