How Does Optical Image Stabilization Work?

Optical Image Stabilization (OIS) is a technology that has revolutionized the world of photography and CCTV surveillance.

Since 2021, optical image stabilization has gradually emerged in security monitoring, and has the tendency to replace the traditional non optical image stabilization lens.Because it enables the capture of sharp and clear images even in shaky conditions, making it an essential feature in modern cameras and CCTV cameras. But how does OIS work? In this article, we will explore the technology behind OIS with a lens-based system.

OIS is a system that compensates for camera shake by moving the lens elements in the opposite direction of the motion. It works by using a gyroscope and an accelerometer to detect the movement of the camera. The information from these sensors is then sent to a microcontroller, which calculates the amount and direction of the lens movement required to counteract the camera shake.

The lens-based system of OIS uses a group of elements in the lens that can move independently of the camera body.

The lens elements are mounted on small motors that can change their position in response to the movement detected by the sensors. The motors are controlled by the microcontroller, which adjusts their position to counteract the camera shake.

In a camera, OIS is typically implemented in the lens itself, as it is the most effective way to compensate for camera shake. However, in a CCTV camera, OIS can be implemented in the camera body or in the lens, depending on the design and application.

The lens-based system of OIS has several advantages over other types of stabilization systems. It is more effective in compensating for camera shake, as it can correct for both rotational and translational movements. It also allows for faster and more precise corrections, as the lens elements can move quickly and accurately in response to the movement detected by the sensors.

In conclusion, OIS is a technology that has greatly improved the quality of images captured by cameras and CCTV cameras. The lens-based system of OIS is an effective and efficient way to compensate for camera shake, allowing for sharp and clear images even in shaky conditions. With the increasing demand for high-quality imaging in various fields, OIS is expected to become even more important in the future.
