Exploring the Advantages and Differences between OIS and EIS in Image Stabilization Technology

Image stabilization technology has become an essential feature in security surveillance cameras.

Two of the most common forms of image stabilization technology are Optical Image Stabilization (OIS) and Electronic Image Stabilization (EIS). OIS uses a physical mechanism to stabilize the camera lens, while EIS relies on software algorithms to stabilize the image.

Advantages of OIS

One of the main advantages of OIS is its ability to produce sharper images in low-light conditions. The physical mechanism of OIS compensates for the movement of the camera, resulting in less blur and better image quality. OIS also allows for slower shutter speeds, which can result in better exposure and more natural-looking photos.

Advantages of EIS

One of the main advantages of EIS is its ability to be implemented in smaller, more compact devices. EIS relies on software algorithms, which can be implemented in smartphones and other small devices without the need for additional hardware.

EIS also has the advantage of being able to correct for a wider range of movements. OIS is only able to compensate for movement in one direction, while EIS can correct for movement in multiple directions.

EIS cannot alleviate image blurring caused by jitter.

Differences between OIS and EIS

The main difference between OIS and EIS is the mechanism used to stabilize the image. OIS uses a physical mechanism, while EIS relies on software algorithms. OIS is generally more effective at reducing camera shake and producing sharper images in low-light conditions, while EIS is more versatile and can be implemented in smaller devices.

In security CCTV camera, optical image stabilization is generally used for long focal range zoom cameras, because long range zoom cameras are more likely to be affected by wind blowing and environmental jitter.Well designed OIS zoom camera will not significantly increase the dimensions.

Conclusion

In conclusion, both OIS and EIS have their advantages and differences in image stabilization technology. OIS is generally more effective in producing sharper images , while EIS is more common and can be used for various cameras. Cameras that support OIS usually also support EIS.By combining EIS and OIS, better stability enhancement effects can be achieved.
