Optical Image Stabilization (OIS) is a widely used anti-shake technology in both digital cameras and smartphones. Despite its popularity, many still don't fully understand what OIS is and its advantages for cameras. In this article, we will explore optical image stabilization, its benefits, and discover some devices that support OIS.
What is Optical Image Stabilization (OIS) technology?
Optical Image Stabilization (OIS) is a technology that helps minimize image shake when taking photos or recording videos on mobile devices such as smartphones or cameras.
OIS technology works by using an accelerometer to detect device movement and adjusting the lens to keep the image stable. Through mechanical or electronic mechanisms, the OIS system moves the lens opposite to the device's motion, preventing blurry or fuzzy images.
Advantages of Optical Image Stabilization (OIS) technology
Optical Image Stabilization (OIS) technology brings many useful benefits to users when capturing photos or recording videos on mobile devices. Let's explore the outstanding advantages of OIS right below:
Stable Images
OIS helps minimize image shake, making images clearer and of better quality. This technology is integrated into many mobile devices today such as digital cameras, smartphones, and camcorders. It reduces image shake during photo or video capture, resulting in more stable and higher-quality images.
OIS reduces image shake, resulting in clearer and higher-quality imagesLow-Light Photography
In low-light conditions, a device with OIS Camera becomes even more essential. In low-light situations, the shutter speed needs to be slower to allow enough light, leading to prolonged exposure times and loss of image stability. With this technology, the lens will automatically move slightly to keep the image stable, increasing the speed of photography without sacrificing image stability.
More Authentic Photo and Video Capture
Devices supported by Optical Image Stabilization (OIS) technology also help minimize unwanted movements when taking photos or recording videos, making the images or videos more authentic and of higher quality. Particularly, with this technology, users can capture photos or videos handheld without the need for supporting devices like tripods or stabilizers.
How OIS Works
OIS operates by utilizing mechanical or electronic mechanisms to adjust the position of the lens or image sensor during photo or video capture.
When users take photos or record videos, sensors in the device measure the device's movements and vibrations. If any motion or vibration is detected, the lens or image sensor on the OIS Camera will be automatically adjusted to keep the image stable.
With mechanical mechanisms, OIS technology employs complex structures inside the lens to move or rotate the lens along different axes. When the device moves or vibrates, these mechanisms automatically adjust the lens to keep the image stable.
OIS operates using either mechanical or electronic mechanismsWith electronic mechanisms, OIS technology utilizes accelerometer sensors to measure the device's movements and vibrations. Subsequently, this information is sent to the processing and control unit, which then instructs electronic motors to move the image sensor or lens to keep the image stable.
Additionally, this technology can also integrate with other technologies such as laser sensors or image processing computers to further enhance image stability.
In summary, Optical Image Stabilization (OIS) technology operates by utilizing either mechanical or electronic mechanisms to adjust the position of the lens or image sensor during photo or video capture, helping to minimize image shake and enhance image stability.
Distinguishing Optical Image Stabilization from other stabilizing technologies
Different stabilizing technologies have different methods of operation, leading to various advantages and disadvantages. Below are specific ways to distinguish between different stabilizing technologies:
| Công nghệ | Chống rung quang học OIS | Chống rung điện tử EIS | Chống rung cơ học IBIS |
| Tính năng | Công nghệ này sử dụng một cảm biến gia tốc để đo chuyển động và rung động của thiết bị và sau đó điều chỉnh vị trí của ống kính hoặc cảm biến hình ảnh để giữ cho hình ảnh ổn định. OIS thường được sử dụng trên các thiết bị chụp ảnh và điện thoại thông minh cao cấp. Ưu điểm của OIS là độ chính xác cao, giúp giữ cho hình ảnh ổn định ngay cả khi di chuyển hoặc chụp ảnh trong môi trường khó. | Công nghệ này sử dụng cảm biến gia tốc để đo chuyển động và rung động của thiết bị và sau đó điều chỉnh hình ảnh bằng cách cắt hoặc thu nhỏ khung hình. EIS thường được sử dụng trên các điện thoại thông minh giá rẻ. Tuy nhiên, EIS không thể điều chỉnh được việc chuyển động hoặc rung động ở trục dọc. | Công nghệ này sử dụng các cơ cấu bên trong máy ảnh để di chuyển cảm biến hình ảnh theo các trục khác nhau để giữ cho hình ảnh ổn định. IBIS thường được sử dụng trên các máy ảnh chuyên nghiệp. Ưu điểm của IBIS là có thể điều chỉnh được việc chuyển động và rung động ở mọi trục. |
Smartphones with OIS Camera
Currently, many smartphone manufacturers have implemented Optical Image Stabilization (OIS) technology for the cameras of their products. Smartphones with OIS Camera include:

Samsung Galaxy S22 Ultra 5G 128GBiPhone 13 Pro Max 128GB
The iPhone 13 Pro Max 128GB is equipped with Optical Image Stabilization (OIS) technology. This is one of the highly rated features on Apple's premium phones, allowing users to capture photos and videos with high stability, especially in low-light conditions or when shooting from a distance. With OIS technology, the camera on the iPhone 13 Pro Max 128GB will automatically adjust to compensate for user hand shake, making the image sharper and not blurry or fuzzy.
Google Pixel 5, 4, 3
The Google Pixel 5, 4, 3 phones are all equipped with Optical Image Stabilization (OIS) technology on the main camera. OIS technology on these devices will make photo and video capture more stable, especially in low-light conditions or when shooting from a distance. According to Google, OIS technology on these models can adjust up to 3 different motion axes, minimizing shake and keeping the image sharp and accurate.
In summary, Optical Image Stabilization (OIS) is an important technology that addresses hand shake issues when using cameras or smartphones. This improves the quality of photos and videos, providing users with a better experience when taking photos or shooting videos.
