EIS, or Electronic Image Stabilization, is a technological advancement in the field of photography and video recording that aims to eliminate blurring and shaking in images or footage caused by hand movements. With the ever-increasing integration of cameras into smartphones, action cameras, and other portable devices, EIS has become a crucial feature in ensuring high-quality visuals for users. By utilizing various sensors and processing algorithms, EIS compensates for the unintentional motions of the camera and provides smoother and more stable results. In this article, we will delve into the details of EIS, exploring its functionality, advantages, and limitations, while also discussing its impact on modern photography and videography. Whether you are a photography enthusiast or simply curious about the technology behind better visual stability, learning about the effects of EIS will provide valuable insights into the future of digital imagery.
Today’s smartphones are equipped with a lot of anti-shake technology to help improve the image and video quality of the device. And today, let’s find out with Thptlaihoa.edu.vn what is EIS electronic anti-vibration!
What is anti-vibration?
Image Stabilization is the name of a technology that helps you take photos with less shake and when recording videos with more stability. This technology helps your device absorb small vibrations, so the resulting image will be more stable.
What is the principle of anti-vibration?
Imagine you are watching TV and suddenly it starts to shake back and forth. Then you will see the image on the TV is shaken, blurred. However, if you and the TV are rocking back and forth equally. You will then feel less blur, even have the same feeling of viewing the image as if you were standing still.
That’s the basic principle of anti-shake, you just need to replace your phone with a camera lens and the other TV is the object you need to capture or record, everything will be the same.
What is Electronic Stabilization EIS?
In the simplest terms, EIS (EIS – Electronic Image Stabilization) is that you use software to serve the anti-shake instead of having to equip with complicated and expensive hardware. The digital anti-shake system uses a gyroscope to sense movement. From there, the captured video or image will be calculated to reduce vibration. In this system, the sensor captures more images, especially at the edges afterwards, and then changes the image to suppress vibrations.
What are the benefits of EIS Electronic Stabilization?
- Electronic Stabilization EIS is very convenient, useful for small cameras because no additional hardware is required. The cameras can therefore be made very small. The calculation was then done by the image processing chips.
- Because it is software, it can be easily integrated into existing devices.
- However, the biggest drawback of this technology is that it cannot be as accurate as optical image stabilization.
What devices are equipped with EIS electronic stabilization?
The most famous for EIS electronic stabilization technology on smartphones must be mentioned Sony with its flagship Xperia Z series when producing quality that is not inferior or even better than OIS optical image stabilization.
In addition, Google has also made technology lovers “admiring” with the EIS electronic anti-shake capability on the Google Pixel 2 and Pixel 2 XL duo. As mentioned above, EIS electronic anti-vibration technology is quite easy to integrate, so many smartphones on the market today are equipped with this technology.

In conclusion, Electronic Image Stabilization (EIS) is a valuable technology that helps improve the quality of videos and images by reducing motion blur and shakiness caused by camera movement. By utilizing gyroscopes or accelerometers, EIS detects and compensates for unwanted camera movements during recording or capturing. This innovative feature has become a standard in modern smartphones, action cameras, and other handheld devices, enabling users to capture smoother and more professional-looking footage.
The implementation of EIS has several significant effects on the quality of videos and images. First and foremost, it reduces the blurring caused by hand movements, resulting in clearer and sharper visuals. This is particularly useful in low-light situations or when using telephoto lenses, where even the slightest shake can have a pronounced impact on image quality. Additionally, EIS helps to stabilize panning and tilting movements, allowing for smoother transitions and ensuring a better viewing experience for the audience.
Moreover, EIS plays a crucial role in enhancing the overall user experience. By reducing shakiness and motion blur, it enables more enjoyable and immersive video playback. Whether users are capturing their adventures, recording important moments, or creating professional content, the implementation of EIS ensures that the final output is of superior quality.
Despite its numerous advantages, it is important to note that EIS does have its limitations. The technology relies on software algorithms to compensate for camera movements, which may result in minor cropping or loss of image quality. Moreover, EIS is not effective in eliminating larger or abrupt movements that occur due to external factors such as strong winds or sudden impacts. Therefore, while EIS significantly minimizes shake and blurring, it should not be considered a substitute for physical stabilization methods, such as optical image stabilization (OIS) or using tripods.
In conclusion, EIS is a powerful and widely-used technology that enhances the quality of videos and images by reducing motion blur and shakiness. It allows users to capture smooth, professional-looking footage, especially in challenging conditions. The effects of EIS are evident in the improved image quality, enhanced user experience, and overall satisfaction of those who utilize this technology. As technological advancements continue to evolve, we can expect further improvements and refinements in EIS, catering to the ever-growing demand for better visual content.
