2 WHAT IS EIS?

CONTENT SUMMARY

We will describe OIS and EIS technologies in this article. We try answer questions that What is the differences of OIS and EIS and How to make a steady video? We share some platform where you can find out if the phone has OIS feature.

Not so much, five years ago, drones were not that common. Expensive jimijips and helicopters were in use. Likewise, the gimbals were not so small that they could fit into the palm. Special body equipment was produced to carry heavy cameras. In fact, many cameramen who carried these heavy equipment and video devices running in order to provide a smooth and clear image to the audience during football matches had serious health problems.

OIS is a lens feature, not a camera.

The growth of technology in the media has changed many things in the industry, especially broadcasting. While television used to feed at least the internet media and online streaming platforms, today the internet has become self-feeding. Of course, this was possible with the increase in personal publishing.

Personal broadcasting has caught the expected momentum with the developments in audio and video recording devices. Today, although it was not as creative as it was in its early days, it literally revolutionized. So what were the developments that provided this momentum?

First of all, both the welfare level in the world has gradually increased and technological products have become increasingly cheaper with new initiatives and discoveries. Action cameras, the size of a finger, were produced that put stones on film cameras during the day. Lightweight gimbals that can be held with one hand where we can put these cameras were launched. Phone cameras have evolved to make movies.

Finally, OIS and EIS technologies, which solved the video job without the need for any apparatus and physical equipment, and promised a smooth shooting, showed a great improvement. Now, how do you make a steady video? Let’s take a closer look at these two technologies, OIS and EIS technologies that answer the question.

WHAT IS EIS?

EIS (Electronic Image Stabilization) as can be understood from its expansion, it is a technology that tries to balance the shot image electronically. As can be understood from the expansion. In this system, which works at the time of shooting, the software tries to bring the image to a smooth state. It can deliver just as good as optical stabilization, but even with the best EIS it is necessary to compromise video quality for a steady image. Because EIS software can cause blura and edge cropping in videos to make the image steady.

WHAT IS OIS?

OIS (Optical Image Stabilization), as can be understood from its expansion, it is a technology that tries to balance the shot image optically. It works at the time of shooting and provides a physical performance. Optical image stabilization is directly related to the lens used by the camera, not the camera. OIS is not just for making steady videos; It is also good at taking successful photos, as it prevents unnecessary light leakage into the camera, especially in night photos. Its zoom performance is also superior to electronic image stabilization. However, the blur caused by the rapid movement of the surrounding objects cannot be prevented with optical image stabilization.

Difference of EIS and OIS

However, it should be noted that it is possible to eliminate this problem by using electronic stabilization and optical stabilization at the same time. Besides, the iPhone cameras that do this job properly are also visible. On the other hand, if you attach a tool using both EIS and OIS technologies to a stabilizer, you can produce videos that slide smoothly like oil. In fact, VIVO, which has come to the forefront with its innovative and revolutionary designs in recent years, has a wonderful phone model with a tiny stabilizer, OIS and EIS, which it introduced at APEX 2020.

Apart from that, there are also action cameras currently in production. Go Pro, which offers a great EIS technology called HyperSmooth, and Dji Osmo Action with a screen in front are some of the products that can be bought. And there is another product called Dji Osmo Pocket that appeals to youtubers, but the image quality is not as good as it seen in the ads.

The product called Dji Osmo Action, which I wanted so much for a while.

PHONES WITH OIS

Even phones with OIS are now produced, but it is necessary to look carefully at their features. Thankfully, users became aware. When I was in high school, they didn’t even write the graphics card of the computer they sold on the brochures. They are now typing because users request this information. For example, a group of customers are now only interested in OIS phones. They care more about this than any other comment about the camera.

Especially when we are going to buy a technological product, it is necessary to do research, find out what the features really mean and buy that. Today we know that a multi-megapixel camera doesn’t matter if you’re not going to get wall-sized prints. The important thing is the ISO range, fixing technologies and technical details like OIS or EIS. For example, if you are going to buy a smartphone, it is necessary to do research not on sales channels but from independent sites such as GSMarena. The site in question even has a detailed filtering screen that allows you to search for phones with OIS only.

NOTE

How to make steady video? There is another answer to the question that did not work at the same time of video shooting. There is another technology called Digital Image Stabilization. It is a post-processing method to process videos after they are taken and to reduce the difference in motion between frames, but it is expensive. It requires advanced hardware. Because of that not important for standart customers. But let’s explain. The logic is this: for example, you have a clip shot with a device that captures 30 frames per second. There are softwares that compensate for this 30-second movement, that is to find and edit even one-30th of a second, but there are handicaps such as skipping very moving frames.

That’s all I can do. How to make a steady video? Hopefully I have helped you find the answer to our question. I have been try to resolve the uncertainties about EIS and OIS technologies. If you want to see real experiences, there is an example that examines the test made by videos.
