OIS, EIS or AIS which is the best image stabilization method, as smartphone cameras are narrowing the difference between a DSLR and mobile camera day by day, it’s also important to deliver the stability a DSLR provides.

Now what is Image stabilization and what is the need of it if you may ask, well suppose you want to take a shot of an object in medium to low lighting conditions then often we notice a blur in the images produced, this blur is generated by the slight movements of the camera or due to handshake, here Image stabilization comes into play, it compensates the movements and hence delivers a great looking shot free of any blur.

Well there are many Image Stabilization techniques nowadays and it could be confusing about how each one of them works differently from one another and which is the better one, we shall find out now

1.Optical Image Stabilzation  (OIS)

ois As smartphone cameras have smaller image sensor which needs them to shoot images at a higher exposure time which leads to production of blur in the images, the OIS method is used to control the path of light entering the camera during that exposure time, in OIS the path of the light entering the image sensor is compensated by using gyroscope sensors which provides information about the handshakes or camera shakes and then it produce a counteract shake to the lens module, here the lens module is moved to compensate the movements  with the help of electromagnetic motors.

Well OIS does have its limitations also, for instance if the subject is moving too fast then OIS can’t do much about it.

 2.Electronic Image Stabilization (EIS)


When compared to OIS, which is purely mechanical, EIS corrects the device shaking with the help of software. The blur-free results are achieved by perceiving patterns, interpretations digitally and thereby producing a counteract shake to minimize the blurs. Here the advantage that EIS offers is that it doesn’t need any additional hardware, hence making the Image Stabilization process on smartphones less bulky and cheap also EIS could be further improved by software updates, making this option a flexible choice for the manufacturers, nowadays we actually see a lot of budget smartphones boasting EIS as it is a fairly cheap alternative to OIS and serving the same purpose.

Well EIS comes with its disadvantages too, EIS achieves these results at the cost of image quality such as reduced field of view.

3.Hybrid Image Stabilization (EIS+OIS)

Hybrid image stabilization combines the advantages of both OIS and EIS, it incorporates the lens compensation module along with EIS algorithms to work on top of that resulting in blur free and shake free videos most of the time. Most of the flagships are incorporated with this Image stabilization method as it promises the best blur free results.

4.Artificial Image Stabilization (AIS)

The latest Huawei’s flagship P20 pro incorporates an image stabilization method known as Artificial Image Stabilization which detects the scene modes, analyses the environment and movements of the device and uses the on-board AI engine and algorithms to counteract the movements to produce blur free images and videos.

AIS paired with OIS looks solid and promising as AI algorithms are improving day by day in its capabilities and AIS could also be improved by software updates hence helping smartphone manufacturers to keep up the competition.
