In this blog we tried to explain Sensor-Shift Stabilization, a new image/video stabilizing technology used on iPhone 13 Series (previously used on iPhone 12 Pro Max) of Smartphones.
To refresh your memory, Sensor level Stabilization was first introduced in the iPhone 12 Pro Max last year, but Apple has now included it in the whole iPhone 13 lineup this year. This makes us think about whether it’s a groundbreaking technology or how will it improve overall photography experiences. So this article will give you a clear idea.
Before going into the main topic first let’s get to know about stabilization on photography/videography. In photography, image stabilization is a frequent word. Simply explained, image stabilisation (simply ‘IS’) allows photographers to capture blur-free photos and movies without the use of a tripod. Any camera with built-in image stabilisation can shoot at slower shutter rates than one without, resulting in a cleaner, sharper image. There are several types of image stabilisation, but we will focus on sensor-shift and optical image stabilisation.
iPhone 13 Series’ Sensor Shift Stabilization Explained:
To understand this tech, first, let’s get to know about Optical Image Stabilization (OIS) which is primarily used on almost all Android Flagships. Moving the lens is what OIS is all about. The lens is installed in the camera module in such a way that it can move along an axis in this configuration.
A two-axis OIS allows the lens to move in two directions (left and right or up and down), whereas a four-axis OIS (used on Vivo X60 Series) allows the lens to move in all four directions. At least, in theory, moving in all four directions is preferable. When you take a photo and your palm shakes slightly to the right, the phone can adjust by detecting the tremor and moving the lens to the same side. Electromagnets and sensors are used to do this. As a result, the final image isn’t as hazy as it would have been if OIS hadn’t been used.
If you understand the above paragraphs about OIS it’s very simple to know about Sensor-Shift Stabilization. This method of Stabilization, like OIS, utilises magnets and sensors to move an object within the camera module. Instead of adjusting the lens, it moves the sensor to counteract camera shake.

OIS Vs Sensor Shift Stabilization
The image quality difference isn’t significant, but there’s another way around which we can think. External lenses can now be attached to smartphone cameras nowadays, but it’s nearly rare to find external smartphone lenses with built-in OIS, which means that shooters who use multiple lenses will struggle to resolve the phone’s own lens with an external one.
In this kind of situation, this Apple tech comes to the rescue as the sensor level stabilization can theoretically stabilize the image/video even when you use any external lens to shoot that particular video/photo. Both OIS and SSIS aid in low-light photos, but the entire camera software of a phone manufacturer is far more essential. This distinction, though, can be significant for professionals.
Top-up Your Knowledge About EIS!
EIS (Electronic Image Stabilisation), takes the image and enlarges it to the point where it fills the entire sensor. In order to counter any movement, the software examines the image for any evidence of movement. Because it is purely computer-based, the efficiency is totally dependent on the quality of the software. Many OEM's use both EIS and OIS to bring best results possible.
