[Photography Skills] What is OIS (Optical Image Stabilization) in phone shooting?
Welcome to Blackview blog. Hope the guide helps.
Ever wished your shaky hands didn't ruin that perfect photo op? Well, fret no more! Many smartphones, such as some Blackview rugged phones, boast a feature called Optical Image Stabilization (OIS), your secret weapon against blurry pictures and shaky videos. It is one of the most useful smartphone photography skills that worth to learn. Let's dive into what OIS is and how it can take your mobile photography to the next level.
What is OIS?
OIS is a technology that combats camera shake, ensuring sharper, clearer photos and smoother videos. It will help you to take better selfies. It works using tiny gyroscopes and motors within the camera lens. These gyroscopes detect any unwanted movements, like your hand shaking, and the motors subtly adjust the lens elements to compensate. Imagine tiny ninjas counteracting your every wobble!
Benefits of OIS
OIS comes in handy in various situations:
- Low-light photography: In low-light conditions, your camera needs a slower shutter speed to capture enough light. This makes your photos more susceptible to blur from even slight hand movements. OIS counteracts this, allowing you to capture clear low-light images without a tripod.
- Zooming in: When you zoom in on your phone camera, even small shakes are magnified. OIS keeps things steady, ensuring crisp zoomed-in photos.
- Action shots: Capturing moving subjects, like kids playing or pets running, is tricky. OIS helps stabilize the camera, minimizing blur and producing sharper action shots.
- Smooth Video: Shaky videos are unpleasant to watch. OIS ensures smoother, more professional-looking videos, perfect for capturing memories or vlogging.

OIS vs Electronic Image Stabilization (EIS)
There's another player in the stabilization game: Electronic Image Stabilization (EIS). Unlike OIS, EIS is a software solution. It combats shake by cropping into the image, essentially giving the software room to adjust for wobbles. While EIS is helpful, it can slightly reduce image quality and sometimes create a distortion effect in videos. OIS generally offers superior stabilization without these drawbacks.
Do you need OIS?
OIS is a valuable feature, especially for low-light photography and shaky hands. If you prioritize capturing clear photos and videos in various conditions, OIS is a worthwhile investment. Many mid-range and high-end smartphones now come equipped with OIS, so keep an eye out for it according to your needs when choosing your next phone.
