The cameras in our smartphones keep getting better as they gain tech and features previously reserved for high-end cameras. One such example is Optical Image Stabilization (OIS) which promises less blurry images and smoother video. Here we look at exactly what OIS is, how it works, and whether it’s a feature you’ll want in your next smartphone.
Optical Image Stabilization has been around commercially since the mid-90s when it started being used in compact cameras and SLR lenses as a method of letting photographers shoot longer exposures without reaching for a tripod. It works by moving lens elements to counteract wobbly hand-induced camera shake, thereby reducing blur.
Twenty years later, OIS has now become a mainstay feature of flagship smartphones where it’s arguably even more useful. Because the image sensors used in smartphones are so much smaller than those in traditional cameras, they can struggle to get enough light in some conditions. As such, they’ll often end up using exposure times which increase the likelihood of camera shake and blurry images.
How Camer’s Work?
Camera’s have a light detector. It can be a charge coupled device or a CMOS image sensor. This piece of electronic equipment that converts incoming light rays into electrical signals.
