What is OIS? OIS, EIS, HIS camera in smartphones

Smartphone cameras are built from many parts, from sensors, and lenses to laser focusing systems. Image Stabilization is one of the most grateful fundamental blocks of a great smartphone camera. Image Stabilization is necessary for blur-free, smooth images you click from your smartphone camera. Without this, your Images come out blurry and messed and the video will look like they are shot by a running person.

Without Image stabilization, you could not imagine your smartphone camera shots. You can stabilize your phone with a tripod or monopod. But you can't carry them always that's why we need Image stabilization.

let's talk about OIS, EIS, and HIS

Optical Image Stabilization (OIS)

OIS is a hardware solution. It uses a micro-electromechanical system (MEMS) gyroscope to detect movement and adjust the camera system accordingly. 

To Stabilize your camera it slightly moves your camera in the opposite direction of your hand moved or shaken.

for example: If your hand moved from right to left, OIS will slightly move your camera from left to right, to make shots clear.

Because this is a Hardware thing, doesn't require any cropping image, and your shot comes out large and wide. 

EIS (Electronic Image Stabilization)

EIS (Electronic Image Stabilization) is an abbreviation of Electronic Image Stabilization - an image enhancement technique using electronic processing.

EIS is useful for minimizing blur and shakey effects in smartphone camera photos. While Capturing images a little movement can ruin the image.

While capturing images image processor traces data from the image sensor in real-time. And after many other processes, EIS makes your Images Blur free and clear. 

HIS (Hybrid image stabilization)

Hybrid image stabilization (HIS), as the name suggests, means that the camera combines optical image stabilization (OIS) and electronic image stabilization (EIS) simultaneously.

With Hybrid image stabilization taking blur-free videos becomes easy in challenging conditions. There is an optimized algorithm that runs OIS and EIS at the same time. It captures blur-free videos and images. Optical Steady Shot is also an improved algorithm to run EIS and OIS in the most optimized way, and this can take blur-free and clear videos in low light even while walking.
