EIS

EIS stands for Electronic Image Stabilization. Unlike Optical Image Stabilization (OIS), which physically moves parts inside the camera to counteract shake, EIS uses software algorithms to reduce motion blur and stabilize videos after the image is captured.

Here’s how it works:

The camera records a slightly larger frame than what you see in the video.

Software analyzes the frames to detect movement or shaking.

It then crops and adjusts the frames digitally to smooth out the motion, making videos appear steadier.

EIS is especially useful for video recording, helping reduce jitters when walking or moving. It works well in combination with OIS for even better stabilization.

While EIS can’t correct large shakes as effectively as OIS, it helps improve video quality without adding extra hardware, making it a common feature in many smartphones today.
