What is EIS?

EIS definition

EIS, or Electronic Image Stabilization, is a camera technology that helps reduce shakes and vibrations in videos. Instead of using moving hardware parts, EIS works through software. It analyzes each frame of the video and adjusts the image to make the final result look steadier.

When you record a video while walking, running, or even holding the phone in your hand, small shakes are unavoidable. EIS tries to smooth out these movements by cropping the frame slightly and aligning it with the next frame. This gives the impression of a stable, controlled shot.

Many smartphones use EIS for everyday video recording, especially in features like Super Steady Mode, ultra-wide videos, and selfie videos. It is also useful in low-light conditions where natural hand shake becomes more noticeable.

Why EIS is useful

  • Reduces hand shake in videos
  • Improves stability while walking or moving
  • Works well with selfie cameras
  • Helps in low-light video
  • Uses less power compared to mechanical solutions

EIS vs OIS

  • EIS is software-based and adjusts frames digitally.
  • OIS is hardware-based and physically moves the lens or sensor.

Many modern phones use both systems together for better stabilization.
