What is OIS?
Optical Image Stabilization - hardware that reduces camera blur from hand movement.
OIS (Optical Image Stabilization) is a camera technology that physically moves the lens or sensor to compensate for hand shake. This results in sharper photos and smoother videos.
How OIS Works
Gyroscope sensors detect motion, and micro-motors adjust the lens position in real-time to counteract movement. This happens thousands of times per second.
Benefits of OIS
- Sharper Low-Light Photos: Allows longer exposure times without blur
- Smoother Video: Reduces shake in handheld video recording
- Better Telephoto Shots: Essential for zoom lenses that amplify shake

OIS vs EIS
OIS is hardware-based and doesn't crop or process the image. EIS crops and digitally stabilizes, which can reduce quality. Many phones use both together for best results.
Most flagship and many mid-range phones now include OIS on their main cameras.
