Electronic Image Stabilization
February 28, 2020

Unique hybrid implementation. Lightning fast image processing. Best-in-class motion estimation.

Electronic Image Stabilization eliminates the effect of hand jitter and flight navigation vibration by correcting for 6 degrees of freedom, including rotation, translation, lens distortion and rolling shutter effects.

This solution is one library with three deployment modes, addressing different market configurations:

Low Latency
Stabilization during the image acquisition for ultra low latency applications (e.g. – sports broadcast, remote control flight).

Real-Time
Stabilization just after the image acquisition for action camera and smartphone streaming.

Deferred Correction
Delayed stabilization for smooth camera trajectory for high quality applications such as action cameras, smartphones or drone streaming.
