Image stabilization is an important capability for many electro-optic sensors, where an operator or user is required to view the output imagery. The technique can therefore enhance many practical viewing systems, spanning a very broad range of applications including those found in defense and security sectors.

Stabilization provides a means for reducing both image blur and unwanted frame-to-frame image shifts and rotations, thereby aiding image interpretation and reducing the operator’s workload. For those systems that require the operator to locate or classify features within the video stream (typically recognition and identification), then a stabilized image stream will help improve the accuracy of these tasks.

There are a number of techniques for stabilizing an image which are either based on mechanical correction or image processing. Mechanical stabilization techniques include those that gyroscopically stabilize the whole camera system or use elements within the camera to effectively move the lens or detector array.
