What is EIS (Electronic Image Stabilization)?

Electronic image stabilization (EIS), also called real-time digital image stabilization, is used in many modern video cameras to stabilize the video they create without the use of a specialized mount to physically move/stabilize the camera. It is a stabilization technique that digitally zooms into the image slightly to create a zone of buffer pixels for when it needs to move the image. If sudden pixel movement over the whole scene is detected, it then ‘shifts’ the image data (left, right, up or down) from frame to frame of video all while comparing the pixels in the current frame to the previous one to counteract any physical motion of the camera and create a steady looking image.

EIS can be incredibly limited when it comes to long-range surveillance due to the narrow fields of view used in long-range cameras. For more information, please read our page on Gyro Stabilization.
