What is electronic image stabilisation?
Electronic image stabilisation (EIS) is an image enhancement technique that cancels out hand jitter or shaking when you’re filming a video or taking a picture, so your image isn’t blurry.
Because EIS isn’t limited by mechanical compensation that other optical stabilisation methods use, it can track and adjust video and images during fast-moving motion - for example, filming or photographing sports. It can even be used in drones to replace gimbals normally used to keep the camera steady during flight, as well as image-stabilised binoculars and telescopes.
How does electronic image stabilisation work?
EIS uses an accurate motion sensor in your phone’s camera for tracking the source of the shaking. This information about the camera’s motion is integrated into the video frame and EIS compensates for it by cropping the viewable image from a stream of video frames.
In short, when your phone shakes, EIS will counteract that movement to process a clean and stable image.
