Electronic Image Stabilization (EIS) technology with 3-axis gyroscope and 3-axis accelerometer

2 (4)

Action videos usually require post-production to reduce shakiness. With YI 4K Action Camera, you can avoid extra time spent editing due to the camera’s Electronic Image Stabilization (EIS) feature. EIS uses built-in gyroscope and accelerometer sensor to detect position and motion change. When the camera tilts, moves, shakes or experiences impact, the sensors will send data to EIS and EIS will use image a cross-border compensation algorithm to compensate the change to produce stable videos.
