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

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.

Sony's IMX377 image sensor Lower power and low light

IMX377 is Sony's new image sensor. Compared with previous versions, it captures high resolution image but consumes less power and also deliver better image quality at low light. IMX377 sensor supports 3840*2160 ultra-clear 4K video resolution and 12M pixel photo. It has 1.55um high sensitivity large sensor pixel size which helps produce bright images with clear details and less noise even in poor lighting conditions.
