With a normal camera, the user must manually adjust the parameters according to different light conditions. YI 4K Action Camera makes it easy for you, it senses the change of the light condition with CMOS, and ISP processor will adjust the frame rate and parameters automatically and to produce the highest image quality at low light.

100% of the wide-angle lens distortion correction

Count down, then photo capture.

Countdown：3, 5, 10, 15s

Press the shutter button to capture a series of photos.

YI 4K Action Camera has multiple high-level settings such as shutter at an exposure time of 30 seconds; Exposure Value compensation setting (EV), Setting of level of sensitivity (ISO); Metering Mode; White Balance (WB); etc. Together with the choice of 9 shooting modes, you can make impressive work like a professional photographer.

Users can adjust the white balance settings to change the overall color of the video or photo.

Change the camera sensitivity to light in low light conditions, in order to enhace the brightness of the videos and photos. In low light conditions, high ISO value will grant a brighter picture, but will also increase the noise level, making it grainy.

It influences the brightness of the video or photo. When shooting in a contrasting light environmental conditions, you can adjust this parameter to control the brightness of the video or photo. Value adjustment will increase the brightness of the video or photo based on the default basis.

-2.0, -1.5, -1.0, -0.5, 0（Default）, +0.5, +1.0, +1.5, +2.0

Divided into two metering modes: spot and center.

Divided into high, medium and low grades.
