YI 4K ACTION CAMERA
Main Processor
Ambarella A9SE chipset, includes a 800 MHz dual-core.Cortex-A9 ARM CPU and a high-performance digital signal processing (DSP) subsystem with a 32-Mpixel image sensor pipeline (ISP), and an advanced H.264 encoder capable of 4K resolution.
Image Sensor
SONY IMX377, 1/2.3", 12 megapixels CMOS image sensor with Exmor R ability.
Record a continuous video loop and overwrites itself until you press the shutter button to stop it and save.
Video length:5 min, 20 min, 60 min, 120 min, Max
Highly Advanced Technologies
Electronic Image Stabilization
Built-in 3 axis gyroscope and 3 axis accelerometer. Uses a cross-border compensation algorithm to compensate the motion change to produce stable video quality
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.

Self-defined IQ parameters for demanding customers
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.
WB (White Balance)
Users can adjust the white balance settings to change the overall color of the video or photo.
White Balance Setting
Recommended Lighting Conditions
Auto (Default)
Automatically adjusts the white balance via environment, without human intervention.
Native
The original color
Tungsten
3000K, tungsten or sunrise / sunset lighting conditions
Daylight
5500K, cool fluorescent, average daylight conditions
Cloudy
6500K, cloudy environmental conditions
ISO (Level of sensitivity)
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.
ISO-MAX for Video
Resulting Video Quality
Auto (Default)
Automatically adjusts the sensitivity according to the environmental conditions
400
Darker video in low light, minimum image noise
1600
Moderately bright video in low light, moderate image noise
6400
Brighter video in low light, highest image noise
ISO-Max and ISO-Min for Photo
Resulting Photo Quality
Auto (Default)
Automatically adjusts the sensitivity according to the environmental conditions
100
Bright photo in outdoor daylight, minimal image noise
200
Bright photo in indoor lighting, marginal image noise
400
Darker photo in low light, moderate image noise
800
Darker photo in very low light, increased image noise
EV (Exposure Value compensation)
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.
High-density lithium polymer battery, battery specification is 3.85V, 1400/1430mAH(min/typ), 5.39/5.51Wh(min/typ).
