Xiaomi 4k camera Highlights:
Sony IMX377 image sensor
Equipped with Sony IMX377 sensor, Xiaomi Yi 4K cam enables you to capture high resolution images with less power and low light. The IMX377 supports 3840*2160 ultra-clear 4K video resolution and 12M pixel photo. With 1.55um high sensitivity large sensor pixel size, it helps produce bright images with clear details and less noise even in poor lighting conditions.

Ambrarella A9SE75 SoC Processor
The heart of the yi action camera 4k is its Ambarella A9SE75 SoC, 800 MHz dual-core Cortex-A9 ARM processor with 28nm CMOS technology and high-efficiency Digital Signal Processor (DSP). It supports H.264 BP/MP/HP encoding with low-power consumption, even at UHD 4K resolution. The upgraded SoC supports lens distortion correction for the wide-angle lens and offers built-in Electronic Image Stabilization (EIS), 3D noise cancellation, and 48 kHz stereo audio.

Electronic Image Stabilization
To help fight against vibrations and reduce shakiness, the xiaomi 4k camera features built-in Electronic Image Stabilization(EIS). It uses built-in 3-axis gyroscope and 3-axis accelerometer sensors to detect position and motion change and uses algorithms to compensate for unwanted movement and produce clearer, more stable looking footage. Yi 4K IQ EIS
Lens Distortion Correction
Wide-angle distortion is common to many action cameras that often results in a fish-eye like effect. Rather than have to correct this in post-production, the YI 4K eliminates this step by offering in-camera lens correction for reduced distortion and more naturally looking images.
One-Button and Touchscreen Control
With simple and intuitive design, everything can be operated and controlled using one single button and the build-in real LCD touchscreen. Wake up the xiaomi camera 4k from sleep mode in just 1 second so you won't miss a moment. Even when powered-off, the camera can be ready to record in just 3 seconds.

360°Omni-Direction Dual Microphones
The yi cam 4k uses dual omni-direction microphones to record 48 kHz stereo audio, which is recorded in the AAC format. High-sensitivity and high signal-to-noise ratio of the microphones provide clearer audio in noisy environments. Manual IQ parameters settings
Besides auto control modes, xiaomi 4k action camera allows you to manually set IQ parameters such as Shutter, Exposure Value Compensation (EV), Level Sensitivity (ISO), Metering Mode, White Balance (WB) and more easily. There are 9 shooting modes for you to choose.

Cutting edge Microsoft Hyperlapse Pro technology
The xiaomi yi 4k camera is now natively supported by Microsoft Hyperlapse Pro technology for flawless time lapse videos. This technology uses video frames to recreate 3D space and resample the video frames from the 3D space to create smoother and time lapse video which is perfect for sharing.
