The YI 4K consumes less power and delivers better low-light performance than the previous generation sensor thanks to large 1.55µm pixels.
The heart of the YI 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.
