Yi Technology debuted the new Yi 4K+ Action Camera at CES 2017, promising UHD 4K (3840×2160) acquisition at up to 60p.
The camera is powered by a quad-core ARM Cortex-A53 64-bit CPU, and Yi says it's the first camera to use Ambarella's H2 image processing system. The sensor is a Sony IMX377 1/2.3-inch 12 megapixel Exmor R CMOS. (The camera's resolution maxes out at 4000×3000, but it can only capture in that mode at 25p or 30p.) Electronic image stabilization is enabled via integrated gyroscope and accelerometer.
The 4K+ records H.264 .MP4 video at a maximum bitrate of 135 Mbps. (A USB 3.0 Type-C connector helps move the bigger files off the camera faster.)
Assuming the overall quality is up to snuff, the new camera could give GoPro a headache — reviewers of previous models have reported that Yi's cameras are, more or less, solidly designed clones of more expensive GoPro products. But the 4K+'s price and ship date have yet to be announced.
Yi was also showing its $350 M1 mirrorless camera, first introduced at Photokina last year.
