DJI is a Chinese drone manufacturer and the world's leader in creating and marketing consumer unmanned aerial vehicles. In May 2017, DJI introduced Spark, the first drone that users can control simply by hand gestures. The Spark is a mini camera drone that takes off from a user's palm. Spark can do this thanks to DJI's new 3D vision sensor technology, as well as its use of machine learning and computer vision. New video and photo editing tools enhance the ability to share photos and videos. In January 2018, DJI unveiled the Mavic Air, a drone with a camera that can shoot in 4K, a three-axis gimbal (to improve stabilization), and an estimated 21-minute flight time. According to the retail consultancy NPD, DJI commands two-thirds of the U.S. drone market when measured by revenue. In 2018, the company launched four new products. Its Ronin-S handheld stabilizer immediately became the standard tool for video makers and other creators who need three-axis stabilization for mirrorless and DSLR camera systems. The Osmo Mobile 2 handheld stabilizer put that same technology to work for smartphones, allowing anyone to benefit from that professional technique. In the air, DJI introduced a new flagship prosumer drone, the Mavic 2, as well as a new consumer drone, Mavic Air. Both feature innovations in propulsion, power management, obstacle recognition and autonomous flight, for groundbreaking possibilities in aerial photo and video creativity.
