Huawei launches P20 Pro smartphone with triple rear camera

Huawei has unveiled the world's first triple rear camera system on a smartphone, which will use artificial intelligence (AI) to help users take photos. The Chinese firm said the new £800 ($1,130) P20 Pro uses AI to identify objects and scenes in the camera's view and adjust its settings accordingly. The smartphone can snap photos in near-dark conditions without using its flash or a tripod by taking exposures lasting up to six seconds to get enough light. Its AI system adjusts the camera's settings to avoid the blurring and smearing that often plagues photographers employing this technique handheld. The P20 Pro is the flagship device among three new phones the company announced at an event in Paris, where the P20 and P20 Lite were also introduced.
