With the new iPhone, Apple claims that it\u2019ll help you with three things: photo and video effects, precise placement of AR objects, and object and room scanning. The last two applications might be largely for developers and businesses like construction that need to map the room. For an average consumer, photo and video effects might be the most interesting part.<\/p>\n
Because LiDAR can work in the dark by shooting lasers to calculate distances, Apple\u2019s using it to improve the autofocus on the high-end iPhones. The company claims that because of the sensor the iPhone 12 Pro phones has 6 times faster autofocus in low light as compared to a normal camera. Plus, the LiDAR sensor enables the device to take better portrait mode photos in low-light conditions.<\/p>\n The concept of using a dedicated depth sensor is not new. Plenty of mid-range phones such as the OnePlus Nord<\/a> use a depth sensor camera to enhance portrait mode photos. But these sensors work better in the daylight than low-light. Some devices such as the Huawei P30 Pro<\/a> and the Samsung Galaxy S20 Ultra<\/a> have a time-of-flight (ToF) sensor. It uses infrared rays to maps the surroundings. You can read about the ToF sensor<\/a> in our explainer here<\/a>.<\/p>\n While both ToF and LiDAR can only scan the area up to a few meters in phones, some variants of the latter can measure distances more than 100 meters. However, those are used primarily on top of cars. The advantage of having a LiDAR sensor is that it sends smaller pulse rays<\/a> from one corner to another to \u2018scan\u2019 the area. On the other hand, ToF sensor sends a single flash pulse to measure the area, and that can cause more accuracies when distances are calculated.<\/p>\n Here is iPad Pro\u2019s LiDAR under infrared. pic.twitter.com\/IZkum3nwRx<\/a><\/p>\n \u2014 Faruk \ud83d\ude80 \u1d35\u1d3e\u1d34\u1d3c\u1d3a\u1d31\u1d30\u1d3c (@iPhonedo) March 26, 2020<\/a><\/p>\n<\/blockquote>\n Having a LiDAR sensor on a phone will encourage more developers to probably find better uses cases for AR that are more convincing than one-time amusement demos. Snapchat has already confirmed that it\u2019ll ship LiDAR-powered lenses<\/a> on its iOS app.<\/p>\n Apple might not be able to convince you to buy its high-end modes just on the basis of the LiDAR sensor. However, the company hopes that if you\u2019re an AR developer or someone who cares for quality low-light photos, it could one of the reasons for you to spend a few more dollars.<\/p>\n For more gear, gadget, and hardware news and reviews, follow Plugged on Twitter<\/a> and Flipboard<\/a>. <\/i><\/p>\n Published October 14, 2020 \u2014 07:02 UTC <\/p>\n![](\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2020\/10\/Apple_nightmode-demo-photography_10132020.jpg\")
