Smart Cameras to Help You Take Better Photos
Google Clips
One of the latest to launch is Google Clips. It is designed to be put somewhere in a room to take pictures by itself. It can also be attached to an object or a person's clothing.
Google says machine learning helps the camera choose the best times and situations for taking pictures and videos. Interested buyers can join a waiting list to be informed when it is on the market.
GoPro Hero
GoPro also uses machine learning to power its QuikStories characteristic. This tool takes existing photos and videos and automatically creates a finished video piece, complete with music and effects.
Snap Spectacles
Messaging app Snapchat sells a pair of sunglasses with a builtin camera that can record short videos with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “catch the moment, without taking you out of it”．
The glasses can record short video clips that can be shared with Snapchat users. Snap Inc. has started selling its Spectacles sunglasses online in the United States.
Apple iPhone X
Apple's new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous ones that used a fingerprint to unlock the phone.
Apple says the system works by projecting more than 30,000 dots on the face to create a kind of map. Apple says its facial recognition is even secure enough to allow payments through its Apple Pay service.
