Ming-Chi Kuo explains the technology behind Face ID

The sensors used for Face ID


Apple will introduce its 2017 iPhone models on September 12th, and a leak found in the Gold Master version of iOS 11 suggests that the new phones will be known as the Apple iPhone X (the tenth anniversary edition), the Apple iPhone 8 (sequel to the iPhone 7) and the Apple iPhone 8 Plus (sequel to the iPhone 7 Plus). Pre-orders could start on September 15th with all three models set for a September 22nd launch.

Earlier today, we showed you a video that revealed how Apple iPhone X users will set up Face ID so that the facial recognition system can unlock their phone or verify their identity. The man who called Apple's facial recognition system (which involves a 3D sensing front-facing camera) "Revolutionary" back in February, is now weighing in on the technology employed by this feature. KGI Securities' Ming-Chi Kuo, considered to be one of the best Apple analysts in the business, sent out a note to clients today showing them exactly how Face ID works.

Kuo says that Face ID relies on four components including a structured light transmitter, a structured light receiver, a front-facing camera, and a time of flight/proximity sensor. The sensors that are used for Face ID are found in the "Notch" at the top of the display. The structured light sensors collect depth information which is combined with images taken with the front-facing camera to produce 2D images. Using software algorithms, a 3D image is created and that image is used for facial recognition. The proximity sensor can warn iPhone X users when they are holding the handset too far away, or too close to the user's face to produce an accurate 3D image. To make sure that these sensors work perfectly out of the box, they all must be aligned before final assembly.

According to Kuo, all iPhone X models (expected in black, white and gold) will have a black coating on the front glass in order to hide the sensors involved with the four components. The ambient light sensor supports the True Tone display technology originally introduced in 2016. Using the ambient light sensors, the temperature of the colors on the phone's screen is changed. Kuo says that this will improve the performance of the 3D sensing feature.

Apple turned to facial recognition once it became obvious that the edge-to-edge screen on the iPhone X would prevent the use of a Touch ID button on the phone. And current technology won't allow Apple to embed a fingerprint scanner under the display at this time. Kuo doesn't see either Apple or Samsung offering such a feature until the 2018 Samsung Galaxy Note 9 is released next year.

Does it work in the dark? So it don't have a iris scanner?

It appears it has an IR sensor as part of the recognition hardware, which would work in the dark.

it better work at night. that is one gripe i had about it. it should also work at angles where you have have to put your face directly in front of the camera.

This is not Samsung dude. Again, most had doubts about Touch ID......

Don't you think apple must have thought about this? like the article explains, Yes, it'll work in the dark and it'll be better than anything else out there on the market. I can't wait to see this in full action along with the new design, screen, AR, new cameras, and new software features. This will be the best phone of all time.

"Yes, it'll work in the dark and it'll be better than anything else out there on the market."

"This will be the best phone of all time."

The latest predictions from Bankz are here, folks. In terms of being right, he loses to broken clocks 2-0 each day.

Sure it will be..... maybe to you sheep it will be.

Proximity sensor alone means there will be error rates. I am perfectly fine with the hold the phone farther or closer message I get with the iris scanner on the GS8 but I heard you sheep complain about it before and low in behold, this 3D camera needs a set distance to work properly too.

You sheep better have the same criticisms. Lol

You are talking as if you already received an iPhone X and you tried its FaceID. But I understand your frustration, not easy to digest Apple superiority.

Poor Sambomb sheeple......

So, you label him an Android lover just because he pointed you out for being a blind Apple sheep?
LMAO the stupidity!

lol idiot. The proximity sensor I was referring to is right there listed as one of the sensors. I don't have to own an iphone X to know how they work.

Are all isheep this moronic?

Proximity sensor "alone".

This is your sentence, so you forgot that Apple is behind it not Samsung (ps. Samsung for me means all the others).

I repeat that you are giving you bulls**t opinion on rumors and articles. Once you try iPhone X, the best phone for at least one year, come here and give your opinion. But I'm sure that once you try it you will enter in a deep coma.

Read the article idiot and read what a proximity sensor does. It judges how far your face needs to be to unlock. Which means there will be errors reading it if your face is too close or too far.

Just because you suck Apples cock so much it doesn't mean their proximity sensors turn off when you unlock the phone and it can read it from any distance. Think. If it could 100% read from any distance, why would they put a proximity sensor in the front camera in the first place? f**king moron I swear.

More like Apple trying to catch up others. AMOLED, edge to edge, wireless charging, facial recognition is not new, cut out screen either.
So who is trying to follow whom?

Apple is trying to catch up for android users. But for us who been an iphone users since iphone 3g, they are welcome upgrades. Love the simplicity and reliability of it. Also im tied to apple ecosystem.

"Love the simplicity and reliability of it. Also im tied to apple ecosystem."

Thank you for your honesty.

I understand that as a true statement without the hypocrisy of "its
Gimmicky , No one needs this useless feature, You'll get eye cancer Apple did it right, you'll have unrealistic colors, you'll get burn in right away---" etc..

Best to you with your purchase of what you like and want. I happen to think it looks like a great device.

Try to follow what?

Amoled screen?
Bezel-less design?
Tall form factor?
Wireless charging?

Take your lips off Tim's d**k for a second and smell the coffee bud.

I wasn't really to sure about it, not sure if it would be annoying to use, but it is impressive stuff.
