"The 3D structured light face unlocking method is a very safe unlocking method!"

"This time we placed an environmental sensor, a distance sensor, an infrared lens, and a dot matrix sensor in the notch of the phone, a total of 8 sets of sensors!"

"Using infrared refraction and distance sensors to perform formal 3D composition, a total of more than 30,000 points on the user's face are recorded in an instant, ultimately forming a 3D facial composition!"

Note3pro’s face unlock this time is a major upgrade in the entire industry.

For example, the current mainstream 2D ​​face unlocking and 3D face unlocking have higher security.

Even on the stage screen at the press conference, it was written that "3D face unlocking is 2500% more secure than 2D face unlocking."

However, netizens who are watching the press conference are not too concerned about 3D face unlocking. After all, in their opinion, the difference between 3D face unlocking and 2D face unlocking is just that, and the practical forms are exactly the same.

“This unlocking method is useless, and it also gives the phone such an ugly big forehead!”

It’s just like the barrage in the live broadcast room said.

Most netizens believe that this unlocking method is not much better than 2D unlocking.

After all, it is the rice company that is releasing this technology now.

Users who follow the company are not interested in such unlocking. Some users even think that adding this unlocking method will increase the cost and increase the selling price of the product in vain.

Compared with the 3D structure face unlocking method, the optical telephoto screen unlocking method is highly sought after by netizens.

A light touch of your finger.

The screen emits bursts of light.

In about a second, the phone will be unlocked!

Obviously, the optical short-throw screen unlocking method is much more popular than the 3D structure face unlocking method.

These two unlocking methods are unique to note3pro and are also a major selling point of this product.

As a regular version, note3 only uses traditional side capacitive unlocking.

Of course, Zhou Zhen has not never thought of adding two advanced unlocking methods, optical short-focus fingerprint unlocking and 3D structured light face unlocking, to the regular version.

It's just a pity that the configuration adopted by note3 is destined to make this model unable to use these two unlocking modes.

First of all, optical short-throw fingerprint unlocking requires very high light transmittance of the screen.

Although the OLED screen made of r2 material and the under-screen sensor developed by the company can also achieve optical fingerprint unlocking, the unlocking speed takes close to 2 seconds.

At the same time, there is a certain degree of error in the unlocking process, and the fatal flaw of optical fingerprint unlocking failure may occur in outdoor bright light environments.

In order to ensure the basic smooth experience of Note3, Zhou Zhen finally had to cancel the optical fingerprint unlocking on the regular version.

As for the 3D structured light unlocking method used in the big cup version, it has high requirements on the NPU and AI algorithms of the mobile phone processor.

Although the performance of the Fire Dragon 660 processor chip used in the regular version is pretty good, this processor chip is a mid-range processing chip after all.

Other aspects of the CPU and GPU are far inferior to the Fire Dragon 835.

If this unlocking method is used on the 660 note3, the unlocking speed will be further slowed down.

For this reason, Zhou Zhen can only use these two advanced unlocking methods on the big cup version.

In addition to this upgrade, the Big Cup version also upgraded the processor chip, using the Fire Dragon 835, the strongest processor chip in the Android camp.

Most netizens breathed a sigh of relief after seeing that the big version uses the Fire Dragon 835 processor.

After all, with such an excellent screen and such an excellent back cover design, if it uses the Fire Dragon 660, a mid-range processor chip, it will be a disaster.

At the same time, there are also certain upgrades in terms of battery and charging.

Big 4000 mAh battery!

22.5w wired charging!

5w wireless charging!

note3pro is also one of the phones with the best charging and battery life among all rice models currently released.

And in terms of image photography.

Rice note3pro adopts the "23" design scheme.

The front camera uses the same two front lenses as the regular version.

But what is interesting is that the large version of the front camera has two LED lights that can fill the light at the connection between the bangs and the middle frame.

Front dual camera LED light!

A perfect front-facing camera.

Although it is not as good as the front-facing camera of Blue Factory, looking at all rice products, the front-facing camera of rice note3pro is top-notch.

The rear camera of note3pro also adopts a three-camera design for the first time.

This is also the first mobile phone with a three-camera lens among mainstream brands.

The most mainstream camera on the market now is the dual-camera design.

In the original history of mobile phone development, ever since Juchang's p20pro adopted a three-camera lens, various mobile phone manufacturers have worked hard on the number of lenses on their mobile phones.

In order to improve the image quality of the model, Zhou Zhen directly gave the rice note 3 pro a three-camera design!

Wide angle super wide angle telephoto!

The wide-angle lens is what most users call the main camera.

Generally, the main camera lens has 1x and 2x modes, and the 1x photo mode is actually a wide-angle photo.

The 2x photo is the normal straight-out photo, that is, what you see is what you get.

In terms of mobile phone sensors, Zhou Zhen used the imx378 12-megapixel sensor as the wide-angle main camera for the Mi Note 3 this time.

The ultra-wide angle uses Sony imx386, and the telephoto lens uses Sansan s5k3m3 sensor.

All three cameras have 12-megapixel lenses.

Among them, the ultra-wide-angle and telephoto lenses use the modules of rice phone 6 and rice phone note3.

On the contrary, the wide-angle main camera uses an old sensor imx378 that performs very well.

The imx378 sensor was once used on the rice phone 5s, and its overall performance level is better than the imx386 on the rice phone 6.

After all, imx378 is a 1/2.3-inch sensor, while imx386 is a 1/2.9-inch sensor.

In terms of unit pixel, imx378 has reached 1.55um, which is also the sensor with the largest unit pixel among the current public sensors.

You must know that the direct unit pixel of the Sony imx586 sensor released in 2019 is only 1.6um.

This means that the direct output level of this sensor is very close to that of imx586.

The unit pixel area of ​​the imx386 sensor used on the rice phone 6 is only 1.25um.

Is the main camera sensor of rice 5s better than rice 6?

It is indeed better in terms of parameters and theory.

But the main advantage of the imx386 sensor lens is portrait photography and the corresponding thinness and lightness.

In order to make the lens of the back cover of the phone completely parallel to the back cover of the rice phone 6, it can only use the smaller and thicker imx386.

However, the imx386 is a very compatible lens and can be used with other lenses to take excellent portrait photos.

The credit for "Double-zoom camera, more beautiful photos of people" in the promotional slogan of the rice phone 6 is attributed to the imx386 sensor.

In order to make the Mi Note 3 Pro more powerful in taking photos, Zhou Zhen specially used the imx378 as the wide-angle main camera.

At the same time, imx386 is also retained to serve as an ultra-wide-angle and portrait lens.

This kind of design allows the mobile phone to take more excellent photos with the large bottom and large pixels of the imx378 when taking daily photos.

When shooting portraits, you can use imx386 to take good portrait photos.

At the same time, this time the sensor focal length has been extended for the telephoto lens, allowing the sensor to support an equivalent 3x optical zoom and have better telephoto performance.

In addition, in order to make the mobile phone take better photos this time, Zhou Zhen has adopted four-axis optical image stabilization on all three cameras.

With the support of this series of hardware configurations, the photography performance of note3pro has been improved again.

The regular version of the speaker and NFC upgrades are also available on the Pro, which is even more powerful than the regular version.

Among them, the sound cavity volume of the regular version of the speaker has been increased by 25% compared to the volume of the Mi 6 speaker.

This time, the speaker size of Pro is 10% higher than that of the regular version of note3, and the overall volume is nearly 38% larger than the speaker of rice 6.

In addition, in terms of linear motor, it uses a horizontal linear motor that is 70% larger than the rice phone 6.

In order to make a high-end flagship mobile phone, Zhou Zhen basically added all the available hardware configurations.
