After ending the conversation with Chen Shoutao, Kang Chi actually didn't take this matter very seriously.

Unless you're really bored at some point, maybe you might have fun and see if you can earn some mastery points by the way and relieve the tension of mastery points......

Early the next morning, just as Kang Chi was about to return to Dongyang and give himself a vacation, He Yongbin suddenly called him.

"We have basically understood Wu'an's technology, and only a few key technologies are still unclear."

"So fast?"

Kangchi was also a little surprised by their progress.

Although Daqin Optics can build cameras, in fact, the entire camera R&D department has not really understood the technology inside.

Just like when Kangchi first started to draw a scoop with a gourd, he could also build a production line for lenses, but he didn't know why he made it like this.

Therefore, during this period of time, Kangchi's main task for He Yongbin was to thoroughly understand Wu'an's technology.

After comprehending the technology that he can comprehend on his own, he will go over to explain the remaining technical difficulties to them.

In this way, they also have the ability to draw inferences.

It's just that this anti-three may just be a derivative product of the same technical level.

For example, mobile phone camera module, security monitoring and so on.

As for developing something more advanced......

They certainly can't be counted on.

It's not that Kangchi doesn't believe them, it's mainly that it's efficient and low-cost, and there's no need for it.

On the other side, when He Yongbin heard Kang Chi say that he was fast, he was actually not happy, but a little depressed.

The drawings and products are ready-made, or the company has recruited a large number of R&D personnel to conduct group discussions.

But it took more than a month,

Hurry?

Is this how much food do you think they have?

Of course, He Yongbin also admits that his own dishes are enough.

After all, when the manufacturing department has already started to build cameras, their R&D department is still figuring out the technical principles......

This strange situation is enough to explain everything.

After temporarily changing the itinerary, Kangchi soon came to the magic capital, and then in the next few days, he gave classes to each technical group one by one to solve problems.

By the time the entire R&D team had thoroughly understood Wu'an's technology, a week had passed.

——

Friday afternoon, Daqin Optical Camera R&D Department, conference room.

He Yongbin and the others all sat neatly in the conference room, looking at Kangchi with confidence and expectation.

After a week of patient counseling by the great god Kangchi,

They suddenly felt like they could do it again!

In particular, He Yongbin, who participated in the seminars of each technical group,

Kangchi helped him pierce more cellophane than he has even added up from more than ten years of research and development!

He felt as if he had been opened up to the second pulse of Ren Du and completed a rebirth.

It is worthy of a man who can make a camera at the same time, but also a lithography machine!

He Yongbin silently made a deep review again in his heart.

You shouldn't have suspected that the new boss is unreliable before,

He was a little scared now, this boss was too reliable, and he casually took out something that made him feel like a primary school student......

"After this week's training, you have basically mastered the technical principles of Wu'an camera, and then I will arrange a project for you."

Kang Chi looked at everyone present, and finally set his eyes on He Yongbin,

"This project is also your old business, the mobile phone lens module."

When He Yongbin heard this, he was slightly stunned.

originally thought that Kangchi wanted them to develop the second generation of Wu'an,

Or a mirrorless camera positioned at a higher end point,

I didn't expect it to be a mobile phone lens.

To be honest, he did a bit of a psychological shadow when he made mobile phone lenses before......

Kang Chi seemed to see the fear that flashed on He Yongbin's face, so he opened his mouth to encourage:

"Even Wu'an's technology has been thoroughly understood, I believe that making a mobile phone lens is not a problem at all, and it can even be said that this is a dimensionality reduction strike!"

He Yongbin suddenly came to his senses,

That's right, I know the camera technology myself, and it's not pediatric to go back and get a mobile phone lens.

However, the main difficulty in manufacturing mobile phone lenses has never been a problem of high-end technology, but a problem of coordination between cost and performance.

A camera can be sold for thousands or even tens of thousands,

But a mobile phone is only sold for a few hundred to a few thousand yuan, and the purchase price of the lens module inside is usually dozens to hundreds of yuan.

Therefore, the ability to control costs is very demanding.

He Yongbin couldn't make high-pixel mobile phone lenses before, mainly because of the cost, if the cost is not considered, the problem of 20 million pixels should not be big.

However, after Kangchi opened up the chip industry chain and had its own wafer factory, more than half of this problem was basically solved.

Without giving everyone much time to think, Kangchi continued to speak:

"I had a few requests for our first mobile phone lens."

"First, we don't do any secondary cameras, we just do three-lens camera modules if we do."

"Second, the pixels of the main camera and the secondary camera do not need to be too high, just control them at 1000-15 million, but the bottom and aperture must be large, and the area utilization rate of CMOS should be more than 90%."

"Third, there must be a physical stabilization system."

After listening to Kangchi's three requests, everyone present began to fall into deep thought.

It is a three-camera module, which is very in line with Kangchi's style.

The third requirement is also normal,

But the second one is a bit of a surprise.

Although as industry insiders, they also know that the image quality of the camera cannot only look at the pixels, but also the sensor size, single pixel size, aperture and so on.

For example, Pingguo's camera before 14 has always used a camera with only 1200w pixels, but the shooting quality is no worse than that of Android phones with 40 or 50 million pixels, or even hundreds of millions of pixels.

However, when almost all mobile phone manufacturers are keen to purchase high-pixel camera lenses and use them as their main selling point, Kangchi has gone the opposite way and made low-pixel lenses.

Aren't you afraid that you won't be able to sell it if you develop it?

For this problem, in fact, Kangchi has actually been thinking about it for a long time.

Anyway, with his character, he doesn't like this kind of practice of stacking up with piles of pixels, and even if there are not enough physical pixels, he uses algorithms to forcibly expand pixels.

This does nothing good other than to get a photo that is huge in size and has little improvement in quality.

In fact, for CMOS, more pixels is not always better.

For example, the price is more than 6,000, known as the micro-single mobile phone, Soni Xperia PRO-I,

Its camera uses a sensor called Exmor Rs, with only 1200W pixels, but it's one of the top mobile phone cameras, and the shooting effect can even be comparable to that of a card camera.

Therefore, whether CMOS is good or not, mainly depends on the size of the sensor, the larger the size, the stronger the light sensitivity, and the better the imaging effect.

And reflected in a single pixel, the larger the size, the stronger the light sensitivity, and the better the image quality.

This is also the reason why many people say that CMOS does not eat the process.

But in fact, it doesn't eat the process, it's just an analog circuit that converts light into digital signals.

Under the analog circuit, there is usually a digital circuit, which is responsible for processing the signal from the analog circuit, and it is very process-intensive.

If the process is too old and the signal processing speed is too slow, the picture may even freeze, on the contrary, it can reduce power consumption and heat generation, and improve the processing speed, frame rate, bitrate and so on of photos and videos.

Therefore, to manufacture a CMOS, it is usually necessary to use two lithography machines with different processes, first brush the digital circuit with the advanced process, and then use the large process to brush a layer of analog circuit.

This structure, which can be simply understood as a house,

The person standing on the rooftop of the building is responsible for receiving the light signal, and then the person downstairs is responsible for recording and organizing the data.

If there are too many people on the roof of the building standing too densely (too many pixels), and the number of people downstairs does not keep up, it will not be recorded, and it may be reported ten times above, and only once is recorded and sorted out below.

Therefore, the large bottom, large aperture, and the area utilization rate of CMOS should be more than 90%, which undoubtedly puts forward high requirements and expectations for the imaging level of this CMOS.

In fact, Suoni's Exmor RS sensor, the pixel size is 2.4 microns, according to the size of 1 inch, it should be able to achieve 2100w pixels, but it is only 1200W pixels, which shows that his actual use area is less than 60%, which is a deliberate water squeezing toothpaste.

I'm afraid of fighting with their own black card camera!

But Kangchi is not afraid, he wants to create a really easy to use high-end mobile phone lens, it can not be a numerical monster, but the picture quality must be good!
