396: Chapter 396 The Breakthrough Challenges of Large Sensor Lenses

"I believe many friends want to scold me as soon as they hear 'Far Ahead,' saying that I've started imitating a certain big-mouth again and bragging. But before I can claim these four words for myself, I want everyone to look at a chart first."

The bullet comments in the livestream were just as Shen Fei had expected; the haters all jumped out...

"Far Ahead? I think it's 'Far Behind,' right?"

"Buy the Transsion full set, embrace intelligent radiation for your life, drive a Transsion Auto and enjoy VIP reincarnation. You all need to remember, even Shen Fei doesn't drive a transsion s7..."

"Some manufacturer is starting their patriotic marketing again. I can only say that bragging isn't taxed; otherwise, the taxes paid by this manufacturer would probably exceed those of some small micro-enterprise."

"At this point, 1/1.8 inches is called a large sensor? Samsung already had that long ago..."

Amidst their cursing, a 2014 global mobile phone industry imaging technology roadmap appeared on the big screen.

However, there was a unique line of small print under this technology roadmap.

Note: The above technology roadmap does not include Transsion Technology!

But Shen Fei didn't show this detail to the audience below; he wanted to tease those little haters.

He used the laser pointer in his hand to point to a curve on the chart: "As everyone can see, following the normal commercial rules of the industry and the sense of urgency brought to the industry by our Star Rhyme's large sensor lens... The industry still expects a 1/2.3-inch sensor to become a flagship standard in 2015. A 1/2.0-inch one will have to wait until 2016, and 1/1.8-inch? Analysts generally believe that it will take until at least 2017, or even longer, to see something that big."

Hearing this, the Transsion fans in the livestream immediately shouted "Keyboard Warriors, assemble," ready to fight those trolls to the end.

After all, with such powerful technology, why couldn't they shout "Far Ahead"?

"Damn, looking at it this way, it really is planned out to 2017. This was truly exaggerated."

"For those who just said 'Samsung already has it,' I really want to laugh. How small is Samsung's sensor? It's a full two generations behind."

"Trolls: I'm not listening, I'm not listening, it's just a PPT, it's just patriotic marketing!"

"As expected, you can shout whatever you want when you have the technology!"

After the carnival at the scene ended, Shen Fei spoke again: "But today, we have advanced this timeline by a full three years."

On the big screen, the roadmap was split by a red lightning bolt, and the transsion s5's 1/1.8-inch, super-large sensor appeared prominently at the 2014 position.

"This is the flagship main camera we built for our flagship phone. As for what kind of lenses our friendly competitors are using, we've already compared them just now, and everyone should have an idea in their hearts."

The director's close-up shot instantly turned to the audience, and many viewers turned into automatic nodding machines...

But Shen Fei paused for a moment, transforming into Lei Jun mode again, and began to explain the technical difficulties.

"Some people might ask, isn't that just making the sensor bigger? What's so difficult about that? For this question, I would like to invite our imaging department head, Wang Feng, to tell everyone the story behind this."

The spotlight hit the guest seats, and Wang Feng appeared in the close-up. Those in the livestream who originally wanted to make memes instantly deleted their jokes in the comment section after seeing this tech expert's appearance.

Wang Feng hurriedly stood up and walked onto the stage to take the microphone!

"Hello everyone! I am Wang Feng! Not the singer you are all familiar with, but a genuine technical R&D personnel. I'm here to explain the technical difficulties involved."

Familiar applause rang out again. Although Wang Feng was a technical person, he didn't have any stage fright after going up; instead, he was as smooth as a fish in water.

"This large pixel, large sensor lens actually started project initiation as soon as our project was established. The base of our first 2-megapixel lens was also very large; in fact, that lens was its verification unit!"

"When that lens appeared at the time, the entire industry was shocked because we started a domestic substitution plan, and the technology was quite good! But many people still thought we were crazy for wanting to make the sensor large while also making the pixels large."

Speaking of this, Wang Feng also smiled self-deprecatingly!

"Actually, at the time, it wasn't just the industry mocking us; even Mr. Shen said that we could set the sensor size above 1/2 inch, for example, 2.5 would be quite good, but our team is full of stubborn donkeys. Once a goal is set, we must firmly see it through... But this stubborn temper also caused us to encounter many problems."

At this time, many viewers in the audience were already immersed in learning the technology. After all, Wang Feng's speech exceeded their expectations...

In their view, what such tech experts talk about should all be professional terminology; they should be confused, know nothing, and in the end, only need to applaud and shout that Transsion is awesome...

But this process made them strangely familiar; it seemed somewhat similar to a certain friend. [Lei Jun: Still digging, what's the use of buying chips like this!]

"First, the first problem is volume, because a mobile phone is not a camera. A camera can be made very thick, but a phone cannot. Currently, the thickness of mobile phone bodies is generally around 8mm, and the space left for the camera module is at most only 6mm."

"And a 1/1.8-inch sensor, plus the lens and image stabilization module, theoretically needs to reach a thickness of at least 8mm."

At this moment, Wang Feng also took out a set of comparison lenses from his pocket. There was no such solution in our industry; he chose an equivalent substitute. They all looked very small, but under the close-up shot, the gap was still very obvious.

"This is the first problem we encountered, and it is also the biggest space challenge."

The two words appeared on the big screen behind him.

"To stuff this large sensor lens into a 6mm space, we overturned 17 design plans and redesigned the entire optical system."

"We replaced the traditional 5P lens with a thinner 6P aspherical lens, compressed the sensor packaging thickness from 0.8mm to 0.5mm, but that still wasn't enough; we even re-wound the image stabilization motor coil three times. Finally, this effect was presented!"

Applause finally broke out in the audience, and at the same time, Lan Yangyang Assistant also raised his middle finger and looked at the big screen with a smile.

He finally understood what this familiar feeling was. This was clearly Lei Jun's style... This technician is not honest! He's dissing me, Mr. Lei, again, but he really likes this style.

"If you think this is the biggest difficulty, then you are wrong, and you are very wrong!"

He took a deep breath, then shook his head!

"The biggest difficulty is the edge imaging problem brought about by the large sensor. The larger the sensor, the larger the incident angle of the edge light, which will lead to serious dark corners and a decrease in resolution."

The relevant problems appeared on the big screen behind him. Seeing that imaging effect, many viewers in the livestream shook their heads directly. This effect was too poor!
