In the end, it is still a black and white pixel CMOS pattern sensor, no wonder it can make an engineering prototype so quickly, this thing is much simpler in terms of technology, and it is completely understandable.

What really makes Wang Zhengguo unbearable is actually the picture displayed on the computer screen, no, it really makes people cry and laugh, although I can barely see a little rough, it can be determined that it is Wang Zhengguo himself, but the super clear mosaic really makes people unbearable.

This is probably the first ever digital portrait photo with a mosaic, and it seems that someone has successfully won a world record, and I am afraid that I will be pointed out by thousands of people in the future!

"This ...... What's the situation, and why is it so vague?"

In memory, as long as the pixel of the photo is not too low, it will generally not be blurred to the mosaic level, only this time, Wang Zhengguo's three views have been refreshed again.

Also embarrassed is the professor himself, he thought that his work could have a good imaging effect, but he never expected it to end up like this, shame!

Hurry up to find the reason: "This image blur problem, generally caused by a variety of situations, we are only through the engineering prototype to show whether the design is feasible, the design is not too high in the pursuit of image quality, the follow-up will immediately start to improve." ”

For the problem of photo quality, the common ones may be those three, or break them one by one.

"First of all, the sensor itself, due to the equipment limitations of our school, even if I used a larger area sensor design, the pixels are still only 100*120, that is, 12,000 pixels, this data is definitely not enough, so the picture blur is an inevitable event. ”

The number of pixels of the CMOS pattern sensor, which is most directly affected by the production process, without a good production process, it is absolutely impossible to make a high-pixel sensor, limited by the hardware level of the school, which is not solved in a short time.

Restricted by the level of technology, at this time, even Ni Guangnan, who is engaged in different fields, can only sigh silently, now the domestic technical level is already backward, not to mention the university hardware that is generally behind the top equipment level in China, there is indeed a gap.

"And then the photo is enlarged by the monitor, and in fact, we use the standard photo paper size to determine the sensor size output design, and if it is really printed on a four-inch photo, it may be much clearer. ”

Digital photos are blurred due to over-enlargement.......

Well, this is also a reason, but none of the above is obviously enough to blur a photo into a mosaic state, and Wang Zhengguo really can't figure it out.

"What is the last reason, I'll listen to it, the first two are not enough to directly cause the photo to be pasted like this, and the real reason is definitely not the case. ”

In fact, at this time, several people in the laboratory saw the real problem, including Wang Zhengguo, but he didn't say it, it was best to let the professor say it himself at this time, and someone could do a wave of good things in the future.

Pointing to the only computer in the laboratory: "The problem is here, the graphics processing technology that processes the digital signals of the CMOS sensor, we choose computer software to process the image compositing, which is why the photo loading speed is very slow, as for why it is blurry, it is mainly an algorithm problem, our algorithm is still too simple, there is no refinement at all." ”

No matter how capable Professor Bai Siwen is, but he is only doing hardware design, and he really wants him to do graphics processing algorithms and optimize the best results, which is embarrassing for others, and he really can't do it.

He turned around and beckoned the young assistant next to him to come over, and introduced with satisfaction: "My main energy is in the research and development of CMOS hardware, and the software algorithms of this part of image processing are all done by my student and assistant Yang Zhipeng. ”

Okay, it turned out to be not Professor Bai Siwen's own product, so it's not good to say anything more, if this paste problem is in the software that Professor Bai Siwen personally asked, of course, you can say a few words, but now with a young student assistant, the original problem is no longer a problem, and it has even become a good thing.

The young man who was introduced was obviously a little shy, and sure enough, he was still an engineering student, it was really a familiar atmosphere, not bad, worth cultivating!

There is no need for Wang Zhengguo to speak, Ni Guangnan learned that this young man had developed image processing software, and he was overjoyed, this is simply a talent, an absolute potential talent.

"Solving the conversion between binary data and images requires a variety of algorithms, among which the ...... are compensated"

"This was really a big problem I encountered, and then through multiple calculations, I adopted ......"

Okay, I have to admit that I don't understand this, but Wang Zhengguo is very satisfied, he can also see Ni Guangnan's attitude towards this young man, it really doesn't have to be picky, and several professional questions before and after have been answered smoothly, which is right.

Turning around, he gave the results of the investigation as if he had found a treasure: "Very good, this young man is very talented, not only excellent in software programming, but also talented in the field of mathematics, which is difficult to encounter in China, so he was born to be a high-end talent for image processing algorithms, and this time he is it." ”

Except for Wang Zhengguo and Ni Guangnan, the rest of the laboratory doesn't understand the situation, what's going on?

"Professor Bai, let me introduce first, this is a return from studying in Canada, the former senior researcher of the Chinese Academy of Sciences, this time invited to join Yaoguang Electronics as a hardware chief engineer, we consider to give the 6502 computer a laser printer, we need to be able to do digital image processing and computing related talents, after comprehensive consideration, I think your assistant is good, his talent can meet the needs of the future. ”

Even the assistant himself hasn't said a word, but this does not prevent the bigwigs from arranging talents, at least Bai Siwen is reluctant in his heart.

"Are you going to transfer Yang Zhipeng? I'm afraid this is a bit difficult, now my whole team can do digital image processing alone, and I have also seen that now this software is really unusable, and he will have to optimize it in the future, so ......"

To let yourself go, of course, it is impossible to agree so easily, this is the whole team currently can't find a replacement key person, nothing can be poached, now is the critical moment of the project, there must be no leakage.

It's clear that it's not a rhythm to let go of people, so it's obviously a misunderstanding, and it's not that you don't want to continue to do image processing technology, but now it's just a separate pull out, and you have to pay more attention to and cultivate.

As the chief hardware engineer of Yaoguang Electronics, he must stand up at this time: "Professor Bai don't worry, we transferred Yang Zhipeng out to do image processing technology, also in order to develop better, after the follow-up technology is made, it can be directly used on your digital camera, and the technology will only be better!"

Now Yang Zhipeng is using software to process images, and before Yan Yuanchao used CCDOS to realize the computer's Chinese character display, there are similarities, although the technology is feasible, but as long as the corresponding technology is transplanted to the board, chip, its technical level can be on a higher level, just like the relationship between CCDOS and Hanka.

Considering these, Ni Guangnan rightly thought that he should come forward this time and take Yang Zhipeng into his hands. 10
