Shu Hang wants to enter the camera industry, as the company's deputy general manager in charge of marketing, Tu Zhenying has made up for the knowledge of the camera industry, but some aspects are still not clear, after all, she must not be compared with someone who cheats.

She has actually studied all the camera brands that are slightly famous, and has actually used a lot of various cameras, and now she is even more experienced than some so-called professional photographers.

"Dual camera is the meaning of double mirror,I understand this,And I can roughly guess what it will look like in the future,But there is one thing that I can't understand,Why black and white pixels + color pixels can be synthesized to create a clearer image,This synthesis is so magical?"

"And this synthesis, I'm afraid it's not that simple!"

In the 80s, there was no talk of computer-synthesized photographs, and according to the normal development of the upper plane, new photographs composed of multiple digital photographs really appeared, which was already in the mid-to-late 90s, at this time, because there were no reliable digital cameras, and the natural industry did not make much achievements in this area.

From this, one can imagine how advanced Wang Zhengguo's scheme of using computer synthesis between black and white pixel photos and color photos was.

"That's an interesting question, and you're right on the point, about computer synthesis of photographs, which is the essence of the dual-camera solution, and that's what sets digital cameras apart from traditional film cameras. ”

The image output by a digital camera is first in the form of data, and people can post-process it through the computer, and the synthesis of multiple photos is only a kind of post-processing by the computer.

After the Republic of China sacrificed one of the four great evil arts in Asia, the PS technique, which was the ultimate in digital photo post-processing technology, and people could alter the photos as they pleased, and this magical technique must have been unimaginable in the era of film cameras.

Regarding the issue of post-photoshop processing after taking pictures, some people think that this is disrespectful to "photography", and that it is no longer a literary and artistic act that strictly records light and shadow, and that photographic photography is crazy, so that it can only make pictures that are superficial, and are no longer photographs.

Wang Zhengguo doesn't have any radical views on these, and his mind is not thinking about PS now, and the dual-camera scheme is actually contrary to the starting point of PS technology from the starting point.

One is to restore the real details of the photographed object through post-compositing, and the other is to change the original details of the object presented in the photo by means of modification and smearing, which are of course opposite to each other.

"To post-compose the photo, this is actually the processing and calculation of the data, which will involve some special algorithms, but this is not impossible, maybe because of the performance problems of the processor we are producing now, the synthesis of a photo will be delayed by a few seconds, but it is acceptable. ”

Although Wang Zhengguo's proposal for computer post-synthesis this time is a relatively advanced idea, it is not difficult to say that it is possible to realize.

It's just that I want to simply combine two photos, and I add color on the basis of the black and white photos that pay more attention to detail, and there is no change in the contour of the image, which is actually not too difficult in terms of data algorithms.

Besides, Wang Zhengguo didn't plan to hand over the photo synthesis work to the camera, which is definitely not suitable.

In the eighties and nineties, whether you were a film or a junior digital camera, it was impossible to view the picture through the on-board LCD screen as it was a few decades later, and at this time you could only use the traditional optical viewfinder to visually frame it, let alone see the photo effect through the camera's own LCD screen immediately after shooting.

And since you don't plan to equip your camera with a tall thing like an LCD monitor, if you want to see the photos you take, you can only connect the camera to the computer and preview the picture effect through the computer.

In this way, the post-data synthesis work of the image can probably be handed over to the computer to do, and the data processing power of the PC computer may not be as good as that of the medium and mainframe computers and supercomputers, but it is not difficult to do simple photo synthesis, and it is also according to the prescribed data algorithm.

Strictly speaking, in order for the early digital camera to be able to be used, it is definitely inseparable from the PC, in addition to the digital photos can be post-processed on the computer, the preview of the photo also needs to use the monitor, which has to do with the computer.

The world's first computer capable of displaying color images was not launched by Apple until '87, and although the Yaoguang 2 was planned to have this capability, it was originally planned to be on the market at least until about '86 or '87, and it would have to wait a little longer.

Not to talk about the problem of computer color display,Just talk about the image and photo preview of the digital camera,In fact, through an ordinary computer,Or the data conversion can also be done through color TV,This problem is easy to solve。

If you want to see the real photo, you can only see the paper photo when it comes out, and then you have to talk about another kind of digital camera peripherals: color printing / printing machine.

At this point in time, it was definitely quite difficult to achieve color printing/development of digital photographs, and at that time there were no color printers, and all of them were printed in black and white.

After careful consideration, it was found that in order to realize the industrial upgrading from film cameras to digital cameras, there are indeed too many supporting things that need to be matched.

Before and after, all aspects need to keep up, at least in terms of color play, Wang Zhengguo didn't think about it before, if it wasn't for this sudden memory, then I don't know when I would have to take this problem into account.

At this time, it seems that the problem restricting the digitization of the camera is no longer the camera itself, and the products that can be used can be made through the accumulation of early technology, but the photos taken by the camera cannot be output into real objects, which is a big headache.

Now is not a few decades later, people will rarely print out physical photos after taking photos, most of them are saved in digital storage devices, when you want to see, you can choose to directly open mobile phones, computers, tablets and other devices, convenient and fast.

I don't know how long I thought about it with a frown, until the hot water in the foot bath was cold, and this one spirit came back to his senses, and quickly wiped his feet and poured water.

When the footwashing water flowed into the sewer, Wang Zhengguo felt that the money invested in the camera was no different from the footwashing water, all of which flowed out in a loud stream, but due to various reasons, there was no possibility of making a profit in a short period of time.....

"Take it out, you cold feet, get out of the way. ”

It's very embarrassing to be disgusted, isn't it just that I forgot the time when I soaked my feet just now, soaked the hot water into cold water, and soaked the main feet that should be hot into a normal temperature state, and it's not a big deal.

This can't be cowardly, someone has already wrapped the quilt in warmth, he naturally won't miss it, and he finally found the opportunity.

"Oh, this is nothing, just wait a while, it's very cold outside. Moving on to business, it's still early to doze off. ”

Remembering that the previous topic was indeed not finished, this can be regarded as reluctantly accepting someone's act of "rubbing" warmth, after all, there are still steps and excuses, which is understandable.

Adjust a comfortable posture and lean on the sofa: "Let's continue to talk about digital cameras, I just suddenly remembered a problem, about the color printing of digital photos, which is difficult to solve at present, if there is no way to solve this aspect, I am afraid that it will be difficult for us to develop a market for the camera." ”

It can only synthesize photo data, but cannot output paper photos at a lower cost, which is absolutely unacceptable in the eighties and nineties, which will mean that the market that Wang Zhengguo has positioned for this camera will be lost.

At that time, although the camera can take pictures, it can only be viewed on the computer at most, which is not possible, and it is necessary to find a way to solve the problem and get a suitable color photo output, which seems to be imminent.

Looking back at the output of color photos, there are actually two major technical routes: color printer printing is one method, and digital color expansion technology developed on the basis of traditional silver salt photo processing technology is another solution.

Color amplifier in the early eighties, after the rapid popularity and popularization, and later updated and upgraded into digital color amplifier, this set of equipment is expensive, often tens of millions, so it can only exist in the professional studio of large-scale equipment.

And in fact, even after upgrading to digital color expansion, with the decline of traditional photo studios, the color expansion machine can live until 2010 years ago, once this time node is passed, digital photos are almost all changed to printing technology to output photos, no longer color expansion machine processing.

In this way, Wang Zhengguo has been the first to exclude the color expansion machine route in his heart, which is obviously something that does not have a long life cycle.

And because the early color amplifier is used for silver salt photo processing, it is naturally eyed by the major traditional image giants, Kodak, Fuji, Polyflor, Nikoca and other companies have launched corresponding product equipment, newcomers are rashly difficult to break into the field, don't go to join the fun.

The future market must be the world of color printers, and the printing of color photos is mainly based on inkjet, laser, and sublimation.

Laser color playing is not until 2000 to break through the hardware limitations, so for the time being, there is no need to consider, involving the laser subsystem, although the Foundation and Professor Wang Xuan have previously cooperated to upgrade the laser phototypesetting machine into a laser printer, but it is only a laser printing black and white image, and laser printing color images are different.

Laser printing to upgrade from black and white to color, no matter how much it has to wait until 2000 to have hope, then before that, what to use to ensure the next ten years of Shuguang digital camera photo color demand, this is the need for Wang Zhengguo to carefully consider the place.
