"I'll see!"

Hearing this, Atletico Madrid threw the square cylindrical object in his hand to Tang Jiayi, who had just swam around from the sea water and was going to go ashore to rest, turned around and sat on the beach chair next to Atletico Madrid, and at the same time reached out and pulled a gauze towel to cover her abdomen. ：.――.／

After changing a comfortable position, Tang Jiayi looked down at this strange thing.

It looks like a square lipstick box, but the shell size is larger using aluminum alloy and rubber splicing, the aluminum alloy part is the lens group, the top is a round lens, the rubber half is the battery and circuit, and the bottom is installed with a less than two-inch LCD touch screen as a viewfinder, next to the Lytro logo. There's also a USB port, a power button, a shutter button, and a touch slider for adjusting the built-in 8x optical zoom lens.

The overall design is simple and impressive, but it just doesn't look like a camera.

The Lytro light field camera, which was launched in February, claims to have patented light field camera technology, which can save the color, brightness, and direction information of 11 million beams of light entering the lens, and then use software algorithms to "take a picture before focusing", and even adjust the angle of view and directly convert it into a 3D photo.

It looks beautiful, but the actual use effect is a bit hehe.

Tang Jiayi took this square barrel camera, confirmed the position of the shutter button, clicked a photo on the beach, and then lowered her head and swiped down on the touch screen for a long time, and finally frowned and asked: "Why didn't you see the focus function after taking a picture?"

"It seems that the light field analysis algorithm is too cumbersome, and it can only be operated on the computer with client software. ”

"Well, that's not interesting!" she handed the camera back to Atletico Madrid, while expressing her disapproval.

"Actually, the concept of the light field camera is still very good, some close to the concept of holographic photography to collect all the information with one click, but their final product is a bit of a trick," Atletico smiled and sent the camera to the side of the frame, he was still very relieved to see that the competitor's products were not good.

The concept of light field photography has been proposed for 100 years, as early as 1908, the French scientist who won the Nobel Prize in Physics for the first color photo in human history, Gabriel Lippmann, proposed a device called "integration camera", but just like his "natural color photography technology" that applies light wave interference technology, this structure is too complex "integration camera" has not finally been put into practice, and there has been no practical light field camera product for nearly a hundred years.

It wasn't until 2006 that Yi-Renng, a doctor of computer science from Stanford University and a Chinese-American American, developed a truly practical light field camera product.

Of course, even if it is practical, the experience of using the Lytro camera is still not good enough, and it is maddening to use the accompanying software to edit and adjust the photos just by connecting to a Mac computer after taking a photo.

Perhaps before the popularity of digital cameras, users of film cameras could still accept this kind of "post-production" gameplay, but now that film cameras have been completely eliminated and portable card digital cameras have been eliminated by camera phones, the lytro camera that cannot "see is what you get" will definitely be less attractive because of this shortcoming, at least Tang Jiayi, who is used to taking selfies with her mobile phone, has shown her disinterest with her actions.

"But that's just right, since you don't give us face, let them play with the mud!"

"Belly chicken intestines!"

Long before the Lytro camera went on the market, Atletico noticed Wu Yiren's doctoral theory, and tried to recruit the other party, but although they also have names, but Malaysia was born and raised in Australia, and the latter who went to college in the United States did not have much in common with Atletico Madrid, and at that time Atletico was just an ordinary undergraduate student in the computer department, and there was no achievement in either the business or academic circles, so naturally the recruitment failed.

When Atletico had the money, the latter also founded his own Lytro company and brought in $50 million in venture capital, although the VCs didn't mind Atletico buying the company at a high price so that they could make money to exit, but the premium must have been quite substantial, so in the end it was gone.

Since the recruitment failed, Atletico also began to study Bee's own light field photography technology, that is, the array camera system applied to the large dragonfly drone.

In fact, because of the extremely high demand for the "post-production" software processing part of light field photography, several similar companies in the world were almost established around 2008, and they are inseparable from powerful GPUs, the difference is only in their respective lens organization models and corresponding algorithms.

Lytro puts a micro-lens array between the main lens group and the C-Touch S image sensor, and another German company, Rayt X, also uses a microlens array, but it is more complex and uses three microlenses with different focal lengths at the same time to obtain more accurate light information, which has the advantage of higher final image resolution, but the corresponding cost and price are also greater. While the former's first camera sold for $399/$499, the latter's industrial-grade lightfield camera sold for a whopping 20,000 euros.

The biggest advantage of the microlens array solution is that there are few changes to the camera's structure other than this microlens, but because each microlens is imaged on the C-Map, the final output of the effective pixel count is limited by the number of microlenses, and is far more than the resolution of the C-Map. For example, the Lytro camera bought by Atletico can capture 11 million rays of light on the book, but the actual output of the 2D picture resolution is only 1.2 million pixels, and the more expensive Rayt Day X can reach 2.7 million pixels, which is still very bad compared with the mainstream digital cameras that have already entered the 10 million mark.

The number of microlenses cannot be increased indefinitely, because increasing the density will cause the light passing through the lens to diffract because it is too close, so some people have thought of another more "traditional" idea, that is, to use a large number of microcameras to form a structure similar to the compound eye of insects, each micro camera has its own lens and imaging module, which are precisely fixed with each other, and the image obtained by software synthesis is synthesized. For example, the dragonfly camera of bees and the insect eye lens array of Peliimaging, another American company, are all chosen for this solution.

Although it seems that a dozen or even more lenses are densely packed together like a lotus canopy, in fact, the bee dragonfly uses only a "pseudo-light field", which emphasizes the ability to quickly focus and chase the focus in a wide range of motion imaging, after all, it is equipped with a drone flying in the sky, and the flaws such as distortion and partial blur of the actual imaging have not been solved, and the photos and videos taken by the dragonfly often need to be retouched for post-production.

So Atletico has been worried about "Li Ghost meets Li Kui", when the Lytro camera was officially released, he immediately noticed it, even during the honeymoon vacation, he did not forget to buy several, dismantling and analyzing it while personally trying it out, confirming its actual use effect and assessing the degree of threat, now it seems that he can rest assured for the time being.

Ma Jing took out two bottles of drinks from the refrigerator on the table and handed one to Tang Jiayi, opened another bottle and took a sip with his head up, and then said: "In fact, this kind of technology of taking pictures first and then focusing is still very valuable, no matter what aperture focal length shutter time it is, as long as there is a similar composition and then click to capture the picture is OK, the adjustment of various parameters is automatically completed by the software, and it is made into a point-and-shoot camera in the DC (digital camera) industry, I believe there will be a lot of photography painstaking people who like it." And now that DC is in decline, mobile phones have taken away the seat of pocket cameras, and this technology should also be used on mobile phones. As a result, they went their own way, releasing such a toy-like digital camera, and the experience was not the best. ”

"Well, that's it, I just pressed the shutter and found that I had to wait a few seconds to continue to take the next picture, which is too troublesome, and the LCD screen resolution is too low, and there is no wifi or OTG, you need to see the big picture and have to read it on the computer, which is also too troublesome!" Tang Jiayi couldn't help but complain.

"And it has to be a Mac. ”

After looking down and thinking for a while, Tang Jiayi hesitated and said: "Maybe they launched this generation of products just to prove their technical strength, and they still have to do it on mobile phones in the future, right? Wasn't Jobs also very interested in this technology last year?"

"Maybe," Atletico reached out and grabbed the Lytro camera from the frame and shook it, "but if their lens group was still so thick, neither Joe Gang nor Cook would let it be on the iPhone, Apple has always been a pioneer in design but not technology, and rarely preempts the most fashionable technology." Trendy technology means imperfection, imperfection, and high cost, which is not in line with Apple's style. ”

"By the way, I remember that the dragonfly drone's electronic compound eye focusing speed is very fast, and you can quickly focus on the mobile phone screen with a casual click, why not use this technology on the mobile phone?"

"I want to too!" Atletico raised his head and poured the rest of the drink, "but the so-called fast focus of the dragonfly camera is actually a quick switch of the main signal, there are dozens of cameras with different parameters on the dragonfly, each with different orientations and focal lengths, this kind of focus is actually like a person switching the left and right eyes, directly switching the image data of different cameras, of course, the speed is fast." However, in this way, the number of cameras cannot be less, and it is not good to put it on the mobile phone to occupy a large area, and it may be called a spider. ”

After thinking about it for a while, Tang Jiayi couldn't help laughing out loud when more than a dozen round black pitch lenses were densely installed on the mobile phone: "Haha, maybe someone is just right for this? After all, there are many people who raise pythons, lizards, and spiders as pets these years?"

"Hey, forget it, it's too beautiful for me to let it appear. ”

"By the way, Dao Dragonfly Drone, it seems that you have done something big recently?" Tang Jiayi straightened up and turned to look at Atletico Madrid, staring at him without blinking, waiting for his explanation.

"It was an accident, an accident! It's a pure coincidence, okay!" Atletico Madrid said with a "face full of grievances": "I didn't expect that Gou Li's psychological quality was so poor, and he was easily frightened out of the truth, if this guy is properly seen in the war years, he will be a traitor and traitor!"

"Oh, what's the matter?" Tang Jiayi's gossip soul instantly erupted, and she asked kindly.

She only saw a message through the Internet, it was the Ludao police, with the cooperation of the bee group, caught a criminal who used the bee dragonfly drone to engage in burglary, and found out a mysterious list from that person that was enough to overturn many provincial officials.

"That Gou Li is a thief, and he is also a self-taught drone expert, in order to facilitate stealing with drones, he has invented a lot of special pendants. Then I found out about it because of some channels, and I wanted to recruit him. However, this man was very cautious in his activities as a thief, so I used some means to fool him to the Egret Island Bee Garden. ”

"It didn't work out, when he went to the bee garden that day, there happened to be a team of patrol police tea resting and drinking tea in the guard room, and then he saw several big caps sitting in the guard room and suddenly shook his head, turning his head and running!" Ma Jing sat up and waved his arms to make a running posture: "Then naturally, this person's behavior is so suspicious, thousands of drones are not needed, those patrol officers know that there must be something on him, Hula pounced and pressed him to the ground." ”

"That Gou Li is also an emotional intelligence that needs to be recharged urgently, and he directly said that he is willing to confess and strive for meritorious service, because he has black materials from several other city cadres' departments, what is hiding a large amount of cash at home, and there are improper relationships between men and women with several people. ”

"Then I don't know who revealed the list, and it was reprocessed, and it is estimated that the person who forwarded it disliked that there was not even a single place on the list, so they were promoted to a few ranks. In fact, those guys are all officials and civil servants who live in ordinary districts, after all, there are guards and even armed police at the gate of the real family home, and he can't get in with a stranger at all. is also because they are all people, and the Egret Island side did not cover it and directly reported to the local area, and the people who did the work were also careless and troublesome and directly sent the entire list in groups, which is estimated to have led to the leak in this process. ”

"That's it?" Tang Jiayi asked unsatisfactorily, this "truth" was too simple and pale, she didn't want to believe it, "By the way, that Gou Li has two ID cards, and you haven't seen him, how do you know?"

"Alas, don't mention it, I can't figure out how this guy can get away with it for a whole year!" Atletico stretched out his finger and pointed to his face, and said with hatred: "Although that guy has two ID cards, he has a bee account bound to both ID cards, and when he does identity authentication, he does video verification, and the system almost merges the two accounts with the same item!"

"Hahaha!" Tang Jiayi's face bloomed with a smile, "This guy's IQ has to be recharged!"

"No!" she suddenly stopped laughing, frowned and asked: "How did I smell the smell of conspiracy, the patrol officer often goes to the guard room to rest and look at the big screen by the way, you should know about this, why did you specially ask him there?"

"Well, I just wanted to fake the fox and take advantage of the situation to make a price, who would have thought that he would be so careless! Hahahaha laughed at me http://m.piaotian.net!"
