To what extent can a 100x zoom phone achieve? “IT Times” reporters tested in a number of actual scenes and found that the 14-story building was “peeped”, the QR code was “stolen”, and the smart door lock was “cracked”. It can be done under certain conditions.

When the 100x zoom becomes the standard configuration of future flagship phones, when the black-produced telephoto phones are converted into illegal cameras, and when criminals insist on peeping, we should be alert : There are “eyes” in the window, and people are peeping through the mirror, and what is peeping is privacy, but what the lens reflects is human nature.

A man who broke his leg, staying at home, doing nothing. He used a camera to spy on the lives of his neighbors. The camera recorded the actor practicing dance, the pianist who opened the party, and the murder of his wife. This is the plot of Hitchcock’s 1954 classic thriller film “Rear Window”.

Although the male protagonist assisted in solving the murder case because of voyeurism, his behavior is full of controversy.

66 years after the film was released, the topic of private voyeurism is still receiving attention, and the technology that should have been neutrally developed may become a “surprise artifact”.

In 2020, Samsung, Huawei, and Xiaomi have successively launched mobile phone products with 50x or even 100x zoom and above, which means that users can see more details that are invisible to the naked eye.

What does one hundred times zoom mean?

At station B, an UP owner used the 100x zoom function of a Huawei P40 Pro to photograph a hotel logo two kilometers away from home. The Wall Street Journal also did a test. A Samsung S20 Ultra phone with 100x zoom can capture the clear face of the user by the window on the 4th floor across the road from a car 15 meters away.

When the voyeuristic purpose is coupled with a mobile phone with a 100x zoom, the hidden worry is already there.

“IT Times” reporters used multiple high-magnification zoom mobile phones to detect multiple scenes in shopping malls, convenience stores, communities, etc. and found that ordinary people are likely to encounter privacy leaks and mobile phone QR codes due to “distance” peeping Potential threats such as stolen accounts and cracked smart door locks.

Be careful, there are “eyes” in the window.

Tested by the reporter: What can the 100x zoom do?

Standing on the 14th floor, “I” can see what you are eating

In the dark night, the camera keeps advancing until the movement behind the glass window becomes clear. A Korean couple “candidly” meet each other. The hero and the heroine did not notice that their every move is being recorded by a mobile phone.

On a foreign website, the video has been viewed more than 600,000 times, and there are still many similar pornographic videos that are secretly shot with a zoom phone.

How powerful is a high-zoom phone?

In a commercial plaza in Shanghai, the reporter did a test. Standing on the 5th floor, the tester on the first floor was photographed with a Huawei P40 Pro. When the lens was magnified to about 50 times, his outline was clearly visible. Although the reporter reminded the tester that he would shoot on the 5th floor before the filming, the other party did not find the location of the lens after searching.

This means that it’s difficult to be known when the person who is taking pictures is far away from the victim.

During the test, security guards walked past reporters from time to time in the mall, but mobile phones were not as conspicuous as SLR cameras. The security guards did not pay attention to reporters who manipulated the phones.

If the lens is magnified to 100 times, how good will its eyesight be?

In front of the 14-story window, the reporter placed a tripod. The Huawei P40 Pro on it was aimed at the tester on the opposite side of the road. The distance was about 60 meters in a straight line. After zooming up to 50x, the eyes behind the lens can clearly see what the tester is eating, a few skewers on his hand, and various expressions when eating.

When you think your surroundings are safe, a high-zoom mobile phone may break your imagination, and you don’t know anything about it.

Six or seven meters away, “I” can steal your mobile payment code

Obviously, the QR code was not opened, but the phone showed the consumption amount reminder!

An IT Times reporter conducted another experiment outside a convenience store. At a distance of 6, 7 meters, the reporter’s payment QR code was “candidly taken” with a zoom of more than 50 times, and the photo was successfully recognized by the merchant’s code scanner. If you “candidly photograph” the tester’s mobile phone on the second floor of the mall, the picture is even clearer.

The update time of Alipay and WeChat QR code is 1 minute, which means that within one minute, if your payment QR code is “sneak shot” and you set a password-free payment, there is a risk of being stolen. .

A reporter from “IT Times” checked WeChat and Alipay related agreements and found that the maximum amount of confidential payment is 1,000 yuan.

This may not be the worst. Standing at a corner 4 or 5 meters away, a tester entered the smart door lock password. Although the screen was a bit jittery, the “sneak camera” could still calculate the door lock password based on the action.

Your actions will be recorded by the “eye” in the distance. Similarly, you are ignorant of this.

In-depth reading: Anxiety behind 100x zoom phones

Aim Huawei P40 Pro at the moon, zoom to about 80 times, and the moon fills the entire screen. This means that even if you are sitting at the farthest point of the concert and looking at your “idol” (idol), you don’t need to use 100x zoom .

“What is the significance of the so-called 100x zoom of the mobile phone camera?”

Under the knowledge of this question, one of the most praised responses said, “It’s full of gimmicks. This is a focal length that professional photographers have not used for 800 years.” But a highly praised answer said “100 The value of multi-zoom is not that professional photographers cannot use it, but that it can greatly facilitate people’s lives and liberate productivity.”

Flagships will popularize high-magnification telephoto

“There are not many scenarios where 100x zoom is actually used.” Sun Yanbiao, Dean of the First Mobile Phone Industry Research Institute, told a reporter from IT Times.

In his opinion, in the context of not optimistic sales of flagship phones, various mobile phone brands need to innovate, and they need to be inexpensive, and the user’s sense of innovation is obvious. The telephoto lens just meets this demand. This is also the mobile phone. The origin of manufacturers launching high-zoom phones.

The periscope lens is the main element to achieve clear and long-distance zoom. Traditional cameras adjust the focal length by changing the lens distance, but the mobile phone lens cannot be pushed or pulled. The periscope lens uses the principle of prism reflection to achieve optical zoom on the mobile phone camera lens, even taking into account the limited thickness of the mobile phone.

If you compare the digital zoom of traditional mobile phones, the image quality of the periscope lens is also higher, because the former is essentially just taking high-pixel photos and continuously zooming in and cropping.

Starting from the second half of 2019, Huawei, Samsung, vivo, and Xiaomi have successively launched flagship phones with periscope lenses, and the zoom distance is getting longer and longer, 20 times, 30 times, 50 times, and the latest 100 times.

According to data from Huaan Securities, taking Huawei P30 Pro as an example, the entire rear four-camera module including the periscope lens costs about 65 to 75 dollars, of which the price of the periscope camera is about 20 to 30 dollars. Including prism 2-3 dollars, lens 2-3 dollars and so on.

The relatively low cost of innovation and perceptible changes have made periscope lenses popular in high-zoom phones.

Sun Yanbiao predicts that after September this year, periscope lenses will become the standard equipment of high-end flagship phones of various brands. According to Huaan Securities, the shipment of mobile phones equipped with periscope cameras is expected to reach 100 million units in 2020.

The hidden worries that can’t be erased by the black property

In February this year, Samsung released the S20 Ultra mobile phone. This promotion features 100x zoom and 100 million pixels. This is also the beginning of a 100x zoom mobile phone camera.

A senior IDC researcher told the IT Times reporter that she was very upset at the press conference. “You absolutely don’t want your weird neighbor to have such a mobile phone.” She is afraid that her privacy will be invaded.

Privacy space is her life and work.

The “Wall Street Journal” reporter once did a voyeuristic test in a work setting: In a cafe, a private investigator clearly photographed the sentence typed on the reporter’s computer screen at a distance of 5 meters, “I know You are peeking at me!” This may also be the silent resistance of the reporter.

A netizen was on the plane two rows away and photographed a document being revised by a passenger. Even the annotations on the pencil were clear. Although this netizen said that she was not a malicious voyeur, the phone camera made it difficult for her to restrain her “curiosity.”

After Samsung released the S20 Ultra, the British “Daily Mail” published an article saying that it was worried that some users would misuse this technology to do some evil things, such as peeping at someone’s bed and desk from a distance, but the article revealed helplessness.

In April of this year, the vice president of Xiaomi Group Chang Cheng made improper remarks on Weibo, describing the 50x zoom phone of the Xiaomi Mi 10 Youth Edition as an “artifact for peeping at the crotch of a boy on the basketball court and the dormitory of a girl on the opposite side.” Aroused public opinion questioning.

However, after the turmoil subsided, worries fell silent again in the online world.

In the Huawei Pollen Club, many netizens said with a smile not to use the P40 Pro 100 zoom function to spy on others. Behind the joke, they realized the potential risks.

The difference from the forgetful public is that the desire for private voyeurism is surging, and the black industry is ready to move.

According to the law, the production and sale of micro-cameras, pinhole cameras and other secret photography equipment are illegal. Such goods on e-commerce platforms are prohibited goods. However, in the black production circle, some sellers are providing modification of telephoto phones Service, buyers can use it as a substitute for miniature cameras.

“Don’t worry, the original lens function can still be used, and you can see it at long distances and close distances!” A seller offered a quote to the reporter, charging 3000 yuan for a pinhole camera on a Huawei P40 Pro, and the modification The price of a P30 Pro is 1,500 yuan. Another seller advertised that if you are not assured, the cost of modification can be paid on Xianyu, Zhuanzhuan, and confirmed after receiving the goods.

The mobile phone camera was supposed to record a world of light and shadow, but it was off track due to the desire for voyeurism.

Reporter’s Notes: A mobile phone that sees the world clearly, a lens that magnifies desire

During the test, the reporter repeatedly asked himself: Is this something that needs attention from the whole society?problem? Are we awake or abet?

But in actual interviews, the answer became clearer and clearer: The malicious use of tools is not non-existent, but hidden under the iceberg. We need to let these hidden risks surface.

In May of this year, the OnePlus 8 Pro mobile phone was equipped with an infrared photosensitive camera for its rear camera, which caused controversy because it can see through objects to some extent. Eventually, this feature was stopped.

Nowadays, periscope lens and high-zoom mobile phones are gradually entering people’s lives. When they become “eyes” better than human eyesight, the probability of being used badly increases greatly. After all, who would pay attention to a person playing mobile phones What?

So, what can we do in the face of possible voyeurism?

Paste a layer of privacy film on the phone, cover your fingers when entering the door lock, and draw the curtains in the room… Don’t forget that there may be an “eye” out of reach of human eyes.

Some people may say that such precautions are a bit pessimistic, and even some are groundlessly worried.

Many people are willing to believe that technology is neutral in nature, but in fact, technology amplifies human desires. Corresponding to the illusion of seeing the world clearly, there may also be trouble, loss, and injury. When criminals are obsessed with voyeurism, technology begins to be hostile, and it will bring scars to some people’s lives.

Foucault once proposed the panoptic theory, the core of which is that if a prisoner is kept in a transparent and visible prison, he (her) will realize self-discipline because of fear of being monitored. Similarly, in the information age, more and more convenient peeping tools (whether mobile phone or camera)The monitor outside the view glass window can invade the private space of an individual, and it can also spy on the actions of ordinary people from a distance. Once people realize this, they will no longer have inner freedom. People are passively accepting the arrival of “panoptic”, regardless of curiosity or malice in the peeping.

Is there a solution? The reporter did not have a good answer until the operation of this topic was completed. In order to prevent sneak shots in South Korea and Japan, iPhones sold in their home countries must have a shutter sound when taking pictures, but this restriction has no effect when shooting at long distances.

Looking back at “Rear Window”, there is a high praise comment on Douban: If the police find that the murder case is not established at the end, this film will have a better ending.

There are “eyes” in the window, and people are peeping through the mirror, and what is peeping is privacy, but what the lens reflects is human nature.
