Huawei's new patent allows the camera to zoom in 200 times. What's going on?

Photography has become a new battlefield for mobile phone manufacturers. In order to attract consumers to buy their own products, one-inch, 10x optical zoom, 200 million pixels, telephoto macro, etc., etc., are combined with each other’s own products. The camera algorithm developed by the company has made mobile phone images improve faster and faster, and many photography enthusiasts have begun to regard mobile phones as "replacements" for cameras.

But it’s not over yet , mobile phone manufacturers have realized that there is still a lot of potential for mobile phone images to be tapped. Recently, according to documents published by the relevant patent offices, Huawei has obtained a patent for mobile phone microscope technology. According to reports, when the distance between the lens and the subject is about 0.5 mm, it can magnify 20-400 times.

Public documents show that Huawei submitted this patent application in 2021, when the world was still in the midst of the epidemic. Therefore, in the patent description, Huawei specifically emphasizes that it can not only be used for ordinary photography, but can also directly identify the type and number of microorganisms (such as bacteria) in the subject, and provide hygiene advice.

Judging from this document, Huawei's microscope technology seems to be "exceeding the standard". If it can really photograph microorganisms, then what is its practical value? ? Could this be a new technology just for the sake of gimmicks?

Huawei, what new tricks are you trying to do?

According to the information disclosed in the patent, this function is completed through the main camera and the macro lens. The main camera must first be used to identify the object being photographed. and scene, and then let the macro camera access for micro photography. After the shooting is completed, Huawei will comprehensively analyze the general camera information and microscopic camera information to accurately determine the condition of the object. Finally, it will describe the object's health status through voice, text, etc., and provide appropriate health measures suggestions.

Huawei also outlines some application scenarios in the patent, including food safety assurance, kitchen utensil maintenance, personal hygiene assessment, table cleanliness, children's toy inspection, and pet hygiene monitoring wait.

Judging from the description, this patent seems to be really interesting. Nowadays, consumers pay special attention to food safety, but some harmful substances remaining on food materials cannot pass through at all. It can be seen with the naked eye that if it can really achieve a publicity effect, then Huawei's patent does have good practical value.

In fact, as early as 2021, the OPPO Find X3 series was equipped with a microscope lens with a maximum magnification of 60 times. In order to allow this microscope lens to capture more details , OPPO is also thoughtfully equipped with a ring fill light. This highly innovative microscope lens also made the OPPO Find small parts.

I have to say OPPO The microscope lens of the Find Create needs for yourself. Perhaps because of this, the OPPO Find X5 series does not retain this "creative" microscope lens.

However, many manufacturers have subsequently introduced more practical telephoto macro lenses based on the OPPO Find X3 series, which can not only take photos like ordinary telephoto lenses Distant objects can also be used as a microscope under certain circumstances. But there are still very few users paying attention to this lens.

Back to Huawei patents On this macro camera, documents show that Huawei can magnify close objects captured by the camera a full 200 times. What is the concept of 200 times? You can basically see the hairs on insect legs with a 100x microscope. The magnification of most microscopes on the market is around 180x. Only some professional optical microscopes can achieve more than 1,000x. However, ultra-high-magnification microscopes are similar to those used for daily use. The scenes don't seem to fit together at all.

The mobile phone turns into a "microscope"? It’s really unnecessary

Even if consumers are really interested in mobile phone microscopes, they can go directly to third-party e-commerce platforms to purchase microscope components that can be directly clipped onto the mobile phone camera. Although the image quality of these components cannot be compared to those of professional equipment, it is definitely sufficient for daily use. There is really no need for mobile phone manufacturers to put such a "seemingly useless, but actually even more useless" function into mobile phones. , not to mention the image that today’s consumers are most concerned about.

Even if some netizens really say that they need a microscope function, it is impossible for mobile phones to replace it. For example, the imaging of a traditional stereo microscope is from the eyepiece. The three-dimensional feeling you see inside, if you switch to a mobile phone to watch it, you will lack this three-dimensional feeling, because the mobile phone simply magnifies, even if it is digital amplification through software algorithms, it is completely inferior to what can be achieved through optical structures. of amplification.

Of course, Mobile phone microscope technology is still facing many problems, such as how to minimize the size and space of the lens while ensuring the shooting effect. After all, the space inside the mobile phone is very "valuable"; how to implement the microscope camera and The perfect integration of the camera; and how to lower the threshold for getting started so that ordinary users can easily get started with it. These are all problems that mobile phone manufacturers will face. If these problems are not completely solved, they will only end up with a tasteless semi-finished product. .

But no matter what, mobile phone manufacturers are right to be willing to innovate. The mobile phone industry has developed to this day, and even mid- to low-end mobile phones can have good image performance. , some highly innovative manufacturers have begun to make fuss beyond optical lenses. It is foreseeable that in the next few years, this kind of non-traditional optical lens may be increasingly installed on mobile phones and become a new innovative symbol of mobile phones.

The persistence of mobile phone pixels Improvement, the continuous increase in the number of cameras, and the continuous optimization of photo effects are all inseparable from the continuous breakthroughs and innovations of countless engineers. It is the efforts of these innovators that allow us to press the shutter of our mobile phones at any time to record the beautiful moments in our lives. Come down.
