The first 200 million pixel mobile phone is here. Do we really need 1 100 million pixels?

The first 200-megapixel mobile phone is coming. I think it is necessary for us to have a 1 megapixel mobile phone. Different industries have different requirements for pixels. Mobile phone is a product that is updated quickly. Only better products can make technology move forward, so I think it is necessary for the following reasons:

In many people's minds, taking photos with a mobile phone is a dispensable thing, because the photos he takes are ordinary, not as unexpected as taking photos with a mobile phone. About Xiaomi 12T series products, two models, Xiaomi 12T and Xiaomi 12T Pro, were mentioned this morning. It is said that it is the first 2-megapixel mobile phone (there was only one 200-megapixel mobile phone before) and will become the first 2-megapixel touch-screen mobile phone in the world. ?

As we all know, mobile phone lens is a high-precision component, which mainly includes many key components, such as pixel sensor. Does it mean 1 100 million pixels, or is it only 1 1.7 inches up and down? Actually, it's not like this. Let's take a small-screen flagship mobile phone to talk about its creative background! Although it is only 1 1.7 inches, it still has amazing photo effects, and it can take photos with 20 million pixels, and sometimes even clear photos! Over the years, people have been pursuing the practical effect brought by 1 1.7 inch photos, and some even think that high pixel is to better record the beautiful things in life. So let's talk about why the phone lens is so big. What determines life?

First, why do you want to use the mobile phone lens as a precision component on such a large scale?

We all know that there are many kinds of camera lenses used in mobile phones. In addition to the conventional12 million pixels and 20 million pixels, there are also small pixels of various sizes, such as10 million,18 million, 200 million pixels and 200 million pixels. For example, the two billion-pixel mobile phones announced by OPPO this time are also 1 billion (in ms). How can such a high Cpu and its display screen have such requirements for taking pictures? Let's take a look at the characteristics of the camera on the mobile phone. First of all, in normal mode, a mobile phone can shoot 960720 clear video or 120fps high-frame video to be a high-end flagship.

But under normal circumstances, the camera can't take such a small video or a high-pixel photo. And the more pixels there are in the camera, the more scenes you can get. The surveillance camera with 65.438+0 billion pixels can shoot 64 million pixels when taking pictures, which seems to be very high. However, it still needs to be equipped with 6,543.8 billion pixel sensors, a picture with 4 times optical zoom performance, a laminated glass camera lens with 2 times electro-optical zoom ratio and multiple sonyIMX586 sensors. Therefore, in order to better meet people's requirements for the quality and speed of taking pictures in daily life, it is necessary to increase the specifications of the surveillance camera by 20 million or even 65.438+0 billion pixels, or take photos with more than 64 million pixels. ?

Second, at this stage, the mobile phone camera function has not stopped in the field of mobile phones, and has been trying to provide users with a good camera experience on mobile phones. ?

However, this demand has always existed. For example, some flagship models can already provide three or even four ways to take pictures. With the improvement of technical strength and functions of mobile phones, the mobile phone industry is also advancing with the times. At this stage, there have been many ultra-high-end flagship models in the smart phone market. For example, OPPOFindX2Plus can not only complete the built-in 3-camera function, but also shoot 4K short videos. ?

In addition, models such as vivoNEX and OPPORenoRs can also shoot 4K short videos. If you are interested in taking photos with your mobile phone, you can continue to look down at this picture. 40 cm, 40 cm large-size display screen, the display screen size is reduced from 6.0 inches to 6.3 inches. In this picture, you can see there are many function buttons on it. It mainly includes two function keys: long press and short press. Click function is used to bring up multiple tasks. The short press function is used to switch between the screen and the camera mode, and its camera time setting buttons are used for camera time and audio time respectively; You can also set camera parameters.

? Third, is the pixel height good?

Studies have found that photos within 1 100 million pixels will be clearer and sharper than photos above 300 million pixels. In essence, 1 100 million pixels is equivalent to 1 black and white pixels per inch, so it can be said that the development quality is very high. Of course, this figure is extremely low, just in the middle of 1 1.7 inch. In that case, if calculated at the level of 1 100 million, then this figure is equivalent to the effect of 1080P that we often see now. Moreover, this number is not a short board for taking pictures, because it directly affects the actual effect of mobile phone imaging.

For taking pictures, high quality is the most important criterion. Only when we first realize the actual effect of taking pictures, will everyone gradually like and rely on this shooting method. The key of notebook photo function is to record what happened in life. At the same time, as an electronic product, we have to make some special upgrades and changes on the mobile phone, so we will see more and more models add more built-in performance and monitoring cameras, such as rear camera, dual lens and night scene shooting. In addition to improving the performance of the system software and the actual effect of taking pictures, it can also change various details of everyone's daily life at present. For example, some people are used to jogging in the community recently. If a car runs slowly, there may be many problems such as wheels being rubbed and passers-by falling down.

? 4. What is the function of hundreds of millions of pixels?

In fact, high pixels are to better record our own lives and beautiful things. On the photo page of our notebook, each subject will be marked in detail, and the specific content is actually the head of each of them. When we want to take this portrait with our mobile phone, we will record the different expressions of each of them and then generate a delicate image. In addition, there are some places that will indicate how many people are actually in this subject and how big it can be compared with others. These data can be recorded and saved. Even many people used photos to record the portrait of a designer who had been to the scene or heard of it.

When we take pictures, the camera of the mobile phone will automatically record the portrait pictures they took. But from another point of view, we also think that these headshots are our own headshots, which show the best day we have experienced or what we want to record. With these characteristics, people will even record the cities they have been to and unforgettable people and things, and some even compare these people or things with those around them to show how different they are from these people and things! It can be said that it is very practical to take photos and record them with a mobile phone. ?

What does this mean for hundreds of millions of pixels? Is the mobile phone running memory?

5. How to improve the performance of mobile phone photography?

The key lies in the processing chip. For SLR cameras, the camera module of the notebook is used to enlarge the surveillance camera, not to take pictures. At this time, it is necessary to do more upgrades on the processing chip. To a certain extent, this will put forward higher requirements for the camera performance of notebooks, which is why 200 million cameras should be used.

Of course, because the size of the surveillance camera is also exquisite, you need more rechargeable batteries to ensure the application. Then the ISO is raised to 1 1.7 inches. 1 1.7 "corresponds to 20 million surveillance cameras (of course, 20 million surveillance cameras are only 1 1.7" in size. Now basically all smart phones on the market are equipped with 1 1.7 "surveillance cameras. ?

Why did you upgrade to 1 1.7 inch? After all, within this limit, more image processing technology is needed to meet the growing requirements of digital photography. Moreover, with the continuous improvement of 5G network and mobile phone wireless charging, and the gradual popularization of 5G Internet, people put forward higher requirements for the camera performance on 5G mobile phones.

With the advent of the 5G era, the laws and regulations on camera performance will be constantly improved. Only by gradually improving the role can we achieve good results. For example, the screen resolution of several hundred million mentioned today will change people's lives to a certain extent, because the 200 million pixel mobile phone must have the thinking of breaking the limit, so that technology can progress.
