Why is the shooting experience of mid-range mobile phones getting better and better?

The wind is not halved, and the rain is more fun. Hello, everyone. The following is a small series of deep space, focusing on eating melons with everyone. The editor has been editing for a long time and brought this article to everyone. There is no suspense, let's meet.

Taking photos has become one of the most important selling points of smart phones. Now the design of 4-5 rear cameras densely arranged on the back of the mobile phone is no longer exclusive to flagship machine. Many configuration combinations that once belonged to high-priced smartphones began to appear more and more on products in the price range of 2000-3000 yuan.

After careful observation, it is also found that both Redmi K30 5G and OPPO Reno3 Pro, which went on sale at the end of last year, and realme X50, vivo Z6 and ZTE Axon 1 1 which appeared this year, all adopted the design of rear four cameras.

When the rear four cameras have gradually become a development trend, many manufacturers will choose to add a lens with 2000, 5000 or 80 million pixels on the basis of wide-angle, telephoto and ultra-wide-angle lenses, which is responsible for depth of field and macro processing.

However, under the existing technical conditions, this kind of shooting scene with small lens, main camera and ultra-wide cooperation can be completed.

What really changes the mid-range mobile phone camera experience is actually the 1-2 core lens, such as the main camera and the ultra-wide, especially those mentioned above. Basically, 48-megapixel and 64-megapixel sensors are used as the main cameras, which are responsible for 80% of your mobile phone photos.

A year and a half ago, you obviously won. Such a high standard camera sensor is invisible on the mid-range machine.

On the one hand, the cost of high-standard cameras is indeed decreasing, just like six-core eight nuclear processors will be distributed to thousand-yuan cameras from flagship machine, which is still rare today.

On the other hand, more cameras appear on mid-range mobile phones, which also means that the processor on the mobile phone has strong enough performance.

After all, mobile phone photography not only records images, but also involves additional processing such as image synthesis and color optimization, which requires a lot of computing power of the chip.

Last year's S Xiaomi CC9 Pro is a typical example. At that time, not only the Quad-Bayer main camera with 1 100 million pixels was equipped, but also two sets of telephoto lenses with different focal lengths, with five rear lenses. At that time, some people thought that the Snapdragon 730G chip on this machine might not be able to handle such complicated work.

But in fact, according to the data of official website, Qualcomm, Snapdragon 730G chip can support a single photo shooting with a maximum of 1 0.92 billion pixels, which is enough to realize the10 billion pixels of Xiaomi CC9 Pro. Dxomark finally gave the machine a high evaluation of 1.30 points.

This year, Qualcomm also launched the Snapdragon 765G chip specifically for the 5G era, which also supports photo shooting with a pixel of up to 65.438+0.92 billion, and multi-camera combination with telephoto, wide-angle and ultra-wide-angle lenses.

Therefore, this year, a batch of mobile phones equipped with Snapdragon 765G can naturally use higher standard cameras to narrow the imaging gap with flagship machine.

The influence of Snapdragon 765G on the mobile phone camera experience is not only the number of pixels and cameras, but also many new camera functions we saw at the press conference are inseparable from its technical support.

One of the most important points is the smooth switching of multiple cameras. In the early years, there was a significant problem with multi-camera mobile phones, that is, when different lenses switched to take pictures, the pictures from different perspectives would have a sense of fragmentation.

The current practice of Qualcomm S is to use AI Engine, the fifth generation artificial intelligence engine built in Snapdragon 765G, to improve the fluency of multi-camera switching with AI. At the same time, it can also make high-pixel photos generate faster and bring instant experience to users.

Moreover, in theory, it is not impossible for AI to automatically adjust the chromatic aberration under different lenses, use neural network learning algorithm to reduce the noise of images, and even change the results of photometry and white balance to improve night scene imaging.

When we evaluated OPPO Reno3 Pro before, we also found that the performance of Reno3 Pro is obviously better than that of RENO2with the same configuration in dark environment. Whether it is the highlight suppression of light or the retention of dark details, it is visible to the naked eye. It can be seen that the upgrade of the processing chip will really change the camera experience of the mobile phone.

Another technology hidden in Snapdragon 765G is computer vision ISP, which actually enables machines to know how to extract, classify and recognize image features like humans.

However, in the past, the older generation of chips relied on software to realize computer vision algorithms, which required additional CPU resources. However, since Snapdragon's 855 era, Qualcomm has turned to ISP hardware to accomplish these tasks.

Specific to daily use, this Snapdragon 765G supports multi-person facial recognition, which can track people's state and movements to determine the best shooting position; You can also switch the background through AI without affecting the subject, and automatically change the ugly background in the photo into another one, which also involves the maturity of the image segmentation algorithm.

Of course, these tasks are all realized by the built-in Spectra 355 ISP of Snapdragon 765G, and the independent ISP hardware also brings higher processing efficiency.

In terms of video recording, this year's Snapdragon 765G also inherited some features of Snapdragon's 8 series flagship chips, and supporting 4K-HDR video shooting is one of them. Compared with SDR, HDR can shoot more than 1 100 million color images, showing better color saturation and more realistic light and shadow details.

This photo is only a part of Qualcomm, which is an improvement of Snapdragon 765G chip. Further exploring its highlight function, we can also find things like 7nm process technology, 8-core architecture composed of two cores and six small cores, integrated 5G baseband, high refresh rate screen supporting 120Hz, and even some Snapdragon elite game experiences consistent with Snapdragon 8 Series. It can be said that the comprehensive strength of a God U is very strong.

According to Qualcomm, the G in Snapdragon 765G stands for game, which means that many of its functions are provided for gamers.

The mid-range mobile phone using Snapdragon 765G can use a better camera because of its strong performance guarantee, and get the photo effect without losing flagship machine. The appearance of Xiaomi CC9 Pro shows us that the combination of mid-range processor and top lens is not impossible.

If manufacturers can tap the potential of mid-range chips, they can still make first-class camera phones.

Perhaps this year, there will be more and more mid-range mobile phones equipped with flagship cameras. For those users who like to take photos, it is also a good thing to buy more suitable products at reasonable prices.
