2017 Mobile Phone Camera Technology Forecast | Written by MWC 2017

On this Sunday, the annual Barcelona Mobile World Congress will be opened. As a transition from a digital photography practitioner to an enthusiast, I am also one of the events of the year. In recent years, it has been very keen on mobile photography. There are also a large number of camera phones used by various brands. This year, they also want to learn a big V to analyze an inconsequential future trend and talk about mobile photography.

Since we must look forward to the future, we must first look back at the past.

2016 was an ordinary year for many people, but it was an unusual year in the mobile phone industry: an Android machine that was almost perfect in many people's hearts became the shortest-lived flagship; mobile payment basically became a young person. The necessary skills for survival; fingerprint identification has become a standard for many brands of high-end mobile phones or even entry-level mobile phones; Leica, Hasselblad entered the field of mobile phone photography; Apple did not give any surprises, only a crappy dual camera; consumption Modular mobile phones were listed, but the basic calculations failed; thin and light phones began to abandon the 3.5mm headphone jack; 2016 is still the first year of the VR industry and the domestic live broadcast industry, and it is really an extremely busy year.

In terms of smart phones, it can be seen that, in addition to routine upgrades of CPU and memory, major mobile phone brands still differentiate themselves in photographs, HiFi, and other areas such as hyperboloids, borderless, and sub-screens, in an attempt to enhance their own development. Product competitiveness. So what are the areas of mobile imaging that I personally care about? In fact, there are also many hot spots, as the flagship mobile phone must compete for the camera, as if it also came to a watershed, we are not satisfied with a clearer picture quality, faster focus, more accurate exposure, better noise reduction Algorithms, and each of them began to engage in new "things" go, 2016 is a beginning, we saw something new:

It's been so exciting to take a picture of the phone for a long time.

Witnessed the phone camera from scratch, evolved from 100,000, 300,000 pixels to 20 million pixels, auto focus from scratch, from the rough approximation of the LOMO camera to the current level of low-end digital cameras, mobile phones The development of taking photos on this road seems to me like an unavoidable trend. Everything is as good as the development of the original digital camera. Therefore, it doesn't feel very exciting.

However, by 2016 (actually from the second half of 2015), it is quite different. We have seen several “unique secrets” for taking photos of mobile phones first. The most prominent ones should be the following three: Apple, Samsung, Huawei.

The apple does not need to say much, the dual camera portrait mode on the iPhone 7 Plus, through the second telephoto lens with software recognition, maps, optimization, in order to achieve a photo with bokeh effect. Although this type of feature has a lot of limitations and the type of photos that can be taken is limited to half-length portraits, it requires a lot of light and plenty of light. But after all, the reputation is high, and the market share is high, so many "meat people" know the concept of "dual camera", but also make many people mistakenly believe that any camera with dual cameras should be very good. It can be said that the dual camera function of the iPhone 7 Plus is the most disappointing new feature for mobile phones in 2016. Although the dual camera is not Apple's first product, the front htc, LG, and some domestic brands have launched dual-camera mobile phones, but the appeal is less than Apple, so did not trigger the industry's dual-camera trend .

With powerful R&D capabilities and an almost self-sufficient industrial eco-chain of key components, Samsung’s Galaxy S7 edge comes with a spike-sized Dual Pixel focusing black technology, and a 12-megapixel super single pixel size brings a night-time shooting scene. The extremely high picture quality, plus F1.7 large aperture, hyperboloid screen and excellent body design, made him no suspense to become the strongest camera phone in 2016 (the later released Galaxy Note 7 had almost no photographing Big improvement). After my iPhone 6s battery problems, S7 edge is my daily machine.

Looking at Huawei again, Huawei chose to take an unusual but very immediate road - hold the thigh, and the P9 series with Leica's color palette for photographs sold 10 million directly, and this result was released in April 2016 to the end of the year. Realized in about half a year. Of course not only Leica, Huawei's mobile phone in the imaging quality has also risen a large part, while taking out their own dual-lens program, and earlier than the apple. Unlike Apple, Huawei uses a combination of color and black-and-white sensors to capture details and colors respectively, achieving better details and night scene effects. At the same time, Huawei also has an algorithm for simulating background blur, although there is no apple algorithm. The precision (actually everyone is half in touch), but the application is very wide, in some occasions the effect is also very good, so the Huawei P9 is the most exciting mobile phone in 2016 (no one, now still carry when the camera is used ). I have to say a few words here, that is, Huawei's Mate 9 series, in addition to P9's critically acclaimed elements, has raised the pixels of the second camera, and implemented an "optical zoom" function in a disguised way by cutting pixels. , let the "Leica color + dual lens" this killer to a higher level. It can be said that the rise of Huawei's mobile phone camera is the biggest surprise for me in 2016.

What are the reasons for everyone to develop their own camera system, rather than just pursuing higher targets? My analysis has the following points:

1. The development of a mobile phone camera has encountered a bottleneck, and seeks directions. Nowadays, the photographic effect of the mobile phone is good enough to meet the daily needs of most users. In addition to the fact that Samsung can continue to increase its photo-taking by violence, how to further enhance the competitiveness of its own mobile phone photography has become a problem for many brands in the product planning of mobile phone photography. Combined with the analysis of the current market demand and the solutions promoted by suppliers, each of us has chosen different development directions.

On small photosensitive elements, high pixel and single pixel area have always been a contradiction. To put it plainly, the balance of photo size and image quality is where mobile phone manufacturers have been tangling. It seems that there is no new black technology. Before, 12 to 16 million pixels is a balance;

2. Due to the endless pursuit of thin and light mobile phones, the development space for mobile phone camera components is getting smaller and smaller, and it is really difficult to play with new tricks, only to test the water in multiple shots and new technologies.

3. The mobile camera component suppliers also encountered bottlenecks in the development of hard indicators. In order to seize opportunities, each launched its own solution and persuaded the brand to use it on its own products.

2017 flagship mobile phone camera function forecast

Less than one week later, each 2017 new product will be released in Barcelona. From the current point of view of various leaked information, it can be summarized as one sentence: 2017 is still a flourishing year for mobile phone photography. Why do you say that?

First of all, from the two most leaked mobile phones, one of them, the Samsung Galaxy S8 (or even the Galaxy S8 Plus), is still using a single camera configuration from a seemingly more realistic leaked photo. It is not impossible to think about it. After all, Samsung’s current technological advantage in taking pictures on mobile phones is very obvious, and Dual Pixel is its own unique technology and will not be easily taken away. On the S8, you only need to improve on past deficiencies (this point can be seen from Note 7), such as exposure accuracy, color style, etc., the overall performance, I think Samsung can at least lead One year. The improved ID design, the proportion of large screen is the focus of this S8.

Let's look at another leaked LG G6. The leaked content is very consistent and highly reliable. It can be seen that the G6 has also continued the dual-lens strategy of the past G5, plus LG has not always loved to follow the trend of the mainstream, I believe this is still the ultra-wide-angle strategy contrary to the iPhone.

Let's talk about the legendary iPhone 8, everyone is very much looking forward to him, one reason is that the iPhone 6's industrial design used three consecutive generations, and claimed that this year is the iPhone 10th anniversary, some speculated that Apple will have a big move, so follow the previous Regular iPhone 8 should be released in the second half of this year, but now there are already many rumors and fan concept designs. According to my judgment, Apple used the dual camera technology for the first time on the iPhone 7, and Apple's implementation of the new technology is long-term and in-depth. It will not be easy to go on, and it will not be easily removed, so there is reason to believe that the iPhone 8 Still using the dual camera configuration, perhaps more on the sensor, it is estimated that there will be a larger pixel size, and a larger aperture, improved "Portrait mode" algorithm, so that the effect is more realistic and even expand it The scope of application.

Let's look at Huawei again. Rumor has it that P10 will be released in Barcelona. The related wind has also gotten some, but since Mate 9 has upgraded Huawei's dual camera to a 20 megapixel level, this configuration will be decentralized to P10 Plus, and then remove the anti-shake. Put it on top of P10, so I believe we will still not see anything new.


In addition, it is said that the 5X technology announced by OPPO in Barcelona soon to be announced is a periscope-based optical zoom, and watching the official notice video can also see some clues, mainly talking about the technology to change the light path, it is also clearly periscope The meaning of optical zoom, but look at the structure of the optical path in the video, I feel a few corners turn, is it through a number of 90-degree corner to achieve a large zoom in a small area mean? (Perhaps thinking more, they just want to spell a 5 word...) Now, wait, hopefully this is a new technology that can be applied to the final sale of the product, not just a technical prototype. (Remember last year's OPPO's ultra-fast flash charging technology ~)

In addition, it is said that Sony also has a large number of new products to be released on MWC 2017. SONY, as a supplier of photosensitive chips, does not know whether it will first introduce new CMOS products on its own machine. It is said that IMX400 will be upgraded. New innovation? ! The information that has been revealed so far is not a lot. I only heard that there will be follow-up models for the Z5 Premium, which must also be a flagship model.

Finally, there is HMD's NOKIA brand, in addition to continuing to attract people with feelings, it is said that there will be 40 million pixels PureView models launched, this is not easy to say, we wait and see.

In general, according to my own judgment, at this MWC 2017 conference, the key word should be “Mobile ID Design Change”. Both Samsung and LG will use their own high-screen ratios during the competition. It indicates the future direction of an industrial design for smart phones. In the field of mobile phone photography in 2017, we will rarely see any innovative imaging technology or innovation in the application field. However, the pace of technological development has been different. The strength of domestic manufacturers has basically caught up with the international big brands. It is possible that domestic brands will put Samsung and Apple under the top two.
