Huawei Mate 10 series after the market, both domestic and foreign authorities or the media, unanimously praised their ability to take pictures .Catch or even surpass the big-looking upwards, Huawei won a key battle, also won the corresponding respect Huawei Mate 10 To get such a good result, in addition to the camera hardware on the 12 million +2000 million pixel dual camera and are F 1.6 large aperture, but also thanks to its self-developed double ISP, and can intelligently identify the camera scene AI Blessing
First, self-study double shot ISP 筚 Road blue strand before harvest
ISP Image Signal Processing, meaning image signal processing. In the mobile phone is mainly used for the front-end image sensor output signal processing unit.In the past, Qualcomm and MediaTek have their own processor R & D supporting ISP to carry their SOC Huawei started using self-developed ISPs from Mate8 and made PrimlSP 2.0 for dual-camera upgrade on Mate9 for image enhancement, color correction, color enhancement, dynamic range compression, gamma correction, As well as super resolution and video anti-shake.
Different from other manufacturers using QUALCOMM or MediaTek ISP once and for all, HUAWEI's imaging department chose the hardest way from the outset. The path to success, the difficult start-ups and constant debugging and experimentation finally enabled the Mate 10 to start with Research dual ISP, and benefited from self-developed ISP can be specifically for their own lens to optimize the Huawei Mate 10 to 'radical' earlier than other dual-F 1.6 aperture equipped with a larger aperture in the camera to get more Into the amount of light to enhance the effect of dark light camera, and combined with the dual ISP, to achieve a variety of advanced games to play and Practice also proved that Huawei had chosen to independently develop ISP this choice is correct, once insisted on the most difficult way, and now , Its dividend brought by mobile photography is just beginning.
Second, the AI scene recognition artificial intelligence final force
AI (Artificial Intelligence) is no longer a new term for 2017, and Internet companies have already begun to hype about this concept.Huawei Mate 10 conference just made its cautious, then Huawei has always been pragmatic in the Mate 10 On the carrying of AI photography is how to achieve it?
▲ Kirin 970
First of all, from the unicorn 970 this artificial intelligence chip talked about, unicorn 970 is the world's first built-in independent NPU (neural network unit) smartphone AI computing platform, the previous cell phone chip generally CPU (CPU), GPU Graphics processor) as the core of the traditional computing architecture, and Kirin 970 alone set up an AI hardware processing unit, or NPU, to reduce the burden on the CPU and GPU architecture, both to improve application efficiency and reduce energy consumption (compared to the traditional computing architecture Approximately 50x energy efficiency and 25x performance advantage) and provides the hardware foundation for Mate 10 AI photography and AI Scene Recognition capabilities.
In recent years, mobile phone photography capabilities have improved a lot, but some users can not shoot good photos, because many people are not willing to use the professional mode does not understand photography, so unicorn 970 NPU helps users in mobile photography scene recognition, You can make the white user also shoot professional good photos.More concrete realization is that when users use the Mate 10 for taking pictures, as long as the viewfinder on the scene, the use of the knowledge of Kirin 970 map function, the scene automatically classified as The default 13 kinds of scenes, including: blue sky, flowers, plants, beaches, sunrise / sunset, stage, food, text, night scenes, snow, cats, dogs, portraits.
When the artificial intelligence to identify and determine the kind of scene, in the lower left corner of the camera interface will appear that kind of scene LOGO, and automatically adjust to the scene suitable for this preset.According to the author's shots as an example: when the viewfinder When aligning the flowers, the AI recognizes that the current photographing scene should match the preset for the flower, and when the viewfinder is aligned with the sky, the AI recognizes that the current photographing scene should match the preset of the sunrise, so as to automatically adjust some preset parameters, Avoid exposure, color cast problems, restore the real scene, so that photos get better results.
In addition to scene recognition, the current AI in the Mate 10 series of pictures is also committed to a large aperture optimization and text resolution enhancement .As the first to do double camera manufacturers, Huawei for the large aperture mode of tuning has been quite familiar, is one of the few Of the manufacturers can adjust the level of a large aperture, the user can adjust the level from 0.95 to 16 large aperture, the default is 4, any advanced camera players can find their own satisfaction with the shallow depth of field effect, to achieve a natural background The
With the help of the AI, the Huawei Mate 10 can undoubtedly carry out a more natural bokeh under a large aperture, achieving what we often call the "knife-creaming effect" On the other hand, AI's approach to learning text edges also helps to improve the resolution of text in photographs, allowing us to get approximate clarity of the scanned image as we make a photograph containing the text.
At present, the boot interface of a mobile phone equipped with a new version of EMUI system has been changed from HUAWEI to a gradually flashed AI + HW + EU. This shows AI has become a force point of HUAWEI's key layout. In addition to AI now supported on Mate 10 hardware, Some basic AI algorithms are also implemented through the GPU, making some AI functions available on the low end.
Third, constant improvement Endless steady start again
At present, relying on the long-term deep plowing in the dual-camera area, Huawei has enough voice in cellphone photography and plenty of rich experience in cellphone photography, for example, entering the mode selection menu on the left side of the camera interface, including black and white cameras, HDR , Panorama, Super NightScape and other Huawei's playful features are integrated here, and the right of the main camera interface into the setup interface, including the generation of professional photos RAW format, set the resolution and so on, in general, playability is high.
Incidentally, Huawei's dual camera and other wide-angle telephoto + telephoto different, using a color + black and white dual camera, which is due to cell phone photography is very convenient, but the basic hardware, with a great difference between the SLR, into the light , sensor area, etc. Therefore, when choosing a dual camera solution, Huawei will give priority to improving the basic photographing capabilities, such as improving resolving power without the aid of the difference algorithm. The sensitivity of black and white can also bring about the final imaging Big upgrade, in the existing mobile phone photography technology, through the color + black and white program to bring a lot of changes through the main camera 2000M pixel hardware upgrade, Mate 10 can do the same twice as Apple's zoom effect, while Blurred background, the view will not be narrowed.At the same time, black and white + color double camera also makes Mate 10 can use purely black and white lens to take quite artistic photos, black and white photos look more purely color photos.
Little black car in black and white mode faded vivid colors, but with the scene to retain more details, the impression is very pure, literary.
Whether it is the user's reputation or reputation of well-known evaluation agencies endorsement, we can say that Huawei's camera is the absolute first tier, but Huawei will continue its efforts to improve the convenience of mobile phones to take pictures - every beat Is a large, professional - to enhance the picture quality and into a film rate.Huaihua engineers said Huawei's goal is the standard SLR, compared to SLR, high magnification zoom, very dark conditions shooting, blur problems, These are from the current mobile phone can not be solved, so regardless of the hardware or algorithm, mobile phones have a lot of room for development. I believe Huawei will be steady, make more breakthroughs in mobile phone photography.
Fourth, proofs Appreciation
In the sunshine, the flowers and red fruits in these two pictures are brightly colored and saturated, the blurring is sufficiently high, and the blurring is relatively accurate. The edges between the flowers and the blurring background as the main body of the image are precisely separated, The background of the regional virtual is also very natural.
These two are real shots of trees under the sky, the author most worried about before taking pictures is the situation after the focus is distorted or dark coke color, but in fact benefited from the f / 1.6 large aperture and AI recognition scene and carried out By default, both photos are true and bright, both in focus and in focus, and the color saturation is high enough.
Both of these pictures are taken on the iron net at the playground. In Figure 1, the internal playground is focused on the iron net. Therefore, the internal vividness and vivid contrast with the external single black, As you can see in Figure 2, the left half and the right half have enough resolution, so I am satisfied.
This group of photos is a blind test of backlighting photos, without manually clicking the screen to focus on the left of the color of the picture to retain good, the blue sky, the green backboard, ground color, top-down very coordinated. Second, when the sun's extreme backlighting scene, without deliberately finger touch case, automatically capture the pictures retain rich detail.
The last set of pictures of the theme colors are dazzling yellow, the left leaves in the picture, the leaves of the yellow and green with the surrounding gray lattice formed a rather artistic contrast, the edge of the leaves and the virtual blur of the border is quite sharp Small yellow car on the right picture, the background of the trees and leaves are yellow, so I almost pinch a sweat when shooting, worried that Mate 10 can not distinguish between them, resulting in a number of double camera phones have appeared in the virtual However, contrary to the author's expectation, the small yellow car's handlebar and seat edge with the external virtual segmentation quite accurate, well reflects the large aperture shallow depth of field effect.
to sum up:
Therefore, the actual shooting, Mate 10 live up to expectations, no matter what kind of scene, before you press the shutter are AI intelligent recognition and switch to the scene suitable for the default, self-study double shot ISP and double f / 1.6 Large aperture Lycra lens addition, whether the face of light or extreme backlight scenes, can maximize the color and detail of the scene to retain the surprise is that the large aperture mode for the main body and coke We have reason to believe that with the continuous efforts of Huawei engineers and continuous learning of artificial intelligence chips, Mate 10's intelligent photographing will definitely be more ' Eyes' color.
