On March 27th, Huawei P20 series phones were released in Paris. It is not unusual for the P20 and P20 Pro's DxOMark scores to reach the summit. However, the P20 Pro DxOMark score exceeds the previous generation championship by 10 points. So what did the P20 series break through?
As a new generation of Huawei’s flagship product, the P20 Pro breaks through traditional restrictions and pioneers a three-camera system that not only opens up new horizons for consumers, but also leads the development trend of global mobile photography once again, completely overturning the inherent impression. This article is based on hardware. Breakthroughs and algorithmic innovations detail two aspects of the P20 revolution.
One, the most advanced photography system
1. Unprecedented 40 million Leica three lenses
Compared with the mobile phone products of the same generation, the most brilliant feature of the Huawei P20 Pro is that it is equipped with an unprecedented three-camera module. In recent years, Huawei has successfully launched a series of Leica dual cameras with in-depth cooperation with imaging giant Leica. The smart phone products with leading photography capabilities have been highly praised by the industry and consumers. This time, Huawei once again handcuffed Leica to configure the VARIO-SUMMILUX Leica three lenses for the new flagship P20 Pro: Exclusive customization with a super-large 1/1.7-inch sensor 40 million-pixel color module, with f/1.8 aperture lens (equivalent focal length of about 27mm), restores fine details and true color information; 20 million pixels ultra-clear black and white module, with (equivalent focal length of about 27mm) f /1.6 aperture lens, bring classic and rich style tone; industry's first 8 million-pixel telephoto module, with (equivalent focal length of about 81mm) f/2.4 aperture lens, as the world's first third lens, to achieve about 3x optical zoom, 5x 3x zoom, more distant, more transparent world (10x digital zoom).
Bottom one-level pressure dead: The largest size CMOS image sensor in mainstream mobile phone lens.
At present, Huawei P20 Pro has the largest size CMOS image sensor in the mainstream mobile phone market, which is 2.25 times that of the Samsung Galaxy S9+ and 2.7 times that of the iPhone X. The larger photosensitive area brings more compact visual effects and There is little background blur effect in the mobile phone field.
As the size of the photosensitive element increases, the size of the unit pixel is also correspondingly enlarged. The single pixel size of the Huawei P20 image sensor is 1.55 μm, which leads the 1.4 μm of the Samsung Galaxy S9+ and the 1.22 μm of the iPhone X. The pixel area increases. This means that the light receiving area increases, the amount of light is relatively high, and the signal-to-noise ratio rises accordingly.
For the P20 Pro, advanced pixel fusion technology can super-sample 40 million pixels of information into 10 million superpixel images. At this time, the size of a unit pixel is equivalent to 2μm, and its sensibility is significantly ahead of other products in the same period. With its large dynamic range, higher sensitivity can be achieved. With a very low illumination, the Huawei P20 Pro can be used with a sensitivity of up to ISO 102400, which is not only unique in the field of mobile phones, even in the field of digital cameras. Only relatively high-end models can be achieved. In the dark environment, the naked eye can not recognize the object environment, still able to shoot a clear picture.
2. High dynamic range performance
In order to realize breakthrough high-tolerance and high-quality performance in backlighting and other occasions, Huawei not only configured large-size photosensitive elements for the P20 series to achieve the improvement of the underlying photographic performance, but also achieved a RAW domain through the development of a new solution. With multi-frame noise reduction, HDR shooting can achieve an unprecedented level of pure texture. Unlike in the past, HDR photographs using the Huawei P20 series will be first processed by the ISP for HDR processing of RAW data, and then written. That is, The HDR shooting mode of the Huawei P20 Pro is actually done directly to the original image before being written into memory. This is really a professional. From the actual effect of backlighting, this process is really better than Other models.
.
With the help of powerful hardware and processing procedures, the newly launched portrait photography mode brings fresh and new results to portrait shooting. Whether in the backlight or dark light environment, users will get amazing photos.
3. The new zoom system brings a more outstanding image quality
In the past, dual-camera phones were already quite popular on the market. In order to improve the pain points of mobile phone users who could not clearly capture distant objects, dual-camera products with 2x optical zoom performance were also becoming more and more visible. The optical zoom performance was positive. Gradually become the user's mobile phone's conventional requirements. This time, the P20 Pro goes up one level, performing a 3x optical zoom and a 5x three camera zoom, greatly improving the telephoto performance standard for mobile phones. Just click 1X on the camera interface. 3X and 5X, you can easily switch between three focal lengths.
When zooming within 3x, the traditional dual cameras are as clear as before: the black and white module captures grayscale information, which in turn produces fine detail and tone; the color module senses color. Both data are generated synchronously, after superposition, After merging, a photographic work with excellent results is retained - this imaging process is much better than the traditional Bayer filter.
When the zoom is more than 3 times, the third camera will start automatically. In order to realize the three sets of modules, Huawei engineers perfectly synchronize the three core actions: auto exposure, automatic white balance calculation and auto focus. The result is undoubtedly very satisfying. The complex triple-camera module is not a breeze when it comes to technically realizing continuous, smooth viewing of the live view frame when the zoom ratio is switched.
After 5x zooming, Huawei P20 Pro restores colors perfectly and accurately presents hair, eyes and other details. Compared with other mobile phone photos, the advantage is remarkable.
Even when using the 10X digital zoom, shooting posters on a long distance wall, smart zoom shooting with the late algorithm compensation, Huawei P20 shooting the edge of the font is clear, leading to a large extent can be clearly seen.
4. The ultimate 'WYSIWYG'
Out-of-focus is a pain point when many people take pictures. Especially when shooting a moving object, it is difficult to successfully focus on the subject. It is a common situation. Slow focusing speed and poor ability to follow focus are all important factors.
In addition to the traditional 4-in-1 AF (laser focus, phase focus, contrast focus, depth of field AF), users of the P20 series have new options: 4D chase focus. As the name suggests, 4D chase means high speed over the entire frame , Accurately tracking the subject, easily solidifying wonderful moment scenes.
The 4-in-1 focusing system used in P20 series phones has a new laser sensor detection range of up to 3 meters.
The 4D prediction tracking function automatically tracks objects and predicts object trajectories during shooting, enabling faster and more accurate focusing. Not only that, but thanks to the nearly zero-delay high-speed shutter, the P20 Series minimizes shutter lag. Realize the limit snapshot, WYSIWYG.
Using this map as an example, the P20 Pro predicts the longest movement of a character's possible trajectory at the next moment by recognizing a high-speed moving object, and takes a near-zero-lag 1/900s high-speed shutter shot to accurately capture details. While pressing the shutter at the same time The other two phones A and B, A finished hair, the hair has fallen, which means there is a shutter delay, and the clothes part is overexposed; and B not only shutter lag, because the focus is not accurate and the shutter speed is slow, the screen appears smear And fuzzy.
5. Self portrait, can be more beautiful
P20 series mobile phones are equipped with 24 million pixel front module, with f/2.0 aperture lens. Advanced BSI CMOS image sensor combined with color temperature sensor, intelligent correction of skin color under different ambient light.
In the backlight self-timer scene, you can see that the picture on the left of P20 shows a more vivid face, the natural color of the character, delicate, with the appropriate landscaping, the overall effect is fascinating. And the right picture does not perform well as a whole Color control and detail modification, lack of beauty.
Second, the AI master who knows you best: Smart photography experience
The vast majority of users lack understanding of the camera's shooting mode and cannot determine which camera mode to choose in the current scene is more appropriate. Therefore, in order to improve the user experience, help consumers take more satisfying pictures and gradually learn various pictures. The model, Master AI came into being.
1. Master AI (Smart Photo Assistant)
Huawei designs a recommendation engine (Suggest Engine) on the algorithm architecture dimension to obtain the information of the viewfinder in real time. According to the scene recognition, the result of face detection, performs recommendation according to predefined rules, reports to the user operation interface, and records the current The user's operating behavior is fed back to the recommendation engine. By continuously learning the user's habits, it gradually achieves the purpose of being able to recommend to the user a tailor-made, satisfying photographing mode.
(1) Scene detection:
From shallow to deep can be divided into three links: image processing, image analysis, image understanding.
Image processing is the technology that analyzes, processes, and processes images to meet visual, psychological, and other requirements. Image analysis is more important than researching the content of images, including but not limited to various technologies that use image processing. It is more inclined to analyze, interpret, and identify image content. Image understanding is semantic understanding of images and belongs to high-level operations. Through understanding the meaning of image content and interpreting original objective scenes, it guides and plans behaviors. This has many similarities to human reasoning patterns.
Scene detection algorithm combines machine learning, deep learning theory and image analysis and understanding to achieve the ability to distinguish between multiple scenes.
(2) Recommended rules:
How to select the most suitable photographing mode among the multiple scenes identified? This uses the recommendation rule. On the spatial dimension, identify multiple targets identified on a single screen and identify the subject; in the time dimension , Can be done to identify the changes in the target range of the viewfinder, to avoid interference factors.
(3) User habits:
The user can decide whether to enable the Master AI technology. If the Master AI is cancelled during this camera operation, the shooting mode is recommended. The Master AI will restart the recommended camera mode the next time the camera is turned on.
In general, the recommendation model is a smarter application of AI technology on P20 series phones. It also realizes the recognition and recommendation of scenes. It is more interesting that AI will even be used in multi-object shooting scenes. Optimize the recommendation rules by learning: For example, if you shoot a portrait next to a flower, the system will prefer the portrait mode to recommend it instead of recommending the floral pattern.
2. AIS (AI Image Stabilization) Intelligent Image Stabilization Technology
Why is the camera blurred?
As we all know, the exposure of a photo is determined by several factors: shutter speed, aperture size, sensitivity (ISO value), etc. Different combinations of these values directly affect the shooting results.
When the sensitivity and aperture values have been set, extending the shutter speed, ie, increasing the exposure time, can capture the effect of water flow or light flow, but when the shutter time is slower than the limit of the body's handheld shooting (for general mobile phones, approximately For 1/30th of a second, the picture becomes blurred due to 'hand shake'.
When the sensitivity is fixed, the smaller the aperture, the larger the depth of field and the richer the information on the screen. Correspondingly, we need a slower shutter speed to ensure the amount of light entering.
Especially in the extremely dark environment, when the mobile phone is fixed in the aperture, according to the automatic metering, it will inevitably increase the sensitivity or prolong the exposure time. The former is limited by the mobile phone device, which is limited by the human body capacity, resulting in the mobile phone being Poor picture quality at night, 'hand shake' is undoubtedly the natural enemy of the night scene.
The P20 series uses the new black technology 'AIS' (Ai Stabilization) in the night view mode to allow the user to carry out continuous exposure for up to 6 seconds in a hand-held manner, and obtain a totally different from what has always been known. High-quality night photographs. This technique mainly uses AI technology analysis to organize the feature points of each scene in the shooting process, identify the shapes and edges of objects, automatically capture all photos generated within 4 seconds exposure time, and filter them with AI algorithm. Correct the image shift and blur caused by hand shake, and finally superimpose photos, and balance the illumination of each element in the screen to get a perfect night scene image. This will undoubtedly fundamentally solve the regret that you can't hold the night scene. Whether it's a light The silence of the wilderness, or the busy night market, can take clear photos of the HUAWEI P20 series.
In the video shooting, P20 series application AIS intelligent anti-shake technology, to achieve six-axis video anti-shake effect, to effectively prevent the video screen shaking during shooting.
3. 3D portrait lighting effect technology
The P20 series adds 3D portrait lighting function, which uses 3D real-time modeling technology to better match the user's facial features and simulate studio-level multiple lighting effects: Butterfly Light, Theater Light, Classic Light, etc. Front and rear camera Both support this function. The user can adjust the light effect in the viewfinder interface and photo editing interface, which enriches the playability of portrait shooting.
4. Smart camera assistance
When recognizing the tilt of the compositional horizontal line, the AI will intelligently remind the user to adjust the angle of the mobile phone. A group scene with multiple faces can be recognized, and it can intelligently remind the user how to compose a picture when shooting a group photo, so that these precious moments Excellent.
5. AI's overall assistance for imaging related functions
The P20 series introduced the Kirin 970 chip and AI technology, which can be subdivided according to the user's actual environment and scene, and then provide users with assistance for shooting scenes. For example: Zoom shot text, AI clarity of the final text image The degree has a significant optimization effect.
Finally quoted DxO's summary of Huawei's P20 series: We are accustomed to the camera of each new smart phone is slightly better than the previous generation, but when we see Huawei P20 Pro's image test results, it seems that Huawei mobile phone one-time advance One or two generations, the performance is very good. The P20 Pro's three-camera setup is the biggest innovation we have seen in the field of mobile imaging. It is a veritable innovator of the game rules.
The new P20 Pro can select the best camera for a specific shooting scene and combine the image data of the three image sensors with a computer algorithm - which means that in almost every respect it can defeat competitive models and board. The champion of the photo and video rankings. Its zoom and bokeh simulation performed exceptionally well in low light, thus directly defeating its competing models. If you are looking for a smartphone that currently has the best camera available, please Do not hesitate again.
