The phone is the camera! Huawei P20 Pro camera hangs Canon EOS M50 SLR camera

Many photographers are curious. Can the Huawei P20 Pro's camera be better than a digital camera? As a very popular mobile phone since its release, it is a situation compared with the camera, I believe it is a point that many people are concerned about. The digital camera uses a large-sized photosensitive element. The zoom function is realized by an optical lens and has a special image processing unit. The Huawei P20 Pro itself has a small photosensitive element, which has an advantage in data processing speed, and the zoom function is With three cameras and powerful AI image processing technology, you can also take better photos. What image processing technology does Huawei P20 Pro use to make good-looking photos that can be taken by photography white, and how much difference is it compared with digital cameras? Let's compare it together.

In the field of camera photography, such as IPU or AI camera algorithms, Google Camera's algorithm has always been in a leading position. Huawei used the core members of the former Nokia Pureview Pure View technology team to jointly develop a new mobile phone camera system. Huawei P20 Pro is equipped with Sony to develop image sensor and Leica certified lens. The IMX600 sensor on the main camera has 1/1.7 inch photosensitive element and 40 million pixels, which is larger than the conventional mobile phone image sensor. , reached the sensor size of the early professional card camera. Pureview technology can be synthesized by CMOS and optical design algorithms, and eight pixels are combined into one pixel of physical level technology. In order to realize this technology, it is necessary to use a large-sized sensor. In order to realize this technology, Huawei and Sony have developed a qualified CMOS sensor in two years.

And how is Huawei's most proud 4-second handheld super night scene technology solved? First, we need to know that shooting a night scene, setting on the camera will use high ISO shooting or long exposure, high ISO shooting has a bad point is that the noise will increase, the picture looks very dirty. However, with low ISO, you can only use long-time exposure, which requires a tripod. In some scenes with too much light, you can only take three photos with different exposures to synthesize a HDR photo.

Huawei P20 Pro uses black and white dual-lens lens to achieve super night scene function, mainly through 40 million pixel color main lens with 20 million pixel black and white CMOS sensor to obtain image information, and then oversampled into 10 million pixel images. Many people don't know what the meaning of black and white CMOS sensors is, which starts with the construction of CMOS sensors. The color CMOS sensor has a layer of Bayer filter to capture the RGB matrix of the color. Removing this layer of Bayer filter can increase the amount of light. The screen will be brighter under the same parameters, and then combined with the main camera and multi-frame noise reduction synthesis technology. Not only can it reduce noise, but it also achieves HDR effects.

What level of high-quality shooting performance can the Huawei P20 Pro advertise? We compare them through the proofs, so that everyone has a bottom. This time I will use the Canon EOS M50 micro single camera to make a sample comparison.

In the case of good light, the Huawei P20 Pro and the Canon EOS M50 micro-camera have very few differences. Both have good image quality and the details can be clearly seen. The Pureview technology of Huawei P20 Pro can be seen. In the case of sufficient light, the picture quality is quite good. The picture that the original camera is out of will be darker, and many operations are left for post-processing. The smartphone will process the picture and it will look a lot better and brighter.

Due to the limitations of the physical conditions of the smartphone itself, it is inherently a weakness in the background blur. To achieve the blur effect, the outline of the object must be extracted first by the AI ​​algorithm, and then the background is blurred. Through the synthesis process, a blurred photo is generated. The camera's own CMOS sensor is relatively large, and the physics blur will be much more realistic than the simulation. The bokeh effect of Huawei P20 Pro is more natural than the background blur effect of mainstream mobile phones. This is indeed the credit of AI algorithm.

In terms of night scenes, the Canon EOS M50 also has its own handheld night view function, which is used to take three photos for noise reduction synthesis. Huawei P20 Pro also uses multiple noise reduction, but it will take more photos and noise reduction processing. On the screen, the Huawei P20 Pro will be brighter than the Canon EOS M50, with its own HDR feel, but in terms of details, The Canon EOS M50 is much better, and the Huawei P20 Pro has a stronger feel. If it is a simple circle of friends, it is undoubtedly Huawei P20 Pro can also cope with, but also less trouble later, but to wash photos and the like, the camera will have higher image quality and resolution output performance.

In recent years, the competition between mobile phones and cameras has become more and more fierce. This article makes a simple comparison between the two newly produced machines. It can be seen that in the case of daytime, the difference between mobile phones and cameras is relatively small, and it can be said that each has its own characteristics. The original picture is straight out of the color of jpg, the phone will be obviously good, and the camera will have more post-color space. In terms of night scenes, although the brightness of the Huawei P20 Pro is much better than that of the Canon EOS M50, the Canon EOS M50 will have a greater advantage in terms of magnification and latitude.

The so-called big-level one-time crushed people, this point on the mobile phone for portability, the sensor size can be said to be unable to catch up with the camera, so the smart phone is more to do more on the algorithm, this curve will save the country's method will be suitable I simply took a photo with my mobile phone, didn't understand photography, and didn't want to do a lot of post-actions. And digital cameras are suitable for photographers who have high-quality photos, both in terms of blurring effects and image quality details, which are difficult to achieve with mobile phones. Huawei P20 Pro uses the updated mobile phone shooting technology to win the highest score of the DxO mobile phone list. From the proofs, it really makes the camera ashamed, and it can be used for shooting in many occasions. I also believe that there will be a higher breakthrough in mobile photography in the future.
