For example, Huawei Mate 10 series just released in China some time ago is the latest successor to the well-known 'Leica Dual Camera.' If you are curious about the Mate 10's photo 'secret,' you may wish to patiently read the author's This detailed explanation.
Lens: The new series, the industry's largest aperture
Any photographer who has a little common sense knows that the benefits of large apertures for imaging are much more than 'avatar'. First, a larger aperture means more light per unit of time, so Even with a higher shutter speed, but still be able to get bright enough photos.And higher available shutter speed directly means less jitter and better capture ... ... For mobile phone photography this 'easy to beat' The model is even more icing on the cake.
As a result, the Mate 10 series is equipped with the LEICA certified 'SUMMILUX' lens is particularly exciting: as Leica's flagship large aperture lens series, the realization of the smart phone Mate 10 first echelon double f / 1.6 aperture parameter, exceeding the previous P10 Plus lens level.
To be honest, at this stage of mobile phone lens, excellent quality is too little - and the lens is precisely the first and most crucial step in the shooting process. It is the quality of the lens determines the image imaging features, such as everyone In fact, the favorite 'Devil' Vignette is actually determined by the optical characteristics of the lens. From this point of view, the Mate 10 has an excellent lens and a good imaging system is the first step.
ISP: dual-core design, higher performance
After the lens captures the light, the optical signal is converted into an electrical signal by CMOS (that is, our commonly known image sensor), and then the ISP (image signal processing unit) performs various processes such as image noise reduction and synthesis, and finally Generate the photos we see.
Mate 10 using the CMOS configuration and the previous generations of little difference, 12 million color +2000 million black and white dual-CMOS is the current double-camera category in the leader, there is no replacement for a short period of time.But in Mate 10 built Kirin 970 SoC internal, responsible for taking pictures of the image processing ISP has been upgraded.
The unicorn 970 integrates dual core ISP units based on the previous generation's improvements and continues to support the iconic 'four-mix focus' (contrast, phase, depth, laser) of Huawei's dual-camera phones. It automatically selects under different light and distance conditions The most suitable focus.And the new ISP unit data throughput increased by 25%, the corresponding time reduced by 15%, which means that it can be in a shorter period of focus, noise reduction and other data processing is completed.
Do not underestimate this 25% increase in throughput, as the current cell phone camera algorithm using a large number of multi-frame synthesis technology, in most cases the user presses the camera button on the APP, the actual number of photos taken within the phone more than one, Need to be calculated by the ISP synthesis to produce the final image, so the higher ISP performance, the synthesis of the shorter the time, is reflected in the use of the experience is the photo in the album can immediately see a clear processed photos - This can be Not easy.
Of course, thanks to the 10nm semiconductor process used by Kirin 970, the new ISP does not increase its power consumption while maintaining its performance, but at a reasonable level, the new ISP can use the longer , Shoot more.
AI photo: 'your photographer'
Here, maybe some friends to ask, that the ISP have processed images generated, the process of taking pictures would not end it? Say good AI camera, AI has played a role?
In fact, this is the clever place for Huawei Mate 10. Its integrated AI algorithm is not only used for processing images, but more for assisting the user, helping or even adjusting the camera instead of the user Many parameters of the process, like standing behind the 'photographer', so that the average user can shoot a more beautiful 'masterpiece' come.
In order to do this, Mate 10 built-in AI chip has been learned in the factory as many as 100 million photos, extracted from it, summarizing a large number of different shooting scenes, the characteristics of the subject information.
In the process of taking pictures, the AI can judge the environment of the current camera picture, the type of object (portrait, pet, food ...) and so on in a very short period of time, and automatically adjust the white balance, shutter time, ISO, exposure compensation , The filter choice to wait for a variety of past needs of users to set their own parameters based on their experience, as a result, even the 'white' users can also take a reasonable set of images appearing strong photos naturally will be on the phone Photography is more interesting.
Of course, some of the old birds will not accept: I know photography very well, I usually use my cell phone to take pictures and also open the professional mode of my school tuning parameters, that AI is not useless to me? Not exist! Because AI can recognize, auto-tuning parameters far more than the user can touch more.For example, the text automatically enhance the camera, the internal multi-frame synthesis, edge noise reduction, sharpening and other functions, under normal circumstances, mobile phone users can not be adjusted However, AI has a higher level of 'authority' and can adjust more picture parameters and imaging functions, so that even a professional user can still benefit from AI's assistance.
Summary: AI, so that more people fall in love with pictures
Above, is the author of Huawei Mate 10 'AI camera' function analysis, after reading, is not this pair of camera flagship phone feel some eager to do? In my opinion, to be able to take pictures is not A particularly difficult thing, at home and abroad known as 'camera flagship' or take a photo as a selling point of the phone really a lot, but to allow users who can not take pictures can be good, this is really reflect Horizontal - in my mobile phone, can really do this is extremely rare.
Of course, the Huawei Mate 10 is not a cell phone that simply takes pictures as a selling point. It is also a rare flagship large-screen business machine in China and a rare 'AI system' phone. However, taking this picture alone, The users who come into contact with Mate 10 are not only fond of this mobile phone, but have gradually gained confidence and interest in Photography. I think it is remarkable.
