image：The simple but not simple three-camera module can still play with the blessing of the new algorithm
Although it is a "small cup"，But as a P series，Imaging is also the highlight of Huawei P50。
Compared with its big brother, Huawei P50 has changed from four cameras to three cameras，The extreme zoom range is also smaller，Although the imaging ability is not so top-notch, it is still quite capable.，because，After all, the algorithm is the soul of the P50 series。
This time, the Huawei P50 series can be described as a two-pronged algorithm.，old friends”XD Fusion”Upgrade to Pro version，Can better optimize the brightness of the film、color，even content-specific enhancement details、Layering。
There is also a new friend "XD Optics" computational optics，Targeted algorithm tuning for the optical system of mobile phones，After confirming the distortion caused by the light passing through each lens，Then carry out algorithmic correction on the image in a targeted manner，Thereby greatly avoiding the optical system of the mobile phone from dragging down the hind legs of the entire image module。
The former is about taking pictures”Post-processing”，The latter is related to the acquisition of optical data in the early stage。 when taking pictures，First use XD Optics to calculate optically to remove the interference caused by optical defects，Restore and preserve more valid metadata，Then through the new XD Fusion Pro graphics engine，Further optimize the performance of the film。
Take a look at the process of taking a photo，Huawei P50 will not present the final sample immediately after the shooting is completed，Instead, there will be a process。 This process is how the mobile phone optimizes the performance of photos through algorithms.。
It's overexposed everywhere、Noisy night scene，after processing，Greatly improved dynamic range and clarity，Even the clarity has improved a lot。
Although due to the limited rear camera specifications of the P50，The combination of black and white main camera and high-pixel telephoto is missing，The resolution of the final film and Huawei P50 Pro is much worse。
but you can't deny，The overall look and feel of this night scene photo under 10x telephoto is still excellent。 This is what computational photography is all about，Through in-depth optimization can turn decay into magic。
With the support of the new algorithm，The imaging style of Huawei P50 has also undergone a lot of changes。 If we say that the past Huawei P series left a bright impression on everyone in terms of imaging style，Then this time Huawei P50 returns to the original intention，what you see is what you get，Restoring the color of real images will become a new trend。
What is WYSIWYG，In the final analysis, it is actually to restore the true color，one step deeper，This actually depends on the tuning of many parameters such as white balance and color temperature.。
Huawei P50 is equipped with a new generation of environmental spectrum information collection sensor，Can wirelessly approach the spectrum of nature，Realize the true reproduction of color。 In these comparisons，Huawei P50 is exactly that，The color is closest to the real visual perception。
restore color，For the Huawei P50 series，It is not an absolute restoration of the true color of the object。 like a blank sheet of paper，It will never appear absolutely white in the sunset，Because the color of the ambient light also affects the object”actual color that looks like”have an impact，Considering the actual lighting, the color determined is the most realistic。
Huawei P50 is not the color reproduction of absolute white balance，Instead, it truly restores the perception of the naked eye，This is the core of what it sees is what you get。
on a cloudy day，Many mobile phones generally suffer from insufficient light，Photos taken will have a faded texture，However, Huawei P50 can use algorithms to avoid this problem.。 Although low light photography，Still capable of the most vivid colors，Attract the user's attention。
The three shots of Huawei P50 also have a very high consistency，main camera、The color performance of telephoto and wide-angle is basically the same，Can truly restore the real scene of each focal length scene，5The mist under double telephoto is also accurately recorded，true restoration。
The night view of Huawei P50 is also very worth mentioning，All three cameras can use night scene mode to shoot，And the film is not bad。 Not only can suppress the light overexposure at the same time，keep the lights on、Atmosphere created by glare，More importantly, it can restore the true color of the light，It can be said that it is all thanks to the new algorithm.。
like other brands of phones，Either the light is suppressed too hard，Lose the atmosphere of the light;or increase the brightness too much，distort the color，They all need to continue to work hard on the algorithm。
The telephoto on the Huawei P50 is a periscope telephoto equivalent to 5 times the focal length，Has 12 million pixels，CMOS size and number of pixels are much smaller than the telephoto of Huawei P50 Prp，There is no auxiliary black and white main camera，Therefore, the image quality is also slightly inferior。
5Under the condition that the periscope lens is fully invoked with a focal length of 2 times，If the weather is bad and there is not enough light，The details of the imaging will be greatly reduced。
Another problem is the call of the main camera and telephoto，The Huawei P50 is directly equipped with a 5x periscope telephoto，without any transition shots in between，Therefore, there will be a serious loss of image quality between 1-5 times。
Example shown above，4.7The finished film has already shown a strong smear feeling，And the 5x full use of the periscope telephoto lens is much clearer。
For the limited space of Huawei P50，It is also reasonable that more and stronger rear cameras cannot be inserted，However, with the help of multi-camera fusion algorithm，In fact, it can also improve the center image quality of the middle focal length to make up for it.，Hope to see improvements in this area in future system updates。
limited by size，Huawei P50's rear three-camera looks ordinary in terms of hardware，There is no super big bottom super high graphics element，There is no black and white multi-camera assistance。 But because of the computational optics、The latest algorithms such as XD Fusion Pro and True Tone engine，So it still has an excellent filming rate in various scenarios，And the best look and feel is guaranteed when you shoot it。
Other mobile phones may have very powerful rear camera hardware，But it is difficult to achieve one-click filming like Huawei P50。 Huawei saves the user from adjusting the color in the later stage、exposure、Even post-processing steps such as brute-force stacking to optimize images，After shooting, it is a perfect photo that can be directly shared，Such a powerful full-process image processing capability is the charm of Huawei P series images.。
