Phone camera algorithm is good | Really can do whatever they want?

In the early years, the number of pixels is often the most important factor that determines the camera's ability to take pictures. From 5 million, 8 million to 13 million, 16 million or even 20 million, the high resolving power of high pixel sensors has become a 'photo clarity' As everyone knows, the phone that sink less than half an inch of CMOS, too high the number of pixels also let down the amount of light straight down, causing a lot of noise or violence smear.

In order to solve the mobile phone camera shoot unclear in any case, Google introduced a few years ago for the first mobile phones to improve the quality of the synthesis algorithm, which is now the famous HDR +. Compared to ordinary HDR, Google HDR + not only Can enhance the tolerance of the screen, but also effectively eliminate noise and enhance the ability to restore details.After several years of evolution, more than one synthesis to enhance the quality of the function has become the standard mobile phone mainstream, domestic and foreign manufacturers are all vying for Own new products fit on such a set of algorithms.

Last week, both HTC and Meizu held new press conferences, one releasing U11 EYEs, a mid-range full screen mobile phone and the other an entry-level full screen mobile phone, Charm Blue S6, which at first glance have nothing in common but Introducing the camera at the press conference, both companies have mentioned more than one synthesis algorithm, this feature also invariably become the biggest selling point of two new cameras.

We have today's evaluation of the four mainstream mobile phones on the market, they all carry their own multiple synthesis algorithms, these four phones are HTC U11, Xiaomi Note 3, vivo X20Plus and Huawei Mate 10 Pro. How much use? Phone camera, algorithm 屌 really do whatever it wants? This evaluation will be able to give you the answer.

Evaluation method

Select the typical scene of the day and night, the use of four test cell phone each shot two sets of proofs, the first group forced to close multiple synthesis functions, the second group using multiple synthesis function.After shooting, respectively, compared to each cell phone two sets of proofs Between the imaging quality.This evaluation will not compare the four reference parameters of the camera hardware and ISP, DSP specifications, only for more than one synthesis effect analysis.

HTC U11

First look at this 'single camera photo Wang', although the U11 does not support single camera portrait mode, but HTC's HDR Boost is almost the closest to the Google HDR + multiple synthesis algorithm; available in the market for tolerance, color reproduction and details Performance of these three qualities to make adjustments are only Google, HTC and Huawei.

Daytime scenes, HTC U11 open HDR Boost effectively enhance the brightness of the dark part of the screen, color brightness and saturation, to achieve the effect of HDR; zoom photo can also be seen, a variety of lines on the building in the open HDR Boost's proofs are smoother and smoother, and when not turned on, these details appear with a small amount of smear marks.

In the extreme low light scene, HDR Boost brings the gain effect is even more obvious.In the proofs without HDR Boost, we can see a lot of noise without enlargement of the picture, the entire picture is black; turn on the HDR Boost, the proofs of a substantial increase in brightness, less noise, while the details of the reduction and color reproduction is more in place. The scope and effect of HDR Boost point of view, it can beat it all the industry's only Google's HDR + This feature, HTC U11 alone won a 90-point DxOMark evaluation scores, which is heavily biased in favor of DxO new evaluation rules called rare.

Millet Note 3

Throughout 2017, the best cell phone for millet photography is likely to be the millet Note 3. In MIUI's camera launcher, multiple composite features called 'Night Enhancement', which need to be manually turned on, and each time the camera is restarted After the need to re-open it, it is tossing people.In terms of the scope of action, Milky night enhancements only for color, detail and picture brightness has been enhanced, does not include HDR to enhance latitude function.

It is gratifying that Milky Way Note 3 Night Enhancement not only during the day to eliminate the dark smear and enhance the reduction of detail, but also can effectively correct the white balance of conventional imaging drift problem, we from two proofs in the tone of buildings and pavement You can easily find this difference in white balance.It seems, 'Night Enhancement' is the secret of using millet phone camera, not only at night to open, also have to open during the day; after who say millet phone camera is not good, open the night enhanced , With more than one synthetic film for them to see.

Millet, after all, is not HTC, the face of dim limits, open the night enhanced millet Note 3 also can not beat the details Open the HDR Boost HTC U11, to eliminate the noise depends entirely on smear, it seems a bit embarrassed; but in the color reproduction, millet Note 3 not only lose, but also with more accurate white balance to win back some of the face .As for the group to open the night before and after the enhanced proofs comparison, it is not to mention that you know, all previous millet phone night shot ceiling is This is not open above the proof of the night enhanced proofs, millet for taking pictures of the disadvantaged, the algorithm 屌 although they can not do whatever they want, but enough for them to complete the counter-attack.

vivo X20Plus

Do not underestimate the blue factory, with the price advantage of millet is no longer and music's 'heart and soul', the vivo X20 series with excellent camera and gaming experience has become the price of 3000 yuan cost-effective mobile phone; their Funtouch OS also The only downside is that the UI is too like an apple.X20 and X20Plus standard multiple composite algorithm without a name, as long as the camera in automatic mode imaging, the phone will give you a direct synthesis of good; therefore, If you want to sample sheets with multiple sheets closed, you can only enter manual mode (M position) for shooting.

As with the millet Note 3, Vivo X20Plus multiple synthesis algorithm is only for color, detail and screen brightness, but also to modify the drift of white balance; but compared to millet night enhancements, vivo automatic multi-composite photos will do more Some of the added sharpness and sharpening of the post-processing, the benefits of these treatments is to make the details look more clearly throughout the screen, the disadvantage is that when shooting dense objects will appear more obvious moire.

To give the point of praising is that the blue plant multiple synthesis algorithm is that we have seen the details for the night to restore the most enhance the power to restore the noise reduction details to retain the effect of even playing Google HDR + tie; however, vivo Of the multiple synthesis can not be optimized at night color reproduction, automatic mode (multiple synthesis) of the film in the picture with the M photo actually no difference.It seems that this vivo X20Plus is a comparable JR Smith 's "nerve knife" existence, The advantages and disadvantages of the pros and cons are outstanding, as long as we remember that the blackboard can definitely restore each word on the line (laughs).

Huawei Mate 10 Pro

After reading 'Ham', 'Coarse Grain' and 'Blue Factory', let's take a look at the performance of Chrysanthemum's annual flagship Mate 10 Pro. The trigger mode is the same for the Mate 10 Pro and the Vivo X20Plus, forced in auto mode Open the synthesis of multiple, M file is completely not involved in the Mate 10 series released before 2017, Huawei's new machines (including the glory brand) will be involved in the automatic mode, including the radical multi-HDR synthesis algorithm, but Huawei seems And gave up to follow the footsteps of HDR +, so more than Mate 10 Pro synthesis also works on color, detail and picture brightness.

...... Amount, we carefully compare the two proofs and found that Huawei Mate 10 does not turn on when the ambient light is sufficient synthesis, which may be to ensure faster imaging during the daytime, perhaps because of Huawei International The factory was confident in taking pictures of itself. Anyway, we did not have the option of manually opening multiple compositions and we had to take two identical photos in automatic mode and M respectively, which was awkward.

To tell you the truth, Huawei's Mate 10 Pro's multi-synthesis is the best of the four models for noise reduction in dark scenes, but it is also due to this one-step smear operation, so that the loss of detail reduction Gave Vivo X20Plus; color, Mate 10 Pro outperforms the X20Plus and millet Note 3, almost equal HTC U11. In this glimpse, Huawei's multiple synthesis algorithm still has a certain level, if it can be applied to the daytime shooting Scene, is bound to make Mate 10 Pro the overall imaging quality to the next level.

Spoiler Google HDR + appears, so that mobile phone camera wars from the camera hardware specifications competition directly into a software algorithm and tuning duel, which for the mobile phone manufacturers themselves have higher technical requirements.

In our evaluation, the four mobile phones each array, HTC composite synthesis level is more than the highest reference model; vivo made the best, but defeated in color; millet once again lost in the 'violence Smear 'on the other hand, Huawei is eating melons during the day and night at night, and the four mobile phones each have their own unique features. However, the same is true for multiple mobile phones and their quality of imaging has been improved.

So, mobile phone camera, algorithm 屌 really can do whatever they want it?

'That's right, we just do what we want, giving you the 2000 ISO, and I see how you pull back the details.
