Meilan U20 is the most low-key and offline machine in Meizu's history. Some users may be curious. This parameter is quite mysterious. Even if there is a mobile phone on the official website page, what will happen to its photos?
In order to better measure the photographic performance of the Meizu U20, we use the slightly higher Meizu E (Sony IMX258) and Meizu Note3 (model unknown) as a comparison. The three Meizu 1000 yuan computers are all 13 million pixel sensors that support phase focusing. The large wide-angle lens of f2.2 is very similar in setting.
The Samsung Galaxy Note5, as the standard sample of the top flagship, shows a huge gap between the flagship and the thousand yuan level photos. Its imaging characteristics are excellent discrimination, obvious sharpening marks, and a certain tendency of yellow and warm white balance (especially under warm lights such as coffee shops). The noise control is general, and the dark details of extremely weak light and super light difference scenes will have special white fine noise. At present, the comprehensive strength is also the top level.
Investigation items and scales
The core of mobile phone photographing is the photographing experience and imaging effect. The main factors that affect the experience are:
speed And also includes focusing speed, shutter response and imaging speed;
Film rate , the probability of destroying the film by shaking hands;
Degree of automation , whether it can identify the scene with large light difference and weak light, and automatically trigger HDR and night view mode;
Ease of use , whether the viewfinder box has problems such as delay/shadow dragging/frame dropping/noise full screen, but the priority is not as high as the first three.
The imaging effects mainly include:
White balance and photometry In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Discriminative power Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
Tolerance , that is, the ability to show details in the light and dark at the same time. For mobile phones, this is basically equivalent to whether the HDR effect is natural and harmonious, whether there are ghosts, white balance deviation, and poor discrimination after synthesis;
The remaining assessment contents include noise control, color saturation (the closer to the naked eye, the better, but Samsung and Huawei will be able to raise it recently to please users), lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow deformation control, etc.), and many other contents.
Although everyone's requirements for photographic experience are almost the same, for different users, the proportion of different imaging projects is completely different: for example, the number of Maoists who like to enlarge photos and scan will definitely put discrimination first, and the proportion is very high; The party in the circle of friends attaches great importance to tolerance, white balance, saturation and other items, but the requirement of discrimination is not high. Therefore, the comparison will be divided according to different items, and it will be better for everyone to focus on understanding what they care about.
Photo experience
Camera interface and intelligence: the camera interface of the three Meizu 1000 yuan machines is the same, which is of the type with minimal functions and good usability. There is an automatic night view, but HDR needs to be turned on manually, so the degree of intelligence is average
Shutter response, imaging speed, HDR and night scene processing speed: after Meilan Note3 presses the shutter, the shooting stops for a few tenths of a second. The other two machines have no such problem. The imaging speed of the Meilan U20 HDR、 The night scene mode is very close to that of Magic Blue E, and the last two take nearly 2 seconds, which is faster than that of Magic Blue Note3, but there is still some distance from the flagship.
Focusing success rate and film forming rate: the performance of Meilan Note3 and Meilan U are commendable. Although there are obvious bellows under extremely weak light, almost all of them can successfully focus. However, the most expensive MBE automatic focusing will have a certain out of focus probability. Manual light measurement is very sensitive and easy to overexpose.

Scenario 3
Meizu is the only big manufacturer that can compare with Xiaomi's HDR in the market, and these two domestic brands have not yet adjusted their own HDR algorithm. Compared with Meilan E, Meilan Note3 and other predecessors, the HDR algorithm effect of Meilan U20 is still not improved.
Meizu HDR is characterized by obvious enhancement of dark details, and excessive brightness on some occasions. The adjustment of color temperature is not heavy, but the saturation of green will be seriously affected, and the sense of oil painting is very, very heavy. The availability of its HDR is even lower than that of Xiaomi's, which is not recommended at all.
Lens quality&wide angle
Although they are all 13 million yuan, the sample of Meilan U20 is slightly smaller. However, in terms of wide angle, Meilan E is smaller than Meilan Note3 and Meilan U20. In exif, the former is 3.46mm focal length, and the latter two are 3.5mm focal length.
Proportional amplification
Meizu is the one of all mobile phone manufacturers that loves wide-angle camera most. When other manufacturers are using the equivalent focal length of 27-29mm, Meizu uses a wide-angle lens of about 26mm, and its mobile phones in the past two years are almost in this wide-angle range.
The wide-angle lens will have a quite obvious effect when shooting at a close distance. The range of the scene shot at a distance of 2m is several circles larger than that of Note5 with an equivalent focal length of 28mm, and it will be slightly smaller at a distance of more than 10m. In addition to the difference between 16 million pixels and 13 million pixels, the scene taken at a distance of 10 m is magnified proportionally, and the size of the scene is very obvious, which also determines that the discrimination of Meilan and even Meizu series is not very good.
Of course, wide angle is not without its advantages. It can make it easier for users to take photos. One photo can capture more things, which is the choice of the manufacturer. Just under the balance of wide-angle and discrimination, the author is more optimistic about the approach of tendency to discrimination. After all, in many cases, if the camera can't put down enough, you can still step back a little, but the loss caused by insufficient discrimination is beyond the control of users.

The lowest price Meilan Note3 is also significantly behind other mobile phones in terms of its imaging level. The white balance is far from the mark, and there will be yellow green problems in different ranges from time to time. The quality of the lens is poor. Even in the daytime, it seems to be covered with a layer of gray. The edges of the scenery are blurred and the discrimination is terrible. If the light is weak, the ISO and smear will go crazy. The noise control is good, but there is not much detail left. The overall leveling can only record the contour. Even if it is used to scan the two-dimensional code, the light should be better.
Meilan E uses a wider and smaller lens, and is the first machine outside Meizu's flagship series to use Sony IMX sensors. Its imaging performance is also the best of the three Meilans. The perceptual summary is that three positions are better than the Charming Blue Note3 and two positions are better than the Charming Blue U20. The white balance is blue-green, but the range is acceptable. The daytime discrimination power is the normal 13 million sensor level, and the weak light noise is also the best part of Magic Blue.
The Meilan U20 is a very eclectic product, sandwiched between Meilan E and Meilan Note3, but closer to Meilan Note3, the actual imaging is still disappointing, and it is only slightly better than Meilan Note3 on the whole. The extreme quality of the lens is average. Even in the daytime, the extreme details will be blurred. The white balance is slightly better than the Magic Blue Note3, and the weak light imaging is more obvious than the Magic Blue Note3. It can only be said that Meizu put the imaging gap of products at different prices very linear
