Charm Blue U20 is the most low-key machine in the Meizu history, some users may be curious, this parameter is quite mysterious, and even the official website has no cell phone, what will happen to its pictures?
In order to better measure the charm blue U20's photo performance, we used to locate the slightly higher charm blue E (Sony IMX258) and Charm Blue Note3 (model unknown) as a comparison, three Meizu thousand yuan are 13 million pixels sensor , support for phase focus, f2.2 wide-angle lens, settings are very similar.
The Samsung Galaxy Note5 as the top flagship standard sample appearance, we can understand the huge gap between the flagship and the thousand-level photograph. The imaging features are excellent in resolution and sharpening, and there is a clear trace of white balance (particularly in cafes and other warm lighting). The noise control is normal, and the details of the dark parts of the extremely low light and large light difference scenes have special white fine noises. The overall strength is now also the top few.
The core of mobile phone photography is the camera experience and imaging effects. The main impacts are:
Speed , including focusing speed, shutter response, imaging speed;
The rate of filming, the probability of hand shaking and filming;
Automatic degree , can identify large light difference and low light scene, automatically trigger HDR and night scene mode;
Ease of use , whether the frame has delay/smear/drop frame/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 daylight/light/weak light and extremely low light, whether the white balance (screen color wind direction) and the degree of lightness and darkness can approach the naked eye;
Discrimination and power can be roughly understood as sharpness. At the same time, the sharpness, detail and naturalness of the picture can be taken into consideration.
Tolerance , that is , the ability to simultaneously show the details of the shade, for the mobile phone, this is basically equivalent to whether the HDR effect is natural and harmonious, whether there is ghosting, white balance deviation and the decline of resolution and other issues after the synthesis;
The remaining assessments include noise control, color saturation (the closer to the naked eye the better, but Samsung and Huawei will be able to increase some of the recent, in order to please the user's eye), lens quality (including edge deterioration control, anti-glare, atomization Control, wide-angle and pillow-type distortion control, etc.) and many other things.
Although everyone's requirements for the photo experience are almost the same, the proportion of different items for imaging is completely different for different users: for example, the number of Mao who likes to enlarge photo scans will definitely put the power of resolution first. And the proportion is very high; the circle of friends in the sun has a special focus on latitude, white balance, saturation and other items, but the demand for resolution is not high. Therefore, the comparison will be based on different project segments, and everyone will focus on understanding what they care about.
Photo experienceCamera interface and smartness: The camera interface of the three Meizu thousand-thousand-thousand-thousand-dollar machines is exactly the same, and it is of a minimalist type, with good ease of use. There is an automatic night scene, but the HDR should be manually opened, with a general degree of intelligence
Shutter response, imaging speed, HDR and night scene processing speed: Charm Blue Note3 There will be a few seconds of view pause after pressing the shutter. The other two machines have no such problem. The charm blue U20 imaging speed, HDR, night mode and Charm Blue E are very close, the latter two time-consuming close to 2 seconds faster than the charm Blue Note3, but there is still a distance and the flagship.
Focusing success rate and filming rate: Charm Blue Note3 and Charm Blue U are both remarkable performances. Even though there are obvious pull bellows under very low light, they can successfully coke in the end. But the most expensive Charm Blue E auto focus will have a certain probability of out of focus, manual metering is very sensitive, it is easy to overexposure.

The big manufacturers that can compete with Xiaomi's HDR on the market are left with Meizu, and the two domestic big names have yet to adjust their own HDR algorithm. Charm Blue U20's HDR algorithm effect and Charm Blue E, Charm Blue Note3 and other predecessors, still no improvement.
Meizu HDR is characterized by a clear increase in the details of the shadows, but it is also overly bright on some occasions. The color temperature adjustment is not heavy, but the green saturation will be seriously affected, and the sense of oil painting is very heavy. The availability of HDR is even lower than that of Xiaomi's home. It is a level that is completely not recommended.
Lens quality & wide angle
Although it is 13 million, the proofs of Charm Blue U20 are slightly smaller. But in terms of wide-angle, Charm Blue E is smaller than Charm Blue Note3 and Charm Blue U20. In exif, the former is 3.46mm focal length, and the latter two are 3.5mm focal length.
Equal magnification
Meizu is one of the most popular among all mobile phone manufacturers. While 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 these two years are almost such wide-angle range.
A wide-angle lens will have a noticeable effect when shooting at close range. The range of scenes recorded within 2m distance is several laps larger than that of Note5 with a 28mm equivalent focal length, while the distance above 10m is slightly smaller. In addition to the gap between 1600 and 13 million pixels, such as 10m distance shooting scene zoom, the size of the scene is very obvious, but also destined to Charm Blue or even Meizu series will not be too good.
Of course, wide-angle is not without advantages. It allows the user to take pictures easily. A photo captures more things. This is a problem for manufacturers. Only in the perspective of wide-angle and analytical power, the author is more optimistic about the tendency of discrimination. After all, many times when the camera scene can not fit, you can also back a little before, but the loss caused by the lack of analytical power is beyond the user's own control.

The lowest price Charm Blue Note3, its imaging level is also significantly behind other mobile phones, white balance floating out of the edge, there will be irregular green and yellow issues of varying magnitude. The quality of the lens is poor, even if it is covered with a layer of gray during the day, the edge of the scene is blurred, and the power of analysis and analysis is miserable. If the light is weaker, it will be mad at ISO and smudges. The noise control is good, but the details are not much left. The overall level can only record the outline, even if it is used to scan the two-dimensional code, the light should be better.
Charm Blue E uses a smaller, wider-angle lens and is the first machine in the Meizu flagship series to use the Sony IMX sensor. The imaging performance is also the best of the three charm blues. Sensual generalization is that 3 positions are better than Charm Blue Note3 and 2 are better than Charm Blue U20. White balance is blue-green, but the magnitude is acceptable. Daytime resolution power is the normal 13 million sensor level, low light noise is also the best a charm blue.
The charm blue U20 is a very compromise product, sandwiched between the charm blue E and charm blue Note3, but closer to Charm Blue Note3, the actual imaging is still relatively disappointing, the overall is just slightly better than Charm Blue Note3. The lens limits the quality of the general, even during the day, the limit details will be ambiguous. White balance is slightly better than Charm Blue Note3. Low-light imaging is more obvious than Charm Blue Note3. It can only be said that Meizu has made the imaging gap of different price products very linear...
