Recently, a new batch of entry-level smart phones have emerged in the Android smart phone market. Some models are more awkward in positioning. They are a little more expensive than the 1000 yuan phones, but 500~600 yuan less than the 2000 yuan flagship. In this issue, we use several popular entry-level phones on the market to take photos and make horizontal reviews, which are Yijia Mobile X, Xiaomi Mobile 4c, Nut Mobile Meilan metal, the problem is Which one is better at photography?
Specifications
Xiaomi Mobile 4c Query Sensor Results
In terms of configuration, these four mobile phones all use 13 million main cameras, and all of them use phase focusing except nut mobile phones. Meilan metal and Yijia mobile phone X use Samsung sensors, model S5K3M2, which belongs to Samsung ISOCELL. Xiaomi mobile phone 4c officially uses two different sensors, one is Samsung S5K3M2, and the other is Sony IMX258, After inquiry, the Xiaomi mobile phone 4c on hand is Sony IMX258, but the nut mobile phone cannot confirm its specific model. According to the information on hand, it can only be said that it is most likely Samsung S5K3L2.

In the first set of daytime scenes, in terms of white balance, Meilan metal>Nutphone>Xiaomi mobile phone 4c>Yijia mobile phone X, while in terms of analytical power, Xiaomi mobile phone 4c>Nutphone>Yijia mobile phone X>Meilan metal, Meilan metal causes uneven light lines in some red buildings due to the background, and Meilan metal's painting algorithm has injured some details of red buildings by mistake, Some of its details seem to be covered with a layer of fog, while the nut phone is overexposed on the white ground, which is too white to see the texture of the floor tile. In this group of samples, Xiaomi mobile phone 4c has the best comprehensive performance.

In this set of backlight daytime samples, in terms of white balance, we can see that the white balance of the nut phone is significantly different from the other three phones, and the whole picture is purple. In terms of analytical power, we can see that the nut phone is 100% of the original picture, The leaves in the nut mobile phone have been pasted into one piece. The leaf outline of Yijia mobile phone X is the clearest, followed by Xiaomi mobile phone 4c. In this group of samples, Yijia Mobile X performs best.

In this group of scenes, in terms of white balance, these four mobile phones are very similar, which can restore the real scene well. In terms of color, the best color of potted leaves is Xiaomi 4c and Nut mobile phones. However, we can see that these four mobile phones are overexposed in the leaves. In this respect, several mobile phones are not ideal.
To sum up, in the daytime scene, Xiaomi 4c and Yijia Mobile X perform better, while Nut Mobile is the worst.

In this group of ultra weak light scenes, we can see that there is a large point light source at the construction site, which can test the anti glare ability of the three machines. We can clearly see that the most serious glare is the nut mobile phone. In the previous evaluation, we also said that the nut mobile phone has a common glare problem, and the Xiaomi mobile phone 4c also has serious glare, In terms of anti glare, Yijia Mobile Phone X>Magic Blue metal>Xiaomi Mobile Phone 4c>Nut Mobile Phone.
It should be noted that if the camera lens is dusty or dirty when taking photos, the glare probability is very high. As a result, the lens must be wiped clean when doing glare tests, and cotton clothes can be used.

summary
To sum up, these four machines do not have optical anti shake, so their performance in night imaging is very ordinary. Under automatic photography, they increase the ISO/shutter time to improve the picture exposure, which will bring two problems. One is that noise is not easy to control, and the other is that the picture is easy to paste. At this time, algorithm optimization is particularly important. Through appropriate smearing algorithms, Improving the picture purity can effectively reduce noise. In daytime performance, their analytical power is similar. The difference is mainly in the white balance. The best comprehensive performance is Xiaomi mobile phone 4c and Yijia mobile phone X, while the worst performance is nut mobile phone. Especially at night and with a little light source, nut mobile phone basically says goodbye to taking pictures.
