There is an old saying in photography that the best camera is the one you have now. In recent years, the photography level of smart phones has soared, and the imaging of mobile phones has become better and better, gradually occupying the market space of card cameras. Then the question arises, which is the strongest camera phone now?
Foreign evaluation institutions Take the iPhone 6s Plus Nexus 6P、 Samsung Galaxy Note 5, LG G4, Moto X Pure Edition (the hardware is the same as the Moto X Style of the national travel version) and HTC One A9 are compared for photos. Now let's see the results.
PS： There are some differences in the evaluation standards of cameras at home and abroad, so the author re analyzed the samples. Click the picture to view the large picture.
parameter
The data that most affects the image quality is the size of the unit pixel. In the photographic world, "the bottom is bigger than the bottom" means it. The larger the value, the better the tolerance of weak light imaging (the ability to accommodate light and dark details at the same time).
The second is whether optical anti shake is supported. Although there is a more obvious problem of edge image quality degradation for Guan Xue anti shake models, the weak light imaging quality will be greatly improved. The smaller the aperture value is, the greater the light input of the lens is, and the better the weak light imaging quality is.
The equivalent focal length will affect the field of vision of the image. For the same sensor, a small value will result in a wide field of vision, but more scenes will be squeezed out per pixel, which will affect the discrimination.

Shutter and ISO information
IPhone is confident in optical anti shake, with the slowest shutter and the lowest ISO; Other Android machines maintain 1/30s-1/20s shutter to ensure the film rate, so the ISO is higher than that of the iPhone, and the power of high pixels cannot be exerted between 200-300. It was found that the Moto X Style without optical anti shake has raised the ISO to 400.

Summarize daytime performance:
The best comprehensive performance in the daytime is Note5 and Nexus 6P. The former has better discrimination and white balance; The latter has higher contrast and saturation, which is more pleasing to the eye;
G4, Moto X Style and iPhone 6s Plus are inextricably linked: G4 is also very discriminative, but the metering is often slightly bright, and the picture contrast is not enough; Moto X Style has the strongest limit discrimination, but a little poor light will affect the performance; The iPhone 6s Plus is balanced in all aspects, but there is no special project;
HTC One A9 is far away from other machines in terms of white balance and discrimination.

Summarize weak light performance:
Nexus 6P and Note5 perform better. The former performs better in noise control and tolerance, but the white balance is not accurate; The latter is weaker in discrimination, but more accurate in white balance;
The second is the G4 and iPhone 6s Plus. The former has better discrimination, better light measurement, and better control of image lighting details and noise; The next level is HTC One A9;
However, Moto X Style has the worst performance, the smallest unit pixel size, and the absence of optical anti shake, making its weak light performance largely abandoned by other machines.
PS： The extremely weak light scene that we most care about by the Maoist Party did not appear, so we can not compare
