You can use any number of tricks of computational photography or various software “enhancers” of photos and videos, but nobody canceled the laws of physics: all other things being equal, the more the image sensor is used in the camera, the higher the quality of the photo, especially in low light conditions. The photo below gives a clear idea of how much the sensors used in modern flagship smartphones differ in size. Despite the fact that on paper, their characteristics may be close.
On the left is the Sony IMX689 image sensor used in the OnePlus 9, and on the right is the Samsung ISOCELL GN2 sensor used in the Xiaomi Mi 11 Pro and Mi 11 Ultra. On paper, the difference in resolution and optical format does not seem significant: 48 megapixels and 1 / 1.43 inches in the first case and 50 megapixels and 1 / 1.12 inches in the second. But in reality Samsung ISOCELL GN2 is much larger, and, of course, it is able to provide a better picture than sensors of a smaller optical format.
Recall that Xiaomi Mi 11 Pro and Mi 11 Ultra will be the world’s first smartphones with an image sensor Samsung ISOCELL GN2. The official premiere of these models will take place tomorrow.
