Will mobile phones replace cameras?

Maybe ordinary home card cameras will be replaced by smart devices one day, but you should know that the quality of photography is not only related to pixels. Early cameras had too low pixels, so improving the pixels obviously helped the image quality. Film is about equivalent to15 million pixels, so it's good to know who had higher pixels in the multi-pixel camera. Now all the cameras are tens of millions of pixels, which means little. CMOS is only one kind of photosensitive element, and different CMOS has different effects. The larger the unit pixel area, the higher the performance, which is one of the reasons for the high image quality of SLR.

Moreover, the resolution of the optical lens is directly proportional to the aperture of the lens, which is why the aperture of the astronomical telescope is more than ten meters, while the physical resolution of the pinhole-like mobile phone camera is limited, so the professional image work of the book still needs a professional camera to complete.

Of course, for ordinary people who don't have high requirements, it is a good thing to combine a camera and a mobile phone, provided that you don't have high requirements for photo quality.
