In recent years, the most important function on smartphones, the most important function of manufacturers, is to take pictures.
Major mobile phone manufacturers, especially domestic mobile phone manufacturers, like in the competition, in the mobile phone photography is full of energy, from the algorithm to the hardware, constantly improving.
DXOMARK has made a lot of money because DXOMARK's camera evaluation is for money, and domestic machines, especially Huawei and Xiaomi, continue to send tests and constantly send them money.
When the domestic machine is taking pictures, Apple does not seem to be so hard, the ranking on DXOMARK has long been surpassed by Huawei and Xiaomi, and the latest and most expensive iPhone 13 Pro Max can only rank fourth, not as good as Xiaomi and Huawei.
Recently, we even found that the iPhone13 series, when taking pictures in low light, the phenomenon of "ghosting" even exists. In fact, since the iPhone 11 series, people on the Internet have frequently revealed that when their iPhone is shooting at night, the reflection and glare of other scenes will appear on the screen, just like "ghosting".
Then the question comes, such an obvious "ghost", why apple can not solve, from the iPhone 11 to the iPhone 13, are already 3 generations, or can not be determined?
Let's first talk about the formation principle of "ghost shadow", which is a "glare" optical phenomenon, that is, the light rays pass through the lens of the camera, reflect in the lens and produce light and shadow, and then captured by the CMOS sensor.
Even before the iPhone 11, there was, but before Apple's night shooting function was not strong, everyone found less, iPhone 11 began, Apple attached importance to night shooting, so more and more people found.
In fact, not only Apple has, other Android machines also have the same, like Xiaomi, Huawei, OnePlus, Samsung, after all, the "glare" event, as long as it is an optical lens, it can happen.
It's just that the ultra-wide-angle lens that Apple added in the iPhone 11Pro is almost the widest ultra-wide-angle lens in the mobile phone industry, the viewing angle range is larger than that of Samsung Huawei, and the picture that can be accommodated is much larger, so the glare will be much stronger, so it is more obvious.
So is there a way to solve this problem? In fact, there are, such as domestic machines have been trying to find ways to solve this problem, like Huawei, VIVO, etc. have been trying to find ways to add coatings on the lens, that is, a film, and then cooperate with the algorithm to finally remove the "glare".
I believe that in the follow-up, Apple will also follow up this technology, first using the "coating" to reduce the "glare" phenomenon, and then using the algorithm to remove the "glare" that has been formed in the photo, but perhaps in Apple's view, this phenomenon is not so serious, so it is not too serious to engage.
