Every year the new iPhone has few XX doors must not go, this year's iPhone 11 the earliest buyers have also used a period of time, for the camera into the gray, the screen is easy to scratch these problems are different, but about the iPhone 11 photo ghost door is a rare unanimous approval, it seems that this place really can not be washed ...
What the hell is going on with ghost gates?
According to the feedback of many users, when shooting at night, the picture appears to be a central symmetrical reflection of the light source, some are a large area, and some are a point of light. And at present, whether it is the iPhone 11, or 11 Pro, 11 Pro Max, none of them are spared!
In fact, ghost shadows are not unusual for people who often play photography, usually, this is caused by the repeated reflection of strong light in the lens, also known as glare.
Mobile phone lenses and camera lenses, composed of multi-layer lenses, light through the lens of multiple lenses between multiple reflections, the surface of the lens is easy to form reflected light and sensors and other secondary imaging, especially when the lens is not specially coated, and in the case of strong light, ghosting is more likely to appear.
This is determined by the physical properties of the lens itself, and it is indeed difficult to avoid. For mobile phone lenses, the solution to this problem is usually to coat the lenses to reduce reflections, improve the lens transmittance, choose glass lenses with higher cost and better transmittance, and improve lens module assembly technology.
Glare is a common disease, yes, but like this iPhone 11 so exaggerated or the first time, so the "common disease" of this statement must not be said, how did not see the Android phone has this kind of common disease before (in fact, there is also, but not this time the iPhone is obvious)? Or is it that Apple sells 10,000 iPhones, and the lenses used are not as good as those cheaper phones?
But in fact, Apple almost re-bet on taking pictures this time. This generation of iPhone 11 has redesigned the lens module, 11 Pro has also increased to three lenses, and enhanced the algorithm, added a night mode, is this problem because the picture is brighter, the ghost that was not visible in the dark background has become obvious?
This argument is obviously equally untenable, so the cause of the problem can almost be attributed to a design flaw.
iPhone 11 Pro's triple camera was spit ugly at the beginning of exposure, but some people have interpreted that such a design is actually its "clever" place, the three cameras form an equilateral triangle, which can make the three lenses as close as possible, while ensuring that the distance between the three lenses is equal, minimizing the parallax between the lenses, and is also the hardware basis for achieving a seamless zoom of the three focal segments.
Looking at the ghost of the iPhone 11, almost all of them "faithfully restore" the shape of the light source, and it is exactly the center symmetry, that is, flipping up and down left and right. This is reminiscent of the small hole imaging principle of photography, and imaging on CMOS is also the central symmetry of this subject.
Therefore, it has also been speculated that the ghost of the iPhone 11 is part of the light that "returns in the same way" through the lens group, which is cast on the back cover of the lens plane glass, and then enters the lens to CMOS imaging, and the ghost in the picture is the secondary imaging after the light reflection.
So this is probably because of the problem of the new lens arrangement and distance, so why only the dual-camera iPhone 11 also has this ghost? Another reason that can be explained is probably that the CMOS used in the iPhone 11 has a relatively large light reflectivity, or the inside of the glass cover is not done to increase the anti-reflection coating, so many reasons have caused this rollover scene.
How to solve it? Apple has not responded so far
Holding a small ten thousand mobile phone, taking a night scene is this kind of "ghost look", who does not pierce the heart, how to solve it?
For the exposed ghost door, Apple has not responded positively, but according to Apple's tonality, the first batch basically has many problems, and subsequent improvements will be made, such as allowing the upstream supply chain to strengthen the transparency coating, or making adjustments in the assembly process.
As for those who have already bought, they may only hope for the improvement of the later algorithm and alleviate this phenomenon through algorithm optimization. In fact, from the past experience, the first batch of purchased iPhones have been exposed to various problems, in the case of many previous lessons, but also snapped up the fruit fans, should have already made psychological preparations, right?
