I have to say that the camera function of smart phones is getting better and better now, with pixels ranging from 20 million to 40 million to 1 100 million. Not long ago, it was reported that Xiaomi's next generation flagship machine will adopt 200 million pixels. Tut tut, it seems that these bosses in the Android camp are also taking pains. # Highlights of digital technology #

Even more frightening is that when a single camera can't meet the needs of consumers, mobile phone manufacturers begin to use multi-camera superposition to improve the image quality. In just a few years, it is not uncommon to take two photos, three photos, four photos and five photos ..... and it is no longer exclusive to high-end machines. Even the cheapest entry-level models are equipped with multiple cameras.
Glory Magic3 series is equipped with ring five cameras.
Now, smartphone cameras seem to have a new trend-towards a larger aperture.
First, explain what an aperture is. Simply put, it is to control the aperture size of light entering the camera. The larger the aperture, the more light enters. At the same time, the larger aperture can also reduce the image blur caused by lens movement or hand shake, and enhance the effect of optical image stabilization to some extent.
As we all know, aperture is an accessory of digital SLR. What will happen with a mobile phone? No, Samsung was the first person to eat crabs.
As early as 20 18, Samsung introduced the "Galaxy S9" equipped with a variable aperture camera, which adopted the intelligent variable aperture of F1.5/F2.4. After taking dark photography with a large aperture, the amount of light entering was significantly improved. It is said that the effect killed the popular model iPhone X at that time.
At that time, because the sensor of the smart phone was too small, but the aperture structure was too large, Samsung finally gave up the design and used the outsole camera, such as Samsung S2 1Ultra released by flagship machine last year, after sticking to two generations of models, such as Galaxy S 10 and Galaxy Note 9 series.
But now, the variable aperture returns, or Huawei comes out.
A few days ago, it was reported that Huawei Technologies submitted a patent to the World Intellectual Property Organization, which described in detail how Huawei intends to equip future smartphone cameras with variable apertures to improve shooting quality.
According to the patent description, Huawei hopes to use the same blade design as the camera and place at least six aperture blades on the rear camera module. These blades can slide with each other, thus overlapping to produce a larger aperture. By driving motors and coil magnets, it can control and adjust the amount of light entering the camera.
At that time, the aperture blade on the sensor will be opened when necessary to get as much natural light as possible, and it will also be reduced when the light is sufficient. In terms of technology, compared with Samsung, Huawei's variable aperture structure design is more complicated.
In order to make the public understand this technology more intuitively, graphic designer Technizo Concept has produced a series of 3D renderings based on Huawei's patented drawings.
As can be seen from the rendering, the front adopts a full-screen design, equipped with an off-screen camera, and the screen coverage is very large. As for the back, it is still the same star ring shape as Mate 30 and Mate 40. I have to say that this unique recognition can be recognized at a glance.
But the difference is that the main camera of iris is placed in the middle "C position". As described in the patent drawing, the variable aperture lens designed by Huawei seems to have six blades arranged in a "circle", and the aperture range will obviously be different, but the specific range is still unclear.
In addition, due to the limited internal space of the mobile phone, it is impossible to accurately control the iris, so Huawei Iris only supports two gears to switch back and forth, just like Samsung. But the difference is that Huawei's variable aperture is to adjust the amount of light entering the camera module by cooperating with the shutter, which brings multi-step adjustment function and looks more like the traditional camera aperture.
I have to say that this technology is really "extravagant"! However, the emergence of patented technology does not mean that Huawei will really equip smartphones with variable apertures in the future. However, as a consumer, I still hope Huawei can realize this idea. After all, the quality of camera photography has improved, and the experience is naturally very different.
