Give up 100 million pixels, hahahaha. You may not know that IMX700 is a dual-core focus sensor, and the total number of photodiodes is also 100 million. According to this theory, 12 million pixels is also wrong, because they are all given up. 48 million pixels are also wrong, because sooner or later they will give up. Co-authoring a few pixels is wrong and will give up sooner or later. Just like building a house, you only like the third floor, and then order the construction team not to build the first and second floors. You enjoy the progress of science and technology, but you are unwilling to bear the transition in the development of science and technology. Moreover, this excess is also improving the experience, and it does not cause you any loss. Obviously gave up the Samsung hmx sensor. There is no other reason. It is too old. The 2019 one, although it seems that small negatives can still be easily slinged today, but for the same size, it is more technically acceptable. Unfortunately, the structure is relatively outdated, and the matching optical image stabilization and lens set are too large and expensive. After so many years of popular science in the digital circle, pixels are not necessarily related to photography. Co-authoring is deaf ears. In today’s mobile phone taking pictures is only related to 4 things. CIS, mirror group, algorithm, ISP. I wonder if the essence of 100 million pixels is the number of pixels? If technology permits, if you are happy, you can make a 1/6 inch base with 100 million pixels. Or you can make 100 million pixels with an E symbol, but is that the same thing? The most essential thing left by Samsung’s hmx to history is the outsole. Therefore, the new mobile phone uses Samsung GN2, which is also a big bottom, or even larger. If you don’t have the ability to identify ISP, algorithm, or lens group, the simplest and rude way is to choose the largest sensor. At least the lower limit is here.

CMOS that supports dpd technology actually has two photodiodes under each pixel, which can actually output double pixels, and some people even directly promote x2 pixels (I won’t say who it is). And the derivative technologies such as 2*2ocl and other dpd with quadbayer can actually achieve more pixel output, such as imx689, four pixels share an on-chip lens, quadbayer output 1200w, the highest output can be 4800w. In fact, gn1 supports output 1e, so don’t talk about gn2.

Quad Bayer’s 108MP is a gimmick for mobile phones. The previous praise for the 108MP of the Xiaomi Mi 10 series is not because of the pixel itself (of course his publicity is), but the CMOS size has reached 1/1.3. Xiaomi 11 Pro 5G Snapdragon 888 2K AMOLED four-curved flexible screen 67W without Jingdong ¥ 5699.00 Go to buy​The lens module of the mobile phone can not support 108MP, and the ISP can’t handle 108MP. It doesn’t make much sense. Now I switch to CMOS size. The bigger Samsung GN2 is a good thing, the mobile phone is not suitable for the pixel. Xiaomi 11 Ultra Extreme 5G Snapdragon 888 2K AMOLED four-curved flexible screen Jingdong ¥ 6499.00 to buy​Considering that computational photography relies heavily on computing power, the current output pixel is actually controlled at 12-16MP. If you want to play 108MP, it’s only suitable for cropping zoom, but you can’t use Quad Bayer.

Whether it is to use 100 million large pixels or a larger background, the ultimate goal is to obtain better quality imaging results. 5000w supports Xiaomi’s self-developed night owl algorithm. Under low light conditions, the amount of light entering directly determines the imaging positioning effect, and the amount of light entering the outsole is more sufficient. GN2 sensor, 50 million pixels, 1/1.12 inch sensor area, unit pixel 1.4μm, supports four-in-one pixel, so that the unit pixel area can reach 2.8μm. HMX sensor, 108 million pixels, 1/1.33 inch sensing area, unit pixel area of 0.8μm, support for nine-in-one pixel camera hardware is the foundation, good foundation, can only be said to win at the starting line, affecting the final imaging The effect is also the image processing chip, that is, ISP, and its own Al algorithm. 9-in-1 is more difficult to process than 4-in-1. I guess Xiaomi’s self-developed surging C1 ISP with a 100-megapixel sensor is still under pressure.

Most of the answers didn’t reach the point. The original intention of using 100 million pixels is to have a large bottom and replace the telephoto at the same time. If you carefully study the machine that Xiaomi has released in the last six months, you will find it. Mid-range cameras without telephoto lenses, but with better positioning and taking pictures, all use 100 million pixels (such as redminote 9pro, k40 supreme, millet 11). The camera with a telephoto lens basically does not use 100 million pixels, but uses a larger bottom than 100 million pixels (such as Xiaomi 11pro, Xiaomi 11 Extreme). In a mobile phone without a telephoto lens, the crop of 100 million pixels can make up for the lack of a telephoto lens to a certain extent. This is the real use of 100 million pixels. As for why Xiaomi 10pro and cc9 have both telephoto and 100 million pixels. On the one hand, it was indeed a gimmick, on the other hand, could you still find a base larger than 100 million pixels for Xiaomi at the time? Therefore, it is inevitable that the previous Xiaomi flagship machine uses 100 million pixels. It is inevitable that the current Xiaomi flagship machine does not need 100 million pixels.

Xiao Yudi thinks that the first Samsung GN2 super-outsole sensor is not a good marketing, a lens jointly developed with Samsung at a cost of 100 million yuan. It can not be said that Xiaomi has made great efforts in taking pictures, making up for the shortcomings of the flagship mobile phone camera part, better highlighting the strength of the Xiaomi 11pro Android phone king, and the strength of the Xiaomi 11Ultra Android Light, which is better based on the high-end market. If you use the previous Samsung HM series 100-megapixel lens, how can you highlight the advantages of taking pictures? How can it be called the Android machine king, or even the light of Android, doesn’t it seem too monotonous and old-fashioned? Although the 50 million pixels of the GN2 sensor is not comparable to the 108 million pixels of the Samsung HM series, this sensor brings a larger sensor size, and the single pixel area reaches 1.4um, which is larger than the 0.8um of the HM3. It is a four-in-one The technology can reach 2.8um, the lens has a larger amount of light, and with the dual pixel enhancement technology, the night scene performance is better, and the focus is faster when taking pictures. Xiaomi 11pro has the blessing of Samsung’s super-outsole GN2 sensor this time, coupled with the night owl algorithm, the overall camera strength is greatly improved, the night scene performance is excellent, and the objects taken are close to what the naked eye can see. Samsung GN2 sensor can also output 100 million pixels. Naturally, there is no need to say that the picture definition can improve the night scene performance. Naturally, it is better than Xiaomi 11 taking pictures. This time, the Xiaomi Mi 11 Pro is equipped with Samsung GN2 sensor, coupled with the night owl algorithm, the night scene performance is greater than that of the Xiaomi Mi 11, the noise is well controlled, the color performance in low light is natural, and it is comfortable to see. This time, it is equipped with the jointly-developed Samsung GN2 sensor, which really shows that Xiaomi has made a lot of effort in taking pictures, and it also allows Xiaomi’s flagship mobile phone to gain a foothold in the high-end market. It is no longer the millet that ignores self-developed technology in addition to stacking materials.

What was the original intention of 108mp? Pure high-resolution? Then I tell you, if you use 108mp when the light is bad, it will be a disaster, because the amount of light is too little, and it is all noise. Xiaomi uses 108mp for all-in-one pixels. Under the premise of four-in-one pixels, it not only guarantees sufficient light input, and even in the case of four-in-one, the effective pixel number can still be around 25mp, which means that compared with After the Huawei Imx600y four-in-one 10mp, Apple’s ancestral 12mp, Xiaomi can still retain very good resolution, and the detailed imaging can be guaranteed.

In 2019, Xiaomi released a Xiaomi CC9Pro. The cowhide of this phone is: Xiaomi CC9Pro has five rear cameras: 100 million pixel ultra-high-definition lens + 20 million pixel ultra-wide-angle lens + 12 million pixel portrait lens + 5 million pixel The ultra-telephoto lens + macro lens is such a group of images that directly tied the Huawei Mate30Pro ranking first on dxomark. Here is a mid-range processor: Snapdragon 730G. This set of image modules is the best set of image modules that Xiaomi could do before February 2020, and it was copied directly to Xiaomi 10Pro. Xiaomi 10Pro rear four cameras: 100 million pixel ultra-high-definition lens + 20 million pixel ultra-wide-angle lens + 12 million pixel portrait lens + 8 million pixel ultra-telephoto lens. Replace the processor with Snapdragon 865 and the telephoto lens with 8 million Pixel, in the last time dxomark directly surpassed Huawei Mate30Pro as the first place for almost a month. Therefore, the biggest effect of the 100 million pixels here is: gimmick + surpassing Huawei’s performance. This year’s Xiaomi Mi 11 Pro gave up the 100 million pixel camera. The reason can be very simple. It’s okay to use the same gimmick once or twice. , So it changed to another direction: the outsole sensor, “the bottom of the big one crushes people.”

The high-pixel mobile phone isp can’t carry it, and it is too bottom, the resolution index drops when the light is slightly darker. From the replacement of Mi 10 to x50pro+, I can say that if there is no resolution to crush the Mi 10 mobile phone, I will not buy a new mobile phone for the purpose of imaging. When hmx was changed to gn1, I can clearly say that the resolution dropped sharply. Although the actual resolution of hmx is far less than 100 million, it is already much higher than others. Resolution power is not strong from low to high, but from high to low it is really too strong. Of course, on mobile phones, computing is king. In fact, I posted pictures of hmx and 363 separately. You should not be able to judge the high resolution at a glance. Last year, the highest resolution on mobile phones was the 5000w imx700. But the sampling capability is far inferior to hmx. Algorithms on mobile phones can really change their lives. Just looking at the bottom is actually useless. There can only be a lower limit of the raw level. If you can install a Google camera, it can be rescued, and it can take off directly to the first-line level with a saber. (Including photos only) Therefore, the pursuit of resolution on mobile phones and the development of higher resolution algorithms have a future. The background of hmx should be rarely used by major manufacturers in the future.

Lei Jun also said that the more pixels, the better. But in order to let more people pay attention to Samsung’s lens and the progress of Xiaomi’s camera, they can only pick the 100 million pixel gimmick. Although he also has a 1.33 outsole, how many people knew the bottom? But after 100 million pixels came out, some groups spared no effort to use as many popular science pixels as possible. The bottom level was crushed to death, and they spared no effort to black out 100 million pixels. The knowledge of all consumers has been comprehensively improved. Everyone has the concept of the bottom, so now Xiaomi mainly promotes the 1.12 bottom. What else are you dissatisfied with?

Because this main camera was pitted by Samsung, it’s not easy to use. 100 million pixels. The area of a single pixel is too small, it is almost impossible to hold a photo in a low light environment, and the photos taken are almost all blurry. Even if it can support the pixel 4-in-1, the amount of light input is still not as good as Samsung’s own 9-in-1. In general, except for a sunny day, the photo experience is really not good, basically it is just a scanning lens.
