Why is Apple's mobile phone only 8 million pixels, but the photos taken are better than other mobile phones?

The camera of Android phones basically starts at13 million pixels, and even reaches 20 million pixels in flagship machine. Even all kinds of black and white dual cameras and color dual cameras are dazzling.

On the other hand, the previous generation iPhone iPhone 6 is still 8 million pixels, but the camera effect is not necessarily worse than that of 2/kloc-0.0 million pixels camera.

In fact, the pixel is not the decisive factor of the photo effect, and the pixel height does not necessarily mean that the photo effect is good. Pixel refers to the largest pixel photographed by the camera. Take13 million as an example. The biggest photo it took was 4208x312013 million.

It is the camera sensor that determines the quality of taking pictures. For example, shoot the same place with two mobile phones, one is16 megapixel Android phone and the other is 8 megapixel iPhone.

In the two photos, if we only compare the original pixels of 100x 100, we will find that the photos taken by Apple are much clearer.

The camera system is also important. Apple's iOS system is unique to Apple, and it is easier to optimize the various performance of the camera (shutter delay, focusing speed, etc.). ). Moreover, Apple has worked hard in the field of image processing software for many years, and its white balance, sharpness and noise processing are also first-class in the industry.

On the other hand, Android, many manufacturers focus on how to buy the best sensor, but the energy invested in camera algorithm is seriously insufficient, and they do not pay attention to software optimization at all. There will inevitably be problems with the focus and white balance of finished mobile phones.

Of course, this does not mean that high pixels are useless. Because of the high pixels of photos, this means that users can cut photos more freely without worrying about the loss of details. Similarly, high-pixel cameras can even achieve lossless zoom. Although the zoom factor is only 3~5 times, it is better than lossy zoom.

Therefore, since the iPhone 6s, Apple's rear position has been upgraded to1200,000 pixels, and the camera performance has been further improved.

These are some photos I took on Red Rice 2. Please have a look.

It is mainly a technical problem, which has considerable technical content compared with the optimization of software and the collocation of hardware; This is also a fundamental reason why Apple's mobile phone configuration is not high, but the price is high.

There is also the problem of the system. The mainstream systems of mobile phones are Apple's IOS system and Android system. Compared with the hardware configuration of Android phones and Apple's software optimization, Apple's software and hardware collocation is more reasonable, which is why it can become the leader in the mobile phone industry.

And the awesome algorithm of Apple's mobile phone camera. In fact, what exposure parameters should be used, what white balance should be used, which parts need to be brightened, which parts should be dimmed, and so on. For a certain picture, these are all determined by the mobile phone through calculation and analysis. The program in this respect is the algorithm. To use an inappropriate metaphor: Apple's IOS system has a perfect understanding of mobile phone photography.

A simple metaphor is: the difference in production efficiency between a large group of slash-and-burn people in primitive society and a person in today's social mechanization environment!

Compared with Android phones of the same level, Apple phones have always been pixels, and even mid-range mobile phones are called 1500W pixels or even 2000W pixels. Iphone has always been 800W pixels, and now even the strongest iPhone is dual 1200W pixels. It can be said that Android phones boast much higher pixels than Apple phones.

There is actually a misunderstanding. When you buy a mobile phone and look at the camera, you always say the number of pixels in the camera. In fact, pixels are not the decisive factor in taking good photos. The most important things are cameras, sensors and software algorithms.

There are only a few companies that make mobile phone sensors. Of course, the most famous is Sony's camera sensor. Similarly, many domestic mobile phone manufacturers buy Sony sensors, including many flagship machine. Similarly, Apple's sensors are basically Sony's sensors. So why are all the sensors from the same mobile phone manufacturer? So why is there such a big difference?

In fact, the quality of photos taken by mobile phones is different not only in hardware, but also in software, that is, the adjustment level of mobile phone manufacturers for their mobile phones, including cameras, picture colors and so on. This is my own housekeeping skill for Apple, and I am also good at camera tuning, especially my own developed iOS system, which is more comfortable to tune. In contrast, we all know that camera calibration and even software optimization can not be achieved overnight by one manufacturer in a year or two, but a long-term accumulated technical advantage. Similarly, we all know that many Android mobile phones, especially domestic mobile phone manufacturers, are just emerging, and there are still shortcomings in software tuning. So we should focus on the adjustment of software.

Let me talk about pixels. The hardware of Apple's mobile phone is upgraded every year, but its camera remains unchanged at 800w pixels. Although there are many complaints from the outside world, in the eyes of most consumers, Apple's 8 megapixel lens still provides them with the best photo effect. Far better than many photos taken by Android flagship machine.

I think there are three main reasons: 1, hardware design; 2. Software algorithm; 3, fruit powder belief. Let's explain one by one:

1, hardware problem.

Apple's camera is customized by Sony, and Apple is deeply involved. It has super high resolution, linearity and large dynamic range. And if the fever is large, it will also affect the pixel quality of the mobile phone. The design of iphone is exquisite, far from the design of most mobile phones in supermarkets, so the design of the whole machine is very hot. This also created the camera pixels of Apple's mobile phone.

2. Niu x algorithm.

Do you know what an algorithm is? The so-called algorithm actually refers to what exposure parameters, what white balance should be used for a certain picture, which parts need to be brightened, which parts should be dimmed, and so on. These are all determined by the mobile phone through calculation and analysis. The program in this respect is the algorithm. To put it bluntly, it is the ability of mobile phones to understand photography.

The reason why the algorithm is the final battlefield of mobile phone manufacturers is because our mobile phone photography is jpg, a raw file that can truly reflect the strength of camera equipment, which (almost) does not exist in the mobile phone photography market that emphasizes convenience and randomness.

Therefore, the gap between software and hardware is completely different. The imaging quality of Apple's 800w pixel is higher than that of many 1300w Android phones.

3, of course, is the belief of fruit powder.

Jobs said that a 3.5-inch screen is the best feel. Let's see how many such mobile phones there are now. Even Apple has abandoned the small-screen mobile phone and started to use the big-screen mobile phone. Moreover, the effect of high-pixel mobile phones such as 800w pixels is difficult for ordinary people to recognize with the naked eye. Therefore, fruit powder certainly thinks that the pixels of Apple 6 are good, which is better than all other photos. In fact, the image quality of iphone6 is indeed better than that of general flagship machine, but it is not necessarily the best.

All the above photos were taken in 6s or 7s. Ask Android mobile phone users to communicate with each other.

Optimize, okay? The Android phone is nominally 20 million. In fact, the shot picture is also compressed, not the original picture. Whether it is an Apple or an Android phone, the image data transmitted through the camera sensor must be processed before the user can get a photo, and this intermediate processing is technology.

As we all know, ccd is a manufacturer of mobile phone lens sensors, and there are only two or three in the world, so the hardware technology of cameras on our mobile phones is similar.

You can see that Apple's mobile phone has several characteristics. At present, the first product line ranges from the 6th generation to the total number of X products *** 10, while Apple is rich in manpower and focuses on product details optimization for so many products. It has time and manpower, so it is a few blocks behind the Android phone with the same hardware parameters.

Of course, hardware performance is an undeniable hard standard. If we compare the 800w pixel Apple phone with the 2000w Android phone, the Apple phone still has some shortcomings. The simplest thing is to zoom in. 2000w pixels can zoom in without noise, but 800w can't.

Not much, actually it's all about image processing. Photographers can shoot SLR effects with their mobile phones. Many of them are similar problems.

After reading some people's answers, none of them got to the point. For the sake of clarity, the length is slightly longer.

1 is the maximum resolution of human eyes. On a mobile phone with a six-inch screen, only 1 ten thousand pixels can be distinguished. When sliding the screen to enlarge this part, the magnification is five or six times, that is, 5 million to 6 million. Considering that personal eyesight is super strong, 8 million pixels can't be distinguished by other people's eyes at all.

2. According to the national standard, the resolution of the central part of the excellent photographic lens is 74/mm, and the lens with the resolution of 120/mm has been seen internationally. The mobile phone lens is definitely not as good as the camera lens. The horizontal resolution of the 8-megapixel mobile phone sensor has reached nearly 500/mm, and the lens can't be competent for any higher pixel, and the 2000-pixel lens can't help much.

3. The general area of mobile phone sensor is 1/2.5 inches, about 5 4mm, and the size of each pixel is 2.5um, 8 million pixels. , 20 million pixels, each pixel size is 1um? It can be seen that each pixel of 8 million mobile phones is 2.5 times that of 20 million mobile phones, and it also gets 2.5 times the light. If you get more light, the picture quality will be better. High contrast, rich colors, people's eyes can see clearly.

4, mobile phone manufacturers, all understand this truth, but also desperately improve pixels? Because mobile phones are commodities, profit is the core. Most people in China think that pixels are high and images are clear. Another point is that in the case of good light, the number of pixels and the quality of photos are not easy for people's eyes to distinguish, so it is against science to cater to people's wishes and publicize traffic in advertisements. This situation has emerged.

Apple's market is not only in China, but also in a large number of western countries. The people in these countries have a high level of knowledge, so our bluff doesn't play much role. Therefore, Apple respects science and does not engage in commercial gimmicks.

From Lenovo to Huawei, I have been using domestic mobile phones, not excluding foreign brands, just making a phone call and taking some photos. The requirements are not high, that is, whoever can afford it is convenient to use after sale. Now I'm using Huawei P9, and I feel I can be a backup camera.

The following photos were taken with P9 a few days ago.

Why is Apple's mobile phone only 8 million pixels? However, the photos it takes are better than some mobile phones! Why is this? In fact, we see the current Apple mobile phone with a rear lens of 1.2 million. The 8 million pixels we are talking about should be a mobile phone like iPhone6.

However, you should also be surprised. Now the mobile phone has reached a million pixels. Although Apple only has1.200 million yuan, its photo performance is recognized by consumers. What caused it?

The first thing to know is that Apple's image capability is highly optimized. Although you can't see higher pixels on Apple's mobile phone, I believe that for consumers, we can feel the performance brought by Apple.

You should know that the optimization of the algorithm is actually the basis for Apple's mobile phone to take better photos. Moreover, many mobile phone manufacturers have introduced mobile phones with higher pixels. Although they can really improve the camera ability of mobile phones, their performance is actually not as good as that of Apple without better optimization.

Moreover, the pixels of the mobile phone itself are not the decisive factors that determine the clarity and performance of our photos, but also include photosensitive elements, image signal processors and so on.

You will find that the photos taken by Apple's mobile phone are very clear, and one of the key factors is that Apple's mobile phone will not make the photos more beautiful. So the photos taken by Apple phones are very real, which is why you can see what you see on your own Apple phones.

Similarly, Apple's screen optimization is also very high. In this case, the better the performance of the screen, the better the effect of restoring the photos taken by the mobile phone.
