But the difference is that this year's two high-end models may add an "ultra-wide-angle lens" to the previous "wide-angle lens long focal lens" to form a new "three-shot" system. If this rumor comes true, it's new this year.IPhoneThe camera configuration will be the biggest upgrade of the iPhone camera in three years since the first dual-camera launch of the iPhone 7 Plus in 2016, which will bring more "iPhone Photography" imagination space to many ordinary consumers, especially photographers.

In retrospect of the history of the iPhone, from the 2 megapixel single camera of the first generation of the iPhone in 2007 to the 12 megapixel dual camera of the XS series of the iPhone in 2018, to the upcoming three photos of the new iPhone, the "development history" of the iPhone camera is to some extent the same.Mobile phone"Popular History" of Photography.

On 9 January 2007,AppleCEO Steve Jobs officially released the first generation of iPhone, although the revolutionary multi-touch and more friendly user interface brought about a different smartphone experience, but in terms of hardware, the initial iPhone did not have an advantage in the mobile phone market at that time, such as not supporting 3G networks, not having built-in GPS, prices too high, and cameras with only 2 million pixels, not even supporting recording video. But its emergence laid the foundation for the rapid progress of iPhone later. The next year's launch of iPhone 3 G was the beginning of iPhone's popularity around the world. With support for faster 3G networks and Apple's App Store spurring many third-party developers to develop more apps, the iPhone 3G set a global sales record of 10 million units in just five months, although it was still equipped with a single camera the same size as the original iPhone.

Maintaining a year-by-year routine, the camera configuration of Apple's iPhone 3GS, launched in 2009, has finally been upgraded, most notably from a change in pixel size to 3.2 million from the previous 2 million. In addition, the iPhone 3GS is the first iPhone with flash lights and video recording support. Later, the upgrade plan of the iPhone camera basically focused on two aspects of "taking photos" and "video". Among them, the 2011 4S of the iPhone has to be mentioned.

After 3.2 million pixels of the iPhone 3GS and 5 million pixels of the iPhone 4, the camera of the iPhone 4S has been upgraded again, with an 8-megapixel camera and a larger aperture reaching f/2.4. This time, however, the focus is not on the numerical changes in pixels and apertures, but on Apple's adjustments to sensors and ISPs. Unlike the OmniVision sensors used in the previous iPhone 3GS and iPhone 4, the iPhone 4S carries a customized Sony Back-up Sensor, and the ISP (Image Signal Processor) has turned to Apple's independent research and development, which has greatly promoted the rapid development of the imaging quality of the iPhone, because of the independent research and development. With the help of ISP algorithm, the iPhone can better handle the white balance, exposure, saturation, noise and other elements of photos. It also started with the 4S of the iPhone, and Apple began to have its own fixed image tuning style.

Until the iPhone 6S, Apple had not focused on the pixel number upgrade, so in the iPhone 5, 5S, 5C and 6 series, we saw the familiar 8 megapixel camera, but in other peripheral functions, these generations of iPhones have done it. Some patches. For example, in order to reduce the risk of lens rubbing, the iPhone 5 uses sapphire lenses; in order to improve the effect of flash, the iPhone 5S introduces a dual flash called "Ture Tone", which can calculate the color temperature of the environment with the cooperation of software algorithms, and automatically adjust the intensity and intensity of the flash. Colors help users take more natural pictures when they turn on the flash; the new image signal processor with "Focus Pixels" technology is used in the iPhone 6 series, which relies on phase focusing technology to bring faster automatic focusing speed than traditional contrast focusing technology, and more importantly, the iPhone 6 Plus. It's also the first iPhone with OIS (optical shake-proof) features.

The emergence of optical anti-shaking is of great significance, because on the mobile phone with limited size of image sensor, the hardware defect of the "bottom" is not big enough makes the pixel quality of the mobile phone drop linearly in the dark environment. One of the solutions is to extend the shutter to increase the amount of light input, but this will magnify the impact of hand shaking, resulting in the picture model. Paste. The new optical anti-jitter function on the iPhone 6 Plus is to coordinate CPU, gyroscope and motion coprocessor to measure dynamic data and move the lens precisely to remedy the effect of hand jitter under weak light conditions.

I remember buying an iPhone 6 Plus when I was in college. It wasn't until last year that the current XS was eliminated because of battery aging. Compared with the flagship phones of the same period, the parameters of the 6 Plus camera of the iPhone were not bright. Especially at that time, the flagship phones had begun to use 20 million pixels of sensors and dual camera system to make selling points. But recall, the 6 Plus of the iPhone should be the most handy phone I used: take pictures, no silk. With no delay, I can always capture the moment I want to stay, plus my special interest in photography and the possibility of University leisure, I think my best photographs are from this 6 Plus iPhone.

With the boundaries of the iPhone 6 series, Apple has officially stepped into the era of "tens of millions of pixels" since the launch of the iPhone 6S Series in 2015, and used it now.

The change from 8 megapixels to 12 megapixels is obvious. First of all, Apple added the 6S series of the iPhone for the first time.4KVideo recording function, although the frame number is only 30 Fps, but this is the beginning of the "4K road" of the iPhone, this function has become the standard of future generations of the iPhone. In addition, the higher number of pixels also makes the image sharpness straight up, you can more freely cut the photo, and different concerns about the number of pixels is not enough to lead to blurred picture quality.

In 2016, Apple launched the iPhone 7 and iPhone 7 Plus, with a wide-angle long-focal dual lens system, the iPhone 7 Plus was Apple's first dual-shot iPhone, which not only allowed the iPhone 7 Plus to capture farther scenes with twice optical zoom and up to 10 times digital zoom, but also, in conjunction with wide-angle lenses, simulated the external focal virtual effect taken by SLR cameras, although at that time, it was able to capture farther scenes with double optical zoom and up to 10 times digital zoom, and more importantly, it was able to achieve "scattered scene simulation" with wide-angle lenses to simulate the external focal virtual effect taken by SLR cameras, although at that time, the long focal lens could not only capture farther scenes with double optical zoom and up to 10 times digital zoom.LGandHUAWEIA high-end model with dual cameras has been launched, but the iPhone 7 Plus is the first mobile phone to combine camera systems with digital computing capabilities, which also means that the iPhone has entered a new era of "digital photography".

The following iPhone 8 series, iPhone X, iPhone XS series, iPhone XR believe that everyone should not forget, the biggest highlight of the iPhone 8 series is the addition of 4K 60 frames of video recording and upgraded versions of "portrait mode" and "portrait light effect," while the iPhone XS series has made a small upgrade to the "old" CMOS, the size of the sensor from iPhone X has increased from iPhone X's 32.8mm to 40.6mm , and the iPhone 8 series has added 4K 60 frames of video recording and upgraded versions of "portrait mode" and "portrait light effect," while the iPhone XS series has slightly upgraded the "old" CMOS, and the sensor size from Sony X has increased from 40.6mm X. The unit pixel has also increased from 1.22 μ m to 1.4 μ m, and the density of focal pixel points is also higher, but the intensity of the upgrade is still not much higher than that of the flagship phones of the same era. In the aspect of software, the addition of smart HDR brings a better experience for HDR photography. From the point of view of the mobile phone, the effect of HDR processing has been displayed on the mobile phone in real time, and the "take-as-you-go" has been realized.

After more than a decade of development, the iPhone has become the pocket camera of many people. Under the influence of social networking and new media, it has gradually eroded the market of digital cameras and some low-end SLR cameras. According to CIPA statistics, in the year of the birth of the iPhone 4 in 2010, 122 million digital cameras were sold worldwide. But that figure has shrunk to 35 million in five years. On the contrary, the sales of the iPhone have been increasing. Cook announced in 2016 that the total sales of the iPhone had reached 1 billion, which is enough to prove the popularity of the iPhone.

As for this year's new iPhone, combined with outside rumors, its three camera systems may have more bright spots:

1. The new three-shot system may be "wide-angle lens long focal lens ultra-wide-angle lens";

2. "Intelligent Photo Frame" function: When other lenses are working, the ultra-wide-angle lens will record the picture at the same time, and the extra information will help users to cut and correct.

3. Enhanced LivePhoto, extended to 6 seconds;

42.12 million pixels sensor may be upgraded;

5. Video recording capability is improved. With the cooperation of A13 processor, the new iPhone may have the ability to shoot portrait mode video.
