What's the use of Apple's dual lens?

Question 1: What is the charm of the dual lens of Apple 7 plus? IPhone7 Plus uses dual cameras, which is more than iPhone 712 megapixel telephoto camera. The IPhone7 is only equipped with a12 megapixel wide-angle camera. In actual use, iPhone 7 Plus will have a better effect in low light environment, and at the same time, it can preview the depth of field in real time, thus having a good 3D effect. Built-in zoom function can realize 2x optical zoom and10x digital zoom.

The specific parameters are F 1.8 aperture, and the pixels reach12 million (7 million pixels in front), which supports optical image stabilization. At the same time, four True Tone flash lamps are added, which can sense ambient light when shooting photos and videos, and the brightness can be increased by 50%. At the same time, based on the brand-new ISP image processor, the computing performance can reach the level of "supercomputer".

Question 2: What is the use of the dual-lens configuration of Apple's mobile phone 7Plus? Why use a double lens?

1) enhances the focal length variation range of the lens. Because the mobile phone is too thin to use the zoom lens of the traditional camera, we can only use the method of multi-lens replacement, that is, the zoom lens of the mobile phone is expensive and the effect is not good. You still remember the days when cameras used fixed-focus lenses, and you needed to take several lenses to change when you went out to shoot. Now Apple is also doing this, helping you to bring an extra lens, telephoto lens, wide-angle zoom lens and automatic switching. If you have seen the lens of the old movie camera is three devices installed on a turntable and switched manually, today, iPhone7Plus achieves the same effect by using digital switching lens. Apple's iPhone6 lens can also zoom, but it can only zoom digitally, which is at the expense of losing pixels. Now zoom with a lens without losing the number of images.

2) Through the dual-lens configuration, we have the hardware to take 3D photos digitally. In the future, with the help of LineX's 3D depth mapping software technology, we can develop more 3D shooting applications, such as *** 3D photos, 3D scanning, 3D printing and so on. If there is no dual lens, you can't take naked-eye 3D photos, and people can only see the 3D effect with their eyes, so the shooting tool also needs dual lenses.

Question: What's the use of dual cameras on iPhone 7 Plus? The configuration of dual cameras is an assumed photography mode. Computational photography uses the built-in algorithm to analyze the information collected by two cameras to make up for the deficiency of a single camera. The existing automatic panoramic mosaic technology adopts the idea similar to computational photography, and the HDR high dynamic range photography technology that takes multiple photos and then merges them into one photo is also similar. People's way to improve the defect of single camera is simple and rude: just add more cameras. So in essence, dual cameras are just the first step in this rude solution.

Apple's dual camera configuration is not an eye-catching innovation, but they did a good job. The whole dual-camera system doesn't have too many calculation parts, only the background blur operation should be handed over to the software. At present, there is no corresponding software for the iOS system, but Apple will soon launch a corresponding system upgrade. IPhone 7 Plus is equipped with12 megapixel lens, 28 mm and f 1.8,12 megapixel lens, but 56 mm and f2.8

Apple compared the 56 mm lens in the iPhone 7 Plus to a "telephoto lens". But in fact, it is far from the telephoto, and the magnification is twice that of the 28 mm lens. This 56 mm lens can help you avoid the common photo distortion problems when taking portraits and other photos.

Apple's attention to the iPhone 7 Plus is a bit vague. The configuration list does not say "2x optical zoom", but "2x optical zoom". This small difference may not be noticed by many people. Technically, this system can achieve double zoom, because you have a 28 mm lens and a 56 mm lens, which means that two different lenses can zoom. Zooming, as the name implies, means that the focus moves from one point to another, so for Apple's "2x" statement, we can only understand that when the 28 mm lens zooms farthest, the 56 mm lens can take over the zoom task, which is like doubling the overall zoom capability.

If the second lens is 70 mm instead of 56 mm, then this is actually no longer an optical zoom. This situation should be called bifocal. Through the corresponding algorithm, the multi-camera system can focus between the focal lengths of two lenses. Apple just switched from the first lens to the second lens, and then called it "2x zoom".

JPEG photos you take with iPhone will be automatically compressed and processed. This kind of lossy compression will reduce the number of colors in the photo and the fidelity of bright and dark areas. This is easy to aggravate the trace of the photo being p when editing the picture later.

Raw images directly store the data received from the lens, so you won't let the traces of manual modification become more and more obvious when editing. The reality is that even if you can edit Raw pictures, the range of data you collect from such a small shot is limited, so adjust the exposure and noise anyway. It's true that you can manipulate all the data collected by the lens, but the problem is that the lens is really too big, and it doesn't collect many colors by itself.

Question 4: What is the function of the dual camera of Apple 7plus? Compared with the iPhone6s series, the biggest change of iPhone7 and iPhone7 Plus is probably on the back of the fuselage. In addition to the most obvious "crown antenna", the camera of iPhone7/7 Plus has also changed significantly: the camera of iPhone7 is more prominent, while the camera of iPhone7 Plus simply adopts dual cameras.

The convex camera will undoubtedly destroy the beauty of the fuselage. Why does iPhone7/7 Plus adopt such a design? Mainly because of the rapid development of Samsung S6/S7 series in the field of photography in the past two years, iPhone is no longer the benchmark in the field of photography. The application of large aperture, large sensor and optical image stabilization makes Samsung S7 the best mobile phone for taking photos at present. The biggest feature of this phone and the subsequent S7 Edge and Note7 is that there is a huge camera behind it.

Although the performance of smart phones is constantly improving, the volume of electronic components such as CPU and memory is constantly shrinking. But only one component has become bigger, and that is the camera of the mobile phone. Because no matter how mobile phone photography technology develops, it must follow the most basic optical principle, that is, the larger the lens volume, the more light it enters, and the better the imaging effect. If you want to take clearer photos, it is inevitable to make the camera bigger.

A larger camera can use a larger aperture and have a larger CMOS sensor area, which are the two most important parameters to determine the photo effect. On professional SLR cameras, we can make the lens very big and long, but not on smart phones. Apple's iPhone has always taken a thin and light route, and each generation of iPhone will strive to be lighter and thinner, and it is impossible to put down a larger camera component. Although Apple has a camera technical team of 800 people and a nearly perfect camera software algorithm. However, the field of photography is "crushing the bottom people". No matter how the camera of Apple iPhone is optimized in software, the innate gap in hardware can't be made up.

Through the photos of the real machine that have been exposed, we can see that the upcoming iPhone 7 has abandoned the 3.5mm audio interface for thinness, but the lens has become more prominent, because it is impossible for Apple to continue to reduce the thickness of the camera in order to ensure the photo effect of the iPhone 7. Otherwise, what do we compare with Samsung? In addition, it is said that the iPhone 7 has also added OIS optical image stabilization, which is one of the reasons why the iPhone 7 camera is more convex. The reason why iPhone 7 Plus uses two cameras is to increase the area of CMOS sensor in disguise, which is the same as Samsung Note 7 using a single larger camera.

To sum up, smart phones must make a fuss about the camera size if they want to improve their camera level. A big camera may not take a good picture, but a good mobile phone camera will definitely not be small. Therefore, the more convex camera of iPhone7 and the dual camera of iPhone7 Plus are necessary.

Question 5: What is the use of Apple iphone 7 dual cameras? It's just a rumor, not necessarily true. If you have a dual camera, you can take 3D videos and photos.

Question 6: What's the function of dual cameras of iphone7 plus? The camera of the iPhone 7 will usher in even greater changes. Optical anti-shake, triple exposure time, F/ 1.8 aperture, can bring 50% more light. Faster sensors reduce the time of taking pictures by 60% and improve the efficiency by 30%.

An optical module consisting of 6 pieces of glass and a True Tone flash consisting of 4 LEDs can provide 50% more light. It is worth noting that this generation of image processors, completely designed by Apple, has got rid of the limitations of suppliers.

Next is the main event. The camera module composed of dual cameras and two main cameras of iPhone 7 Plus is 654.38+0.2 million pixels. The two main cameras on Plus are12 million pixels, one for wide-angle shooting and the other for telephoto shooting.

Although dual cameras are not the first time in the mobile phone industry, Apple guarantees that their scheme can give the depth of field effect of shooting with iPhone 7 Plus. Apple proudly claims that this is the best camera and better photos that can be made on a smartphone. IPhone 7 Plus supports 2x optical zoom and10x digital zoom.

SLR can achieve the effect of low depth of field with blurred background. Using the brand-new portrait mode, you can create the same depth of field effect as the background blur. Taking advantage of the depth-of-field effect of the iPhone 7 Plus dual camera, Apple proudly claims to be the best camera that can be made on a smartphone.

Question: What's the use of dual cameras on iphone7plus? Apple's iPhone 7 series came out, with quad-core processor and stereo speaker, 3.5mm headphone jack removed, splash-proof, waterproof and dustproof functions, stunning bright black, brand-new display screen, and brighter and richer colors. The most eye-catching thing for users should be the dual cameras.

The dual cameras brought by iPhone 7 Plus use wide-angle and telephoto lenses, and the left and right cameras use different FOV (viewing angle), so the viewing angles of the two cameras are different. Use a wide-angle lens for close-up shooting and a telephoto lens for long-distance shooting. So as to realize the optical zoom function.

The wide-angle main camera in the dual camera of iPhone 7 Plus is exactly the same as that on iPhone 7, with1200,000 pixels, F 1.8 aperture and 28 mm equivalent focal length. Although the telephoto sub-camera is also12 million pixels, the aperture is F2.8 and the equivalent focal length is 56 mm

The cutting coefficient of 1/3 inch sensor is 7.2 1. If the sensor of the main camera of iPhone 7 Plus is so big, the equivalent focal length should be 3.99× 7.2 1 = 28.768 mm, which is very close to the 28 mm announced by Apple.

The sensor of the sub-camera should be 1/3.6 inches, and the cutting factor is 8.6, which is 6.6× 8.6 = 56.8 mm, which is also very close to Apple's specifications.

In contrast, the camera sensor of iPhone 6S/6S Plus is also 1/3 inches, and the equivalent focal length is 4.15× 7.21= 29.92 mm. ..

Generally speaking, with the same effective pixels, the smaller the sensor size, the more noise there will be, but Apple has been very experienced in noise reduction. For example, when jumping from 8 million pixels to 6.5438+0.2 million pixels, the sensor size has not changed, so Apple added a strong noise reduction algorithm.

Although the existence of iPhone 7Plus brings more imagination to consumers, it is not so perfect in practical application, which comes from the combination of wide angle and telephoto. The dual camera of Apple 7 is only the conversion between wide-angle and telephoto cameras. Between 1x and 2x, the so-called optical zoom is simulated by digital zoom. It's just that Apple makes this change very natural through its own ISP and powerful algorithm.

Question 8: What does the dual lens of Apple 7 plus mean? There are two lenses on the back of the mobile phone, which are generally responsible for large-scale shooting (wide-angle lens) and one for long-distance shooting (telephoto lens). It is of little practical significance, because after all, it is a small area imaging, so make do with it.
