How the dual camera technology is implemented in smartphones from different manufacturers, and how this affects the original result, that is, the photograph.

Recently, dual camera has become one of the main trends in the smartphone market, and more and more manufacturers are adopting the new technology in their products. Although it first appeared in the HTC One M8, introduced in April 2014, it only became really fashionable this year after the release of the Chinese flagship Huawei P9. We will tell you which are the best gadgets on the market equipped with a trending module.

Attention! Prices and list are current at the end of September 2016.

The device is equipped with two 12-megapixel sensors (BSI CMOS Sony IMX286 matrix): one takes color pictures, the other - monochrome. By superimposing them, you achieve higher detail in the photo, greater dynamic range, the ability to focus after the photo is taken, as well as improved quality and less noise when shooting in low light. It is noteworthy that this camera is certified by German.

Each pixel is 1.25 µm in size. The module is equipped with an f / 2.2 aperture, laser autofocus and dual LED flash. Aperture can be adjusted from f / 0.95 to f / 16, there is support for shooting in RAW format.

Huawei Honor 8

The smartphone inherited a dual camera from the Huawei P9 model: 12-megapixel color and monochrome sensors, f / 2.2 aperture (adjustable from f / 0.95 to f / 16 for optimal depth of field), pixel size 1.25 microns, laser autofocus and dual LED flash. However, the optics did not receive the certification of the Leica brand, the interesting film mode and the ability to take RAW images - most likely this influenced the decrease in the price tag. Other characteristics of the device.

Price: about $ 525.

LG G5 / G5 SE

LG is slightly ahead of the Chinese brand by adopting a dual camera in. However, due to the modular design, implying the purchase of additional ones at a rather high price, the device has not gained much popularity among users.

In the South Korean smartphone, the dual camera has received a different implementation: it consists of a 16-megapixel conventional sensor and an 8-megapixel wide-angle sensor with a viewing angle of 135 degrees. In addition to LED flash and laser autofocus, the f / 1.8 module is equipped with optical image stabilization, which plays an important role in the quality of photography. It is also possible to manually adjust parameters, including white balance, exposure, shutter speed, etc.

Price: from $ 490 for the simplified version (G5 SE), from $ 624 for the standard version.

This model uses a similar camera to the previous flagship LG G5. It also consists of a 16-megapixel f / 1.8 conventional sensor and an 8-megapixel f / 2.4 wide-angle sensor with a 135-degree field of view. Provides a system of optical image stabilization (on a 16-megapixel module), dual LED flash and advanced hybrid autofocus, consisting of phase, laser and contrast focusing.

There is also the ability to manually adjust all camera parameters, including white balance and exposure. Other details about the smartphone.

Price: about $ 750.

This is with a dual camera in the range of the Chinese company Xiaomi. On the back of the device is a dual module with a 13-megapixel Sony IMX258 sensor and a 5-megapixel Samsung sensor, between which there is a dual LED flash. The aperture is f / 2.0, but it can be adjusted from f / 0.95 to f / 5.6 to adjust the depth of field.

One sensor focuses on distant objects, and the other - on objects located nearby. This technology allows you to take quick photos, and adjust the focus later.

In this article, it is impossible not to mention the flagship, which does not belong to Android devices, but received a really impressive dual camera. It consists of two 12MP sensors, one equipped with an f / 1.8 wide-angle lens and the other with an f / 2.8 telephoto lens. This combination allows not only to improve the quality of photos, but also to achieve 2x optical zoom in combination with 10x digital zoom.

The camera is equipped with a 6-layer lens, optical image stabilization, fast autofocus with Focus Pixel technology and 4-LED True Tone Quad-LED flash (with two warm and two cold LEDs). Along with the software update, the smartphone will have a portrait mode that will bring with it the ability to create bokeh effect, just like on a DSLR. The company has already released the beta version of iOS 10.1.

Outcome

Even now, in many situations, a smartphone can practically replace a full-fledged camera. The advent of the dual camera further expands the photography capabilities of mobile devices.

Many major manufacturers have already presented their take on the new technology, and it would be interesting to see how it is implemented by the South Korean brand Samsung, probably in the next flagship.

A dual camera is a 2016 trend in smartphone construction, although the first attempts to place two photo modules behind a mobile device were made much earlier. Considering that the iPhone 7 Plus is equipped with a dual camera, and others (especially the Chinese) like to imitate Apple - the tradition of equipping their offspring with a pair of cameras continues in 2017. Why does a smartphone need a dual camera - let's try to figure it out.

One of the ways to use the dual camera is to take stereo photos for viewing on a 3D monitor. To do this, the smartphone is equipped with a pair of modules located at a short distance from each other. Each lens has a slightly different field of view, similar to how the left eye sees everything from a slightly different angle than the right. Due to the separation of images from cameras (usually anaglyph, with the help of red and blue filters) - when using special glasses, such photos seem three-dimensional, three-dimensional.

The first smartphones with a dual 3D camera were the LG Optimus 3D Max and HTC Evo 3D. However, the technology is not without its drawbacks, primarily due to the fact that the distance between the lenses is different from the distance between the eyes. Smartphones with stereo cameras have not become popular.

Expansion of the field of view

The second way to use the dual module in a smartphone is to expand the field of view of the lens. Conventional (universal) optics are designed for shooting both macro and landscapes. Because of this, its viewing angle is rather limited: in order to get everything into focus, you will have to use strongly curved lenses with a fish-eye effect, or make non-standard wide-format photosensors (for example, with 2: 1 proportions). An additional module, equipped with the most suitable components for landscape photography and panoramas, saves the day.

An example of a smartphone that uses a second camera to capture panoramas and landscapes is the LG G5. For such gadgets, the main matrix is ​​universal, and has viewing angles of 70-90 degrees. The second is more highly specialized, with a field of view extended to 100-120 and more degrees. This allows you to make panoramas in an instant, without the use of gluing and moving the smartphone, which inevitably leads to the appearance of graphic defects in the picture.

Optical approximation

One of the drawbacks of smartphone cameras is the lack of optical zoom. When approaching the subject, the system simply takes a piece of the image and “stretches” it to the desired size, but this does not improve the detail. They tried to integrate a full-fledged zoom mechanism back in 2005-2006 (for example, in the Nokia N93). However, it is complex, large (to be sure, it is enough to look at the “soap dishes” with a telescopic lens) and expensive, therefore it does not fit. But if you just put two identical cameras, one of which has standard optics, and the second telescopic, then switching between the modules - you can zoom in on the subject.

The dual module used for optical zoom is on the Apple iPhone 7 Plus. Both matrices in it are the same, but one is equipped with high-aperture optics with standard parameters, and the second with a limited viewing angle, but with a long-range view.

Improving the clarity, detail and contrast of photos

A digital camera best of all captures in the picture the object on which the focus was made. Side details will be rendered less efficiently. Considering that two cameras and light will catch more, and can focus on different points independently, they will be able to provide a clearer transmission of details. Two photos, combined by HDR principle, combine the advantages of both cameras. For example, if one focuses on a bright summer sky, and the other focuses on objects in the shadows, then the sky will be just as bright in the frame, and the shadowed objects will not appear in the dark.

The use of a dual module with cameras, one of which is color, and the other is monochrome (like Huawei), increases clarity and detail. The black and white sensor does not need a clear hue (it simply transmits it in one of the grayscale levels), so it “focuses” on contours rather than color. It is for this reason that night surveillance cameras are made monochrome. The color matrix is ​​engaged in fixing colors, the black and white matrix is ​​better for registering small details, and together they give both a bright and detailed picture.

Focus on the subject, bokeh effect

A feature of near-field lenses used in conjunction with professional cameras (mirrorless, DSLRs) is the natural “bokeh effect” - blurring the background, with extraordinary clarity of objects in focus. A universal lens (with which the matrix of an average smartphone is equipped) cannot do this in principle - the optical parameters are not the same. But if you make two modules, one of which will focus on the subject of shooting, and the second will fix what needs to be blurred - gluing frames from them will allow you to achieve the desired effect. This blur is achieved programmatically. The iPhone 7 Plus is considered the benchmark for bokeh shots. An example of a bokeh effect using the iPhone 7 Plus:

For the bokeh effect and detailing of the subject, the dual matrix is ​​also used in Xiaomi smartphones (Mi5S Plus, Redmi Pro). Not always very successful, but on average - the effect is slightly better than using purely software methods of blurring the background.

Other effects

There are other purposes for which a dual camera can be used in a smartphone, but they are not so common. For example, in Xiaomi with a dual matrix, you can take photos with interchangeable focus, but this feature is actually a derivative of the already mentioned sharpening function. You can also make two cameras with different fields of view, from the images of which a seamless wide-angle panorama will be glued, but this function is also not in demand yet. In principle, a double module can be used in many ways, everything is limited only by the imaginations of the developers. So in 2017, new applications can be expected.

After all, a separate article has been written on this topic. We will just say that the dual camera module became the main trend in 2017 and is still holding up even in 2019, despite the appearance of models with triple, quadruple and even fivefold cameras. Now even budget Chinese smartphones are starting to receive such a camera. At the same time, it is not always clear what role it plays. Therefore, it is extremely difficult to choose a decent device with a dual camera. Unless you have checked out our selection of the best models.
