Quite often it turns out that the know-how modern phones is a well forgotten past. This was the case with fingerprint sensors, and with the release of the iPhone 7 Plus, dual cameras may return.
Apple's smartphone is far from the first to have such a solution. The first phone with two cameras came out in 2007 - then the iPhone didn't even support apps and 3G. Engadget in its material all devices from the past that had two cameras.
Samsung SCH-B710
The first phone had two cameras in order to shoot 3D content. Samsung SCH-B710 was released in April 2007 and had a pair of 1.3 megapixel sensors. Its 2.2-inch screen with a resolution of 320x240 pixels used parallax to display three-dimensional content. Plus, you could watch local terrestrial television on the gadget.
LG Optimus 3D
The next dual-camera phone came out many years later - in 2011. It was the LG Optimus 3D, which was the first Android smartphone with a 3D camera. The latter had five megapixels per lens and recorded 720p video. The Optimus 3D screen also showed stereo content at 4.3 inches with a resolution of 480x800 pixels.
HTC EVO 3D
The EVO 3D gadget from 2011 was actually an improved version of the LG Optimus 3D. It had a 4.3-inch screen with 960x540 pixels, a powerful Snapdragon chipset. But the cameras were the same, along with 720p 3D video recording.
Sharp Aquos Phone SH-12C / SH-80F
The same 2011 Sharp Aquos Phone SH-12C was released (international marking SH-80F). It was an Android smartphone with 8 megapixel cameras. The display of the device was 4.2 inches with a resolution of 540x960 pixels.
Htc one M8
The next device came out in 2014 - it was HTC One M8, which received a new type of dual cameras with the marketing name Duo Camera. The main sensor had a 4-megapixel HTC UltraPixel matrix, and it was helped by a 2-megapixel sensor, thanks to which the device's autofocus worked faster. In addition, the M8 offered a set of post-shoot effects based on two cameras.
Huawei Honor 6 Plus
At the end of 2014, Huawei released a dual-camera phone. The Honor 6 Plus had two 8-megapixel sensors, which Huawei said together produced 13-megapixel images. In the Honor 6 Plus, in addition to improving the quality of images, two cameras also allowed faster autofocus and additional image processing effects.
HTC One M9 +
In 2015, HTC released the M9 +. In it, the dual Duo Camera no longer had an UltraPixel sensor, but used a 20-megapixel matrix from Toshiba. A little later, in the M9 + Supreme Camera Edition, the sensor was replaced with a 21-megapixel Sony sensor.
LG V10
In late 2015, LG released the flagship V10. He took a new approach: the cameras had different lenses. One was a standard 80 degree lens and the other was a 120 degree wide angle lens.
CAT S60

Released in February 2016, the CAT S60 gadget has two cameras and perfectly photographs both during the day and in complete darkness. This is because one of his cameras is a thermal imager. He does not need ordinary light - he “sees” the warmth of objects. True, you had to pay for this - the phone costs $ 599.
Lenovo Phab 2 Pro
The Lenovo Phab 2 Pro hasn't gone on sale yet. But it should be the first smartphone to have Google Tango 3D vision technology. It allows you to scan objects and get their virtual models, and also expands the possibilities of augmented reality.
Perhaps we forgot to mention some smartphones with two cameras. Write about them in the comments.
The dual camera is a trend in 2016 in smartphone construction, although the first attempts to position it behind mobile device two photo modules have been undertaken 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 a smartphone has 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 on short distance apart. 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, using 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 widen 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 \u200b\u200buniversal, and has viewing angles of 70-90 degrees. The second is more highly specialized, with a field of view extended to 100-120 degrees or more. This allows you to make panoramas in an instant, without using 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 the subject approaches, the system simply takes a piece of the image and “stretches” it to the desired size, but the detail does not improve from this. They tried to integrate a full-fledged zoom mechanism back in 2005-2006 (for example, in 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 has 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 the object on which focus was made in the picture. 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 the 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 shadow, 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 rendering of the hue (it simply transmits it in one of the grayscale levels), so that it “focuses” on the contours rather than the color. It is for this reason that night surveillance cameras are made monochrome. The color matrix is \u200b\u200bengaged in fixing colors, black and white - better registers 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 the 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 bokeh effect and detailing of the subject of shooting, the double matrix is \u200b\u200bused in smartphones Xiaomi (Mi5S Plus, Redmi Pro). Not always very successful, but on average - the effect is slightly better than when used purely program methods blur the background environment.
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.
The first dual camera in phones appeared back in 2007 with the release of Samsung B710, then the resolution of each module was 1.3 MP. Android smartphones first got a dual photomodule in 2011, these were the HTC Evo 3D and LG Optimus 3D models. In both cases, the duo of cameras was used to enable shooting 3D video that could be viewed on the screen of the gadget.
The dual photo module was "reinvented" in 2014 with the release of HTC One M8, and after iPhone presentations 7 Plus, it has become one of the main trends in the smartphone market. We have compiled for you a selection of smartphones with dual cameras in different price categories - from branded flagships to budget Chinese devices.
The iPhone 7 Plus uses two optical image stabilization modules, 12 MP each. The first is equipped with a 56mm f / 2.8 telephoto lens, the second with a 28mm f / 1.8 wide-angle lens.
This combination performs several functions at once, the main of which is imitation of bokeh (software blur background), which the iPhone does better than any other competitor. In low light, the smartphone always uses a lighter wide-angle module, in addition, it allows you to shoot macro from a minimum distance, while the tele-lens provides the possibility of double optical zoom, without loss of quality.
the iPhone 7 Plus is one of the most powerful smartphones on the market. It runs on the A10 Fusion processor (2.23 GHz), has 3 GB of RAM and 32, 128 or 256 GB of internal memory. The display is represented by an impeccable 5.5 '' IPS matrix with FHD resolution, and a 2900 mAh battery is responsible for autonomous operation. Prices for the younger version of the apple start at 65 thousand rubles
Huawei P9
The dual 12 MP photo module in Huawei P9 works according to a different principle: one matrix here is color, the second is monochrome. When shooting, the cameras are triggered simultaneously, after which the frames are programmatically combined into one. Black and white matrix in in this case provides better detail and an increase in the amount of captured light, which improves the quality of images in low light.
The photos on the Huawei P9 are really cool, the smartphone may well compete with the market leaders in the face of the iPhone 7 Plus and Galaxy S7. The P9 does not graze in terms of technical characteristics, the gadget with a 5.2 '' IPS FHD screen is equipped with a Kirin 955 processor (2.5 GHz), 32/3 or 64/4 GB of memory with a slot for Micro SD and a 3000 mAh battery. Price - from 35 thousand rubles.
Honor 8 is a smart phone with a chic design that inherits the dual camera from the P9. The photo module this time without the Leica nameplate, which is why the gadget costs an order of magnitude cheaper, about 25 thousand. However, in all other respects, the cameras are extremely similar - 12 MP resolution, dual flash, hybrid laser autofocus. Smartphone takes pictures excellent quality, detailed and with the widest dynamic range.
Honor 8 was awarded the title of one of the most beautiful devices of 2016, in addition, it has very good specifications... The device is powered by a Kirin 950 processor (2.3 GHz), has 4 GB of RAM and 32/64 internal memory expandable. 5.2-inch IPS FHD display, 3000 mAh battery, 8 MP front camera.
The ceramic case of Honor 8, which provides a wow effect when looking at the smartphone, is very delicate and does not resist scratches that appear on it after several weeks of use without a case. Also, among the shortcomings, we note the mediocre video recording quality, the possibility of shooting in 4K is not provided at all.
Lg g5
The previous model of the LG G4 smartphone was considered one of the best camera phones in its class and remains so at the beginning of 2017, but the updated version of the top-end device also deserves attention. The Korean company has once again confirmed the title of the main experimenters in the market and was the first among the A-brands to equip its flagship with a dual camera. In addition, the G5 is modular and its functionality can be expanded with additional accessories.
LG G5 is equipped with 2K IPS 5,3 "screen, Snapdragon 820 processor (there is also a completely identical SE version with 651 dragon), 32/4 GB of memory and 2800 mAh battery. The resolution of the cameras is 16 MP (the main module with an optical stub and aperture f / 1.8) and 8 MP (wide-angle), there is also a laser autofocus that provides instant focusing in any conditions.
The difference in capturing a regular and a wide-angle lens Among the modules for the G5 are available: a camera control unit (with a shooting button, focus wheel and an additional battery), an external DAC and a replaceable battery. The advantage of the device is also its price, now the smartphone has become much cheaper and costs about 30 thousand. The main disadvantage is the short time autonomous work, however the G5 working day will survive.
Smartphones with dual front camera on the market you can count on fingers, and Vivo X9 is the best of them in terms of the set of characteristics. This gadget will definitely delight lovers of selfies, it is equipped with 20 MP and 8 MP front modules, and can simulate bokeh no worse than the iPhone 7 Plus. The main camera is also good, with a resolution of 16MP.
Vivo X9 has a 5.5 '' Super AMOLED FHD screen, 4 GB of RAM and 64/128 ROM, a 3050 mAh battery and a dedicated DAC AKM4367, thanks to which the smartphone is head and shoulders above most competitors in terms of sound quality in headphones. Also, the Plus version will soon go on sale, which differs in a screen enlarged to 5.88 '', a Snapdragon 653 processor, a 4000 mAh battery and 6 GB of RAM. Smartphones start at $ 430.
Redmi Pro is a top-end budget phone from Xiaomi, in which a dual camera is used for soft blurring of the background. The main module has a resolution of 13 MP, the auxiliary one, designed to determine the image depth - 5 MP, the aperture of both cameras is f / 2.0. A distinctive feature of Redmi Pro from similar smartphones is the ability to imitate bokeh not only in photos, but also when shooting videos.
This smartphone can hardly be called a gaming one, since it works on the basis of the Helio X20 processor (or X25, depending on the version). For the rest of the characteristics, this is a perfectly balanced solution - AMOLED FHD 5.5 '' screen, 3/4 GB of RAM and 32, 65 or 128 GB of internal memory, 4050 mAh battery, a slot for a flash drive.
However high price on this model (16-22 thousand, depending on the version) puts it on a par with the company's flagship - Xiaomi Mi5, which in general looks like a more attractive solution and, despite the absence of a second photomodule, shoots an order of magnitude better.
Le Eco Cool1 can be considered as a great alternative to Redmi Pro. It is relatively inexpensive and productive smartphone with a dual camera, a Snapdragon 652 processor, 3/32 GB of memory, an IPS screen with an FHD 5.5 '' resolution, and a 4060 mAh battery.
Cool1 uses a dual 13MP module with f 2.0 aperture, phase detection autofocus and dual-tone flash. The smartphone has extremely high quality pictures, including in low light, and can record videos in 4K format.
Among the drawbacks of Cool1 is its specific design with large black frames around the screen. In all other respects, this is an excellent workhorse that can be bought for 13 thousand rubles, while Le Eco is officially presented in Russia and you will receive a full warranty from the manufacturer.
Doogee Shoot and Oukitel U20
Closing our rating are two inexpensive smartphones from second-tier Chinese manufacturers, which are very similar to each other. Both cost less than $ 100 and are typical budget employees in terms of performance. The differences lie in the battery capacity, the U20 has 200 mAh more, and the cameras - the Doogee uses two 13 MP and 8 MP sensors, the last of which is wide-angle, while the Oukitel has 16 MP IMX135 sensors.
Both smartphones are equipped with MediaTek MT6737T processors (1.5 GHz), FHD 5.5 '' IPS screens from SHARP, and 16/2 GB of memory expandable with flash cards. This is a good option if you are on a tight budget but want a decent smartphone capable of imitating a DSLR.
After all, a separate article has been written on this topic. We will only say that the dual camera module became the main trend in 2017 and holds true 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. However, 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.

Conclusion
You should have noticed that we were not mentioned inexpensive smartphones, Besides ASUS Zenfone Max Pro (M2). And everything from the fact that we have told only about those devices that are able to surprise with their dual camera. If your budget is up to 15,000 rubles, then you are severely limited. Yes, inexpensive devices in recent times also get a double camera. But most often it includes modules with the same optics. You can only rely on beautiful bokeh, but a cheap smartphone does not always cope with its creation, although new models do it better and better.
Are you already using a dual camera device? Or do you think that such a miracle is unnecessary for you? We are waiting for your opinion in the comments.

The world of technology does not stand still and if in 2016 a 20 megapixel camera was considered something pretentious, then in 2017 many phones are already equipped with dual cameras. Not all users understand why a modern smartphone needs a dual camera, but this does not stop manufacturers from releasing such devices. In our ranking, the top 10 Chinese phones with a dual camera module that you can buy now.
1 Huawei Mate 9
Huawei Mate 9 is flagship smartphone, which, in addition to the top-end filling, also promises the user an unusual experience of using photo and video capabilities. On its rear side, a dual camera module is vertically located, which includes a black and white 20 megapixel camera and a color 12 megapixel camera. This is done for the most accurate color reproduction and contrast level in the photo. In terms of additional technologies, the Mate 9 has optical stabilization OIS, dual LED flash, 2x hybrid zoom, Leica optics and 4K video recording.
The rest of the characteristics of the smartphone are also at their best: the flagship HiSilicon Kirin 960 processor, 4/64 GB of memory and OS Google android 7.0 Nougat. The estimated cost of the Mate 9 in China is $ 760.
2 Xiaomi Mi5S Plus
Mi5S Plus became the senior model in the line of Xiaomi flagships at the end of 2016 and the second phone from Mi to receive a dual main camera module. The design uses two identical sensors of 13 Mp each, only one shoots in b / w, and the second in color. As in the case of Huawei, this solution is aimed at increasing the color accuracy and contrast in the final image.
Mi5S Plus also supports HDR mode and fast PDAF phase detection autofocus. In addition, the flagship is equipped with Qualcomm's top-end Snapdragon 821 processor with a maximum frequency of 2.35 GHz per core and boasts a large 5.7-inch FHD display.
