Apple Huawei millet in use: standard-cell phone dual camera into a high-end machine, dual cameras-IT information

After following the fingerprint identification phone standard, dual cameras have also become producers of the new "weathervane". Equipped with dual cameras mobile phones are changing up, even Apple also introduced a dual-lens design iPhone7 Plus. So, what is the reason that manufacturers for a dual-lens so popular?

As we all know, mobile is the product of highly integrated, cameras were hidden in them. As phones increasingly thin in thickness and the width of the camera to be thinned with the fuselage is more difficult. So much ridicule of the webcam phenomenon of convex is one to compromise on choices.

While the two cameras appear completely solves this problem. Of course, in addition to the reasons set out above, dual cameras have an advantage in the pictures also. Dual-lens can significantly increase the amount of the light camera to enhance photographic ability and picture brightness, can effectively reduce noise.

In 2016, the full-scale development of mobile phones from a single photo to dual trends in photography. Remember the "ten nuclear double stem head" red Pro? Now involved in dual camera cell phone is also increasing. So here's the thing, these dual camera mobile phone technology to have any different? You may wish to read.

Black and white + color double perturbation scheme

A case study of Chinese-made models, more commonly used on the market are the same pixel black and white + color dual-camera program. Two cameras, black and white is responsible for capturing the details of the camera profile color lens full-fill color. Black and white photography compared to a single camera resolution, night photograph details such as superior, representative works including 360 Mobile flagship and Huawei P9 and other products.

New launch of the glory glory V8 and glory 8 also adopted the same pixel black and white + color double-lens, two camera collaboration, combined laser/depth/triple contrast AF mode focus fast, precise light larger, compared to single-lens Imaging ability has improved tremendously.

In addition, launched jointly with the cool eco cool1 dual is also based on this programme. Double 13 million megapixel primary camera, a lens is responsible for capturing the details profile, a color lens full-crawl. To achieve synchronous focus, use black and white lenses are also available separately. More high definition, low noise and superior imaging and more.

Pair of different pixels camera technology

There is also a different pixel pair of camera technology, where high megapixel primary camera is responsible for imaging, the Deputy shot the full-time measurement data such as depth of field. Photos first, then focus can be realized and other functions, like HTC M8, ZTE AXON secret are using this technology.

In addition, millet's first dual camera cell phone red m Pro builds on this technology. Among them, 13 million megapixel main camera for the final image, secondary camera is used to capture images of 5 million pixel subject distance information, performance and more focused on the background blur, can easily produce results comparable to DSLR photos of depth of field.

Apple has always had a good performance in the photos, and new launch iPhone7 Plus is Apple's first dual camera-phone. Prior to that, Israel LinX has its own product in contrast to iPhone photograph 5S to highlight his dual camera "teeth", and successfully attracted the attention of Apple, rich also bagged apples.

IPhone7 Plus a 12 million-pixel wide angle + 12 million pixel camera Jiao Shuang, primary camera with F/1.8 large aperture, with 28 mm equivalent focal length. Telephoto F/2.8 the Deputy camera aperture, 56 mm equivalent focal length. Both cameras work together to achieve twice the optical zoom and up to 10 times digital zoom, and the new depth of field will shoot portraits of more outstanding, create a blurry background effect.

Concluding remarks:

As well as fingerprint identification, dual camera thanks to its outstanding imaging capabilities are or will become the standard. All told, "one wide and one narrow," "one black and one white," "a large and a small" three mainstream dual-intake programmes one by one by the manufacturer. But can play the real power of a dual camera, eventually falls on the optimization of camera.

苹果华为小米都在用：双摄像头成高端机标配 - 手机,双摄像头 - IT资讯

继指纹识别成为手机的标配之后，双摄像头也成为厂商们新的“风向标”。搭载双摄像头的手机也逐渐多了起来，甚至是苹果公司也推出了双镜头设计的iPhone7 Plus。那么，什么原因让厂商们对于双镜头如此趋之若鹜呢？

众所周知，手机是高度集成化的产物，摄像头也被隐匿于其中。随着手机在厚度上越来越轻薄，而摄像头的宽度要想与机身一同变薄则较为困难。因此，备受吐槽的摄像头凸起现象其实也是一种不得不妥协的选择。

而双摄像头的出现则彻底解决了这一难题。当然，除了上述原因之外，双摄像头在拍照方面也更具优势。双镜头可显著加大摄像头的进光量，提升感光能力和照片亮度，还可有效降低噪点。

2016年，手机大有从单摄全面发展至双摄的趋势。还记得“十核双茎头”的红米Pro吗？如今涉足双摄像头的手机也越来越多。那么问题来了，这些双摄手机在技术上有什么不同？大家不妨往下看。

黑白+彩色双摄方案

以中国国产机型为例，市面上较为常用的当属相同像素黑白+彩色双摄像头方案。两颗摄像头中，黑白镜头负责捕捉细节轮廓，彩色镜头则专职填充色彩。黑白双摄组合相比单一摄像头在解析力、夜晚拍照的细节等方面更胜一筹，代表作品包括360手机旗舰版和华为P9等产品。

荣耀新晋推出的荣耀V8和荣耀8也采用了同像素黑白+彩色平行双镜头，两颗摄像头协同合作，结合激光/景深/反差三重对焦模式，对焦快而精准，进光量更大，成像能力上相比单镜头也有了大幅提升。

此外，乐视与酷派联合推出的生态手机cool1 dual也基于这一方案。双1300万像素主摄像头中，一颗镜头负责捕捉细节轮廓，一颗镜头则专职抓取色彩。既能够实现同步对焦，也可单独使用黑白镜头。清晰度更高，噪点更低，成像方面也更出众。

不同像素的主副双摄像头技术

还有一种便是不同像素的主副双摄像头技术，其中，高像素主镜头负责成像，副镜头则专职测量景深等数据。可实现先拍照后对焦等功能，像HTC M8、中兴AXON天机等均采用了此技术。

此外，小米首款双镜头手机红米Pro也借鉴了这一技术。其中，1300万像素主摄像头用于最终成像，500万像素副摄像头则用于捕捉画面主体距离信息，并更关注于背景虚化的表现，可轻松拍出类似于单反效果的景深照片。

苹果在拍照上一直有着不错的表现，而新晋推出的iPhone7 Plus更是苹果的首款双摄像头手机。此前，以色列的LinX曾拿自家产品与iPhone 5S进行拍照对比，以突显自家双摄像头的“威力”，并成功吸引了苹果的注意，财大气粗的苹果也将其收入囊中。

iPhone7 Plus搭载1200万像素广角+1200万像素长焦双摄像头，主摄像头采用F/1.8大光圈，拥有28毫米等效焦距。长焦副摄像头的光圈为F/2.8，等效焦距则为56毫米。两颗摄像头协同合作，可实现2倍光学变焦和最高10倍数码变焦，而全新的景深效果也会让拍出的肖像更为出众，营造出模糊的背景效果。

结束语：

如同指纹识别一样，双摄像头凭借其优异的成像能力也或将成为手机的标配。总结来看，“一广一窄”、“一黑一白”、“一大一小”三种主流的双摄方案也被厂商们所一一采用。但能否发挥出双摄像头的真正实力，最终还是要落在相机的优化上。
