Nowadays, mobile phone manufacturers are using more and more new technologies on their cameras, and the number of cameras has also increased. So what do the dual-camera, triple-camera, and quad-camera of the mobile phone camera mean and what role do they play?Dual-cameraThe so-called dual-camera mobile phone is a mobile phone equipped with a rear dual-camera. The simple understanding is that there are two cameras on the back of the phone, such as the iPhone 8 Plus. Different brands of mobile phones have different functions of the two rear cameras. We can take a look at the effect of dual cameras through the camera mode.Depth of Field CameraThe high-pixel main camera is responsible for shooting the overall picture; the low-pixel secondary camera is responsible for recording depth information, mainly for blurring the background and highlighting the subject. Such as HTC M8, Meizu Note6.Color + black white cameraThis kind of camera makes subtle differences in the structure of the rear camera and presents high-quality imaging effects after algorithm fusion. Mainly for clear imaging and suitable for shooting at night. Such as Nubia Z17mini, Huawei Honor 9.Fixed focus dual cameraAlso called wide-angle & telephoto dual-camera, as the name suggests, the two cameras are a wide-angle camera and a telephoto camera. Under different lighting conditions, the mobile phone can independently select the appropriate camera to shoot, mainly for easier zoom shooting. For example, mobile phones such as iPhone 7 Plus, Mi 6, and OnePlus 5.Triple-cameraWith the concept of dual-camera phones, triple-camera means that there are three cameras on the back of the phone. At present, there are many types of three-camera phones on the market. Let's take Huawei P20PRO as an example;The three cameras of Huawei P20pro are main camera color imaging, secondary camera black white imaging, telephoto camera zoom, and anti-shake. It does not rule out that other manufacturers use different camera technologies to rearrange and combine to obtain a new three-shot effect. For a long time, night photography has been a "forbidden zone" for mobile phone photography, and Huawei's three-camera solution stepped into the forbidden zone to improve the effect of night shooting. The secondary camera of Huawei P20Pro is a black white sensor and the color separation filter is canceled, so it will have a higher light input than the color camera, and the image details will be clearer. Two images are merged by software to get a clearer picture than a normal color camera. This kind of sharpness enhancement effect is especially obvious when shooting night scenes. The black and white secondary camera can also bring a more accurate zoom effect.Quad-cameraLet’s take the Samsung Galaxy A9 as an example. The four rear cameras are the main camera, the telephoto camera, the ultra-wide-angle camera, and the depth camera.The main camera is 24 million pixels with an F1.7 aperture. The main camera also provides a "low light" mode, which combines 4 pixels into one group. Although the photo resolution is lower (6 million pixels), the brightness and noise of the photo are controlled. Will be betterThe telephoto camera has 10 million pixels, F2.4 aperture, and can provide 2x optical zoom;The ultra-wide-angle camera provides a 120-degree wide-angle lens with 8 million pixels;The depth camera is 5 million pixels, F2.2 aperture, the sole purpose of the camera is to calculate the depth of field of the object, you can select the focus and depth of field after taking a picture.The replacement of mobile phones is getting faster and faster.
