At present, major mobile phone manufacturers have begun to use multi-camera designs, and with the upgrading of mobile phones, the number of cameras is increasing. Why does it need so many cameras to take a picture? What are the differences between seemingly identical cameras? In this blog, we’ll discuss each function of various kinds of cameras.
The Functions of Numerous Cameras
For Thin Body and Excellent Performance
First, light passes through the phone’s lens into the internal optical system. An optical system is a series of lenses that focus light from an object onto a photosensitive element. The sensor then converts the received light signals into electrical signals and encodes these signals into a string of digital signals that the phone chip can understand. After receiving these digital signals, the chip stores them and turns them into a series of instructions to tell each pixel on the display screen what light to emit. The light emitted by each pixel on the screen comes together to form a complete photo, which is presented before our eyes. There is a big problem lurking in this process, that is, to take a perfect photo, it is necessary to ensure that the light entering the optical system is enough, the optical system is complex enough, which requires a set of optical systems as large as possible and as large as the sensor chip, which runs counter to the concept of the mobile phone becoming lighter and thinner. So how can we continue to improve the shooting ability of the phone without increasing the thickness of the camera, so that the picture is clearer and brighter? Increasing the number of cameras is a good way.
Various Phone Cameras
Main shot: Most of our usual shooting scenes are mainly completed by the main shot, a few special scenes will be useful. So the main shot is very important. This is why the major brands are in the main film and vigorously promote the reason. Through looking at various mobile phones on the market, there are mainly these cameras: main camera, wide angle, telephoto, macro, depth of field, and so on. Main shot: Most of our usual shooting scenes are mainly completed by the main shot (open the camera, the first photo interface is the main shot), a few special scenes will be useful. So the main shot is very important. Wide Angle: Can make the phone’s shooting range (field of view) can be wider. Telephoto: Whether you can narrow the distant scene depends on the zoom of the telephoto camera. Macro: The microscopic world can be well recorded under the macro camera.
Each Performs Its Duties
The cameras on the back of mobile phones have different skills. First, the phone needs to have a main camera to capture the footage to be captured. The clarity of the main camera shooting picture is enough, but the picture may not be enough to highlight the main body, the color is not bright enough, and the outline of the object is not clear enough when shooting the night scene. In addition, a single camera cannot achieve optical zoom when shooting objects that are farther away. So, people add several auxiliary cameras based on the main camera, so that more information can be collected at the same time when taking photos. The location and parameters of these cameras are different, and the pictures taken are very different. This results in an effect similar to that seen by the human eye. For instance, HONOR X8a equips with four different types of cameras, including an Ultra-Clear camera, a Wide&Depth camera, and a Macro camera on the back with an additional Selfie camera in front.
In general, when you want to choose a phone and demand for photos, then you need to realize the function of the camera, the camera types of different phone models will have different effects. Before choosing a phone, you can first understand the functions of these cameras, and then choose the one that suits your heart. Each camera has its function, and phones with four cameras or more will be your better choice. Thanks for reading!
