With the rapid development of science and technology today, a wide range of high-tech products are gradually applied to various fields and into people's daily life. For example, the mobile phone has gradually added a camera function instead of a camera from the original single communication function. An artifact for taking pictures while traveling, the original single lens camera of the mobile phone has been increased to dual lens cameras. Let me introduce the difference between dual lens camera and single lens camera.
1. The difference between dual lens camera and single len camera
a. First of all, the pixels of the photos taken by the dual lens cameras can still only reach the pixels of a single lens camera, that is to say, the dual lens cameras are 5 mega pixels, and the final photos are still 5 mega pixels, not 10 mega. And a single lens camera with 10 megapixels can get 10 megapixel photos; therefore, there is no processing of superimposing pixels between the dual lens camera and the single lens camera. Generally, the pixel size of the main imaging camera is the pixel size of the photo taken;
b. There are several types of dual lens camera configurations. The main camera is responsible for shooting, and the auxiliary camera is responsible for measuring the depth of field and spatial information; there are also settings where the auxiliary camera is a telephoto or ultra-wide-angle camera to meet different photography needs.
2. The dual lens camera configuration has the following advantages
a. Since a camera adopts the design of recording depth of field and space, it can be used to measure the range of depth of field and space information, so it can realize taking pictures first and then focusing. Users only need to click on the picture edit in the finished film to select Focus on the focus to re-create the photo; of course, the depth of field information can also be used to achieve a good blur effect, and the background blur under the large aperture of the camera can be realized through software synthesis.
b. One of the cameras in some mobile phones adopts a larger aperture design, which can bring in more light. In low-light environments, the imaging picture has less noise and a purer picture, achieving better night scene shooting effects.
c. There are also some mobile phones with telephoto and ultra-wide-angle cameras that can meet different shooting needs.
