Why are the photos taken by the front camera and the rear camera of the mobile phone very different?

Because their pixels are different, they use different apertures. Pixel is the main parameter of camera. The resolution (pixels) is mainly determined by the image sensor. The higher the resolution, the finer the image and the better the effect, but the image takes up more storage space. Generally speaking, camera pixels are the largest pixels in camera mode, and pixels in photography (video shooting) are usually smaller.

In general, the mobile phone rear camera is superior to the front camera in all aspects. Except for some models that mainly take selfies, the pixels of the front camera of the mobile phone are lower than those of the rear camera, and it has only general functions, but it does not have the function of configuring the rear camera by the mobile phone manufacturer.

The resolution of mobile phone camera often uses the special terms of image resolution (such as CIF, VGA, etc. ) to represent the resolution (pixel = resolution multiplied by the length, width and sum, such as: 640X480=307200, that is, 30W pixels).

Influencing factors of mobile phone camera

1, aperture

The aperture of a mobile phone camera is similar to the lens of a camera, and its value is inversely proportional to the aperture. However, due to the limitation of structure and volume, the aperture of the lens in modern mobile phones is generally fixed. So the size of its aperture will directly affect the effect of the camera.

2. Shutter

Shutter time and frame rate are inversely proportional, so shutter speed will also affect the effect of taking pictures on mobile phones to some extent.

Step 3: Lens

Aperture and wide angle are two important parameters in a camera. Wide angle is closely related to optical lens, so the design of optical lens will also affect the performance of mobile phone camera.

4. Focus motor

The accuracy and speed of motor focusing will directly affect the imaging effect of mobile phone, forming different user feelings. Therefore, the design of focus motor is also one of the important contents to optimize the performance of mobile phone camera. ?
