[0003] Nowadays, mobile terminals such as mobile phones are generally equipped with two cameras, a front camera and a rear camera. The front camera is mainly used when the user takes a selfie. quality requirements

[0004] The pixels of the rear camera are much higher than that of the front camera, and the photos taken can meet the requirements of users.
