Problems solved by technology

However, in the prior art, when the user uses the front camera to take a selfie, the short distance of the selfie will cause the head portrait of the photo to be larger, which will affect the appearance; Open a certain distance, the operation is inconvenient, the posture is unsightly and easy to be noticed
Or you can use a selfie stick to take selfies, but the compatibility of the selfie stick is poor, and it is inconvenient to carry. Many public places prohibit carrying a selfie stick to take pictures, and when using the selfie stick to press the shutter to take a selfie, the stick will shake with the force of the thumb. Can't achieve a good selfie effect

Abstract

The embodiment of the invention provides a front camera-based image processing method and a mobile terminal. A front camera is a zoom camera; and the method comprises the steps of carrying out focal distance adjustment on the front camera according to a focal distance adjustment instruction when the focal distance adjustment instruction is received; and shooting image data by adopting the adjusted front camera. According to the front camera-based image processing method and the mobile terminal, the front camera is the zoom camera, and focal distance adjustment is achieved through the front camera, so that the problem that focal distance adjustment cannot be achieved by the front camera is solved, the front camera can obtain an image with a proper size under the close-range self-portrait condition, and the self-portrait effect of the front camera is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an image processing method based on a front camera and a mobile terminal. Background technique [0002] With the continuous development of mobile terminal technology, the camera functions of the mobile terminal are becoming more and more abundant, and users frequently use the mobile terminal to take pictures on a daily basis. [0003] When a user uses a mobile terminal to take a selfie, most of them use the front camera. However, in the prior art, when the user uses the front camera to take a selfie, the short distance of the selfie will cause the head portrait of the photo to be larger, which will affect the appearance; Open a certain distance, the operation is inconvenient, the posture is unsightly and easy to be noticed. Or you can use a selfie stick to take selfies, but the compatibility of the selfie stick is poor, and it is inconvenient to carry. Many pub...
