The face is controlled by stretching the left scroll leftwards and rightwards, the left scroll is stretched leftwards, and the width of the face is increased (namely the face is enlarged); if the left scroll bar is pushed to the right, the width of the face is reduced (i.e., the face becomes smaller); the whole process only adjusts the size of the face of the portrait, the background is unchanged, and the processing effect is as shown in fig. 4.
And the right reel continues to stretch rightwards, and when the stretching length of the right reel reaches a third threshold value B3, the integral stature adjusting mode is entered. The body width is controlled by stretching the left scroll leftwards and rightwards, the left scroll is stretched leftwards, the whole body of a person can be widened, and the person can become fat; if the left reel is pushed to the right, the whole figure of the person becomes narrow, namely the person becomes thin. The whole process only adjusts the weight of people, the background is unchanged, and the treatment effect is shown in figure 5. Wherein B1< B2< B3, namely when the right side reel is stretched from 0cm to the right, different parts of the portrait can be adjusted along with the stretching length, and when the right side reel is stretched to the utmost, all preset parts of the whole portrait are adjusted.
In step 103, the target area is subjected to image processing in accordance with the target adjustment parameter, and a target image is output.
In the embodiment of the application, when a photographing instruction is received, image processing can be performed on a target area according to a target adjustment parameter, and a target image is output, wherein the photographing instruction can be triggered in multiple ways, for example, a photographing icon on a screen is clicked, or a left side scroll is pushed to the right, all the left side scrolls are rolled up, and the photographing instruction is started.
In the embodiment of the application, in a photographing scene, when the target area is subjected to image processing according to the target adjustment parameter, only the target area can be adjusted, and the background is kept unchanged.
In the embodiment of the application, under the scene that the electronic equipment is used for shooting people, the whole stature, the face and the legs of the shot portrait can be stretched in the shooting process, the stretching proportion can be adjusted in real time, and the most suitable parameters are selected; meanwhile, the auxiliary user does not need to perform post-processing after shooting is completed, so that the legs and the body of the portrait can be more harmonious, and the shooting experience of the user is improved.
