8 . The method of claim 6 , wherein the first region of the display of the electronic device comprises a left portion of the display of the electronic device, and wherein the second region of the display of the electronic device comprises a right portion of the display of the electronic device.

9 . The method of claim 1 , wherein the first marker comprises a first box surrounding and highlighting the first target shooting object in the first image, and wherein the second marker comprises a second box surrounding and highlighting the second target shooting object in the first image.

10 . The method of claim 1 , wherein the first preview image and the second preview image are displayed in separate areas of the graphical user interface, and wherein the first window is superimposed on one of the first preview image or the second preview image.

11 . The method of claim 1 , wherein the first preview image comprises a zoomed-in image of the first target shooting object in the first image, and wherein the second preview image comprises a zoomed-in image of the second target shooting object in the first image.

12 . The method of claim 1 , wherein the first image comprises content displayed in the first preview image, content displayed in the second preview image, and additional content not displayed in the first preview image and the second preview image.

13 . The method of claim 1 , wherein the first image, the first preview image, and the second preview image comprise a same resolution.

14 . An apparatus, comprising:

a memory configured to store instructions; and

one or more processors coupled to the memory and configured to execute the instructions to:

start a camera application of the apparatus;

acquire, by a camera of the apparatus, a first image;

identify, in a zoom shooting mode of the camera application, a first target shooting object and a second target shooting object in the first image;

display, in response to identifying the first target shooting object and in a graphical user interface, a first preview image comprising the first target shooting object, wherein a first size of the first target shooting object in the first preview image is greater than a second size of the first target shooting object in the first image;

display, in response to identifying the second target shooting object and in the graphical user interface, a second preview image comprising the second target shooting object, wherein a third size of the second target shooting object in the second preview image is greater than a fourth size of the second target shooting object in the first image; and

display, in the graphical user interface, a first window displaying the first image, a first marker marking the first target shooting object in the first image, and a second marker marking the second target shooting object in the first image,

wherein the first preview image, the second preview image, and the first window are displayed in the graphical user interface at the same time.

15 . The apparatus of claim 14 , wherein the one or more processors are further configured to execute the instructions to:

detect a window hiding operation;

hide, in response to detecting the window hiding operation, the first window;

detect a window call-out operation; and

display, in response to detecting the window call-out operation, the first window.

16 . The apparatus of claim 14 , wherein the first image comprises the first target shooting object and the second target shooting object, and wherein the one or more processors are further configured to execute the instructions to:

detect a target shooting object switching operation; and

display, in response to detecting the target shooting object switching operation, the second preview image.

17 . The apparatus of claim 14 , wherein the first image comprises the first target shooting object and the second target shooting object, and wherein the one or more processors are further configured to execute the instructions to:

detect an operation for increasing a quantity of target shooting objects in the first preview image; and

in response to detecting the operation:

display the first preview image in a first region of a display of the apparatus; and

display the second preview image in a second region of the display.

18 . The apparatus of claim 14 , wherein the one or more processors are further configured to execute the instructions to display the first preview image and display the second preview image by displaying the first preview image in a first region of a display of the apparatus and displaying the second preview image in a second region of the display of the apparatus.

19 . The apparatus of claim 14 , wherein the one or more processors are further configured to execute the instructions to display the first preview image and display the second preview image by:

receiving, while displaying the first preview image, a switching operation; and

displaying, in response to receiving the switching operation, the second preview image instead of the first preview image.

20 . A computer program product comprising instructions stored on a non-transitory computer-readable medium that, when executed by one or more processors, cause an apparatus to:

start a camera application of the apparatus;

acquire, by a camera of the apparatus, a first image;

identify, in a zoom shooting mode of the camera application, a first target shooting object and a second target shooting object in the first image;

display, in response to identifying the first target shooting object and in a graphical user interface, a first preview image comprising the first target shooting object, wherein a first size of the first target shooting object in the first preview image is greater than a second size of the first target shooting object in the first image;

display, in response to identifying the second target shooting object and in the graphical user interface, a second preview image comprising the second target shooting object, wherein a third size of the second target shooting object in the second preview image is greater than a fourth size of the second target shooting object in the first image; and

display, in the graphical user interface, a first window displaying the first image, a first marker marking the first target shooting object in the first image, and a second marker marking the second target shooting object in the first image,
