In one embodiment, when the retractable display screen is in the extended state, the retractable display screen includes a fixed display area and an extended display area, the first display area may correspond to the fixed display area, the fixed display area may not change in size, and the real-time preview image may be displayed in the fixed display area without affecting the display size of the preview image due to extension or contraction of the retractable display screen.

The second display area may correspond to an extended display area for displaying the reference image to assist the user in obtaining a satisfactory preview image. The reference image is the image with the highest reference value selected according to the current shooting image. Because the telescopic display screen is in an extension state and is in a contraction state relative to the telescopic display screen, the extension display area is increased, and therefore the extension display area can be fully utilized to provide assistance for a user to shoot images.

When the telescopic display screen is in an extending state, the telescopic display screen can be fully unfolded, and the telescopic display screen can also be partially unfolded.

For example, the first display area may be 2/3 of the display area of the current retractable display screen, and the second display area may be 1/3 of the display area of the current retractable display screen, so that the preview image is displayed in the first display area, and the reference image is displayed in the second display area. The specific proportion can be set according to the needs of users, and the embodiment of the application does not limit the specific proportion.

It should be noted that, after dividing the first display area and the second display area according to a preset ratio based on the display area of the retractable display screen, the user may also need to adjust the division ratio of the first display area and the second display area according to the current shooting requirement, for example, the user may want to display a preview image in a larger area during the shooting process, or the user may also want to display a reference image in a larger area. Thus, the electronic device may identify whether an adjustment instruction for the first display area and the second display area is received; if yes, corresponding adjustment is carried out on the first display area and the second display area according to the adjustment instruction. Thereby also improving the flexibility of image capturing.

In one embodiment, when the second display area may display a plurality of complete reference images, the reference images may be displayed according to a usual usage habit of the user, for example, in the order of the usage frequency from high to low in the second display area. It can be understood that the higher the frequency of use, the more likely the reference images are selected by the user, so that the frequency of use of the reference images is displayed in a sequence from high to low, and the reference images conform to the use habit of the user, wherein the frequency of use of the reference images can be generated according to the historical use record of the user.

In one embodiment, the electronic device may prompt the user to score the reference image and record the score of the reference image that the user has scored, and may dynamically update the user's score. It can be understood that the reference images with higher scores indicate that the user likes, so that the reference images can be displayed in the second display area in an arrangement manner according to the order of the user scores from high to low, so that the user can select the liked reference images more quickly, and the efficiency of selecting the reference images by the user is improved.

In one embodiment, a large number of reference images may be displayed in a classified manner for convenience in quickly selecting a satisfactory reference image according to current photographing needs. Specifically, identifying category information of the reference image; and the reference images are displayed in the second display area according to the classification of the category information, and the searched images are displayed in the second display area as the reference images. For example, the shooting scenes of the reference images are identified, and the reference images can be classified according to different shooting scenes, for example: seaside, sunset, park, forest, street view, etc. For example, the photographed person of the reference image is identified, and the reference image may be classified according to different person types, for example: different character types such as boys, girls, elders, children, and conjunctions. For example, the shooting subjects of the reference images are identified, and the reference images can be classified according to different shooting subjects, for example: different shooting subjects such as figures, animals, flowers, buildings, food, and the like.

In the embodiment of the application, when the electronic equipment is in a shooting state, the telescopic display screen of the electronic equipment is in an extending state, so that a larger display area can be provided. The retractable display screen is divided into a first display area and a second display area, a preview image is displayed in the first display area, and a reference image is displayed in the second display area. The reference image is selected according to the current preview image, is matched with the current preview image best, and has the highest reference value. For example, a reference image of a close shooting scene is selected according to the shooting scene of the preview image. Therefore, when the current image is shot, the user can be assisted in adjusting the preview image according to the reference image, so that a new preview image which better accords with the preference of the user is obtained, the satisfaction degree of the user on the shot image is improved, and the flexibility of the shot image is also improved.
