The embodiment of the application provides a blurring processing method, which is applied to electronic equipment, wherein the electronic equipment comprises at least two cameras, and different cameras correspond to different focal segments, as shown in fig. 1, the method comprises the following steps:
step 101: and acquiring a first display size of the shot object, wherein the first display size is the display size of the shot object acquired by a first camera in the at least two cameras.
As shown in fig. 2, the electronic device of the embodiment of the present application includes a plurality of cameras 210 with different focal lengths, optionally a plurality of the cameras are arranged in two rows, the uppermost camera in each row of cameras is the main camera, and the focal lengths of the cameras arranged below the main cameras are gradually increased. Of course, the plurality of cameras may be arranged in other arrangement manners, and is not limited in particular here.
Here, by providing a plurality of cameras of different focal lengths on the electronic apparatus, a variable double shooting baseline can be realized. The base line between the main camera and the lowest camera in each row of cameras is longest, and double-shooting blurring can be performed on objects with long distances. The base line refers to the distance between two cameras when the two cameras are used for shooting.
In this step, the first camera may be a preset camera, that is, a user sets a camera in advance among the plurality of cameras to take a picture.
For example, as shown in fig. 3, a user opens a camera and clicks a blurring mode, at this time, a main shooting picture (a shooting preview interface corresponding to a first camera) is displayed on a main interface, and a picture (a sub-shooting picture) shot by another camera is displayed on an upper right corner of the main interface, where a display area corresponding to the sub-shooting picture is smaller than a display area corresponding to the main shooting picture, at this time, a first display size of a shooting object in the main shooting picture is obtained, where the first display size is used to indicate area information occupied by the shooting object in the shooting preview interface, and a distance between the shooting object and the electronic device can be determined by the first display size, and the distance between the shooting object and the electronic device is inversely proportional to the first display size, that is, the farther the first display size is smaller.
Step 102: and under the condition that the first display size is smaller than a first preset display size, selecting a target second camera from the at least two cameras, wherein the second display size of the shot object collected by the target second camera is larger than the first display size.
Here, if the first display size is smaller than the first preset display size, which indicates that the object to be shot is far from the electronic device, that is, the object with a long distance is subjected to double shooting blurring at this time, a target second camera with a proper focal length is selected from the at least two cameras, so that the double shooting blurring processing is performed on the target second camera.
The second display size of the shot object collected by the target second camera is larger than the first display size of the shot object collected by the first camera, so that the shot object can be amplified, and the shot object with better details can be obtained.
Step 103: and carrying out photographing blurring treatment according to the distance between the target second camera and the first camera.

determining a second focal length and a second field angle corresponding to the second display size according to the corresponding relation between the focal length and the field angle and the display size of the shot image;
and determining a second target camera according to the second focal length and the second field angle.
In the embodiment of the present application, in order to obtain a better blurring effect, a camera with a proper focal length needs to be selected to zoom in on a photographic subject (since after the photographic subject is zoomed in, more details of the photographic subject, the outline of the photographic subject, and the like can be obtained, and thus the photographic subject is conveniently distinguished from a background image), that is, a camera with a display size of a photographic image larger than the first display size needs to be selected. Here, the display size of the image captured by each camera may be determined in advance from the focal length and the angle of view of each camera, and a correspondence relationship between the focal length, the angle of view, and the display size of the captured image may be established, and then, based on the correspondence relationship, the second focal length and the second angle of view corresponding to the second display size may be determined, and the target second camera corresponding to the second focal length and the second angle of view may be selected.
Optionally, selecting a target second camera among the at least two cameras includes:
and under the condition that a plurality of second cameras exist in the at least two cameras, selecting a second camera with the largest distance from the first camera from the plurality of second cameras as the target second camera, wherein the second display size of the shot object collected by the second camera is larger than the first display size.
In the embodiment of the application, the larger the base line between the two cameras is, the larger the parallax is, and the more favorable the blurring of the remote object is, so that the second camera with the largest base line is selected as the target second camera under the condition that a plurality of second cameras exist, and the better blurring effect is favorably obtained.
Optionally, after acquiring the first display size of the photographic subject, the method further includes:
and displaying prompt information under the condition that the first display size is smaller than a second preset display size, wherein the prompt information is used for prompting the replacement of the first camera.
