It should be noted that the default use data of the camera specifically refers to a camera which is set by the system and allowed to be turned on corresponding to the scene feature information. Here, different scene feature information corresponds to different cameras that are allowed to be turned on. For example, if the scene feature information indicates that the current shooting environment of the electronic device is outdoor, the camera allowed to be started is a wide-angle camera; the scene characteristic information indicates that the current electronic equipment posture is in a negative direction with the electronic equipment as a coordinate axis and the screen of the electronic equipment facing to the Y axis.

if yes, go to step 202; otherwise, ending the flow;
step 202, acquiring the distance between the electronic equipment and the face of a user;
step 203, when the distance is within the range of using the front camera, starting the front camera of the electronic equipment;
for example, if the user climbs a mountain and goes high and out, stands on the mountain and finds that landscape under the mountain is good, and then takes out the mobile phone to prepare for taking a picture, at this time, if the mobile phone detects that the mobile phone is far away from the face of the user, namely, within the range of using the front camera, the user is considered to want to take a self-picture, and the front camera is turned on.

If the current posture of the mobile phone is detected to be the coordinate axis of the electronic equipment, the screen of the mobile phone faces to the negative direction of the Y axis. That is to say, the screen of the current electronic device faces the ground, and the lens of the rear camera faces the sky, then the camera which is included in the default use data and is allowed to be turned on is a long-focus camera, or the use probability of the corresponding long-focus camera included in the default use data of the camera is high, and at this time, a large weight is given to the long-focus camera; if the current posture of the mobile phone is detected to be the coordinate axis of the electronic equipment, the screen of the mobile phone faces the positive direction of the Y axis. That is to say, the lens of the rear camera of the current electronic device faces the ground, and then the usage probability of the corresponding tele camera included in the default usage data of the camera is small, and at this time, a smaller weight is given to the tele camera.
Step 205, acquiring historical camera use data corresponding to a first shot image stored locally, wherein the similarity between the scene feature information of the first shot image and the scene feature information is greater than a first preset threshold;
here, the following are exemplified: the method comprises the steps that photo data stored in a local photo album and a photo album are checked by a mobile phone, if the similarity between scene characteristic information corresponding to the photo data and the current scene characteristic information is larger than a first preset threshold value, namely a user takes a picture in a shooting scene or a similar shooting scene before, and if a camera used by the user is determined to be a main camera according to shooting records in the photo data, the main camera is given a larger weight.
Step 206, acquiring recommended use data of a camera corresponding to a second shot image shot by other users, wherein the similarity between the scene characteristic information of the second shot image and the scene characteristic information is greater than a second preset threshold value;
here, if the user has not taken a picture of the shooting scene where the current mobile phone is located or a similar shooting scene, the camera used by other users in the shooting scene or the similar shooting scene can be obtained through the network, and is recommended to the user with a larger weight.
Step 207, calculating default use data of the cameras, historical use data of the cameras and recommended use data of the cameras to obtain the weight of each camera in the rear camera;
here, for the calculation of the camera weight, reference may be specifically made to the description of the relevant part of the above embodiment, and details are not described here.
And 208, determining the camera with the largest weight as a target camera, and starting the target camera, wherein the target camera is one of a main camera, a wide-angle camera and a telephoto camera.
