It should be noted that the basic characteristics of shooting with the wide-angle fixed-focus lens are that the lens viewing angle is large and the visual field is wide. The range of scenes observed from a certain viewpoint is much larger than what the human eye sees from the same viewpoint. The wide-angle fixed-focus camera also has the characteristic of long depth of field, and can show a quite large clear range. The present embodiment is for solving the user experience that the wide-angle fixed focus camera previews, takes a picture or records a video in a close range, and/or, the wide-angle fixed focus camera is regarded as the main auxiliary camera of taking a picture under the double-shot mode, and the problem that the depth of field effect is poor or there is no depth of field effect when taking a picture in a close range. Through presetting intelligent logic selection strategy, first camera and/or the second camera of dynamic switching are shot, promote the user and shoot the experience of shooing of distance in the difference.

the first camera is in a use mode of combined work with the second camera, and the definition of the preview images of the first camera and the second camera is obtained.
Note that the shooting data includes a shooting distance between the shooting object and the first camera and/or a sharpness of the preview image. The shooting distance may be obtained based on ranging techniques such as laser ranging, dual-shot TOF ranging, and the like. When the first camera is in different use modes, the obtained shooting data are different. Optionally, when the first camera or the second camera is used alone for shooting, shooting data such as shooting distance and/or definition of a preview image can be acquired for evaluating whether preset conditions are met.

the times that the shooting distance is smaller than the preset distance are larger than the preset times;
the times that the shooting distance is greater than the preset distance are greater than the preset times;

It should be noted that, in this embodiment, when the first camera is used alone to take a picture, if the number of times that the shooting distance is smaller than the preset distance is greater than the preset number of times, it indicates that the distance between the shooting object and the camera is short, and the second camera needs to be switched to take a picture, so as to avoid imaging blur. If the shooting distance is less than or equal to the preset distance, the situation that the shooting distance is closer to the shooting object is occasionally detected or not detected, the shooting advantage of the first camera, namely the wide-angle fixed-focus camera, can be fully utilized, and the second camera does not need to be switched to be used for shooting.
Optionally, when the first camera is used alone to take a picture, the sharpness of the preview picture of the first camera may be evaluated first. Selecting a history preview image which is clearly imaged by the first camera, and storing the definition of the history preview image as an evaluation standard. And if the deviation degree between the definition of the preview image of the first camera and the definition of the historical preview image of the first camera is greater than a preset threshold value, continuously acquiring the preview image of the second camera. If the definition of the preview image of the first camera is smaller than that of the preview image of the second camera, the second camera needs to be switched to shoot. Of course, when detecting whether the shot data meets the preset conditions, only the preview image of the first camera and the preview image of the second camera may be compared. And if the definition of the preview image of the first camera is smaller than that of the preview image of the second camera, switching to the second camera for shooting.
Optionally, in step 203, when the first camera is in the use mode of suspended operation, according to the detection result, performing shooting by using the first camera and/or the second camera, including at least one of:
the times that the shooting distance is larger than the preset distance are larger than the preset times, and the shooting is switched to the mode that the first camera is recovered to be used for shooting;

and the shooting distance is greater than the preset distance for a number of times greater than the preset number of times, and the shooting is resumed to the shooting by using the first camera and the second camera.
It should be noted that, in this embodiment, when the first camera pauses to take a picture, the second camera is used to take a picture alone. If the shooting distance is greater than the preset distance for more than the preset times, the shooting object is far away from the camera, and the first wide-angle camera can be used for shooting so as to obtain a large-field and clear-imaging image. If the number of times that the shooting distance is greater than the preset distance is less than or equal to the preset number of times, which indicates that a situation that the shooting object is far away from the shooting object is occasionally detected or not detected, the second camera needs to be kept for shooting.
Optionally, in step 203, when the first camera is in a use mode working in combination with the second camera, shooting with the first camera and/or the second camera according to the detection result, where the shooting includes at least one of:

the deviation degree between the definition of the preview image of the first camera and the definition of the historical preview image of the first camera is larger than a preset threshold value, the definition of the preview image of the first camera is smaller than the definition of the preview image of the second camera, and the second camera is used for shooting;
the definition of the preview image of the first camera is smaller than that of the preview image of the second camera, and shooting is carried out by using the second camera.
It should be noted that, in this embodiment, when the first camera and the second camera are used to perform combined shooting, if the number of times that the shooting distance is smaller than the preset distance is greater than the preset number of times, it indicates that the distance between the shooting object and the camera is short, and it is necessary to switch to the second camera to perform shooting alone, so as to avoid imaging blur. If the shooting distance is less than or equal to the preset distance, the condition that the distance to the shooting object is detected occasionally or is not detected occasionally is indicated, the shooting advantage of the first camera, namely the wide-angle fixed-focus camera, can be fully utilized, and the combined shooting by using the first camera and the second camera can be kept.
Fig. 4 is one of specific flow diagrams of the photographing method shown according to the first embodiment. As shown in fig. 4, the wide-angle camera is first turned on to take a picture, i.e., the first camera is used alone to take a picture. And then opening the TOF laser sensor, and acquiring the distance between the object to be shot and the wide-angle camera through the TOF laser sensor. If the distance between the object and the wide-angle camera is less than a depth-of-field distance threshold value M, for example, M is 70cm, and the number of times of detection that the distance is less than the depth-of-field distance threshold value is greater than N times, for example, N is 3 times, that is, the preset condition is satisfied: if the shooting distance is less than the preset distance for more than the preset times, the shooting object is close to the camera, the main camera needs to be opened, and the shooting lens is switched from the wide-angle camera to the main shooting lens, so that imaging blur is avoided. Optionally, after the photographing lens is switched from the wide-angle camera to the main camera, the distance between the object to be photographed and the wide-angle camera is detected to be greater than the depth-of-field distance switching threshold M by the TOF laser sensor, and when the number of times N greater than the depth-of-field distance threshold is detected, the preset condition is satisfied: the number of times that the shooting distance is smaller than the preset distance is smaller than or equal to the preset number of times, which indicates that a situation that a short distance to the shooting object is occasionally detected or not detected, is switched from the main camera to the wide-angle camera.
Optionally, when the first camera and the second camera are used for combined photographing, the definition of the preview picture of the first camera may be evaluated first.

And if the deviation degree between the definition of the preview image of the first camera and the definition of the historical preview image of the first camera is greater than a preset threshold value, continuously acquiring the preview image of the second camera. If the definition of the preview image of the first camera is smaller than that of the preview image of the second camera, the shooting needs to be switched to the use of the second camera for shooting alone. Of course, when detecting whether the shot data meets the preset conditions, only the preview image of the first camera and the preview image of the second camera may be compared. And if the definition of the preview image of the first camera is smaller than that of the preview image of the second camera, switching to the use of the second camera for shooting alone.

If the distance between the object and the wide-angle camera is smaller than a depth-of-field distance threshold value M, for example, M is 60cm, and the number of times of detection smaller than the depth-of-field distance threshold value is greater than N times, for example, N is 5 times, it indicates that the distance between the object to be shot and the camera is short, and the main shooting lens needs to be switched. And closing the double-camera processing flow of the main camera and the wide-angle camera, and switching the double-camera blurring processing algorithm to a main-camera single-camera blurring effect to avoid imaging blurring. Optionally, after the photographing lens is switched from the wide-angle camera to the main camera, when it is detected that the distance between the subject and the wide-angle camera is greater than the depth-of-field distance switching threshold M and the number of times N greater than the depth-of-field distance threshold is detected, the main camera independent photographing mode is switched to a dual-photographing blurring mode in which the main camera and the wide-angle camera are combined for photographing, so that switching between true dual-photographing blurring and main-photographing single-photographing blurring is achieved.
