Background As macro photography technology matures, it becomes possible to implement macro photography on electronic devices (e.g., cell phones). The micro-distance shooting can shoot micro objects in an ultra-short distance, and extremely good shooting experience is brought to users. In the related art, a macro switching strategy of the electronic equipment is that for equipment without a laser device, the macro switching can be judged based on a distance value (namely, object distance) obtained by image phase detection and conversion, and for equipment with the laser device, the macro switching can be judged based on a distance value (namely, object distance) of laser ranging. However, the selection of the macro switching mode based on whether the laser device is included may result in inaccurate macro mode switching in a specific scene, and it is difficult to ensure the macro switching effect in the specific scene. Disclosure of Invention The embodiment of the application provides a micro-distance mode switching method and device, which can improve the accuracy of micro-distance mode switching and further improve the user experience. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: A first aspect provides a macro mode switching method, which is applied to electronic equipment, wherein the electronic equipment comprises a first camera, a second camera and a laser device, and the method comprises the steps of responding to a first operation, acquiring a first view-finding picture by using a first camera, judging whether the first view-finding picture belongs to the first scene or not, wherein the first scene comprises a multi-depth-of-field scene, the multi-depth-of-field scene represents that a plurality of objects in a depth range of the first view-finding picture are different from the electronic equipment, determining an object distance according to phase difference PD data of the first view-finding picture when the first view-finding picture belongs to the first scene, switching to the second camera to acquire the second view-finding picture in a macro mode when the object distance is smaller than or equal to a first preset threshold, and measuring the object distance according to the laser device when the first view-finding picture does not belong to the first scene, and switching to the second camera to acquire the second view-finding picture in the macro mode when the object distance is smaller than or equal to the first preset threshold. According to the method provided by the embodiment of the application, whether the first view-finding picture acquired by the first camera (for example, the main camera) belongs to a first scene (for example, a multi-depth-of-field scene) can be judged, the object distance can be determined according to the phase difference PD data of the first view-finding picture under the condition that the first view-finding picture belongs to the multi-depth-of-field scene, the second view-finding picture is acquired in a micro-distance mode by switching to the second camera under the condition that the object distance is smaller than or equal to a first preset threshold value, the object distance can be measured according to the laser device under the condition that the first view-finding picture does not belong to the multi-depth-of-field scene, and the second view-finding picture can be acquired in a micro-distance mode by switching to the second camera under the condition that the object distance is smaller than or equal to the first preset threshold value. Therefore, the problem that the laser ranging is inaccurate under the multi-depth-of-field scene to cause the error switching to the macro mode can be avoided, and the macro mode switching accuracy under the multi-depth-of-field scene can be improved, so that the user experience is improved.
