At present, in the process of shooting by a user at multiple machine positions, when the user needs to control a plurality of shooting devices to preview focusing control of a main shooting person, the user is generally required to control the shooting device at a main machine position to make focusing setting, and then control the shooting devices at other auxiliary machine positions to make focusing. Or the shooting equipment of the main machine position and the shooting equipment of the auxiliary machine position are set to be automatically focused, and the shooting equipment of each machine position automatically finishes focusing of people in the preview area according to the focusing capacity of the equipment.

The multi-machine shooting focusing control method has the defects, for the first scheme, after the main shooting equipment is well focused, each auxiliary machine needs to be specially used for adjusting focusing parameters, and particularly when the auxiliary machine is more or the distance between the auxiliary machines is far, the operation control of a user is inconvenient, the operation is complex, and the shooting efficiency is low. For the second scheme, the shooting devices of the respective machine positions respectively and automatically complete the focusing of the people in the preview area according to the focusing capabilities of the devices, which may cause inconsistent focusing effects, for example, the main machine position shooting device focuses on a human body, and the auxiliary machine position focuses on a background.

Based on the technical problem, the application provides a focusing control method, a focusing control device, an electronic device and a storage medium, which are applied to a shooting device.

The following describes in detail a focus control method, a focus control device, an electronic apparatus, and a storage medium according to embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a focus control method provided in an embodiment of the present application, and as shown in fig. 1, the embodiment of the present application provides a focus control method applied to a first electronic device, where the first electronic device may be a shooting device for shooting a host location in a scene with multiple locations, such as a smart phone, a camera, a video camera, and the like, and the following description takes the video camera as an example, and the method includes:

For example, fig. 3 is one of the interface schematic diagrams of the focusing control method provided in the embodiment of the present application, and as shown in fig. 3, a focusing process on the main camera a may be triggered by clicking the first focusing object a, and after the focusing is completed, the focusing frame displays a focusing completion state of the main camera. When the user needs to control the secondary camera to perform focusing operation, the user may operate the primary camera a to determine a focusing object of the secondary camera by operating the first input, for example, the user may click the first focusing object a, may double click the first focusing object a, or may tap the first focusing object a.

Step 102, responding to the first input, and sending a first message to the second electronic equipment; the first message includes information of the first focus object.

Specifically, the master camera a receives a first operation by the user, and then transmits a first message including information on the first object to be focused to the slave camera. For example, fig. 4 is a second interface schematic diagram of the focus control method provided in the embodiment of the present application, and as shown in fig. 4, double-clicking a first focus object a may trigger the primary camera a to send a synchronous focus (which may also be referred to as "focus tracking") request message (a first message) to the secondary camera B and the secondary camera C, respectively.

For example, the identification of the sub camera which is successfully focused in synchronization is displayed, and the identification of the sub camera which is not successfully focused in synchronization is not displayed; or the mark of the auxiliary camera which is successfully focused in the synchronization mode is displayed in a first pattern/color, shape and other modes, and the mark of the auxiliary camera which is not successfully focused in the synchronization mode is displayed in a second pattern/color, shape and other modes; and displaying the mark of the auxiliary camera which is successfully focused synchronously.
