[0079] The present invention provides a focus controller for communicating with a focus motor. Figure 1 , the focus controller comprises:

[0080] Main body 100;

[0081] The first focus adjustment component 200 and the second focus adjustment component 300 are disposed on the main body 100;

[0082] The control component 400 is disposed on the main body 100 and is used to generate a first focus control signal according to the rotation of the first focus adjustment component 200 or to generate a second focus control signal according to the rotation of the second focus adjustment component 300. The first focus control signal and the second focus control signal are used to control the operation of different focus motors.

[0083] The focus controller proposed in this embodiment can be used as a component of the focus system and communicated with the focus motor. The user can control the focus motor by operating the focus controller, and the focus motor then drives the lens of the photographic device to rotate to complete lens focusing or zooming. The communication connection between the focus controller and the focus motor can be a wired connection or a wireless connection, which is set according to the actual situation.

[0084] The focus controller includes a main body 100, a first focus adjustment component 200, a second focus adjustment component 300 and a control component 400, wherein the structural structure and appearance of the main body 100 can be set according to actual conditions, and there is no limitation on this. For example, the main body 100 can be in the shape of a handle, an ellipse or other shapes. The first focus adjustment component 200 and the second focus adjustment component 300 can be exposed outside the main body for user operation and rotation. The structural structure, setting form, etc. of the first focus adjustment component 200 and the second focus adjustment component 300 can be the same or different, and the positions of the first focus adjustment component 200 and the second focus adjustment component 300 on the main body 100 can be set according to actual needs. For example, Figure 1 As shown, the first focus adjustment component 200 and the second focus adjustment component 300 are arranged on different sides of the main body 100, and the first focus adjustment component 200 is located at the upper part of the main body 100, and the second focus adjustment component 300 is located in the middle part of the main body 100. The control component 400 can be arranged in the main body 100, and the control component 400 generates a focus control signal according to the rotation of the focus adjustment component. When the focus control signal is sent to the focus motor, the focus motor can be controlled to work, and the focus motor further drives the lens of the photographic device to rotate.

[0085] In actual application, the focus controller can be communicatively connected with a focus motor, and the user operates the first focus adjustment component 200 or the second focus adjustment component 300 to rotate, and the control component 400 generates a first focus control signal or a second focus control signal accordingly, and the focus motor receives the first focus control signal or the second focus control signal to work; the focus controller can also be communicatively connected with two different focus motors, and the user can operate the first focus adjustment component 200 to rotate, and one of the focus motors receives the first focus control signal to work, and can operate the second focus adjustment component 300 to rotate, and the other focus motor receives the second focus control signal to work.

[0086] That is, the focus controller can be connected to multiple focus motors for communication, wherein when the first focus adjustment component 200 rotates, the control component 400 can generate a first focus control signal, and when the second focus adjustment component 300 rotates, the control component 400 can generate a second focus control signal, and the focus controller can send the first focus control signal and the second focus control signal to different focus motors, respectively, to control the different focus motors to work. By controlling the first focus adjustment component 200 and the second focus adjustment component 300 of the focus controller, at least two focus motors can be controlled to work, thereby improving the one-to-many control performance and focusing effect. Compared with the configuration of multiple focus controllers, the installation is simple, time-saving and convenient, and there is no need to frequently switch the control, which saves operation time and makes the operation convenient.

[0087] Of course, as other implementation schemes, on the basis of providing the first follow focus adjustment component 200 and the second follow focus adjustment component 300, the follow focus controller may also be provided with a third follow focus adjustment component or even a fourth adjustment component to control more follow focus motors to work. That is, according to the basic scheme of the present application, those skilled in the art may appropriately increase the number of follow focus adjustment components on the follow focus controller according to actual needs.

The user can operate the first focus adjustment component 200 on the first main body 110 to rotate for focus adjustment control, or operate the second focus adjustment component 300 on the second main body 120 to rotate for focus adjustment control. When the first main body 110 is installed on the second main body 120, the focus controller can be used as one focus controller; when the first main body 110 is removed from the second main body 120, the focus controller can be disassembled into two, and the first main body 110 and the second main body 120 can be used as two focus controllers respectively. That is, the focus controller can be used as one or two focus controllers according to actual needs, which can meet more usage scenarios and improve the user experience.

[0090] Furthermore, the structural construction and appearance of the first body 110 and the second body 120 can be set according to actual conditions, and there is no limitation on this.
