It is to be understood that the elements may be "connected", "coupled" or "connected".

First, referring to FIG. 1, a camera lens remote control apparatus according to an exemplary embodiment of the present invention may include a motor unit 20, a transmission module 30, and a reception module 40 which may be installed to be detachably attached to the camera 10. It characterized in that it comprises a).

First, the camera 10 of the present invention is equipped with a plurality of control wheels for controlling zooming, focusing, and iris of a lens included for capturing an image.

Zoom means a concept for arbitrarily changing the size of a subject even when the camera and the subject are fixed at the same time by changing the focal length of the lens. Focusing is a concept for rotating and focusing a focusing ring attached to a lens barrel of a camera and focusing the camera to clearly photograph a subject.

The iris means a mechanism for adjusting the amount of incident light entering the imaging surface with a diaphragm, that is, a metal plate mounted between the camera lenses.

The camera 10 of the present invention is equipped with a control wheel for controlling zoom, focusing and iris as described above. In general, the control wheel can be rotated manually by the photographer while adjusting the zoom, focusing and iris to the desired degree.

The motor unit 20 is connected to a plurality of motors in a series connection network. A plurality of motors may be installed to be detachable for each of the aforementioned control wheels. The motors are each connected to a controller, and the controller rotates the motors according to control commands transmitted according to the above network.

The motors are fastened to each control wheel so that the control wheels interlock when the motor rotates to control zoom, focusing and iris.

The serial connection method refers to a network method in which a controller of a motor transmits and receives data, and a plurality of motors are connected to each other through a serial network.

That is, the control commands are not transmitted to different lines, the motors are each located on one line, and the control commands are transmitted on one line. The controller installed in each node of the line catches the control command transmitted and receives it if it is its own control command and controls the motor according to the control command.If it is not its own control command, the controller continuously sends the control command to the line through the output port. Will be delivered. Description of this will be described in detail in the following description regarding the delivery of the receiving module and the control command.

On the other hand, the transmission module 30 may be located remotely from the motor unit 20, the receiving module 40 and the camera 10, to remotely control the operation of a plurality of motors included in the motor unit 20 And sending means for sending out a control command for the input and input means for inputting a control command.

Zooming, focusing and iris of the lens are controlled in accordance with the rotation of each of the plurality of motors installed in the control wheel of the camera 10. A user who controls the camera 10 may input a control command for each motor through an input means of the transmission module 30.

The control command input through the input means is transmitted to the motor unit 20 via the sending means.

At this time, since a plurality of motors of the motor unit 20, specifically, the controller of the motor is configured to transmit and receive data in a serial connection manner as described above, the transmission module 30 identifies each of the plurality of motors. It may also include an input means for setting the information.

That is, when the transmission module 30 detects that the control command is input from the input means and receives the control command, the transmission module 30 receives the identification information of the motor that is the target of the control command from the input means. That is, in the present invention, the control command may include identification information of the motor to be controlled together with control information regarding the rotation value of the motor.

The identification information of the motor can be set for each user by the input means for setting the identification information of each of the motors mentioned above. In another embodiment of the present invention, the input means for inputting a control command may be provided differently for each motor. In this case, the identification information about the input means may be fixed as the identification information about the motor.

For example, there may be separate input means for controlling zoom, focusing, and iris, and in this case, the input means to which the control command is input can be fixedly identified. In this case, the control command may include identification information of the motor to be controlled by automatically including identification information of the input means.

Alternatively, the motor to be controlled may be differently set for each input means according to the user, and this may be set by the input means for setting the identification information of the above-mentioned motor.

On the other hand, the transmission module 30 may include a database that can store the control command.

The database performs a function of storing a control command that has been input by a user according to a user's storage request input, and simultaneously loads a control command stored by a user's input mounted on the transmission module 30. Do this.

At this time, the database receives the identification information of the lens at the time of storing the control command, and stores the control command for each lens, so that when the user uses the control device in different cameras and lenses, the user can easily load the stored control command accordingly. Can be controlled.

Traditionally, when the motor is attached to the control wheel of a camera, when the motor is attached to another lens or the control wheel of another camera, a manual test process is performed to determine how the zoom, focusing and iris of the camera are controlled according to the control value. After confirming, the actual control work had to be carried out.

However, in the present invention, by storing the control command for each lens in the database, it can be loaded and used if necessary, so that the above test process is omitted, so that the control device can be used more easily and efficiently.

On the other hand, when the motor is installed in the focusing control wheel to control the focusing of the lens, the numerical value in the unit of the distance (ft or m) displayed on the camera lens should be displayed on the input means of the transmission module in the same way as the lens. However, in order to control different lenses, the specifications are different for each lens, so it is necessary to manually mark each time a lens is changed.

In order to solve this problem, when the transmission module 30 of the present invention receives an input for storing control numerical information relating to focusing on a new lens from an input means, focusing among the motors of the motor unit 20 is performed. By rotating the motor installed in the control wheel to control, and transmits a control command for detecting the minimum value point and the maximum value point of the control numerical point (that is, the distance) of the control wheel to control the focusing to the receiving module 40 In addition, the reception module 40 receives information regarding a minimum value point and a maximum value point among control value points of the control wheel that controls focusing.

Thereafter, the database receives and stores the control numerical information from the transmission module 30.

In this case, when controlling the focusing of various lenses, since only the control numerical information stored for each lens needs to be loaded and used, the focusing of the camera can be more easily controlled by eliminating the Hiroshi operation.

The control command may be stored for each lens, but may be stored for each time or for separate identification information according to the input of the input means.

The receiving module 40 includes an input port for wirelessly receiving a control command transmitted from the remote transmission module 30 and an output port for transmitting the control command to the motor unit 20.

The input port may be a wireless communication device and the output port may be a wired communication device. The receiving module 40 may be attached to the camera 10 separately, for example.

In the present invention, one input / output port may exist. In the output port, a wired communication network of a serial connection type is configured, and a controller of a motor may be connected to each intermediate node of a line.

The receiving module 40 receives a control command from the transmitting module 30 through an input port. In this case, as mentioned above, the control command may include identification information regarding at least one motor. The receiving module 40 converts it into a format that can be interpreted by the controller of the motor and transmits it through the output port.

That is, the information transmitted to the controller of each motor through the serial connection network of the motor unit 20 may include identification information of the motor together with a control command, that is, information on the control value of the motor.

Serially connected network means a network using a serial communication structure. A plurality of controllers are connected through one line, and control commands are matched with identification information of a motor to be controlled and transmitted to controllers of a plurality of motors connected through a serial communication structure. The controller of the motor stores its identification information. When the control command is received, the controller of the motor receives the control command whose identification information is matched to control the motor according to the control command, and the identification information of the motor does not match. If it is a control command, it will not be accepted.

Previously, to control each motor, control commands had to be transmitted through different output ports. Therefore, n ports were needed to control n motors. However, according to the present invention, since the identification information of the motor is included in the control command and the controller of the motor is connected through the serial communication structure, n motors can be controlled through one port.

On the other hand, since the control command can be stored in the database unit, the output port 42 of the receiving module 40 receives monitoring information, control value information, etc. at the time of control according to the control command from the

motors

21, 22, 23. Can be received. The monitoring information and the information about the controlled value are transmitted to the transmission module 30 through the input port 41 again, and the user can perform an input for checking and storing the information through the display unit provided in the transmission module 30. have.

As mentioned above, a serial communication structure is formed at the output port 42 of the receiving module 40, and a plurality of motors included in the motor unit 20 are connected to each note.

The input port 41 receives a control command as mentioned above, which is transmitted to the serial communication structure through the output port 42, and each motor of the motor unit 20 is connected to the identification information included in the control command. Therefore, the control command is controlled by receiving.
