Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lens adjusting apparatus for use with a camera, such as a DSLR,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lens adjusting apparatus for use with a camera equipped with a zoom lens, such as a DSLR camera, as a broadcasting camera, and more particularly, To a lens control device that provides a function of remotely controlling the lens.

The broadcasting camera shows what the viewer wants to see in place of the viewer's eyes and shows the images selected by the director. That is, it transmits the selected images to the viewer.

Because of this role, broadcasting cameras are essential and central equipment in the production of TV programs. All of the equipment required for production depends on the characteristics of the broadcasting camera, and also depends on the quality and size of the program and the broadcasting camera used.

Specifically, a broadcast camera is mainly used in a studio designed for broadcasting. This broadcast camera is as diverse and stable as that used in the studio, and is mainly used for recording or live broadcasting. However, there are big and heavy drawbacks, and when moving, you have to travel through a tripod that includes a pedestal wheel.

In addition, the broadcasting camera includes a camera head including a lens, an internal optical device, and a viewfinder, and a control device, a recorder, and a power supply device capable of controlling the main functions of the camera.

In addition, the broadcasting camera is provided with an internal communication system such as a tally light or an intercom. Since a plurality of broadcast cameras simultaneously record a general broadcasting screen, the recording of the broadcasting screen is a screen captured by one of the cameras. Therefore, the cameraman needs to check which camera is used to record the screen. At this time, the apparatus used is tally light.

In other words, Tally Light is a lamp in front of each camera, and when it lights up, it shows that the screen that the camera is holding is recording or broadcasting. Moreover, Tally Light helps performers align their gaze or help other cameramans prepare for the next screen.

On the other hand, the intercom is a device by which the director and other production staffs can communicate with each other while broadcasting. The director can tell the cameraman how to move several cameras among the multiple cameras through this intercom.

More specifically, such a broadcasting camera can be generally divided into a standard camera and a handy camera (also referred to as an ENG camera or an EFP camera).

The standard camera has a disadvantage that it can be used only at a place where the same conditions as the studio or the studio are provided, rather than functioning as a camera, to catch a side of a subject or to catch an electronic signal of an image medium.

The Eelectronic Field Production (EFP) camera has a function similar to that of an ENG camera, but it plays a role of a studio camera which has better portability than an independent image operation. It does not have a recording device, The cable connected to the unit controls other functions in a separate location, such as the secondary control room.

Generally, when shooting sports broadcasts or studio broadcasts or when recording a set of dramas, the EFP camera captures images.

Since the EFP camera does not have its own recording function, it requires a lot of manpower, has low mobility, and is relatively expensive compared to an ENG camera, so that it is difficult to use the EFP camera other than a broadcasting company.

Meanwhile, the ENG (Electronic Field Production) camera is designed to be portable so that a cameraman can carry it, and means a camera capable of recording an image in a separate small-sized recording device or a recorder built in the camera.

These ENG cameras have the power to respond quickly to events, the maneuverability to capture the whole process of events, and flexibility in equipment and personnel. In addition, ENG cameras are compact and lightweight, allowing them to quickly approach events, situations, and people faster than any other equipment, and shoot on camera shoulders instead of tripods or studio pedestals. Angles can be captured immediately. In addition, it has the advantage of being able to respond immediately to the scene situation and to be able to shoot easily even in extreme conditions.

As described above, ENG cameras are efficient in outdoor production of news, documentary, and drama because they have easy mobility and independent working ability.

However, since it mainly features outdoor shooting and recording with a minimum number of people in the outdoors, it can not use the production adjustment function as in the studio, so it is difficult to expect high quality picture and audio.

In order to solve the above-described problems, the present applicant has developed Korean Patent No. 10-1286156 entitled " ENG camera use conversion system ".

However, even an ENG camera to which such a conversion system is applied has a disadvantage in that it is relatively expensive to be purchased by a small-sized broadcasting station or a single-person broadcasting producer.

Accordingly, in recent years, a DSLR camera can be used as a broadcasting camera, and development of a technology for remotely controlling the camera lens is required.

Korean Patent Publication No. 10-2000-0058442 (published on October 10, 2000) Korean Registered Patent No. 10-1553928 (Announced 2015.09.17) Korean Patent Publication No. 10-2011-0113567 (published on October 17, 2011) Korean Patent Publication No. 10-2010-0007220 (published on Jan. 22, 2010)

Accordingly, it is an object of the present invention to provide a function of a broadcasting camera so that a camera including a lens having a video photographing performance can be used as a broadcasting camera according to a user's selection, and can easily zoom, focus, And to provide an adjustable lens control device.

In order to accomplish the object of the present invention, in one embodiment of the present invention, there is provided a zoom lens in which a camera provided with a zoom lens is seated and provided with a space to be fixed, and a ring gear And a second motor having a rotation shaft coupled to the spur gear to provide a rotational force to the spur gear, and a second motor electrically connected to the second motor, And a zoom controller connected to the camera adapter and receiving a control signal for the zoom controller to transmit the control signal to the camera adapter.

According to the present invention, a camera equipped with a room lens can be operated as a broadcasting camera. In particular, the present invention can relay, store, and transmit broadcast signals that can support up to UHD (Ultra High Density), 4K (4096x2160), and 8K (8192x4320) resolutions using a camera equipped with a zoom lens.

Further, the present invention can precisely adjust the zoom and focus of the zoom lens remotely even if the user does not directly adjust the zoom lens through the hand.

In addition, since the broadcasting equipment used in the broadcasting system maintains an expensive price, the broadcasting service can not meet the expectation of the consumers in addition to some broadcasting companies. However, when the lens controlling apparatus of the present invention is used, It is possible to reduce the manufacturing cost and to produce a high-quality program with a small cost. In addition, the initial cost required for the construction of the broadcasting system can be lowered, thereby making it possible to lower the entry threshold of the broadcasting industry.
