Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a general-

The present invention relates to a general-purpose camera controller capable of remotely controlling a non-broadcast camera, and more particularly, to a non-broadcast camera that provides compatibility with a non-broadcast camera regardless of a manufacturer and an operating system, To a general-purpose camera controller.

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 disadvantages, and when moving, you have to move through the 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.

Such a broadcasting camera is generally classified 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 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 on a separate small picture recorder or a picture 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 addition, Eelectronic Field Production (EFP) cameras have functions similar to those of ENG cameras, but they do not have recording equipment, Usually, other functions are adjusted in a separate place, such as a minor control room, via a cable connected to the unit.

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.

In recent years, the functions of camera modules used in non-broadcast cameras such as DSLR cameras, mirrorless cameras, and smart phones have advanced and are close to the level at which broadcast images can be taken. Therefore, technologies utilizing non-broadcast cameras as broadcast cameras have been developed .

In particular, application conversion systems for cameras that use DSLR cameras, mirrorless cameras, and smart phones as the aforementioned handy cameras are being developed.

However, existing broadcasting cameras control setting values such as white balance, contrast, brightness, and iris through a camera control unit (CCU) installed in an automobile or the like , There is a problem that the camera controllers are incompatible with each other by the manufacturer of the broadcasting camera.

In addition, the non-broadcast camera has a completely different operating system from the broadcast camera, and since each manufacturer has its own data value, the conventional camera controller can not be used to control the setting value of the non-broadcast camera.

In addition, even if a camera controller that can be used for a non-broadcast camera is developed, such a camera controller can be limited to only non-broadcast cameras of the same manufacturer, so that various non-broadcast cameras can not be used for broadcasting cameras without limitation .

Korean Patent Publication No. 10-2008-0032941 (published on April 16, 2008) Korean Registered Patent No. 10-1295895 (Announced 2013.08.19) Korean Patent Laid-Open No. 10-2009-0126705 (published on December 9, 2009) Korean Patent Publication No. 10-1992-0022834 (published Dec. 19, 1992)

Therefore, it is an object of the present invention to provide a non-broadcast camera in which a director can control setting values such as white balance, contrast, brightness, And a camera controller for controlling the camera.

In order to achieve the above object, according to an embodiment of the present invention, there is provided a communication system including a communication unit connected to a camera controller and a camera for non-broadcasting, a storage unit storing brand control signals matched to standard control signals, A control signal converting unit for converting the standard control signal into a brand control signal through the storage unit and a standard control signal transmitted to the communication unit from the camera controller to the control signal converting unit And a control unit for transmitting the brand control signal converted by the control signal conversion unit to the non-broadcast camera through the communication unit.

According to the present invention, a non-broadcast camera having a high-quality moving picture photographing function can be operated as a broadcast camera.

In addition, the present invention provides compatibility with non-broadcasting cameras having different manufacturers and operating OSs, so that it is possible to use various non-broadcasting cameras as a broadcasting camera without limitation, and a setting value for non-broadcasting cameras of various brands can be controlled by a director remotely .

In addition, the present invention relays, stores, and transmits broadcast signals that can support up to UHD (Ultra High Density), 4K (4096x2160), and 8K (8192x4320) resolutions using a smartphone, a DSLR camera, a mirrorless camera, .

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 other than the large broadcasting companies, but the present invention can reduce the production cost for the broadcasting program So that it is possible to produce a high quality broadcast program even at a small cost.
