USE CONVERTING SYSTEM WITH ELECTRONIC NEWS GATHERING CAMERA}

The present invention relates to a conversion system for ENG cameras that can utilize the ENG camera as an EFP camera, and more particularly, to maximize the usability of the ENG camera by enabling the use of the ENG camera different from the EFP camera as an EFP camera A conversion system for an ENG camera.

The TV camera shows what the viewer wants to see and shows the images the director chooses instead of the viewer's eyes. In other words, it plays the role of delivering the video selected by the director to the viewer.

Because of this role, TV cameras are essential and central equipment in TV program production. The equipment required for production is all affected by the characteristics of the TV camera, and also depends on the quality and scale of the program and which TV camera is used.

Specifically, TV cameras are mainly used in studios designed for broadcasting. This TV camera is as versatile and stable as it is used in the studio and is mainly used for recording and live broadcasting. However, there is a big and heavy disadvantage, when moving through a wheel called a pedestal.

In addition, the TV camera includes a controller, a recorder, a power supply, and the like, in addition to a camera head including a lens, an internal optical device, and a viewfinder.

In addition, the TV camera is provided with an internal communication system such as tally light or intercom. In general, the broadcast screen is recorded by several TV cameras at the same time, but since the recording is taken by one of the cameras, the cameraman needs to check which camera is recording the screen. At this time, the apparatus used is thalilite.

In other words, a tally light is a lamp in front of each camera that, when lit, indicates that the screen held by that camera is recording or broadcasting. Moreover, tallylights help performers orient themselves or prepare other cameramen for the next shot.

On the other hand, the intercom is a mechanism that the director and other production staff can communicate with each other during the broadcast. The intercom can tell the cameraman how the camera out of several cameras should be moved.

More specifically, such a TV camera may be generally classified into a standard camera and a handy camera (aka ENG camera or EFP camera).

The standard camera plays a role of catching the side of the subject or catching the electronic signal of the image medium, rather than functioning as a camera, and can be used only in a studio or a place equipped with the same conditions as the studio.

On the other hand, the ENG (Electronic Field Production) camera is designed to be portable so that the cameraman can carry means a camera capable of recording an image in a separate compact recorder or a recorder built in the camera.

These ENG cameras have the quickness to respond quickly to events, the maneuverability to capture the entire process, and the flexibility of equipment and personnel. In addition, ENG cameras are compact and lightweight, allowing you to quickly shoot and access events, situations and people faster than any other equipment, and place them on cameraman's shoulders instead of tripods or studio pedestals. The angle can be captured immediately. It also has the advantage of being able to respond immediately to on-site situations and to easily shoot even in extreme conditions.

In this way, ENG cameras are easy to use in the production of news, documentaries, and dramas because they have easy mobility and independent working ability.

However, it is difficult to expect high-quality screen and audio because it is not possible to use the production adjustment function as in the studio because it is characterized by instant shooting and recording with a minimum number of people in the outdoors.

In addition, the EFP (Eelectronic Field Production) camera has a function similar to that of the ENG camera in terms of adjustment of the camera, but it is a camera that acts as a mobile studio camera that is more mobile than an independent video work. Usually other functions are coordinated in a separate location, such as a coordination room, via a cable connected to the unit.

In general, a video is captured by the EFP camera when playing sports or studio broadcasting or recording a set of a drama.

Since the EFP camera does not have a recording function of its own, a large number of manpower is required, mobility is low, and it is difficult to use other than a broadcaster because it is relatively expensive than an ENG camera.

Accordingly, there is a demand for the development of a technology that enables the use of an ENG camera as an EFP camera so as to take advantage of both the ENG camera and the EFP camera.

Japanese Patent Laid-Open No. 11-284900 (announced on October 15, 1999) Republic of Korea Patent No. 10-0697965 (announced on March 23, 2007)

Accordingly, it is an object of the present invention to provide a conversion system for an ENG camera, which gives an ENG camera the function of an EFP camera so that an existing ENG camera can be used as an EFP camera according to a user's selection.

By using the conversion system for the ENG camera according to the present invention, the ENG camera can be operated as an EFP camera, it is possible to maximize the utilization of the ENG camera.

And because the broadcasting equipment used in the broadcasting system maintains an expensive price range, although the broadcasting service is not meeting the expectations of consumers other than some broadcasting companies, using the system of the present invention can reduce the production cost for the program This makes it possible to produce quality programs at a small cost. In addition, it is possible to lower the initial cost required for the construction of the broadcast system can lower the entry threshold of the broadcast industry.

Conventionally, different manufacturers have different standard specifications, and therefore different manufacturers may not use ENG cameras and broadcasting operating equipments together, but using the system according to the present invention enables manufacturers to use different ENG cameras and broadcasting operating equipments together.
