Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video system suitable for news gathering, etc., and a carrying case for transporting this video system.

[Prior Art] When reporting news, a camera-integrated video tape recorder (hereinafter referred to as a video camera) is brought to the site to record the news, and the recorded tape is edited at the broadcasting station. However, such news gathering generally requires at least two people: a cameraman who operates a video camera and takes pictures, and an analancer who conducts interviews, etc., and therefore has the drawback of lacking mobility.

By the way, Japanese Patent Laid-Open No. 1-264080 proposes an electric camera head that can be operated remotely, and a video system using this electric camera head, that is, a video camera is supported on a tripod via the electric camera head. It is believed that the above drawbacks can be solved by constructing a video system. In this video system (for convenience, we will refer to it as a conventional video system), the person being photographed, the analancer, can control the direction of the video camera by remote control of the motorized platform, allowing him to change the direction of the video camera to the desired direction. It is also possible to conduct interviews while taking photographs.

[Problems to be Solved by the Invention] However, in the conventional video system described above, the anallancer must remotely control the direction of the video camera while broadcasting live broadcasts, so the direction of the video camera may not match the desired direction. There are problems in that it is not possible to confirm whether or not they match, and it is not possible to recognize the screen shot by the video camera, making it impossible to provide an explanation based on the screen shot.

Furthermore, since the above-mentioned conventional video system consists of a large number of components such as a video camera, a pan head, and a tripod, it is difficult to transport all the components by one person. There is also the problem that transporters are essential, making it difficult to conduct interviews alone.

This invention was made in view of the above problems, and is the first invention.
The object of the invention is to provide a video system that allows a person to be photographed to recognize the photographed screen, and the object of the second invention is to provide a carrying case that allows one person to easily transport the video system. .

[Means for Solving the Problems] In order to solve the above problems, a video system according to the first invention includes a video camera, a tripod to which the video camera is attached, and an intermediary between the tripod and the video camera. The video camera is equipped with an electric pan head that changes the direction of the video camera in response to an operation command from a remote controller, and a monitor that is installed on a tripod so that the person to be photographed can view it and displays the photographed screen of the video camera.

[Operations] The video system of the first invention allows the anallancer to remotely control the electric pan head using a remote controller and change the direction of the video camera, so even a single anallancer can conduct filming and reporting. . In addition, since the anallancer who is the subject of the photograph can also recognize the shooting screen on the monitor, the desired subject can be accurately photographed.
It is possible to provide explanations based on the shooting screen.

In particular, in the video system of the present invention, by configuring the monitor to be placed at approximately the same height as the video camera, the monitor can be easily seen even when the subject's eyes are directed toward the video camera. This allows you to obtain a shot screen where the person is looking directly at the video camera.

Furthermore, the video system of the present invention is configured in such a manner that the monitor is also supported by an electric pan head and can be rotated independently from the video camera, so that the monitor can be used as a subject regardless of the orientation of the video camera. The shooting screen can be recognized more easily. In this embodiment, the other of the video cameras or monitors is supported via the second electric trip head on top of one of the video cameras or monitors supported via the first electric trip head, and the second By configuring the electric pan head to operate in the opposite direction to the first electric pan head, one side of the video camera or monitor can be moved without changing the orientation of the other by simply activating the first electric pan head. The orientation can be changed, providing good usability.

Further, since the carrying case of the present invention can accommodate all the components of the video system, such as a video camera, a monitor, and cables, it can be carried by one person. The carrying case of the present invention is configured to accommodate a tripod, so that it can be carried with one hand.
