Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand device for installing a video camera, which is suitable for recording a sound obtained by using an external microphone together with an image on a video tape.

[0002]

2. Description of the Related Art Recently, various types of video cameras have been put into practical use, such as a handy type video camera that can be operated with one hand, and a type of video camera that displays what is being photographed on a liquid crystal display. Usually, in the video camera, when the external microphone is not connected, the sound picked up by the built-in microphone is recorded together with the image, and when the external microphone is connected, the sound picked up by the external microphone is recorded. Is recorded together with the image.

Further, when it is almost unnecessary to move the video camera at the time of shooting, the video camera may be supported while being supported by a tripod or the like. For example, when taking a picture of a guest who is giving a speech on a special stage at a reception, set up a tripod in front of the special stage, fix the video camera on the top of the tripod, and use this special stage. A microphone stand is installed, the microphone is fixed to the upper end of the microphone stand, and this microphone is connected to the connection terminal of the external microphone of the video camera to record the sound together with the image.

[0004]

By the way, when a person making a speech as described above is photographed by a video camera fixed to a tripod, the person making the speech cannot adjust the photographing direction of the video camera. It's difficult, so you have to ask someone else to adjust the shooting direction of the video camera, but you have to readjust the shooting direction of the video camera every time a person with a different height speaks. It was very troublesome. An object of the present invention is to provide a stand device for installing a video camera, which allows a person as a subject to easily adjust the shooting direction.

[0005]

According to a first aspect of the present invention, there is provided a stand device for installing a video camera, which is a camera supporting unit installed on a floor surface in front of a subject, and which is a leg frame and a leg frame. A camera supporting means having a movably mounted mounting portion for fixing a video camera, and a camera supporting means extending from the camera supporting means to the vicinity of the subject toward one side of the subject, and one end of the camera directly or indirectly attached to the mounting portion. The other end, which is fixed and to which the external microphone of the video camera is attached, is provided with a microphone support rod arranged in the photographing area of the video camera. Here, it is a preferred embodiment that the microphone support rod is curved or bent so that only the other end side portion thereof enters the photographing area of the video camera.

[0006]

In the video camera installation stand device according to the present invention, the video camera is attached to the attachment portion of the camera support means installed on the floor surface in front of the subject, and the microphone support extending toward the subject is attached to the attachment portion. Since the rod is fixed directly or indirectly and the external microphone of the video camera is attached to the other end of the microphone support rod arranged in the shooting area of the video camera, the video camera is attached to the attachment portion and It will rotate with respect to the leg frame integrally with the microphone support rod.

For this reason, if the positional relationship between the external microphone and the shooting direction of the video camera is adjusted in advance so that the upper body or the whole body of the microphone user is shot by the video camera, height and standing will increase from the next time. Depending on the position, by adjusting the height position and the horizontal position of the external microphone, the shooting direction of the video camera is automatically adjusted via the microphone support rod, and the shooting direction of the video camera is manually adjusted each time. Even if the adjustment is not performed, the upper body or the whole body of the microphone user can be reliably photographed by the video camera.

When a video camera having a display for outputting a shot image is used as the video camera, the external microphone is rotated while visually observing the display to finely adjust the shooting direction of the video camera. It becomes possible to do.

If the microphone support rod is curved or bent so that only the other end side portion thereof enters the photographing area of the video camera, it is possible to prevent the microphone supporting rod from entering the photographing area as much as possible.
