Abstract

PURPOSE:To make the video to pick up by the operator of a video camera by providing a display which reproduces picture signals picked up by the camera and operating means which performs remote-control operation to the video camera. CONSTITUTION:When an operator carries a remote-control transmitter A by a grip 2 and presses a picture recording button 35, a video camera is set to the picture recording state. When the video camera starts to pick up images, the picked-up pictures are displayed on a liquid crystal display 1. When the operator operates a picture recording button 35 after the operator decides an appropriate camera angle by freely performing remote-control operations to the camera angle and zoom lens, etc., by operating each button while the operator watches the picture on the display 1, the picture on the display 1 is recorded on a tape in a picture recording section. At this time, the operator can move within the reach of a signal transmitting cord. Therefore, the picture of the operator can also be taken.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control transmitter that can image the operator of a video camera.

[Background of the invention]

Conventionally, in order to photograph and record a video of a camera operator himself/herself with a video camera, the camera operator must set the camera at an appropriate position and come within the photographable range of the camera.

[Problem to be solved by the invention]

However, the problem with the recording method described above is that it is not possible to optimally adjust the direction of the video camera's lens (hereinafter referred to as the camera angle) or operate the zoom up/down, and the special features of the video camera are not fully utilized. there were.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a remote control transmitter that allows an operator to take a video image of himself while performing various operations on a video camera.

[Means to solve the problem]

To this end, the remote control transmitter of the present invention is configured to include a display for reproducing image signals captured by a video camera, and operating means for remotely operating the video camera.

〔Example〕

A remote control transmitter for a video camera according to an embodiment of the present invention will be described below. FIG. 1 is a front view of the remote control transmitter A. In the figure, 1 is a liquid crystal display provided above the remote control transmitter A, 2 is a handle provided below the liquid crystal display 1, and an operation unit 3 is formed on the front surface of the handle 2. has been done.

The operation unit 3 includes a video camera B (
Various operation buttons, setting buttons, etc. for remote control (to be described later) are arranged. That is, 31 is a button for rewinding the tape of the recording section, 32 is a button for playback, 33 is a button for fast forwarding the tape, 34 is a button for pausing, 35 is a button for recording, and 36 is a button for stopping.

Further, 37 is a group of camera angle rotation buttons, including up/down swing buttons 37a, 37b and left/right swing buttons 37c, 37.
It is composed of d, etc. 38 is a group of zoom setting buttons,
It consists of an enlargement button 38a, a reduction button 38a, etc.

4 is a signal transmission cord connected to the lower end of the handle part 2;
The other end is connected to the video camera B, and a control signal generated by operating the operation section 3 is transmitted to the video camera B. Further, an image signal captured by the video camera is transmitted to the remote control transmitter A via the cord 4, and the image is displayed on the display 1.

FIG. 3 is a diagram showing a video camera B with an integrated recording/playback unit controlled by a remote control transmitter A. This camera B is attached to an angle control device mounted on the upper part of leg C. This angle control device receives the angle control signal generated by operating the button group 37 sent via the code 4 from the video camera B via the code 5, and controls the forward and reverse directions of the motor provided inside. Through rotation control and rotation speed control, the angle of the camera B is changed by extending/contracting/rotating the shaft 6 vertically and horizontally.

Now, when recording a video using the remote control transmitter A of this example, first, the video camera B is installed at an appropriate position and in an appropriate orientation. Next, hold the handle part 2 and send the remote control @
When the user presses the record button 35 while carrying A, the control signal generated thereby is transmitted to the video camera and the video camera is set to a recording state. When the video camera starts capturing images, the captured image is displayed on the LCD display 1.
will be displayed. Hereinafter, by operating each button on the operation unit 3 while looking at the image on the display 1, you can freely remotely control the camera angle, zoom, etc. recorded on tape.

At this time, since the operator can move within the reach of the signal transmission cord 4, the operator can perform operations at any position within that range, and can also enter the recording range himself. becomes.

Furthermore, the camera can be installed and operated near the ceiling, on the floor, or on a wall, and recording from special angles, which was difficult with conventional cameras, is also possible.

In the above example, the signal is transmitted from the remote control transmitter A to the video camera B via the code 4, but instead of the code 4, the remote control transmitter A is provided with an infrared signal transmitter, and the signal is transmitted from the remote control transmitter A to the video camera B. is provided with a receiving section for receiving the infrared signal, and the control signal generated by the operating section 3 is transmitted from the transmitting section to the receiving section of the video camera using the infrared signal as a carrier to operate the video camera. You can also do it.

In this case, in order to be cordless, the video camera B is provided with a device that wirelessly transmits the image signal captured by the video camera, and the remote control transmitter A is provided with a device that receives the wireless signal and displays it on the liquid crystal display 1. It is necessary to provide

By operating other buttons on the operation section 3 of the remote control transmitter A, operations such as stopping recording, playing back, and fast forwarding can also be performed.

〔Effect of the invention〕

As described above, according to the present invention, since the video camera can be controlled remotely, it becomes possible to take a video image of the operator himself while operating the video camera.
