Abstract

PURPOSE:To easily move and control a television camera from the installing position of a monitor for monitoring. CONSTITUTION:A TV signal encoding circuit 2 to encode a video signal from the television camera 1, a decoder 3 to convert the video signal sent from this TV signal encoding circuit 2 into prescribed information and output it and the monitor 4 for monitoring to input and display output from this decoder 3 are provided, and the title TV monitoring device is characterized by providing besides the television camera 1 with a camera position control circuit 10 to control the movement of a photographing position by the television camera 1, and simultaneously, providing this camera position control circuit 10 with a photographing movement partial inhibition function to inhibit the movement to a predetermined position of the photographing position by the television camera 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV monitor,
In particular, the present invention relates to a TV monitoring device for monitoring the movement of a television camera in which photographing movement is limited to a certain degree.

[0002]

2. Description of the Related Art The photographing position of a camera is set by all the portions where the camera position can be seen from an operation panel and a camera whose movement position is prohibited by a signal from a camera transmission control circuit. ..

[0003]

In the above-mentioned conventional example, the photographing place is limited in the system, and if the photographing prohibition instruction remains after the monitoring, the prohibition can be released when the photographing can be performed again. Need to be kept.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a TV monitor apparatus which can improve the disadvantages of the conventional example, and in particular can easily control the movement of the TV camera from the position where the monitor for monitoring is installed. And

[0005]

According to the present invention, a TV signal encoding circuit for encoding a video signal from a television camera,
The television camera is provided with a decoder for converting the video signal sent from the TV signal encoding circuit into predetermined information and outputting the information, and a monitor for inputting and displaying the output from the decoder. A camera position control circuit for controlling the movement of the photographing position by the camera is also provided, and the camera position control circuit has a photographing movement part prohibition function for prohibiting the movement of the photographing position by the television camera to a predetermined position. , Etc. are adopted. This aims to achieve the above-mentioned object.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. The embodiment shown in FIG. 1 is a TV signal encoding circuit 2 for encoding a video signal S from a television camera 1.
A decoder 3 for converting the video signal A sent from the TV signal encoding circuit 2 into predetermined information and outputting the information, and a monitor 4 for inputting and displaying the output from the decoder 3.
It has and. The television camera 1 is provided with a camera position control circuit 10 for controlling the movement of the photographing position by the television camera 1. The camera position control circuit 10 includes a shooting movement part prohibition function for prohibiting the movement of the shooting position by the TV camera 1 to a predetermined position, and a shooting movement operation for canceling the effectiveness of the shooting movement part prohibition function as necessary. It has a flexible control function. At the same time, the remote control panel 11 for sending a flexible control activation command for activating the photographing movable control function of the camera position control circuit 10 to the camera position control circuit 10 is provided on the monitoring monitor 4 side. There is.

Reference numeral 20 indicates a photographing position signal transmission circuit interposed between the remote control panel 11 and the camera position control circuit 10. The photographing position signal transmission circuit 20 includes a camera position signal transmission circuit 20A and a camera position signal reception circuit 20B.
It is configured with and.

Further, FIG. 2 shows an example of the photographing prohibited range K set for the camera photographing range S.

[0009]

Since the present invention is constructed and functions as described above, the movement of the TV camera to the photographing prohibited area can be effectively restricted by the function of the camera position control circuit. Thus, it is possible to provide an excellent TV monitoring device that has not been available in the related art, in which it can be effectively controlled from the monitor monitor installation side.
