Abstract

PURPOSE:To attain control a control item of an image transmission terminal device without any limitation of the range by using each control command for control start and control end corresponding to an operator input of an image receiving terminal device. CONSTITUTION:A video signal outputted from a television camera 5 at the image transmission terminal device B is amplified by an amplifier circuit 42 to a prescribed level, outputted to a video transmission line 8 via a line terminating circuit 41 and transmitted to the image receiving terminal device. On the other hand, the image receiving terminal device A receives the video signal transmitted via the video transmission line 8 from the image transmission terminal device B, a clamp circuit 12 reproduces the DC component, outputs it to an image reception monitor 2 and the video image picked up by the television camera is reproduced and displayed. An operating device interface circuit 13 of an image receiving terminal control section 1 supervises the depressing state of each control button of an operating device 3 at each control button, detects the timing of the depression start and depression end and inputs the result to a control command forming circuit 14. The control command forming circuit 14 forms the control command predetermined in response to each timing input and is transmitted to a control transmission line 9 via a line terminating circuit 11. The image transmission terminal device B decodes the control command fed from the image receiving terminal device A and performs the designated control.

ないという欠点がめった。(Prior Art) Conventionally, in a remote monitoring system that monitors the situation in a remote location, when controlling an image transmitting terminal, for example, controlling the zoom of a surveillance camera, the image receiving terminal displays a monitoring screen on a monitor. It was necessary to supply the power necessary for zoom control from the terminal. Furthermore, when the distance between the image sending terminal and the image receiving terminal is long to some extent, a method has been adopted in which a power supply device is installed on the image sending terminal side and this is controlled by contact information from the image receiving terminal. However, this method requires a cable for each control item to send contact information between the two terminals.
The drawback is that control over long distances is rarely possible due to the large number of signal lines.

動作させる。Control commands sent from the image receiving terminal (to) via the control transmission path 9 are sent to the line termination circuit 4 of the image transmitting terminal control section 4.
1 to the control command decoding circuit 43. The control command decoding circuit 43 decodes the input control commands and outputs drive information for the electric pan head or electric zoom lens corresponding to each control command for each control item. For example, if the llH" level of the drive information output terminal for each control item is set to drive and "L level is stopped, and the received control command is the electric platform operation right start command [36], the corresponding electric panhead Change the operation right drive information output terminal to wH level, then hold the ``Hl level'' until receiving the electric pan head right stop command [46], and change to ``L level'' when the stop command [46] is detected. let When control commands for other control items are received, the corresponding drive information output terminals are similarly controlled. These driving information are individually input to the pan head/zoom lens driving circuit 44 for each control item. Pan head/zoom lens drive circuit 4
4 drives the electric pan head 7 and the electric zoom lens 6 according to the drive information. For example, the control command decoding circuit 4
The zoom operation telephoto drive information output terminal 3 generates a drive voltage necessary for the telephoto operation of the electric zoom lens to operate the electric zoom lens 6 during the IIH level period. In the case of other control items, the corresponding electric pan head 7 or electric zoom lens 60 is operated by generating the driving voltage necessary for the corresponding operation.

こなうことができる。As is clear from the explanation below, when you start pressing the control button on the operating device of the image receiving terminal, a command to start the control is sent to the image transmitting terminal, and the desired control starts. When the control button is pressed down, the operation is stopped, so the image sending terminal can be freely controlled using the image receiving terminal.

When the control command is [24], a similar operation can be performed by setting the output levels of all drive information output terminals to -LI+.

能な送像端末を構成することができる。Furthermore, a control end command corresponding to each control item and a control end command common to all control items are assigned different commands, and the command decoding circuit 43 of the image sending terminal control section reads the decoded control command. In the case of a control command corresponding to each control item, the drive information output terminal corresponding to the control command is set to "L6," and if the decoded control command is a control command common to all control items, all By setting the drive information output terminal to L'', it can be set to either the receiving terminal that sends a control end command corresponding to each control/item, or the receiving terminal that sends a control command common to all control items. It is also possible to construct an image transmitting terminal that can also handle the following.

If there is a need to include a control that terminates the operation when the light-off button is pressed, the corresponding control item is Sends the start command when there is an input to press the end button, and sends the end command.
This can be easily achieved by ignoring the input to end the pressing of both buttons and not sending any commands.
