Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a television camera and a television camera operating device for arbitrarily selecting a field of view of the television camera and displaying an image captured by the television camera on a television monitor. .

[Conventional technology]

FIG. 3 is a block connection diagram showing a conventional television camera operating device disclosed in, for example, Japanese Patent Application Laid-Open No. 52-124813. In the figure, 11 to 1n are television cameras equipped with an electric zoom lens and an electric turntable. , 21 are the TV cameras 11 to 1n
Is a video switching device for switching the video signal of, and the output signal of the video switching device 21 is displayed on the television monitor 31. Reference numeral 41 is a preset visual field controller capable of moving the visual fields of the television cameras 11 to 1n to a predetermined position and stopping them, 52 is a television camera operating device, and this television camera operating device 52
Select switch for camera selection as shown in Fig. 4.
53 and a selection switch 54 for selecting a television field of view are provided.

The block connection diagram of FIG. 3 is a simplified version of the block connection diagram of the above publication.

 Next, the operation will be described.

When controlling the TV camera 11 to 1n, the TV camera operation unit
In 52, each selection switch 5 for camera selection and position selection
Select 3,54 respectively. That is, in FIG. 4, for example, the number 3, among the selection switches 53 for selecting the camera,
When the number 5 is selected from the selection switches 54 for selecting the television field of view, the television camera operator 52 outputs a camera selection signal and a field of view selection signal, which are input to the image switch 21 and the preset field of view controller 41. Video switcher 21
Then, the video signal of the TV camera 13 of number 3 is selected and displayed on the TV monitor 31. At the same time, preset visual field controller
In 41, the preset field-of-view position data corresponding to the number 5 of the TV camera 13 is selected so that the zoom position data of the electric zoom lens and the current position data from the electric rotary base coincide with this data value. To control the electric zoom lens and the electric turntable to stop when they match. Thereby, a predetermined visual field can be obtained.

[Problems to be solved by the invention]

Since the conventional TV camera operating device is configured as described above, when the TV camera 11 to 1n visual field positions are selected and operated, since the selection switches 53 and 54 display symbols such as numbers, the desired visual field is displayed. When selecting, select switch 5
There is a problem that quick operation cannot be performed because a correspondence table of 3,54 and the visual field position is required, and this is selected by collating.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a television camera and a television camera operating device capable of selecting a desired field of view quickly and intuitively.

[Means for solving problems]

A television camera operating device according to the present invention divides a plurality of television cameras and field-of-view views of the areas that can be imaged by the plurality of television cameras into areas that can be imaged by each television camera, and sets a large section. The large section is further divided into a plurality of sections according to the viewing range of each TV camera, and the small sections are set, and a plurality of selection switches provided corresponding to each of these small sections are provided, and a single operation of these selection switches is performed. A television camera operating means for outputting a camera selection signal and a field-of-view selection signal, a field-of-view control means for controlling the field of view of the camera based on the field-of-view selection signal output from the television camera operating means, and an output from the television camera operating means. Control means for operating the television camera selected based on the selected camera selection signal, and these visual field control means and camera control means In more selected operation field of view range of the television camera, in which a television monitor for displaying an enlarged captured image.

[Action]

In the television camera operating device according to the present invention, the camera and the field of view can be simultaneously selected by a single operation of the television camera operating device, so that the image of the target portion of the subject can be quickly and easily obtained on the television camera. be able to.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 51 is a data storage device which outputs a preset camera selection signal and visual field selection signal by one operation input, and 52 is a television camera operation device. In addition, the same components as those shown in FIG. 3 are denoted by the same reference numerals, and duplicate description thereof will be omitted.

FIG. 2 shows a group of selection switches 50 provided on the television camera operating device 52. Here, a square area surrounded by a broken line is one selection switch 50, and is also a one-dot chain line, for example, K1 to K4. Each of the four divided regions shows an image pickup region which one TV camera is in charge of. Further, the drawing drawn by a solid line shows each of the TV cameras 11 to 1n (for example, 4
(A table) shows a view of a range that can be imaged. This example shows a dam levee.

In the television camera operating device 52 shown in FIG. 2, the location of the selection switch 50 surrounded by a broken line can be indicated by the coordinates of the x axis and the y axis. Then, a camera number (for example, a camera number in charge of each of the areas K1 to K4) and a field of view number (for example, 1a to 8f) are preset in the data storage device 51 corresponding to each one of the selection switches 50. . Further, the correspondence between the view D and the selection switch 50 is selected by selecting the selection switch 50, and the region surrounded by the broken line of the view D superimposed on the upper surface thereof is imaged on the entire screen of the television monitor 31. To arrange.

The view diagram D is a configuration diagram, a layout diagram, etc. of the range that can be imaged by the television cameras 11 to 1n, and the data of the view diagram D in the predetermined range of the image is input to the data storage unit 51 in advance. It may be the one you have set up.

 Next, the operation will be described.

As shown in FIG. 2, when the field of view D is handled by the TV cameras corresponding to the areas K1 to K4, first, the operator selects the selection switch 50 on the TV monitor 31 at a desired position.
Select one of them. For example, when the switch whose location is 3e is selected, the operation signal corresponding to the selection switch 50 is output from the television camera operating device 52 and input to the data storage device 51. In response to this operation signal, the data storage unit 51 outputs a camera selection signal corresponding to the preset camera number and a visual field selection signal corresponding to the visual field number.

Therefore, based on the camera selection signal, by selecting a video of a predetermined TV camera by the video switch 21 and displaying it on the TV monitor 31, based on the view selection signal, the preset view controller 41, The visual field data is selected, and the zoom amount and focus amount of the electric zoom lens and the rotation amount of the electric rotary base are automatically adjusted according to the visual field data. The image thus obtained on the television monitor 31 is an enlarged image of the subject in the area of the selected location.

The above-described embodiment can be applied to both the moving image transmission system and the still image transmission system as the video transmission system, and has the same effect.

[Effect of device]

As described above, according to the present invention, since the field of view is superimposed on the upper surface of the selection switch for selecting the TV camera, it is possible to select the TV camera without using the correspondence table by a single operation of the selection switch. The field of view can be selected at the same time, and the image of the target region of the subject can be obtained quickly and easily on the television monitor.
