Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a television camera device.

[0002]

2. Description of the Related Art Conventionally, for example, a television camera centralized control unit (hereinafter abbreviated as SCU) has been used as a means for centralizing a plurality of television cameras (hereinafter abbreviated as cameras) at one place and performing adjustment by remote control. is there. (For example, the technique disclosed in Japanese Patent Publication No. 5-30345)

A conventional SCU is for adjusting a camera by switching and selecting a plurality of cameras arranged remotely at one place, and setting up (adjusting) all the cameras in the same state such as color matching between the cameras. It is convenient to do.

In this device, the cameras are selected one by one, and at the same time when the cameras are adjusted, the state of each camera is set in the SCU.
It is possible to switch and display each unit. An example of display according to this conventional technique is shown in FIG.

[0005]

In the above-mentioned prior art,
The adjustment status of each camera is switched and displayed on the SCU display on one screen. To compare whether the adjustment status of other cameras is the same, select each camera. It is necessary to confirm the adjustment status with the camera and perform the switching operation of the camera, and it is necessary to compare and confirm the contents of the status display items of each camera across a plurality of screens displayed for switching. Has the drawback of being complicated and error-prone.

It is an object of the present invention to eliminate these drawbacks and simultaneously display the adjustment states of a plurality of cameras on a display device to facilitate the operator's confirmation method.

[0007]

In order to achieve the above-mentioned object, the present invention provides the status display means 7 of FIG. 1 with the status of a plurality of cameras as shown in FIG. The display items are arranged in rows or columns and displayed at the same time.

The display means for displaying as shown in FIG. 2 may be provided not only in the SCU but also in a camera control unit (hereinafter referred to as CCU) forming a part of the camera.

[0009]

As a result, the status of all the cameras can be monitored at the same time without switching and selecting a plurality of cameras one by one, so that the labor of the operator of the television camera device can be saved and errors can be eliminated. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The overall construction of one embodiment of the present invention is shown in FIG.
Will be described. 8 is a television camera, 9 is an SCU
Is. The camera control signal switching circuit 1 is connected with the camera control signals 1a, 1b ... Of a plurality of cameras. The control signal 12 of the camera selected by the camera selection signal 11 is connected to the camera control signal input / output circuit 2 to enable control of the selected camera.

The camera selection signal 11 is output from the ON / OFF signal output circuit 3. The camera selection is performed by the camera selection means 5, and the camera adjustment is performed by the camera adjustment means 6. The status during adjustment is displayed on the status display means 7. The CPU 4 controls each block. Since these details are well known in the art and can be easily understood, description thereof will be omitted.

Next, a method of displaying the camera adjustment state of the present invention will be described with reference to FIG. As shown in FIG. 2, the status display means 7 has a camera No. which identifies a plurality of cameras by turning on the status display selection switch 5a. (Camera number), camera status display items, and information are displayed simultaneously in rows and columns. This allows the differences in the states between the cameras to be compared at a glance.

At this time, the standard state and the non-standard state defined as shown in FIG. 2 are distinguished, and for example, ND = 2 (indicating that the second filter for limiting the light quantity is included). It is conceivable to change the non-standard state of CC or C = C (indicating that the C-th color temperature correction filter is included) to an easy-to-understand display such as black and white reverse display.

If the number of cameras or the number of status display items exceeds the number that can be displayed on the screen of the status display means 7, the desired camera No. The camera status of can be displayed. As the status display means 7, various kinds such as an LCD display panel, an EL display panel, a CRT display device, etc. can be considered.

Further, by pressing the individual camera selection switch 5b in the camera selection means 5, the display can be switched to the conventional display for each camera as shown in FIG. 3, and the adjustment and display for each camera can be restored. it can.

FIG. 4 shows a flowchart of the camera status display of the present invention. When the status display selection switch 5a is ON, the camera No. The process of selecting the cameras in order from the first camera, reading the states of the cameras from the cameras, and displaying the states on the display of the state display means 7 is the camera No. 1. Repeat until n cameras. When the status display selection switch 5a is OFF, the operation is the same as the conventional operation.

The display means according to the present invention can have the same function not only in the SCU but also in the CCU.

[0018]

According to the present invention, it is possible to monitor the status of a plurality of cameras at the same time without switching and selecting a plurality of cameras one by one, thereby saving the labor of the operator of the television camera device. You can
