DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image adjusting device, and more particularly to an adjusting device for a television image signal used for live broadcasting or the like.

[0002]

2. Description of the Related Art Generally, in television broadcasting, an output image of an image adjusting device is broadcasted.
The broadcasted video must be switched seamlessly without interruption. Each video is required to be produced by synthesizing a single or a plurality of video materials and broadcast.

In order to fulfill these demands, a conventional video adjusting device is provided with a video mixing amplifier 7 (MK3) having a video signal output terminal 8 as shown in FIG. Therefore, the video signal to be output was switched. The amplifier 7 alone usually has two or more video input terminals, and has a function of not only directly selecting and transmitting a simple material video, but also performing a simple effect of synthesizing a plurality of videos.

With respect to the material video to be input to the amplifier 7, a video mixing amplifier 5 (MK 1) is selected as a position that can be selected by the amplifier 7 so that a screen in which a plurality of material videos are synthesized in advance can be prepared and transmitted. And a video mixing amplifier 6 (MK2). Then, while one of the amplifiers prepares a video to be transmitted next, the amplifier 7 selects the other (a ready amplifier) or direct video material and transmits the selected video. Are alternately applied for the preparation of the next screen, and are switched and transmitted, so that the program proceeds smoothly. Reference numeral 4 denotes a video signal input terminal.

A control line between each operation panel and the amplifier not only transmits the operation information of the operator to the amplifier, but also controls the control state of the amplifier by the operation of the operator by turning on a lamp or displaying characters. It is also used to transmit information for display on the panel.

However, as described above, in the conventional video adjusting apparatus, the two video mixing amplifiers are alternately applied for the preparation of the next screen, switched, and selected and transmitted. The panel to be operated changes every time. This not only complicates the operation, but also involves the risk of erroneous operation that always interferes with the video being sent, and has the disadvantage that tension is imposed on parts other than the original video production. Was.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide an image adjusting apparatus which can reduce the operational complexity of an operator.

[0008]

An image adjusting apparatus according to the present invention comprises a first or second image mixing amplifier for creating a screen in response to a command from the first or second operation panel, and a command from the third operation panel. a third video mixing amplifier for alternatively sending the output of the first and second video mixing amplifier in response to said first
1 of a first changeover switch which allowed to enter the command or the first or second operation panel <br/> et al video mixing amplifier, wherein
A second changeover switch for inputting a command from the first or second operation panel to the second video mixing amplifier.
And the third video mixing amplifier is connected to the first switching switch.
Controlling the switch and the second changeover switch,
The third image of the first and second image mixing amplifiers;
The video mixing amplifier not selected in the mixing amplifier
1 to input a command from the operation panel.
The third video mixing amplifier of the second video mixing amplifier;
The second operation parameter is applied to the video mixing amplifier selected in the amplifier.
Characterized Rukoto allowed inputs an instruction from the panel.

[0009]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of an image adjusting apparatus according to the present invention, and the same parts as those in FIG.

In the figure, unlike the conventional apparatus, a mixed amplifier for signal transmission and a next screen preparation (preparation) are different from the conventional apparatus.
Switching switches 91 and 92 are provided so that the operation panel 1 is always used for creating the next screen and the operation panel 2 is always used for signal transmission even if the mixed amplifier is switched by operating the operation panel 3. .

[0012] Now, select the amplifier 6 by an amplifier 7, it is assumed that sends the image that is produced by increasing <br/> width unit 6,
The switch 92 selects the output of the operation panel 1 to
It is assumed that the switch 91 selects the output of the operation panel 2 and is connected to the amplifier 6.

Here, the operator operates the operation panel 1 to produce a video to be transmitted next. As a result, the amplifier 5 operates, and a video according to the operation is created.
Is displayed on the operation panel 1 .

Subsequently, the operator operates the panel 3 to
Switching is performed to transmit the video of the amplifier 5 just prepared. By this operation, the amplifier 7 operates, and the output video of the amplifier 5 is transmitted (hereinafter, referred to as “up to OA (on air)”), and the switches 91 and 92 are switched.

According to this, the display of the control state of the amplifier 5 which has been raised to OA is displayed on the operation panel 2, and instead, the state of the amplifier 6 which has been OA is displayed on the operation panel 1. Will be displayed.

Needless to say, the amplifier 5 is currently in OA.
The preparation for the next screen is a state to be performed for the amplifier 6.

It should be noted here that the amplifier for which the next screen is to be prepared is always connected to the operation panel 1 even though the OA amplifier is switched. In addition,
The amplifier in the OA is always connected to the operation panel 2.

As a result, the operator, as before,
By operating the operation panel 1, a preparation operation for a video to be transmitted next can be performed on the amplifier 6.

Subsequently, when the operation panel 3 is operated, the amplifier 7 operates and the amplifier 6 rises to OA again.
Switches 91 and 92 are switched. As a result, the operation panel 1 and the amplifier 5 are connected and used for the next screen setting, and the amplifier 6 is connected to the operation panel 2 and returned to the state of being used for OA screen control, as described above. .

By repeating the above operations, the operator proceeds to produce a program.

The control signals to the changeover switches 91 and 92 are sent from the amplifier 7 and are signals according to the changeover command from the operation panel 3.

[0022]

As described above, according to the present invention, 3
The functions of the two operation panels can be fixed for the next screen, for the transmission screen, and for switching, respectively, which can improve the complexity of the operator's operation and eliminate unnecessary tension for video adjustment, This has the effect of eliminating the occurrence of erroneous operations due to the change of the panel to be operated.
