FIG. 2 is a block diagram showing the configuration of the electronic script device.

As shown in FIG. 1, the electronic script device mainly includes an operation unit 30 and a video selector 32. The video selector 32 is detachably attached to the camera body 14 as shown in FIG. As shown in FIG. 2, the video selector 32 has an input terminal 40 for an original video signal and an input terminal 42 for an on-air video signal. The input terminal 40 is connected to a synchronization separation circuit 44 and a superimpose signal generation circuit 46, and the synchronization separation circuit 44 separates the synchronization signal from the original video signal.
Further, the superimpose signal generation circuit 46 can form a character superimpose signal of only the character portion from the script image.

The input terminal 42 is connected to a level shift circuit 48 for lowering the amplitude of the on-air video signal.
A mixing circuit 50 for mixing these output signals is provided downstream of the level shift circuit 48 and the superimpose signal generation circuit 46. The mixing circuit 50 is connected to a white level setting device 52 for setting a white level signal. The white level setting device 52 mixes the superimposed signal with an on-air video signal in white. In addition,
The color of the superimpose signal is not limited to white.

The output terminal 56 of the video selector 32
The switching circuit 54 is connected. The switching circuit 54 is switched by a control signal of the operation unit 30 and has a c terminal,
One of the d terminal and the e terminal is connected to the output terminal 56. An original video signal is supplied to the c terminal, an on-air video signal is supplied to the d terminal, and the mixing circuit 5 is supplied to the e terminal.
A video signal of two images mixed at 0 is supplied.

The operation unit 30 includes switches 34, 36, 38
By pressing the switches 34, 36, and 38, respectively, the connection of the switching circuit 54 is connected to the c terminal, the d terminal,
Switch to the e terminal. Therefore, the output terminal 56
, An original video signal, an on-air video signal, or a two-image video signal is output and transmitted to the viewfinder 20 in FIG. As a result, the viewfinder 20 displays one of a script image, a captured image, or a mixed image of the script image and the captured image. The switches 34, 36, and 38 of the operation unit 30 are, for example, as shown in FIG.
The zoom rate demand 26 and the focus position demand 28 are provided. This allows photographers to
Switches 34, 36, 3 without releasing the hand from zoom rate demand 26 or focus position demand 28
Press 8 to switch images. Note that a switch (not shown) for switching the page of the script image displayed on the viewfinder 20,
A switch (not shown) for scrolling left and right may be provided on the zoom rate demand 26 and the focus position demand 28. Further, a knob for adjusting the white level may be provided on the zoom rate demand 26 or the focus position demand 28.

Next, the operation of the electronic script device configured as described above will be described.

When an image is taken by the television camera device 10, an on-air video signal as shown in FIG. 3A is supplied to the input terminal 42 of the video selector 32. The on-air video signal is reduced in amplitude by the level shift circuit 48, becomes the signal shown in FIG. 3B, and becomes a light gray video signal with reduced luminance.

On the other hand, the input terminal 40 of the video selector 32
Is supplied with an original video signal as shown in FIG. This original video signal is stored in a storage unit such as a memory as an original video signal by previously photographing the script original with a camera or the like. The original video signal input from the input terminal 40 is supplied to a superimpose signal generation circuit 46. Then, based on the synchronization signal from the synchronization separation circuit 44, as shown in FIG.
A superimpose signal of only the character portion is obtained.

The superimpose signal and the on-air video signal are supplied to a mixing circuit 50. And
When the superimpose signal has a high output, a white level signal is superimposed on the on-air video signal from the terminal b, and a two-image mixed video signal shown in FIG. 3E is output.

Therefore, when the switch 38 of the operation unit 30 in FIG. 2 is pressed to connect the terminal e of the switching circuit 54, the video signal of two images is output from the mixing circuit 54. Therefore, two images as shown in FIG. 4, that is, two images obtained by superimposing the captured image and the script image are displayed on the viewfinder 20 of FIG. This allows the cameraman to simultaneously view the captured image and the script image without diverting the line of sight from the viewfinder 20.

As described above, according to the electronic script apparatus of the present embodiment, since the photographed image and the script image are simultaneously displayed on the viewfinder 20, the script can be read without diverting the line of sight from the viewfinder 20. Therefore, the zoom operation and the focus operation can be performed quickly and accurately while reading the script. In particular, in the present embodiment, the captured image and the script image are displayed in a superimposed manner,
The captured image and the script image are displayed large on the entire screen of the viewfinder 20, and the captured image and the script image are easy to see.

In the above embodiment, the operation unit 3
0 switch 34, the terminal c of the switching circuit 54
Is connected to output the original video signal, and only the script image is displayed on the viewfinder 20. When the switch 36 is pressed, the terminal d of the switching circuit 54 is connected to output an on-air video signal, and the viewfinder 2 is turned on.
In 0, only the photographed image is displayed. Therefore, the switch 34 and the switch 36 of the operation unit 30 are alternately pressed,
If the image reflected on the viewfinder 20 is switched between the original image and the photographed image, the photographer can use the viewfinder 2
The script image and the photographed image can be viewed without deviating the line of sight from zero.

FIG. 5 shows the structure of the second embodiment.
In the second embodiment, two images are formed by a picture-in-picture method.

As shown in FIG. 5, the video selector 60 of the second embodiment is provided with a gate pulse generating circuit 62 and an image synthesizing circuit 64. In the image composition circuit 64,
The original video signal input from the input terminal 66 and the original video signal input from the input terminal 68 are supplied, and the gate pulse generating circuit 62 is supplied with the original video signal input from the input terminal 66. You. In the gate pulse generating circuit 62, a gate pulse for cutting out a part of the script image is formed from the synchronizing signal separated from the original video signal, and the gate pulse is supplied to the image synthesizing circuit 64.

In the image synthesizing circuit 64, a predetermined area F (see FIG. 6) is cut out from the script image by the gate pulse. An image is formed. When the e terminal of the switching circuit 54 is connected, the two image signals synthesized by the image synthesizing circuit 64 are output from the output terminal 56 to the viewfinder 20 (see FIG. 1).
Supplied to As a result, two images of picture-in-picture are displayed on the viewfinder 20, as shown in FIG. 6, and the original image and the photographed image are simultaneously displayed. Therefore, the photographer can use the viewfinder 20
The script image can be read without distracting the eyes. In the second embodiment, the script image hidden in the area F can be displayed by scrolling the script image vertically or horizontally.

The display example of the two images in the second embodiment is not limited to the image shown in FIG. 6, but may be displayed as shown in FIGS. 7 and 8, for example. In FIG. 7, the script image is divided in the horizontal direction, the upper side is cut out, and a photographed image compressed in the vertical direction is fitted into the cut out portion.
In FIG. 8, the script image is divided in the vertical direction, the right side is cut out, and a photographed image compressed in the horizontal direction is fitted into the cut out portion.
