BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device suitable for use, for example, in a viewfinder of an integrated video camera.

0002

[Prior Art] In general, the viewfinder of a video integrated camera displays characters (for example, the current time displayed in a clock pattern, zoom magnification, iris amount, remaining tape amount, etc.) along with the original captured image (video image). ) are known to be displayed at the same time.

In this case, the captured image and the character are displayed within the same display area (for example, an effective screen area with a 4-3 aspect ratio on a viewfinder according to the NTSC system).

0004

[Problem to be Solved by the Invention] However, since it is necessary for the display of the character to not interfere with the display of the captured image, the display content of the character cannot be displayed in many ways. It is expressed.

[0005] Therefore, the photographer must first take his or her eyes off the viewfinder to judge what kind of camera operation he or she is currently doing or what the shooting conditions are around the shooting location. It is necessary to do it.

[0006] That is, it is necessary to take one's eyes off the viewfinder to check the status of operation switches, the clock, photographing conditions, etc., making it cumbersome to use, and some kind of equality has been desired.

[0007] An object of the present invention is to provide a display device in which a video image and various characters can be viewed at the same time, and in which usability is improved.

[0008]

[Means for Solving the Problems] A display device according to the present invention, as shown in FIGS. 1 and 2, for example, displays a desired video image A.
A first display area 50A in which desired characters a, b,
a second display area 50B in which c, d, and e are displayed;
Display control means 5, 13, 21, 23, 29, 33 for individually displaying video image A and characters a, b, c, d, e in display area 50A and second display area 50B, respectively.
It has the following.

[0009]

[Operation] In the display device according to the present invention, a character different from the video image is displayed in the second display area different from the first display area where the video image is displayed, so that various characters can be displayed. At the same time, the video image and the character can be viewed simultaneously.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the display device according to the present invention will be described below with reference to the drawings.

As understood from FIG. 1, in the circuit showing the main part of this embodiment, a composite video signal is input from the input terminal 3 to the Y/C separation (color signal-luminance signal) circuit 7.

The color signal is R. G. B. Decoder (red, green,
The blue color signal is input to AP (demodulation) 9, while the luminance signal is input to AP
The signal input to the C circuit 11 and output from the APC circuit 11 is
R. G. The signal is input to the B decoder 9.

[0013]R. G. B. The output signal of the decoder 9 is R.
G. B. The signal is input to the driver 13, and the driver 13 outputs a driving signal for displaying the video image A (see FIG. 2) in the area 50A of the panel 50 (display control means).
.

On the other hand, the output signal of the Y/C separation circuit 7 is input to the AFC circuit 17 via the synchronization separation circuit 15 and is made into a phase-synchronized clock signal (master clock).

Further, the clock signal is input to a time generator 19, and its output signal is input to a pulse driver 21, where it is converted to a level suitable for driving the panel 50.

The driver 21 has a pulse driver 21A for H (horizontal) timing and a pulse driver 21B for V (vertical) timing, and these drivers 21A, 21B
The output signal is input to the panel 50.

In this case, the output signals of the drivers 21A and 21B are used as clock signals for displaying video images and characters.

The panel 50 also serves as a viewfinder 120 of a video integrated camera, as can be seen from FIG.
As shown in FIG.
0A and characters (a “light amount”, b “iris amount”, c
("zoom magnification", d "clock", e "year, month, day") display area 50B.

Next, the display contents of characters a to e are read by a microcomputer 29 built into the camera from the camera/VTR signal processing section 25 and temporarily stored in the memory 27.
Store in.

The microcomputer 29 drives the character generator 23 horizontally and vertically in synchronization with the output signal of the timing generator 19, and converts the display contents stored in the memory 27 into R in synchronization with the output signal of the generator 23. ．． G. B. R. via the lookup table 31. G. B. output to the driver 23, R
．． G. B. A character is displayed in the display area 50B using a signal converted by the driver 23 to drive the liquid crystal (display control means).

As explained above, in this embodiment, video image A and characters a to e are individually displayed in area 50A and area 50B, respectively.

[0022] Therefore, the camera user can visually recognize the characters a to e while looking into the viewfinder 120, thereby improving the usability of the camera.

In addition, by preparing various contents for the characters a to e, it is possible to enjoy photographing.

[0024] The present invention also relates to an LCD image display device, etc.
It is also applicable to other display devices, and the characters can also be used as movie captions.

[0025]

[Effects of the Invention] As understood from the above explanation, in the display device according to the present invention, a character different from a video image is
Since the video image is displayed in a second display area different from the first display area where the video image is displayed, various characters can be displayed, and the video image and the characters can be viewed at the same time, resulting in excellent usability.
