2. Description of the Related Art Conventionally, the method of displaying characters on the screen has been a simple method such as simple character display or scroll display of characters. For this reason, the characters were only for reading, and could not be used for impressing the characters with a strong impression.

[0003]

SUMMARY OF THE INVENTION In view of the above points, the present invention creates and stores some character screens having different positions, directions, sizes, etc., and displays these screens sequentially. An object of the present invention is to provide a display method for displaying not only characters that can be moved vertically and horizontally as well as diagonally, but also by freely changing the size and direction of the characters.

[0004]

In order to solve the above problems, the present invention exchanges the input information with a character image information input device such as a personal computer for inputting the character image information.
/ F means, a RAM for storing the information, and a VRAM for converting the stored character image information into a character video signal and storing the converted character image signal.
A sync generation means for generating a sync signal such as a horizontal sync signal; and a D / A conversion means for converting a character video signal stored in the VRAM in synchronization with the sync signal into an analog signal.
Video output means for synthesizing and outputting the analog video signal from the sync signal from the sync generation means, ROM for storing various programs, control means for controlling the respective parts, plasma display device for displaying the video signal, etc. It is composed of a display device, and a plurality of character image information from a personal computer or the like is stored in a memory such as a RAM, which is sequentially read at arbitrary intervals and displayed on the display device to move the characters displayed on the screen, The size and other directions are changed.

[0005]

With the above configuration, according to the character display display method of the present invention, a plurality of character image information from a personal computer or the like is stored in a memory such as a RAM and sequentially read out at arbitrary intervals. By displaying the characters on the display device, the characters displayed on the screen can be freely moved in the vertical and horizontal directions, and the size and the like can be freely changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a character display display method according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a system block diagram showing an embodiment of a character display display method according to the present invention. Reference numeral 1 denotes an interface (hereinafter referred to as I / F), which exchanges information with a character image information input device 20 such as a personal computer. is doing. Reference numeral 2 denotes a RAM that stores the input character image information divided for each screen. A video input unit 3 inputs a video signal from the tuner 30, the video camera 31, and the like. Reference numeral 4 is an A / D conversion means, which digitally converts the input video signal. A VRAM (1) 5 stores the digital video signal. Reference numeral 6 is a video synthesizing means for superimposing the character image information stored in the RAM on the digital video signal. A VRAM (1) 7 stores the digital video signal to be combined. Reference numeral 8 is a synchronization generating means for generating a synchronization signal such as a horizontal synchronization signal. 9 is D
The A / A conversion means synchronizes with the synchronization signal to generate VRAM.
The digital video signal of (2) is converted into an analog video signal. Reference numeral 10 is a video output means for adding a synchronizing signal to the analog image acquisition signal to display a plasma display, CR
It is output to the display device 40 such as a T display. 11
Is a ROM that stores various programs. Reference numeral 12 is a control means, which according to the program stored in the ROM,
It controls each part.

The operation of the above structure will be described below. FIG. 2-a shows an example of a plurality of character image information created by an input device such as a personal computer. In this example, the position and direction of the character are arranged vertically and horizontally on each screen, but the size and angle of the character are different. Etc. may be changed. The image information is
It is input from the I / F 1 and stored in a predetermined location of the RAM 2 for each screen. Further, FIG. 2-b shows the video camera 3.
1 shows a video signal input from 1 etc., input from the video input means 3, A / D converted by the A / D conversion means 4 and VR.
It is stored in AM (1) 5. FIG. 2-c shows the RAM 2
Is a diagram in which a plurality of character image information stored in the VRAM (1) 5 is combined with the video signal stored in the VRAM (1) 5, and is temporarily stored in the VRAM (2) 7. For example, (1) in FIG. 2-c is a diagram obtained by combining (1) in FIG. 2-a and (1) in FIG. 2-b, and (2) in FIG. 2-a (2) and FIG.
FIG. 2C is a diagram obtained by combining (2) of FIG. 2-b, and (3) of FIG. 2-c is a diagram obtained by combining (3) of FIG. 2-a and (3) of FIG. 2-c (4) corresponds to (4) in FIG. 2-a.
And (4) in FIG. 2-b are combined. In this example,
Although the figures with the same numbers were combined, they can be combined with different combinations. The digital video signal stored in the VRAM (2) 7 is read in synchronization with the sync signal from the sync signal generation means 8 and converted into an analog signal by the D / A conversion means 9, and the sync signal is added to the video output. It is output from the means 10. The video signal is input and displayed on the display device 40 such as a plasma display. In this example, the video signal input to the video input means 3 is converted into A by the A / D conversion means 4.
It was converted to D / D and once stored in VRAM (1) 5.
The AM (1) 5 is not provided, and the character image information stored in the RAM 2 is combined into a video signal for A / D conversion, and VRAM is used.
(2) It may be stored in 7.

[0008]

As described above, according to the character display display method of the present invention, the character information, etc., which is created and stored in a personal computer or the like and is moved vertically and horizontally is read out at an arbitrary interval, and the camera is read. Since it can be combined with the input video signal and displayed from the etc., the character you want to emphasize,
It can be moved up and down, left and right, and can be displayed by changing the size, angle, etc. of the characters according to the video signal, and a character expression method that can give a strong impression that has never been achieved can be realized.
