[Industrial application field]

The present invention is capable of storing moving image information and still image information from a natural image input unit such as a camera or image scanner, and character/graphic information from a character/graphic input unit such as a keyboard in the same file, and can be used in a father-type combination display device. The present invention relates to a multimedia processing device capable of displaying images.

[Conventional technology]

FIG. 6 is a block diagram of a conventional multimedia processing device.

When processing character figures, the expression colors are 8 colors (23) to 16
Color (24) is said to be sufficient, and the expression color of one pixel can be expressed with 3 to 4 bits.

However, when processing natural images, the number of expression colors is 4096 (
2'') to 16.7 million colors (2'') are required, and the expression color of one pixel needs to be expressed with 12 bits to 24 bits.

Therefore, it is not possible to store natural image information in a file that stores text and graphic information, and redundant parts will occur if text and graphic information is stored in a file that stores natural image information.

Therefore, as a conventional multimedia processing device, the sixth
As shown in the figure, a natural image processing section 30 that temporarily stores natural image information in a file and displays it on a display device, and a text and graphic processing section 31 that temporarily stores text and graphic information in a file and displays it on a display device are separated. ing.

The data structure of natural image information and character/figure information is as shown in FIG. 5, and the natural image information input from the camera 1-1 and image scanner 1-2 in FIG. (If the pixel data is, for example, 12 bits representing 4096 colors, the number of displayed colors is 4096 to indicate the division of data) and pixel data, and the character information is a character code (indicated by numbers) and character color (for example, 3 bits), and the graphic information consists of a code (indicated by a number) indicating the display position and type of figure, such as a circular line, and the figure color (for example, 3 bits).

The video information from the camera 1-1 in FIG.
The still image information from the image scanner 1-2 is converted into a digital signal by the A/D converter 10 of the image scanner 1-2, and is stored in a file 16 under the control of the processor 13.

When displaying this stored information on the display device 8, the process is controlled by the processor 13 or the drawing processing unit 1
5, perform processing such as enlargement and reduction 9 rotations, etc., and save it to natural image memory 1.
4, is read out, and is sent to the display device 8 through the solid line side of the display switching device 21 and displayed.

On the other hand, character and graphic information input from the keyboard 2 is stored in the file 20 under the control of the processor 17 of the character and graphic processing section 31.

When displaying this stored information on the display device 8, it is read out from the file 20 under the control of the processor 17. If it is a character, it is converted into a character by the character generation unit 11 from a character seed, and if it is a figure, it is converted into a character by the character seed. The code indicating the type is converted into a figure by the drawing processing unit 19, and when processing such as enlarging or reducing one revolution is performed, the drawing processing unit 19 processes it, and the code is written and read out to the character/figure memory 18 and the display is switched. It passes through the dotted line side of the device 21 and is sent to the display device 8 for display.

[Problem that the invention seeks to solve]

However, as explained above, conventional multimedia processing devices have the problem that natural image information and character/graphic information cannot be stored in the same file.

Also, since they cannot be stored in the same file, the natural image processing section and the character/figure processing section are separate, so even if they are displayed on the display device 8, the natural image A synchronization signal for writing information into the natural image memory 14, reading it out, and displaying it on the display device 8, and a text/figure memo 18 for text/figure information.
There is a problem that the signals are not synchronized with the synchronization signal that is written to and displayed on the display device 8, and that they cannot be displayed on the same screen at the same time.

In the case of a television, text and graphic information is also input from the camera, stored in the same file, and displayed simultaneously on the same screen.

An object of the present invention is to provide a multimedia processing device that can store natural image information and character/graphic information in the same file and display them simultaneously on the same screen.

[Means for solving problems]
