After the NAPLPS code for Japanese sentence is decoded by the NAPLPS decoder 36, the result is fed to a video RAM 37, then a picture for a character or a graph corresponding to the key input is displayed on a monitor 40 and the Japanese sentence corresponding to the NAPLPS code based on the Japanese sentence selected by a keyboard 60 is displayed on the monitor 40 at the same time. Further, in correcting the size, shape or color of the Japanese word, it is executed immediately while observing the pattern. Thus, the Japanese sentence is generated or corrected easily and simply.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a videotex terminal device equipped with a Japanese text creation means suitable for application to NAPLPS type videotex and the like.

[Summary of the invention]

This invention is based on the NAPLPS method (North Aseer
ican Pres-entation Level
Regarding the Videotex terminal device suitable for application to Videotex etc. of Protocol 5yntax (North American Videotex Communication Code), in particular, the NAPLPS terminal device has a built-in means for creating Japanese sentences, and Japanese text input directly from the keyboard can be written. Internal NAPLPS text code
By converting to NAPLPS code with a decoder,
This allows Japanese sentences to be displayed in real time on top of characters and figures generated by the NAPLPS method.

[Conventional technology]

The NAPLPS method is known as one type of videotex.

Now, in order to create Japanese sentences using this NAPLPS type Videotex terminal device, it is conceivable to adopt the method shown in FIG. 2.

That is, generally, a Japanese word processor 10 is used as shown in the figure, and data of Japanese sentences encoded by this word processor 10 is supplied to an encoder 20 for NAPLPS code.

In this encoder 20, the size of Japanese characters,
NAPLPS codes representing shapes, angles, revenge, etc. are added, and the Japanese NAPLPS codes thus formed are added to the NAPLPS codes for displaying characters and figures generated by other NAPLPS code generating devices.

After decoding these NAPLPS codes, images are displayed on the monitor 40 based on both codes.

Note that the NAPLPS system uses a code transmission method in which all character and graphic information is encoded and transmitted.
The code is the control set code (C.

The decoder 30 decodes these codes to display predetermined characters and figures.

[Problem that the invention seeks to solve]

By the way, when displaying Japanese text using such means, it is necessary to add the NAPLPS code to the Japanese text code created by a word processor. At this time, the NAPLPS encoder 20
NAPLPS-specific control code C for character color, angle, size, writing direction, etc. displayed by LPS code
This Japanese code is created after anticipating the appropriate shape and size of the characters while considering the size of figures etc. represented by other NAPLPS codes to which Japanese is added (a type of PDI cent code). The NAPLPS code to be added to the data must be determined.

Therefore, if the display form of Japanese characters is out of proportion to the displayed image such as a figure on the screen, it is necessary to change the NAPLPS code added to the Japanese code.

When adopting such a means of creating Japanese, it is not possible to change the size, shape, color, etc. of the Japanese while looking at the screen at the same time, and it is necessary to display Japanese on the screen one by one. It is necessary to check the consistency status and change the Japanese NAPLPS code each time if it is unbalanced.
It was tedious and took a lot of time to code.

Therefore, in this invention, we have developed a NAPLPS with a means for creating Japanese sentences that solves these conventional problems in a simple manner.
This paper proposes a videotex terminal device that can be applied to this system.

[Means for solving problems]

In order to solve the above-mentioned problems, in the present invention, as shown in FIG. 1, a kana/kanji conversion means 64 is provided in the NAPLPS terminal device so that Japanese sentences can be input directly from the keyboard 60.

The output data of the kana/kanji conversion means 64 is immediately converted to NAPL.
The signal is transferred to the PS encoder 35 and converted into a NAPLPS code.

[Effect]

In this configuration, at the same time as the encoding of the NAPLPS code corresponding to the characters and figures generated on the terminal device side, the Japanese text code sent from the keyboard 60 is also encoded.
Since it is converted into NAPLPS code using an APLPS encoder, Japanese sentences can also be displayed on the monitor in real time.

In addition, NAPLPS is displayed in the display area set on the terminal device side.
Since the characters and figures obtained by decoding the code will be displayed on the monitor 50, the NAP is set so that the Japanese sentence code obtained from the keyboard can also be displayed in this display area.
Converted to LPS code. Therefore, the Japanese text can be displayed at an appropriate position in accordance with the sketch, and it is also easy to modify it.

〔Example〕

FIG. 1 is a system diagram showing an example of a terminal device for videotex according to the present invention, and 30 is a terminal device for NAPLPS (hereinafter referred to as a workstation because it also functions as a workstation in this example). , I10 port 32 accepts line data from a communication line as well as image data from a video camera and image data from a video source.

At the workstation 30, a computer executes image processing, data conversion, etc.

That is, the workstation 30 is provided with a CPU 31, and the image data transmitted via the connector 32 is once taken into the buffer RAM 34 via the I10 port 33, and the image data read from this is stored in the N.
It is supplied to the encoder 35 for APLPS, and the NAPLP

Data in video RAM 37 is used as addressing data for color palette 38.

Color palette 38 is provided to achieve the following objectives.

That is, as the videotex code signals inputted to the connector 32, R, G, and B color image data are digitally converted into 4 bits, respectively, and are converted into respective videotex code signals and transmitted. Therefore, this image data may include color image data of a maximum of 4096 colors. Such image data is not stored as is in the video RAM 37, but is
The image data of 096 colors is associated with the image data of 16 colors, and a color image is displayed based on the associated image data.

Therefore, the encoder 35 stores image data associated with these 16 colors in the form of NAPLPS codes, and is also provided with a color palette 38 capable of reproducing color images of at least 16 colors.
The address of 8 is specified by the image data stored in the video RAM 37.

Image data specifying a specific color read out from the color palette 38 is converted into an analog signal by a D/A converter 39, and this is supplied to a monitor 40 to display a predetermined color image.

On the other hand, the image data of the NAPLPS code stored in the encoder 35 is stored in the buffer RAM 41 or the floppy disk 42, or both.
The output connector 44 is transmitted via the I10 port 43 to the host side via a data line such as a telephone line.

With this configuration, control codes such as the color, angle, size, and writing direction of Japanese characters to be displayed on the monitor 40 can also be created by operating the keyboard 60 and inputting them at the same time as creating the Japanese text. can do. Also, monitor 4
Since Japanese text can be created using the 0 display area along with image data such as a sketch, the color, size, arrangement, etc. of the characters can be set to match the sketch.

Of course, since the corresponding Japanese text can be displayed on the monitor 40 at the same time as the keys are pressed from the keyboard 60, this Japanese text can be displayed in real time. Also, when you want to correct the size, shape, color, etc. of Japanese words, you can do it immediately while looking at the screen.

〔Effect of the invention〕

As explained above, according to the present invention, the NAPLPS terminal device is provided with the Japanese language conversion encoder 64, and this conversion encoder 64 and the NAPLPS encoder 35 are used to convert Japanese characters input using the keyboard 6o. Since it is immediately converted to NAPLPS code, it has the following characteristics compared to the conventional method.

First, use the keyboard 60 to create a Japanese sentence, and at the same time input control codes such as the color, angle, size, and writing direction of the Japanese characters to be displayed on the monitor 40 from the keyboard 6o. Therefore, these control codes can be created at the same time.

Therefore, at the same time as the key input from the keyboard 60,
In order to be able to display the corresponding Japanese text on the monitor 4o,
This Japanese text can be displayed in real time, and the size, shape, color, etc. of the Japanese text can be instantly adjusted while looking at the screen.

Furthermore, since Japanese text can be created along with image data such as a sketch using the display area of the monitor 40, the color, size, arrangement, etc. of the characters can be set to match the sketch.

For this reason, the present invention has the feature that it is possible to easily and easily create Japanese sentences by effectively utilizing the effects of character information possessed by NAPLPS.
