Description

[Detailed description of the invention] [Summary] In a Japanese input display control method that inputs and converts readings, when the length of the conversion result is shorter than the length of readings, the readings are erased by the display. In order to restore the original screen at high speed, the screen before reading and displaying is saved in bitmap format, and when displaying the conversion result, the saved screen is restored to speed up the display speed. is possible.

[Industrial application field]

The present invention relates to a Japanese input display control method in workstations, word processors, etc.
In particular, the present invention relates to a Japanese input display control method that enables high-speed restoration of the original screen portion that is temporarily erased to display the reading when displaying the conversion result.

If the Japanese conversion input processing is slow, keystrokes from the keyboard will not be reflected on the screen quickly, which will hinder smooth input operations. Therefore, high speed is required for conversion input on a character display screen, and high speed is also required for screen restoration processing, which is one phase of conversion input.

[Conventional technology]

FIG. 3 is a diagram for explaining the conventional method.

In the figure, 30 represents a display screen.

For example, as shown in FIG. 3A, it is assumed that the display screen 30 before reading display is displaying "red, blue, yellow, green, white...". Here, the cursor is "red"
If the pronunciation of ``Murasaki'' is input at the position , the pronunciation is overwritten and displayed on the original screen as shown in FIG. 3B.

When the reading of “murasaki” is converted to “purple” by a conversion instruction using the “conversion” key, etc., the third
As shown in Figure C, it is necessary to restore the "blue, yellow, and green" characters that have been temporarily erased due to the reading display. In the conventional system, the character code before reading and display is stored, and when restored, the character code is redeveloped into a dot pattern one character at a time and displayed.

[Problem that the invention seeks to solve]

According to the conventional method, it is necessary to compare the length of the reading and the length of the conversion result, which makes the process complicated, and if the length of the conversion result is shorter than the length of the reading, the original characters are converted one by one. Since it is necessary to develop the pattern and display it again, there is a problem in that the processing takes time.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems and provides a method that can quickly restore a screen when the length of the conversion result is shorter than the length of the reading.

[Means for solving problems]

FIG. 1 shows a block diagram of the principle of the present invention.

In FIG. 1, 10 is a processing unit including a CPU and memory, 11 is a bit map display, 12 is a keyboard, 13 is a dictionary storing readings and conversion result information corresponding to the readings, 1
4 is a reading input buffer in which a reading code is stored; 15 is a reading input display processing unit that inputs a reading and displays the reading; 16 is a character code buffer that stores the converted character code; 17 is a conversion instruction A conversion processing unit searches the dictionary 13 and extracts the character code of the conversion result, 18 is a conversion result display processing unit that displays the conversion result, and 19 is a character generator (CG) that develops the character code into a dot pattern. 20 is a screen bitmap memory in which screen data corresponding to the display screen is stored in bitmap format.
Reference numeral 1 represents a screen save processing unit that performs processing to save the contents of the screen bitmap memory 20, and 22 represents a save area for screen data.

In the case of the present invention, a save area 22 in which screen data of the screen bitmap memory 20 is saved is provided in advance. This save area 22 has a size that allows at least the maximum length of display screen data allowed for reading input to be stored.

When inputting the reading, the screen saving processing unit 21
Screen data in the screen bitmap memory 20 corresponding to the current cursor position on the screen of the bitmap display 11 is transferred to the save area 22.

When the reading is input from the keyboard 12,
The reading input display processing section 15 stores the reading code in the reading input buffer 14, and the character generator 19 converts it into a character pattern corresponding to the reading code, which is then stored in the screen bitmap memory 20. will be expanded to. The contents of the screen bitmap memory 20 are displayed on the bitmap display 11.

When there is a conversion instruction, the conversion processing unit 17 is activated, and the conversion processing unit 17 uses the dictionary 13 to convert the reading code into a Japanese character or a Japanese character string. The character code of the conversion result is notified to the conversion result display processing section 18.

When displaying the conversion result, the conversion result display processing section 18 copies the screen data saved in the save area 22 to the original position in the screen bitmap memory 20. The character code resulting from the conversion is then set in the character buffer 16, and expanded into a character pattern corresponding to the character code via the character generator 19.

From now on, the display of readings that are no longer needed will be erased, and the new conversion result will be overwritten and displayed on the original screen.

[Effect]

In the present invention, a save area 22 is provided, and the screen save processing section 21 and conversion result display processing section 18 save/restore the original screen with the image of the character pattern intact. Therefore, after reading conversion, if the length of the conversion result is shorter than the reading length, there is no need to expand and display each character again into a character pattern, speeding up the conversion input process. .

Note that the screen data is saved/restored by the screen save processing section 21 and the conversion result display processing section 18 as follows:
For example, a circuit such as a so-called bit mover that transfers data in a rectangular area in a bit map using hardware can be used.

〔Example〕

FIG. 2 is a processing explanatory diagram of one embodiment of the present invention.

Hereinafter, the processing related to one embodiment of the present invention will be explained according to the processing shown in FIG.

For example, assume that the display 11 displays the words "red, blue, yellow, green, white...". It is assumed that the cursor is at the "red" position. The screen data is stored in the screen bitmap memory 20 in the form of a dot pattern bitmap. The screen save processing unit 21 shown in FIG. 1 copies and saves the screen data before inputting the reading and displaying it from the screen bitmap memory 20 to the save area 22 in bitmap format. Note that the length to be saved is the maximum length allowed for reading input.

The reading input display processing section 15 shown in FIG. 1 inputs and displays the reading. For example, as a reading,
When “Purple” is input, the screen bitmap memory 20 will display a message above “red, blue, yellow, green”.
The kana character pattern for ``Murasaki'' will be written.

It is determined whether a conversion instruction has been given using a "conversion" key or the like. If there is no conversion instruction, control is returned to the process and reading input continues in the same way.

When there is a conversion instruction, Dictionary 1 depending on the reading
Search for 3.

The character code of the conversion result corresponding to the reading, for example, the character code of "purple" is obtained from the dictionary 13.

When displaying the conversion result, the screen data saved in the save area 22 by processing is copied to the original position in the screen bit map memory 20, and Green-white…” is restored.

The character code "purple" resulting from the conversion is developed into a character pattern by the character generator 19, and the result is written into the "red" position in the screen bitmap memory 20. As a result, the new screen display becomes "purple, blue, yellow, green, white...".

As in this example, the length of the save/restore is set to the maximum length allowed for reading input, the save/restore is performed uniformly, and the screen data of the conversion result is overwritten on the restored screen data. With this configuration, there is no need to compare the length of the reading and the length of the conversion result, which speeds up the process and also simplifies the process. Note that even if reading is canceled, the original screen can be restored from the save area 22 in the same way.

〔Effect of the invention〕

As explained above, according to the present invention, when displaying the conversion result, the restoration of the original screen is accelerated and the conversion input processing is accelerated, so that keystrokes from the keyboard are quickly displayed on the screen. This will enable smooth input operations.
