Description

[Detailed description of the invention] Skin gloss! The present invention relates to a character string display method, and particularly to a character string display method in a character string processing device that derives a corresponding character string from an input character string, such as a Japanese word processor or a translation machine.

For example, in the "kana-kanji conversion" method widely adopted in Japanese word processors, a converted character string is generated from an input character string in units of words or units of minutes. this is,
Since word processing such as confirmation and correction of Kanji words is performed on a word-by-word or segment-by-segment basis, there is a drawback that the frequency of operator intervention, that is, the frequency of keystrokes, is high.

On the other hand, in the so-called "solid writing conversion" method, the word breaks are extracted and converted to kanji for a string of reading characters input continuously in kana or romaji, and therefore the processing of the string is done in writing. Since it is a unit, it has the advantage of being simple to operate.

In the character string display method in a character string processing device using solid writing conversion, it is required to be able to clearly visually confirm whether or not the converted character string intended by the operator, that is, the Kanji/Kana mixed character string, has been generated for the input character string. For example, when creating a new document, if word usage frequency learning has not yet matured, the probability that the operator's intended conversion result will be displayed first is not necessarily high, and it may be difficult to select the next candidate word. The need to perform operations is relatively high. therefore,
In order to perform this operation efficiently, it is required that the correspondence between the input character string and the converted character string that is the result of its conversion be displayed in some form.

SUMMARY OF THE INVENTION The present invention satisfies such requirements and aims to provide a character string display method that can improve the operability of character string input.

4-Problem The configuration of the present invention will be described below based on one embodiment.

Referring to FIG. 1, a block diagram shows an embodiment in which the present invention is applied to a Japanese word processor. As shown in the figure, this embodiment includes a keyboard 20, a display 22, and a RAM 2 for storing programs and data.
4 and ROM 2B, and a processor 28 such as a microprocessor. Character string processing using the solid writing input method in this device is realized by functional blocks conceptually shown in FIG.

In this embodiment, the keyboard 20 is used for inputting reading (phonetic) characters such as kana or alphabets.
7-1″-ILL, =ht”7’-I A″8°°
````5). Further, a cursor forward key, a cursor back key, a word cursor forward key, and a word cursor back key are used to move the identification display displayed on the display screen 100 (FIG. 3) of the display 22, that is, the cursor 110 (FIG. 7, etc.) forward or backward. The cursor movement instruction unit 32 includes function keys including function keys. Of course, the keyboard 20 has other function keys, but since these are not directly relevant to understanding the present invention, their explanation will be omitted. Note that in this specification, the term "r character" includes not only kana, kanji, or alphabets, but also punctuation marks and other symbols.

The display 22 may be, for example, a CRT character display device, and displays reading character strings input into the system.

The character string resulting from the Kana-Kanji conversion is displayed visually. As shown in FIG. 3, the display screen 100 includes a converted character string display section 48 in which the converted character string that is the conversion result, that is, the converted character string is displayed, and a converted character string display section 48 in which the conversion operation mode is displayed in the left half. It has an input character string display section 50 in which an indication "Kana/Kanji" indicating the conversion mode is displayed, and an input character string is displayed in the right half.

In this embodiment, the other display area 102 is a text area that displays a character string for which the conversion result has been determined. For example, the data displayed in area 102 can be handled as information processing data.

Note that herein, the character string after conversion will be referred to as a converted character string.

The kana-kanji conversion unit 34 is a functional block that converts an input character string input in solid writing from the data input unit 30 into a kanji-kana mixed character string using a commonly available kana-kanji conversion method. Broadly speaking, this has a word extraction function that extracts words from input reading character data, and a kanji conversion function that converts portions of the extracted words that correspond to kanji into kanji. The kana-kanji conversion unit 34 indexes the kanji dictionary and the grammar dictionary for the data indicating the input reading character string, and executes the kana-kanji conversion process. Since the specific processing in these functions is not directly related to the understanding of the present invention, a description thereof will be omitted.

The converted character string storage unit 38 is a buffer that temporarily stores the converted character string converted into a Kanji-kana mixed sentence by the kana-kanji conversion unit 34, that is, data indicating the conversion result. This conversion result is stored in each storage location word by word, as shown in FIG. 4, for example.

In this example, ``I'' is from address A to just before B.
is stored in the memory locations from address B to before address C. Note that in the same figure, word boundaries are indicated by "/".

The stored contents of the converted character string storage section 38 are stored in the identification display generation section 4.
0, it is transferred to the converted character string display section 4B of the display 22 and displayed on the screen 100.

The input character string storage unit 42 is a buffer that temporarily stores data indicating input character strings. The input character string is stored in each storage location word by word, as shown in FIG. 5, for example.

In this example, "Watakushi" is stored in the storage locations from address a to before address b, and "ha" is stored in the storage location from address b to before address C.

The stored contents of the input character string storage section 42 are stored in the display section instruction section 44.
is transferred to the input character string display section 50 of the display 22 and displayed on the screen 100.

The correspondence relationship between which word in the converted character string corresponds to which word in the input character string is generated in the corresponding address generation unit 4B. As an example is shown in FIG. 6, the corresponding atray generation unit 48 stores the addresses A, B, C, etc. where words of the input character string are stored in the input character string storage unit 42, and the converted character string storage unit 3 days. Addresses a, b, c, etc. of the words of the corresponding converted character string stored in are stored in association with each word.

Cursor 1 instructed by the cursor movement instruction section 32
10 (Fig. 7, etc.) is performed using the cursor position indicator 3.
6 is converted to the display position of the input character string display section 50. Advantageously, this cursor display position is represented in the form of a storage location address in the input character string storage 42 or data related thereto. This will cause cursor 11
0 is input character string display section 50 by 1 display section instruction section 44
will be displayed at the indicated display position.

The identification display generation unit 40 also generates an identification display (a type of cursor) 112 (such as in FIG. ) is generated. This identification display 112 may be, for example, inverted characters, but is shown as /\ latching in FIG. 7 and the like.

The operation of this embodiment will be explained with reference to the display examples shown in FIGS. 7 to 10 and the operation flow shown in FIG. 11.

For example, as shown in the example shown in FIG. 7, when the input character string "Watashi wa Kyou" is input from the data input section 30 of the keyboard 20, this is converted into the character string "Watashi wa Kyou" by the kana-kanji conversion section 34. is converted to The input character string "I am here" is stored in the input character string storage section 42, and the converted character string "I am today" is stored in the converted character string storage section 38.

This accumulation state is shown in FIG. 5 and FIG. 4, respectively. These are transferred to the input character string display section 50 and the converted character string display section 4 by the display section instruction section 44 and the identification display generation section 40, respectively, and are displayed on the screen 100.

At this time, the cursor movement designation unit 32
When movement of 0 is instructed (200, 202, Fig. 11)
, the cursor position instruction unit 3B performs an operation to convert this instruction into a cursor position (204). The display section instruction section 44 receives this cursor position data from the cursor position instruction section 36, reads the input character string data from the input string storage section 42, and moves the cursor +10 at the timing of the display position specified by the cursor position data. Generates a display pattern and displays the input string display section 5 along with the input string data.
0 (20B). Therefore, as shown in the left half of FIG. 7, if the cursor position data indicates the position of address C shown in FIG. A cursor 110 is displayed.

On the other hand, the corresponding address generation unit 46 uses the kana-kanji conversion unit 34
The input character string and the address of the storage location of the corresponding converted character string in the storage units 38 and 42 are received from , and the correspondence is stored word by word. Therefore, when cursor position data is received from the cursor position indicating means 38, the word of the converted character string corresponding to the address of the word containing the character of the input character string indicated by the cursor position data is stored in the storage unit 42. (210). The searched address is sent to the identification display generation section 40.

The identification display generation unit 40 receives the retrieved address of the storage unit 38, reads the converted character string data from the converted character string storage unit 38, and generates the identification display 112 at the timing of the display position specified by the address. Generates a display pattern and displays the converted string display section 4 along with the converted string data.
Transfer to 8. In this example, if the address of the cursor +10 indicates C (Fig. 5)'-, the corresponding converted character string word "J" is specified from address B to C (Fig. 4). As shown in the left half of FIG. 7, the word "ha" in the converted character string display section 48 is displayed in reverse (112) (212). In this way, the reverse display 112 functions as a word-by-word cursor in the conversion display section 48.

As shown in FIG. 7, for example, when the cursor forward key is operated in the state shown in the left half of the figure, the cursor 110 moves forward due to the operation described above, and the input character string display section 50 displays the next word ""Kyou" is displayed, and the cursor 110 is displayed at the beginning of the word.

Also, the related conversion string "Today" is highlighted (
112) To be done. This state is shown in the right half of the figure.

Similarly, as shown in FIG. 8, if the cursor back key is operated in the state shown in the left half of the figure, the cursor +10 moves back and the previous word "Kiyo" is displayed in the input character string display section 50. is displayed, and the cursor 110 is displayed at the end of the word. Furthermore, the related converted character string "Today" is displayed in reverse video (112)9. This state is shown in the right half of the figure.

Similarly, as shown in FIG. 9, if the word cursor forward key is operated in the state shown in the left half of the figure, the cursor 110 moves forward and appears in the input character string display section 50 due to the above-described operation. The first word "Kaishiya" is displayed, and the cursor +10 is displayed at the position of the first character "Ka" of that word. Further, the related converted character string "company" is highlighted (112), and this state is shown in the right half of the figure.

As shown in FIG. 10, when Mr. M operates the word cursor buff key in the state shown in the left half of the figure, the cursor 110 moves back and the input character string display section 50 displays the previous word ""Kiyo" is displayed, and the cursor 110 is displayed at the position of the first character "Ki" of the word. Also, the related converted string “Today” is highlighted (112)
be done. This state is shown in the right half of the figure.

Since the present embodiment is configured in this way, the correspondence between an input character string and its corresponding converted character string is clearly displayed. Therefore, for example, the operation of correcting erroneous input, ie, the operation of moving the cursor to the corrected position map, is simple, and there is no need to re-enter the input character string.

Note that the embodiments described here are for explaining the present invention, and the present invention is not necessarily limited thereto, and modifications and variations that can be made by those skilled in the art without departing from the spirit of the present invention. Modifications are within the scope of this invention.

肱-1 Since the character string display method according to the present invention is configured as described above, the correspondence between an input character string and its corresponding converted character string is clearly displayed. Therefore, the operability of character string input is improved, especially in the solid writing conversion method.
