2. Description of the Related Art Generally, in a character input device for inputting Japanese, a reading of an input character string is input and converted into a desired character string by a kana-kanji conversion process. Further, when inputting a graphic symbol, a user generally switches the input mode to the “graphic symbol mode” or the like and selects a desired graphic symbol from the displayed graphic symbols.

Most of the character input devices described above have a word registration function for kana-kanji conversion processing, and by using this function, a graphic symbol can be input without switching the input mode. For example, for the graphic symbol "○",
Register the word by reading "maru". After that, "○"
In the case of inputting the graphic symbol of "," it is possible to input "maru" as a reading without conversion to the symbol mode and convert it into the graphic symbol of "○" by the kana-kanji conversion processing. As a result, it is not necessary to switch modes when inputting a graphic symbol, and the number of operation steps for the user can be reduced.

[0004]

However, the method of registering words in advance as in the prior art is a troublesome task for the user. Further, in the method of registering words as described above, it is only possible to input a graphic symbol to a word such as a noun that has no inflection. That is, there is a problem in that even if the graphic symbol of “>” is registered as a word with the reading “large”, the input of the reading “large” cannot be converted into “>”.

The present invention is to provide a character input device capable of converting even a word having an inflection, from reading to a graphic symbol and increasing versatility in inputting a graphic symbol by kana-kanji conversion. With the goal.

Next, an input device for inputting characters will be described with reference to FIG. FIG. 2 shows a keyboard which is a kind of input device for inputting characters. In FIG. 2, reference numeral 207 is a key to be pressed when a character is input. When the character key 207 is pressed according to the character type set by pressing the character type setting keys 202 to 204, a signal corresponding to the character is output. 20
2 can be set to alphanumeric characters, 203 can be set to hiragana, and 204 can be set to katakana. For example, 203
If the character type is set to Hiragana by pressing, 207 is output by pressing the key. Similarly, if the character type is set in 202, it becomes "3", and if the character type is set in 204, it becomes "A". Further, by pressing 207 while pressing 206, it is possible to further output characters different in character type. For example, "a" is output if the character type is hiragana, "a" is output if it is katakana, and "#" is output if it is an alphanumeric character. Next, 201 in FIG. 2 will be described. Reference numeral 201 denotes a Roman character input designating key for designating an input method of hiragana or katakana. Note that the Roman character conversion method uses a known method. Next, a conversion key for generating a character string conversion signal for converting the input character string into a character string intended by the user will be described. Two
A kana-kanji conversion key 09 is pressed when converting the input character string into a reading character string and converting it into a character string containing kana-kanji characters. When this key is pressed, the Kana-Kanji conversion key generates a predetermined character string conversion signal, and when the conversion key determination unit determines that Kana-Kanji conversion is performed, the Kana-Kanji conversion unit determines the target character string as a known Kana-Kanji character. It is converted into a kana-kanji character string by the conversion method and the result is output. 21
Reference numeral 0 denotes a pictographic character conversion key, which is pressed when the input character string is used as a reading character string and is converted into a pictographic character string in which characters are mixed with pictures and images. When this key is pressed, the pictogram conversion key generates a predetermined character string conversion signal, and when the conversion key determination unit determines that the pictogram is converted, the pictogram conversion unit displays the target character string as a picture or image. It is converted into a mixed pictogram string and the result is output. Details will be described later. Reference numeral 208 denotes a non-conversion key, which is pressed when returning to the original input character string state when the target character string is the input character string converted state. When this key is pressed, the target character or pictographic character string is input and the input character string stored in the character string storage buffer is read, and the result is output. Conversion key determination unit 904
Determines whether or not the key information pressed to convert the input character string is a predetermined character string conversion signal for kana-kanji conversion or pictogram conversion, and instructs each conversion unit.

Note that the keyboard arrangement of the key blocks shown in FIG. 2 does not necessarily have to be this way, and there is no problem in implementing the present invention even if the keyboard arrangement is different.

Next, the pictogram conversion unit 905 will be described. When a character string is input and the pictogram conversion key 210 is pressed, the pictogram conversion unit 905 performs morphological analysis on the reading of the target character string by the analysis means and the reading obtained as a result by the pictogram conversion means. Use Emoji Dictionary 906
To search. The pictogram conversion unit 905 searches the pictogram dictionary 906 for the reading of the character string that matches the reading of the character string,
The picture, image, or symbol corresponding to the matched character string is the output candidate. The candidate is the pictogram candidate storage buffer 9
It is stored in 07. Here, it is assumed that the picture or image output by the pictographic character conversion unit is a part of the character and can be handled in the same manner as an ordinary character. The pictogram dictionary 906 has reading and notation of character strings, and the notation corresponding to reading is a font of a picture or an image. Further, it is also possible to have a phonetic guide for the notation as a ruby, and in that case, it may be held as a part of the font of the pictogram, or may be stored as a ruby in the dictionary in addition to the reading and notation. An example of a pictographic dictionary is shown in FIG. In FIG. 4, reference numeral 401 denotes a heading, which contains readings for pictograms. 402
Is a ruby for emoji. In this case, the ruby is stored in the 1/4 corner of the character string. Reference numeral 403 is a pictograph having a font of a picture or an image as a character code. The pictogram dictionary is a collection of records in which these pieces of information are one record.

Next, the ruby processing determination section 911 will be described. Pictogram candidates as shown in FIG. 7 are displayed, and ruby selection is also displayed as one of the candidates. When a pictogram is displayed, if ruby is added to the pictogram, the ruby selection key 702
Should be selected. Alternatively, one of the keys of the keyboard of the input device may be provided with a ruby selection key to receive a selection instruction as to whether or not to add ruby. By these methods, a signal as to whether or not ruby is attached is generated,
The signal is read to select whether or not to add ruby. If attached, ruby processing unit 912 performs processing for attaching ruby. The ruby processing unit 912 reads the ruby for the pictogram from the pictogram dictionary, processes the deviation of the pictograph string caused by the place for attaching the ruby and the length of the ruby, and uniformly assigns the ruby to the pictogram. As a result, the pictograph with ruby is output.

Next, an embodiment of the character input method in the character input device of the present invention will be described. Input of a character string is accepted from the keyboard as shown in FIG. For example, assume that the input of a character string as shown in FIG. The state of the screen at this time is shown in FIG. Figure 6
In (a), the system area 603 displays a conversion 604 indicating that the target character string can be converted into Kana-Kanji or pictograms. Edit area 601
, The input character string is displayed in a black area 606 indicating that the character string is an object of the convertible character string. At that time, conventionally, the character string is only fixed or converted into a kana-kanji mixed character string by pressing the conversion key. Conventionally, in order to input a picture or image in this character string, it has to be input by a dedicated function key.
In the present embodiment, it is possible to convert an input character string into a picture or image in the same way as converting a kana-kanji character using a pictographic dictionary.

The flow of processing in this embodiment will be described below with reference to FIG. 1 for the example of the character string as shown in FIG. First, the input device 902 receives a character string composed of inputs 1 or 2 and a character string conversion signal as input information (S101). In the above example, FIG.
Input character string shown in (a) "Let's do it."
Then, pressing the pictogram conversion key 210 in FIG. 2 becomes input information. Next, the conversion key determination unit 904 determines the key information pressed to convert the input character string (S102). If the conversion key 209 shown in FIG. 2 is pressed, known kana-kanji conversion is performed (S104). If the pictogram conversion key 210 is pressed, the pictogram conversion unit 9
05 performs pictogram conversion for converting a character string into a picture or an image (S103).

Here, the pictographic character conversion process will be described with reference to FIG. First, the pictographic character conversion unit 905 morphologically analyzes the input character string (S301). As an example of the morphological analysis result of the above example, FIG. 10B is given as an example. Figure 10
As shown in (b), with respect to the input character string “Let's do Harare de Nissho”, the division for each part of speech is output as a morphological analysis result. Next, the processes 302 to 307 are repeated in order from the beginning of the reading obtained as a result of the morphological analysis. If the reading obtained as a result of the morphological analysis is a noun and the ending is changed, it is returned to the basic form (S302). For example, it is assumed that the character string "Kakimasu" is morphologically analyzed and the reading "Kakimasu" is obtained. "Oyster" is a idiom and its ending has changed, so it is returned to its basic form and the pronunciation "kaku" is obtained. Then, the pictogram conversion unit 905 searches the pictogram dictionary based on the reading (S303). In the above example, since the head reading "Hare" is not a verb, the pictogram dictionary is searched as it is. The pictogram conversion unit 905 determines whether there is a matching pictogram (S304), and if there is no matching record in the pictogram dictionary, instructs the kana-kanji conversion unit 908 to perform conversion. The kana-kanji conversion unit 908 performs kana-kanji conversion (S305).
This kana-kanji conversion uses known kana-kanji conversion. The conversion candidates converted by kana-kanji conversion are stored in the kana-kanji candidate storage buffer 910. The reading character code of the matched pictographic character is stored in the pictographic character candidate storage buffer 907 as a pictographic character conversion candidate (S306). In the above example, FIG.
In the pictogram dictionary shown in FIG.
The character code of 2 is stored in the pictographic character candidate storage buffer 907 as a conversion candidate for reading. Next, it is determined whether the end of the character string has been reached (S307), and the process 302 is performed on all the target readings until the reading character string reaches the end.
The processes of to 307 are performed, and all the matching pictograms are extracted. The output character string buffer 913 includes a kana-kanji candidate storage buffer 910 or a pictogram candidate storage buffer 9.
Of the conversion candidates stored in 07, the longer matching candidate is selected and transferred by the pictogram conversion unit 905. When the processing is completed for all the read character strings, the process returns to the flowchart shown in FIG.

After the pictogram conversion processing, the display device 915 displays the pictogram corresponding to the extracted longest character string stored in the output character string buffer 913 (S10).
5). Further, other conversion candidates for reading stored in the kana-kanji candidate storage buffer 910 or the pictogram candidate storage buffer 907 to be converted are displayed (S10).
6) Allow other candidates to be selected according to the user's intention. Here, an example of kana-kanji conversion candidate display and pictogram conversion candidate display is shown in FIGS. 11 and 7, respectively. In FIG. 11, a method is adopted in which candidates can be selected in correspondence with the numerical keys 1 to 9, and all nine candidates are notations for readings stored as a result of kana-kanji conversion. For the pictogram candidates shown in FIG. 7, a record 404 that matches the reading.
The notations of ~ 410 are displayed as candidates. The display method is shown in Figure 1.
Although it is the same as 1, the ruby selection in which the ruby for the pictogram can be added to the eight pictogram conversion results is also displayed as one of the candidates. In the above example, the display is as shown in FIG. Pictogram candidates 608 corresponding to the leading reading candidates “Hare” and “Ha” obtained as a result of the morphological analysis for the pictographic string 607 are displayed as shown in FIG. 7. In order to apply ruby to the pictogram candidate 701 in the pictogram string, the ruby selection key 702 may be selected. It is determined whether or not a ruby signal is generated (S107),
When the ruby selection key 702 is selected, a signal for adding ruby is read, and processing for adding ruby to the pictogram is performed (S
108).

The ruby processing will be described with reference to FIG. First, the ruby processing unit 912 inserts one line as a ruby line above the line with the pictogram, and eliminates the line space between the pictograph string line and the ruby line so that the pictogram and the ruby are adjacent to each other (S501). Next, the ruby is searched by referring to the pictogram dictionary 906 rather than reading the pictogram (S502). It is calculated how many characters the referenced ruby has for the character string (S503). After the calculation, the number of emoji characters and the number of ruby characters are compared (S5
04). If the number of characters is larger than the number of pictograms, the difference between the number of characters in ruby and the number of pictograms is taken (S505), and the character string after the pictograms is moved to the right by the difference. The pictogram is moved to the center of the place where the character string has moved, and is displayed together with the ruby (S50
6). At this time, a ruby display different from the display character string is displayed because the display on the display device 915 can be recognized as ruby. In the above example, after the ruby is selected, the ruby in the pictographic dictionary corresponding to the reading "Hare" is searched. Ruby processing section 912
Refers to the ruby 411 of the record 409. Ruby is 1
Since it is a / 4 corner display, the ruby 411 is a single character. Pictogram 4
Since 12 is also a single character, ruby of 1/4 corner is displayed on the pictogram without moving the character string after the pictogram.

After the ruby processing is completed, it is determined whether or not the cursor is moved by selecting a candidate for a part of the conversion target by moving the cursor or the like in the portion shown in the black area 606 (S109). If it has been moved, the conversion target is moved (S110). It is determined whether or not there is a character string that has not been converted in the black area 606 (S111), and if there is, the steps S106 to S111 are repeated. If the selection of candidates for the reading of all character strings is completed, FIG.
A character string display like 607 shown in FIG.

Further, in the above ruby processing, ruby can be added to positions other than the upper ruby by adding processing for selecting the ruby position in advance. FIG. 8 shows an example of ruby position selection. As shown in FIG. 8, the upper ruby,
Select the ruby position such as lower ruby, rear ruby, front ruby, etc. Further, 801 to 801 in FIG.
FIG. 12 shows a display example of 804. The upper ruby processing shown in 801 is as shown in the flowchart in FIG. Regarding the lower ruby shown in 802, in the process 501 shown in FIG. 5, it is only necessary to change the insertion of one row above into the insertion of one row below. The post-ruby processing shown in 803 is shown in FIG. In FIG. 13, the ruby processing unit 912 refers to ruby in the pictogram dictionary from reading (S13).
01), and calculate the number of ruby characters as a character string (S1
302). The character string after the pictographic characters is moved to the right by the number of calculated characters (S1303). A pictogram with ruby is displayed (S1304). Regarding the pre-ruby process shown in 804, instead of displaying the ruby after the pictogram in the process 1304 shown in FIG. 13, the ruby before the pictogram may be displayed.

In the ruby processing described above, the ruby information in the pictographic dictionary is referred to and the ruby information is added to the pictographic character, but it is also possible to use the reading that matches the dictionary as the ruby. Alternatively, the input character string may be used as a ruby as it is for processing. Further, without passing through the ruby processing unit 912, the pictographic character conversion unit 905 extracts the character string resulting from the morphological analysis and the pictographic characters that match the extracted character string, and displays the character string detected by the pictographic character conversion unit 905 on the display device. The phonetic text may be displayed, and the phonetic text and the extracted pictogram may be displayed.

Further, it is possible to further have a pictographic character modification dictionary which stores a character string and an attribute for modifying a character or a pictographic character corresponding to the character string. The pictographic character modification dictionary may store the reading of the pictographic character modifier and the attribute corresponding to the modifier, and add the pictographic character modification processing to the above-mentioned pictographic character conversion. For example, when "Futataneko" is input as the input character string, the normal display is enlarged and displayed as shown in FIG. An example of this processing will be shown. At the time of pictogram conversion, morphological analysis is performed on the input character string, and a reading before the reading that matches the pictogram is searched for a pictogram modification dictionary as shown in FIG. As shown in FIG. 15, the pictogram modification dictionary is a collection of records composed of a reading that serves as a headline and a modification-specific attribute for the pictogram according to the reading. If there is a matching reading as a result of the dictionary search, the attribute of the record is referred to and the processing according to the attribute is performed. In the example, the reading of "futoru" is detected as a result of the morphological analysis, and the pictogram modification of attribute 1 is performed because it matches the reading of the record 1501. The processing of the attribute 1 shown in FIG. 16 will be described. The current pictogram is horizontally enlarged to twice (1601), and the pictogram is stored instead of the conventional pictogram (1602). By adding such processing, it is possible to display a more varied pictographic character string.

Further, it is also possible to return the pictographic character string display to the original input character string and to perform kana-kanji conversion. When the conversion target is the pictographic character string display, when the non-conversion key 208 is pressed, the pictographic character string is read out from the input character string stored in the input character string storage buffer 903, and the input character string is displayed. When the conversion key 209 is pressed, the input character string stored in the input character string storage buffer 903 is referred to, and the known Kana-Kanji conversion is performed for display.

Although the pictogram conversion key is specially provided in the above embodiment, another method can be used. For example, at the time of displaying a normal kana-kanji conversion candidate, a pictogram conversion candidate may be added as one of the conversion candidates. By selecting a candidate for this pictogram conversion, the same processing as in the above embodiment can be performed. Further, when the pictogram dictionary is provided in a storage unit such as an FD, pictogram conversion may be automatically performed if the pictogram dictionary is set, or automatic pictogram conversion is set in advance as a system environment setting. Good.

Regarding the reading obtained when the morphological analysis is performed by the kana-kanji conversion, both the kana-kanji conversion and the pictogram conversion can be listed at the same time by searching the pictogram dictionary in parallel with searching the kana-kanji dictionary. You can

Further, without providing the pictographic character conversion key, both the kana-kanji character conversion and the pictographic character conversion are performed by pressing only the conversion key, and both the kana-kanji character string and the pictographic character string of the obtained result are displayed as candidates, and the user You can also select a kana-kanji character string or a pictographic character string.

Since the pictographic character string can be handled in the same manner as a character, a word can be registered by providing a registration means. At that time, the part of speech at the time of registration is added to the part of speech of "pictogram", so that the pictogram dictionary is registered by the registration means.

Further, it is also possible to register the pictogram headings and ruby by the registration means. When the headline or ruby registration is selected, the target pictogram is input, and the headline or ruby is input to register it in the pictographic dictionary. that time,
For example, multiple headings and ruby are attached to one pictogram such as "I" and "Hanako", but in the case of headings, the same pictogram can be output for all registered readings. You can attach the ruby that you intend.

Furthermore, a character input device may be used which does not include a kana-kanji conversion unit and only performs pictogram conversion. In this case, with respect to the input character string, the matching character string may be converted into a pictographic character by referring to the pictographic dictionary, and if not, the input character string may be displayed as it is.

As described above, according to the present invention, the user can input a picture or an image without changing to the graphic symbol mode, which has an effect of simplifying the operability of the input device. Further, since a picture or an image is treated like a character, the picture or the image can be converted by the same operation as the normal kana-kanji conversion, and there is an effect that the input method is not bothered.
