Abstract

PROBLEM TO BE SOLVED: To relieve the burden of an key operation in the case of inputting a single KANJI(Chinese character) in KANA(Japanese syllabary)/KANJI conversion for converting an idiomatic phrase by converting character strings into KANJI, judging propriety in the list display of obtained KANA/KANJI conversion candidates and displaying the candidates by means of list, which are judged to be possible in list display. SOLUTION: It is judged whether an inputted signal is a KANJI conversion indication or not (S2). Inputted KANA characters are successively stored in a KANA input buffer (S3). A KANA character string is converted into plural KANJI character strings to be the candidates and stored in a KANA/KANJI conversion candidate buffer in priority order (S4). It is judged whether the plural stored KANJI character strings to be the candidates are the ones to be displayed by change-over or the ones to be displayed by list (S5). The KANJI character strings which are judged to be the change- over candidates are successively stored in a change-over display output buffer in order (S6). The KANJI character strings judged to be displayed by list are stored in a list display output buffer in order (S7). The display of the stored KANJI conversion candidates and the selection and establishment of the candidates are controlled (S8).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a kana-kanji conversion method and apparatus in a document processing apparatus such as a Japanese word processor or a portable information processing apparatus such as a mobile phone.

[0002]

2. Description of the Related Art To input a kanji string, input a kana character string corresponding to the kanji string to be input from a keyboard.
There is a device that converts a kana character string into a kanji string in response to an input of a kanji conversion key. Press the kanji conversion key to convert the entered kana character string to a kanji string, press the katakana conversion key to convert it to katakana, or press the no conversion key to keep it in hiragana. When the last candidate is called, a sentence can be input by, for example, pressing a pre-conversion key. (Sanyo Electric's Japanese word processor SWP-M55 Manual "Sanw
ord manual introductory course ”etc. On the other hand, in a portable information processing device represented by a mobile phone, the device itself is downsized to emphasize portability, so that a display device for displaying characters is downsized. Many can display only a few characters per line.

Conventionally, in an information processing device equipped with a small display device, input of kanji by single kanji conversion is a main Japanese input method. A plurality of single kanji candidates are displayed at a time, and a desired one is selected from among them. Has been selected based on a user's instruction and input in units of one character. Recently, information processing devices equipped with small display devices, such as mobile phones, can be used to convert multiple kanji characters at a time, in order to make it easier to use Japanese input. Some have a conversion function. However, since the number of characters that can be simultaneously displayed on the display device is small, after inputting a kana character string, the kanji conversion key is depressed, and conversion candidates are switched and displayed for each candidate. Therefore, even in the case of inputting a single kanji, it is necessary to switch and display conversion candidates one by one by pressing a kanji conversion key as in the case of inputting a kanji. That is, if the idiom input is realized on a device having a small number of characters that can be displayed, the operation becomes complicated when single Kanji characters are input.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the burden on the user in the kana-kanji conversion input in an information processing apparatus having a small display device. An object of the present invention is to reduce the burden of key operations when inputting single kanji.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A kana-kanji conversion apparatus according to one embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a functional block diagram according to one embodiment of the present invention.

The input unit 1 is composed of a pen-type input device using a small keyboard or a digitizer, and executes various editing functions, sets various modes, designates a character code string, and inputs character data.

The output unit 2 is constituted by a liquid crystal display or the like, and displays character data, windows, menus, cursors and the like.

The control unit 3 performs a process according to an instruction from the input unit 1 together with input / output control.

The kana input buffer 5 stores a kana character string input from the input unit 1.

The kana-kanji conversion processing section 4 converts the kana character string stored in the kana input buffer 5 into a kanji character string using the kana-kanji conversion dictionary section 7. A plurality of Kanji conversion results are output to the Kana-Kanji conversion candidate buffer 6 in order of priority from the top.

The kana-kanji conversion candidate buffer 6 is a buffer that stores a plurality of candidates for kana-kanji character strings that are kana-kanji conversion candidates.

The kana-kanji conversion dictionary 7 associates a kana character string, which is a reading of a word, a kanji kana mixed character string, which is a notation, grammatical information such as part of speech of a word, and usage frequency information used for determining a priority order. It is stored.

The output display method determination processing unit 8 compares and determines the length of the character string of the kana-kanji conversion candidate stored in the kana-kanji conversion candidate buffer 6 with a predetermined number of characters, and based on the determination result, determines the kana-kanji conversion candidate. The kanji character string is stored in either the switching display output buffer 10 or the list display buffer 11.

The switching display output buffer 10 stores candidates for switching display in which a plurality of kana-kanji conversion candidates are switched and displayed one by one as shown in FIGS. The list display output buffer 11 stores candidates for displaying a list as shown in FIG. 6 among a plurality of kana-kanji conversion candidates.

The output candidate output order control unit 9 switches the kana-kanji conversion candidates stored in the switching display output buffer 10 or the list display output buffer 11 in accordance with a key operation from the input unit 1 and displays the switching display and the list display. , And the selection and selection of candidates.

The processing operation of the control unit 3 will now be described.
This will be described with reference to the flowchart in FIG.

Step S0 is an initialization process in which the kana input buffer 5 is initialized, and usually, input character string information and the like are initialized.

In step S1, an input signal from the input unit 1 is processed.

In step S2, it is determined whether or not the signal input from the input unit 1 in step S1 is a kanji conversion instruction. In the case of a kanji conversion instruction, the process proceeds to step S4,
If the input signal is a kana character, the process proceeds to step S3.

In step S3, the kana characters input in step S1 are sequentially stored in the kana input buffer 5.

FIG. 3 shows the state of the display device when the kana character string "Kaki" is input. The input kana character string “Kaki” is in an inverted state, and is a kana-kanji conversion target character string. The cursor is located at the position of the last "ki" of the input kana character string, and the kana-kanji conversion target is up to this cursor position.

FIG. 7 shows the input kana character string "Kaki".
The state stored in the kana input buffer 5 is shown.

In this state, when a kanji conversion instruction is issued from the keyboard of the input unit 1, the processing in step S4 is performed according to the determination in step S2. In step S4, the input character string is converted into a plurality of candidate kanji using the word reading and grammatical information such as the part of speech stored in the kana-kanji conversion dictionary 7 and the frequency information. It is converted into a character string and stored in the kana-kanji conversion candidate buffer 6 in the order of priority. The state in which the input character string “Kaki” is converted to kanji and stored in the kana-kanji conversion candidate buffer 6
Shown in the figure. "Below""persimmon""summer""summer""fence"
They are stored in the order of "oyster" and "relief".

In step S5, it is determined whether a plurality of kanji character strings stored as candidates in the kana-kanji conversion candidate buffer 6 are candidates for switching display or candidates for list display. The determination is made based on the length of a kanji character string that is a preset candidate. In the present embodiment, the length of the kanji character string set in advance is set to 1. In this case, a list is displayed if the number of characters is one or less, and a switching display is displayed if the number is two or more.

In step S6, the kanji character strings determined to be switched and displayed based on the determination in step S5 are sequentially stored in the switching display output buffer 10. FIG. 9 shows kanji strings stored in the switching display output buffer from kanji conversion candidates for the input kana character string "Kaki".

In step S7, the kanji character strings determined to be displayed in a list based on the determination in step S5 are sequentially stored in the list display output buffer 11. FIG. 10 shows kanji strings stored in the switching display output buffer from kanji conversion candidates of the input kana character string "Kaki".

In step S8, display of the kanji conversion candidates stored in the switching display output buffer 10 and the list display output buffer 11, and control of selection and confirmation of the candidates are performed. Control is
As shown in FIG.
Display suggestions. Next, the character string stored in the switching display output buffer 10 is stored in the fifth display until there are no more candidates stored in the switching display candidate in response to an instruction from the input unit 1 of the user.
Switching display is performed as shown in the figure. The user can make a selection by inputting a confirmation key or a kana for the next conversion when a desired candidate is displayed.

When there are no more candidates stored in the switching display buffer, the candidates stored in the list display output buffer 11 are displayed as shown in FIG. At the time of list display, numeric keys are assigned from the left candidates. For example, in the case of FIG. 6, pressing the numeric key 1 enables selection of "persimmon" and pressing the numeric key 2 allows selection of "fence".

In this embodiment, the control is performed so that the switching display is displayed first, but the list display may be performed first. Further, control may be performed such that the kanji string corresponding to the first priority of the conversion candidate is displayed first by the corresponding display method. 8th
In the case of the figure, the first candidate “below” is a switching display candidate. In this case, all the switching display candidates are displayed first, and then the list display is performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments.

[0036]

According to the present invention, even if the display screen is small, character strings are sufficiently short, and conversion candidates that can be displayed in a list are displayed in a list.
Facilitate candidate selection. As a result, the burden on the user when inputting a character string using kana-kanji conversion is reduced.
