JPH01217550A - Display control system during clause resegmenting - Google Patents

Abstract

PURPOSE:To attain clause resegmentation desired by a user by surely displaying some characters to include the termination of a clause during resegmentation even when the tip end and terminal end of the clause during resegmentation can not be simultaneously displayed in a display area. CONSTITUTION:When the reading data of the resegmenting clause are displayed, next calculation is executed in the course of resegmentation. At first, a CPU 10 executes the calculation to obtain a display starting position needed to receive the terminal position of the clause in the display area. Even when the leading position of the clause to be a display object is received in the display area as the present display starting position, the display starting position is corrected with priority to receive the terminal position in the display area when this terminal position is not received. Accordingly, even when the display area is limitted, some characters to include the terminal end of the resegmented clause are certainly displayed at least.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Field of Application) The present invention relates to a document creation device using a kana-kanji conversion method that has a phrase reshuffling function, and particularly relates to a document creation device using a kana-kanji conversion method that has a phrase reshuffling function. Regarding display control methods.

(Prior Art) In general, a document creation device that applies the kana-kanji conversion method divides the reading data string inputted from an input means into phrases, performs kana-kanji conversion, and performs homophone candidate strings that constitute the converted phrase string. Alternatively, a part thereof is displayed in a predetermined display area to allow the user to confirm the selection of a homophone (homonym). However, the phrase breaks in the above-mentioned kana-kanji conversion may differ from what the user intended, even if the breaks themselves are grammatically acceptable. In order to deal with such a situation, document creation devices have been developed in recent years that have a clause re-segmentation function that changes the segmentation of clauses by a user's key operation or the like.

In this type of document creation device, the display of the phrase (character string indicating the pronunciation of the phrase) that is being reshuffled is handled in the same way as the display of a normal homophone candidate string that can be selected and confirmed. ,
It was common practice to control the movement so that at least the tip (first character) of the recut Chinese phrase would fit within the display area. There is no problem with this method because the end of the phrase is always displayed if a sufficient display area is secured. However, if a small display area is set using the multi-window function, etc., and the number of displayed characters is limited, depending on the character length of the recut middle bunsetsu, some characters including the tip (first character) may not be displayed. However, there is a possibility that several characters, including the last character (the last character), cannot be accommodated in the display area and may not be displayed. In this case, it was difficult for the user to change the desired phrase.

(Problems to be Solved by the Invention) As mentioned above, conventionally, if the size of the display area is significantly limited, there is a risk that the end of the phrase to be recut may not be displayed. There was a problem in that the user could not change the phrases as desired because the breaks between the phrases could not be visually recognized.

Therefore, it is an object of the present invention to provide a display control method during phrase reshuffling that allows the user to perform phrase reshuffling operations as desired even when the number of characters in the phrase being reshuffled is greater than the number of characters that can be displayed in the display area. Make it an issue to be solved.

[Structure of the Invention (Means for Solving the Problems) This invention provides a method in which the number of characters in the phrase being recut is greater than the number of characters that can be displayed in the display area, and the beginning and end of the phrase being recut are simultaneously hidden from display. This system is characterized in that, when possible, the end of the phrase is displayed with priority over the beginning.

(Operation) According to the above configuration, some characters including the end of the phrase being recut are always displayed, so the break in the phrase can be clearly seen, and therefore the phrase can be rearranged as desired by the user. Become.

(Embodiment) FIG. 1 is a flowchart showing a homophone display control processing procedure according to an embodiment of the present invention, and FIG. 2 is a block diagram of a document creation device using a kana-kanji conversion method that implements the above processing procedure.

In FIG. 2, 10 is a microprocessor (hereinafter referred to as C
(referred to as PU), 11 is a RAM accessed by the CPU 10, and 12 is a ROM.

CPU10 controls the entire device, and the RAM
By accessing II and ROM 12 and activating a program according to input instructions, document creation processing using the kana-kanji conversion method, homophone display control processing as shown in FIG. 2, etc. are executed. RAM 11 includes a document area, a line image area (print buffer), a non-character registration area, a phrase registration area (none of which are shown), and a homophone display buffer for storing homophone display data blocks to be described later. l
An area such as la is secured. ROM12 is CPUl
A program area 13 stores input/output programs including a program for determining the operation of 0 and a homophone display control routine as shown in FIG. 1, a character pattern area 14 for storing display or print character patterns, etc. It has a dictionary area 15 etc. in which various dictionaries for converting readings input in kana or romaji into kanji are registered.

Also, 16 is a keyboard (KB), 18 is a display, 21
23 is a floppy disk device (FDD) and a printer (PRT). The keyboard (KB) 1G uses a keyboard interface (
The data is input to the CPU 10 via the KB-IF) 17. This keyboard 16 includes various character keys (up, down, left and right).
In addition to the cursor keys, etc., there are conversion/transition keys used to instruct kana-kanji conversion, instructions to switch homophone candidates, selection/execution keys used to instruct homophone selection and execution of various processes, and more. Various function keys (none of which are shown) are provided, including a bunsetsu reshuffling key used to instruct bunsetsu reshuffling using an arbitrary character string of the bunsetsu string obtained by kana-kanji conversion as one bunsetsu. It will be done. Display 18
consists of, for example, a liquid crystal display device displaying 10 rows. The display controller (display-CNT) 19
The display of the display 18 is controlled using a display RAM (dot memory) 20 under the control of the display 18. The floppy disk device 21 has a disk interface (FDD-I).
F) Save the created document and store external characters etc. under the control of CPU10 via 22. The printer 23 prints a created document or character information read into the main body from the floppy disk device 21 through a printer interface (PRT-IF) 24 under the control of the CPU 10.

FIG. 3 shows the data structure of the homophone display data block stored in the homophone display buffer lla of FIG. 2 and provided for display on the display 18. This display data block is basically managed in units of clauses. The data for each clause (divided block) includes type information that indicates the display attributes of the character strings that make up the clause, offset information that indicates the offset from the starting position of the clause on the document, and the number of characters that make up the clause ( It consists of the number of displayed characters) and the character code of each character that makes up the relevant clause. The type information takes a value from 0 to 4, and when it is 0, there is no display attribute, indicating that the corresponding phrase (character string) is a confirmed character string. In addition, if the value is 1, the corresponding phrase is displayed in reverse video, indicating that it is a character string in which the phrase is being edited, and if the value is 2, the phrase is overlined with a thin line and the phrase is a homophone (undefined). Furthermore, if the value is 3, the corresponding phrase is underlined with a bold line, indicating that it is the homophone that is the target of the selection operation (the currently selected homophone candidate). If the value is 4, the corresponding clause (corresponding character string) is underlined with a thin line to indicate that it is the reading being input.At the end of the display data block, there is a symbol indicating that it is the end of the block. A predetermined end code indicating this is attached.

FIG. 4 shows the structure of input parameters for a homophone display request passed from the kana-kanji conversion control means to (the execution means of) the homophone display control routine of FIG. This input parameter includes the valid data start address and
Includes the number of valid data (number of clauses). First, the valid data head address indicates the address of the head data (clause) that is the subject of the current display request, among the data (clauses) stored in the homophone display buffer lla. In addition, when the number of valid data (number of clauses) is 0, it indicates that all data after the specified address is valid (target of display request), and 1
A value above (here, 1 or 2) indicates that the specified number of data (clauses) is valid.

Next, the operation of one embodiment of the present invention will be explained with reference to the flowchart of FIG. 1 as appropriate.

First, when a character key on the keyboard 1B is operated and a reading is input, the CPU 10 inputs the reading one character at a time from the keyboard interface 17 and stores it in the RAM.
The data is stored in an input buffer (not shown) in 11.

Eventually, when the conversion/next candidate key on the keyboard 16 is operated, the CPU 10 divides the reading data string stored in the input buffer into phrases and uses the dictionary area 15 in the ROM 12 to perform the well-known kana-kanji conversion process for each phrase. and obtain all the homophone information that is the result of the conversion. CPU10
is the homophone with the highest priority among this homophone information (
(here, words with particles etc.) are extracted for each clause, and the display data block in the format shown in Figure 3 (here,
A data block having a display attribute indicating that the first phrase is the selected homophone and that all remaining phrases are undetermined homophones is generated and stored in the homophone display buffer lla.

Next, CPU10 generates an input parameter in which the valid data first address is the address indicating the first data (clause) of the data block in FIG. 4, and the number of valid data is 0 (all data after the valid data first address is specified). Then, the homophone display control routine shown in FIG. 1 is activated. As a result, the display data blocks stored in the homophone display buffer lla are retrieved and displayed in a predetermined display area of the display 18 with the specified display attributes in order from the first data. That is, the kana-kanji conversion result of the reading data string inputted by the user by operating the keyboard 16 is displayed on the display 18 in the form of a homophone string. Here, the first homophone (clause) is displayed with a display attribute indicating that it is being selected, and each subsequent homophone is displayed with a display attribute indicating an undetermined homophone. Note that data portions that do not fit within the display area are not displayed. In addition, when displaying the above, the character pattern area 1 of the ROM 12
Of course, processing for converting the character code into a character pattern and developing it in the display RAM 20 is performed with reference to 4.

In the above homophone string display state, the user performs homophone conversion (switching) and selection operations. That is, if the selected homophone is a word with the desired notation, the user selects/selects the keyboard 16 to instruct (select) the homophone (character string).
The execution key is operated, and if the word is not in the desired notation, the user operates, for example, the conversion/next candidate key on the keyboard 16 to instruct switching (conversion) to a homophone in another notation.

Assume that the selection/execution key is now operated in the homophone display state. In this case, CPU10 is the homophone display buffer]
, rewrite the type information of the corresponding clause (homophone) in la to the confirmed character string display attribute and the next clause to the selected display attribute, and change the effective data start address in Fig. 4 to the address indicating the corresponding clause. and the number of valid data is 2
The input parameters are generated and the homophone display control routine of FIG. 1 is activated. As a result, the corresponding clause, that is, the clause for which selection confirmation was instructed, is redisplayed with the display attribute changed to no attribute, while the notation remains unchanged, and the next clause remains unchanged, but only the display attribute is selected. It will be switched to the state and redisplayed.

It is assumed that the above selection confirmation operation is repeated several times and that the conversion/next candidate key is operated this time. In this case CPU10
replaces the data of the corresponding clause (selected clause) in the homophone display buffer lla with the data of the next candidate homophone (another word with the same pronunciation but different spelling). If the number of characters of the next candidate homophone does not match the number of characters of the previous homophone, the offset information of the data of all subsequent clauses (homophones) is rewritten. In addition, in this case, since the display position of the subsequent phrase changes, the effective data start address in FIG. 4 is set as the address indicating the corresponding phrase, and
An input parameter with the number of valid data set to 0 (that is, an input parameter requesting redisplay of all phrases after the corresponding phrase) is generated, and the homophone display control routine of FIG. 1 is activated. On the other hand, if the number of characters of the next candidate homophone matches the number of characters of the previous homophone, then the following clause (
Since the offset information of the data of the homophone (homophone) is not rewritten and the display position of the subsequent clause does not change,
In the figure, an input parameter (in other words, an input parameter requesting redisplay of only the corresponding phrase) with the effective data start address set as the address indicating the corresponding phrase above and the number of valid data equal to 1 is generated, and the homophone display shown in FIG. 1 is generated. A control routine is started.

Now, in the homophone display control routine shown in FIG. 1, first, the active homophone flag, all homophone display flags (none of which are shown), etc., which will be described later, prepared in a predetermined area in the RAM 11 are initialized. (reset) (step S1.). Next, it is checked based on the type information of the corresponding clause in the display data block in the homophone display buffer lla (step S2), and if the answer is No as in this embodiment, the next Step S5 described in
°S6 is executed. First, in step S5, a calculation is performed to find the display start position (on the document) necessary to fit the end position of the phrase (homophone) to be displayed (requested for display) within the display area.

The next candidate homophone mentioned above (the newly selected homophone)
is to be displayed, and if the number of characters is the same as the previous homophone, the display start position will not change. In the next step S6, a calculation is performed to find the display start position (on the document) necessary to fit the beginning position of the phrase (homonym) within the display area. Even if the end of the homophone to be displayed fits within the display area at the current display start position, if the start position does not fit, priority is given to keeping this start position within the display area. The display start position is corrected.

When step S6 ends, it is determined whether screen movement (change of display start position) is necessary (step S7).
. This determination is first made regarding the next candidate homophone that is newly being selected, and if screen movement is not required, the process advances to step 317. Since this display target homophone has the currently selected display attribute, it is determined that the above display request is a display request for the currently selected homophone (hereinafter referred to as an active homophone display request), and that An active homophone display flag is set (step S1?,
818). Next, since the all homophone display flag, which indicates that all homophones in the homophone display buffer lla have been displayed, is in the reset state, one entry of the homophone to be displayed (in this case, the next homophone that becomes the active homophone) candidates) are displayed on the screen (step 520). Next, it is checked whether all the requested data has been displayed (step 521), and in this example, where only the first clause has been displayed, the answer is No.

Furthermore, it is checked whether or not the homophone data has ended (step 52).
2), No in this example where subsequent homophone data exists. In this case, a homophone data pointer (not shown) for specifying the next homophone data in the homophone display buffer 11a is incremented by 1 (step 523), and the process returns to step S2. Then, the above-described process is performed on the next homophone (the next candidate in the active homophone display state).

Now, if the number of characters of the active homophone does not match the number of characters of the homophone before switching the homophone, subsequent homophones may fall outside the display area unless the display start position is changed and the screen is moved.

If screen movement is required, it is checked whether or not the homophone to be displayed is requested to be displayed as an active homophone by referring to the type information attached to the data (steps S7 and S8). Since the homophone to be displayed this time is not an active homophone, the process proceeds to step 81B, where it is checked (by the set/reset state of the active homophone display flag) whether or not an active homophone is already displayed.

Since the answer is YES here, the process proceeds to step S17 described above, skips step 818, and steps S19 to S8
23 processes are performed. That is, if the active homophone is already displayed, screen movement is prohibited even if subsequent homophones cannot be displayed in the display area unless the screen is moved.

Therefore, it is possible to reliably prevent the inconvenience that the screen movement (screen scrolling) occurs when trying to display some homophones following the active homophone, and the viewpoint for the active homophone moves.

The above homophone switching is not limited to the conversion/next candidate key, but also when operating the no-conversion key, which instructs to confirm to "Hiragana", and the Katakana conversion key, which instructs to confirm to "Katakana", etc. may also occur, but this case is handled in the same way as above.

Note that for the homophone data that becomes the active homophone, if both the leading and ending positions cannot be placed within the display area without moving the screen, step S7. From S8 to Step S9 onwards Step S
A well-known screen scrolling process up to 15 is performed. If screen scrolling is also prohibited for such active homophones, the entire active homophone cannot be seen, and the operability will be adversely reduced.

Next, the display of homophones during segmentation will be explained.

First, it is assumed that a homophone string, which is a result of kana-kanji conversion, is displayed on the display area of the display 18. If there is a phrase in this homophone string that differs from the phrase break intended by the user, the user operates the phrase change key to instruct the phrase to be changed.

When CPU10 detects this instruction, it updates the display data block in the homophone display buffer lla of RAM II to a data block containing the reading data of the specified recut phrase (character string). The type information of the reading data of the phrase being recut is set to a value of 1 indicating that the phrase is being recut. Along with the generation of the display data block, a homophone display input parameter that specifies the reading data of the recut clause as the first data of the display request is also generated, and the homophone display control routine of FIG. 1 is activated. If the display position of the subsequent homophone string changes due to phrase switching, O is used as the number of valid data of the input parameter.

Now, when displaying the reading data of the first phrase to be displayed, that is, the phrase after phrase cutting, the determination in step S2 is YES.
Since S, the next step S3. S4 is executed. First, in step S3, a calculation is performed to find the display start position necessary to fit the beginning position of the phrase for which display has been requested (the phrase being recut) within the display area. In the next step S4, a calculation is performed to find the display start position necessary to fit the end position of the phrase (the phrase being recut) within the display area. Even if the beginning position of the phrase to be displayed fits within the display area at the current display start position, if the end position does not fit, priority is given to keeping this end position within the display area. The display start position is corrected. When step S4 is completed, the process proceeds to step S7, and the subsequent operation is almost the same as the operation when the phrase is not being changed. However, step S
3. It should be noted that in the process of S4, the terminal position of the phrase to be recut is displayed with priority. That is, according to this embodiment, even if the number of characters displayed in the display area is extremely limited, at least some characters including the end of the recut phrase are always displayed.

[Effects of the Invention] As detailed above, according to the present invention, even if the beginning and end of the phrase being recut cannot be displayed simultaneously within a limited display area, any part of the phrase including the end of the phrase being recut cannot be displayed simultaneously. Since the characters are always displayed, the break between phrases can be clearly seen, and therefore the user can change the phrases as desired.
