  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an example of a system configuration of an information processing system according to the present invention.

  As shown in FIG. 1, the information processing system according to the present embodiment has a configuration in which an electronic book terminal 101 and an external device 102 are communicably connected via a network 103.

  Hereinafter, an example of a hardware configuration applicable to the electronic book terminal 101 illustrated in FIG. 1 will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 203 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs are stored.

  A RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing from the ROM 203 or the external memory 211 into the RAM 202 and executing the loaded program.

  An input controller 205 controls input from the input device 209 or the like. A video controller 206 controls display on a display device 210 such as a liquid crystal display. The display device is not limited to a liquid crystal display, and may be a CRT display or the like. These are used by clients as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 connects and communicates with an external device via a network (for example, the LAN 400 shown in FIG. 1), and executes communication control processing in the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the display device 210 by executing outline font rasterization processing on a display information area in the RAM 202, for example. Further, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the display device 210.

  Various programs that operate on the hardware are recorded in the external memory 211 and are executed by the CPU 201 by being loaded into the RAM 202 as necessary.

  It should be noted that not all devices have these configurations, and it is only necessary to provide necessary devices.

  Next, a ruby swing process performed by the electronic book terminal 101 in the embodiment of the present invention will be described with reference to FIG.

  Note that the process shown in the flowchart of FIG. 3 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S301, the CPU 201 of the electronic book terminal 101 accepts various settings from the user via the screen shown in FIG. The setting accepted here includes a setting of magnification (601) for determining whether or not to display ruby.

  For example, in the case of 601 in the screen shown in FIG. 6, when “ruby when enlarged” is checked and “150%” is set as “magnification designation”, the magnification of the screen display is enlarged to 150% Is set to display ruby.

  Further, when “automatic” is selected instead of “magnification designation”, processing of steps S307 to S309 described later is executed, and whether or not to display ruby using data such as resolution shown in FIG. Will be determined.

  In step S302, the CPU 201 of the electronic book terminal 101 displays the electronic book data on the display unit. The electronic book data is data stored in advance in the storage area of the electronic book terminal 101 or data acquired from the external device 102.

  In step S303, the CPU 201 of the electronic book terminal 101 receives a display magnification change instruction from the user.

  The method for accepting the change in display magnification may be accepted by the user specifying a display magnification (for example, 75%). If the display unit is a touch panel that supports multi-touch, changes may be accepted by operations such as pinch-out and pinch-in. Pinch out refers to an operation of placing two fingers on the screen and widening the interval between the fingers. This increases the display magnification (enlarged display). Pinch-in refers to the operation of placing two fingers on the screen and reducing the distance between them. As a result, the display magnification is reduced (reduced display).

  In step S304, the CPU 201 of the electronic book terminal 101 determines whether or not ruby has already been added to the electronic book data displayed in step 302. If the ruby has already been shaken (step S304: YES), the process proceeds to the flowchart shown in FIG. The process shown in the flowchart of FIG. 4 will be described later.

  If the ruby is not shaken (step S304: NO), the process proceeds to step S305.

  In step S305, the CPU 201 of the electronic book terminal 101 determines whether the setting relating to the ruby display accepted in step S301 is “magnification designation”. That is, in the screen of FIG. 6, “Rubi when zooming in” is checked, and it is determined whether or not “Specify magnification” is selected from the pull-down list.

  If the magnification is designated (step S305: YES), the process proceeds to step S310.

  If the magnification is not designated (step S305: NO), the process proceeds to step S306.

  In step S306, the CPU 201 of the electronic book terminal 101 determines whether the setting relating to the ruby display accepted in step S301 is “automatic”. That is, in the screen of FIG. 6, “Rubi at enlargement” is checked, and it is determined whether or not “Automatic” is selected from the pull-down list.

  If it is automatic (step S306: YES), the process proceeds to step S307.

  If not automatic (step S306: NO), the process proceeds to step S315.

  In step S <b> 307, the CPU 201 of the electronic book terminal 101 acquires the resolution of the display unit of the electronic book terminal 101.

  In step S308, the CPU 201 of the electronic book terminal 101 obtains the size between the lines of the electronic book data displayed on the display unit.

  In step S309, the CPU 201 of the electronic book terminal 101 determines whether the line spacing is sufficient for displaying ruby from the resolution acquired in step S307 and the line spacing acquired in step S308.

  Specifically, data as shown in FIG. 5 is stored in advance, and from the acquired resolution, ruby is displayed if the line spacing size is equal to or larger than a predetermined size, and if the line spacing size is equal to or smaller than a predetermined value. Judge that ruby is not displayed.

  If it is determined that the line spacing is sufficient to shake the ruby (step S309: YES), the process proceeds to step S311.

  If it is determined that the ruby is not sufficient (step S309: NO), the process proceeds to step S315.

  In step S310, the CPU 201 of the electronic book terminal 101 determines whether the current display magnification is higher than the magnification set in step S101 (whether the display is enlarged from the set magnification). If the magnification is higher than the set value (step S310: YES), the process proceeds to step S311.

  When the magnification is lower than the set value (step S310: NO), the process proceeds to step S315.

  In step S311, the CPU 201 of the electronic book terminal 101 extracts text data of electronic book data displayed on the display unit.

  In step S312, the CPU 201 of the electronic book terminal 101 passes the data extracted in step S311 and the setting value received in step 301 (ruby designation, ruby appearance, etc.) to the ruby swing program, and the ruby-wound data (ruby tag) (Text data with (additional information)) is acquired.

  In step S313, a ruby is added to the text data passed in step S312 by the ruby swing program (a ruby tag is added). Here, the ruby swing program is configured by a ruby swing program using a known technique. Further, the program may be inside the electronic book terminal 101 or may be in an external device 102 different from the electronic book terminal 101.

  In this embodiment, the program is described as a ruby-waving program. However, the present invention is not limited to ruby. For example, a program that assigns Japanese meaning to a foreign language word or a foreign language meaning to a Japanese word. Any program that adds information to display additional information with respect to the original text data, such as a program that assigns meaning to a technical term, may be used. In other words, “shake ruby” in the present embodiment is an example of adding additional information to a certain character string and displaying it.

  In step S314, the CPU 201 of the electronic book terminal 101 processes the text data with the ruby tag acquired in step S312.

  In step S315, the CPU 201 of the electronic book terminal 101 displays the electronic book data on the display unit.

  If NO is determined in step S306, NO is determined in step S309, and NO is determined in step S310, a screen on which no ruby is displayed is displayed. On the other hand, when the process of step S314 is executed, a screen on which ruby is displayed is displayed.

  Further, the processing of steps S303 to S315 shown in this flowchart is executed when an instruction to change the screen display size is received from the user.

  Next, with reference to FIG. 4, a ruby deletion process performed by the electronic book terminal 101 when it is determined YES in step S304 of the flowchart shown in FIG. 3 in the embodiment of the present invention will be described.

  Note that the processing shown in the flowchart of FIG. 4 is processing in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S401, the CPU 201 of the electronic book terminal 101 determines whether the setting relating to the ruby display accepted in step S301 is “magnification designation”. That is, in the screen of FIG. 6, “Rubi when zooming in” is checked, and it is determined whether or not “Specify magnification” is selected from the pull-down list.

  If the magnification is designated (step S401: YES), the process proceeds to step S406.

  If the magnification is not designated (step S401: NO), the process proceeds to step S402.

  In step S402, the CPU 201 of the electronic book terminal 101 determines whether the setting relating to the ruby display received in step S301 is “automatic”. That is, in the screen of FIG. 6, “Rubi at enlargement” is checked, and it is determined whether or not “Automatic” is selected from the pull-down list.

  If it is automatic (step S402: YES), the process proceeds to step S403.

  If not automatic (step S402: NO), the process proceeds to step S407.

  In step S <b> 403, the CPU 201 of the electronic book terminal 101 acquires the resolution of the display unit of the electronic book terminal 101.

  In step S404, the CPU 201 of the electronic book terminal 101 acquires the size between the lines of the electronic book data displayed on the display unit.

  In step S405, the CPU 201 of the electronic book terminal 101 determines whether the line spacing is sufficient for displaying ruby from the resolution acquired in step S403 and the line spacing acquired in step S404.

  Specifically, data as shown in FIG. 5 is stored in advance, and from the acquired resolution, ruby is displayed if the line spacing size is equal to or larger than a predetermined size, and if the line spacing size is equal to or smaller than a predetermined value. Judge that ruby is not displayed.

  If it is determined that the line spacing is sufficient to shake the ruby (step S405: YES), the process proceeds to step S409.

  If it is determined that the ruby is not sufficient (step S405: NO), the process proceeds to step S407.

  In step S406, the CPU 201 of the electronic book terminal 101 determines whether the current display magnification is higher than the magnification set in step S101 (whether the display is enlarged from the set magnification). If the magnification is higher than the set value (step S406: YES), the process proceeds to step S409.

  When the magnification is lower than the set value (step S406: NO), the process proceeds to step S407.

  In step S407, the CPU 201 of the electronic book terminal 101 extracts text data of electronic book data displayed on the display unit.

  In step S408, the CPU 201 of the electronic book terminal 101 deletes the ruby tag from the text data acquired in step S407. That is, text data that does not display ruby is created.

  In step S409, the CPU 201 of the electronic book terminal 101 displays the electronic book data on the display unit.

  Here, when it is determined YES in step S405, or when YES is determined in step S406 (that is, when the ruby is displayed at a magnification that can be displayed), the electronic book data is displayed while the ruby is displayed. Display on the display. On the other hand, when the process of step S408 is executed, the electronic book data in which the ruby is not shaken (the ruby is deleted) is displayed on the display unit.

  Through the above processing, when a reduction instruction is given to a screen on which ruby has already been shaken, it is possible to change to a screen display from which ruby has been deleted.

  FIG. 7 is a diagram illustrating an example of a screen displayed in a reduced size than the set display magnification. In the example of FIG. 7, an example of “display magnification: 75%” is shown. In the reduced display, many characters are displayed on one screen as in the screen shown in FIG. 7, and ruby is not shaken (for example, “Mari Syoten” in the row indicated by 701 in FIG. 7 Is not ruby).

  FIG. 8 is a diagram illustrating an example of a screen when an enlarged display is performed at a display magnification larger than the set display magnification. In the example of FIG. 8, an example of “display magnification: 150%” is shown. In the enlarged display, the size of one character is large and the line spacing is also widened. Therefore, the ruby is shaken and displayed (for example, “Mari-Shiten” in the row 801 in FIG. 8 is displayed with the ruby “Mariten” shaken).

As explained above, if the display size on the screen is enlarged, ruby is also displayed, and if the reader wants to know how to read it, it can be enlarged and displayed with ruby. . Further, by controlling so that ruby is not displayed when reduced display is performed, if ruby is unnecessary, it is possible to switch to display without ruby by performing reduced display.
Thus, according to the display magnification being changed by the user, it is possible to switch whether or not to display the text data (character string) together with the additional information.

  In addition, if ruby is displayed even when reduced, the ruby becomes a very small character and cannot be read. Since it can be controlled not to display such characters that cannot be read, it is possible to provide an easy-to-read display without displaying unnecessary information for the reader.

In the present embodiment, the method of using the line spacing size and the resolution and the method of using the display magnification have been described in determining whether to display ruby. In determining whether or not to display ruby, the object of the present invention can be achieved if it is possible to switch whether or not to display ruby depending on whether it can be displayed in a size that can be read. Therefore, the specific determination method is not limited to the method using the line spacing size and the resolution and the method using the display magnification described in this embodiment. For example, it may be configured to determine whether or not to display ruby by comparing the character size of the ruby to be displayed with a predetermined size.
<< Second Embodiment >>
Next, a second embodiment of the present invention will be described.

  In the description of the second embodiment, processing different from that of the above-described first embodiment will be described.

  First, a ruby swing process performed by the electronic book terminal 101 in the second embodiment of the present invention will be described with reference to FIG.

  Note that the processing shown in the flowchart of FIG. 9 is processing in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S301, the CPU 201 of the electronic book terminal 101 receives various settings from the user via the screen shown in FIG. Here, in addition to the settings accepted in the first embodiment, in the present embodiment, there are settings related to processing when ruby display cannot be performed, and settings related to regular ruby. Details of these settings will be described later.

  In addition, the individual designated character string file is read. This individually designated character string file includes information set on the screen shown in FIG. 15 and information on individually designated character strings and their ruby tags.

  For example, when “5th grade” and “6th grade” are checked in the constant ruby setting field (1501) in FIG. 15, the kanji learned by the 5th and 6th grade is processed by the process shown in FIG. Ruby will be given. It is assumed that kanji corresponding to check items that are check boxes, such as kanji learned in each grade and kanji other than educational kanji, are registered in advance.

  In step S302, the CPU 201 of the electronic book terminal 101 displays the electronic book data on the display unit. This process is the same process as step S302 in the first embodiment.

  In step S901, the CPU 201 of the electronic book terminal 101 determines whether or not the ruby setting is always set in the setting received in step S301 (whether any item in the always ruby setting column is checked). To do.

  When the ruby is always set (step S901: YES), the process proceeds to the flowchart shown in FIG. The process of the flowchart shown in FIG. 12 will be described later.

  If the ruby is not always set (step S901: NO), the process proceeds to step S903.

  In step S902, the CPU 201 of the electronic book terminal 101 determines whether an individually designated character string has been set. Specifically, the determination is made based on whether or not an individual designated character string is included in the file read in step S301. Here, the individually designated character string means a character string individually set as a character string for displaying ruby, separately from the setting via the screen shown in FIG. The setting of the individually designated character string may be registered as an individually designated character string in advance. It is also possible to register by the process shown in FIG.

  If an individually designated character string has been set (step S902: YES), the process proceeds to the flowchart shown in FIG.

  If the individually designated character string is not set (step S902: NO), the process proceeds to step S304.

  The processing in steps S304 to S315 is the same as the processing in steps S304 to S315 in the first embodiment, and thus the description thereof is omitted here.

  Note that, in the determination processing of “whether the ruby is shaken” in step S304, the ruby set in the ruby designation field 1504 is displayed on the screen of FIG. 15 instead of the ruby or the ruby of the individually designated character string. This is a process for determining whether or not there is.

  If YES in step S304, the process proceeds to the flowchart shown in step FIG.

  If NO in step S309, the process proceeds to step S903.

  In step S903, the CPU 201 of the electronic book terminal 101 determines whether or not “when ruby display cannot be performed” is set in the setting received in step S301.

  If it is set (step S903: YES), the process proceeds to the flowchart shown in FIG.

  If it has not been set (step S903: NO), the process proceeds to step S315.

  If NO in step S310, the process proceeds to step S904.

  In step S904, the CPU 201 of the electronic book terminal 101 determines whether or not “when ruby display cannot be performed” is set in the setting received in step S301.

  If it is set (step S904: YES), the process proceeds to the flowchart shown in FIG.

  If not set (step S904: NO), the process proceeds to step S315. And the process of this flowchart is complete | finished.

  Note that the processing in steps S901 to S315 in this flowchart is processing that is executed when the user gives an instruction to change the display magnification. In other words, in response to receiving an instruction to enlarge or reduce the display magnification by the user, whether to display ruby is switched.

  Next, the process shown in the flowchart of FIG. 10 will be described. Since the processing of S401 to S409 shown in the flowchart of FIG. 10 is the same as the processing shown in the flowchart of FIG. 4 in the first embodiment, description thereof is omitted here.

  If NO in S402, NO in S405, or NO in S406, the process of step S1001 is executed.

  In step S <b> 1001, the CPU 201 of the electronic book terminal 101 determines whether or not processing is set when ruby display cannot be performed.

  If it is set (step S1001: YES), the process proceeds to the flowchart shown in FIG.

  If not set (step S1001: NO), the process proceeds to step S407.

  Next, a process of registering a character string designated by the user as a character string that always gives ruby will be described using the flowchart shown in FIG.

  The process shown in the flowchart of FIG. 11 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S <b> 1101, the CPU 201 of the electronic book terminal 101 displays electronic book data on the display unit of the electronic book terminal 101.

  In step S1102, the CPU 201 of the electronic book terminal 101 accepts selection of a character string by the user.

  As a method of accepting selection of a character string, a method of accepting selection by touching a character string on the screen of the display unit by the user can be considered. Further, it may be controlled to accept the selection by continuously touching the area where the character string for which ruby is to be displayed is displayed for a certain period of time. Moreover, if it is an electronic book terminal in which a cursor is displayed, you may control so that selection using a cursor may be received. As described above, any method may be used as a method of accepting selection of a character string for displaying ruby.

  In step S1103, the CPU 201 of the electronic book terminal 101 determines whether or not to register the character string selected in step S1102 as a character string that always displays ruby.

  Specifically, it may be determined by displaying a screen for accepting the setting as to whether or not to register as a character string that always displays ruby and accepting selection by the user.

  FIG. 25 is an example of a screen in which a screen (2501) for accepting selection as to whether or not to register as a character string that always displays ruby is displayed as a pop-up.

  If “regular ruby registration” is selected, it is determined to register (YES in step S1103).

  When “Cancel” is selected, it is determined that registration is not performed (NO in step S1103).

  When registering (step S1103: YES), the process proceeds to step S1104.

  When not registering (step S1103: NO), the process of this flowchart is complete | finished.

  In step S1104, the CPU 201 of the electronic book terminal 101 acquires documents before and after the character string designated in step S1102. The reason why the previous and next documents are acquired is that it is necessary to appropriately determine how to read the kanji because the same kanji may be read differently depending on the context before and after. is there. Therefore, what is necessary is just to acquire the document before and behind in the range which can specify how to read (for example, acquiring one sentence including the said character string).

  In step S1105, the CPU 201 of the electronic book terminal 101 passes the document acquired in step S1104 to the ruby swing program, and acquires the ruby swing process (step S1106) (text with the ruby tag added to the designated character string). To do.

  Here, since the ruby swing process is the same process as the process of step S313 in the first embodiment, a description thereof is omitted here.

In step S1107, the CPU 201 of the electronic book terminal 101 converts the individually designated character string (the character string selected by the user in step S1102) and the ruby tag attached to the character string into the individually designated character string file (in step S301). Save to (File to be read).
Then, the process proceeds to the flowchart shown in FIG.

  Next, with reference to FIG. 12, a process when the ruby is always set (when YES in step S901 in FIG. 9) will be described.

  The process shown in the flowchart of FIG. 12 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  Steps S403 to S404 are the same as the corresponding processes in the first embodiment, and a description thereof is omitted here.

  In step S405, the CPU 201 of the electronic book terminal 101 determines whether ruby can be displayed using the resolution acquired in step S403 and the line spacing acquired in step S404.

  Here, the criterion for determining whether or not ruby can be displayed is a milder condition than the criterion used in the first embodiment and the criterion used in step S309 in FIG. 9 (for example, FIG. 5). That is, the character string set as always ruby is displayed even if it is smaller than normal ruby.

  For example, instead of FIG. 5, a data table as shown in FIG. 23 is stored, and for the character string to which ruby is always added or the individually designated character string, the ruby display is always performed using the ruby standard (2302). For character strings that switch non-display and add normal ruby, display / non-display of ruby is switched using the normal ruby standard (2301).

  If it is determined that ruby can be displayed (step S405: YES), ruby is displayed for the character string that displays ruby, and the process proceeds to step S409. Here, in the process of displaying ruby, as in step S1106 and the like, the electronic book data is passed to the ruby swing program and the ruby swing process is executed.

  If ruby cannot be displayed (step S405: No), the process proceeds to step S1201.

  In step S <b> 1201, the CPU 201 of the electronic book terminal 101 determines whether or not processing is set when ruby display cannot be performed.

  If it is set (step S1201: YES), the process proceeds to the flowchart shown in FIG.

  If not set (step S1201: NO), the process proceeds to step S407.

  The processing in steps S407, S408, and S409 is the same as the corresponding processing in the first embodiment, and thus description thereof is omitted here.

  When the electronic book data is displayed in step S409, the processing of this flowchart ends. When the process of this flowchart is completed, the process proceeds to step S902 in FIG.

  Next, a process for applying ruby to a designated character string will be described with reference to FIG.

  The process shown in the flowchart of FIG. 13 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S1301, the CPU 201 of the electronic book terminal 101 searches the electronic book data for the same character string as the character string specified in step S1102. If YES in step S902, a character string that is the same as the character string to be processed is retrieved from the character strings in the individually designated character string file read in step S301.

  In step S1302, the CPU 201 of the electronic book terminal 101 gives a ruby tag to the character string searched in step S1301.

  That is, it is a process for adding ruby to the character string designated in step S1102 or the same character string registered in the individually designated character string file in the electronic book data.

  In step S1303, the CPU 201 of the electronic book terminal 101 acquires the individually designated character string in the individually designated character string file.

  In step S1304, the CPU 201 of the electronic book terminal 101 determines whether the individual designated character string to be processed is the last individual designated character string. That is, it is determined in step S1303 whether an individually designated character string has been acquired.

  If it is the last individually designated character string (step S1304: YES), the process proceeds to step S403.

  If it is not the last individually designated character string (step S1304: NO), the process proceeds to step S1305.

  In step S1305, the CPU 201 of the electronic book terminal 101 acquires the next individual designated character string included in the read individual designated character string file, and the process proceeds to step S1301.

  In step S <b> 403, the CPU 201 of the electronic book terminal 101 acquires the resolution of the display unit of the electronic book terminal 101.

  In step S404, the CPU 201 of the electronic book terminal 101 acquires the size between the lines of the electronic book data displayed on the display unit.

  In step S405, the CPU 201 of the electronic book terminal 101 determines whether the line spacing is sufficient for displaying ruby from the resolution acquired in step S403 and the line spacing size acquired in step S404.

  Specifically, data as shown in FIG. 5 is stored in advance, and from the acquired resolution, ruby is displayed if the line spacing size is equal to or larger than a predetermined size, and if the line spacing size is equal to or smaller than a predetermined value. Judge that ruby is not displayed.

  If it is determined that the line spacing is sufficient to display ruby (step S405: YES), the process proceeds to step S409.

  If it is determined that the line spacing is not sufficient to display ruby (step S405: NO), the process proceeds to step S1306.

  In step S <b> 1306, the CPU 201 of the electronic book terminal 101 determines whether the process “when ruby display cannot be performed” is set.

  If the setting has been made (step S1306: YES), the process proceeds to the flowchart shown in FIG.

  If it is not set (step S1306: NO), the process proceeds to step S1307.

  In step S1307, the CPU 201 of the electronic book terminal 101 extracts the text of the electronic book data displayed on the display unit.

  In step S1308, the CPU 201 of the electronic book terminal 101 deletes the ruby tag attached to the text extracted in step S1307.

  Then, the process proceeds to step S409, and electronic book data (data with ruby or data with ruby deleted) is displayed on the display unit of the electronic book terminal 101.

  Then, the process shown in this flowchart is terminated. When the process of the flowchart is completed, the process proceeds to step S304 in FIG.

  Next, the processing when ruby cannot be displayed will be described with reference to FIG.

  The process shown in the flowchart of FIG. 14 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S1401, the CPU 201 of the electronic book terminal 101 acquires setting information. Here, the setting information includes settings related to display control when ruby cannot be displayed. For example, “If you cannot display ruby, draw a side line for the kanji to which ruby is attached” or “If the ruby cannot be displayed, color the kanji to which ruby is added. Settings such as “display” are included. In this way, when ruby cannot be displayed, display control may be performed so that kanji to which ruby is added (ruby is shaken) can be distinguished from other characters.

  In step S1402, the CPU 201 of the electronic book terminal 101 executes processing based on the setting acquired in step S1401.

  Specific examples of the processing in step S1402 include, for example, a process for displaying a character string to which ruby is shaken, a process for adding a ruled line (side line) to a character string to which ruby is shaken, and a character string to which ruby is shaken. Processing that reverses black and white can be considered. In other words, any method may be used as long as the display allows the user to recognize that the character string is a ruby character.

  In step S1403, the CPU 201 of the electronic book terminal 101 displays the electronic book data on which the process of step S1402 has been performed on the display unit.

  FIGS. 16, 17, and 22 are diagrams illustrating examples of screens displayed in step S1403.

  FIG. 16 is a diagram illustrating an example of a screen when a ruled line (side line) is added to a character string to which ruby is shaken. For example, “Mari-Shiten” in the row 1601 is not a ruby “Marishen” but a side line.

  FIG. 17 is a diagram illustrating an example of a screen when a character string to which ruby is shaken is reversed in black and white. For example, the character string “Mari-Shiten” in the row 1701 is reversed in black and white.

  In FIG. 22, “Mari-Shiten” is a character string set as an individually designated character string (or always ruby), and the rest are normal ruby character strings. In addition, the display magnification indicates a case where the individually designated character string and the regular ruby are displayed, but the normal ruby character string is not displayed.

In the row indicated by 2201 in FIG. 22, a ruby “Marishin” is given to the character string “Mari Shokuten”. On the other hand, the ruby is not shaken on the “desk” in the row indicated by 2202, and instead, a side line, which is a process when the ruby cannot be displayed, is added.
Then, the process proceeds to the flowchart shown in FIG.

  FIG. 19 is a process of displaying ruby on a character by selecting a ruby-designated character by the user when the process of step S1402 is performed.

  Note that the process shown in the flowchart of FIG. 19 is a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S1901, the CPU 201 of the electronic book terminal 101 accepts selection of a ruby designated character from the user. As a method of accepting the selection of the character string here, as described in step S1102, a method of accepting the selection by touching the character string on the screen of the display unit by the user can be considered. Further, it may be controlled to accept the selection by continuously touching the area where the character string for which ruby is to be displayed is displayed for a certain period of time. Moreover, if it is an electronic book terminal in which a cursor is displayed, you may control so that selection using a cursor may be received. As described above, any method may be used as a method of accepting selection of a character string for displaying ruby.

  In step S1901, when a selection of a character string is received from the user, a screen as shown in FIG. 24 is displayed.

  As shown in FIG. 24, a screen for selecting whether or not to display ruby corresponding to the character string selected by pop-up or the like is displayed (2401). In the example of FIG. 24, if “ruby display” 2401 is selected, the process proceeds to step S1902. On the other hand, if “cancel” is selected, the pop-up screen is terminated and the processing of this flowchart is terminated.

  In step S1902, the CPU 201 of the electronic book terminal 101 acquires documents before and after the character string designated in step S1901. The reason why the previous and next documents are acquired is that it is necessary to appropriately determine how to read the kanji because the same kanji may be read differently depending on the context before and after. is there. Therefore, what is necessary is just to acquire the document before and behind in the range which can specify how to read (for example, acquiring one sentence including the said character string).

  In step S1903, the CPU 201 of the electronic book terminal 101 passes the document acquired in step S1902 to the ruby swing program, and acquires the document (text with the ruby tag added to the designated character string) that has been subjected to the ruby swing process (step S1904). To do.

  Here, since the ruby swing process is the same process as the process of step S313 in the first embodiment, a description thereof is omitted here.

  In step S1905, the CPU 201 of the electronic book terminal 101 processes the text data with the ruby tag acquired in step S1903.

  In step S1906, the CPU 201 of the electronic book terminal 101 displays a screen in which ruby is added to the character string selected in step S1901 on the display unit.

  An example of the screen displayed in step S1906 is shown in FIG. In the screen shown in FIG. 18, an example in which “Mari Shuten” is selected is shown.

  As shown in FIG. 18, a ruby “Mariten” is displayed by a balloon for the selected character string “Mari-Shiten”.

  As described above, ruby that is always displayed and even if it is a small character is displayed for ruby of individually designated character strings, and ruby that is displayed in stages, such as displaying normal ruby with a predetermined size. Can be set.

  For example, if everything from elementary school 1st to 6th grade is set as normal ruby, and 5th and 6th grades are always set as ruby, 5th and 6th grade rubies may not have line spacing or display magnification Is displayed even when the line spacing is low, and ruby corresponding to 1 to 4 years is displayed when the line spacing is wider or when the display magnification is higher.

In addition, ruby can be temporarily displayed for the character string selected by the user.
<Third Embodiment>
Next, a third embodiment will be described with reference to FIG.

  In the third embodiment, the character string set as “always ruby” and the individually designated character string are configured to always display ruby regardless of the line spacing, the display magnification, and the like.

  FIG. 21 shows a process in which the CPU 201 of the electronic book terminal 101 reads and executes a predetermined control program.

  In step S2101, the CPU 201 of the electronic book terminal 101 accepts a change in display magnification in response to an instruction from the user.

  The method for accepting the change in display magnification may be accepted by the user specifying a display magnification (for example, 75%). If the display unit is a touch panel that supports multi-touch, changes may be accepted by operations such as pinch-out and pinch-in. Pinch out refers to an operation of placing two fingers on the screen and widening the interval between the fingers. This increases the display magnification (enlarged display). Pinch-in refers to the operation of placing two fingers on the screen and reducing the distance between them. As a result, the display magnification is reduced (reduced display).

  In step S2102, the CPU 201 of the electronic book terminal 101 determines whether there is a constant ruby setting. Specifically, the determination is made based on whether or not the setting read in step S301 includes a constant ruby setting. The determination process here is the same as the process of step S901.

  When the ruby is always set (step S2102: YES), the process proceeds to step S2103.

  If ruby is not always set (step S2102: NO), the process proceeds to step S2104.

  In step S <b> 2103, the CPU 201 of the electronic book terminal 101 displays ruby for a character string that is set to be always displayed as ruby. Specifically, the electronic book data is transferred to the ruby swing program and displayed based on the ruby tag given by the ruby swing program.

  In step S2103, regardless of the line spacing, display magnification, etc., ruby is displayed for all character strings set to be displayed as ruby all the time. Here, since the line spacing size is small, if the ruby becomes so small that it is difficult to read, a space for displaying the ruby is secured as shown in the line 2001 in FIG. ) Shake ruby. Also, a balloon may be displayed as indicated by line 1801 in FIG. 18, and ruby may be displayed there.

  In step S2104, the CPU 201 of the electronic book terminal 101 determines whether an individually designated character string is set. The individually designated character string means a character string registered as a character string for individually displaying ruby as described above.

  If an individually designated character string is set (step S2104: YES), the process proceeds to step S2105.

  If the individually designated character string is not set (step S2104: NO), the process proceeds to step S2106.

  Whether or not the individually designated character string is set is determined by whether or not the individually designated character string is included in the file read in step S301.

  In step S2105, the CPU 201 of the electronic book terminal 101 displays the ruby of the individually designated character string. The processing in step S2105 is the same as the processing in steps S1104 to S1106.

  In step S2106, the CPU 201 of the electronic book terminal 101 determines whether or not to display normal ruby. The normal ruby means ruby that is not always ruby or ruby of an individually designated character string. That is, the ruby set in the ruby designation field 1504 in FIG.

  Whether or not to display ruby is the same as the determination in the first and second embodiments (steps S305 to S310), and determination based on the line spacing size and resolution, determination based on the display magnification, and the like are conceivable.

  If ruby display is to be performed (step S2106: YES), the process proceeds to step S2107.

  If ruby is not displayed (step S2106: NO), the process proceeds to step S2108.

  In step S2107, the CPU 201 of the electronic book terminal 101 displays ruby. The ruby display process here is realized by passing the electronic book data to the ruby swing program in the same manner as the processes in the first embodiment and the second embodiment.

  In step S <b> 2108, the CPU 201 of the electronic book terminal 101 determines whether or not processing is set when ruby display cannot be performed. Specifically, in the screen shown in FIG. 15, when the ruby display cannot be performed (1502), the determination is made based on whether or not the check is made.

  If it has been set (step S2108: YES), the process proceeds to step S2109.

  If no setting has been made (step S2108: NO), the processing of this flowchart is terminated.

In step S <b> 2109, the CPU 201 of the electronic book terminal 101 executes processing when ruby display cannot be performed. Specifically, similarly to steps S1401 and S1402, processing is executed according to the processing content (1503) selected via the screen of FIG.
Then, the process shown in this flowchart is terminated.

  As described above, the processing described in this flowchart is executed when the user gives an instruction to change the screen display size (display magnification).

  In addition, when the process of step S2109 is executed, as shown in FIG. 19, the selection of the character string to which the ruby tag is attached is received to display the ruby attached to the selected character string. It is possible to execute processing.
