Description

  The present invention relates to a sentence display device, a sentence display method, a sentence display program, and a computer-readable recording medium.

  As a conventional first sentence display device, there is a device that prints a horizontally written character that is a 2-byte character (Japanese) by simply rotating it 90 degrees (for example, Japanese Patent Application Laid-Open No. 2002-273934 (Patent Document 1). )reference). However, in the first sentence display device, the positions of ““ ”,“ ””, “,”, etc. become unnatural simply by arranging full-width characters in the vertical direction without rotating.

  In addition, as a conventional second sentence display device, a table that stores a shift amount or the like at the time of vertical writing according to a character code is held, and by performing rotation and movement by the amount described in the table, it can be used for horizontal writing. Some fonts are used in vertical writing (see, for example, JP-A-2001-134257 (Patent Document 2)).

  In the second sentence display device, when the shift amount is defined, it is necessary to hold a table for each type of font, and it is necessary to hold a table for each font size in advance. It is not practical to apply to fonts with multi-level font sizes. Currently, more fonts are added by downloading, etc., and the shift process in the table created in advance allows beautiful display of the initial font, but when applied to the added font, the table for the added font Is required, and a process for newly adding the table is required.

  Further, as a conventional third sentence display device, there is one that generates a display of a vertical writing (horizontal writing) layout from a horizontal writing (vertical writing) screen recognized from an image (for example, Japanese Patent Application Laid-Open No. 2010-129023). See Patent Document 3)). In the third sentence display device, the rotation of the character (font) changes the process according to the condition, and the character according to the condition such as the character recognition result, the image character area recognition (position and ratio of the character area), etc. Rotate and shift the image. Further, the character images are grouped based on the rules based on the information such as the arrangement positions of the images.

  However, in the third sentence display device, it is difficult to apply a predetermined classification rule to fonts of various designs, and it is necessary to define rules in detail for each font. In the third sentence display device, monospaced fonts are handled, but currently there are few monospaced fonts, and in the case of proportional fonts with different character widths, the intended display cannot be made and half-width full-width characters are mixed. There is a problem that proper layout cannot be made for simple characters.

FIG. 1 shows a block diagram of a text display device for displaying text of an electronic book according to the first embodiment of the present invention. Note that this text display device includes a font data storage unit (not shown) having horizontal writing font data including a character image corresponding to a character code.

  As shown in FIG. 1, the text display device according to the first embodiment lays out a book data acquisition unit 1 that acquires data of an electronic book, and analyzes the data of the electronic book acquired by the book data acquisition unit 1. Whether or not the character image needs to be rotated / shifted based on the layout generation unit 2 that determines the layout, layout information representing the layout determined by the layout generation unit 2, and the arrangement condition table stored in the arrangement condition table storage unit 11. A character rotation / shift determination unit 3 for determining whether or not, a processing content determination unit 4 for determining the processing content of the character image based on the arrangement condition table stored in the arrangement condition table storage unit 11, and a reference character. The reference position is determined based on the reference character acquisition unit 5 to be acquired and a rectangular frame circumscribing the character image of the reference character acquired by the reference character acquisition unit 5. A reference position determination unit 6 to be determined, and a character image conversion unit for determining a moving position of the character image based on the reference position determined by the reference position determination unit 6 and the shift position rule stored in the shift position rule storage unit 12 As an example, the moving position determining unit 7, the character image whose moving position is determined by the moving position determining unit 7, and the character image of the character that is determined not to be rotated / shifted by the character rotation / shift determining unit 3, A character image arrangement unit 8 arranged in an image memory (not shown) for one page based on layout information, an image output unit 9 for outputting image data in which a character image is arranged by the character image arrangement unit 8, and an image And a display unit 10 for displaying the image data output from the output unit 9. The display unit 10 displays the text of the electronic book in vertical writing or horizontal writing.

  2 and 3 are flowcharts for explaining the operation of the sentence display device. Note that this flowchart is a process of displaying one page of the electronic book on the display unit 10, and this display process is repeated when there is a page feed (or return).

  First, when this process starts, the book data acquisition unit 1 acquires electronic book data in step S1 shown in FIG.

  In step S2, the electronic book data is analyzed by the layout generation unit 2 and the book data information of the display page necessary for the layout is held.

  In step S3, the layout generation unit 2 determines the layout of the image and text based on the book data information and the display setting of the display unit 10. Here, the layout generation unit 2 generates layout information necessary for the layout. Here, the layout information is information related to the arrangement of elements composed of characters, images, multimedia data, and the like.

  Next, it progresses to step S4 and it is determined whether the text of an electronic book is vertical writing or horizontal writing from layout information.

  If it is determined in step S4 that the text of the electronic book is not vertically written, the process proceeds to step S5, where the character rotation / shift determination unit 3 obtains one line of layout information from the layout generation unit 2.

  In step S6, the character rotation / shift determination unit 3 acquires a character code from the layout generation unit 2.

  In step S7, the character image placement unit 8 places a character image corresponding to the character code in an image memory (not shown).

  Next, the process proceeds to step S8, and if it is determined that the arrangement of one line is not completed, the process returns to step S6, whereas if it is determined that the arrangement of one line is completed, the process proceeds to step S9.

  Next, when it is determined in step S9 that the arrangement of all the rows has not been completed, the process proceeds to step S11, the line is advanced, and the process returns to step S5.

  On the other hand, if it is determined in step S9 that the arrangement of all lines has been completed, the process proceeds to step S10, where the image output unit 9 outputs the image data in which the character image is arranged by the character image arrangement unit 8 to the display unit 10. This display process is terminated.

  If it is determined in step S4 that the writing is vertical, the process proceeds to step S21 shown in FIG.

  In step S21, the reference character acquisition unit 5 acquires a reference character. In the first embodiment, “country” (Unicode 0x56fd) is acquired as a reference character.

  In step S22, the reference position determination unit 6 determines a reference position based on a rectangular frame circumscribing the character image of the reference character. In the first embodiment, a rectangular frame circumscribing the character image of “country” is arranged so that the center coincides with the center of the virtual body and is set as a reference position. Here, the virtual body is a “frame for drawing characters” specified from the layout. Actually, the character width obtained from the font information by specifying the height of the character and the height of the character This is a rectangular drawing area consisting of The layout is an arrangement in which lines are generated by aligning characters with the center of the rectangular drawing area aligned.

  Next, in step S <b> 23, the character rotation / shift determination unit 3 acquires one line of layout information from the layout generation unit 2.

  In step S24, the character rotation / shift determination unit 3 acquires a character code from the layout generation unit 2.

  In step S25, the character rotation / shift determination unit 3 determines whether rotation / shift is necessary for the character code acquired in step S24. That is, it is determined whether or not rotation / shift is necessary for the acquired character code using a preset character code table. Here, the preset character code table is stored in the arrangement condition table storage unit 11 as an arrangement condition table (shown in FIGS. 4 and 5).

  If it is determined in step S25 that rotation / shift is necessary for the acquired character code, the process proceeds to step S26, while if it is determined that rotation / shift is not required for the acquired character code, the process proceeds to step S29. move on.

  In step S26, a process ID corresponding to the character code acquired from the arrangement condition table storage unit 11 is acquired.

  Next, it progresses to step S27 and the process content determination part 4 determines a process content based on acquired process ID.

  Next, the process proceeds to step S28, and the movement position is determined by the movement position determination unit 7. That is, the movement position determination unit 7 performs at least one of rotation and movement of the character image according to the processing content determined in step S27, using the reference position determined in step S22.

  In step S29, the character image placement unit 8 places a character image corresponding to the character code in an image memory (not shown). In step S29, for the character code determined to require rotation / shift with respect to the acquired character code, the character image arranged in the movement position in step S28 is arranged in the image memory.

  Next, the process proceeds to step S30, and if it is determined that the arrangement of one line is not completed, the process returns to step S24, whereas if it is determined that the arrangement of one line is completed, the process proceeds to step S31.

  Next, when it is determined in step S31 that the arrangement of all the rows has not been completed, the process proceeds to step S33, the line is advanced, and the process returns to step S23.

  On the other hand, if it is determined in step S31 that the arrangement of all lines has been completed, the process proceeds to step S32, and the image data in which the character image is arranged by the character image arrangement unit 8 is output from the image output unit 9 to the display unit 10. This display process is terminated.

  The process content determination unit 4 uses the arrangement condition table stored in the arrangement condition table storage unit 11 to determine the process content from the process ID corresponding to the character code. The arrangement condition table stored in the arrangement condition table storage unit 11 summarizes the vertical writing operations corresponding to the horizontal writing character codes (hexadecimal) shown in FIGS. 31 to 33 as tables shown in FIGS. Is.

  Specifically, when the process ID is “1”, the character image such as parentheses, arrows, and academic symbols is rotated 90 degrees (clockwise). Here, the character image is rotated 90 degrees (clockwise) around the center of the virtual body, that is, the intersection of the diagonal lines of the rectangular virtual body.

  Further, when the process ID is “2”, the character image such as a long sound symbol is rotated 90 degrees (clockwise) and reversed left and right. Here, the horizontal reversal of the character image is performed with respect to the center line of the character image. The left-right inversion of the character image is not limited to this, and may be performed on a vertical straight line passing through the intersection of the center line of the virtual body, that is, the diagonal line of the rectangular virtual body.

  When the process ID is “3”, the character image is shifted to the upper right (small movement amount).

  When the process ID is “4”, the character image is shifted to the upper right (large movement amount).

  When the process ID is “5”, the character image is shifted to the lower right.

  Further, when the process ID is “6”, the character image is rotated 180 degrees and is shifted to the upper left. Here, the rotation of the character image by 180 degrees (clockwise) is performed around the intersection of diagonal lines of the virtual body, that is, the rectangular virtual body.

  When the process ID is “7”, the character image is rotated 90 degrees (clockwise) and shifted to the left.

  Further, when the process ID is “8”, the character image is rotated 90 degrees (clockwise) and shifted to the right.

  Further, the movement position determination unit 7 determines the movement position of the character image corresponding to the process ID, using the shift position rule stored in the shift position rule storage unit 12 shown in FIG.

  FIG. 6 is a diagram for explaining the reference position of the designated character. In the first embodiment, the left reference position and the right reference position of the rectangular frame circumscribing the character image of “country” within the character size range (“virtual body”) of the designated character “country” font. The width of the rectangular frame is calculated from the height, the height of the rectangular frame is calculated from the upper reference position and the lower reference position of the rectangular frame, and the rectangular frame of this width and height is arranged so that the center coincides with the center of the virtual body.

The obtained rectangular frame is obtained, and the obtained rectangular frame is arranged so that the center coincides with the center of the virtual body, and is set as a reference position.

  Next, the movement position determination unit 7 as an example of the character image conversion unit performs a character image based on the reference position determined by the average reference position determination unit 106 and the shift position rule stored in the shift position rule storage unit 12. The movement position of the character image is determined by performing at least one of rotation or movement of the character image.

  FIG. 22 is a diagram for explaining a method of obtaining the average reference position from all characters belonging to the font of the electronic book. As shown in FIG. 22, the number of all characters belonging to the font is N, the width of each character image is w1, w2, w3,..., WN, and the height is h1, h2, h3,.

  Then, an average width w (= (w 1 + w 2 + w 3 +... + WN) / N) and an average height h (= (h 1 + h 2 + h 3 +... + HN) / N) for each character image, and a rectangular frame having a width w and a height h. Arrange the center of the virtual body to coincide with the center of the virtual body and set it as the reference position.

By determining, an appropriate reference position can be obtained for each line, so that a character image can be arranged at an optimal position for each line displayed on the display unit 10.

[Fifth Embodiment]
FIG. 26 shows a block diagram of a text display device for displaying text of an electronic book according to the fifth embodiment of the present invention. The sentence display device according to the fifth embodiment has the same configuration as the sentence display device according to the fourth embodiment except for the in-line maximum character acquisition unit 405, and the same reference numerals are given to the same components. Description is omitted.

  The in-line maximum character acquisition unit 405 acquires a character having a maximum size of a circumscribed rectangular frame among a plurality of characters included in the line to be displayed on the display unit 10.

On the other hand, the largest rectangular frame out of a plurality of rectangular frames circumscribing each other is arranged so that the center coincides with the center of the drawing area and is used as a reference position, so that the position is converted by the movement position determination unit 7 in that line. It is possible to ensure that the character image is always included in the reference position.

[Sixth Embodiment]
FIG. 27 shows a block diagram of a text display device for displaying text of an electronic book according to the sixth embodiment of the present invention. The text display device of the sixth embodiment has the same configuration as the text display device of the first embodiment except for the reference character selection unit 401 and the designated character acquisition unit 402, and the same reference numerals are used for the same components. The description is omitted.

  The reference character selection unit 501 selects, based on the shift condition information, whether the previous character is used as a reference or the next character is used as a reference. The selection criterion of the reference character selection unit 501 is that the character under the target character is selected when the shift condition uses the lower reference position, and the character under the target character is selected when the shift condition uses the upper reference position. If a character is selected and the shift condition uses only the right reference position, the lower character is selected. If the shift condition uses only the left reference position, the upper character is selected. However, if there is no character on either the upper side or the lower side, the existing character is used, and if both are not present, a fixed character (for example, a garbled symbol “)”) is used.

  The designated character acquisition unit 502 acquires a character image of the character selected by the reference character selection unit 501.

  Next, the reference position determination unit 6 determines a reference position based on a rectangular frame that circumscribes the character image of the character acquired by the designated character acquisition unit 502.

  Next, the movement position determination unit 7 as an example of the character image conversion unit performs the character image conversion based on the reference position determined by the reference position determination unit 6 and the shift position rule stored in the shift position rule storage unit 12. At least one of rotation and movement is performed to determine the moving position of the character image.

  Hereinafter, this text display device performs the same operation as the text display device of the first embodiment.

  The sentence display device of the sixth embodiment has the same effect as the sentence display device of the first embodiment.

  Moreover, according to the said text display apparatus, for every character displayed on the display part 10 of the text of an electronic book, the reference | standard position determination part 6 makes a reference | standard by the reference position determination part 6 by making one of the characters before and behind the character into a reference | standard By determining the position, the character image can be arranged at a position that is locally balanced with at least the preceding or following character. Basically, the front and rear characters are also arranged in a balanced manner. As a result, it is possible to arrange the characters in a balanced manner as a whole.

  In the first to sixth embodiments, each time an electronic book is displayed, the reference position is determined based on a rectangular frame circumscribing the character image of the reference character among all characters belonging to the font of the sentence. However, a reference position storage unit that stores the reference position determined by the reference position determination unit in association with the font and the size of the font may be provided. In this case, with respect to the same font and the same size next, by using the reference position stored in the reference position storage unit, there is no need to determine the reference position by the reference position determination unit, and the process of determining the reference position Can be simplified.

  For other sizes of the font that are the same as the font whose reference position is stored in the reference position storage unit and whose reference position is not stored in the reference position storage unit, the reference position is stored in the reference position storage unit. Based on the ratio of the size of the drawing area per character in the size of the stored font and the drawing area per character in the other sizes of the font, the reference position determination unit stores the drawing area in the reference position storage unit. By enlarging or reducing the reference position, it is not necessary to obtain a rectangular frame circumscribing the character image of the reference character by the reference position determination unit, and the process for determining the reference position can be simplified.

  For example, as shown in FIG. 28, in the calculated position information, the coordinates of the upper left corner of the virtual body are x = 0, y = 0, the coordinates of the left reference position are x1, and the coordinates of the right reference position are the x2 upper reference. The coordinates of the position are stored as y1, and the coordinates of the lower reference position are stored as y2, and when the font size is changed (= virtual body size is changed), the reference position of each font size can be determined by enlarging or reducing it according to the ratio. Calculate (enlarged to 150% in FIG. 28).

  As a result, even if the font is the same font as the font whose reference position is stored in the reference position storage unit and has a different size, the reference position can be set at high speed without recalculation. Also, when the electronic book is first opened, the reference position is calculated only once and stored in the same font by storing the reference position as data in the coordinate format as described above in association with the font name. If so, the reference positions for different sizes can be calculated at high speed.

  For example, the reference position calculated for the standard sizes of all types of fonts is stored in the reference position storage unit, and the reference position stored in the reference position storage unit at the time of the size change is enlarged or reduced to use the reference position. The calculation of the position can be greatly simplified.

  The acquisition of the reference position does not need to be determined when the electronic book is opened for the first time. If there is data stored when the reference position is acquired, the stored data is used to acquire the reference position. If there is not, the reference position can be calculated efficiently by performing calculation and storage processing.

  In the first to sixth embodiments, the width of the rectangular frame is obtained from the left reference position and the right reference position of the rectangular frame that circumscribes the character image of the reference character, and the upper reference position and the lower reference position of the rectangular frame The height of the rectangular frame is calculated from this, and the rectangular frame of this width and height is placed so that the center coincides with the center of the virtual body, and is used as the reference position. The arrangement of the rectangular frame at the average reference position in the “virtual body” may be determined by averaging the coordinates of the reference position, the upper reference position, and the lower reference position.

  For example, when the font itself is biased to the left, as shown in FIG. 29, at the position where the opening and closing of the brackets ““ ”are rotated and moved, the rectangular frame is arranged so that the center coincides with the center of the virtual body. If the reference position is used, the balance in vertical writing will be poor. In contrast, the lower left corner of the “virtual body” is the coordinate reference point, the horizontal axis x, the vertical axis y, the left reference position of each reference character, the average of the x coordinates of the right reference position and the upper reference position, By using a rectangular frame defined by the average of the y-coordinates of the reference position as the average reference position, as shown in FIG. 30, vertical writing display with a well-balanced layout as a whole can be performed using horizontal writing fonts.

  In the first to sixth embodiments, the sentence display device that displays the text of the electronic book has been described. However, the present invention is not limited to this, and the text display apparatus that displays the text of another document such as an e-mail or a document can be used. You may apply this invention.

  In the first to sixth embodiments described above, the sentence display device that vertically displays a sentence in a horizontal writing font has been described. However, the present invention is not limited to this, and the sentence display apparatus that horizontally displays a sentence in a vertical writing font. The invention may be applied. In this case, horizontal writing with a well-balanced layout as a whole can be performed using vertical writing fonts.

  Moreover, although the said 1st-6th embodiment demonstrated the text display apparatus which displays the data of the electronic book in which the text was comprised by one type of font, it is not restricted to this, A text can be written in multiple types of font. You may apply this invention to the text display apparatus which displays the text of the comprised electronic book. For example, a reference position may be determined based on a rectangular frame circumscribing a character image of a reference character for a font having a larger number of characters among all fonts used in an electronic book. .
