Description

  The present invention relates to an information processing apparatus and an information processing program.

There is an electronic document format that can describe an electronic document. For example, there is what is called PDF (Portable Document Format) (registered trademark).
In this electronic document format, fonts of characters used in the electronic document can be registered. A font is a typeface of a character used for printing or screen display. The font has a dot matrix font having a character shape as a dot and a character outline as information depending on a character drawing method. Classified as outline font. In this specification, the font may be either a dot matrix font or an outline font.

  As a technology related to this, for example, Patent Document 1 aims to reduce the amount of font data and reduce the replacement time. For example, horizontal writing font data is used as a base, and this is used for vertical writing. From the character pattern data of the font data, only those not included for horizontal writing are extracted, and a second table is generated by attaching an identifier to each character pattern of the unified font data. Separately, a first table for defining the relationship between the identifier and the character code is generated separately for horizontal writing and vertical writing. For example, when a horizontal character pattern is requested, the character code related to the request is selected as a keyword. And the corresponding identifier is read from the first horizontal writing table, and this is used as a keyword, and the corresponding horizontal writing character pattern is read from the second corresponding table. It is disclosed that read from.

In addition, for example, in Patent Document 2, when a keyboard is operated and a predetermined key is input for the purpose of quickly displaying an input character in a vertical direction or a horizontal direction, The processing unit recognizes the corresponding character code, reads the corresponding font from the font file stored in the storage unit, and displays it on the display unit. A font file consists of a font corresponding to Kanji and a vertical writing font and horizontal writing font corresponding to other characters, and the position of each font on the font file can be obtained by simple calculation. It is disclosed that high-speed access is possible.

By the way, it may be required to register font information in an electronic document. In such a case, it is not possible to deal with a document in which vertical writing and horizontal writing are mixed by simply sharing the font for vertical writing and the font for horizontal writing.
An object of the present invention is to provide an information processing apparatus and an information processing program that can solve such a problem.

The gist of the present invention for achieving the object lies in the inventions of the following items.
According to the first aspect of the present invention, a receiving unit that receives a shared font in which the character shape is the same font for horizontal writing and vertical writing, and information that can refer to the font received by the receiving unit as a vertical writing font is provided. and vertical writing information adding unit, a font that has been accepted by the accepting means, and the horizontal writing information providing means for providing information that can be referred to as font horizontal writing, as the font for vertical writing for the font that is accepted by said accepting means Font information generating means for generating font information to which information that can be referred to and information that can be referred to as a horizontal writing font is generated, and the font information generated by the font information generating means is registered in the electronic document, and for each character, Information that can be referred to as a vertical font or a horizontal font Registration means for registering any one of the possible information, the position of the character, and the size of the character for each character in the electronic document, the registration means being referred to as a vertical writing font Information that can be referred to as a vertical writing font at the time of change without registration if the same information in the same position in the character position and the character size continues. Alternatively , the information processing apparatus is characterized in that any one of information that can be referred to as a horizontal writing font, a character position, and a character size are registered as information for forming an electronic document .

The invention according to claim 2 is the information processing apparatus according to claim 1, wherein the registration unit registers each character in the electronic document including the color of the character .

According to a third aspect of the present invention, representative character generation means for generating representative characters representing a plurality of characters, and the common font information generation means accepts the representative characters generated by the representative character generation means as a shared font. The information processing apparatus according to claim 1, wherein the information processing apparatus is an information processing apparatus.

According to a fourth aspect of the present invention, the computer accepts a shared font whose character shape is the same font for horizontal writing and vertical writing, and information for referring to the font received by the receiving means as a vertical writing font. and vertical writing information assigning means for assigning, the font that has been accepted by the accepting means, and the horizontal writing information providing means for providing information that can be referred to as font horizontal writing, for the font that is accepted by said accepting means vertical A font information generating means for generating font information to which information that can be referred to as a font for use and information that can be referred to as a font for horizontal writing is added; and the font information generated by the font information generating means is registered in an electronic document; Information that can be referred to as a vertical font or horizontal writing Any one of the information that can be referred to as a character, the position of the character, and the size of the character function as registration means for registering each character in the electronic document, and the registration means Information that can be referred to as a font for writing or information that can be referred to as a font for horizontal writing, and if the same character position and character size continue, it is not registered, and the font for vertical writing when changed An information processing program that registers information that can be referred to as an image or information that can be referred to as a horizontal font, a character position, and a character size as information for constituting an electronic document. .

  According to the information processing apparatus of claim 1, when it is required to register the font information in the electronic document, the font information is reduced by sharing the font for vertical writing and the font for horizontal writing. Thus, it is possible to deal with a document in which vertical writing and horizontal writing are mixed.

  According to the information processing apparatus of the second aspect, it is possible to configure a document in which vertical writing and horizontal writing are mixed.

According to the information processing apparatus of claim 3 , font information can be further reduced.

According to the information processing program of claim 4 , when it is required to register font information in an electronic document, a vertical writing font and a horizontal writing font are shared, and vertical writing and horizontal writing are mixed. It is possible to deal with such documents.

First, the handling of horizontally written and vertically written fonts in an electronic document format in which an electronic document can be described will be described.
Electronic documents are viewed electronically on a PC (Personal Computer).
When electronically browsing a document, text information described in the electronic document is selected on a PC, and processing such as copying and pasting (copying and pasting) is performed.
Select text information on the PC (for example, select text information by moving the text position to the right while left-clicking the mouse at the text position displayed on the display viewing the electronic document) If so, there is a viewer that highlights the selected text area and indicates which text information is selected. Note that a text area in which black and white is reversed by the selection operation is hereinafter also referred to as an inverted rectangular shape.
For example, as in the example shown in FIG. 2, there is an electronic document 200 in which “A” (character string 210), which is text information, is displayed. When the text information of “A” is selected on the PC, FIG. As shown in the selected character string 310 in the electronic document 200 shown in the example, the “A” part can be inverted to indicate to the user that “A” has been selected.
Alternatively, if copy and paste is performed on the PC in a state where the text information is selected as described above, it is possible to copy the text information “That” to another file. As in the example shown in FIG. 4, text information (character string 410) can be pasted on another application file (electronic document 400) such as a word processor.

  Next, in order to specify the character shape in such an electronic document, there are some which can include font information in the electronic document, such as PDF. That is, when the electronic document is printed or displayed on the screen, the font information (character shape information) is embedded in the electronic document in order to restore the character shape as intended by the user who creates the electronic document. By embedding font information in the electronic document in this way, recipients (printers, PCs, etc.) of electronic documents that do not have the same font information can restore the same character shape as the creator of the electronic document. become able to.

As fonts to be embedded in an electronic document, vertical writing fonts that are vertical writing fonts and horizontal writing fonts that are horizontal writing fonts exist.
When text information is selected in an electronic document, the operation differs between a vertical font and a horizontal font.
For example, when “A” (character string 210) in the example shown in FIG. 2 is described in a horizontal writing font, the viewer recognizes “A” as a single-line character string. Therefore, as in the example shown in FIG. 3, the inverted rectangular shape is a uniform shape as one rectangle.
However, when “A” (character string 210) in the example shown in FIG. 2 is described in vertical writing font, “A” is recognized as a vertical writing character string of 3 columns depending on the viewer. End up. As a result, the quality of the inverted rectangular shape can be degraded.

There are two types of quality deterioration of the inverted rectangular shape.
First, as in the example illustrated in FIG. 5, there may be a case where a blank space is generated between the inverted rectangular shapes (selected rectangles 510, 520, 530) of each character, that is, between “a”.
Secondly, as in the example shown in FIG. 6, the positions of the upper end and the lower end of the inverted rectangular shapes of “A”, “I”, and “U” may not be aligned.

Furthermore, when “A” in the example shown in FIG. 2 is described in a vertically written font, the quality of the copied and pasted text information also deteriorates.
When “Ah” is described in a horizontal writing font, the display result of the paste destination is as intended by the operator as in the example shown in FIG.
However, when “A” is written in vertical writing font, the viewer recognizes it as a vertical writing character string of 3 columns, and a line feed code is inserted, as shown in the example in FIG. The document 700 may be pasted as three lines of characters (character strings 710, 720, 730).

The above-described example is an example of a problem when horizontally written text information is described in a vertically written font.
Similarly, the same problem occurs when vertical text information is described in a horizontal font. That is, first, a blank is generated between the inverted rectangular shapes. Second, the positions of the left end and the right end of the inverted rectangular shape are not aligned. Third, as a result of recognizing one character string as a horizontal character string of a plurality of lines, a line feed code is inserted for each line.

In order not to cause such a problem, the character string of the horizontal writing text information may be described in the horizontal writing font, and the character string of the vertical writing text information may be described in the vertical writing font.
However, when embedding font information in an electronic document, simply embedding two fonts, a horizontal writing font and a vertical writing font, increases the file size.
As shown in the background art, there is a technique for extracting a common part between a horizontal writing font and a vertical writing font and holding the common part so as not to overlap, thereby reducing the file size.
However, when embedding font data in an electronic document, if the vertical writing font and the horizontal writing font are shared, information on whether each character is vertical writing or horizontal writing is lost. If the viewer has the function of recognizing whether the character is written horizontally or vertically, it may be solved. However, this solution depends on the specifications of the viewer, and is not solved when creating an electronic document. Moreover, the process of recognizing whether the viewer performs horizontal writing or vertical writing of characters is not necessarily consistent with the horizontal writing / vertical writing of the original electronic document.

  Hereinafter, examples of various preferred embodiments for realizing the present invention will be described with reference to the drawings. This embodiment is intended for an electronic document that includes font information therein, reproduces the horizontal writing and vertical writing of the character string of the electronic document, and reduces the file size.

An outline of the present embodiment will be described.
In the present embodiment, when a font having a common character shape (glyph) is present in vertical writing and horizontal writing, only one of the two fonts is embedded in the electronic document as a common font.
Furthermore, information that can refer to the common font as a vertical writing font, that is, a vertical writing font name (or vertical writing font number) is registered. The character for which the vertical writing font name (or vertical writing font number) is designated refers to the common font as a matter of fact.
Further, information that can refer to the common font as a horizontal writing font, that is, a horizontal writing font name (or horizontal writing font number) is registered. A character for which a horizontal font name (or a horizontal font number) is designated refers to a common font as a matter of fact.
When generating an electronic document, a font name (or font number) is designated for each character. That is, by specifying the font name (or font number), horizontal writing and vertical writing can be specified.

Furthermore, a drawing position is designated for each character.
In the case of sharing only those that can be shared among vertical and horizontal fonts, there are some fonts that have different drawing positions in vertical writing and horizontal writing. For example, punctuation marks such as “,” are drawn at the lower left in horizontal writing, but are drawn at the upper right in vertical writing. Therefore, punctuation marks cannot be shared. Proportional fonts cannot be shared because the font width (height) differs between characters in horizontal writing and vertical writing.
In the present embodiment, a drawing position is designated for each character. For this reason, the font of the character can be shared for the characters having the same character shape for horizontal writing and vertical writing. Thereby, the present embodiment can reduce the file size of the electronic document in which the font information is embedded.

The module generally refers to components such as software (computer program) and hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a computer program but also a module in a hardware configuration. Therefore, the present embodiment also serves as an explanation of a computer program, a system, and a method. However, for the sake of explanation, the words “store”, “store”, and equivalents thereof are used. However, when the embodiment is a computer program, these words are stored in a storage device or stored in memory. It is the control to be stored in the device. In addition, the modules correspond almost one-to-one with the functions. However, in mounting, one module may be composed of one program, or a plurality of modules may be composed of one program. A plurality of programs may be used. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. In the following, “connection” includes not only physical connection but also logical connection (data exchange, instruction, reference relationship between data, etc.).
In addition, the system or device is configured by connecting a plurality of computers, hardware, devices, and the like by communication means such as a network (including one-to-one correspondence communication connection), etc., and one computer, hardware, device.

The vertical writing information addition processing module 120 is connected to the common font processing module 110 and the character registration processing module 140, and adds information that can refer to the font received by the common font processing module 110 as a vertical writing font. Then, the assigned information is transferred to the character registration processing module 140.
The horizontal writing information addition processing module 130 is connected to the common font processing module 110 and the character registration processing module 140, and adds information that can refer to the font received by the common font processing module 110 as a horizontal writing font. Then, the assigned information is transferred to the character registration processing module 140.
That is, the vertical writing information addition processing module 120 assigns information that can refer to the common font as the vertical writing font in order to register the vertical writing font that refers to the same data with the common font as the parent font. For example, assume that the vertical font number is 1.
Similarly, the horizontal writing information addition processing module 130 assigns information that can refer to the common font as the horizontal writing font in order to register the horizontal writing font that refers to the same data with the common font as the parent font. For example, assume that the horizontal writing font number is 2. That is, when the font number is 1, the common font is referred to as a vertical writing font, and when the font number is 2, the common font is referred to as a horizontal writing font.

The character registration processing module 140 is connected to the common font processing module 110, the vertical writing information addition processing module 120, and the horizontal writing information addition processing module 130, and based on the font received by the common font processing module 110, the vertical writing processing is performed. Font information is generated together with information provided by the information addition processing module 120 or the horizontal writing information addition processing module 130.
In addition, the character registration processing module 140 is capable of referring to the generated font information and each character constituting the electronic document, the character position, the character size, the character color, and the font information of the character. Information for configuring the electronic document may be generated based on (hereinafter also referred to as font number). That is, the electronic document includes font information (including information that can refer to the font and the font as a horizontal font or information that can refer to the font as a vertical font), character position, character size, character color, Or it has the information which can refer to the font information of a character. In other words, the electronic document has at least information that can refer to font information, character positions, and character font information. More preferably, it has a character size and a character color. Furthermore, you may include the character code which is a character identifier which can identify the character uniquely. The character code uses a code system that can be used in common by a plurality of applications.

  Then, the viewer can refer to the font information of the character at the position of the character in the electronic document to be displayed (the character of the horizontal character string such as the number of the vertical font if it is a character of the vertical character string). If so, the corresponding font in the font information is acquired using the horizontally written font number, and the acquired font is drawn.

  In the first embodiment, the character position, character size, character color, and font number are designated for each character.

In other words, in this case, registration may be performed at the time of change. Further, other compression methods may be applied.

FIG. 8 is a conceptual module configuration diagram of a configuration example according to the second embodiment. This second embodiment shows an example of creating an electronic document by inputting image data.
It should be noted that the same parts as those in the first embodiment are shown to be the same as those in the first embodiment, and redundant description is omitted.

In the second embodiment, as shown in FIG. 8, a character code provision processing module 810, a representative character generation processing module 820, a common font processing module 830, a vertical writing information addition processing module 840, and a horizontal writing information addition processing module 850 are used. , A character string direction recognition processing module 860 and a character registration processing module 870.
Note that the image input to the second embodiment is a result obtained by reading a paper document with a scanner and analyzing the image. That is, in addition to the image itself, information on the image such as the position of the character image that is a pixel block (hereinafter also referred to as character position) and the size of the character image that is the pixel block (hereinafter also referred to as character size). Further, the image is a character image (hereinafter also referred to as a character image) that is a pixel block, a string of character images in which the character images are arranged vertically and horizontally (hereinafter also referred to as a character string), and the like.

A processing example of the second embodiment will be described with reference to FIG.
The representative character generation processing module 820 uses the character image 911, the character image 912, and the character image 913 in the input image 910 on which a plurality of characters “2” are described as target images. Each character image is cut out with the resolution of the character image 911. Then, the character size / character position 950 of each character image may be passed to the character registration processing module 870.
The representative character generation processing module 820 determines that the plurality of character images “2” are similar. Then, the representative character generation processing module 820 obtains the emphasis (intersection of the center of gravity line 911A, etc.) of the character image 911, the character image 912, and the character image 913, and moves the phase so that the emphasis is made coincident. 920 is generated and passed to the common font processing module 830.

The common font processing module 830 generates font data 930 that is outline information necessary for drawing an outline font, for example, from the high resolution character image 920 received from the representative character generation processing module 820.
The character code assignment processing module 810 assigns a character code 940 of a character image “2”, for example.
The character registration processing module 870 uses the font data received from the font data 930 and the vertical writing information addition processing module 840 as the vertical writing font or the font data received from the horizontal writing information addition processing module 850. Output using the font code, character code 940, character size / character position 950 that can be referred to as a horizontal writing font, and information indicating whether the character string received from the character string direction recognition processing module 860 is horizontal writing or vertical writing. Generate an electronic document to be used.

Next, each module will be described in detail.
The representative character generation processing module 820 is connected to the common font processing module 830, extracts similar character images for each character image in the image, and represents a character image representing them (hereinafter also referred to as a representative character image. As a specific example, a high-resolution character image is generated. The generated representative character image is transferred to the common font processing module 830.
As a method for extracting a character image, various conventionally proposed methods may be used. For example, techniques disclosed in JP 2000-57261 A, JP 2001-43314 A, JP 2004-78531 A, and the like may be used. Further, as a method for determining whether or not the character images are similar, for example, a technique disclosed in Japanese Patent Application Laid-Open No. 2007-174209 may be used.

An example of processing for generating a representative character image by the representative character generation processing module 820, that is, generating a high-resolution character image will be described with reference to FIG.
FIG. 10A illustrates a sampling grid (first sampling grid 1001, first sampling grid 1002, first sampling grid 1003, first resolution) at the resolution (first resolution) of the input image 910. The sampling grid 1004) and the centroid position (centroid 1001A, centroid 1002A, centroid 1003A, centroid 1004A) of the character image are shown.
First, as shown in FIG. 10B, the representative character generation processing module 820 moves the phases of the four sampling grids based on the center of gravity of the character image.

FIGS. 10C and 10D are diagrams illustrating an example of a technique for setting a sampling grid having a second resolution higher than the first resolution. The circled numbers (1, 2, 3, 4) described in FIG. 10C exemplify the value of the character image at the first resolution. Here, the character image is plotted so that the circled numbers are represented on the grid points of the sampling grid at the first resolution.
In FIG. 10D, the second sampling grid 1006 is a sampling grid for high-resolution images.
When the phases of the four sampling grids at the first resolution are moved, the representative character generation processing module 820 sets the sampling grid at the second resolution as shown in FIG. As shown in (D), the phase of the sampling grid at the second resolution is moved so that the centroids of the character images coincide.

FIG. 10E is a diagram for explaining an example of a technique for calculating the value of the character image at the second resolution. The circle numbers at the center of the second sampling grid 1006A, the second sampling grid 1006B, the second sampling grid 1006C, and the second sampling grid 1006D indicate the value of the character image at the second resolution. This is just an example. Here, the character image in the second resolution is shown such that the circled numbers at the center are represented on the grid points of the sampling grid in the second resolution.
Then, based on the phase of each character image at the first resolution, the representative character generation processing module 820 interpolates the pixel value of the character image at the second resolution from the pixel value of each character image. In this example, the representative character generation processing module 820 applies the nearest neighbor interpolation method to interpolate the pixel values of the character image at the second resolution. That is, the representative character generation processing module 820 performs sampling at the second resolution among the four values of the character image at the first resolution (circle numbers 1, 2, 3, and 4 in FIG. 10E). The value closest to the grid point is selected as the character image value at the second resolution. Specifically, in the second sampling grid 1006A, the value closest to the center is “1”, and “1” is adopted (the circled number is 1). The interpolation method is not limited to this method, and other methods (for example, linear interpolation method) may be applied.
The processing of the representative character generation processing module 820 is not limited to the processing described above, and linear interpolation, cubic convolution, or the like may be used.

The common font processing module 830 is connected to the character code addition processing module 810, the representative character generation processing module 820, the vertical writing information addition processing module 840, the horizontal writing information addition processing module 850, and the character registration processing module 870. For example, font data that is outline information of the representative character image received from the generation processing module 820 is generated, and a character code addition processing module 810, a character registration processing module 870, a vertical writing information addition processing module 840, and a horizontal writing information addition processing are generated. Pass to module 850.
The vertical writing information addition processing module 840 is connected to the common font processing module 830 and the character registration processing module 870, and is the same as the vertical writing information addition processing module 120 of the first embodiment.
The horizontal writing information addition processing module 850 is connected to the common font processing module 830 and the character registration processing module 870, and is the same as the horizontal writing information addition processing module 130 of the first embodiment.

The character code addition processing module 810 is connected to the common font processing module 830 and the character registration processing module 870, and assigns a character code to the input character image or the representative character image passed from the common font processing module 830. . Then, the character code is passed to the character registration processing module 870.
Further, the character code assigning processing module 810 may assign a code (font number) to the character shape so that the character shape registered as a font can have a one-to-one correspondence. In that case, a character code may be added to the character image in the input image corresponding to the input image. By assigning a character code, a character shape similar to the shape of the original character image can be reproduced from the common font.
The code (font number) to be assigned may be anything as long as it can correspond one-to-one with the character shape registered in the font. Alternatively, a character image may be recognized and a character code of a code system such as SJIS or Unicode may be given.

The character string direction recognition processing module 860 is connected to the character registration processing module 870, and recognizes the direction of the character string in the input image (whether it is horizontal writing or vertical writing). Then, the recognition result is passed to the character registration processing module 870.
Various methods used in general character recognition processing may be used for the character string direction recognition processing. For example, JP-A-5-35908, JP-A-5-35909, JP-A-5-35910, JP-A-5-62010, JP-A-5-73718, JP-A-5-89284, JP-A-5-298477, JP-A-5-314309, JP-A-6-243286, JP-A-8-194773, JP-A-9-200501, JP-A-2007-164719, etc. It is also possible to use a technique as described.

The character registration processing module 870 is connected to the character code addition processing module 810, the common font processing module 830, the vertical writing information addition processing module 840, the horizontal writing information addition processing module 850, and the character string direction recognition processing module 860.
Based on the font information generated by the common font processing module 830, the character registration processing module 870 generates font information together with the information provided by the vertical writing information addition processing module 840 or the horizontal writing information addition processing module 850.
Furthermore, the character registration processing module 870 generates information for configuring the electronic document based on the generated font information and information that can refer to the font information of the character identifier character assigned by the character code assignment processing module 810. You may make it produce | generate. The character registration processing module 870 further composes an electronic document based on the recognition result by the character string direction recognition processing module 860, information that can refer to the character position, character size, character color, and character font information. You may make it produce | generate the information for doing. In other words, the electronic document contains font information (including information that can refer to the font and the font as a horizontal font or information that can refer to the font as a vertical font), character position, character size, character color, character Information, a character code, or a direction of a character string. In other words, the electronic document has at least information that can refer to font information, character positions, and character font information. More preferably, it has a character size, a character color, and a character string direction. Furthermore, a character code may be included.

  In the second embodiment described above, for each character, the character position, character size, character color, font number, and character string direction are designated, but the character position, character size, When the same character color, font number, and character string direction continue (for example, in the case of a character position, the same X coordinate or Y coordinate, etc.) may not be specified for each character. In other words, in this case, registration may be performed at the time of change. Further, other compression methods may be applied.
