Description

  The present invention relates to an information processing apparatus having input means for receiving character input.

  In recent years, there has been an increasing demand for digitization (paperless) of documents and books. In particular, in the case of documents, there is a desire to edit on-the-spot text in an image captured as electronic data at the time of digitization.

  In order to edit such text in image data, a technique (OCR (Optical Character Reader)) for recognizing characters in image data is used.

  However, the conventional character recognition technology aims only at obtaining character information, and shape information such as character font (typeface data) is omitted in the recognition process. Therefore, when trying to correct characters in recognized image data, if the recognition processing side does not have the same font as the character font on the scanned image data that is the acquisition source, a different font is used. Will be corrected. As a result, there is a problem that a sense of incongruity occurs in the surrounding characters because the fonts are different. In this regard, for example, Japanese Patent Application Laid-Open No. 2009-110246 discloses a method of reproducing a font by converting an input character string using a conversion dictionary held in the device. Without it, it cannot be reproduced. In addition, when all of the input character string fonts are adapted, there is a problem that the file capacity of the conversion dictionary increases enormously.

  Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts and components are denoted by the same reference numerals. Their names and functions are also the same. The following description will be made using a multifunction peripheral (MFP (Multi Function Peripheral)) which is an example of an information processing apparatus and a kind of image forming apparatus.

FIG. 1 is a schematic diagram illustrating an image forming apparatus according to an embodiment of the present invention.
Referring to FIG. 1, image forming apparatus 1 according to the embodiment of the present invention includes control unit 100, HDD 110, scanner 120, operation panel 130, printer 140, printer controller 150, and network I / F 160. And an internal bus 170. The network I / F 160 is connected to an external network (not shown).

  The CPU 101 includes a ROM 102 that stores a control program, a working S-RAM (Static Random Access Memory) 103, and a battery-backed NV-RAM (nonvolatile memory) 104 that stores various settings relating to image formation. A clock IC 105 capable of timing is connected via an internal bus 170 to constitute the control unit 100.

  The control unit 100 transmits and receives various types of information to and from a scanner 120 that reads a document image, an operation panel 130 that includes various input keys and a display unit, and an external device connected via a network. Network I / F 160, a printer controller 150 for generating a copy image from print data received by the network I / F 160, and a printer 140 for forming a copy image on paper are connected via an internal bus 170. Yes.

  Further, a fixed storage device (HDD) 110 is connected to the control unit 100 via an internal bus 170. The fixed storage device 110 is, for example, a hard disk device. In this example, a fixed storage device (HDD) 110 stores saved data according to a BOX job.

  In addition, a program for executing character recognition and input character correction described below is stored in the HDD 110, for example, and various functions are executed by the CPU 101 reading and executing the program. Note that the program may be in another storage area in the control unit 100, may hold the program in advance, or may be downloaded and held via a network. good. As an input means for inputting characters, the operation panel 130 can be used, and information on the characters, specifically, conversion dictionaries, fonts (font data), and the like are stored in the HDD 110 or the like. It shall be.

  FIG. 2 is a conceptual diagram illustrating editing of text on image data in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 2, here, image data obtained by scanning a document is shown. A case of editing a part of the text in the image data will be described.

  Specifically, in the character region “I want to change document 3” on the scanned image data, the character “change” is changed to the character “correction”.

  First, on the scanned image data, a position for changing a character is selected. In this example, changing the character includes not only replacing the character with a different character but also deleting the character.

  Then, the surrounding area is set according to the selected position, and character feature information is acquired from the characters included in the surrounding area. Specifically, the feature information related to the line segment forming the character, the feature information related to the shape of the start point and the end point of the line segment, and the like are acquired.

  On the other hand, after selecting the position to change the character, the character to be changed is input. In this example, as an example, the characters “change” are deleted by the input means and the characters “correct” are input. In this example, as an input means, it is assumed that the character can be input using a soft keyboard as an interface using the operation panel 130. Note that the program such as the soft keyboard is stored in the HDD 110 in advance.

  Then, the input “correction” character is corrected based on the character feature information included in the peripheral area. Then, the corrected character is reflected on the selected position on the image data.

  By this processing, even if the font does not have the same font as the character on the image data, the character feature information is acquired from the characters included in the peripheral area on the image data, and the acquired character feature information is obtained. Since it is possible to correct the character based on this, it is possible to edit with less discomfort when editing a part of the text on the image data. Furthermore, it is not necessary to store various fonts related to characters on the image data in the HDD, and if there is at least one font, editing can be performed using the font, so that restrictions such as the capacity of the HDD are reduced. Is also possible.

Hereinafter, it is a flowchart explaining the change process of the character according to embodiment of this invention.
FIG. 3 is a flowchart of character change processing in the image forming apparatus according to the embodiment of the present invention. The job process is a process mainly executed by the CPU 101 of the control unit 100 of the image forming apparatus 1 and cooperates with other units as necessary.

  First, image data is acquired (step S2). Specifically, it is possible to acquire image data by reading a document with the scanner 120. Or you may make it acquire via a network from the outside. Note that the image data in this example is image data including characters.

  Next, character position information is acquired (step S4). Specifically, on the image data, each region of the elements constituting the character included in the image is specified, and position information for each character is acquired. As a result, correction can be performed in character units in accordance with instructions from the input means. For example, it is possible to specify one character area and acquire position information by using a known OCR.

  Next, it is determined whether or not there is a character position selection by the input means (step S6). Specifically, for example, a character position selection may be instructed by using a pointing means such as a mouse as an input means, or position selection may be instructed by a touch panel or the like.

  In step S6, when there is no character position selection by the input means (NO in step S6), this state is maintained.

  On the other hand, if there is character position selection by the input means in step S6 (YES in step S6), the process proceeds to the next step S8.

  Then, it is determined whether there is an input character (step S8). In this example, as an example, it is assumed that the character can be input using a soft keyboard as an interface using the operation panel 130. It is determined whether there is an input character using the soft keyboard.

  If it is determined in step S8 that there is an input character (YES in step S8), processing for correcting the character is executed (step S9). Details of the character correction processing will be described later.

Then, the character change is reflected (step S10).
On the other hand, if it is determined in step S8 that there is no input character (NO in step S8), step S9 is skipped and the process proceeds to step S10 to reflect the change of character (step S10). For example, as a case where it is determined that there is no input character, as a case where a change in character is reflected, for example, only deletion of a character can be cited.

  FIG. 4 is a flowchart of processing for correcting characters in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 4, first, a peripheral area is set (step S14). Specifically, the position information on the image data where the position of the character is selected is acquired, and the peripheral area is specified based on the position information. For example, it is possible to provide a frame to be set as a peripheral area in advance as an example, and set the peripheral area with reference to the position information. Note that the reason for setting the peripheral region is that the region is limited so as not to be overloaded because the extraction of characters and the calculation of feature amounts become enormous when all regions on the image data are set as the peripheral region. Is.

  Next, peripheral characters included in the peripheral region are extracted (step S16). Specifically, peripheral characters included in a frame set based on the position information are extracted. Note that the same character or the like is duplicated, so that the amount of calculation can be reduced by ignoring it. Further, in this example, kanji characters are extracted as characters to be extracted in order to acquire character characteristics. Whether or not it is a Chinese character can be determined by using a known OCR as an example.

  Next, the characteristics of the surrounding characters are acquired (step S18). Information indicating character characteristics is acquired from the extracted characters (kanji).

  Next, a process for correcting the input character is executed (step S19). The input character is corrected based on the acquired character characteristics.

Then, the process ends (return).
FIG. 5 is a flowchart illustrating in detail step S19 in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 5, the process of step S <b> 19 includes a process of correcting the input character according to the characteristics of surrounding characters (step S <b> 20).

  FIG. 6 is a diagram for explaining a specific example in a case where an input character is corrected according to the characteristics of surrounding characters.

  Referring to FIG. 6, here, as an example, a diagram in which a character “Ei” is extracted as a peripheral character on the image data is shown.

  And the case where the skeleton information of the character “Ei” is acquired and the width of the line orthogonal to the line segment acquired as the skeleton information is acquired for each line segment in each direction is shown. Not only the vertical and horizontal directions but also line segments such as diagonal directions are acquired.

  On the other hand, as an example, for example, the input character is “sentence”, and the “sentence” character that is included in the format data is corrected. Specifically, the character is corrected based on the characteristic information (width of the line segment) regarding the line segment of the surrounding character “Ei”.

  FIG. 7 is a diagram illustrating a case where the character width of the input character according to the embodiment of the present invention is corrected.

  With reference to FIG. 7, here, a case where the input character is “sentence” and the character of “sentence” is corrected as format data will be described. First, the skeleton information of the character of “sentence” is acquired, and the character width is corrected in the direction perpendicular to the line segment acquired as the skeleton information. Specifically, the character width is corrected based on the value (characteristic information) regarding the width of the line segment in each direction from the character “periphery” as the peripheral character on the image data.

  FIG. 8 is a diagram illustrating another case of correcting the character width of the input character according to the embodiment of the present invention.

  With reference to FIG. 8, here, a case where the input character is “sentence” and the character “sentence” is corrected as format data will be described.

  The character of the “sentence” of the format data is compared with the character of “permanent” on the image data, and the character width of the “sentence” of the format data is corrected according to the character of “permanent” on the image data.

  Specifically, the line width of the “sentence” line in the format data is compared with the line width of the “permanent” line in the same direction, and the width of the “sentence” line in the format data is set to the “eternal” line. Correct for minutes.

  With this correction, even if the font does not have the same font as the character on the image data, the character feature information is acquired from the character included in the peripheral area on the image data, and the acquired character feature information It is possible to correct the character based on it. Here, by aligning the line width according to each direction, the character characteristics of the surrounding area are reflected in the input characters, so editing with a little discomfort is possible when editing part of the text on the image data It becomes.

Next, another point that reflects character characteristics will be described.
FIG. 9 is a diagram for explaining another specific example in the case where the input character is corrected in accordance with the characteristics of surrounding characters.

  Referring to FIG. 9, here, as an example, a diagram in the case where a character “permanent” is extracted as a peripheral character on the image data is shown.

  And the case where the skeleton information of the character "Ei" is acquired and the shape of the end point part is acquired for each line segment acquired as the skeleton information is shown. Not only the vertical and horizontal directions but also line segments such as diagonal directions are acquired.

  On the other hand, as an example, for example, the input character is “sentence”, and the “sentence” character that is included in the format data is corrected. Specifically, the character is corrected based on the feature information (end point shape) regarding the line segment of the surrounding character “Ei”.

  The end points include a start point and an end point. The shape of the start point and end point of the line segment is acquired for each line segment in each direction, and the end points of the line segments in each direction of the characters of the format data are matched with the acquired shape.

  FIG. 10 is a character feature table showing character feature information acquired from characters extracted as peripheral characters on the image data according to the embodiment of the present invention.

  FIGS. 10A and 10B show a case where the line segments are separated from each other and a case where the line segments are not independent and connected to each other.

  10A and 10B, the width of the line segment in each direction, the shape of the start point and the shape of the end point of the line segment are respectively acquired and registered. Here, as an example, for the line segments in the directions of “from top to bottom”, “from left to right”, “from top left to bottom right”, and “from top right to bottom left” The width of the minute and the shape of the start point and end point are registered.

  The line segment width (pt) may be an average value from the start point to the end point, or may be defined by a range. As the shape, a matching shape is registered by matching with a predetermined shape. In addition, the said shape does not need to correspond completely and a similar shape may be sufficient. In this example, for example, the case where the shape A and the shape B are registered is shown as an example.

  In this example, the table is divided into a case where the line segments are independent and a case where the line segments are connected, and the case where the corresponding line segments are corrected is described. It is good also as one table, without dividing whether it is independent or connected. It is also possible to use a table with only the width of the line segment, or a table with only the shape of the end points. In this example, the case of four directions is described as the direction of the line segment, but more accurate correction is possible by acquiring and reflecting the characteristic information of the line segments in a plurality of directions. .

  By this processing, even if the font does not have the same font as the character on the image data, the character feature information is acquired from the characters included in the peripheral area on the image data, and the acquired character feature information is obtained. It is possible to correct characters based on this, and editing with less discomfort is possible when editing a part of a sentence on image data. Furthermore, it is not necessary to store various fonts related to characters on the image data in the HDD, and if there is at least one font, editing can be performed using the font, so that restrictions such as the capacity of the HDD are reduced. Is also possible.

  In addition, a character to be extracted as a peripheral character may be determined in advance to reduce the load of acquiring characteristic information of the peripheral character.

(Modification 1)
In the above description, the case where the input character is corrected to the character of the surrounding character has been described. However, the case where the font of the surrounding character is the same as the format data may be considered. Processing in this case will be described.

  FIG. 11 is a flowchart illustrating in detail Modification 1 of step S19 in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 11, it is determined whether or not the characteristics of surrounding characters are the same as the format data (step S22).

  If it is determined in step S22 that the characteristics of the surrounding characters are the same as the format data (YES in step S22), the input characters are not corrected (step S24).

Then, the process ends (return).
On the other hand, if it is determined in step S22 that the characteristics of the surrounding characters are not the same as the format data (NO in step S22), the input characters are corrected according to the characteristics of the surrounding characters (step S26). Since this process is the same as that described above, detailed description thereof will not be repeated.

Then, the process ends (return).
With this processing, if the font of surrounding characters is the same as the format data, it is not necessary to make corrections, and the input characters are reflected without correction.

The correction process can be executed without applying unnecessary load by the process.
Note that the determination as to whether or not the characteristics of the surrounding characters are the same as the format data is made by, for example, having a table as shown in FIG. 10 for the format data in advance and obtaining the feature information obtained from the surrounding characters. It is possible to determine whether or not they are the same by comparing with. Or you may make it judge whether the similarity in the shape of the character extracted from the periphery and the character to which a format data respond | corresponds is the same.

  In the above-described step S22, the case where it is determined whether or not the characteristics of the surrounding characters are the same as the format data has been described. However, it is not limited to the same, and it may be determined whether or not they are similar. good. If they are similar to a certain extent, editing with less sense of incongruity is possible, and in this case, it is possible to reduce the burden of correction documents by not correcting them.

(Modification 2)
In the above description, the case where the input character is corrected to the feature of the surrounding character has been described. However, a method capable of editing with less discomfort will be described.

  FIG. 12 is a flowchart illustrating in detail a modification 2 of step S19 in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 12, it is determined whether or not the characteristics of surrounding characters are the same as the format data (step S22).

  If it is determined in step S22 that the characteristics of the surrounding characters are the same as the format data (YES in step S22), the input characters are not corrected (step S24).

Then, the process ends (return).
On the other hand, if it is determined in step S22 that the characteristics of surrounding characters are not the same as the format data (NO in step S22), character recognition processing is executed (step S34). As the character recognition process, for example, a known OCR is used as an example.

  Next, as a result of the character recognition process, it is determined whether or not there is a character identical to the input character in the surrounding characters (step S36).

  If it is determined in step S36 that there is the same character (YES in step S36), the same character is copied (step S38).

  Next, it is determined whether there are other characters (step S40). When there are other characters, it is determined whether or not the same character exists for the character.

  If it is determined in step S40 that there are other characters (YES in step S40), the process returns to step S36.

  On the other hand, if it is determined in step S40 that there are no other characters, the process ends (return).

  In the process of reflecting the character change, the copied character is reflected as the input character.

  On the other hand, if it is determined in step S36 that there is no identical character (NO in step S36), the input character is corrected according to the characteristics of surrounding characters (step S26). Since this process is the same as that described above, detailed description thereof will not be repeated.

Then, the process ends (return).
When the same character as the input character is included in the peripheral area by the processing, editing with less discomfort is possible by copying the character included in the peripheral area and using it as the input character. Whether or not there is the same character as the input character can be searched by expanding the peripheral area, for example, the entire image data.

  When the character font is the same as the format data, the input character is reflected without correction because it is not necessary to correct it.

(Modification 3)
In the above description, the case where the input character is corrected to the feature of the surrounding character has been described. However, a method capable of editing with less discomfort will be described.

  FIG. 13 is a flowchart illustrating in detail Modification 3 of step S19 in the image forming apparatus according to the embodiment of the present invention.

  Referring to FIG. 13, it is determined whether or not the characteristics of surrounding characters are the same as the format data (step S22).

  If it is determined in step S22 that the characteristics of the surrounding characters are the same as the format data (YES in step S22), the input characters are not corrected (step S24).

Then, the process ends (return).
On the other hand, if it is determined in step S22 that the characteristics of surrounding characters are not the same as the format data (NO in step S22), character recognition processing is executed (step S34). As the character recognition process, for example, a known OCR is used as an example.

  Next, as a result of the character recognition process, it is determined whether a part of the surrounding characters and the shape of the part of the input character are the same (step S50). Specifically, for example, as a case where some shapes are the same, a case where the radicals are the same can be mentioned. Whether the radicals are the same may be determined by storing dictionary information grouped in advance for each radical and determining whether the radicals are the same based on the dictionary information.

  If it is determined in step S50 that a part of the surrounding characters and the shape of the part of the input character are the same (YES in step S50), a part of the part is copied (step S52).

  Then, the remaining part of the input character is corrected according to the characteristics of the surrounding characters (step S54).

Next, it is determined whether or not there are other characters (step S56).
If it is determined in step S56 that there are other characters (YES in step S56), the process returns to step S50.

  On the other hand, if it is determined in step S56 that there are no other characters, the process ends (return).

  Then, in the process of reflecting the change of the character, a part of the copied character and the corrected remaining part are reflected as the input character.

  On the other hand, if it is determined in step S50 that some of the surrounding characters are not the same as the shape of some of the input characters (NO in step S50), the input characters are corrected according to the characteristics of the surrounding characters. (Step S26). Since this process is the same as that described above, detailed description thereof will not be repeated.

Then, the process ends (return).
FIG. 14 is a diagram for explaining a specific example in a case where the shape of a part of an input character is corrected according to the characteristics of surrounding characters.

  Referring to FIG. 14, here, as an example, a diagram in the case where a character “jo” is extracted as a peripheral character on the image data is shown.

  On the other hand, for example, a case where the input character is “惰” will be described. The radicals for the Chinese characters "jo" and "惰" are the same. That is, a part of the surrounding characters and the shape of a part of the input characters are the same.

  Therefore, the radical part of the Chinese character “jo” is divided and copied and replaced with the radical “惰” of the input character. Further, the remaining portion of the input character “惰” is corrected based on the feature information of the surrounding characters.

  With this correction, even if the font does not have the same font as the characters on the image data, the shape of some of the characters included in the peripheral area on the image data and the shape of some of the input characters are the same If it is, copy the same shape part and reflect it. As a result, since some of the character features of the peripheral area are reflected in some of the input characters, editing with less discomfort is possible when editing a part of the text on the image data.

  If all the shapes are the same but not a part of the characters, the whole may be copied and reflected as described with reference to FIG.

  In the above description, an example in which the input characters are mainly kanji has been described. However, the present invention is not limited to kanji and can be similarly applied to hiragana and the like. In addition, it is not limited to Japanese, and other format data such as alphabets can be similarly reflected.

  Note that the MFP that is the image forming apparatus has been described as an example of the information processing apparatus according to the present invention. However, the present invention is not particularly limited thereto, and may be a printer apparatus, a facsimile apparatus, or the like.

  It is also possible to provide a program that causes a computer to function and execute control as described in the above flow. Such a program is stored in a computer-readable recording medium such as a flexible disk attached to the computer, a CD-ROM (Compact Disk-Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card. And can be provided as a program product. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. As such storage media, semiconductor memories such as flash memory, mask ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), IC (Integrated Circuit) card, CD-ROM (Compact Disc-Read Only Memory) and optical disc storage media such as DVD-ROM (Digital Versatile Disk-Read Only Memory), magneto-optical disc storage media such as MO (Magnetic Optical Disc) and MD (Mini Disc), FD ( Magnetic storage media such as Flexible Disk), magnetic tape, and cassette tape can be used.

  The program according to the present invention is a program module that is provided as a part of a computer operating system (OS) and calls necessary modules in a predetermined arrangement at a predetermined timing to execute processing. Also good. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS.
