Description

The present invention relates to an image processing device.

Conventionally, character recognition is performed by OCR (Optical Character Recognition) processing of scanned original images and document images in image forming devices such as MFPs (Multifunction Peripherals) that have an image reading function. There are known techniques for

As an invention using such character recognition technology, there has been disclosed an invention of a character editing processing device capable of automatically enlarging characters smaller than a specified size in a document according to a certain rule (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2001-202362

By the way, documents such as academic papers and reports usually contain a mixture of small characters and figures/tables.

However, when the characters recognized by character recognition technology are enlarged, only the characters become larger than the figures and tables, and the relative positional relationship and ratio may change significantly, resulting in the collapse of the overall layout of the figures and tables. As a result, there is a problem that the characters are more difficult to see than before enlargement.

On the other hand, there is also a method of enlarging the entire figure/table including text at the same ratio.・There was also the problem that the layout of the sentences around the table collapsed, making it more difficult to see the characters than before enlargement.

The present invention has been made in consideration of the circumstances described above, and its object is to provide an image display method that can enlarge and display even a document in which characters and figures/tables are mixed so that the layout is easier to see than before. A processing device is provided.

(1) The present invention comprises an image processing section that analyzes image data including characters and graphics and performs predetermined image processing, and a control section that controls the image processing section, wherein the image processing section When performing enlargement editing processing for enlarging the size of characters in data to a predetermined size or larger, the control unit causes the image processing unit to analyze the image data and extract character information and graphic information separately. and, when a character smaller than the specified size is included in the graphic, the character is enlarged within a range that fits within the graphic, and then rearranged within the graphic. is.

In the present invention, "when a figure contains characters smaller than the specified size" is not limited to cases where characters are included inside the figure, such as each cell of a table. Elements such as headings, axis labels/titles, captions, etc., which are generally considered to be part of the graphics, shall contain characters inside the graphics.
“Enlarging the character within the range of the figure” means enlarging the character so as to fit within the figure so as to have a predetermined margin size (for example, 1 mm) or more.

According to the present invention, it is possible to realize an image processing apparatus that enlarges and displays even a document in which characters and figures/tables are mixed so that the layout is easier to see than before.

In conventional enlarging and editing processing of characters in a figure, the entire figure including characters is uniformly enlarged at the same ratio. Since the characters are enlarged and rearranged so that they fit, it is possible to enlarge the characters regardless of the positional relationship between the figure and the characters before enlargement. .

Furthermore, preferred embodiments of the present invention will be described.

(2) The image processing apparatus of the present invention further includes an operation unit for receiving a command from a user, and the operation unit receives an enlargement editing command for enlarging the size of characters in the image data to a predetermined specified size or more. In this case, the control unit causes the image processing unit to analyze the image data and extract character information and graphic information separately. After enlarging the character within the range that it fits, the character may be rearranged within the figure.

In this way, even when an enlargement editing command is received from the user, the characters and figures are enlarged and rearranged so that the characters are larger than the specified size within the range of the figures. It is possible to realize an image processing apparatus that enlarges and displays a mixed document so that the layout is easier to see than before.

(3) In the image processing apparatus of the present invention, if the character cannot be enlarged beyond the specified size even if the character is enlarged within the range of the figure, the control section enlarges the character within the figure. The graphics and characters may be enlarged and rearranged by the image processing unit so that the characters are larger than the designated size.

In this way, the characters and graphics are enlarged and rearranged so that the characters are larger than the specified size within the range of the figure. It is possible to realize an image processing apparatus that enlarges and displays the layout so that the layout is easier to see than before, without being bound by the positional relationship between the characters.

(4) In the image processing apparatus of the present invention, if the character cannot be enlarged beyond the designated size even if the figure is enlarged, the controller determines whether the image data including the character and the figure has a multi-column structure. If there is a multi-column structure, the image processing unit cancels the multi-column structure and adjusts the character and the graphic so that the character is larger than the designated size within the range of the graphic. may be enlarged and rearranged.

In this way, even if the figure is enlarged, even if the characters in the figure cannot be enlarged beyond the specified size, if the figure has a multi-column structure, the multi-column structure will be canceled and the character will fit within the figure. In order to enlarge and rearrange the characters and figures so that the characters are larger than the specified size within the range, we developed an image processing device that enlarges and displays the layout of documents that contain a mixture of characters and figures/tables. realizable.

(5) In the image processing apparatus of the present invention, when causing the image processing section to enlarge and rearrange the characters and graphics, the control section extracts a keyword indicating the graphics from characters outside the graphics, and extracts a keyword indicating the graphics from the keywords. The graphics may be rearranged within a predetermined range.

"Extract a keyword indicating the figure" is a keyword indicating the figure, such as "shown in Figure XX" or "see Figure XX".
"Within a predetermined range from the keyword" means, for example, within the same page as the keyword, or in the upper half of the page when the keyword is on the top of the page, and on the bottom of the page when the keyword is on the bottom of the page. such as the bottom half of the page.

In this manner, when enlarging and rearranging characters and figures, a keyword indicating the figure is extracted from characters outside the figure, and the figure is rearranged within a predetermined range from the keyword. It is possible to realize an image processing apparatus that enlarges and displays even a document in which figures and tables are mixed so that the layout is easier to see than before.

(6) In the image processing apparatus of the present invention, if the character cannot be enlarged beyond the specified size even if the figure is enlarged, the control unit performs the image processing on a new page in which the figure is enlarged to the entire page. It may be output to the department.

In this manner, when the characters in the figure cannot be enlarged beyond the specified size even if the figure is enlarged, a new page with the figure enlarged to the entire page is output. Even so, it is possible to realize an image processing apparatus that enlarges and displays the layout so that it is easier to see than before.

<Flow of Image Editing Process of Digital MFP 1 According to Embodiment 1 of the Present Invention>
Next, the flow of image editing processing of the digital multifunction peripheral 1 according to the first embodiment of the present invention will be described with reference to FIGS. 3 to 7. FIG.

<Problems with conventional image editing processing>
First, based on FIG. 3, the problems of conventional image editing processing will be described.

FIG. 3 is an explanatory diagram showing an example of image editing processing of a conventional digital multi-function peripheral.
FIGS. 3A and 3B are explanatory diagrams showing an example of editing of image data before image editing and after image editing, respectively.

In FIG. 3A, it is assumed that the character information is enlarged in the image data including the character information in the figure (rectangular frame).

In this case, in conventional image enlargement processing, as shown in FIG. 3(B), character information is normally enlarged for each figure at a fixed ratio.

However, since some character information in the graphic is too small to be seen by the user, it is often sufficient if the character information can be enlarged to a size that is easy for the user to see.
Therefore, there is no need to enlarge even character information and graphics that are already large and easy to see.

In addition, if the figure is enlarged, the arrangement of the character information C3 (shaded portion in FIG. 3) around the figure also changes greatly.

For example, as shown in FIG. 3(A), "According to the character information in the left frame..." is displayed on the right side of the figure, and at the bottom of the page, "Here, the character information in the upper frame is Please refer to it again." is displayed.

Here, as shown in FIG. 3B, if the character information is enlarged for each figure, the arrangement of the character information around the figure changes greatly.
As a result, "According to the text information in the left frame" is displayed at the bottom of the figure, and "Here, please refer to the text information in the upper frame again." at the bottom of the page. will be displayed on the next page, so there is a risk that it will be more difficult to grasp the information than before the enlargement.

FIG. 4 is a flow chart showing an example of image editing processing of the digital multi-function peripheral 1 according to Embodiment 1 of the present invention.
FIG. 5 is an explanatory diagram showing an example of image editing processing of the digital multifunction peripheral 1 of FIG.
FIGS. 5A and 5B are explanatory diagrams showing an example of image data editing before and after image editing, respectively.

In FIG. 4, it is assumed that enlargement editing processing for enlarging a small and hard-to-see character such as the character information C2 in FIG. 5A is started.

Note that the control unit 10 may cause the image processing unit to execute enlargement editing processing even when the operation unit 172 receives an enlargement editing command from the user.

In step S1 of FIG. 4, the control unit 10 causes the image processing unit 14 to perform image analysis of the image data acquired by the image data acquisition unit 11, and separately extracts character and graphic information from the image data (step S1 ).

In the example of FIG. 5A, the rectangular frame-shaped graphic information D1, two pieces of character information C1 and C2 in the graphic information D1, and the character information C3 indicated by hatching are extracted.

Next, in step S2 of FIG. 4, the control unit 10 determines whether character information is included in the extracted graphic information (step S2).

Here, "text information is included in graphic information" is not limited to the case where characters are included in the graphic such as each cell of a table. Elements such as labels, titles, captions, etc., which are generally considered to be part of the graphics, shall include characters inside the graphics.

Further, in the case of mathematical formulas, even if only characters are used, characters may be included inside the figure.

If character information is not included in the extracted graphic information (determination in step S2 is No), in step S3, if there is character information smaller than the predetermined size, the control unit 10 determines that the character information is reduced to the predetermined size. The image processing unit 14 is caused to enlarge the image so as to become the above (step S3).

On the other hand, if character information is included in the extracted graphic information (if the determination in step S2 is Yes), in step S4, the control unit 10 analyzes the character size and the size of the graphic in the graphic (step S4).

In the following step S5, the control unit 10 determines whether or not the characters can be enlarged and rearranged to a predetermined size or more within the range of the figure, based on the analysis result of the size of the characters in the figure and the size of the figure. (step S5).

Here, "enlarging and rearranging the characters to a predetermined size or more within the range that fits within the figure" means having a predetermined margin size (for example, 1 mm) or more, so that the characters fit within the figure. Enlarging letters.

If the characters can be enlarged and rearranged to a predetermined size or more within the range that fits within the figure (if the determination in step S5 is Yes), in step S6, the control unit 10 enlarges the characters to a predetermined size or more within the range that fits within the figure. Then, the characters are enlarged and rearranged in the image processing unit 14 (step S6).

In the example of FIG. 5B, only the character information C2, which is small and difficult to see in FIG. 5A, is enlarged and rearranged within the graphic information D1.

On the other hand, in step S5 of FIG. 4, if it is not possible to enlarge and rearrange the characters to a predetermined size or more within the range within the graphic (if the determination in step S5 is No), in step S7, the control unit 10 After enlarging the character, the character is enlarged and rearranged by the image processing unit 14 to a predetermined size or larger within the range of the figure (step S7).

In this case, the control unit 10 causes the image processing unit 14 to enlarge the graphic so that the characters in the graphic are larger than a predetermined size.

FIG. 6 is an explanatory diagram showing another example of image editing processing of a conventional digital multi-function peripheral.
FIGS. 6A and 6B are explanatory diagrams showing an example of image data editing before and after image editing, respectively.

In FIG. 6A, it is assumed that, in image data including text information in a table, the text information is enlarged.

In this case, in conventional image enlargement processing, as shown in FIG. 6(B), it was normal to uniformly enlarge the entire table including character information.

However, if the frame of the table is enlarged together with the character information, the arrangement of the character information around the table (the shaded portion in FIG. 6) will also change significantly, so there is a risk that the information will be more difficult to grasp than before enlargement. .

FIG. 7 is an explanatory diagram showing another example of image editing processing of the digital multi-function peripheral 1 of FIG.
FIGS. 7A and 7B are explanatory diagrams showing an example of image data editing before and after image editing, respectively.

In the example of FIG. 7A, graphic information D1 of the entire table, 18 character information C1 to C18 in the table, and character information C19 indicated by hatching are extracted.

In the example of FIG. 7B, the character information C1 to C18, which are small and difficult to see in FIG. 7A, are enlarged and rearranged within the graphic information D1.

Here, the difference from conventional table enlargement is that in the example shown in FIG. The graphic information D1 and the character information C1 to C18 are enlarged and rearranged within a range that fits.

Therefore, unlike the conventional process of simply enlarging the entire table, only the character information C1 to C18 can be enlarged to a size that is easy to see without greatly disturbing the arrangement of the character information C19 (shaded portion in FIG. 7) around the table. and user-friendliness.

In fact, although the font sizes of the character information in the tables of FIGS. 6B and 7B are the same, the table of FIG. 7B fits more compactly than the table of FIG. 6B. I know there is.

(Modification)
As a modification of the first embodiment, when the graphic information to be enlarged and rearranged includes a monochrome graph, the graph may be enlarged and rearranged as a color graph based on the shades of the monochrome graph.

On the other hand, if the graphic information to be enlarged and rearranged includes a color graph, it will be enlarged and rearranged as a monochrome graph by changing the shape of the graph line, adding markers, etc., based on the colors of the relevant color graph. can be

In this way, character information and graphic information are separately extracted, and then the characters and graphics are enlarged and rearranged so that they fit within the graphic. Since figures can be enlarged, it is possible to realize the digital multifunction peripheral 1 that enlarges and displays even a document in which characters and figures/tables are mixed so that the layout is easier to see than before.

<Image Editing Process of Digital MFP 1 According to Embodiment 2 of the Present Invention>
Next, image editing processing of the digital multi-function peripheral 1 according to Embodiment 2 of the present invention will be described with reference to FIGS. 8 to 10. FIG.

A digital multi-function peripheral 1 according to Embodiment 2 of the present invention has the same configuration as the digital multi-function peripheral 1 of FIG. 2 (Embodiment 1), so description thereof will be omitted.

FIG. 8 is a flow chart showing an example of image editing processing of the digital multi-function peripheral 1 according to Embodiment 2 of the present invention.
Note that the processing of steps S11 to S16 in FIG. 8 corresponds to the processing of steps S1 to S6 in FIG. 4 (embodiment 1), respectively, so description thereof will be omitted.

Here, processing of steps S17 to S20 in FIG. 8, which are not described in the first embodiment, will be described.

In step S15 of FIG. 8, if it is not possible to enlarge and rearrange the characters to a predetermined size or more within the range within the graphic (if the determination in step S15 is No), in step S17, the control unit 10 enlarges the graphic. However, it is determined whether or not it is smaller than a predetermined size (step S17).

If the enlarged figure becomes larger than the predetermined size (if the determination in step S17 is No), in step S18, after enlarging the figure, the control unit 10 performs image processing on the characters to a size larger than the specified size within the range that fits within the figure. The part 14 is caused to enlarge and rearrange (step S18).
After that, the control unit 10 performs the process of step S20, which will be described later.

On the other hand, if the enlarged figure is still smaller than the predetermined size (if the determination in step S17 is Yes), in step S19, the control unit 10 determines if the character information has a multi-column structure and the multi-column structure can be canceled. After enlarging the figure, the characters are enlarged and rearranged by the image processing unit 14 to a predetermined size or larger within the range of the figure (step S19).

Next, in step S20, the control unit 10 extracts a keyword indicating a figure from the character information (for example, "shown in figure XX", "see figure XX", etc.), and finds an enlarged figure related to the keyword. Rearrange (step S20).

FIG. 9 is an explanatory diagram showing an example of image editing processing of the digital multifunction peripheral 1 according to Embodiment 2 of the present invention. FIGS. 9A and 9B are explanatory diagrams showing an example of image data editing before and after image editing, respectively.

The example of FIG. 9A has a two-column structure of character information C19 and C20.
If the multi-column structure can be canceled by a predetermined setting, the multi-column structure is canceled as shown in the example of FIG. to relocate.

Note that the control unit 10 determines whether or not the sentence has a multi-column structure, and what kind of multi-column structure, based on the position of the beginning of the sentence, the margins in the sentence, and the positions of the end characters of the sentence such as punctuation marks and periods. It shall be determined whether the

In the example of FIG. 9B, since the keyword "according to Table 1" is included in the character information C20 on the second page, the enlarged graphic information D1 of Table 1 is rearranged near the character information C20. be.

FIG. 10 is an explanatory diagram showing another example of image data after image editing by the digital multifunction peripheral 1 according to the second embodiment of the present invention.
FIGS. 10A and 10B are explanatory diagrams showing examples of editing of image data after image editing.

In the example of FIG. 10A, since the keyword "according to Table 1" is included in the character information C19 of the first page, the enlarged graphic information D1 of Table 1 is rearranged near the character information C19. be.

In addition, in the example of FIG. 10B, since the keyword "according to Table 1" is included below the character information C20 on the second page, the enlarged graphic information of Table 1 is displayed near the character information C20. D1 is rearranged.

In this way, when enlarging and rearranging characters and graphics, a keyword indicating the graphics is extracted from the characters outside the graphics, and the graphics are rearranged within a predetermined range from the keywords. It is possible to realize the digital multifunction peripheral 1 that enlarges and displays even a document in which figures and tables are mixed so that the layout is easier to see than before.

[Embodiment 3]
<Image Editing Process of Digital MFP 1 According to Embodiment 3 of the Present Invention>
Next, image editing processing of the digital multi-function peripheral 1 according to Embodiment 3 of the present invention will be described with reference to FIGS. 11 and 12. FIG.

FIG. 11 is a flow chart showing an example of image editing processing of the digital multifunction peripheral 1 according to Embodiment 3 of the present invention.
11 correspond to steps S11 to S18 and S20 in FIG. 8 (embodiment 2), respectively, so description thereof will be omitted.

Here, the process of step S29 in FIG. 11, which is different from that of the second embodiment, will be described.

In step S27 of FIG. 11, if the enlarged figure is still smaller than the predetermined size (if the determination in step S27 is Yes), in step S29, the control unit 10 enlarges the figure to the entire page and creates an image of a new page. It is caused to output to the processing unit 14, and the information of the reference page of the original figure is output to the separate page (step S29).

FIG. 12 is an explanatory diagram showing an example of image editing processing of the digital multifunction peripheral 1 according to Embodiment 3 of the present invention.
FIGS. 12A and 12B are explanatory diagrams showing an example of editing of image data before image editing and after image editing, respectively.

The example of FIG. 12A has a two-column structure of character information C19 and C20.
However, it is assumed that the column structure cannot be canceled due to a predetermined setting.

In this case, it is impossible to enlarge the character information C1 to C18 in the graphic information D1 to a size that is easy to see without canceling the column setting. Output a new page.

In addition, as shown in FIG. 12B, "Table 1 (enlarged from the right column of the first page)" and the information of the reference page of the original figure are also output on the separate page.

In this way, even if the figure is enlarged, if the characters in the figure cannot be enlarged beyond the specified size, a new page with the figure enlarged to the entire page is output. Even if there is, it is possible to realize the digital multi-function peripheral 1 that enlarges and displays the layout so that it is easier to see than before.
