Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character size adjusting device for adjusting the character size of characters in an image, a character size adjusting method, and a recording medium on which a character size adjusting program is recorded.

[0002]

2. Description of the Related Art Conventionally, there has been an electronic typesetting technique as a technique used when creating a combination of image data and document data. This electronic typesetting technology is used for creating flyers and the like. According to this technique, image data and document data can be converted into appropriate sizes and arranged at desired positions. Therefore, an output (such as a flyer) combining the image data and the document data can be obtained only by arranging the image data and the document data based on a desired layout.

[0003]

However, when creating a flyer or the like using existing image data, the image size may be changed. For example, when considering a layout in consideration of the relationship with other image data or document data to be combined when creating a flyer, if the existing image data is used as it is, the image size may be large or conversely small. The image size may be reduced or enlarged. In addition, even if you simply want to output (print or display) an image of existing image data, not for the purpose of creating a flyer, reduce or enlarge the image size to match the size of the paper to be printed. Sometimes.

At this time, if the image data contains characters and the characters are held as images (graphics), when the image size is changed, the size of the characters in the image is changed according to the changed image size. Change. For this reason, when the image size is reduced, characters in the image may be crushed,
Conversely, when the image size is enlarged, the characters in the image become too large, and the consistency with the character size of the document data to be combined using the above-described electronic composition technology cannot be obtained.

Further, if the image data is image data of a format in which characters are stored as character data, even if the image size of the image data is changed, the size of the characters in the image data does not change (the image data does not change). The size of the figure inside changes.) Therefore, the balance between the graphic whose size has been changed and the character is lost.

When the image size of the image data including characters is changed, if the characters in the image do not have an appropriate size, the character size when the image size is changed to obtain a desired output is changed. There is a problem that the image data considered must be created again. In addition, image data must be created in consideration of the character size when the image size is changed, and there is a problem that it takes time to create the image data.

An object of the present invention is to provide a character size adjusting device capable of appropriately adjusting the size of characters in an image separately from the image size even when the image size of image data including characters is changed, An object of the present invention is to provide a character size adjusting method and a recording medium on which a character size adjusting program is recorded.

[0008]

The technical idea of the present invention is as follows.
When the image size of the image data including the character is changed, the character in the image is adjusted to a character of an appropriate size with good visibility separately from the image size.

The configuration of the present invention will be described below. (1) A character size adjusting apparatus according to the present invention includes a character extracting unit for extracting characters in an image from image data, and determining whether a character extracted by the character extracting unit has an appropriate size. There is provided a character size judging means for judging, and a character size adjusting means for replacing a character having an inappropriate size with a character having an appropriate size when there is a character having an inappropriate size (claim 1).

In this configuration, a character in an image is extracted from the image data, it is determined whether or not the character size of the character is appropriate, and a character having an unsuitable character size is converted into a character having an appropriate character size. replace. That is,
When changing the image size of image data including text,
Adjust the character size of the characters in the image separately from the image size. Therefore, even if the image size of the image data including characters is changed, it is possible to obtain image data (output) in which characters in the image are adjusted to an appropriate size with good visibility. In addition, when creating image data, there is no need to consider the character size when the image size is changed, and the image data can be easily created.

Here, the image data including characters is data having figures and characters. In addition, the format of image data includes a format in which characters are stored as character data,
There is a format that holds characters as graphic data.

(2) An image data extracting means for extracting image data from output data having image data and document data is provided.

With this configuration, image data can be extracted from output data having image data and document data, and characters in the image can be adjusted to an appropriate size with good visibility for the extracted image data.

Here, the document data is composed of character data, and the output data is a format in which image data and document data are combined, for example, HTML format data.

(3) The character size judging means is means for judging whether the character in the image data has an appropriate size by using the size of the character in the document data. .

With this configuration, it is determined whether or not the characters in the image data have an appropriate size using the size of the characters in the document data. Therefore, the characters in the image data can be adjusted to a size that is consistent with the characters in the document data.

(4) The image data is data held separately from graphic data and character data.

(5) The character size adjusting means includes means for changing a font.

With this configuration, when adjusting the character size, the font of the character can also be adjusted.

(6) The character size adjusting means includes means for changing the thickness of the character.

With this configuration, when adjusting the character size, the thickness of the character can also be changed.

(7) The character size judging means is means for judging that the character size is appropriate if it is within a predetermined size range (claim 7).

In this configuration, the characters in the image do not become smaller than a certain size (lower limit value). Therefore, when the image size is reduced, the characters do not become small and are not broken. Also, since the characters in the image do not become larger than a certain size (upper limit), the characters do not become too large when the image size is enlarged.

(8) The image data is a moving image.

With this configuration, for a moving image including text information such as movie subtitles and news, the above-described subtitles and text information can be output in an easily viewable manner.

FIG. 1 is a block diagram showing a functional configuration of a character size adjusting device according to an embodiment of the present invention. The character size adjusting device of this embodiment adjusts the size of characters in an image whose size has been changed separately from the image size when the image size of the image data is changed. In FIG. 1, reference numeral 1 denotes a character size adjusting device main body, 2 denotes an image input unit to which image data whose image size has been changed (image data before character size adjustment) is input;
Reference numeral 3 denotes a character extraction unit for extracting characters in the image input to the image input unit 2, reference numeral 4 denotes a character size recognition unit for recognizing the character size of the character extracted by the character extraction unit 3, and reference numeral 5 denotes a character size recognition unit 4. A character size adjustment unit that adjusts the character size for characters whose recognized character size is not appropriate,
Reference numeral 6 denotes an image output unit that outputs image data whose character size has been adjusted (image data after the character size adjustment).

Hereinafter, the operation of the character size adjusting device 1 of this embodiment will be described. Here, the following description will be made, taking as an example a case where the image size of the image data is changed. Changing the image size of image data is, for example, simply changing the image size to display or print the image, or changing the image size due to layout problems when using it for creating flyers etc. Conceivable.

FIG. 2 is a flowchart showing the processing of the character size adjusting apparatus according to this embodiment. In the character adjustment device 1 of this embodiment, when the image size of existing image data is changed, the image data whose size has been changed (hereinafter referred to as input image data) is input to the image input unit 2. Is done. When input image data is input to the image input unit 2 (n1), the character size adjusting device 1 extracts characters from the image of the input image data (n2). FIG.
Shows an example of input image data. This example is image data including an image of the main body of the automatic clearing machine and characters “automatic clearing machine”. The input image data holds the character "automatic clearing machine" as graphic data, and when the image size is reduced, the character "automatic clearing machine" is also reduced (characters are difficult to see). . The character extracting unit 3 extracts characters in the image from the input image data at n2. As a method for extracting characters in an image, character recognition software (so-called,
A method of extracting characters one by one using OCR software) and a method of extracting a character portion as image data are known. Here, using the OCR software, the character extracting unit 3 extracts characters in the input image data one by one.

The character size recognition unit 4 recognizes the character size (character size) for each character extracted from the input image data (n3). To recognize the font size,
For example, the diagonal length of the square portion occupied by the character may be detected as shown in FIG. 4A, or the vertical and horizontal lengths of the square portion shown by the character as shown in FIG. May be detected. The character size may be recognized based on the ratio of the character area to the entire image, the font size, and the like. In this embodiment, the character size is recognized from the length of the diagonal line of the square portion occupied by the character (FIG. 4).
The character size is recognized by the method shown in FIG. ). The character size recognizing unit 4 detects the length of the diagonal line of the rectangular portion occupied by each of the five characters “self”, “moving”, “clean”, “calculation”, and “machine” extracted from the input image shown in FIG. . Here, it is assumed that the size of each character (the length of the diagonal line of the square portion occupied by the character) is 3 mm.

The character size adjusting section 5 determines whether or not the character size is appropriate for each character recognized in n3 (n4). If the character size is not appropriate, the character size in the image input in n1 is determined. The corresponding character is adjusted to a character of an appropriate size (n5). If the characters are of appropriate size, n
Step 5 is not performed.

Next, a method for determining whether the character size is an appropriate size will be described. In the character size adjusting device 1 of this embodiment, if the length of the diagonal line of the square portion occupied by the character is 5 to 50 mm, it is determined that the size is appropriate, and if the length is less than 5 mm or exceeds 50 mm, the appropriate size is determined. It is determined that it is not. If the character is less than 5 mm, the diagonal length of the square portion occupied by the character is replaced with a character having a length of 5 mm. If the character exceeds 50 mm, the diagonal length of the square portion occupied by the character is 50 mm.
Replace with the character FIG. 5 shows the above-mentioned relationship between the character size before adjustment and the character size after adjustment (character size adjustment rules are shown).

As described above, the five characters "self", "movement", "clear", "calculation" and "machine" included in the image data input at n1 are the lengths of the diagonal lines of the square portions occupied by the characters. Is 3
mm (because it is not an appropriate size), the length of the diagonal line of the square portion occupied by the character at n5 is replaced (adjusted) by a character having a length of 5 mm. Then, the image output unit 6 outputs image data in which the character size of the characters in the image has been adjusted (hereinafter, referred to as output image data). If all the characters in the input image have an appropriate size, the input image data is output as output image data. If the character size exceeds 50 mm, it is replaced (adjusted) by a character of 50 mm.

FIG. 6 shows image data (output image data) in which the character size in the image has been adjusted. In the output image data in which the character size has been adjusted as shown in FIG. 6, the characters "automatic clearing machine" in the image are large and easy to see. The input image data and the output image data shown in FIGS. 3 and 6 have the same image size.

As described above, the character size adjusting apparatus 1 of this embodiment determines whether the character in the original image (input image) whose image size has been changed has an appropriate size,
If it is not an appropriate size, replace it with an appropriately sized character. Therefore, when the image size is reduced, the characters in the image do not become small and are not broken, and when the image size is enlarged, the characters in the image become too large, and the balance between the characters and the graphic in the image is reduced. There is no problem of collapse. Moreover, when the image size is changed, the size of the characters in the image is adjusted separately from the image size, so that when creating the image data, it is not necessary to consider the character size when the image size is changed. As a result, image data can be easily created.

In the above embodiment, characters are extracted from input image data using OCR. However, character regions are extracted from original image data before the image size is changed. A region corresponding to the character region extracted from the original image data may be extracted as a character region. With this configuration, when the image size is changed, even if the character in the input image whose image size has been changed is crushed, the character in the input image data is reliably extracted by the process of n2, It can be replaced with characters of an appropriate character size.

Further, in the above-described embodiment, characters that are not of an appropriate size are replaced with characters of an appropriate size. However, the font and thickness of the characters may be changed. The conditions for changing the font and thickness of the characters may be determined in advance, or the user may be allowed to specify whether to change the font and thickness. In addition, physical data such as the age and the visual acuity of the user may be input in advance, and an appropriate character size in the image data may be determined based on the physical data (for example, a user having a weaker visual acuity may be used). And increase the appropriate character size.). Further, in the above embodiment,
Although the original image has been described as a still image, a moving image including characters (a moving image including character information such as a movie or news with subtitles) may be displayed. it can.

Next, another embodiment of the present invention will be described. FIG. 7 is a block diagram showing a functional configuration of the character size adjusting device according to this embodiment. The character size adjusting device 1 of this embodiment has the configuration shown in FIG.
An output data input unit 11 to which output data composed of image data and document data is input, an image / document data separation unit 12 for separating image data and document data from output data input to the output data input unit 11, and The document data separated by the image / document data separation unit 12 is input, a document-side character size recognition unit 13 that recognizes the size of characters in the document data, and an output data synthesis unit that synthesizes image data and document data. 14 is provided. The image data separated by the image / document data separation unit 12 is input to the image input unit 2, and the document data is input to the document-side character size recognition unit 13.

The character size adjusting device 1 of this embodiment
When outputting (displaying and the like) image data and document data together, the size of the characters in the image data is adjusted in conjunction with the size of the characters in the document data. That is, it has a function of matching the size of characters in image data to be output together with the size of characters in document data. As output data for outputting image data and document data together, for example, there is output data that can be viewed with a browsing tool on the Internet.

Hereinafter, the operation of the character size adjusting apparatus 1 according to this embodiment will be described. FIG. 8 is a flowchart showing the processing of the character size adjusting device of this embodiment. When output data including image data and document data is input to the output data input unit 1 (n11), the character size adjusting device 1 separates image data and document data from the input output data (n12). . FIG. 9 shows an example of an image of the input output image data. This output data is output data in which an image of the main body of the automatic clearing machine and image data including the characters "automatic clearing machine" are combined with document data on the right side of the image data. As such output data combining image data and document data, there is an HTML format file shown in FIG. In the case of HTML format, image data (pk3.jp
g) and the document data can be easily separated. However, by providing the image / document data separation unit 12 with a function of separating the image data and the document data from the output data input at n11, even if the output data is a file in a format other than the HTML format, And document data can be separated.

When the output data is separated into image data and document data in n12, the document-side character size recognition unit 13 recognizes the character size of the separated document data (n1).
3). As described above, there are various methods for recognizing the character size. In this case as well, the diagonal length of the square portion occupied by the character is recognized as the character size (FIG. 4).
(Method shown in (A)). Here, it is assumed that the character size of the document data is 11 mm. The character size adjusting device 1 extracts characters ("automatic clearing machine") in the image from the image data input to the image data input unit 2 in the same manner as in the above-described embodiment (n14). Then, the character size of the character is recognized (n15). Here, it is assumed that the character size in the image data is 7 mm. Then, the character size adjusting unit 5 adjusts the character size of the image data based on the recognized character size of the document data and the character size of the image data (n16, n17).

Hereinafter, a method for adjusting the character size in the image data will be described. In this embodiment, the character size of the image data may be adjusted by the method shown in FIG. 5, but the character size of the image data is adjusted based on the character size of the document data. First, the character size adjustment unit 5
A character size adjustment rule corresponding to the difference between the character size of the document data and the character size of the image data and the ratio of increasing the character size of the image data is set (the character size adjustment rule shown in FIG. 11). Is set.) In FIG. 11, the horizontal axis represents the difference between the character size of the document data and the character size of the image data, and the vertical axis represents the size added to the characters of the image data. According to the character size adjustment rule shown in this figure, for example, if the difference is 10 mm, the character size of the image data is increased by 7 mm, and if the difference is 4 mm, the character size of the image data is 2 m.
m plus size.

In the example of the output data shown in FIG. 9, since the character size of the image data is 7 mm and the character size of the document data is 11 mm, the character size adjusting unit 5 adds the character size of the image data by 2 mm ( 9m
Replace with the letter m. Then, the output data synthesizing unit 14
In, the document data and the image data obtained by adjusting the character size in the image are synthesized and output (n18). FIG.
Reference numeral 2 denotes an image of output data (output data output at n18) in which the character size in the image data has been adjusted. As shown in FIG. 12, the output is easy to see as a whole by adjusting the character size in the image data.

As described above, in this embodiment, not only the character size of the image data is simply increased, but also the image data is adjusted in conjunction with the character size of the document data to be output together. Moreover, since the difference between the character size of the document data and the character size of the image data is reduced,
The characters of the document data and the characters of the image data can be matched, and an output with good visibility as a whole can be obtained.

In the above-described embodiment, the character size adjustment rule shown in FIG. 5 or FIG. 11 is set in the character size adjustment unit 5, but the character size adjustment rule is added to the image data. Can also. Hereinafter, image data creation software capable of creating image data having a character size adjustment rule will be described. FIG.
5 is a flowchart showing processing of image data creation software. The image data creation software determines whether the data currently created is a character (n21),
If it is a character, a character size adjustment rule is set (n2
2). As the character size adjustment rule, the rule shown in FIG. 5 or FIG. 11 may be set.
May be set in combination.

As described above, in the image data creation software of this embodiment, the created data is provided with the character size adjustment rule, so that the created image data can be provided with the character size adjustment rule. it can. When the image size is changed, the character size adjustment rule of the image data may be read by the character size adjustment unit 5 and the character size of the image data may be adjusted.

Next, another embodiment of the present invention will be described. The character size adjusting apparatus 1 of this embodiment adjusts the character size in an image when the image size is changed for image data in a format in which characters are stored as character data. FIG. 15 is a diagram illustrating an example of output of image data in which characters are stored as character data. The image data shown in FIG. 15 includes one graphic data A and two character data B, and these graphic data A and character data B
, The arrangement, character size, decoration, etc. are set.

FIG. 16 is a block diagram showing a functional configuration of the character size adjusting apparatus of this embodiment. The character size adjusting apparatus 1 of this embodiment includes an image data input unit 21 to which image data is input, a graphic size recognition unit 22 that recognizes a graphic size in the input image data, a character size in the input image data. Character size recognition unit 2 that recognizes
3. It has a character size adjusting unit 24 for adjusting the character size of characters in the image data, and an image data output unit 25 for outputting image data with the adjusted character size.

The operation of the character size adjusting apparatus according to this embodiment will be described below. FIG. 17 is a flowchart showing the operation of the character size adjusting device of this embodiment. In the character adjustment device 1 of this embodiment, when the image size of the image data is changed, the image data (hereinafter, referred to as input image data) is input to the image input unit 21. When the input image data is input to the image input unit 21 (n31), the character size adjustment device 1 recognizes the image size (the changed image size) of the input image data (n).
32).

Here, since the input image data is in a format in which characters are stored as character data as described above, the character size does not change. For example, if the image size of the image data shown in FIG.
As shown in the figure, the figure data A is smaller, but the character data B is not changed (not reduced). Further, since the graphic data A and the character data B are held separately, the graphic data A and the character data B can be easily separated and extracted from the image data. In n32, the ratio between the image size before the size change and the image size after the size change is recognized. Here, it is assumed that the input image data has been reduced to 50%.

Next, the character size of the character data held by the input image data is recognized (n33). The method of recognizing the character size is based on the length of the diagonal line of the rectangular portion occupied by the character, as in the above-described embodiment. here,
Character size 1 for character data B "new product information"
6 mm, character data B “electronic thermometer ... 200
For "0 yen", it is assumed that the character size is 7 mm.
The character size adjustment unit 24 replaces the character data with characters of an appropriate size based on the image size recognized at n32 and the character size recognized at n33 (n34, n3).
5).

Hereinafter, a process for adjusting the character size will be described. In the character adjustment device 1 of this embodiment, a character size adjustment rule for reducing the character size in the image data at the same ratio as the image size is set (see FIG. 19). In this example, since the image size is reduced to 50%, the character size is also reduced to 50%. As a result, the character size of the character data B “new product information” becomes 8 mm, and the character data B “electronic thermometer.
"00 yen" has a character size of 3.5 mm. Here, if the character data in the image data is replaced based on the above rule, only the characters in the image data are changed at the same reduction (or enlargement) rate as the image size.
As shown in FIG. 20, character data B “electronic thermometer... 200
This is an image in which characters about "0 yen" are small and difficult to see.

In the character size adjusting apparatus 1 of this embodiment, the character data B "electronic thermometer... 2000 yen" is replaced with a character having a character size of 5 mm based on the character size adjusting rule shown in FIG. 7mm (appropriate size) for character data B "new product information"
Is not adjusted. ). As a result, the output image data is output as shown in FIG. 21, and the character data B “electronic thermometer... 2000 yen” can be displayed in an easily viewable size.

As described above, in the character size adjusting apparatus according to the present embodiment, even if the image data is in the format in which the character data and the graphic data are separately stored, the image data is changed when the image size is changed. Can be adjusted to an appropriately sized character.

Next, another embodiment of the present invention will be described. In this embodiment, when image data and document data are output together, the size of the characters in the image data is adjusted in conjunction with the size of the characters in the document data. That is, the size of the character in the image data to be output together is matched with the size of the character in the document data. Here, the image data has a format in which characters are stored as character data, and the output data is a file in an HTML format.

The character size adjusting device 1 of this embodiment has the configuration shown in FIG. FIG. 22 is a flowchart showing the processing of the character size adjusting device of this embodiment. Output data including image data and document data is input to the character size adjustment device 1 of this embodiment. When the output data including the image data and the document data is input to the output data input unit 11, the character size adjusting device 1 (n)
41), image data and document data are separated from the input output data (n42). FIG. 23 shows an image of the output data. The output data includes the graphic data A of the electronic thermometer, “new product information” and “electronic thermometer... 20”.
This is an HTML format file including image data composed of character data B of "00 yen" and document data.

When the output data is separated into image data and document data in n42, the document-side character size recognition unit 33 recognizes the character size of the separated document data (n4).
3). As described above, there are various methods for recognizing the character size, but also in this case, the length of the diagonal line of the square portion occupied by the character is recognized as the character size.
Here, the character size of the recognized document data is 12 mm.
Assume that In addition, the characters (“new product information” and “electronic thermometer... 2”) in the image data for the image data input to the image data input unit 2 are similar to the above-described embodiment.
000 yen ”) is extracted (n44), and the character size of the extracted character is recognized (n45). Here, "New Product Information"
Is 10mm, "Electronic thermometer ... 2000 yen" is 5mm
Assume that

The character size adjusting section 5 adjusts the characters in the image data based on the character size of the document data (n4
6, n47). In this embodiment, a method of increasing the character size in case the size of the character data itself is too small (an adjustment method using the character size adjustment rule shown in FIG. 5) and a comparison with the character size of the document data The character size of the characters in the image data is adjusted using a method of storing the difference between the character sizes (an adjustment method using the character size adjustment rule shown in FIG. 11). Specifically, the character size adjustment unit 5 first adjusts the character size based on the character size adjustment rule shown in FIG. Here, "new product information" is 10 mm, "electronic thermometer ... 2
Since “000 yen” is 5 mm, the character size of the character in the image data is not changed by the character size adjustment rule shown in FIG. Then, the character size is adjusted based on the character adjustment rule shown in FIG. Here, the character data B "new product information" is replaced by 11 mm characters, and the character data B "electronic thermometer ... 2000 yen" is replaced by 9 mm characters. Then, the image data with the adjusted character size is output (n48), and this processing ends.

FIG. 24 shows an output example in which the character size is adjusted for the characters in the image data. As shown in FIG. 24, the difference between the characters in the image data and the characters in the document data is small, and the output is easy to see as a whole. in this way,
In the character size adjusting apparatus 1 of this embodiment, the characters in the image data can be adjusted to a size that matches the character size of the document data, and an output that is consistent as a whole can be obtained.

Next, another embodiment of the present invention will be described. 2. Description of the Related Art Conventionally, there is an application that displays an explanation or the like regarding a button 31 on which a cursor is placed when the cursor is placed on a button 31 displayed as an image on a display screen. More specifically, when the cursor is positioned on the button 31 while the display screen shown in FIG. 25 is displayed, as shown in FIG. There is an application that displays. The size (character size) of the displayed character at this time is generally fixed (set in the system or the like), and FIG.
In some cases, the character size is small and difficult to see as shown in FIG.
The character size adjusting device 1 of this embodiment adjusts the character size when displaying text data (explanatory text 32 related to a button on which a cursor is placed) attached to image data. The description 32 is a character in the image data. The related document is document data output together with the image data.

FIG. 27 is a block diagram showing a functional configuration of a character size adjusting device according to an embodiment of the present invention.
