  The present invention relates to an information processing device, a display change method, and a display change program, and more particularly to an information processing device, a display change method, and a display change program that can further improve the visibility of characters on a screen.

  Conventionally, in an information processing apparatus such as a personal computer, characters on the screen may be displayed in a small size. In particular, it may be difficult for seniors or low-sighted people to recognize characters.

  In such a case, for example, the user performs an operation for improving the visibility of characters on the screen by changing the screen resolution and enlarging the characters. Here, as a method for improving the visibility of characters on the screen, for example, Patent Document 1 discloses a technique for changing the font size of characters on the screen according to the distance from the screen to the position of the user's face. Has been.

JP-A-10-260666

  However, on the screen of the information processing apparatus, there are cases where small characters and large characters are mixedly displayed, and if the character size is enlarged by the above method, the visibility is adversely affected. There is a fear. That is, when the conventional method is used, since the entire screen is enlarged, there is a possibility that characters that are originally large in size become too large to be visually recognized. In addition, since the entire screen is enlarged and displayed, the number of characters and images that can be displayed on one screen is reduced, so that there are cases where scrolling operations up and down and left and right are necessary to read a sentence.

  The disclosed technology has been made to solve the above-described problems caused by the prior art, and provides an information processing device, a display change method, and a display change program that can further improve the visibility of characters on the screen. The purpose is to do.

  In order to solve the above-described problems and achieve the object, an information processing apparatus disclosed in the present application has a character recognition unit that recognizes a character included in an image area, and a character size recognized by the character recognition unit. Character determining means for determining, and character changing means for enlarging the character to the predetermined size when the character determining means determines that the size of the character is smaller than a predetermined size.

  According to the information processing apparatus, the display change method, and the display change program disclosed in the present case, it is possible to further improve the visibility of characters on the screen by enlarging only characters smaller than a predetermined size. .

  Exemplary embodiments of an information processing apparatus, a display change method, and a display change program disclosed in the present disclosure will be described in detail below with reference to the accompanying drawings.

  First, an overview of an information processing apparatus according to the present embodiment will be described with reference to the drawings. 1 is a block diagram showing the configuration of an information processing apparatus according to the present embodiment, FIG. 2 is a diagram showing an example of a setting information management table according to the present embodiment, and FIG. 3 is a diagram of a color conversion rule management table according to the present embodiment. It is a figure which shows an example. 4A is a diagram illustrating an example of characters and images in the image area before the character conversion process, and FIG. 4B is a diagram illustrating an example of characters and images in the image area after the character conversion process. is there.

  In this embodiment, the information processing apparatus is a notebook personal computer. However, the information processing device is not limited to this, and may be another terminal device such as a desktop personal computer, a portable terminal device, or a PDA (Personal Digital Assistant).

  As shown in FIG. 1, the information processing apparatus 1 according to the present embodiment includes a display unit 10, an operation unit 11, an audio processing unit 12, a communication unit 13, a storage unit 14, an I / O 15, and a power source. Unit 16 and control unit 17.

  The display unit 10 is a liquid crystal display, for example, and displays various images. The operation unit 11 is, for example, a keyboard or a touch pad, and receives an operation from the user of the information processing apparatus 1. In particular, the operation unit 11 includes a display change mode switching button, and receives an instruction from the user as to whether or not to perform a character change process or the like by a display data processing unit 172 described later. The audio processing unit 12 performs D / A (Digital / Analog) conversion of the audio data into an analog audio signal, and outputs the audio signal as a sound wave to a speaker (not shown). The communication unit 13 is hardware for connecting to a network such as a public line, the Internet, or a LAN (Local Area Network).

  The storage unit 14 functions as a storage unit and stores various types of information. In particular, the storage unit 14 includes a character data storage area 141, a setting information management table 142, and a color conversion rule management table 143. The character data storage area 141 stores character data of various sizes, fonts (typefaces), thicknesses, and colors. Here, in this embodiment, the characters include symbols, numbers, alphabets and the like in addition to hiragana characters, katakana characters, and kanji.

  The setting information management table 142 manages setting information required when the display data processing unit 172 performs character change processing. Specifically, as shown in FIG. 2, the setting information management table 142 stores character size, thickness, and font setting information. For example, in FIG. 2, the character size is set to “16 points”, the character thickness is set to “1.5 points”, and the font is set to “MS Gothic”. These pieces of setting information are used when a character change process described later is performed. The user can change the setting information by operating the operation unit 11. In this embodiment, the character size and thickness means the physical size and thickness of the character displayed on the display unit 10.

  As shown in FIG. 3, the color conversion rule management table 143 stores a combination of a background color and a character color in association with a character color to be changed when the combination is the combination. For example, the combination of the background color “white” and the character color “yellow” is associated with “green” as the changed character color. This color conversion rule management table 143 is used when a character color change process described later is performed. The storage unit 14 stores various applications such as a text editor and a web browser that can edit the text editing file.

  The I / O 15 is an interface used when inputting / outputting information to / from an external device connected to the information processing apparatus 1. The power supply unit 16 supplies power to each device in the information processing apparatus 1.

  The control unit 17 controls the entire information processing apparatus 1. In particular, the control unit 17 includes a display data generation unit 171 and a display data processing unit 172. The display data generation unit 171 generates display data of an image to be displayed on the display unit 10 based on information acquired from the operation unit 11, the communication unit 13, the storage unit 14, the I / O 15, and the like.

  For example, the display data generation unit 171 generates display data to be displayed on the display unit 10 based on a text editing file executed by a user's operation on the operation unit 11 or web data acquired via the network by the communication unit 13. Generate. Here, the display data according to the present embodiment includes all images displayed on the display unit 10. That is, the image based on the display data indicates not only a text editing file and a Web page (including a window image) but also everything displayed on the display unit 10 such as a desktop image background, icon, and toolbar. In this embodiment, the display data is bitmap data. The desktop image refers to an image excluding windows generated by various applications among images displayed on the display unit 10.

  The display data processing unit 172 performs a process for changing the display data generated by the display data generation unit 171. Specifically, the display data processing unit 172 performs a character conversion process that improves the visibility of characters included in the display data. For example, as shown in FIG. 4A, “***”, “Kakukoku Sashisuseso”, “Small 1 Small 2” included in the image based on the display data generated by the display data generation unit 171. It is assumed that the size of each character of “...” is smaller than the size of the character set in the setting information management table 142 shown in FIG. In such a case, the display data processing unit 172 improves the visibility of the sentence by enlarging these characters as shown in FIG.

  In addition, as illustrated in FIG. 4A, the display data processing unit 172 determines that the font of each character “ABCD” is different from the font set in the setting information management table 142 (here, MS Gothic). -2, change the font of these characters to MS Gothic. In addition, when the characters “aiueo” are difficult to see in relation to the background color as shown in FIG. 4-1, the display data processing unit 172 displays these characters according to the background color as shown in FIG. Change to a color that is easy to see.

  Furthermore, the display data processing unit 172 performs not only an image displayed based on various applications but also a process of changing characters included in an image displayed on a desktop image such as a toolbar or an icon. That is, as shown in FIGS. 4A and 4B, the display data processing unit 172 performs enlarged display of each character such as “◇ Start” and “10:30”. In addition, as shown in FIG. 4A, the display data processing unit 172 has a character width of “◇ start” or “10:30” smaller than the thickness set in the setting information management table 142. As shown in FIG. 4B, these characters are changed to a predetermined thickness.

  Hereinafter, a more specific configuration of the display data processing unit 172 will be described with reference to FIG. FIG. 5 is a block diagram illustrating the configuration of the display data processing unit 172 according to the present embodiment, and FIG. 6 is a diagram illustrating another example of the setting information management table according to the present embodiment. As shown in FIG. 5, the display data processing unit 172 includes a character recognition unit 101, an image recognition unit 102, a character determination unit 103, a background color recognition unit 104, an image forming unit 105, and a display control unit 106. Have

  The character recognition unit 101 functions as a character recognition unit and recognizes characters included in the image area. Here, the image region indicates an image region based on display data generated by the display data generation unit 171. For example, when the image based on the display data generated by the display data generation unit 171 is an image as shown in FIG. 4A, the character recognition unit 101 displays “ABCD”, “****”, "," Kekikuko ... "," Large "," Small 1 Small 2 ... "," ◇ Start "and" 10:30 "are recognized as characters.

  The image recognition unit 102 functions as an image recognition unit, and recognizes an image included in the image area. For example, when the image based on the display data generated by the display data generation unit 171 is an image as shown in FIG. 4A, the image recognition unit 102 uses a circle 70, a frame (straight line) 80, or the like as the image (FIG. 4-1). The character determination unit 103 functions as a character determination unit, and determines the size of the character recognized by the character recognition unit 101. In addition, the character determination unit 103 determines not only the character size but also the character color, font, and thickness.

  The background color recognition unit 104 determines the background color of the image area. Here, the background refers to a region other than a portion recognized as a character and an image in the image region. In this embodiment, the background color recognition unit 104 recognizes the background color for each character recognized by the character recognition unit 101. Specifically, the background color recognition unit 104 recognizes the color around each character as the background color of the character. Note that in the display change mode, the background image (standby image), the toolbar, the start menu, and the like constituting the desktop image are displayed as predetermined images. In addition, the characters displayed on the desktop image are also displayed with a predetermined size, color, and thickness.

  The image forming unit 105 functions as a character changing unit. When the character determining unit 103 determines that the character size is smaller than a predetermined size, the image forming unit 105 enlarges the character to a predetermined size. That is, when the size of characters included in the display data generated by the display data generation unit 171 is smaller than the size set in the setting information management table 142, the image forming unit 105 Processing to change the character size to the set size is performed. For example, as illustrated in FIG. 4A, when it is determined that the size of each character “small 1 small 2...” Is smaller than the size “16 points” set in the setting information management table 142, the image forming unit. 105 changes the physical size (actual size displayed on the display unit 10) of each character to 16 points.

  Further, the image forming unit 105 functions as a character changing unit, and when the thickness of the character determined by the character determining unit 103 is thinner than a preset thickness, the thickness of the character is set in advance. Change to thickness. That is, when the thickness of the character included in the display data is smaller than the thickness set in the setting information management table 142, the image forming unit 105 sets the character thickness for the display data. Perform processing to change the thickness. For example, as illustrated in FIG. 4A, when it is determined that the thickness of each character “10:30” is thinner than the thickness “1.5 points” set in the setting information management table 142, the image forming unit 105 Changes the thickness of each character to “1.5 points”. The thickness of the character also means the thickness of the character when it is actually displayed on the display unit 10.

  Similarly, the image forming unit 105 functions as a character changing unit, and when the font of the character determined by the character determining unit 103 is different from a preset font, the font of the character is changed to a preset font. change. That is, when the font of the character included in the display data is different from the font set in the setting information management table 142, the image forming unit 105 sets the thickness of the character for the display data to the set thickness. The process to change is performed. For example, as illustrated in FIG. 4A, when it is determined that the font of each character “ABCD” is “MS Mincho” and is different from the font “MS Gothic” set in the setting information management table 142, image formation is performed. The unit 105 changes the font of each character to “MS Gothic”.

  Note that the font of the character may differ depending on the character type (kanji, symbol, number, etc.). Therefore, when changing the font, the image forming unit 105 may change the changed font to a font corresponding to the character type. In such a case, as shown in FIG. 6, the setting information management table 142 sets font setting information for each character type. In addition, the character determination unit 103 determines not only the character font but also the character type. If the font of the character is different from the font corresponding to the character type, the image forming unit 105 changes the font of the character to a font corresponding to the character type. Thereby, the font of a character can be changed into the font according to the kind of the said character, and the visibility of a character can be improved further.

  Here, the character changing process will be described more specifically. First, the image forming unit 105 deletes the character determined by the character determining unit 103 from the display data. Next, the image forming unit 105 is character data corresponding to the deleted character among the character data stored in the character data storage area 141 of the storage unit 14, and the size set in the setting information management table 142. Extract character data of font and thickness. Then, the character size, thickness, or font is changed by assigning the extracted character data to the position where the deleted character was displayed.

  If the character size is changed so that it overlaps with another adjacent character, the image forming unit 105 determines that the character extracted from the character data storage area 141 is not a position where the deleted character is displayed but a predetermined character. Assign a character spacing. Thereby, it can prevent that a character overlaps after a character change. Moreover, you may perform a character change process per character string. That is, for example, when the character string “Aiueo” is enlarged, the position is adjusted so that each character does not overlap with “A” as a base point. As a method of determining a character string, for example, the determination is made based on an interval between characters. In other words, the image forming unit 105 determines that characters adjacent to each other at an interval narrower than a predetermined character interval are one character string.

  The image forming unit 105 functions as a character changing unit, and the combination of the background color determined by the background color recognition unit 104 and the character color determined by the character determination unit 103 is a color conversion rule management in the storage unit 14. When the combination corresponds to the combination stored in the table 143, the color of the character is changed based on a predetermined conversion rule. That is, when the combination of the character color included in the display data and the background color around the character corresponds to the combination stored in the color conversion rule management table 143, the image forming unit 105 determines the character color. To the color associated with the combination.

  For example, as illustrated in FIG. 4A, when the color of each character “Aiueo” is “yellow” and the background color around each character is “white”, the image forming unit 105 It is determined whether or not the combination is stored in the color conversion rule management table 143. If it is determined that the combination is stored in the color conversion rule management table 143, the image forming unit 105 uses the color stored in the color conversion rule management table 143 in association with the combination. Change to a certain “green”.

  In the display change mode, the background color and the character color may be uniformly changed to predetermined colors. That is, the image forming unit 105 changes the color of the character recognized by the character recognizing unit 101 to a predetermined color (for example, white) in the image area, and the character and the image recognized by the image recognizing unit 102. The color of the part other than (ie, background) is changed to a predetermined color (for example, black). As a result, it is not necessary to recognize the background color or determine the character color after the change for each character, and the time required for processing can be shortened.

  Further, the image forming unit 105 checks whether or not the layout of the entire image based on the display data is distorted with respect to the display data after the character size is changed by the character changing unit. If so, adjust the layout. Hereinafter, the layout adjustment process will be specifically described. FIG. 7A is a diagram illustrating an example of characters and images in the image area before the character conversion process, and FIG. 7B is a diagram illustrating an example of characters in the image area overlapping with the image after the character conversion process. FIG. 7C is a diagram illustrating an example of characters and images in the image area after layout adjustment processing.

  The image forming unit 105 functions as a layout determination unit, and whether or not the character recognized by the character recognizing unit 101 overlaps the image recognized by the image recognizing unit 102 in the image area after the character change by the image forming unit 105. Determine whether. If it is determined that the character overlaps with the image, the image forming unit 105 functions as a layout adjustment unit, and changes the position of the character to a position that does not overlap the image.

  For example, as shown in FIG. 7A, in the image area 30 before the character change process, each character of “Aiue Okaki Kukeko” was displayed on the left side of the image 40. Assume that some of these characters overlap the image 40 as shown in FIG. In such a case, the image forming unit 105 functions as a layout determination unit, and determines that the character “Kakikukeko” overlaps the image 40 among the characters. The image forming unit 105 functions as a layout adjustment unit, and moves the characters to an area between the image 40 and the right end of the image area 30 so that the characters do not overlap the image 40.

  Specifically, as illustrated in FIG. 7C, the image forming unit 105 changes the position of these characters so that the character “Kakikukeko” overlapping the image 40 is positioned on the right side of the image 40. . That is, the image forming unit 105 first changes the position of “ka” to the right end of the image 40. Next, the image forming unit 105 changes the position of “ki” so as to be positioned on the right side of “ka”. Similarly, the image forming unit 105 sequentially changes the positions so that “ku”, “ke”, and “ko” are positioned to the right of “ki”, “ku”, and “ke”, respectively. As a result, as shown in FIG. 7C, the position of “Kakikukeko” is changed to the right side of the image 40, so that it is possible to prevent a decrease in visibility due to these characters overlapping the image 40.

  In this process, the character “Kakikukeko” overlapping the image 40 may be processed as one character string. That is, when the image forming unit 105 recognizes “Aiue Okeki Keko” as one character string, the first letter “Ka” after the character “Kaki” that overlaps with the image 40 is used as one character. Judge as a column. Then, the image forming unit 105 collectively moves “Kakikukeko” determined as one character string to the right side of the image 40. Thereby, processing can be simplified.

  Further, as another example of the layout adjustment process, a process when a character protrudes from the image area after layout adjustment will be described. FIG. 8A is a diagram showing how characters in the image area protrude from the image area after layout adjustment processing, FIG. 8B is a diagram showing how the image area is expanded as layout adjustment processing, and FIG. It is a figure which shows a mode that the character after a character change is reduced as adjustment processing.

  For example, as illustrated in FIG. 8A, it is assumed that each character of “Suseso” protrudes from the image region 30 as a result of performing the layout adjustment processing so that “Aiueokaki Kakusashi Suseso” does not overlap the image 40. . In such a case, the image forming unit 105 first determines that each character has protruded from the image area 30 by the layout determination unit. Then, the image forming unit 105 functions as a layout adjusting unit, and as illustrated in FIG. 8B, the image region 30 is expanded so that characters that protrude from the image region 30 are included in the image region 30. To do. Accordingly, the user can cause the display unit 10 to display the character “Suseso” that protrudes from the image region 30 by performing a scroll operation using the operation unit 11.

  In addition, when the character after layout adjustment protrudes from the image area 30, the image forming unit 105 may reduce the size of the protruding character and other characters included in the character string to which the character belongs. That is, as shown in FIG. 8A, when each character of “Suseso” protrudes from the image area 30, as shown in FIG. The size of each character of “Sashisuseso” is reduced to a size that allows all these characters to fit within the image area 30.

  As described above, after the character position is changed by the layout adjusting unit, the image forming unit 105 reduces the size of the character so that it fits in the image region when the character protrudes from the image region. Thereby, the visibility of a character can be improved, preventing collapse of a layout. Further, the user can cause the display unit 10 to display the character “Suseso” that protrudes from the image region 30 without performing a scroll operation.

  As another example of the layout adjustment process, a process when a character in the table protrudes from the frame due to the layout adjustment will be described. FIG. 9A is a diagram illustrating an example of a table before the character change process, FIG. 9B is a diagram illustrating an example of a case where characters in the table protrude from the frame after the character change process, and FIG. It is a figure which shows an example of the table | surface after.

  As shown in FIG. 9A, “Sample”, “Temple”, “Example 1”, “Aiueo”, “Tatsutoto”, “Example 2”, “123” are included in the table 50 included in the image area. , “456” are included, and it is assumed that “Aiueo” and “Tatsuteto” protrude from the frame as shown in FIG. In such a case, the image forming unit 105 first functions as a layout determination unit, and determines whether each character in the table 50 overlaps the frame after the character change process. If it is determined that “O” of “Aiueo” and “To” of “Tatsuteto” are out of the frame, the image forming unit 105, as shown in FIG. By narrowing the space between each “Tatetsuto” character, the characters are placed within the frame. As described above, when the layout determination unit determines that the character overlaps with the image, the image forming unit 105 narrows the space between the character and the adjacent character, thereby reducing the overlap between the character and the image. Can be prevented while maintaining.

  In addition, it is good also as reducing a character to the magnitude | size which fits in a frame instead of narrowing a character space | interval as mentioned above. That is, if the character string does not fit within the frame even if the character spacing is reduced, the image forming unit 105 reduces the size of each character in the character string to fit within the frame, thereby placing the character string within the frame. Can fit. Such processing may be performed after performing processing for narrowing the character spacing, or may be performed independently.

  Further, when the position of the character is changed by the character change process, the display data processing unit 172 determines whether the combination of the character color and the background color corresponds to the predetermined combination stored in the color conversion rule management table 143. May be determined again, and if the predetermined combination is satisfied, the color of the character may be changed. Of the various layout adjustment processes described above, which process is to be performed can be arbitrarily determined by the user by operating the operation unit 11.

  The display control unit 106 performs display control for displaying the display data generated by the display data generation unit 171 or the display data changed by the image forming unit 105 on the display unit 10.

  Next, specific operations of the information processing apparatus 1 according to the present embodiment will be described with reference to the drawings. FIG. 10 is a flowchart illustrating an example of a processing procedure of the information processing apparatus 1 according to the present embodiment. The following processing shows only processing related to character change processing and layout adjustment processing for display data among various operations executed by the information processing apparatus 1.

  As shown in FIG. 10, the display data processing unit 172 of the information processing apparatus 1 performs a character change process (step S11). This character change process is a process from steps S21 to S29 in FIG. 11, and will be described later. Subsequently, the image forming unit 105 performs layout adjustment processing (step S12). This layout adjustment processing checks whether or not the layout of the entire image based on the display data is distorted with respect to the display data after the character size is changed by the character change processing in step S11. In this case, the layout is adjusted. For example, when the character enlarged by the character change process overlaps with the image as the layout adjustment process, the image forming unit 105 changes the position of the character to a position that does not overlap with the image.

  Subsequently, the display control unit 106 converts the display data after the character change process or the layout adjustment process into image data (step S13), and outputs the image data to the display unit 10 (step S14).

  Next, the character change process in step S11 will be specifically described with reference to FIG. FIG. 11 is a flowchart illustrating an example of a processing procedure of character change processing according to the present embodiment.

  As shown in FIG. 11, when the character change process is started, the character recognition unit 101 recognizes characters included in the image area of the display data generated by the display data generation unit 171 (step S21). Subsequently, the character determination unit 103 determines whether or not the character recognized in step S21 is smaller than the specified size (step S22). This determination is made based on whether or not the size of the character is smaller than the size set in the setting information management table 142. In this process, when it is determined that the character recognized in step S21 is smaller than the designated size (Yes in step S22), the image forming unit 105 enlarges the character to the designated size (step S23). That is, the image forming unit 105 enlarges the size of the character to the size set in the setting information management table 142.

  When the process of step S23 is completed, or when the character recognized in step S21 in step S22 is not smaller than the specified size (No in step S22), the image forming unit 105 moves the process to step S24. In step S24, the character determination unit 103 determines whether the font of the character recognized in step S21 is the designated font set in the setting information management table 142. In this process, when the font of the character recognized in step S21 is not the designated font (No in step S24), the image forming unit 105 changes the font of the character to the designated font (step S25).

  Subsequently, the character determination unit 103 determines whether or not the thickness of the character recognized in step S21 is thinner than the thickness specified in the setting information management table 142 (step S26). In this process, when it is determined that the character recognized in step S21 is thinner than the designated thickness (Yes in step S26), the image forming unit 105 changes the thickness of the character to the designated thickness (step S27). When the processing in step S27 is completed, or when the thickness of the character recognized in step S21 in step S26 is not thinner than the thickness specified in the setting information management table 142 (No in step S26), the image forming unit 105 Shifts the processing to step S28.

  In step S28, the display data processing unit 172 performs a character color change process. This character color changing process is a process of changing the character color to a color that is easy to visually recognize according to the background color. This character color changing process is a process from steps S31 to S33 in FIG. 12, and will be described later. When this process ends, the display data processing unit 172 ends the character change process.

  Next, the character color changing process in step S28 will be specifically described with reference to FIG. FIG. 12 is a flowchart illustrating an example of the processing procedure of the character color changing process according to the present embodiment.

  As shown in FIG. 12, when the character color changing process is started, the background color recognition unit 104 recognizes the background color (step S31). Specifically, the background color recognition unit 104 recognizes the color around the character recognized in step S21 as the background color. Subsequently, the image recognition unit 102 determines whether the combination of the character color and the background color recognized in step S21 is stored in the color conversion rule management table 143 or a predetermined combination (step S32). ). In this process, when it is determined that the combination of the color of the character and the background color is a predetermined combination (Yes at step S32), the image forming unit 105 determines the color of the character in the color conversion rule management table 143. The color is changed to the color associated with (step S33).

  When the process of step S33 is completed, or when the combination of the character color and the background color recognized in step S21 in step S32 is stored in the color conversion rule management table 143 or is not a predetermined combination (No in step S33) ), The display data processing unit 172 ends the character color changing process.

  By the way, the various processes described in the above embodiments can be realized by executing a program prepared in advance on a computer. In the following, an example of a computer that executes a display change program having the same function as that of the information processing apparatus 1 shown in the above embodiment will be described with reference to FIG. FIG. 13 is a diagram illustrating a computer that executes a display change program.

  As shown in FIG. 13, a computer 500 as the information processing apparatus 1 is configured by connecting an HDD 510, a CPU 520, a ROM 530, and a RAM 540 through a bus 550.

  The ROM 530 stores in advance a display change program that exhibits the same function as in the above-described embodiment, that is, a character recognition program 531, a character determination program 532, and a character change program 533 as shown in FIG.

  The CPU 520 reads out these programs 531 to 533 from the ROM 530 and executes them, so that the programs 531 to 533 function as a character recognition process 521, a character determination process 522, and a character change process 523, respectively. Thus, the CPU 520 corresponds to the display data processing unit 172 shown in FIG.

  The HDD 510 stores various data used by the processes 521 to 523. The CPU 520 reads various data stored in the HDD 510 and stores it in the RAM 540, and the processes 521 to 523 execute various processes such as a character change process using the various data stored in the RAM 540.

  As described above, according to the information processing apparatus 1 according to the present embodiment, the character in the image area is recognized and the size of the character is determined. If the character size is smaller than the predetermined size, We decided to change the size. Thereby, the visibility of the characters on the screen can be improved by enlarging only the characters smaller than the predetermined size, and the information processing apparatus 1 can be easily handled even for an elderly person or a visually handicapped person. Can do.

  Furthermore, since the information processing apparatus 1 changes not only the character size but also the character thickness, font, and color based on the setting information management table 142 and the color conversion rule management table 143, the information processing device 1 is displayed on the display unit 10. Character visibility can be further improved.

  In addition, the information processing apparatus 1 performs layout adjustment on the display data after the character size is changed by the character changing unit, so that the layout of the image after changing the character size, thickness, etc. is corrupted. Visibility can be prevented.

  As described above, some of the embodiments of the present invention have been described in detail with reference to the drawings. The present invention can be implemented in other forms that have been modified or improved.

  For example, the background color recognition unit 104 may recognize the background color for each predetermined character string instead of recognizing the background color for each character recognized by the character recognition unit 101. The background color recognition unit 104 may recognize a color obtained by averaging the RGB values at each point in the background area as the background color of the image area. Thereby, processing can be simplified.
