Description

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

  Conventionally, fonts such as fixed pitch fonts and proportional fonts are used in information processing apparatuses. The fixed pitch font is also called a monospaced font, and is a font that displays each character with a uniform width regardless of the shape of the character. A half-width character is half as wide as a full-width character. On the other hand, proportional fonts are also called variable width fonts, and are fonts having different character widths for each character.

  Since the same-size font has the same character spacing, it is used for ASCII art or the like that consists only of a terminal emulator display screen or text. Thereby, even if it displays with what kind of terminal, it can display without breaking.

  On the other hand, all the character widths in the same font are displayed equally, but when character strings are formed using a mixture of different equal-size fonts, the character widths do not appear to be uniform from the whole character string. Patent Document 1 has been proposed as a technique that makes it difficult to look good and to deteriorate the appearance when different fonts are mixed.

JP-A-8-335069

  In Patent Document 1, each character of a character string to be displayed is selected from proportional character display and equal character display, and arranged according to the selected display content.

  However, there exists an information processing apparatus that cannot display a normal font and can display only a proportional font, such as a tablet terminal. In such an information processing apparatus, the same size font is originally used. Therefore, it is impossible to select the same size character display as proposed in Patent Document 1.

  In order to display the same size font on the tablet terminal, it is sufficient to use a style sheet (CSS). In this case, however, it takes time to specify the style sheet in advance.

  In view of such a problem, an object of the present invention is to provide a mechanism capable of displaying characters so as to appear at regular intervals even in a situation where a normal font cannot be used.

  An information processing apparatus capable of displaying characters, a virtual cell setting means for setting a virtual cell that is an area for displaying the character, and a center of the virtual cell when a character string to be displayed is a single-byte character When the character string to be displayed is a full-width character, the display character placement portion for placing the full-width character at the center of the two virtual cells and the display character placement portion are arranged. And a display control unit that displays the characters so as to fit in the virtual cell.

  According to the present invention, even in a situation where a normal font cannot be used, characters can be displayed so as to appear at regular intervals.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram illustrating an example of an information processing system including an information processing apparatus according to an embodiment of the present invention.

  The information processing system of the present invention is preferably configured by connecting a main frame 101 and a client terminal 102 via a LAN (network) 105.

  The mainframe 101 is a large computer system used for a company's core business system. Most parts including a power supply, CPU, and storage device are multiplexed, and improvement of processing performance and fault tolerance is achieved by parallel processing. It is also called “general-purpose machine”, “general-purpose computer”, “large-sized machine”, “large-sized computer”, “server apparatus”, and the like.

  A plurality of client terminals 102 are connected through the LAN 105, and a user uses data through the client terminal 102. Data processing and storage are generally performed by the mainframe 101, which is a centralized structure.

  The client terminal 102 displays the data received from the mainframe 101 on the screen as a terminal emulator screen. The present invention can be applied as an information processing apparatus in the present invention.

  In this system configuration, the data received from the mainframe 101 is described to be displayed on the client terminal 102. However, the content displayed on the client terminal 102 is limited to the content received from the mainframe 101. Instead, for example, data received from a WEB server (not shown) may be displayed, or the application provided in the client terminal 102 may be configured to operate only on the client device 102.

  When the client terminal 102 is a tablet terminal, only proportional fonts may be displayed, which is effective in such a case. In addition, by performing the processing of the present invention on an information processing apparatus set to display in proportional font, it is possible to display characters at regular intervals without changing the font to be displayed.

  FIG. 2 is a diagram illustrating an example of a hardware configuration of the information processing apparatus according to the present invention.

  As shown in FIG. 2, in the information processing apparatus (client terminal 102), a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, and a storage device 204 via a system bus 200. , An input controller 205, an audio input controller 206, a video controller 207, a memory controller 208, and a communication I / F controller 209 are connected.

  The CPU 201 comprehensively controls each device and controller connected to the system bus 200.

  The ROM 202 or the storage device 204 is a control program executed by the CPU 201 such as a basic input / output system (BIOS) or an operating system (OS), a computer-readable program for realizing this information processing method, and various necessary programs. Holds data (including data table).

  The RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for executing the processing from the ROM 202 or the storage device 204 to the RAM 203 and executing the loaded program.

  The input controller 205 controls input from an input device such as a keyboard / touch panel 210. The input device is not limited to this, and may be a touch panel capable of detecting a position touched by a plurality of fingers, such as a mouse or a multi-touch screen.

  Various instructions can be performed when the user presses (touches with a finger or the like) in accordance with an icon, a cursor, or a button displayed on the touch panel.

  This input device is used to input a destination for a communication destination that can be used by various communication devices.

  The voice input controller 206 controls input from the microphone 211. Voice input from the microphone 211 can be recognized.

  The video controller 207 controls display on an external output device such as the display 212. The display includes a display of a notebook computer integrated with the main body. The external output device is not limited to a display, and may be a projector, for example. Further, for devices that can be received by the touch operation described above, it is also possible to receive input from the keyboard / touch panel 210.

  The memory controller 208 controls access to the external memory 213. The external memory is connected via an adapter to an external storage device (hard disk), flexible disk (FD), or PCMCIA card slot that stores boot programs, various applications, font data, user files, editing files, and various data. A compact flash (registered trademark) memory or the like can be used.

  The communication I / F controller 209 is connected to and communicates with an external device via the network 214, and executes communication control processing in the network. For example, communication using TCP / IP, telephone lines such as ISDN, and communication using 3G lines of mobile phones are possible.

  The storage device 204 is a medium for permanently storing information, and the form is not limited to a storage device such as a hard disk. For example, a medium such as SSD (Solid State Drive) may be used.

  It can also be used as a temporary memory area during various processes performed by the communication terminal in the present embodiment.

  FIG. 3 is a diagram illustrating an example of a functional configuration of the information processing apparatus according to the present invention.

  The information processing apparatus 102 according to the present invention has a display 301 (or is connected so as to be capable of display control), and includes a data receiving unit 302, a display area setting unit 303, a display character arrangement unit 304, characters, The display control unit 306 includes a size control unit 305 and a display control unit 306, and the display control unit 306 performs display control on the display 301.

  The data receiving unit 302 receives data to be displayed from a host computer such as a main frame. The display area setting unit 303 sets an area in which characters to be displayed can be arranged on a screen that is a display area. For example, a virtual grid is created for the display area, which is used as the display area.

  The display character arrangement unit determines where the character to be displayed is arranged in the area set by the display area setting unit. If the character to be displayed is a half-width character, it is placed in the center of one square, and if it is a full-width character, two squares are used and placed in the middle of the two squares.

  The character size control unit 305 performs control so that the font size of full-width characters to be displayed is larger than the font size of half-width characters under a predetermined condition.

  FIG. 4 is a diagram showing an example of a display screen of the information processing apparatus according to the present invention.

  A tablet terminal 401 which is an information processing apparatus has a display screen 402. Normally, an emulator screen has a display area of 24 lines × 80 columns, and it is assumed that a normal font is used for displaying characters.

  However, operating systems (OS) such as iOS and Android used in tablet devices do not have the same-size font, or even if they do, the ratio of full-width to half-width does not become 1: 2. There is.

  Therefore, in the present invention, a virtual cell is created by dividing a line in the X direction of the display screen 402, which is an area on the emulator screen, into 24 parts, and dividing a digit in the Y direction into 80 parts. The character display area 403 is used. When displaying full-width characters, the display area 403 is displayed by using two squares.

  At this time, when half-width characters are displayed, centering display is performed on one square, and when full-width characters are displayed, centering display is performed on the center of two squares so that the characters appear to be equally spaced.

  The character size at this time is determined by the size (X px, Y px) of the display screen 402.

  A display example 411 is a diagram illustrating an example of the emulator screen 411 displayed on the screen 402. In this screen, data transmitted from the main frame 101 is displayed.

  In the display example 412, the character string “information” is displayed in single-byte characters. In the display example 413, the character string is displayed in four lines. In the “DATA SET password”, “DATA SET” is displayed in half-width characters, and “password” is displayed in full-width characters. In addition, the other three character strings “initial macro”, “profile name”, and “format name” are displayed in double-byte characters. A display example when these character strings are displayed in a proportional font or when displayed using the present invention will be described with reference to FIG.

  FIG. 5 is a diagram illustrating an example of a character string displayed on the information processing apparatus according to the present invention.

  Display examples 412 and 413 correspond to display examples 412 and 413 shown in FIG.

  A display example 412 is an enlarged display of the “information” that is a single-byte character displayed on the emulator screen.

  A display example 501 represents an example in which a font (for example, a proportional font) designated by the system or the user is displayed as it is. As shown in the figure, the row (Y coordinate) of the character display position is constant, but the column (X coordinate) differs depending on the previous character, so the display position is not aligned, and other display examples In comparison, the display positions may not be aligned and the interval may be narrowed.

  In the display example 502, one character is arranged for each virtual square. In this case, since the display positions of the characters are determined at equal intervals as indicated by arrows 504, the width of one line is unified to the same size. Single-byte characters occupy the area of one square. (In the case of double-byte characters, as will be described in display example 413, it occupies the area of two squares.)

  However, in the display example 502, since the width differs depending on the character, the character spacing may be wide or narrow (for example, the character spacing between the first character “i” and the second character “n” is wide, and six characters The character spacing between the “m” of the eye and the “a” of the seventh character is displayed narrowly.) There may be a problem in readability because characters do not appear to be displayed at regular intervals.

  Therefore, in the present invention, as shown in a display example 503, centering display is performed so that characters are arranged in the center of one square. As a result, the display positions of the rows are aligned in addition to the columns, so that the character intervals can be displayed so as to appear at regular intervals.

  The display example 413 is an enlarged display of the “initial set” that is a full-width character and the “DATA SET” that is a half-width character displayed on the emulator screen.

  The first column of display example 511 is an example in which “initial mac”, which is a full-width character, is arranged at the center of two squares. (The same applies to “Profile” and “Format Name”.)

  However, even if such a display is performed, even if it is originally a full-width character having a display width double that of a half-width character, the character interval between the “initial” and “initial” of the “initial mac” is too wide. For example, the half-width character “D” and the full-width character “Hatsu” may appear to be the same size.

  Therefore, in the present invention, as shown in the display example 512, full-width characters are displayed in a larger size (larger font size) than half-width characters.

  In the display example 511, the font size of the half-width character and the full-width character are the same, whereas in the display example 512, the full-width character is displayed in a larger font size than the half-width character. For example, if the font size is set to 10 points in the font settings, half-width characters can be displayed as 10 points and full-width characters can be enlarged and displayed at 12 points.

  As a result, the character spacing between the full-width characters of the character is increased, and the character can be displayed with improved readability.

  FIG. 6 is a flowchart showing an example of the overall flow of the information processing apparatus according to the present invention.

  This is processing performed when the display control unit of the client terminal 102 displays the character string received from the host computer on the emulator screen.

  In step S601, a virtual cell is set (virtual cell setting means). Although details will be described later with reference to FIG. 7, the display area of the character to be displayed is set.

  In step S602, the character data to be displayed is analyzed. In step S603, if the result of the analysis is half-width, the process proceeds to step S604, and if it is full-width, the process proceeds to step S605.

  If the character is a single-byte character, centering display is performed so that the display area is centered with respect to one square in step S604. For example, it is displayed as shown in a display example 503 in FIG.

  If it is a double-byte character, centering display is performed so that the display area is centered with respect to two squares in step S605, and the process proceeds to step S606 to perform character enlargement processing. Although details will be described later with reference to FIG. 8, this is a process for controlling the size of the displayed character. For example, it is a process of enlarging a predetermined size for a half-width character.

  It is also possible to determine whether to perform character enlargement processing according to the font type. For example, for a font that does not appear wide even if centering display is performed using two squares (for example, proportional font A), the process of step S606 is not performed, and a font that looks wide (for example, proportional font B) is displayed. On the other hand, the process of step S606 may be performed.

  If only the processing in step S605 for performing centering display is performed, for example, a display example 511 in FIG. 5 is displayed. If character enlargement is performed in S606, the display is performed as in display example 512.

  Note that the processing in step S606 is not necessarily performed, and can be switched ON / OFF by setting the emulator.

FIG. 7 is a flowchart showing an example of a virtual cell setting process of the information processing apparatus according to the present invention.
This corresponds to step S601 in FIG. 6 and virtual cell setting processing.

  In step S701, the size of the screen area is acquired. Taking 402 in FIG. 4 as an example, the sizes of “X px (pixel)” and “Y px” are acquired.

  In step S702, the acquired size is divided into vertical and horizontal 24 × 80, and the size of one virtual square (403 in FIG. 4) is calculated. The division is not limited to 24 × 80 and can be arbitrarily specified.

  In step S703, the font size is determined so that a half-width character having a maximum width (for example, “w”) can be accommodated with respect to the virtual cell, and the process ends. The reference character string need not be limited to “w”, and may be a character having the maximum horizontal width in the font to be used. The concept of determining the font size will be described later with reference to FIG.

FIG. 8 is a flowchart showing an example of display character enlargement processing of the information processing apparatus according to the present invention.
This corresponds to step S606 in FIG.

  In step S801, the ratio between the square height and the font height is obtained. In step S802, the font size is multiplied by the obtained ratio to determine the display font size of the full-width character, and the process ends. Here, the enlargement ratio is calculated using the height ratio of the font size of full-width characters, but this is not the only method, and the font size of full-width characters corresponding to the font size of half-width characters is determined in advance. You may make it leave. For example, in the case of 10 half-width characters, the full-width characters may be set to 12 points. Further, the font size may be stored in association with the font type.

  FIG. 9 is a diagram showing an example of a conceptual diagram for determining the font size of the information processing apparatus according to the present invention.

  In step S703, the font size is determined so that the character with the maximum horizontal width can be accommodated. First, X′904, which is the size that can be accommodated, is determined for the horizontal width X901.

In step 801, since the ratio between the cell height and the font height is obtained, the ratio between the height Y901 and the font height Y′902 is obtained. For example, when the ratio is 40%, double-byte characters are displayed with a font that is 1.4 times the current font.
FIG. 10 is a diagram showing an example of a font table in the present invention.

  6 is a table in which whether or not to perform the character enlargement process in step S606 of FIG. 6 and how to determine the size of the font to be enlarged when it is executed.

  The font name 1002 is a displayable font name of the information processing apparatus. Full-width enlargement 1003 is a setting for whether or not full-width characters are enlarged when they are displayed in the corresponding font, that is, whether or not the processing in step S606 in FIG. If “Yes” is set, S606 is processed.

  The enlargement method 1004 is set as a method for determining the font size when enlarging full-width characters. When “Calculate by ratio” is selected, the font size is determined by the method shown in FIG. 8. When it is “1.2 times the half-width character”, for example, when the half-width character is 10 points When a full-width character is 12 points and a half-width character is 20 points, the full-width character is displayed at 24 points.
