FIG. 1 is a configuration diagram of an information processing apparatus according to an embodiment of the present invention, FIG. 2 is a configuration diagram of a program executed by the CPU 1 shown in FIG. 1, and FIGS. FIG. 12 is a conceptual diagram showing a method of displaying a screen on a CRT 6 in the information processing apparatus. FIGS. 12 and 13 show display examples of a screen in the information processing apparatus of the present embodiment.
4 to 23 are flowcharts showing a display procedure by a program executed in the CPU 1. FIGS. 24 and 25 are conceptual diagrams showing a method of updating data on the VRAM 4 shown in FIG. 1, and FIGS. 26 and 27. Is an example of a display screen in a function of selecting a partial area from text information.

<Configuration of Information Processing Apparatus> FIG. 1 shows a configuration diagram of this information processing apparatus. The information processing apparatus includes a hard disk 3 for recording programs and data, a memory 2 for temporarily storing these programs and data, a CPU 1 for executing the programs stored in the memory 2,
A CRT 6 for displaying data output by the PU 1; a VRAM 4 for temporarily storing the data to be displayed; a CRT controller 5 for reading the data in the VRAM 4 and transferring the data to the CRT 6 for display; And a mouse 8 for operating the mouse.

FIG. 2 shows a configuration of a program executed by the CPU 1. The information processing apparatus according to the present embodiment has a CPU
1, an information processing program 10 as shown in FIG.
(So-called application program) and OS 11
And a function for displaying text information by executing a three-layer program called the device driver 12.

The information processing program 10 reads the information stored in the hard disk 3 or the memory 2 and displays the information on the CRT 6 as it is or by adding a change specified by the user as text information. This information processing program 1
Reference numeral 0 corresponds to a user interface unit such as a word processor, a text editor, e-mail viewing software, spreadsheet software, address book management software, database management software, and the like.

The OS 11 controls the information processing apparatus according to the present embodiment and provides an environment in which the information processing program 10 is executed.

The device driver 12 is a program for controlling hardware such as the CRT 6, the hard disk 3, the keyboard 7, and the mouse 8 in accordance with an instruction from the OS 11, and is provided corresponding to each hardware.

<Overview of Text Information Display> FIGS. 3 to 6
1 shows an outline of screen display on the CRT 6 provided in the information processing apparatus according to the present embodiment. The information processing program 10 executed by the CPU 1 reads out text data from the hard disk 3, creates display data shown in FIGS.
To be displayed. Here, the window 29 is one screen constituting a multi-window system included in the OS 11.

For example, when operating a text file using a text editor, the display source data 30 shown in FIG. 3 is transferred from the hard disk 3 to the memory 2 and a part thereof is displayed as a display screen display 31 before movement. Displayed on CRT6. When the user browses the entire contents of the display source data 30, the user presses a move key (arrow key) on the keyboard 7 or moves a scroll bar (not shown) on the window 29 displayed on the CRT 6 with the mouse 8. By operating, the display range is moved and the display source data 30 is sequentially displayed on the screen. This operation is called scrolling. The information processing program 10 provides a user with a function of scrolling text information using the keyboard 7 or the mouse 8 and the scroll bar of the window 29.

In a conventional information processing program, a format (character spacing and line spacing), a character font size and an image size, a display shrinkage (zoom) that can be specified by an application, a screen resolution, and the like are used. Documents, text, images, etc. are displayed. Such a conventional display state is called a normal display state.

In such an information processing apparatus, when scrolling a large amount of text information, the faster the scrolling movement, the more convenient. However, when the scrolling speed is high, it is difficult to grasp the contents of the text information during the scrolling in the normal display state.

In order to solve such conflicting problems of high-speed scrolling and content comprehension, the information processing apparatus of the present embodiment displays screens as shown in FIGS.

In FIG. 3, the arrow 35 indicates the direction of scrolling. When the user continuously performs a scroll operation with the keyboard 7 or the mouse 8 in the direction of the arrow 35 in FIG. 3, the device driver 12 corresponding to the keyboard 7

The information processing program 10 detects a user operation through the OS 11 and the OS 11 and changes the display range of the display source data 30 with an arrow
Move in the direction of 5. If the move operation is continuous,
Text information (a part of the display source data 30) on the screen is continuously scrolled.

At this time, the information processing program 10 displays the moving display screens 32 to 34 according to a predetermined setting mode. In the present embodiment, a change operation, for example, a change operation for changing a displayed range of information to be displayed is referred to as a move operation.

On the moving display screen 32, characters on the screen (on the window displaying the text information) are uniformly reduced at a predetermined magnification. As a result, before moving, 1111
The screen displaying the range of 1 to 33333 is expanded to 11111 to 66666, and is scrolled in the direction of arrow 45 in this state.

On the moving display screen 33, characters are reduced and displayed at a predetermined magnification except for the line indicated by 66666. On the other hand, the line at the leading end in the moving direction of the screen indicated by 66666 is displayed without being reduced. Such a line at the leading end in the screen moving direction is called a focus line, and is a line that the user pays particular attention to during scrolling. In the present information processing program 10, the user can specify the number of rows (N rows) not to be reduced including the focus row. In the display screen 33 of FIG. 3, N = 1 is specified.
A predetermined number of lines including a focus line that does not reduce such characters correspond to one or more specific lines.

On the moving display screen 34, the magnification is changed stepwise in the moving direction of the display range indicated by the arrow 35 to display the characters. In the present embodiment, the display processing for changing the magnification stepwise includes a mode for changing the magnification linearly and a mode for changing the magnification in a curve.

FIG. 4 shows a case where the moving direction is an upward direction as indicated by an arrow 45. Also in this case, similarly to the above-described downward scroll, the display screen 41 before the movement is displayed as the display screens 42 to 44 during the movement. On the moving display screen 42, the characters on the screen are uniformly reduced at a predetermined magnification, and on the moving display screen 43, predetermined N lines including the focus line (the number of lines N can be specified by the user separately. 4
The display screen 43 is reduced in rows except for N = 1),
On the moving display screen 44, the magnification is changed stepwise in the moving direction of the display range.

FIG. 5 shows a case where the moving direction is rightward as indicated by an arrow 55. Also in this case, similarly to the above, the display screen 51 before the movement is replaced with the display screens 52 to 52 during the movement.
It is displayed as 54. On the moving display screen 52,
The characters on the screen are uniformly reduced at a predetermined magnification, and on the moving display screen 53, a predetermined N digits including the focus digit (the end of the screen moving direction indicated by PPPPP) (the number of digits N is separately set by the user). Can be specified, when the display screen 53 in FIG. 5 is N = 1)
Digits other than are reduced, and on the moving display screen 54, the magnification is changed stepwise in the moving direction of the display range.

FIG. 6 shows a case where the scroll direction is the left direction as indicated by an arrow 65. Also in this case, similarly to the above, the display screen 61 before the movement is displayed on the display screen 6 during the movement.
It is displayed as 2-64. On the moving display screen 62, the characters on the scrolling screen are uniformly reduced at a predetermined magnification, and on the moving display screen 63, the characters including the focus digit (the end in the screen moving direction indicated by the MMMMM) are displayed. (The number of digits N can be specified by the user separately; the display screen 63 in FIG. 6 is N = 1), and the display screen 64 being moved is stepwise in the moving direction of the display range. Is changed.

FIG. 12 shows an example in which text information is actually scrolled in an information processing apparatus for displaying as described above, and characters on the screen are uniformly reduced at a predetermined magnification. When the image displayed before the movement is displayed as in the screen 85 and scrolled downward, the image is reduced as in the screen 86 and the display range is expanded. In this state, scrolling proceeds, and after scrolling, the character is displayed again in the normal character size as on the screen 87.

FIG. 13 shows a function of selecting a partial area in text information, which is another function of the information processing apparatus according to the present embodiment. This corresponds to, for example, an operation before cut-and-paste. In the operation of selecting the partial area, if the range to be selected exceeds one screen, the information processing apparatus of the present embodiment reduces the size of the character until the range fits on one screen, and It is displayed (screen 89 shown in FIG. 13).

In FIG. 13, the selected partial area is rectangular. On the other hand, as shown in FIG. 26, in the case where the partial area 97 has a shape other than a rectangle that starts in the middle of a row and ends in the middle of the row, a rectangular display area 98 including the selected area is similarly formed. What is necessary is just to reduce the size of a character so that it may fit on one screen.

<Operation Example> The operation of the information processing apparatus according to the present embodiment will be described with reference to FIGS.

14 to 16, FIG. 18, FIG. 20, FIG.
23 to 23 are flowcharts showing the processing of the information processing program 10 executed by the CPU 1.

FIG. 14 is a flowchart showing an outline of the entire operation of the information processing program 10 performed in response to an event (hereinafter referred to as a key event) generated by a key operation or a mouse operation by the user.

First, the information processing program 10 acquires a key event (Step 110, hereinafter abbreviated as S110). The key event acquisition is a process of detecting the type of a key event to occur and the number of occurrences.

FIG. 15 shows details of the key event acquisition process. First, the information processing program 10 initializes a variable KeyCount for measuring the number of key events to 1 (S
111). Wait until the next key event is acquired (S1
12). When a key event occurs, it is determined whether KeyCount is 10 or more (S113). If KeyCount is less than 10, whether or not the display range is being moved (for example, whether or not a key is being pressed, or whether or not a scroll bar is being operated)
Is determined (S114), and when the display range is being moved,
KeyCount is counted up (S115). afterwards,
The information processing program 10 returns the control to S112.

If the display range is not being moved, the type of key event and KeyCount are reported to the upper module, and the flow advances to S130.

On the other hand, when KeyCount is 10 or more (S1
13), end the key event acquisition processing, report the type of key event and KeyCount to the upper module, and execute S13.
Go to 0.

After the key event processing, the information processing program 10 determines whether or not a shift of the screen display range (hereinafter referred to as a screen transition) occurs due to the key event (S130). When a screen transition occurs, S140 to S
The processing associated with the display during the screen transition of S300 to S700 classified by 170 is executed.

When the event is the end of the screen transition, the character size, the line spacing, and the digit space before the screen transition are returned to display the text information after the end of the transition (S300). Thereafter, the information processing program 10 returns the control to S110.

If the event is not the end of the screen transition, that is, the movement of the screen display range, the information processing program 10 executes the processing according to a preset processing mode.
One of the processes from 400 to S700 is executed. This processing mode is recorded in the memory 2 as a flag indicating the processing mode.

<Character size change display at the same magnification within the screen> When the set processing mode is display at the same magnification within the screen, the character size and line spacing of the text information scrolled and displayed on the screen with the screen transition Then, the display shown in the moving display screen 32 of FIG. 3 is performed with the inter-digit space reduced at a predetermined fixed magnification (S400). The details of this processing are shown in FIG.
6 is shown in the flowchart.

First, the information processing program 10 determines whether the screen transition, that is, the change of the display content accompanying the scrolling of the screen is the first event or the second or subsequent event of successive screen transitions. Judgment (S40
1).

If this is the first event of the screen transition,
The text information on the currently displayed screen is changed (reduced) at a fixed magnification and displayed (S402). As a result, a blank is generated on the screen, and the number of lines (or the number of digits, the same applies hereinafter) of the text information to be displayed in the blank is calculated (S40).
3). In this case, the number of lines to fill the blanks is calculated by the character size after reduction at a fixed magnification.

Next, the text information of the number of lines corresponding to the blank is obtained from the moving direction of the screen movement (S404). Next, the character size, line spacing, and digit spacing of the acquired text information are similarly reduced at a predetermined fixed magnification (S406).

Based on the above, the VRAM 4 is updated with the reduced display data (S407). The data on the VRAM 4 is displayed on the CRT 6 (S408). VRA
The updating of the M4 and the display on the CRT 6 are executed by the device driver 12 via the OS 11 in accordance with an instruction from the information processing program 10.

FIG. 24 shows a process of expanding the text information of the display range in the VRAM 4. The device driver 12
Text information corresponding to 11111 to 55555 is received from the information processing program 10, and display data is developed in a bitmap format at coordinate positions ((X0, Y0) to (X3, Y3)) of the VRAM 4 corresponding to the display positions of the CRT 6. .

On the other hand, if it is determined in the processing of S401 that the screen transition is the second or later event, the screen transition is ongoing and the continuation processing is executed (S40).
5). That is, as the display range is moved, the data of the row (or digit) at the position opposite to the moving direction in the currently displayed portion is deleted from the display range. Next, text information located in the moving direction is obtained.

The text information of the display range updated in this way is changed in the same manner as described above, and the character size, line spacing, and digit spacing are changed (S406), the VRAM 4 is updated (S407),
The screen output (S408) is executed, and the control returns to the next key event acquisition (S120, S112).

By such processing, the display screen 3 shown in FIG.
2. As in the display screen 42 of FIG. 4, the display screen 52 of FIG. 5, or the display screen 62 of FIG. 6, the display range is enlarged by reducing the character size, line spacing, and digit spacing, and the scrolling text is displayed. Is done.

<Focus Line (Focus Digit) Emphasis Display> When the set processing mode is the focus line emphasis display, the character size, line spacing, and digit spacing of lines excluding a predetermined number (N lines) including the focus line Is reduced at a predetermined fixed magnification, and the display shown on the moving display screen 33 in FIG. 3 or the moving display screen 43 in FIG. 4 is displayed (S500). These are cases where the moving direction of the display range is up and down, but also when the moving direction is right and left, similarly, the character size, line spacing, and space between digits except for a predetermined number of digits (N digits) including the focus digit are changed. The image is reduced at a predetermined fixed magnification and the display shown on the moving display screen 53 in FIG. 5 or the moving display screen 63 in FIG. 6 is displayed.

The number of rows (or digits) N not to be reduced is specified in advance by the user. The moving display screen 33 and the like in FIG. 3 show the case where N = 1. Thereby, the vicinity of the focus line is displayed in an emphasized manner. The details of this processing are shown in FIG.
8 is shown in the flowchart of FIG.

In FIG. 18, similarly to FIG. 16,
The information processing program 10 determines whether the screen transition, that is, the change in the display content accompanying the scrolling of the screen is the first event or the second or subsequent event of the continuous screen transition (S501). .

If this is the first event of the screen transition,
The text information on the currently displayed screen is changed (reduced) at a fixed magnification and displayed (S502). As a result, a blank space is generated on the screen, so that the number of lines (or the number of digits) of the text information to be displayed in that portion is calculated (S503). In this case, unlike the case of the same magnification in the screen of FIG. 16, among the lines (or digits) to fill in the blanks, a predetermined number N of rows (or digits N) preset by the user. Is calculated with a normal character size that does not reduce.

Next, the text information of the number of lines corresponding to the blank is obtained from the moving direction of the screen movement (S504). Next, the first N lines (the first N digits) of the acquired text information in the screen transition direction are displayed with normal characters that do not reduce the character size, line spacing, and digit spacing. Display data is created using characters reduced from (the other digits after the N digits) at a predetermined magnification (S506). As described above, the VRAM 4 is updated with the created display data (S
507). The data on the VRAM 4 is displayed on the CRT 6 (S508).

On the other hand, if it is determined in S501 that the screen transition is the second or later event, the screen transition is continuing and the continuation processing is executed (S505). That is, as the display range is moved, the data of the line (or digit) at the last position opposite to the moving direction in the currently displayed portion is deleted from the display range. Next, text information located in the moving direction is obtained.

In the same manner as described above, the text information of the display range updated as described above is compared with the first N rows (the first N
Digit) is displayed in a normal character font without reduction.
The display data is created by reducing the line and subsequent lines (after the N digits) at a predetermined magnification (S506). Furthermore, the VRAM 4 is updated (S
507), screen output (S508) is executed, and control returns to the next key event acquisition (S120, S112).
Return to

By such processing, the display screen 3 shown in FIG.
3, the text information being scrolled is displayed in a normal character size in which only predetermined N lines including the focus line are not reduced as shown in the display screen 43 of FIG. 4 (N in FIGS. 3 and 4).
= 1). The display screen 53 of FIG. 5 or FIG.
The same applies to the case where the moving direction is the horizontal direction as in the display screen 63 of FIG.

<In-Screen Linear Reduced Display, In-Curve Curved Reduced Display Processing> When the set processing mode is the in-screen linear reduced display, the moving display screen 34 in FIG. 3 and the moving screen in FIG. As shown in the screen 54, the character size, line spacing, and column spacing are reduced and displayed in units of lines (or units) in the direction opposite to the scroll direction. The details of this processing are shown in FIG.
Is shown in the flowchart of FIG.

The process of FIG. 20 is the same as the above-described process of FIG. 16, but the process of S602 is different from the process of S402 of FIG.
Also, the processing of S605 is different from S405 of FIG. That is, in the processing of FIG. 16, the character size, line spacing, and column spacing are the same in the screen, but in the processing of FIG. 20, the characters are displayed in a reduced size in the direction opposite to the moving direction.

When the set processing mode is curvilinearly reduced display in the screen, text information is displayed in a curvilinear manner with respect to the moving direction, with the character size, line spacing, and digit spacing reduced.
The details of this process are shown in FIG.

First, the information processing program 10 acquires text information of a line (and a digit, the same applies hereinafter) to be added to the display range from the scroll direction (S701).

The position of the first line among the added lines is set as the center of the normal distribution, and the character size, line spacing, and digit space without reduction are set (S702). Further, for lines located on the screen in the direction opposite to the scroll after the first line, display data is created by reducing the character size, line spacing, and column spacing according to the normal distribution curve (S703). In this case, the spread of the normal distribution is stored in the memory 2 as a user-specified parameter.
Is determined by the number of rows corresponding to the standard deviation held in the row.

The VRAM 4 is updated based on the above display data (S704), and is displayed on the CRT 6 (S70).
5).

<Text Information Selection Operation> If it is determined in step S130 in the flowchart of FIG. 14 that the user's operation is not a movement of the screen display range (not a screen transition), then the operation is a text information selection operation. It is determined whether or not there is (S131). If the text information is not selected, the information processing apparatus of the present embodiment maintains the display area of the screen as it is (S132). Thereafter, the information processing program 10 returns the control to S110.

On the other hand, in the case of a text information selection operation, the character size and the like are reduced according to the size of the range (S800). Details of this processing are shown in the flowchart of FIG.

First, the information processing program 10 determines whether or not the selection operation of the text information has been completed (S80).
1). When the selection operation is completed, the character size and the like are returned to the normal size (S804). Then, next, the information processing program 10 generates display data from the text information selected using the characters of this size, and updates the VRAM 4 (S805). Further, the data of the VRAM 4 is output to the screen (S806).

On the other hand, if the processing has not been completed, the information processing program 10 acquires the number of selected lines (S802). Next, a reduction ratio for displaying the text information of the number of lines on the screen is calculated (S803). Next, the information processing program 10 generates display data from the selected text information using the character having the size determined from the magnification, and updates the VRAM 4 (S805). Further VRA
The data of M4 is output to the screen (S806).

<Effects of Embodiment> As described above,
According to the information processing apparatus of the present embodiment, at the time of screen transition such as scrolling, the character size is reduced and text information in a wider range than usual is displayed on the screen, so that it is easy to grasp the contents of the text information during scrolling. become. In that case, a predetermined number N of lines including the focus line or a predetermined number N of digits including the focus digit are displayed in characters of a normal character size, and the other lines and digits are reduced at a predetermined magnification. By displaying characters with the changed character size, it is possible to emphasize and display a newly displayed line (or column) that is most interesting to the user during scrolling.

Further, by displaying the size of the character as a character linearly reduced in the direction opposite to the scrolling direction, the size of the character is reduced stepwise from the focus line or the focus digit that the user is interested in. Rapid reduction can be prevented. Furthermore, by reducing the characters at a curved rate of change like a normal distribution, it is possible to emphasize and display the vicinity of the focus line or the focus digit with a natural change.

Further, in the information processing apparatus according to the present embodiment, when the selection range when text information is selected exceeds one screen, the character size is reduced to a size that fits on one screen and displayed. At the time of AND paste, it is easy to grasp the contents of the selection range, confirm the selection range, and the like.

<Modification> In the above embodiment, the magnification for reducing the character size does not depend on the key operation.
It was a predetermined fixed value. The character size, line spacing, digit spacing, and the like may be set based on key operation, scrolling speed of the mouse 8, or moving speed of the screen. For example, when detecting a user operation such as continuously pressing a key (arrow key) for designating screen movement, the longer the key is continuously pressed, the smaller the character reduction ratio may be. Also, the faster the scroll operation of the mouse 8 is, the smaller the character reduction ratio may be. this is,
When reducing at the same magnification within the screen, such as the display screens 32, 33 and 34 shown in FIG. 3, when reducing a line other than a predetermined line including the focus line, or gradually (linearly or curvilinearly) within the screen In any case, it can be applied.

FIG. 17 is a diagram showing a process of continuously pressing the keys (CPU) in the character size changing process at the same magnification within the screen.
1 illustrates an example of a process of changing the character size in accordance with the number of key events detected by (1). That is, the information processing program 10 stores a predetermined magnification in the memory 2 in advance for each variable corresponding to the number of key events as the magnification of the character size, and executes S422 or S426.
In the processing of (1), the character size is changed using the magnification stored in the variable corresponding to the number of key events at the time of operation.

FIG. 19 shows a case where, in the focus row (and focus digit) highlighting, rows other than the predetermined number N including the focus row (and digits other than the predetermined number N including the focus digit) are reduced. Key press time (CPU
This shows an example of processing for changing the character size in accordance with the number of key events detected in step (1). That is,
The information processing program 10 stores a predetermined magnification in the memory 2 for each variable corresponding to the number of key events as a magnification of the character size, and stores a variable corresponding to the number of key events at the time of operation in the processing of S522 or S525. Change the font size using the magnification stored in.

FIG. 21 shows a process for changing the character size in accordance with the time for continuously pressing the keys (the number of key events detected by the CPU 1) when the character size is linearly reduced and displayed on the screen. This is an example. That is, the information processing program 10 stores a predetermined magnification in the memory 2 in advance for each variable according to the number of key events as the magnification of the character size, and in the processing of S622 or S625, The character size is changed using the stored magnification.

In addition to the method (table lookup method) in which the magnification is stored in a variable that differs for each key event as described above (table lookup method), a unique calculation is performed from the number of key events based on a specific calculation formula (function). A method of calculating the magnification may be used.

In this embodiment, as shown in the moving display screen of FIGS. 3 to 6, character size change display at the same magnification in the screen, focus line (focus digit) highlight display, linear reduction in the screen The display and the in-screen curvilinear reduction display processing have been described. However, the present invention is not limited to these displays. For example, in order to easily grasp the contents of text information during scrolling, FIGS.
May be displayed.

In FIG. 7, three lines including the focus line are displayed as characters of a normal character size while scrolling downward, and the other lines are displayed in a reduced size. The same display is also made when the screen is moved in the horizontal direction.

In the present embodiment, when the focus line (the focus digit) is emphasized, a predetermined number of lines (the predetermined number of digits) including the focus line (the focus digit) is displayed in characters of a normal character size. As long as the function of emphasis is achieved, these may be displayed in characters larger than the normal character size, or may be displayed in characters smaller than the normal character size.

In FIG. 8, when scrolling up and down, characters near the right side of the screen (five digits from the right in FIG. 8) are displayed in normal size characters, and characters near the left side of the screen are at a predetermined magnification. Is displayed with the reduced character size and character spacing. Regarding which digit is displayed in a normal size and which digit is reduced, the number of digits and the digit position can be designated by the environment setting function of the information processing program 10 and these are stored in the memory 2 as parameters. I just need.

Thus, for example, it is easy to grasp the contents during scrolling in the display of a spreadsheet or a relational database in which important information exists near the right side of the screen. When scrolling in the horizontal direction, the same display can be achieved by displaying a specific line in a normal character size and displaying the other lines in a reduced size.

In FIG. 9, when scrolling in the vertical direction, the upper and lower portions of the screen are displayed in a normal character size, and lines near the center of the screen are displayed in a reduced character size at a predetermined magnification. When scrolling in the horizontal direction, the left and right portions of the screen are displayed in a normal character size, and digits near the center of the screen are displayed in a character size reduced by a predetermined magnification. This makes it easy to associate display contents in the vertical direction or the horizontal direction of the screen.

In FIG. 10, when scrolling up and down, lines near the center of the screen are displayed in a normal character size, and other lines are displayed in a reduced character size at a predetermined magnification. Similarly, when scrolling in the horizontal direction, digits near the center of the screen are displayed in a normal character size, and other digits are displayed in a character size reduced by a predetermined magnification.

In FIG. 11, when scrolling up and down, text information to be displayed is displayed as characters reduced at a predetermined magnification, and a part of the text information is enlarged and displayed in the right margin of the screen. For this purpose, the display data in the form of reduced characters on the left side of the screen and the display data in which a part of the right side of the screen is enlarged are transferred from the information processing program 10 to the device driver 12 via the OS 11 and are stored in the VRAM 4 in the format shown in FIG. What is necessary is just to generate a bitmap. As a result, while the text information is displayed in a wide range on the left side of the screen, a part of the text information is displayed in the margin on the right side of the screen in enlarged characters, so that the outline of the wide area can be grasped and the detailed information can be checked at the same time. .

In FIG. 11, a reduced display and a partially enlarged display are displayed on one screen, but these may be displayed on separate screens (windows). In that case, O
It is sufficient that two windows are generated by the window system included in S11, and the reduced text information and the text information obtained by enlarging a part of the text information are displayed in each window from the information processing program 10.

In the present embodiment, when displaying a partial area selected from text information, the same applies to a case where a partial area has a shape other than a rectangle that starts in the middle of a line and ends in the middle of a line. Then, the size of the character is reduced so that the rectangular display area including the selected area fits on one screen (FIG. 26). In this case, instead of reducing the size of all the characters in the rectangular display area 98 including the selected area 97, only the characters in the selected partial area are reduced as shown in FIG. Except for the part 96 (the part that is less than one line each at the beginning and end of the rectangular display area)
May be displayed in a normal character size.

In the above embodiment, the description has been made using the window of the multi-window system as the screen of the display unit. However, the present invention is not limited to the multi-window system.

In the present embodiment, the display in reduced characters is performed by the OS 1 in accordance with an instruction from the information processing program 10.
1, the device driver 12 generates a bitmap in the VRAM 4 and performs the operation. However, the character reduction may be performed not by such a program but by reducing data once generated in the VRAM 4 as a bitmap by hardware. This concept is shown in FIG. In FIG. 25, the image data 93 generated in the VRAM 4 is reduced to １ ／ by the filter circuit (bitmap thinning is performed), and the text information in the screen moving direction is captured in the margin of the image 94 generated as a result. , Display data 95 is created.

In the above embodiment, the present invention has been described mainly on the case where text data is displayed. But,
Embodiments of the present invention are not limited to displaying text data. For example, only image information, and information in which text information and image information are mixed can be processed by the present invention.
When the image information is included in the processing target, the display size, the interval between the image information, and the interval between the text information and the image information (vertical direction, horizontal direction) may be controlled. Further, for example, the magnification (scaling) processing shown in FIGS. 3 to 11 may be applied to image data (bitmap data or vector data). This may be performed by a program on the CPU, or may be realized by hardware as shown in FIG.

The information processing program 10 of the present embodiment is recorded on a computer-readable recording medium, and is read by a computer.
The information processing apparatus according to the present embodiment can be realized by executing the processing together with S11 and the device driver 12. Here, the computer-readable recording medium refers to a recording medium in which information such as data and programs is accumulated by an electric, magnetic, or optical action and can be read by a computer. Examples of such a recording medium include a floppy (registered trademark) disk, a magneto-optical disk, a CD-ROM, a CD-R / W, an MO, a DVD, a DAT, an 8 mm tape, a memory card, and the like. Further, this program can be stored in the hard disk 3 or the memory 2 of the computer and distributed to other computers through a communication line. As a result, the computer to which the information processing program 10 has been distributed can function as the information processing apparatus of the present embodiment.
