[Structure] When the area to be displayed is selected so that the cursor indicating the current processing target is always located near the center of the screen 501, the screen 401 that must be displayed on the displayable screen 501 is not displayed. Instead, only a part may be displayed. If the part displayed on screen 501 is screen 4
If it protrudes from 01, a frame line is added to distinguish the protruding portion. At this time, in order to make the position of the image being operated on the original screen 401 easy to understand, the frame line is displayed with a scale.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device having a display as an output device such as a computer and a word processor.

[0002]

2. Description of the Related Art Recently, in computers and word processors, the amount of information to be displayed has increased along with the improvement in performance. Therefore, the size of the screen (actual screen) of the display equipped in those devices is the image to be displayed. It may not be possible to display all. Therefore, the image to be displayed is assumed to be a logical screen (logical screen), a part of it is displayed on the actual screen, and the display range can be set arbitrarily on the logical screen to display the entire logical screen. The method that was made possible has become common sense.

For example, in the case of a word processor, A4 paper 1
There is no problem as long as it can display one page on one screen, but the low-priced small display does not have that much display capacity. Figure 3
3A, if the size of the screen 201 in FIG. 3A is required to display one page of A4 size paper, the screen of FIG. Only the size of about 202 can be displayed.

Therefore, it is assumed that the screen 201 of FIG. 3A is a logical screen (logical screen) capable of displaying one page of A4 paper at one time, of which the actual screen (real screen) is displayed by the display capacity of the screen 202. ) Is displayed. In FIG. 3C, the actual screen 202 surrounded by the dotted frame is the part that is actually displayed with respect to the logical screen 201. By doing so, the portion displayed on the real screen on the logical screen can be processed by moving the current operation position (cursor).

The problem is the data processing of points on the logical screen that are not displayed on the real screen. For this reason, various methods have been put into practical use, but there are the following general methods.

When inputting text with a word processor,
Initially, the logical screen 201 and the actual screen 202 are shown in FIG.
As shown in (c), the cursor is at position 30 in the figure.
1 (hereinafter, 301 to 307 indicate positions on the logical screen). The cursor moves to the right by one character each time one character is input. When the cursor moves to the position 302, which is the right end of the real screen,
When a character is input, the real screen 202 is moved to the right by one character on the logical screen 201 as shown in FIG. 3D, and the cursor is also moved to the position 303 on the logical screen 201 by one character. After that 1
Each time a character is input, the real screen and the cursor move one character to the right of the logical screen, move to the end of the line, and move to the right side of the logical screen 201 and the real screen as shown in FIG. The right side of 202 overlaps. At this time, the cursor is at position 304.

This completes the input of the first line. The next one character moves to the second line. At that time, the state returns to the state of FIG. 3C, and the cursor moves to the position 305.

In this way, character input is repeated one after another,
When the cursor comes to the position 306 in the state of FIG. 3E, the next one character input causes the real screen 202 to move to the left end of the logical screen 201 as shown in FIG. Move to. At this time, the cursor is moved to the cursor arrangement 307.

As described above, by moving the real screen on the logical screen according to the movement of the cursor, it is possible to display an arbitrary position on the logical screen and perform data processing.

[0010]

However, when the display screen (actual screen) displays a part of the logical screen as in the above-mentioned proposal, the logical screen frame is displayed in the actual screen. In many cases, the display showing the frame has various expressions, but it merely shows the frame of the logical screen.

The present invention has been made in view of the above-mentioned conventional example, and it is possible to improve the work efficiency by displaying where the operator's attention and the peripheral image are located on the logical screen. The purpose is to provide a possible image display method.

[0012]

In order to achieve the above object, the image display method and apparatus of the present invention has the following constitution.

A determination step of determining a data area to be displayed from the image data area, a determination step of determining an area out of the image data area among the areas determined in the determination step, and a determination step of protruding in the determination step. And a display step of displaying a frame line with a scale for distinguishing the areas determined to exist.

Further, the determining means for determining the data area to be displayed from the image data area, the determining means for determining the area out of the image data area among the areas determined by the determining means, and the determining means. Display means for displaying a frame line with a scale for distinguishing the areas determined to be protruding.

[0015]

With the above configuration, a display image is constructed from the image data, and a portion outside the image data in the display image is
Divide by a graduated frame.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A word processor which is an embodiment of the present invention will be described below with reference to the drawings.

[Embodiment 1] <Structure> FIG. 1 is a diagram showing the structure of a word processor device of this embodiment. Reference numeral 102 denotes a main body of the apparatus, which stores data input from the keyboard 101 in the memory 105, processes the data, and stores the data again in the memory 105. The memory 105 stores not only data but also a program for processing the data or controlling the device. The CPU 104 controls the device and processes data according to a program in the memory 105, and controls input from the keyboard 101 and output to the display 103 / printer 106.

In the word processor device having such a configuration, a process when the display 103 cannot completely display one page of the document being edited will be described.

<Display Method> FIG. 2 shows the position of interest on the logical screen 201, that is, the cursor is the logical screen 2 in this case.
01 shows various cases where the actual screen 202 is always placed at the center of the screen no matter where it exists on 01. As can be seen, in all of FIGS. 2A to 2H, the cursor 203 is located at the center of the real screen 202. Further, when the outside of the frame of the logical screen is displayed on the real screen as shown in FIGS. 2A and 2B, the frame line is displayed or the color of the area outside the logical screen is changed. By distinguishing it, it is easy to see where the real screen is displayed on the logical screen.

For the purpose of detailed explanation, the word processor of the present embodiment is assumed to edit a document of 30 (characters) × 40 (lines) per page, and an arbitrary position on the logical screen corresponding to the page is set. It will be expressed in XY coordinates. That is, the position of each square 402 in FIG.
And the Y-axis 404 It is defined by [X, Y] such that At this time, the coordinates in the logical screen 401 are [X, Y; 1 ≦ X ≦ 30, 1 ≦ Y ≦ 4.
0] and the coordinates [X, Y; X <0 or X> 30, Y
<0 or Y> 40] represents outside the logical screen.

Similarly, as shown in FIG. 5, the actual screen (display screen) 501 of this word processor is set to a size of 20 × 20, and the character position 502 on the screen is set to the x-axis 503 and the y-axis 50.
It is represented by coordinates (x, y) according to 4. However, the outside of the screen is not considered on the actual screen. That is, x and y are always (x,
y; 1 ≦ x ≦ 20, 1 ≦ y ≦ 20).

In the above configuration, in the conventional example, the cursor position on the real screen changes in the state at that time.
Even if the cursor is fixed at a specific position on the logical screen, the cursor position on the real screen is not specified. Therefore, in order to display the cursor on the real screen, it is necessary to determine many states. Further, although the data and the frame are displayed on the real screen, it is not possible to know which position the displayed data occupies on the logical screen.

According to the present embodiment, the cursor position on the real screen 501 is set to the center portion 505 ((10, 10) in this example).
The information around the cursor can be always referred to, and at the same time, it is not necessary to determine many states as described above. Also, when the frame of the logical screen is displayed on the real screen, the coordinates on the logical screen can be written in the frame to know the positions occupied by the images during and near the operation in the logical screen. .

For example, when the cursor is located at the coordinate [15, 15] on the logical screen 401 as shown in FIG. 6, the cursor exists at the coordinate (10, 10) on the real screen 501 and is displayed on the real screen 501. The area of the logical screen 401 is [15- (10-1), 15- (10-1)] = [6,6] * () indicates the cursor position on the real screen and the upper left corner [1,1 ] [15+ (20-10), 15- (10-1)] = [25,6] * () indicates the difference between the cursor position on the real screen and the upper right corner [20,1] [15- (10-1), 15+ (20-10)] = [6,25] * () indicates the difference between the cursor position on the real screen and the lower left corner [1,20] [15+ (20 -10), 15 + (20-10)] = [25,25] * () indicates the cursor position on the actual screen and the lower right 4 points difference between [20, 20] was surrounded by (black portion in FIG.), I.e., [x, y; 6 ≦ x ≦ 25,6 ≦ y ≦ 25] is. The display screen at this time is as shown in FIG. In FIG. 9, reference numeral 901 denotes a display frame of the display 103, and the size of the real screen 501 is determined by this restriction.
A cursor 902 is located at the center of the real screen 501. This state corresponds to FIG. 2E, and the real screen 501
It does not change unless the part outside the logical screen is displayed inside.
At this time, the frame of the logical screen is not displayed, and thus the coordinates indicating the position on the logical screen are not displayed.

Next, when the cursor is at the upper left corner [1, 1] of the logical screen 401 as shown in FIG. 7 (state of FIG. 2A)
Will be explained. In this case as well, similar to the above example, the real screen 501
The cursor above exists at the coordinate (10, 10), and the area of the logical screen 401 displayed on the real screen 501 is [1- (10-1), 1- (10-1)] = [-8 , -8] [1+ (20-10), 1- (10-1)] = [11, -8] [1- (10-1), 1+ (20-10)] = [-8,11] [1+ (20-10), 1+ (20-10)] = [11,11] surrounded by four points (black portions in FIG. 7), that is, [x, y; −8 ≦ x ≦ 11, −8 ≦ y ≦ 11].

This is different from the above-mentioned case in that some of the areas of the logical screen 401 displayed by the real screen 501 have coordinate values of 0 or negative. The coordinates being 0 or negative indicate an outer portion (without character information) of the logical screen 401. Therefore, to display them on the real screen 501, the following is done.

(1) A frame line (corresponding to the edge of the sheet being edited) at the coordinates [0, Y; 0≤Y≤40] and the coordinates [X, 0; 0≤X≤30]. Is displayed. Since the cursor is located at the coordinate [1, 1], (9,
y; 9 ≦ y ≦ 20) and (x, 9; 9 ≦ x ≦ 20) are framed.

(2) Coordinates [X, Y; X <0 or Y <
[0] part is distinguished by a pattern such as diagonal lines or gradation difference to show that it is outside the logical screen, and in the case of color display, different color is used. On the real screen 501, the coordinates (x, y; x <9 or y <9) are outside the logical screen.

(3) The recorded character information (including blanks) is displayed on the inside of the logical screen.

The state of the display screen displayed as described above is as shown in FIG. The cursor 901 is located at the center of the real screen 501, and the outside of the logical screen is distinguished from the inside thereof as indicated by 903. A scale 111 indicating coordinates is attached to the frame line of the logical screen so that the position of each displayed character on the logical screen can be grasped.

Further, even when the cursor is at the lower left corner [1,40] of the logical screen (state of FIG. 2C), the cursor on the real screen is similarly positioned at [10,10]. Figure 8
, The area on the logical screen displayed on the real screen 501 is [1- (10-1), 40- (10-1)] = [-8, 31] [1+ (20-10), 40- (10-1)] = [11,31] [1- (10-1), 40 + (20-10)] = [-8,50] [1+ (20-10), 40 + (20-10)] = [11,50] surrounded by four points (black portions in the figure), that is, coordinates [X, Y; −8 ≦ X ≦ 11, 31 ≦ Y ≦ 50]. Then, the display is performed under the same conditions as the above definitions (1) to (3), but since the numerical values of (1) and (2) are different, the conditions are changed to (4) and (5).

(4) A frame line (corresponding to the edge of the sheet being edited) at the coordinates [0, Y; 1≤Y≤40] and the coordinates [X, 41; 1≤X≤30]. Is displayed. On the actual screen, coordinates (9, y; 1 ≦ y ≦ 10) and coordinates (x, 11; 9)
Draw a frame of the logical screen in ≦ x ≦ 20).

(5) Coordinates [X, Y; X <0 or Y> 4
The portion 1] is distinguished by a pattern such as a diagonal line to indicate that it is outside the logical screen, or a different color in the case of a gradation difference color display. The coordinates (x,
y; x <9 or y> 11) is outside the logical screen.

The display on the display 103 is as shown in FIG. Here again, the cursor 902 is located at the center of the real screen 501, the frame 111 of the logical screen is provided with the scale 111 indicating the coordinates, and the position of each displayed character and the cursor can be grasped.

Even when the cursor is at the upper right end or the lower right end as shown in FIGS. 2B and 2D, the numerical values of condition (1) and condition (2) are changed and displayed in the same manner. Logical screen coordinates [a,
The cursor position represented by b] is the coordinate (10, 1
0), which can be regarded as a parallel transformation. From this, when the coordinates [x, y] on the logical screen are converted into the coordinates on the real screen, it becomes (x + (10-a), y + (10-b)).

If these are put together, the conditions for displaying the logical screen on the real screen are as follows.

(6) Coordinates [X, Y; X = 0 or X = 3
1, 1 ≤ Y ≤ 40] and coordinates [X, Y; 1 ≤ X ≤ 30,
A frame line (corresponding to the edge of the sheet being edited) is displayed in the portion of Y = 0 or Y = 41]. That is, assuming that the cursor position is coordinates [a, b], (7) coordinates (x, y; x = 10-a or x = 41-a, 1 ≦ x ≦ on the actual screen.
20, 1 ≤ y ≤ 20) and coordinates (x, y; 1 ≤ x ≤ 2
0, y = 10-b or y = 51-b, 1 ≦ y ≦ 20)
Draw a border on.

(8) Coordinates [X, Y; X <0 or X> 3
1 or Y <0 or Y> 41] is distinguished by a pattern such as a slanting line or a gradation difference to show that it is outside the logical screen, and in the case of color display, a different color is used. That is, assuming that the cursor position is coordinates [a, b], (9) coordinates (x, y; x <10-a or x> 41-a or y <10-b or y> 51- on the real screen.
The part b) is outside the logical screen and is distinguished. As described above, the constraint (1 ≦ x ≦ 20, 1 ≦ y ≦ 20) is imposed.

(10) Coordinates [X, Y; 1≤X≤30,1
≤Y≤40], that is, the inside of the logical screen displays the character information (including blanks) recorded therein. This part is a part that does not meet any of the conditions (6) and (8). That is, assuming that the cursor position is coordinates [a, b], in the coordinate system of the actual screen, (11) coordinates (x, y; 11-a
The portion of ≦ x ≦ 40-a, 11-b ≦ y ≦ 50-b) is inside the logical screen. Of course, (1 ≦ x ≦ 20, 1 ≦
The condition is y ≦ 20).

As described above, the real screen is configured so that it is always located at the center of the real screen wherever the cursor is located on the logical screen. Further, the frame of the logical screen formed in the actual screen is provided with a scale for obtaining the coordinates of the logical screen at intervals of each character. The screen display routine for realizing the above display can be represented by the flowchart of FIG.

<Explanation of Flowchart> FIG. 12 is a flowchart showing a processing procedure when the cursor position is moved and the screen is displayed again by the input from the keyboard 101.

First, from the value of the input cursor position,
The area to be displayed on the logical screen is determined (S12).
1). The display area has the size of the actual screen centered on the cursor position. That is, the position of the cursor is coordinate [a, b]
Then, the coordinates [a-9, b-9] and the coordinates [a + 11, 11
b-9] and coordinates [a-9, b + 11] and coordinates [a + 1
1, b + 11] are the display targets.

Next, it is determined whether all the areas determined in step S121 are within the logical screen (S122). This may be determined by determining whether the area determined by the above four points is in the logical screen. That is, a-9 ≧ 1, a + 11 ≦
If the four conditions of 30, b-9 ≧ 1, b + 11 ≦ 40 are satisfied, it is within the screen.

When the logical screen is not completely filled, the frame of the logical screen is displayed. That is, first, a frame line drawn on the real screen is formed according to the item (7) described above. A scale is added to the formed frame line by the method of taking the coordinates shown in FIG. 4 (S123), and the scale is displayed (S124).

Next, the outside of the frame of the screen is filled with diagonal lines (S12).
5). This may also be drawn at the position as described in item (9).

Next, the document is displayed. This is the item (1
The coordinates as described in 1) are obtained and the data there is displayed (S126).

Finally, the cursor is moved to the coordinates (10,
10) and ends (S127) As described above, the display is re-displayed each time the cursor is moved. By doing so, it is possible to always display the data being operated on the screen and the data in the vicinity thereof, and to grasp the position of the image being operated on the logical screen, and to easily edit the document. Can be realized.

A coordinate input device such as a mouse may be attached to the word processor device of the embodiment other than that described in the embodiment, and various display devices such as CRT, LCD, and plasma can be considered. Further, what is placed at the center is not limited to the cursor position, and an area in which the operator is paying attention may be specified.

Further, if the inside and the outside of the logical screen are distinguished by a pattern or a color, the frame line may be omitted, and if there is the frame line, it is not particularly necessary to distinguish the outside.

As described above, by configuring the real screen so that the cursor is always located at the center of the real screen and displaying the position of the image to be operated with respect to the logical screen, information processing on the screen is performed. Makes it easier to refer to the information around the cursor, improving man-machine interface.

In particular, in the case of a graphics editor, the effect is great because the editing is often performed in consideration of the positional relationship with surrounding information and the distance from the frame of the logical screen.

Further, the cursor moving routine or the routine for constructing the real screen at this time always brings the cursor to the center of the real screen (that is, on the real screen in various cases as in the conventional example). Since there is no need to manage the cursor position of No.), it can be simplified as shown in FIG.

[0053]

[Other Examples]

Second Embodiment In the first embodiment, the area 903 outside the frame of the logical screen displayed on the real screen is wasted. This area becomes larger as the cursor approaches the edge of the logical screen. Therefore, in order to effectively use the real screen, if the upper, lower, left, or right edges of the logical screen are displayed on the real screen, the cursor is moved to the real screen without being positioned at the center of the real screen. Thus, FIG. 13 shows the case where the cursor is moved to the upper left corner of the logical screen, and FIG. 14 shows the case where the cursor is moved to the lower right corner. Even with such a display method, the position of the image being displayed on the logical screen can be grasped by giving the coordinate scale to the frame of the logical screen.

[Embodiment 3] Like Embodiment 2, Embodiment 1
In the following, we will explain the display method improved to eliminate the inefficiency of the actual screen usage.

In order not to waste the area 903 in FIGS. 10 and 11, even if the cursor is always at the center of the real screen, a portion substantially continuous to the portion where the cursor is present is displayed in the area 903. . In FIG. 15, the area 152 with the cursor is logically continuous from the area 151. The area 151 is data at the right end of the screen where the coordinate values of the logical screen 401 in the Y-axis direction are the same. Therefore, there is a shift of one line, but there is substantial continuity. Also in this case, a scale indicating coordinates is attached to the frame line of the logical screen. In FIG. 15, it can be clearly seen from the horizontal scale that the right end and the left end of the logical screen are connected and displayed.

FIG. 16 shows a logical screen display over one page. Areas 161 and 162, Areas 163 and 164
The respective relationships of 1 are the same as those described in FIG. In addition, areas 163 and 164 are data of the page immediately after the logical screen where the cursor is. If there are two consecutive pages, it is clear that the data has a logical connection. Also in this case, the frame line of the logical screen is provided with a scale indicating coordinates. This makes it easier to understand the relationship between the four sections on the actual screen and contributes to improving the work efficiency of the operator.

[Fourth Embodiment] Although the word processor has been described in the above-mentioned example, it is needless to say that not only the document processing but also various kinds of computer editors (including graphic editors) are also applicable. When a character is to be processed as in the previous embodiment, the coordinates of the screen are determined based on the character, but in the bitmap display, the coordinate is determined based on the bit.

Further, even if one page of the logical screen being edited can be displayed using a display having a large display capacity,
In the case of supporting the multi-window function which has been frequently used recently, when the number of displayed windows increases, the display capacity of one window inevitably decreases. Therefore, it can be similarly applied to the case where the display area of one window is considered as an actual screen.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

[0060]
