Abstract

PURPOSE:To obtain a displaying system in which the efficiency of work as seeing a display can be promoted by optimizing relevancy with other parts in accordance with the situation at the time of enlarging a part of a picture displayed on the display. CONSTITUTION:A mouse cursor 2 is displayed on the picture 1 of a window system like an X window, etc. When the mouse cursor 2 is moved to a part desired to enlarge and display, and the button of a mouse is pushed, the inside of a rectangular enlarged area 3 centering around the mouse cursor 2 is enlarged while the button is being pushed. Simultaneously with this, since an area 10 and the area 11 are reduced uniformly in a horizontal direction and a vertical direction respectively, information quantity to be displayed on the picture 1 is kept equal to that before the area 3 is enlarged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display system for display devices such as computers and word processors.

[0002]

2. Description of the Related Art When working with a computer or word processor, it is sometimes desired to pay attention to a part of a screen displayed on a display device. For example, in DTP (Desktop Publishing), when the layout of a document or a graphic and the correction of a sentence are performed at the same time, the entire view is displayed on one screen, and the area to be corrected can be enlarged as necessary. Is often easy to operate. Or, when the characters are displayed in full on the screen, when the information of a specific line is to be written on paper, the target line should be displayed so that it can be clearly distinguished from other lines. However, it is convenient because it is not easily confused with the next row. Conventionally, for such a purpose, a method as shown in FIGS. 14 to 17 has been considered (conventional example 1). This FIG. 14 and FIG.
5, FIG. 16, and FIG. 17 are disclosed in JP-A-04-14558, respectively.
No. 7 publication, “Picking method for image processing apparatus”. 14 and 15 are examples of a work screen by CAD. In FIG. 14, 51 is a cross-sectional view of a pillar, 52 is a reinforcing bar, 2 is a mouse cursor, and 50 is an enlarged display area.

The operation of the above-mentioned conventional example 1 will be described. When attempting to pick the reinforcing bar 52 in the column cross-sectional view 51 in FIG. 14, the operator moves the mouse cursor 2 to a position where the reinforcing bar 52 can be picked. At this time, the enlarged area 50 is
Following the movement of the mouse cursor 2, the portion including the reinforcing bar 52 is enlarged and displayed while the passage portion in the column cross-sectional view 51 is enlarged and displayed. FIG. 15 is a diagram when the rebar 52 is finally picked up, and the mouse cursor 2 is located at the center of the rebar 52 enlarged and displayed by the enlargement region 50. Also,
FIG. 14 shows a block configuration of an image processing apparatus in which the conventional example is implemented. As shown in FIG. 15, the storage device 55 stores a control program 56 for image processing including a program for figure picking, a management table 58 for storing setting values required for control, and the like. The control program 56 is read by the CPU 54 and executed.

Alternatively, a method of enhancing the luminance of a specific portion on the screen has been considered, as in Japanese Patent Laid-Open No. 58-173792, "Partial luminance enhancing device in electronic display device" (conventional example 2). ).

[0005]

Since the conventional display method is as described above, in the conventional example 1, only one enlarged area can be taken, and since a part is enlarged, the other area is not displayed. Part of it disappears. On the other hand, in Conventional Example 2, it may be better not to display the portion other than the portion to be emphasized, rather than changing the luminance to be emphasized and other luminance. That is, in Conventional Example 1, it may be inconvenient if the continuity between the enlarged area and the remaining area is lost. On the contrary, in the second conventional example, it may be easier to see only the information of the specific portion. As described above, conventionally, there has been a problem that the relationship between the part to be noticed and the remaining part is not necessarily optimal.

The present invention has been made in order to solve the above problems, and when attention is paid to a portion to be operated in a display screen in a display system of a display device such as a computer or a word processor, It is an object of the present invention to obtain a display method in which a part and the remaining part are displayed with a relationship suitable for the purpose.

[0007]

In order to solve the above problems, a display system according to the first invention comprises means for selecting a part on a display screen, means for enlarging the selected part, and Means for reducing or deforming the other portion in accordance with the enlargement of one portion is provided.

The display system according to the second aspect of the present invention is, in addition to the first display system, further provided with means for continuously moving the enlarged area.

The display system according to the third aspect of the invention is provided with means for selecting a plurality of portions on the display screen and means for enlarging the plurality of selected portions.

The display system according to the fourth aspect of the present invention is provided with means for selecting a part of the window in the window system and means for enlarging the selected part by using another window.

In the display system according to the fifth aspect of the present invention, when the partial area 1 on the display screen is enlarged, a means for selecting the partial area 2 in the enlarged partial area 1 and the partial area 2 are enlarged. The means for doing so is provided.

Further, in the display system according to the sixth aspect of the present invention, when a part of the display screen is enlarged, the enlarged region is displayed on the display screen before enlargement as if it were semitransparent. Means are provided.

Further, the display system according to the seventh invention is provided with, for example, means for selecting an arbitrary line on the screen when only characters are displayed and means for displaying only the one line. Is.

[0014]

According to the display methods of the first and second inventions, even if a part is enlarged, the peripheral portion is deformed / reduced, so that the information amount and the layout of the entire display screen can be kept constant before and after the enlargement. The display screen before enlargement is not damaged.

Further, according to the third invention, a plurality of locations can be selected and enlarged, so that distant portions can be enlarged and displayed at the same time.

According to the fourth invention, since the image is enlarged using another window, the information before and after the enlargement can be referred to at the same time.

According to the fifth aspect, a part of the enlarged area can be further enlarged, so that it is possible to roughly enlarge at a low magnification and display a portion at a high magnification in more detail. .

According to the sixth aspect of the present invention, by making the enlarged portion semitransparent, the display screen before enlargement is not damaged.

According to the seventh invention, for example, when a character is displayed, only the necessary lines can be displayed, so that even if the number of characters is large, it is not confused with other lines.

【Example】

Example 1. The configuration for carrying out the present invention is the same as in FIGS. 16 and 17 of the first conventional example. However, in the management table 58 shown in FIG. 17, the enlargement ratio (n) and the enlargement area size (a,
b), the position of the mouse cursor, the upper limit of the number of windows (M
W), the current number of windows (W), the position and enlargement ratio of the mouse cursor, the line number of the cursor, etc. are stored.

FIG. 1, FIG. 2 and FIG. 9 are views showing an embodiment of the invention described in claims 1 and 2. In the figure, 1 is a screen, 2 is a mouse cursor, 3 is a rectangular enlarged region, 4 is the width of the screen 1, 5 is the height of the screen 1, 6 is the width of the enlarged region 3, and 7 is
Is the height of the enlarged region 3, 8 is the region enlarged in the lateral direction, and 9 is
Is an area enlarged in the vertical direction, 10 is an area reduced in the horizontal direction, and 11 is an area reduced in the vertical direction.

The operation will be described. In FIG. 1, a mouse cursor 2 is displayed on a screen 1 of a window system such as an X window. When the mouse cursor 2 is moved to a portion to be enlarged and displayed and the mouse button is pressed, the inside of the rectangular enlargement region 3 centering on the mouse cursor 2 is enlarged while the mouse cursor 2 is pressed. At the same time, the area 10 is horizontally reduced and the area 11 is vertically reduced, so that the amount of information displayed on the screen 1 is kept the same as before the area 3 was enlarged. However, the reduction ratio at this time is uniquely determined by the size of the enlargement area 3 and the enlargement ratio. That is,
If the ratio of the width 4 of the screen 1 to the width 6 of the enlarged region 8 is 1: a, the ratio of the height 5 of the screen 1 to the height 7 of the enlarged region 8 is 1: b, and the enlargement ratio is n, the reduction ratio is Is (1-a) / (1-
a / n) and the vertical direction is (1-b) / (1-b / n). When the mouse cursor is moved (draged) while the mouse button is pressed, the enlargement area and the peripheral reduction area move accordingly.

FIG. 9 is a flow chart showing the processing of claim 1. In FIG. 9, reference numeral 12 denotes an operation start step, in which a display system to be described below can be executed by an appropriate operation (such as setting an interrupt key). The position of the mouse cursor 2 is recognized at 13. In the normal window system, the mouse cursor 2 is displayed somewhere on the screen 1, and the movement of the mouse is recognized as the displacement amount of the mouse cursor 2, and the mouse cursor 2 is displayed on the screen 1 as in 14. . At this time, if the mouse button is pressed (15), the rectangular area 3 centered on the mouse cursor 2 is enlarged, and the peripheral area is reduced accordingly (16). If the mouse button is not pressed, the scaling is not performed. Here, returning to 13 and updating the position of the mouse cursor 2, the same processing is repeated. Therefore, if the mouse is kept in a dragged state, the enlarged area moves following the movement of the mouse cursor 2. The enlargement ratio (n) and the size (a, b) of the enlargement area 3 are stored in the management table 58 of FIG. 17 as described above.

As described above, in this embodiment, in the display system in the window system such as the X window, the means for selecting a part of the display screen, the means for enlarging the selected part, and enlarging or transforming the display screen. It is characterized by having means for keeping the amount of information and the layout of the entire screen constant.

Example 2. In the first embodiment described above, the case of enlarging both the width direction and the height direction of the screen has been described, but it is also possible to enlarge only the width direction or only the height direction.

Example 3. In the first embodiment described above, the case of enlarging the character is illustrated and described, but the information existing in the designated area does not have to be the character,
Other information such as graphic information and photo information may be used.

Example 4. 3 and 10 are views showing an embodiment of the invention described in claim 3. In FIG. 3, 1
Reference numeral 7 is a circular enlarged area.

The operation will be described. The operator moves the mouse cursor 2 to an arbitrary position to enlarge and clicks a mouse button. Then, a circular enlarged region 17 centered on that position appears, and the display inside is enlarged. By repeating this operation, a plurality of areas can be enlarged and displayed. When it is desired to delete the generated enlarged area 17, the mouse cursor 17 may be brought into the unnecessary enlarged area 17 and clicked. Figure 10
Is a flow chart showing the flow of the processing. First, in the operation start step of 18, an instruction to shift to a state in which this method is executed is instructed by an appropriate interrupt operation. Next, at 19 the two positions of the mouse cursor are recognized,
At 20, the mouse cursor 2 is displayed. At this time (21)
If the mouse is clicked, it is determined whether the area is an expandable area (22). The expandable area is an area in which the plurality of expanded areas 17 do not overlap each other. Specifically, assuming that the radius of the expanded area 17 is R1, it is 2 × R1 or more away from the center of all the existing expanded areas. It is a set of existing points. If the area is an expandable area, the expanded area 17 is generated at 24, and the position of the mouse cursor 17 is registered in the management table 58 shown in FIG. This information is used to determine the expandable area. On the other hand, if the area is not the expandable area at 22 and is already the expanded area, the expanded area 17 is deleted by clicking the mouse, and the original display is restored (25).

As described above, this embodiment is characterized by having means for selecting a plurality of portions on the display screen and means for enlarging all the selected portions.

Example 5. In the fourth embodiment, the case where the enlarged area does not overlap with other enlarged areas has been described. However, when the area designated as the enlarged area overlaps with another already enlarged area, No processing may be performed on the overlapping portions, and the enlargement processing may be performed on a portion of the newly designated area that does not overlap another enlarged area.

Example 6. In the fourth embodiment described above, the case where a plurality of enlargement areas are designated has been described.
As described above, it is possible to specify both the enlarged rectangular areas and reduce the other portions. That is, the functions of both the first and fourth embodiments may be provided.

Example 7. FIG. 4, FIG. 5 and FIG. 11 are views showing an embodiment according to claims 4 and 5. In FIG. 4, 26 is a rectangular enlarged area, 27 is a window in the window system, and 28 is a window generated for enlarging and displaying the enlarged area 16. 29 in FIG.
Is a window generated for further enlarging and displaying the enlarged area 26 designated in the window 28 generated for enlarging.

The operation will be described. Mouse cursor 2
The rectangular enlarged area 26 centered at is always displayed and moves in conjunction with the movement of the mouse cursor 2. Move the mouse cursor 2 to the area you want to enlarge, and click the mouse button when you reach the desired location. Then, a window 28 for enlarging and displaying the enlarged area 26 is generated. When the same operation is performed inside the window 28, a window 29 having a higher magnification shown in FIG. 5 is generated.

FIG. 11 is a flow chart showing the flow of the processing, which will be described. In the operation start step of 30, an interrupt operation is instructed to shift to a state in which this method can be executed. As a result, a rectangular enlarged area 26 centered on the mouse cursor 2 is generated.
The position of the mouse cursor 2 is recognized at 31 and the mouse cursor 2 and the enlarged area 26 are displayed at 32. If the mouse is clicked in 33, the number of windows that are currently open (W) is determined from the upper limit of the number of windows that can be opened at the same time (MW), which depends on the window system used. Determine whether it is small. If it is less than the upper limit value, a new enlarged display window 28 is generated at 35, and if the upper limit value is reached, no window is generated. The upper limit value MW of the number of windows and the number W of currently open windows are stored in the management table 58 of FIG. 17 described above, as in the case of the first embodiment. For operations such as window deletion and movement, the functions provided by the window system used are used.

As described above, this embodiment has means for selecting the partial area 2 in the partial area 1 when the partial area 1 on the display screen is enlarged, and means for expanding the partial area 2. Is characterized by.

The operation will be described. While dragging the mouse cursor 2, a rectangular enlarged area 36 is generated with the mouse cursor 2 at the center,
Enlarge the data in the area. The enlarged area 36 moves in association with the movement of the mouse cursor 2. Expansion area 3
When 6 is displayed, a portion where the original display and the display by the enlarged region 36 overlap is displayed in a pseudo double manner by uniformly allocating each half of the display pixel. The flow of processing is the same as in FIG. 9 which is the flowchart of the first embodiment, but pixel division may be added to the portion of the enlargement / reduction processing 16 in FIG. Enlarged area 36
The size, the position of the mouse cursor, the enlargement ratio, and the like are stored in the management table 58 of FIG. 17 described above, as in the first embodiment.

As described above, according to this embodiment, when a part of the display screen is enlarged, a means for displaying the enlarged region on the display screen before the enlargement as if it is semitransparent is provided. It is characterized by having.

Example 9. In the above-mentioned Example 8, the double display is made by dividing the display pixels into halves in the overlapping display areas.
One of the displays is displayed using all the pixels as before,
The other display may be displayed with half the pixels of the display. Alternatively, both displays may be displayed using all pixels.

Example 10. In the eighth embodiment, when the information is displayed double, it is displayed by allocating the pixels of the display in half, but it may be displayed without allocating the pixels of the display.
For example, the brightness of one piece of information may be weakened and the brightness of the other piece of information may be increased so that the information is displayed double. Alternatively, the color of one information may be displayed by being distinguished from the color of the other information.

Example 11. FIG. 7, FIG. 8 and FIG. 13 are views showing an embodiment of the invention described in claim 7. In FIGS. 7 and 8, 37 is a cursor and 38 is a line on which the cursor is located. The operation will be described. As shown in FIG. 7, when only the character is displayed on the screen 1, the operator puts the system into a state of being executed by an appropriate means. Then, only the line where the cursor 37 exists is displayed, and the other lines disappear from the screen 1. When the cursor 37 is moved, the display line also moves. FIG. 13 is a flowchart showing the flow of the processing. First, in the operation starting step of 39, the one-line display mode is entered. Cursor 3 at 40
The position of 7 is recognized, and the cursor 37 is displayed at 41. Next, at 42, it is judged whether or not the current mode is the one-line display mode. If not, only one line where the cursor 37 exists is displayed (43), and if not, all lines are displayed (4
4) and check the position of the cursor 37 again (3
9). In this way, when the cursor 37 is moved in the vertical direction, the line displayed is also moved accordingly. The line number where the cursor 37 exists is stored in the management table 58 of FIG. 17 described above, as in the first embodiment.

As described above, this embodiment is characterized in that, when only the character is displayed, or in the character display, it has means for selecting an arbitrary line on the screen and means for displaying only the one line. And

Example 12 In Example 11 above,
I explained the case where the character display device is displaying a character, but not only displaying one line with the cursor and erasing other lines, but also specifying multiple lines by specifying the cursor and erasing other lines. I don't mind. Alternatively, by designating a specific word or a specific phrase in one line, other parts may be erased. Further, not only when displaying a character but also when displaying a figure or a drawing, a specific area may be designated on the screen and information other than that area may be erased.

[0043]
