Abstract

[PROBLEMS] Conventionally, since a display image contains a graphic image, display data is large, a character image often does not fit within an enlarged range, and a plurality of character images may overlap. Many can be difficult to read. A search range around a mouse pointer is provided.
4. When the origin of the text 52b exists in the position 4,
The character “TEXT2” of the text 52b is enlarged and displayed as indicated by 55. This enlarged display does not perform only the images within the search range 54 in a loupe manner,
4 is performed for all the characters of the text 52b having the origin in 4. Therefore, even if the entire character does not fall within the search range 54, the entire character can be enlarged and displayed, and the display data can be reduced compared to the related art because only the text information is enlarged without including the graphic data. In addition, the enlarged display targets one text closest to the mouse pointer 53.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display method and a display device, and more particularly, to a display method and a display device capable of confirming text (TEXT) information in a layout editor and a circuit diagram editor.

[0002]

2. Description of the Related Art Conventionally, graphic processing devices such as CAD, layout editors, and circuit diagram editors display images such as created characters and graphics on a screen of a display device.
An arbitrary image is selected using a pointing device such as a mouse or a digitizer. In this case, various display devices for enlarging the image displayed on the screen to a size that can be easily edited have been conventionally proposed (JP-A-6-4607, JP-A-7-325930,
JP-A-10-133639).

For example, in the conventional first display device described in Japanese Patent Application Laid-Open No. 6-4607, when a mouse cursor is moved to a screen area, a loupe display area of a predetermined size is displayed, and a mouse cursor is displayed inside the loupe display area. In this configuration, the data to be edited centered on the position of the tip of is edited and displayed. According to this conventional device, for example, “TE” shown in FIG.
When the character image (text information) 81 of "XT" is displayed in an enlarged manner, the mouse pointer (mouse cursor) 82 is moved in the direction of the display position of the character image 81 to display the character image 81 as shown in FIG. When reaching the position, a part of the character image 81 in the enlarged area 83 around the mouse pointer 82 is enlarged and displayed. Note that a small area 84 centered on the mouse pointer 82 is a graphic acquisition range.
Further, when the mouse pointer 82 is moved, the enlarged area 83 is also moved accordingly, and as shown in FIG.
Another character portion of the character image 81 of "XT" is enlarged and displayed in a loupe manner.

[0004] The display devices described in the above-mentioned JP-A-7-325930 and JP-A-10-133039 are also disclosed.
Similar to the display device described in Japanese Patent Application Laid-Open No. 6-4607, an image within a certain range of the position indicated by the mouse cursor is enlarged.

[0005] In addition, a second conventional method for enlarging and displaying a character image is disclosed.
Is known as a display device having a configuration in which all character images are uniformly enlarged and displayed. In this conventional second display device, when graphic images 91a to 91c and character images 92a to 92c are displayed on a screen, for example, as shown in FIG. As shown by 93a to 93c in FIG. 9B, 92a to 92c are uniformly enlarged and displayed. The enlarged and displayed character images 93a to 93c are shown in FIG.
As shown in 92c, the original size can be restored by a predetermined operation.

Further, a conventional third method for enlarging and displaying a character image is disclosed.
There is known a display device having a configuration in which a target character image and a range around the target character image are designated, and an image within the range is enlarged and displayed. In this conventional third display device, for example, as shown in FIG. 10A, graphic images 11 and 12 (here, layout figures in a layout editor or the like) and a character image 13 of “TEXT” which is a terminal name and the like are displayed. When the range 14 is designated for an image in which the characters are mixedly displayed, the graphic images 11 and 12 in the range 14 are 11a and 12a, respectively, and the character image 13 is displayed as shown in FIG. Are enlarged and displayed at a desired display magnification as shown by 13a. The original image shown in FIG. 10A can be obtained by returning the enlarged image within the range 14 to the original display magnification by a predetermined operation as shown in FIG. 10C.

[0007] Further, the conventional fourth method for enlarging and displaying a character image is disclosed.
As a display device, there is also known a display device in which a display magnification of a character image is designated by a command, and a character image to be enlarged is selected by a mouse and enlarged and displayed.

[0008]

However, in the above-mentioned conventional first display device, there is a first problem that the display data becomes large because the display image contains a graphic image. Since only the image around the mouse pointer is enlarged and displayed, the character image often does not fit within the enlarged range. In this case, there is a second problem that the entire character image cannot be enlarged and displayed.

In the above-mentioned conventional second display device,
Since all character images are enlarged and displayed uniformly, FIG.
As shown in (B), a plurality of character images often overlap each other, and in this case, reading is difficult.
Problem arises.

[0010] In the above-mentioned conventional third display device,
Since the enlarged image also includes a graphic image as shown in FIG. 10B, the first problem that the display data becomes large similarly to the above-described first display device, and the entire character image There is a second problem that the display cannot be enlarged.

Further, in the above-mentioned fourth conventional display device,
Since the information of the character image is changed, the character image once enlarged remains enlarged, and there is a fourth problem that the character image does not return to the original size. Has a fifth problem that operability is poor because it is necessary to specify a target character image, so that an operation of selecting the target character image is required.

The present invention has been made in view of the above points, and has as its object to provide a display method and a display device that can enlarge a character image without changing the magnification of the entire display.

It is another object of the present invention to provide a display method and a display device capable of enlarging and displaying a character image without changing the character image information.

Still another object of the present invention is to provide a display method and a display device capable of displaying an enlarged character image in an easily readable state.

Still another object of the present invention is to provide a display method and a display device which enable confirmation of character image information without inputting a command or the like.

[0016]

To achieve the above object, according to an aspect of the display method of the present invention, on a screen and a text image and <br/> graphic image having the origin is displayed in a mixed manner, moving Provide a search range of any size around the free mouse pointer, search for the origin of the text image within the search range , and if there is one origin within the search range, set it at that origin. When there are a plurality of origins, the text image corresponding to the origin closest to the position of the mouse pointer is enlarged and displayed at a desired display magnification.

Further, in order to achieve the above object, a display device according to the present invention includes an input device for moving at least a mouse pointer on a screen in an arbitrary direction, and a search range storing an arbitrarily set search range. A storage unit, a magnification ratio storage unit that stores a text magnification ratio set arbitrarily, a text origin storage unit that stores the coordinates of the origin provided for each text image on the screen, and a screen. searching the text information storage section for storing information of a text image above, read the search scope from the search range storing unit, the origin of the text image within the search range around the mouse pointer on the screen, the origin If there is one
When the origin of a plurality of text images exists within the search range, a text search means for searching for one origin closest to the mouse pointer, and an origin corresponding to the origin searched by the text search means Text information is read from the text information storage unit, and text enlargement means for outputting display data for displaying an image based on the text information at the enlargement magnification read from the enlargement magnification storage unit, and display data from the text enlargement means. Based on

According to the present invention, a text image corresponding to one origin existing in a search range of an arbitrarily set size around the mouse pointer can be enlarged and displayed at a desired display magnification.

Further, when the present invention detects that the origin of a text image enlarged and displayed outside the search range by moving the mouse pointer, the enlarged text image is displayed. The display magnification is restored to the display magnification.

Further, the present invention is characterized in that, when a graphic image exists along with the origin in the search range, only the text image corresponding to the origin is enlarged and displayed at a desired display magnification.

[0021]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of an embodiment of the display method of the present invention. In the layout editor or the circuit diagram editor, as shown in FIG. 1A, character images (hereinafter referred to as text) of "TEXT1,""TEXT2," and "TEXT3" representing layout graphics 51a to 51c and their node names or terminal names. 52a, 52
The position coordinates of the mouse pointer 53 at the center of the search range 54 are obtained on the screen where the characters b and 52c are mixedly displayed, and the text 52 is entered into the search range 54 from the position coordinates.
A search is performed to determine whether the origin of a to 52c exists.

The origin of the texts 52a to 52c to be searched is one that is closest to the mouse pointer 53. When the mouse pointer 53 is moved, the search range 54 is similarly moved in accordance with the movement, and as shown in FIG. 1B, when the origin of the text 52b exists within the search range 54, the text 52b The character "TEXT2"
Are enlarged and displayed as indicated by 55 in FIG. This enlarged display does not perform only the image within the search range 53 in a loupe manner, but as shown by 55 in FIG.
This is performed for the entire character "TEXT2" of the text 52b having the origin within the search range 54. Therefore, search range 5
Even if the entire character does not fit in 4, the entire character can be enlarged and displayed.

As shown in FIG. 1B, even if a part of the layout graphic 51b is included in the search range 54, the enlarged display is performed only by the text 52b having the origin in the search range 54. Is the only character “TEXT2”. Therefore, since only text information is expanded without graphic data, display data can be reduced as compared with the related art, and the text content can be confirmed without changing the display magnification of the editor. In addition, since the enlarged display targets one text closest to the mouse pointer 53,
Enlarged display is not performed in a state where the text information overlaps with other text information, and the contents of the text information can be easily confirmed, and the text information can be confirmed without omission.

Thereafter, the mouse pointer 53 is further moved, and the search range 54 is similarly moved in accordance with the movement, and as shown in FIG.
When the origin of b does not exist, the character "TEXT2" of the text 52b returns to the original display magnification as indicated by 52b in FIG. 1C. Thus, according to the present embodiment, it is possible to easily check the text information without changing the display state of the editor and without inputting a command or the like.

Here, in the layout data and the circuit diagram data, a text is added to represent a terminal name or a node name. Therefore, the origin of the text used as the terminal name or the node name is actually The origin of the text is important because it must be on the data corresponding to the terminal or node. In the present embodiment, among the texts near the mouse pointer 53, the text having the origin within the search range 54 is enlarged and displayed, so that the origin of the text can be easily confirmed.

Next, a display device according to the present invention which embodies the above-described method of the present invention will be described. FIG. 2 is a block diagram showing an embodiment of the display device according to the present invention. As shown in FIG. 1, the display device includes an input device 1 such as a keyboard and a mouse, a computer (central processing unit) 2 that operates under program control, and a storage device 3 that stores information.
It comprises an output device 4 such as a display device.

The central processing unit 2 includes a text search unit 21
And text enlarging means 22. The storage device 3 includes a search range storage unit 31, an enlargement magnification storage unit 32, a text origin storage unit 33, and a text information storage unit 34. The search range storage unit 31 stores a text search range. The search range is determined by the user. The magnification storage unit 32 stores a text magnification. The magnification is determined by the user. The text origin storage unit 33 stores the origin coordinates of the text searched by the text search means 21. The text information storage unit 34 stores information of each text.

The text search means 21 reads the search range from the search range storage 31, and searches for the origin of the text within the search range. The origin of the text to be searched is searched for one closest to the position coordinates of the mouse pointer. The text enlargement unit 22 enlarges the text searched by the text search unit 21 at the enlargement ratio read from the enlargement ratio storage unit 32 and with the text information read from the text information storage unit 34.

Next, the operation of the display device of FIG. 2 will be described with reference to the flowcharts of FIGS. First, an enlargement magnification N for enlarging and displaying a text is set (step 101 in FIG. 3). The set magnification is stored in the magnification storage unit 32. In this case, there is a method of setting a font size and an enlargement size instead of the enlargement magnification. Further, a search range A around the mouse is set (step 102 in FIG. 3). The set search range is stored in the search range storage unit 31. The setting of the magnification N and the search range A can be arbitrarily performed using the input device 1 or another means.

Thereafter, while the mouse pointer is being moved on the screen by the input device 1, the text search means 21
Always obtains the position coordinates of the mouse pointer, and searches the search range read from the search range storage unit 31 centered on the obtained position coordinates of the mouse pointer for the origin of the text (step in FIG. 3). 103), when there is one origin in the search range, the origin coordinates are obtained, and when there are multiple origins, one origin coordinate closest to the position coordinate of the mouse pointer is acquired together with the text data of the origin (FIG. Third step 104), the origin coordinates are stored in the text origin storage unit 33, and the text data is stored in the text information storage unit.

Subsequently, it is constantly monitored whether or not the origin coordinates closest to the acquired position coordinates of the mouse pointer have changed (step 105 in FIG. 3). Information storage unit 34
Text data read from the
1 is output to the output device 4 at the enlargement magnification N read from the enlargement magnification storage unit 32 through the enlargement magnification storage unit 32, and enlarged and displayed on the screen (FIG.
Step 107).

On the other hand, if the origin coordinates closest to the mouse pointer position coordinates obtained in step 104 are different from the previously obtained origin coordinates (when the mouse pointer position coordinates change but the origin coordinates cannot be obtained anymore) The text enlarging means 22 includes the text information storage unit 3
The text data corresponding to the previous origin coordinates read out from step 4 is output to the output device 4 and displayed on the screen at the original magnification (step 106 in FIG. 3).

Subsequently, it is determined whether or not the enlarged text display has been completed (step 108 in FIG. 3). If not, the process returns to step 103 again. Hereinafter, the processing of steps 103 to 107 is repeated until the end of the enlarged display.

3 by the text enlarging means 22 of FIG.
As shown in FIG. 4, the operation of the enlarged display of the text in step 107 is performed by enlarging the text by text × magnification (step 201) and displaying the text in accordance with the origin of the text (step 202).

Next, a specific example will be described. FIG.
As shown in (A), a search area 54 is provided around the mouse pointer 53. As shown in FIG. 1A, the search range 54
If the origin of the text does not exist, the text is not enlarged. By moving the mouse pointer 53, as shown in FIG.
If the origin of "T2" exists, the text "TE
“XT2” is enlarged and displayed as indicated by 55 (steps 103 to 105, 107).

Thereafter, when the mouse pointer is moved and the origin of the text is out of the search range 54 as shown in FIG. 1C, the mouse pointer is moved to step 105 via step 103 in FIG. Since the position coordinates have changed but the origin coordinates cannot be obtained, it is determined that the origin coordinates have changed from the previously acquired origin coordinates.
In step 6, the enlarged display of the previous text "TEXT2" is stopped, and the display is returned to the original display magnification as shown in FIG.

When the display text image is the one shown in FIG. 7A in the normal display state, only the text is enlarged and displayed as shown in FIG. 7B in the enlarged display.

Next, a second embodiment of the present invention will be described with reference to the drawings. The configuration of the display device of the second embodiment is the same as that of the first embodiment of FIG. 2, but the text display method is different from that of FIG. The operation of the second embodiment will be described with reference to the flowcharts of FIGS. 3 and 5 and FIG.

The operation of this embodiment is performed in substantially the same manner as in the flowchart of FIG.
The operation according to the flowchart of FIG. That is, first, the magnification N set in step 101
(Step 301 in FIG. 5). Subsequently, a display area for displaying text information is secured (step 302 in FIG. 5). Further, it is displayed in reverse video in accordance with the origin of the text (step 303 in FIG. 5). Thus, the display text is as shown in FIG.

Next, a third embodiment of the present invention will be described with reference to the drawings. The operation of this embodiment is performed in substantially the same manner as the flowchart of FIG. 3, but the operation of the flowchart of FIG. 6 is performed instead of step 107 of FIG. That is, first, the text is enlarged to the magnification N set in step 101 (step 4 in FIG. 6).
01). Subsequently, the text is displayed in accordance with the origin of the text (step 402 in FIG. 6). Subsequently, text information is output as voice (step 403 in FIG. 6). Thus, the display text is as shown in FIG. In addition, voice information of the text information is output simultaneously with the display.

Next, a fourth embodiment of the present invention will be described with reference to the drawings. The operation of this embodiment is performed in substantially the same manner as in the flowchart of FIG. 3, but the display when it is determined in step 105 that the closest origin coordinate has changed is returned to the original display in step 106. Instead, the enlarged display is maintained by the user's specification. Thus, the display image is as shown in FIG.
The enlarged display state of the text indicated by 55 in (B) is enlarged as shown in FIG. 1C even if the mouse pointer 53 and its search range 54 move outside the origin of the text 52b. to continue.

[0042]

As described above, according to the present invention,
It has the following various features.

(1) Since only the text information is enlarged and displayed, the contents of the text can be confirmed without changing the display magnification of the entire editor.

(2) Since the text information is enlarged and displayed by referring to the contents of the text information, the text information to be enlarged can be kept unchanged, and the origin of the enlarged and displayed text information is out of the search range of the mouse pointer. When this happens, the text information can be returned to the original display magnification.

(3) Even if the entire text does not fall within the search range, the entire text can be enlarged and displayed, so that the text information can be checked without omission.

(4) Even if a part of a graphic is included in the search range, only the text information in the search range is enlarged and displayed. Can be reduced.
