Abstract

PROBLEM TO BE SOLVED: To enable editing a dot image of a necessary part over a look at the whole image without enlarging and displaying the whole image by displaying a partially enlarged image over the entire image. SOLUTION: A 2nd information processor 14 has a display and a position- specifying means, such as a mouse. When the 2nd information processor 14 generates a request to edit a dot image, a 1st information processor 13 reads image data on a part to be edited, corresponding to position information that the mouse currently indicates out of an image data storage means 11 and transfers the data to a density-converting means 12. The density-converting means 12 enlarges the sent image data with specified magnification and converts the density to generate enlarged image data. The enlarged image data are transferred to the 2nd information processor 14 and superimposed on the entire image on the display. By moving the mouse the partially enlarged image can be viewed, while being moved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of partially enlarging and displaying an image in an image data editing system,
In particular, the present invention relates to an image partial enlarged display method for displaying an enlarged image of a designated portion of an image and an original image in an overlapping manner.

[0002]

2. Description of the Related Art Conventionally, when editing a dot image of an image, the entire image is enlarged and displayed by density conversion,
On the magnified image, edit the dot image at the designated location with a pointing device such as a mouse, or magnify the area centered around the designated position and display the entire image on another display area. Is displayed, the relationship between the enlarged partial image and the entire image is displayed and grasped in a plurality of display areas, and the partial enlarged image is edited.

FIG. 4A and FIG. 4 showing an example of a conventional enlarged display method according to Japanese Patent Laid-Open No. 63-1736169.
Referring to (b) and FIG. 4 (c), the target image 41 to be edited and the entire image 44 displayed in a small size are displayed in another window on the display screen 40 in FIG. 4 (a). Since a part of the target image 41 is designated and enlarged, FIG.
The enlarged designation portion 42 of (b) is designated by the pointing means and is displayed in reverse. A partially enlarged image 43 and an original whole image 44 shown in FIG.
By doing so, the relationship between the partially enlarged image and the entire image is grasped, and the dot image is edited.

In the display method of this publication, when the entire image is density-converted and enlarged and displayed, it becomes difficult to know which range in the image is enlarged and displayed. The reason is that when the entire image is enlarged and displayed, the size of the image is usually too large, and it becomes difficult to grasp the relationship with the entire image. Therefore, the part of the enlarged image that cannot be displayed is displayed using a means such as scrolling.

Further, in the display method of this publication, when the partially enlarged image and the whole image are displayed in different display areas, the editing operation becomes complicated. The reason is that when the dot image is to be edited for the entire image or many parts of the image, the dot image is edited by selecting the part to be enlarged and displayed from the image that is being displayed. When the dot image editing of the magnified area is completed, the process of selecting the area to be magnified again must be repeated, and the area magnified and the area to be magnified continuously continue. Attempting to see the sex usually results in several trials.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As in the case of viewing an image with a magnifying glass, the target portion is magnified and displayed over the entire image, and the enlarged portion moves on the image as the position of the target portion moves. There is a method of displaying images.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to simplify the operation for a user to edit a dot image at a specified position on an image by partially enlarging the image for each editing location. Therefore, the relationship between the entire image and the partially enlarged image can be easily grasped, and the partially enlarged image can be visually recognized while moving.

Therefore, in the method of displaying the image of the dot image of the present invention on the display of the processing device and enlarging and displaying the edit target portion of the image, an edit request is made to the displayed image. 1 step, a second step of acquiring position information designating a part to be edited of the image by pointing means, and a step of acquiring a partial image including the part to be edited from a storage means based on the position information. Step 3, a fourth step of generating a partially magnified image that has been subjected to dot density conversion for magnifying the partial image, and a fifth step of superimposing and displaying the partially magnified image on the image based on the position information. Step, and when the position information designating the portion to be edited moves on the image, the partially enlarged image based on the position information is the image. A sixth step that appears superimposed by moving the characterized in that it comprises a.

Only a specific range of a position pointed by a position designating means such as a mouse (hereinafter referred to as a mouse) is enlarged and displayed in an overlapping manner. This allows the user to easily understand which part on the image is enlarged. Furthermore, by simply specifying the position on the image that is displayed as a whole with the mouse, the partial image centered on that position is enlarged and displayed.As the specified position moves, the partial enlarged image moves over the entire image, as if It is the same when viewing a part of the image with a magnifying glass.

Next, the present invention will be described with reference to the drawings.

Referring to a flow chart showing a method according to an embodiment of the present invention, a first step of requesting editing of an image consisting of a dot image displayed on a display and a mouse on the image. A second step of specifying a position to acquire position information, a third step of acquiring a partial image of an area centered on the position from a storage unit, and a dot image of the partial image are density-converted and enlarged. A fourth step of generating an image, a fifth step of superimposing the enlarged image at the position of the position information with the original image, and a move of the mouse to update the position information. The sixth step of returning is included.

Referring to FIG. 2 showing the system configuration in which this embodiment is executed, the image data storage means 11 for storing the data of the target image for dot image editing of the display image and the image having an arbitrary size. Density conversion means 12 for density conversion when enlarging / reducing, and image data storage means 1
1 and the density conversion means 12 are provided with a first information processing device 13 for making an access request and a second information processing device 14. The first information processing device 3 has a central processing unit (CPU) and an internal memory which are not shown, and the second information processing device 4 has a display and a position designating means such as a mouse and a keyboard which are not shown. ing.

Referring to FIG. 3 showing the internal structure of the first information processing device 13, the image data storage means 11 responds to the partial image acquisition request based on the position information sent from the second information processing device 14. A system control unit 132 that controls access to the
The image data storage unit 11, the density conversion unit 12, and the image data I / O unit 131 that transfers the image data to the second information storage device 14 are included.

The method of this embodiment will be described below with reference to FIGS. 2 and 3 and FIG. Second information processing device 14
When a dot image edit request is issued from the device (step 1), the system control unit 132 acquires the position information currently pointed to by the mouse position designating means, and specifies the point corresponding to the position information as the center. A request for reading the image data of the size area is issued to the image data I / O unit 131 (step 2). The image data I / O unit 131 receiving the read request reads the image data corresponding to the read request (step 3). System control unit 132
Requests the image data I / O unit 131 to transfer the image data read by the image data I / O unit 131. The image data I / O unit 131 transfers the image data previously read by the density conversion unit 12 to the density conversion unit 12. The system control unit 132 instructs the density converting means 12 to a predetermined magnification. The density conversion means 12 enlarges the sent image data at a designated magnification and performs density conversion to create enlarged image data (step 4). The magnified image data is transferred to the image data I / O unit 131, and the system control unit 132 requests the image data I / O unit 22 to transfer the magnified image data to the second information processing device 14, and the image data I / O unit The O unit 131 transfers the enlarged image data to the second information processing device 14 and displays it on the display so as to overlap the entire image (step 5). When the position designation means such as a mouse moves to update the position information, the process returns to step 3 and the enlarged display of the partial image is repeated (step 6).

[0015]

As described above, the first effect of the present invention is that it is not necessary to enlarge and display the entire image. As a result, it becomes possible to edit the dot image of a required portion while viewing the entire image. Moreover, compared to the case where the whole is enlarged and displayed, the enlarged image of the designated portion can be simultaneously displayed by moving the mouse without using a means such as scrolling.

Further, a second effect of the present invention is to eliminate the complexity of repeating the operation of designating an enlarged portion on the image. Since the partial image centering on the position pointed by the position designating means such as a mouse is enlarged, it is troublesome to repeat the position designation by displaying the entire image and the enlarged partial image in different display areas. This is because the operation is lost.
