Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device, and more particularly to an image display device for displaying a predetermined portion of a designated original image in a display frame.

[0002]

2. Description of the Related Art Conventionally, an image or the like input as data is combined with an image in accordance with an instruction from an operator.
There is known an image processing system capable of performing various editing processes such as cutting and pasting, enlarging and reducing, and creating and printing an arbitrary image desired by an operator. This type of image processing system is configured to include a display device such as a display, so that an image being created is displayed in the created image display area of the display screen of the display so that the operator can easily grasp the image being created. The image of the input image data is temporarily displayed in a work area outside the created image display area of the display screen of the display so that the operator can easily give various instructions. Has been done.

In the image processing system as described above,
The so-called cut-and-paste processing, in which a part of the image represented by the input image data (hereinafter referred to as the original image) is cut out and placed in the window of the created image display area designated in advance, displays the original image represented by the input image data. Completed by displaying in the work area of the screen, prompting the operator to specify the range of the cutout portion, displaying the image of the portion specified by the operator in the specified window, and deleting the display of the original image. To do.

[0004]

By the way, when the operator judges that the range of the portion cut out from the original image is not appropriate after the above cutting and pasting processing is completed,
The operator needs to perform the cutting and pasting process again to respecify the range of the portion to be cut out. However, since the display of the original image is erased at this time, it is difficult to determine which range on the original image should be set as the portion to be cut out, and the operator repeatedly performs cutting and pasting processing until an appropriate range is cut out. Therefore, it is necessary to perform complicated work such as re-designating the range of the cut-out portion.

In order to solve this, it is conceivable to continuously display the original image in a work area or the like on the display screen, but the work area is a display area used in various editing processes, and Since the display screen of the display is limited, it is not preferable to continuously display the original image after the cutting and pasting process is completed. Further, it is conceivable to continuously display a reduced image of the original image, but this also causes a problem that the display on the display screen becomes complicated.

The present invention has been made in consideration of the above facts, and an object of the present invention is to obtain an image display device which can easily specify a range to be cut out from an original image and displayed in a window.

[0007]

In order to achieve the above object, an image display device according to the present invention comprises a window display means for displaying a window indicating a boundary of an image display range on a display screen, and image data representing an original image. Storage means for storing
Based on the image data stored in the storage means and the specification means for specifying the range of the original image to be displayed in the window, an image corresponding to the range specified by the specification means is displayed in the window. The image display means for displaying and the contour display means for visually displaying the contour of the original image located outside the window are included.

[0008]

In the present invention, the window display means displays a window indicating the boundary of the image display range on the display screen. Further, there is provided a designating unit for designating a range to be displayed in the window in the original image, and the image displaying unit sets the range designated by the designating unit based on the image data stored in the storage unit. Display the corresponding image in the window. The contour display means visually displays the contour of the original image located outside the window.

Thus, the operator can easily recognize the relative position between the contour of the original image and the window, that is, the position in the original image of the image currently displayed in the window. Therefore, when the image once displayed in the window by the operator once designating the range to be displayed via the designating means is not the image of the desired portion of the original image, it should be designated via the designating means. Since the position of the range on the original image can be easily determined, the operator can easily specify the range to be cut out from the original image and displayed. Further, since the contour of the original image is displayed in the present invention, the display on the display screen becomes simple and clear as compared with the case where the original image itself is reduced and displayed outside the window.

The mouse 24 corresponds to the pointing means of the present invention.

Since the image display device of this embodiment handles all data including both image data and character data as document data, the detailed structure of the document data will be described first with reference to FIG. Document data includes a mount 102, a graphic frame 108, and a text frame 126.
It is composed of data indicating each of the above. The text frame 126 is an area for displaying character data.
An attribute, which is decoration information for determining the font, size, color, etc. of the character, can be added to 6.

A graphic frame 108 is an area for displaying an image,
It acts as a viewing window (window) for displaying the captured image in the graphic frame 108. The graphic frame can be provided with attributes that determine the magnification of the image displayed in the frame, the background transmittance of the image in the frame, and the like.

The captured image data itself can be treated as the same document data as above. That is, the second graphic frame is inserted into the image (first image) displayed in one graphic frame (first graphic frame) in a nested structure, and the second graphic frame is inserted in the second graphic frame. It is possible to display a second image on the. Furthermore, a third image frame is nested in the second image to display the third image, and a fourth image frame is nested in the third image to display the fourth image, It is possible to nest graphic frames.

A plurality of graphic frames having a nested structure have a vertical relationship, and when an image of a lower (nested side) graphic frame and an image of a higher (nested side) graphic frame overlap each other, a lower image Is obscured by the upper image and displayed. The vertical relationship of the graphic frame can be changed.

The above document data, that is, data representing the mount 102, the graphic frame 108, and the text frame 126,
The image data and the text data are stored in the RAM 10B as a whole file, and different external files (for example, a library file in which a plurality of image data are recorded in advance) are not referred to.

As described above, in this embodiment, the mount 102, the graphic data, and the graphic frame 108 each have a layer structure. That is, the image is located above the mount 102, and the graphic frame 108 that acts as a window on the image.
Has a laminated structure. This allows
During image editing, the captured image data is held and the position of the graphic frame is shifted by dragging, so that an image or character that has not been displayed in the graphic frame can be displayed.

It should be noted that the mount 102 always includes all the graphic frames 10
8 and the lower part of the text frame 126, and it is possible to draw directly on the mount 102.

Next, the flow of image editing will be briefly described.
As shown in FIG. 4, when a document creation menu (not shown) for creating a new document is selected, the mount 10
2 is displayed on the screen 100. Next, by using the mouse 24, the figure editing field 10 of the menu bar 105 at the upper end of the screen.
When 6 is selected, graphic editing is started.

As shown in FIG. 5, the cursor is positioned at the reference points 107 and 109 on the mount 102 and the mouse 2 is moved.
4 is clicked, a rectangular graphic frame 108 having the reference points 107 and 109 at both ends of the diagonal line is displayed on the mount 102.
Displayed above. Next, when an input menu (not shown) of either the full-color scanner 16 or the digital still camera 18 is selected, the work mount 110 is displayed, and the image reading is started by any of the selected image input devices and the reading is started. Original image 111 (in FIG. 5, copy machine 11
The original image including the image 2) is displayed on the work mount 110.

On the original image 111, it is possible to display a capture frame 115 indicating the range of a partial image for cutting the image and displaying it in the capture graphic frame 108. That is,
When the cursor is positioned at the reference points 114 and 116 at both ends of the diagonal line of the partial image displayed in the graphic frame 108 and the mouse 24 is clicked, these reference points 114 and 116 are displayed.
A take-in frame 115 having both ends of the diagonal line is displayed. The capture range can be changed by changing the positions of the reference points 114 and 116. The image in the capture frame 115 is displayed in the graphic frame 108 together with the end of the capture range instruction (for example, a confirmation instruction by clicking the mouse 24). This processing corresponds to the image display means of the present invention.

In the present embodiment, a plurality of graphic frames and text frames can be generated on one mount 102, and the image can be edited for each frame. When it is desired to combine another image in one image as shown in FIG. 3A, another figure frame 52 is generated inside one figure frame 50 on the screen. As a result, one image is combined with another image and displayed. At this time, if it is desired to combine only the image of the chair image 54 excluding the background among the images in the graphic frame 52 with the image in the graphic frame 50, an image other than the image 54 of the chair in the graphic frame 52 is used as the background. , The background transmittance is 10
If the attribute of 0% is given, as shown in FIG. 3B, in the graphic frame 50, the image of the chair 54 alone is combined and displayed on the image in the graphic frame 50.

Next, the character editing will be described. As shown in FIG. 6, the character edit field 124 of the menu bar 105 at the upper end of the screen is selected by the mouse 24. As a result, character editing is started. When the text frame 126 is designated by the mouse operation similar to the case of image editing with the graphic frame 122, the character input window 128 is displayed. When a character is input from the keyboard, the character string 130 is displayed on the character input window 128, and an input completion instruction (for example,
When you click the mouse), the character string 132 is displayed in the text frame 1
26 (see FIG. 7). When there is no correction here,
When an instruction to confirm editing (for example, clicking the mouse) is made, the character input window 128 is erased and the text frame 12
Edit 6 is confirmed (FIG. 8).

Next, referring to the flow chart of FIG. 13, for the image capture position changing process performed when it is desired to change the capture position from the original image with respect to the image once captured from the original image and displayed in the graphic frame. And explain. Note that, as shown in FIG. 9, this process instructs execution of the capture position changing process from among a plurality of icons (not shown) displayed in the command menu 118 previously displayed on the left side of the screen of the mount 102. After the cursor 104 is associated with the icon corresponding to the command
This is executed when the icon is selected by clicking the button.

In step 200, it is determined whether or not the designation of the graphic frame to be processed has been completed. If the graphic frame to be processed is designated in advance, step 20
The determination of 0 is affirmed and the routine proceeds to step 206. On the other hand, if the determination in step 200 is negative, the process stands by until a point in any of the graphic frames currently displayed on the mount 102 is designated in step 202. In addition,
FIG. 9 shows a state in which only a single graphic frame 122 is displayed on the mount 102 for simplification of description. When the determination in step 202 is affirmative, the graphic frame corresponding to the point designated in step 204 is stored as the graphic frame to be processed, and the process proceeds to step 206.

In step 206, it is determined whether or not the frame line of the graphic frame 122 designated as the processing target is designated (clicked), and the process waits until the frame line is designated. If the determination in step 206 is affirmative, step 2
08, the coordinates of the graphic frame 122 on the mount 102,
The position and size of the image displayed in the graphic frame 122 on the original image (the size of the graphic frame 122 and the graphic frame 12
2 is determined according to the display magnification of the image in 2), the position and size of the original image with reference to the mount 102 are calculated.

In the next step 210, a frame line 124 representing the outline of the original image is displayed based on the position and size of the original image calculated above. A frame line 12 representing this contour
For the display of No. 4, it is determined which part of the frame line 124 is inside the mount 102 and which part is outside, and the mount 102
The inner part of is shown with a broken line, and the outer part is shown with a solid line.
In the next step 212, a capture frame 120 (see FIG. 11) having the same size as the graphic frame 122 is displayed so as to overlap the graphic frame 122. In this state, the capture frame 120 and the graphic frame 122 overlap each other, so that the capture frame 120 is not shown in FIG. Note that this processing corresponds to the contour display means of the present invention.

In step 214, it is determined whether or not the mouse button has been released. When the determination in step 214 is negative, it is determined in step 216 whether the mouse instruction point (the position of the cursor 104) has been moved. If the determination in step 216 is also denied, the process returns to step 214 and waits until the determination in step 214 or 216 is affirmed. When the pointing point of the mouse is moved and the determination in step 216 is affirmative, the display position of the capture frame is moved in accordance with the movement of the pointing point of the mouse in step 218, and the contour is displayed as the frame line 124 in step 220. Of the displayed original images, an image corresponding to the range surrounded by the capture frame 120 whose display position has been moved is captured from the image data of the original image, the image is displayed in the graphic frame 122, and the process returns to step 214. . The processing of steps 218 and 220 also corresponds to the image display means of the present invention.

As an example, when the operator wants to display an image on the lower left side of the original image with respect to the image displayed in the graphic frame 122, as shown in FIG. 10, an arbitrary point of the frame line of the graphic frame 122 is displayed. Click and drag it to the lower left as shown in Fig. 11.
20 (indicated by a broken line in FIG. 11) moves in the lower left direction, and an image corresponding to the moved position of the capture frame 120, that is, an image on the lower left side with respect to the image displayed so far is displayed in the graphic frame 122. Is displayed. That is, the capture frame 12
0 is regarded as a virtual window, and an image corresponding to looking into the image data from that window is displayed in the graphic frame 122.

As described above, the image displayed in the graphic frame 122 is changed in real time to the image corresponding to the range surrounded by the moved capture frame 120. The operator uses a frame line 124 representing the outline of the original image.
And the graphic frame 12 based on the display position of the capture frame 120.
By easily deciding the position of the image displayed in 2 on the original image, and referring to the image displayed in the graphic frame 122 while moving the cursor 104 with the mouse button turned on, It is possible to easily determine in what direction and to what extent the cursor 104 should be moved in order to display a desired image in the graphic frame 122. Therefore, the graphic frame 122 is cut out from the original image.
The range to be displayed can be easily specified.

The operator releases the mouse button while the desired image is displayed in the graphic frame 122. As a result, it is determined that the edit confirmation is instructed, and the determination in step 214 is affirmative. As shown in FIG. 12, in step 22, the capture frame 122 and the outline display of the original image are erased, and in step 224, the inside of the graphic frame 122 is deleted. The coordinates of the image displayed on the original image are stored, and the process ends.

When the creation of the new document is completed as described above, the print field 134 is selected from the menu bar 105 at the upper end of the screen with the mouse 24, and the information of the fixed characters and figures on the mount 102 is sent to the printer 26. Output. The printer 26 prints based on the input data. As a result, a print of the edit screen on the mount can be obtained.

In the above description, the graphic frame 122 as a window is fixedly displayed, and the capture frame 120 having the same size as the graphic frame 122 is moved in response to the dragging by the mouse 24, and the image displayed in the graphic frame 122 is displayed. However, the present invention is not limited to this, and instead of displaying the capture frame 124, the display position of the graphic frame 122 is moved according to the dragging by the mouse 24. You may In addition, the frame line 1 representing the outline of the original image according to the dragging with the mouse 24
The display position of 24 may be moved. Furthermore,
When the display position of the figure frame 122 is moved, even if the figure frame 122 is continuously displayed at the display position of the figure frame 122 when the confirmation of the edit is instructed, when the confirmation of the edit is instructed. The image and the graphic frame 122 may be displayed at the original display position of the graphic frame 122 without changing the image displayed in the graphic frame 122.

In the above, the mouse 24 is used as an instruction means.
However, the present invention is not limited to this, and various pointing devices such as a light pen and a digitizer can be used. It is also possible to use the keyboard 28 as an instruction means.
