In particular, in an image data processing apparatus equipped with a display device that displays a scroll bar on a display screen and has a function of controlling the position of image data displayed on the screen, the display area of the scroll bar is operated with a pointing device. The present invention relates to an image data processing device which allows a display image size to be selected with a high degree of freedom and improves operability.

Specifically speaking, firstly, the pointing device 2.
Using two buttons, one button allows you to control scrolling as before, and the other button allows you to select the display image size, and by calculating the corresponding display magnification and performing scaling processing, you can select the desired image. The present invention relates to an image data processing device in which areas are displayed.

Second, on the left and right and top and bottom of the scroll bar display area,
The present invention relates to an image data processing device that has a display area for marks for changing the image size, and allows instructions for changing the image size to be given by operating these marks with a pointing device.

Thirdly, by dividing the display area of the horizontal and vertical scroll bars into two and manipulating one display area, you can create an image with the upper left corner or lower right corner of the currently displayed image area fixed. The present invention relates to an image data processing device that allows a desired image area to be displayed at a specified magnification by allowing the user to select an image data extraction position (e.g., selection of an image data extraction position).

2. Description of the Related Art Image data processing apparatuses having functions of inputting, storing, searching 9 displaying, printing, converting 9 editing, and the like of image data of technical students are conventionally known.

Examples of image data processing devices include electronic filing devices that use large-capacity storage devices such as magneto-optical disks to register, search, and collect image data;
There are various image processing devices such as TP (desk top publishing), WP (word processor), and computer graphics processing devices equipped with software for drawing functions.

When displaying an image in such an image data processing device, such as an electronic filing device, the resolution of the image input from a scanner, facsimile, etc. and held in the image memory is generally the same as the resolution of the display device. higher than

Therefore, for example, when displaying an A4-sized document as is on a display device, it is not possible to display all images on one screen.

Specifically, for example, when an A4-sized document is read by a scanner with a resolution of 300 dpi, the number of dots in the main scanning direction is 2,480 dots, and the number of dots in the sub-scanning direction is 3,508 dots. Become.

On the other hand, a 1 display device is a common type and has a 1.0
Since the display capacity is 24x768 (dots), only a portion of the loaded image can be displayed.

Furthermore, since the resolution of a display device is usually about 100 dpi, there is another problem in that if a read original is displayed as is, the image will be displayed in a larger image size than the actual size.

Therefore, for example, in conventional electronic filing devices, when displaying an image, the display magnification is changed by performing thinning processing or scaling processing to allow the operator to display the image at the desired size. A change function is provided.

FIGS. 12 and 13 are diagrams each showing an example of a menu screen for changing display magnification in a conventional electronic filing device. In the drawings, PM indicates a pop-up menu, and PC indicates a pointing device cursor.

As shown in FIG. 12, when changing the display magnification, a pop-up menu PM for changing the display magnification is displayed in a window at the top of the screen.

When an item of this pop-up menu PM is selected with the pointing device/cursor PC, the image is scaled and displayed on the screen.

FIG. 12 shows the case where "resolution" is selected.

Moreover, FIG. 13 shows the case where "whole" is selected.

In this way, the display magnification can be changed by selecting a desired item on the pop-up menu PM for changing the display magnification by operating the pointing device.

However, with this conventional method, only a limited number of display types can be selected. For example, on the screens shown in FIGS. 12 and 13, "1x" and "2x" are displayed.

There is an inconvenience in that it is only possible to select from four options, ``resolution'' and ``overall,'' and it is not possible to select a display image size with a high degree of freedom.

Furthermore, display devices have been known that have a function of displaying a scroll bar on the screen and controlling the display area of the original image of the image data displayed on the screen by operating the scroll bar with a pointing device. It is being

As shown in FIG. 14 (2), the image of the image area ID on the image memory in FIG. 14 (1) is displayed on the screen of the display device, and the upper and lower The direction scroll bar VS is in the lower area,
Scroll bars H8 in the left and right directions are displayed.

These scroll bars vs and H8 cover the entire display screen.
When considering the entire image memory in FIG. 14 (1), currently,
It shows the vertical and horizontal areas corresponding to the image area ID actually displayed on the screen.

In this way, the scroll bar has the function of visually representing the display area of the currently displayed image data in its original image area, and the operator can:
Depending on the display state of this scroll bar, it is possible to easily understand which part of the entire image is currently displayed.

This scroll bar also has another function, as its name suggests, to scroll the screen.

In other words, by clicking the display area of the scroll bar VS, H3 with a pointing device and moving it up and down or left and right, the area displayed on the screen can be moved (scrolled), so the operator can see the entire image. You can easily select the part you want to see. For details, please refer to

In the image data processing apparatus of the present invention shown in FIG.
Different functions are assigned to the left button and right button of the pointing device, and when the display magnification setting mode is set, the pointing device/button detection section 2, the scroll control section 6, and the variable magnification processing section 10 Executes scaling processing corresponding to the specified display magnification.

To facilitate understanding, first, parts common to conventional image data processing devices will be explained.

The pointing device interface unit 1 has a function of controlling the hardware interface of a pointing device connected to the interface unit 1.

The pointing device/button detection section 2 detects whether a button of the pointing device is clicked (pressed) based on a signal inputted via the pointing device/interface section 1. In the image data processing device of the present invention, different controls are performed depending on the type of button (for example, right button and left button), and this point will be explained in detail later.

The pointing device coordinate position conversion unit 3 converts a signal inputted through the pointing device interface unit 1 into coordinate position data on the display device.

The pointing device drawing section 4 draws a pointing device cursor at the coordinate position on the display device given by the pointing device coordinate position conversion section 3. In drawing this cursor, a process of writing a pattern of a predetermined shape into the frame memory 5 is performed.

The frame memory 5 is a so-called bitmap type memory, and the image and cursor pattern data written in this memory are displayed on the screen of a display device such as a CRT or LCD.

The scroll control unit 6 determines the click state of the button based on the signal from the pointing device/button detection unit 2, and while the button is clicked, the current coordinates are determined by the output from the pointing device coordinate position conversion unit 3. Then, the scroll bar is moved via the scroll bar display section 7, and the display position of the image is controlled so that the image area designated on the scroll bar is displayed. As already mentioned, in the image data processing apparatus of the present invention, the scroll control section 6 also performs various controls when setting the display magnification, but this point will be described in detail later.

The scroll bar display section 7 moves the scroll bar according to instructions from the scroll control section 6.

It has the ability to expand and contract. In this case, in order to control the movement, expansion and contraction of the scroll bar in accordance with the movement of the pointing device operated by the operator, information on the coordinate position is obtained from the pointing device coordinate position converting section 3.

The image display section 8 displays the entire or part of the image on the image memory 11 on the frame memory 5, either at the same size or after changing the size, based on information instructed by the scroll control section 6. to draw.

The display information storage unit 9 stores the image in the frame memory 5.
This is a memory that holds information necessary for displaying images, such as image extraction position, display magnification, and other attributes.

The scaling processing unit 1o has a function of scaling the image stored in the image memory 11 at a designated scaling factor.

The image memory 11 is a memory in which images input from a scanner, facsimile, etc. are stored.

The above operations are basically the same as those of conventional image data processing devices.

As already mentioned, in the image data processing device of the present invention, the display magnification of image data is controlled by pointing the display area of the scroll bar with a pointing device or cursor while the display magnification setting mode is set. It is configured so that

In FIG. 1, the scroll control section 6 performs the following operations.

First, when the scroll control section 6 is notified from the pointing device/button detection section 2 that a button on the pointing device has been released, it performs different controls depending on the type of button.

For example, if the released button is the left button, in order to scroll the displayed image, the image display unit 8 is required to move from the new coordinate position on the image memory 11 calculated from the amount of movement of the scroll bar. Instructs to redisplay.

On the other hand, if the released button is the right button, in order to change the magnification of the image to be displayed, the expansion/contraction rate of the scroll bar is calculated from the amount of movement of the scroll bar, and the image memory 11 that is currently displayed is Image area [4th section below]
An instruction is given to the image display unit 8 to set the upper left end of ID, ) in FIG.

Through such an operation, the image on the display screen is changed to a display magnification corresponding to the amount of movement of the scroll bar.

As described above, in the first embodiment of the present invention, the left button and right button of the pointing device are used. For example, in the case of the left button, the screen scroll operation similar to the conventional one is performed, and the right In the case of a button, by performing an operation for specifying an image size, a magnification is calculated from the specified image size, and a scaling process can be performed using the magnification.

That is, as shown in FIG. 5 (1) to (3), PD
When the PD is moved while the display area of the scroll bar is indicated by the right button of the PD cursor PC, in the case of a horizontal scroll bar, the left side becomes the base point and the right side is expanded or contracted by the movement of the PD.

Then, when the PD is moved to a certain desired position and the right button of the PD is released, the display magnification is determined by the length of the scroll bar at that time.

In this case, for the horizontal scroll bar, PD
Even if you specify with P
It has already been explained that even if D is specified, the magnification processing is performed using the same magnification.

Here, regarding the image data processing apparatus of the present invention, the operations of screen scrolling using a scroll bar and changing magnification by specifying a screen size will be described with reference to a flowchart.

FIGS. 6(1) and 6(2) are flowcharts showing the main processing flow when changing the magnification by specifying the screen size in the image data processing apparatus of the present invention. In the drawings, #1 to #13 indicate steps, and ■ indicates a connection point.

Redisplay. Note that in the case of this vertical direction, the upper end is fixed.

In step #8, it is determined whether the PD button has been released (the clicked state has ended), and if it is still in the clicked state, the process returns to step #6 and repeats the same process.

If it is detected in step #8 that the PD button has been released, the process advances to step #12.

In addition, in the previous step #5, as a result of determining whether the horizontal scroll bar was clicked, if the horizontal scroll bar was not clicked (when the vertical scroll bar was clicked), step #5
Proceed to 9.

In step #9, the amount of movement of the PD is investigated, the size of the virtual scroll bar is calculated from the amount of movement, and the upper end is fixed and the virtual scroll bar is redisplayed at a new size using dotted lines.

In step #10, calculate the image magnification from the vertical scroll bar, calculate the size of the horizontal virtual scroll bar to match the magnification, and then replay the image with the new size using the dotted line. indicate. Note that in the case of this horizontal direction, the left end is fixed.

In the next step #11, it is determined whether the PD button has been released (whether the clicked state has ended), and if it is still in the clicked state, the process returns to step #9 and repeats the same process.

If it is detected in step #11 that the FD button has been released, the process proceeds to step #12.

In step #12, the vertical and horizontal virtual scroll bars are redisplayed using solid lines.

In the next step #13, the image is redisplayed using the new image magnification. In this case, the image extraction position is not changed [see FIG. 4 (1)].

By the processing of steps #1 to #13 above.

The process of changing the image magnification by operating the scroll bar by the image data processing apparatus of the present invention is completed.

In the embodiments shown in FIGS. 2 to 5 above, the case where the horizontal scroll bar is clicked with the PD has been mainly described.

However, even if I click the vertical scroll bar,
Needless to say, similar results can be obtained.

H8, VS,) is clicked to scroll the display area.

For example, by pointing the mark MU for changing the image size, that is, the mark MU added to the top end of the vertical scroll bar vS5, with the PD cursor PC, mark MU'
When moved to the position, as shown in Figure 7 (3),
The display area of the vertical and horizontal scroll bars is expanded. In this case as well, the vertical and horizontal scroll bars are expanded and contracted in conjunction with each other.

In the image shown in FIG. 7(1), the image area ID is changed to ID.

In this case, reduction processing will be performed,
G is displayed from the image area after being reduced to (MU-MD)/(MU'~MD).

The next FIG. 8 is a diagram showing a detailed example of the scroll bar and the mark for changing the image size shown in FIGS. 7(2) and (3). Reference numerals in the drawings are the same as in FIG. 7.

FIG. 8 shows details of the horizontal scroll bar.

Then, marks ML, MR (MU,
(Similarly for MD), the mark is moved in the specified direction and the image size is changed.

That is, when the mark ML is moved to the left, the image area ID in FIG. becomes narrower by that amount.

Note that if the display area of the scroll bar vS5 is designated, normal screen scrolling will be performed.

When operating the mark for changing the image size, the scroll control section 6 in FIG. 1 determines the click state of the button based on the signal from the pointing device/button detection section 2, and while the button is clicked, the scroll control section 6 in FIG. The current coordinates are checked using the 8 forces from the pointing device coordinate position conversion section 3.

If it is detected in step #31 that the PD button has been released, the process advances to step #32.

In step #32, the vertical and horizontal virtual scroll bars are redisplayed using solid lines [see FIG. 7 (3)].

In the next step #33, it is determined whether it was clicked on the left side or above the image size change mark. If the left side or the top side of the image size change mark was clicked, step #34 The process proceeds to step #35, calculates the image extraction position, and proceeds to step #35.

Further, as a result of the determination in step #33, if the clicked area is neither to the left nor to the top of the image size change mark, the process proceeds to step #35. Note that in this case, the image extraction position remains unchanged.

In step #35, the image is redisplayed using the new image magnification.

By the processing of steps #21 to #35 above.

The process of changing the image magnification by operating the image size change mark added to the scroll bar in the image data processing apparatus of the present invention is completed.

Next, still another embodiment of the image data processing apparatus of the present invention will be described. This embodiment corresponds to the invention set forth in claim 5.

This embodiment is also an extension of the first embodiment, and in the first embodiment, the extraction position of the image after changing the image size could not be changed, but according to this embodiment, , it becomes possible to change the image extraction position.

In this embodiment as well, the hardware configuration is basically the same as that in FIG. 1, and is mainly controlled by the scroll control section 6.

FIG. 10 shows an image data processing device according to the present invention.
It is a figure which shows an example of the relationship between the image image and a display screen when the image magnification is changed by operating a scroll bar, (1) shows an image image, and (2)-(4) show a display screen. In the drawing, VS6 and VS7 are vertical scroll bars,
H8 and H8 are left and right scroll bars ID, and ID are displayed image areas, and PC is a PD cursor.

As shown in FIG. 10 (2) to (4), the horizontal and vertical scroll bars are each divided into two at the center.

That is, the left and right scroll bars H8s and H8,
and a vertical scroll bar vs.

and VS are displayed.

For example, as shown in FIG. 10 (2), of the vertical scroll bars vS6 and VS7, the upper bar VSs
Click the display area with the right button of the PD and select the 10th
As shown in figure (3), move the PD and use the PD cursor PC.
When an instruction is given to expand or contract the display area of the upper bar vS6, the bar H8 on the left side of the horizontal scroll bar also expands or contracts in conjunction, so that no distortion occurs in the image.

Through such operations, the image area ID in FIG. 10(1) is changed to ID, and at the same time, the display magnification is also changed to obtain a display screen as shown in FIG. 10(4).

In addition, if you click the display area of the vertical scroll bar VS or the horizontal scroll bar H87 with the right button of the PD and perform the same operation, you can perform the same operation as shown in Figure 10 (1).
) The display magnification is changed while the lower right end of the image area ID7 is fixed.

As described above, in this embodiment, the horizontal and vertical scroll bars are each divided into two parts at the center, and when redisplaying the image after changing the image size, either the upper left edge or the lower right edge of the image is used as the base point. It becomes possible to do so.

The following FIGS. 11(1) and 11(2) are flowcharts showing the flow of the main processing when changing the magnification by specifying the screen size in the image data processing apparatus of the present invention. In the drawings, #41 to #55 indicate steps, and ■ indicates a connection point.

In step #41, it is monitored whether the PD button has been clicked.

In step #41, when the PD button is clicked, the process advances to the next step #42, and it is determined whether or not it is the scroll bar that has been clicked.

As a result of the determination in step #42, if it is not a scroll bar, the process proceeds to other functions.

If it is a scroll bar, it is determined in step #43 whether the clicked button is the right button.

As a result of the determination in step #43, if it is not the right button, the process proceeds to scroll processing.

If it is the right button, a virtual scroll bar using dotted lines is displayed superimposed on the vertical and horizontal scroll bars in step #44.

In the next step #45, it is determined whether the horizontal scroll bar is clicked.

If the horizontal scroll bar is clicked, proceed to step #46, investigate the amount of movement of the PD, calculate the size of the virtual scroll bar from the amount of movement, and set the virtual scroll bar to a new size. Redisplay using a one-dot line. In this case, the side where the PD is clicked and the sending side are fixed and do not move.

Proceed to step #47, calculate the image scaling ratio from the horizontal scroll bar, calculate the size of the vertical virtual scroll bar to match the scaling ratio, and use the dotted line at the new size. Redisplay. At this time, in the previous step #46, if the left side was clicked, the bottom edge is fixed, and if the right side was clicked, the top edge is fixed and does not move.

In step #48, it is determined whether the pressing of the PD button has ended (whether the clicked state has ended), and if it is still in the clicked state, the process returns to step #46 and repeats the same process.

When it is detected in step #48 that the pressing of the PD button has ended, the process advances to step #52.

Further, in step #45, if the horizontal scroll bar is not clicked as a result of determining whether the horizontal scroll bar is clicked (when the vertical scroll bar is clicked), step #49 , the amount of movement of the PD is investigated, the size of the virtual scroll bar is calculated from the amount of movement, and the virtual scroll bar is redisplayed at a new size using a one-dot line. In this case as well, the side where the FD is clicked and the sending side are fixed.

In step #50, calculate the image magnification ratio from the vertical scroll bar, calculate the size of the horizontal virtual scroll bar to match the magnification ratio, and then re-create the image using the dotted line at the new size. indicate. In this case, in the previous step #49, if the upper side is clicked, the right edge is fixed, and if the lower side is clicked, the left edge is fixed and not moved.

In the next step #51, it is determined whether the PD button has been pressed (the clicked state has ended), and if it is still in the clicked state, return to the previous step #49 and repeat the same process. Esu.

If it is detected in step #51 that the FD button has been released, the process proceeds to step #52.

In step #52, the vertical and horizontal virtual scroll bars are redisplayed using solid lines.

In the next step #53, it is determined whether the clicked area is on the left side or above the scroll bar.

If the left side or the upper side of the scroll bar is clicked, the process proceeds to step #54, where the image extraction position is calculated, and the process proceeds to step #55.

Further, as a result of the determination in step #53, if the clicked area is neither the left side nor the upper side of the scroll bar, the process proceeds to step #55.

Note that in this case, the image extraction position remains unchanged.

In step #55, the image is redisplayed using the new image magnification.

Through the above steps #41 to #55, the image magnification processing by operating the scroll bar in the image data processing apparatus of the present invention is completed.

Note that in the above embodiments, the display operation of the image data processing device has been described.

Therefore, the image data processing device of the present invention can be implemented not only in such a display device but also in the case of editing image data, and includes this case as well.

According to the image data processing device of the present invention, the scroll function and the function of changing the display magnification of the displayed image can be respectively assigned to two buttons of the pointing device in response to the operation of the scroll bar. It becomes possible.

Moreover, since a scroll bar is used to change the display magnification, it is possible to visually understand the display image compared to the conventional magnification changing method, and it is possible to easily set the display image size with a high degree of freedom.

For example, a system can be obtained that can easily respond to the operator's request to see further to the right.

Moreover, since the vertical and horizontal directions are expanded and contracted in conjunction with each other, distortion does not occur in the image after the scaling process (effect corresponding to the invention of claims 1 to 3).
.

Also, by adding a mark to the scroll bar to change the display magnification and distinguishing the display area of the scroll bar, you can use the same button.

It is possible to scroll and change the display magnification of the displayed image, and also to change the image extraction position (effect corresponding to the invention of claim 4).

Furthermore, by dividing the display area of the scroll bar into left and right or top and bottom, it is possible to use the display area when changing the display image size as the base point at either the upper left or lower right edge. Many excellent effects can be obtained, such as a system that can easily meet the demands of those who want to see the image (an effect corresponding to the invention of claim 5). .
