Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image editing method, and more particularly to an image editing method that improves operability when scrolling images displayed on a display means.

(Prior Art) An image editing device displays an image on a display means (for example, a CRT), and operates the displayed image using a position indicating means while observing the displayed image, performs various image processing, and outputs the results. The information is recorded on paper using an output means such as a printer. In the process of image editing using this type of device, there are cases where it is desired to scroll (move) the image displayed on the display screen vertically and horizontally.

For example, if you want to scroll the screen upward, the conventional method is to move the cursor to the bottom position and continue to press the operation key until the screen reaches the desired state. Alternatively, you can prepare a scroll command as a command, display a mark on the screen to scroll up and down by 1/6 screen, move the cursor there and press the key manually, or use the keyboard. A method of providing a scroll command generating key and pressing that key to scroll is also used.

(Problem to be Solved by the Invention) In the case of conventional scrolling methods, the amount of scrolling per time is determined in advance, so in order to scroll the image to the desired position, it is necessary to scroll the image multiple times. Key human resources are required. Additionally, since the scrolling direction is limited to the up/down or left/right directions, if you try to scroll diagonally, you have to scroll up/down and scroll left/right separately, which reduces operability. was extremely bad.

The present invention has been made in view of these points, and
The purpose is to provide an image editing method with improved operability during scrolling.

(Means for Solving the Problems) The present invention, which solves the above-mentioned problems, displays l! on the display means.
iIl! When editing an image by displaying an image, step [1]) instructs a specific position of the target image using a position specifying means, and moves the image specified by the position specifying means to a predetermined position on the display means. It is characterized in that it is moved (step [2]).

(Function) The destination position of the image is stored in advance, and the image is quickly scrolled to the target position with a single key operation by simply specifying the target image.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Figure 1 is a flowchart showing the basic raccoon method of the present invention;
The figure is a system configuration diagram for implementing the method of the present invention. In FIG. 2, 1 is an input device for inputting images, 2 is a processing device for editing the images inputted by the input device 1, and 3 is a display device for displaying images when collecting food.

For example, a COD is used as the input device B1, a microprocessor is used as the processing device 2, and a CRT is used as the display device 3, for example.

4 is a processing device 2 for processing various information (commands, parameters, etc.)
5 is a position indicating means for inputting position information of a figure; 6 is a memory 8 for storing image information; and 7 is an output device for outputting an image based on an image editing method.

As the position indicating means 5, for example, a digitizer is used, as the storage device 6, for example, a magnetic disk device is used, and as the output device 7, for example, a dot printer is used. The method of the present invention will be explained using a system configured as described above.

Image information enters the processing device 2 by being input through the input device 1, by commands from the keyboard 4, by inputting parameters, or by drawing by the position indicating means 5. This image information is displayed on the display device 13. The operator edits the image information using the keyboard 4 and position indicating means 5 while viewing the image information such as characters and graphics displayed on the display device 3. The completed image is then output by the output device 7. For example, it is printed and recorded on paper.

When outputting an image to an external device, in order to obtain a high-quality output, it is necessary to make the size of one pixel of image information to be processed extremely small. For example, it is necessary that the size of one pixel is at least about 1/16 mm.

Input an image with this level of resolution! iii, processing by the processing device 2, and outputting by the output device 7,
This has become possible due to the development of storage elements such as RAM and laser technology for outputting images from lTi image input elements such as COD.

However, the display device 3 is generally a CRT.
is used, but its resolution is at most 1/4
1111&! It is impossible to display all of the information at the same size as the output image. For example, A4 size image information that is processed with a resolution of 1/16ml is 1/411Ill.
In order to display on an A4 size CRT with a resolution of must be enlarged or displayed.

Here, rough editing work can be done while viewing the thinned out original size information, but when editing detailed parts,
You will inevitably have to edit while viewing some of the enlarged information. FIG. 3(b) shows the image not shown in (a) displayed at the same size, and FIG. 3(c) shows a part of the image shown in (b) enlarged. Here, if the operator wants to edit the 118 I+ part of the image shown in (c), the operator scrolls the display screen and selects "
It is reasonable to bring "B" to the center of the screen and then edit it.

In the conventional method, it is necessary to position the cursor 10 at the right edge of the screen as shown in (b) and keep pressing the operation key until 11 B II comes to the center of the screen.

“Once B II is in the center of the screen, move cursor 10 to the top of the screen as shown in (c), move “B” downward, and 1B” will also be in the center of the screen in the downward direction. The operation key must be held down until

In the present invention, the position on the screen to be placed is memorized in advance, and as shown in FIG. Bring up the cursor 10 and press the operation key only once. As a result, the processing device 2 starts the scrolling process and brings the image "B" to a predetermined position a (here, the center of the screen) as shown in (b). In other words, a processing device! 12 performs vertical scrolling and horizontal scrolling at the same time,
Move the image to the desired position with a single key operation.

This greatly improves the operability of image editing.

Here, if the cursor 10 is moved using a digitizer using absolute coordinate input, the cursor 10 will remain at its original location as shown in (b). In the case of a mouse, since it is a relative movement input, the position of the cursor 10 can be set freely, and can be moved together with the image "B" as shown in (c).

According to the present invention, as shown in FIG. 6(a), the cursor 1
After indicating 0 at the top of the screen, press the operation key (B)
As shown in the figure, the area outside the information area (the shaded area) may be displayed. This is not a problem in itself, but it becomes easier to see if some pattern or color is applied outside the area.

Furthermore, as shown in (c), the area outside the area can be made not to be displayed. The image after the editing process is stored in the storage device M6. The stored 1tlii image information can be read and edited at any time.

The operations described above are realized in the system shown in FIG. 2 as follows. Image or position indicating means 5 inputted by input device H1. The image drawn using the keyboard 4 is
Processing equipment! 2 and stored in an image memory (not shown) within the processing device 2.

Then, the display data written in the bitmap display memory (not shown) is transferred to the display device 3 by DMA transfer.
will be forwarded to and displayed. Therefore, by writing data in the image memory to the display memory, image data at an arbitrary position can be displayed.

Therefore, as shown in FIG. 7, the position of the point indicated by the position indicating means 5 on the image memory 21 is set to (a, b) as shown in FIG. 8 (a), and the display magnification is set to 01.
The height of the table display memory 22 is as shown in FIG.
XI. Here, if we hold the point (a, b) at the center of the display, then (a-(l!/2n), b-(s+/2n)) and (a + (l!/2n)) and (a + (l!/2n)) on the image memory 21 !/2n),
b-)-(m/2n))
The data within the rectangle formed by is enlarged or reduced by the enlargement/reduction circuit 23 according to the magnification n, and is transferred to the display memory 22. The contents of the display memory 22 are sent to the video A converter 24, converted to a video signal, and displayed on the display fl (CRT>3 in this case.The coordinates of the points shown here are the logical PI! coordinates. Yes, and the correspondence with the main address on the actual hardware differs depending on each hardware configuration.Also, the display magnification n is n when one pixel on the image memory 21 corresponds to N pixels on the display memory 22. -an'r.

In the above description, the case where the image is brought to the center of the screen by scrolling has been explained as an example.

However, the present invention is not limited to this, and may be placed anywhere on the screen as long as it is a predetermined specific position.

(Effects of the Invention) As described above in detail, according to the present invention, the movement position of an image is determined in advance, and the target image is automatically moved to the movement position simply by specifying the target image using the position indicating means. Since it can be moved, the operability during scrolling is greatly improved compared to the conventional method.
