DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dot image klWfi method using a computer capable of editing images.

[Conventional technology]

In general, image editing is performed using a computer that can edit images, but in conventional image editing, the screen that is subject to manual input by the operator is only an overall image or an enlarged image. There were only a few different types, or a combination of them. Therefore, the operator uses a predetermined screen regardless of his or her will.
Coordinates are specified by scrolling the screen.

[Problems to be solved by the invention]

However, with such conventional editing methods, for example, when editing an enlarged image, if the image consists of a large number of pixels, it may become impossible to grasp the entire image, or it may take too many pixels to display the desired range. A scroll operation has to be performed, which takes time,
On the other hand, if you lower the magnification so that you can see the whole picture,
As the area of the specified dot becomes smaller, the user must be more careful in determining the coordinates, which increases the degree of fatigue, and when editing the dot image, there is a problem that it is not possible to grasp the overall image and specify the dot unit at the same time. there were.

The present invention is intended to solve the above-mentioned problems.It is possible to set any range specified by the operator to be displayed on the editing screen at any magnification ratio, and it is possible to edit details while always grasping the overall image. The purpose is to provide a method for editing dot images.

[Means for solving problems]

To this end, the dot image editing method of the present invention includes a magnification rate change/setting section that specifies the magnification rate change mode and sets the magnification rate, and a magnification range specification and dot image data input, A position determining unit that determines the position coordinates of image data, a magnification rate changing/setting unit, a control device into which output data from the position determining unit is input, and an image memory that is controlled by the control device and stores dot image data. , is equipped with a display drive section that is driven and controlled by a control device, and a display section that has an editing screen, an overall image display screen, and an auxiliary screen. The present invention is characterized in that the overall image is displayed on the display screen, and the positional relationship of the editing screen with respect to the overall image is displayed on the auxiliary screen to edit the dot image.

[Effect]

In the dot image editing method according to the present invention, the entire image is displayed on the overall image display screen, and the positional relationship of the editing screen with respect to the entire image is displayed on the auxiliary screen, so that editing can be performed to enlarge an arbitrary range at an arbitrary enlargement rate. By inputting dot image data on the screen, it is possible to edit details while always understanding the overall image.

When the output data from the magnification rate changing/setting section 1 is transferred to the control device 4, the control device 4 controls the display driving section 6.
, an inverted display is displayed on the CRT screen for selecting an enlarged range, which will be described later.

The position determination unit 2 calculates and determines the position coordinates of the specified enlarged range, and transfers the results to the control device 4.

The control device 4 receives this data, reads out the specified range of data from the image memory 5, and displays it at the specified enlargement rate.
Display on RT screen. In addition, the position determining unit 2
The position coordinates of each dot whose position is selected by the data input section 3 and inputted with ON or OFF image data are calculated and determined and transferred to the control device 4. The control device 4 writes the transferred data into the image memory 5 and displays it on the CRT screen. In addition, the CRT screen includes an editing screen, as described later.
An overall image display screen and an auxiliary screen are displayed, and the dot images are edited by enlarging the details while always grasping the overall image of the object to be edited.

Next, the dot image editing method of the present invention will be explained with reference to FIGS. 2, 3, and 4.
