Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an image data processing method, and in particular, to a method for extracting data when editing a read image with a large amount of data that cannot be displayed entirely on a screen. The present invention relates to an image data processing method in which a screen is displayed on the screen, image editing is performed on the screen, and the results are reflected in the original data.

[Conventional technology]

Conventionally, when reading image data using a scanner, for example, as shown in FIG.
Unnecessary pixels other than those in the "regular image area" may be read.

[Problem to be solved by the invention] In such cases, it is necessary to edit the read data, but in the past, in such cases, unnecessary pixels outside the regular image area were sequentially processed while scrolling the screen. I had to do it, and I had to spend a lot of time and effort.

Note that, as an example of such a data processing device, for example,
A device disclosed in Japanese Patent Publication No. 62-46899 is known. This device specifies an unnecessary image (dirty part) of a certain size by hitting a point inside it, and then stores it in the storage unit.

A table of contour coordinates of a dirty area is created, all points included in the table are automatically picked up, and the corresponding data in the storage section is sequentially erased from a certain direction.

However, even in this device, when there are a plurality of (discretely) soiled parts as described above, a hit is required for each of them, and there is a problem similar to the above case.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to solve the above-mentioned problems in the conventional technology and to reduce the processing time and time suitable for editing read images containing a large number of unnecessary pixels. An object of the present invention is to provide an image data processing method that can reduce labor and effort.

[Means for Solving the Problems J The above object of the present invention is to provide an input section for inputting various instruction operations, a reading section for reading an image, a display section for the read image, and a display section for displaying the read image and performing image editing. In an image human-powered system that has an image editing section, when editing a read image, if the amount of data in the read image is large and it is not possible to display all of the data on one screen, the data is extracted and displayed on the screen, and the screen is This is achieved by an image data processing method characterized by reflecting the result of removing unnecessary pixels in the original data.

[Function] In the image data processing method according to the present invention, when the amount of data in a read image is large and all of the data cannot be displayed on one screen, data can be extracted within the necessary range (hereinafter referred to as "suppression"). The entire image can be displayed on the screen, and the image can be edited on this screen, and the editing results can be reflected in the original data, reducing processing time and effort. This implements an image data processing method.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of an image input device showing an embodiment of the present invention. In FIG. A display control section that controls the CRT display 6, 5 a storage section (memory), and 7 a processor.

FIG. 1 is a flowchart showing the operation of this embodiment, and FIG. 3 is a diagram showing an example of a read image. below,
The operation of the embodiment will be explained based on FIGS. 1 and 3. Note that here, a case will be described as an example in which a portion inside or outside of a range defined by a rectangle on a display image is deleted.

First, in step 11, an original drawing is read from the scanner 2. Next, in step 12, the read image data is suppressed. Here, as a method for suppressing image data, as shown in Fig. 3, there is a method of converting an original image (a) consisting of 2000 pixels x 000 pixels into a screen display (b) of 1000 pixels x 500 pixels. Use.

Specifically, as shown in FIG. 4(a), this means that the horizontal data is l /2.1 /2. . . . and a method of extracting data in the horizontal direction at a thinning rate in the vertical direction as shown in (b).

Next, in step 13, the suppressed data is displayed on the screen, and in step 14, it is specified whether the image to be deleted is inside or outside the range defined by the aforementioned rectangle. After this specification, in step 15, the above-mentioned rectangle is set by specifying two points, and after confirmation (step 16), if it is OK, the process is executed in step 17.

In step 18, the processing result is displayed on the screen (see FIG. 3(d)), so it is determined whether the result is satisfactory, and if there is still room for improvement, the process proceeds to step 20. The entire process is redone, and if the result displayed in step 18 is satisfactory, the process proceeds to step 21, where actual data corresponding to this result is calculated and registered as input data. Here, the actual data to be registered is as shown in FIG. 3(C).

According to the above embodiment, in the image input system, when editing a read image, the amount of data of the read image is large;
Even if all the data cannot be displayed on one screen, the data will be extracted as appropriate and displayed on the screen, and the results of editing such as deleting unnecessary pixels on this screen will be reflected in the original data. Therefore, an image data processing method suitable for editing a read image containing a large number of unnecessary pixels can be realized, which has a great effect on reducing the operation time and effort of the operator.

FIG. 5 shows the functional configuration of the data processing section 3 in the above embodiment and the corresponding operation. A detailed explanation of the operation will be omitted since it overlaps with the explanation of FIG. After processing by the processing function 32,
If necessary, data is suppressed, and the suppressed data display function 33 displays the result on the CRT display 6.

Next, the processing range specification function 34 converts the cursor position input as a display on the CRT display 6 and the cursor position on the actual data, and converts the density information "1" in the specified processing target area. By setting it to "0", the processing execution function 35 is activated. Finally, the processing of the above-described embodiment is realized by operating the actual data processing function 36 that converts the processing results edited on the CRT display 6 into processing on actual data.

In the above embodiment, when deleting a displayed image, the range is specified as inside or outside a rectangle by specifying two points, but this is not possible using other methods. But it's okay. For example, a method of specifying whether it is inside or outside of an arbitrary dirt shape formed by specifying three or more points, or a method of specifying whether it is above or below a polygonal line connecting multiple points, etc. , various methods can be used.

It should be noted that the above-mentioned embodiment merely shows an example of the present invention, and it goes without saying that the present invention should not be limited thereto.

r Effects of the Invention] As described above in detail, according to the present invention, there is an input section for inputting various instruction operations, a reading section for reading one image, a display section for displaying the read image, and an image display section for displaying the read image. In an image input system having an image editing section that performs editing, when editing a read image, if the amount of data in the read image is too large to display all of the data on one screen, the data is extracted and displayed on the screen, By reflecting the result of deleting unnecessary pixels on the screen in the original data, it is possible to reduce processing time and effort, which is suitable for editing read images containing a large number of unnecessary pixels. This has the remarkable effect of realizing a possible image data processing method.
