JPS6126178A - Processing method of large picture - Google Patents

Abstract

PURPOSE:To obtain a large picture processing method having high operability by processing a large picture in the same processing procedure as that of a picture processing instruction to a partial picture stored in a processing history file when the processing of a large picture is required. CONSTITUTION:A partial picture 9 is separated from a large picture 8 by processing 16 and displayed on a display as a partial picture 10. A series of processing 17 of the partial picture 10 is executed to obtain a picture 11. The user may consider that the original picture 8 is processed by the same processing as that of the partial picture 10 and the whole picture 12 against the partial picture 11 is formed as shown in an arrow 18. Actually, the processing 11 is applied only to the partial picture and the processing speed of the processing 11 executed like trial and error is not delayed. If another area 14 in the virtual large picture 12 is required, the processing procedure obtaining the partial picture 11 from the partial picture 10 is extracted from the processing history file to obtain a processed partial picture 15 from the partial picture 14. Similarly, the whole picture is stored in a picture file.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an image processing device, and particularly to improving the operability of image processing commands and processing when performing image processing interactively on large images. The present invention relates to an image processing method suitable for reducing time.

[Background of the invention]

In the field of image processing, processing is often carried out interactively. That is, a certain process is performed on a certain image, the result is displayed on an image display device, and a human evaluates it to determine whether to proceed with the process or restart the process. Therefore, in image processing apparatuses, improving the operability of nine image processing commands and shortening processing time plays a major role in improving work efficiency.

However, with general image processing devices, the image size that can be displayed ranges from 256 x 256 pixels to as large as 1024 pixels.
It has 1024 x 1024 pixels, and cannot display large images of several thousand x several thousand pixels, which are handled in satellite image processing or medical image processing.

Therefore, in the conventional method, once the desired result is obtained by interactively performing image processing on a partial image cut out from a large image, processing is performed on the original large image again according to the processing steps that led to that result. I had to.

With this method, the user must record the processing steps for the partial images one by one, and the image processing commands performed on the partial images must be executed again on the large image, resulting in poor operability. The disadvantage was that it decreased.

[Purpose of the invention]

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a large-scale image processing system with excellent operability.

[Summary of the invention]

In the method of the present invention, image processing commands performed on cut out partial images are stored in a processing history file. If the results of processing the original large image are required, the processing history file is referred to and the results are obtained by automatically processing the large image according to the same processing procedure as that for the partial images.

According to this method, the user can proceed with processing on a partial image as if it were being performed on the entire large image.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows the flow of processing and the flow of image data. It is assumed that the large image to be processed is stored in image file 1.

First, in image processing for large images, processing step 4
The partial image data is cut out, stored in a storage device 2 (hereinafter referred to as "display memory J") for display on an image display device, and displayed.

The command of processing step 4 is stored in the processing history file 7, and it is managed which area of the original large image the partial image being displayed corresponds to. In processing step 5, various image processes are repeatedly performed on the partial images stored in the display memory 2 in a trial and error manner until a desired result is obtained. The image processing command executed at this time is stored in the processing history file 7.

After completing the processing on the partial image, in processing step 6, a process is performed in which another area is cut out to confirm the processing results on other parts of the large image, or the entire processing result is stored in the image file 3. At this time, since no processing has been performed on the original large image except for the partial image area stored in the display memory 2, when processing step 6 is executed, the processing procedure performed on the partial image is It is necessary to read out the image data from the processing history file 7 and apply it to the original large image to create the image data necessary for processing step 6.

At this time, the processing history file 7 is sequentially read out from the latest one, and the steps until the resulting partial image is created are followed in reverse order. Therefore, processes unrelated to the final result are not performed through trial and error, and the necessary image data is automatically generated in the shortest procedure.

FIG. 2 shows the processing procedure from the user's perspective. In process 16, a partial image 9 is cut out from the large image 8 and displayed as a partial image 10 on the display. A series of processes 17 are performed on the image 10 to obtain the resulting image 11. At this time, for the user, the processing on the partial image 10 is the original large image 8.
It can be considered that the entire image 12 for the partial image 11 is generated as shown by the arrow 18. In other words, all processing is performed on the entire image, and the user can view the partial image 13 from the display.
You can think of it as monitoring.

Here, in reality, processing 11 is performed only on partial images, and the processing speed of processing 11, which is performed by trial and error, does not slow down. Next, when another area 14 of [virtual large image ]-2 is required, the processing procedure for obtaining the partial image 11 from the group partial image 10 is extracted from the processing history file,
A partial image 15 as a processing result is obtained from the partial image 14. (Process 19) The same applies when storing the entire image in an image file.

As described above, according to this embodiment, when processing a large image interactively, it is possible to improve the operability without impairing the processing speed.

〔Effect of the invention〕

According to the present invention, it is possible to proceed with image processing while considering that the processing on the displayed partial image is being performed on the entire large image, which has the effect of improving the operability of the image processing device. .
