Abstract

PURPOSE:To stepwise and partially restore an original picture in color mixing processing by providing a picture calculating part to picture-calculate data in an original picture storing memory and data in a color mixing processing picture memory when the picture is displayed and a picture processing parameter setting part to set various parameters for picture processing. CONSTITUTION:The color mixing processing is executed by using a picture memory 10 which is different from a memory 5 in which the original picture is inputted. Further, while the respective contents of the memory 5 in which the original picture is inputted and the picture memory 10 for which the color mixing processing is executed are picture-calculated, the respective contents are displayed. Consequently, an effect equal to that obtained when the color mixing processing is directly executed for the original picture can be obtained. Further, when the original picture is restored, color mixing processing with '0' designated picture element is executed for the picture memory 10 for which the color mixing processing is executed by using the above-mentioned technique. Thus, the original picture can be restored stepwise.

[Industrial application field]

The present invention relates to a color mixing processing device used in a veining system, and more specifically, the present invention relates to a color mixing processing device used in a veining system, and more specifically, when mixing a specified color in a specified area of a color image that has already been displayed, a partial original image is mixed in stages. The present invention relates to a color mixing processing device that allows easy restoration and reduces the burden on the operator.

[Conventional technology]

The previously used veining system.

Display digital image data input into an image input device such as a color scanner on a color display, and display it using a computer device such as a mouse or tablet.
It is a system that allows you to edit and process colors and images interactively.

In such a system, if there is a defective part in the processing result of an image subjected to two-color mixing processing, there is a need for an apparatus that can gradually restore the part to the original image.

However, as a conventional technique for performing the above processing,
An original image restoration method as shown in FIG. 5 was used.

In this method, 2 For example, if there is a defective part D (image inside the dotted line) in a part of the image Pl that is undergoing 9-color mixing processing, the original image P2 that has been saved in advance is converted into an image for 2-color mixing processing. By copying, the image P3 in its initial state (substantially Pz=P3) is restored without being subjected to the -cut color mixing process.

This method has been used due to memory limitations, processing time limitations, and the like.

After all, if a large amount of memory is used to store image data from all processes during the two-color mixing process, it is possible to restore the image from any process; Also, it would be impractical due to the memory requirements. If you do the above, you will end up transferring a lot of 2 image data.

This is also not possible because the time required for transfer increases and the time required for color mixing processing as a whole becomes enormous.

Therefore, conventionally, as shown in FIG.

- A method was used to restore the initial state without any mixing processing.

(Problems to be Solved by the Invention) The conventional devices as described above had the following drawbacks.

In other words, even if there are deficiencies in the color mixing process that was performed immediately before, and there are no deficiencies in the previous color mixing process, the original image will be restored to its initial state without any mixing process. To get rid of it.

It is necessary to repeat the color mixing process that has been performed up to that point.

For this reason, there is a drawback that the burden on the operator is large and the time required for processing is also large.

The present invention solves these conventional drawbacks and allows partial restoration of the original image in two-color mixing processing to be performed step by step and interactively, thereby reducing the burden on the operator and reducing processing time. The purpose is to shorten it.

[Means to solve the problem]

In order to achieve the above object, one aspect of the present invention is as follows.

FIG. 1 is a diagram showing the principle of a color mixing processing device according to the present invention.

The main control department engineer who controls the entire device initializes the contents of the image memory 10 for nine-color mixing processing and performs rOJK.
The contents of the original image storage memory 5 are transferred to the display unit 12 and displayed.

To perform color mixing processing 9 Image processing parameter setting section 13
This is done by specifying the processing area of the image memory 10 for color mixing processing and setting the pixel value and weighting coefficient.

Next, to restore the image that has been subjected to one-color mixing processing step by step to the original image, specify the processing area of the image memory 10 for color mixing processing in the two-image processing parameter setting section 13, and set the specified pixel to "0".
Then, the two-color mixing processing section 9 performs color mixing processing using 92 weighting coefficients.

After this color mixing process is completed, the contents of the image memory 10 for two-color mixing process and the contents of the original image storage memory 5 are subjected to image calculation in the image calculation unit 8 and displayed on the display unit 12. [Operation] As described above. With this configuration, color mixing processing is performed using an image memory separate from the memory containing the original image, and the contents of the memory containing the original image and the image memory subjected to two-color mixing processing are displayed while performing image calculations. In particular, an effect equivalent to that obtained when color mixing processing is directly applied to the original image can be obtained.

In addition, by using the above method, when restoring the original image, the original image can be restored in two stages by simply performing color mixing processing for the specified pixel rOJ on the image memory that has undergone the two-color mixing processing. can be restored.

Thereafter, when the control unit 1 is notified of the color mixing process from the process specifying unit 4, the area specifying unit 2 specifies the processing area of the image memory 10 for color mixing processing, and the color specified by the nine color specifying unit 3 is used. The one-color mixing processing circuit 9 uses the corresponding pixel value as the specified pixel value.
Color mixing processing is performed using the weighting coefficient memory 6 and the weighting coefficient memory 6.

Further, when the processing specifying unit 4 notifies the original image restoration process, the area specifying unit 2 specifies the processing area of the image memory 10 for color mixing processing, sets the specified pixel value to “0”, and the 9-color mixing process unit 9 Color mixing processing is performed using the weighting coefficient memory 6 and the weighting coefficient memory 6.

After the color mixing process is completed, the main control unit 1 performs image calculation on the contents of the image memory 10 for two-color mixing process and the contents of the original image storage memory 5 in the image calculation unit 8, and directly frames the result data. By transferring the data to the memory 11, the one-color mixing processing results are displayed.

After the operator specifies termination, the main control unit 1 saves the contents of the image memory 10 for two-color mixing processing and the memory 5 for storing the original image.
The content of the image calculation unit 8 performs image calculation, and the result data is stored in the processing result storage memory 7.

In the above configuration, the two-color mixing processing unit 92 and the image calculation unit 8 are usually configured by electronic circuits, but other software-based configurations may be used.
