Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing method and apparatus for editing and laying out image data.

[0002]

2. Description of the Related Art In a conventional image editing method, image data input from an image input device such as a scanner or image data stored in a storage device such as a hard disk is edited by an image editing unit such as a CPU. It was to add processing such as layout and save the final processed image data in a storage device or send it to an output device for printing.

[0003]

However, in the above-mentioned conventional image editing method, the amount of individual image data also increases with the improvement of the reading accuracy of the input device and the quality of colorized images. As a result, the amount of edit result image data processed by adding edit processing such as editing and layout becomes very large, and it takes time to save the processed edit result image data in the storage device. In addition, there is a problem that a large storage area is required.

Further, the conventional image editing method has a problem that when a part of the original image data is changed, it is necessary to edit and layout the image data again.

The present invention solves the above-mentioned conventional problems, enables a large reduction in the storage area, and allows the same editing to be performed for a change in the original image without performing a new editing operation. It is an object of the present invention to provide an image editing method and a device therefor capable of obtaining a result image.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention does not directly modify an original image when editing the image in accordance with an input image editing command. Edit the temporary image created by duplicating the image and record it while optimizing the sequence of image editing commands up to the final editing result, and from the recorded image editing command and the original image, the final result The image is reproduced.

[0007]

According to the present invention, with the above configuration, since the original image and the editing history for the original image are recorded without recording both the edited image and the original image, the storage area can be significantly reduced. Further, it is possible to obtain the same edited result image even if the editing operation is not performed again for the change of the original image.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of an image editing apparatus according to an embodiment of the present invention. In FIG. 1, 1
01 is an image memory for editing for storing images for editing, 10
Reference numeral 2 is a command input means such as a keyboard or mouse, 103 is an instruction input by the instruction input means 102, and the instruction is an image edit instruction for editing the image data, or the edited result image data is reproduced. Command selecting means for selecting whether it is an image reproduction command, 104 is an image editing means for performing an editing operation on image data by an image editing command from the command selecting means 103 or an image editing command from an edited result image reproducing means which will be described later. , 105 are original image storage means such as a hard disk or a CD-ROM. Reference numeral 106 denotes an edit instruction storage means for storing the image edit instruction executed by the image edit means 104. At the time of storing, the instruction already stored in the edit instruction storage portion 108 is examined and an attempt is made to store the instruction. If there is an image edit command and a degenerate one, the image edit command and the degenerate process are performed, and then the image is stored. 107 is an instruction selecting means 103
When the image reproduction command is received from the edit result image reproduction unit, the image edit command for reproducing the edited result image is extracted from the edit command storage unit 108, and the image edit command is input to the image editing unit 104. Reference numeral 108 denotes an edit command storage unit that stores an image edit command, and 109 is an image display unit that displays an image on the screen.

An outline of the operation of the image editing apparatus having the above configuration will be described below with reference to the flow chart shown in FIG. However, before the actual editing operation is performed, the image editing means 104 reads the original image required for editing from the original image storage means 105 and stores it in the editing image memory 101, and this state is set as the initial state. Various editing / layout operations.

First, in step 201, the command input means 102
The command input by the command input means 102 in step 202 is executed by the command selection means 103.
If it is an image editing command that analyzes the image data and edits the image data, go to step 203. If it is an image reproducing command that reproduces the edited result image data, go to step 2
The process proceeds to 06. The image editing instruction is, for example, an affine transformation instruction such as image enlargement / reduction and rotation, a filtering instruction such as color conversion, edge extraction, and emphasis, and an original image is read from the original image storage unit 105 and transferred to the editing image memory. There is a transfer command to do so.

From step 203 to step 205,
Processing is performed when the command selected in step 202 is an image editing command. In this step, the image editing unit 104 causes the editing memory 101 to follow the image editing command.
Edit processing is performed on the image inside. First step 20
The image editing command used in the editing process performed in step 203 in step 4 is degenerated by the editing command storage unit 106 to one of the past image editing commands stored in the editing command storage unit 108, and the image editing command is deleted. Optimization is performed. Next, in step 205, the image editing instruction degenerated in step 204 is stored in the editing instruction storage unit 108.

From step 206 to step 208,
Processing is performed when the command selected in step 202 is an image reproduction command. First, in step 206, the edited result image reproduction means 107 that has received the image reproduction command retrieves the image editing command from the editing command storage unit 108. Next, in step 207, the original image is extracted. The edited result image reproducing unit 107 inputs to the image editing unit 104 a transfer command of the original image included in the image editing command extracted in step 206. Upon receiving this command, the image editing means 104 retrieves the original image from the original image storage means 105 and stores the image in the editing image memory 101.
Transfer to. As a result, the initial state is reproduced. Then, in step 208, the edited state is reproduced.
The editing result image reproducing means 107 inputs the image editing command fetched in step 206 to the image editing means 104.
Upon receipt of the command, the image editing means 104 sequentially edits the original image extracted in step 207 in accordance with the image editing command to reproduce the edited image.
