Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) [0001] The present invention relates to an image creating apparatus for creating a new image by synthesizing and editing a plurality of images.

(Prior art) Conventionally, in various presentations such as paper presentations at academic conferences and lectures, the presenter appeals to the sight and hearing of the listener using an OHP slide projector, etc. It aims to improve communication and effectively promote presentations.

These are slide films prepared by the presenter in advance or OHP films projected on the screen. However, these require a great deal of labor and cost when making the film, and thus impose a heavy burden on the presenter.

Also, in recent years, an image creating apparatus for presentations using a computer has become popular. This is because an image input device such as an image scanner or a computer is used to create an image by using a screen editor of the computer. The created figures or characters are combined and edited to create a presentation material. However, in these image creating apparatuses, when a plurality of images are combined, modified, and edited to create a new image, when a part of the combined image is deleted or moved, the entire image is corrected. There is a method of re-editing from the beginning. However, this method is inefficient and requires a long processing time because it is necessary to reprocess the entire image or perform processing from the beginning.

(Problems to be Solved by the Invention) As described above, in the conventional apparatus, even when a part of the combined image is edited, it is necessary to reprocess the entire image, which is inefficient.

Therefore, it is an object of the present invention to perform, at the time of editing an image obtained by synthesizing and editing a plurality of images, the processing required for editing the image by the change at high speed and efficiently without causing the above-mentioned inconvenience. The object is to provide an image creation device that can do this.

[Structure of Invention]

(Means for Solving the Problems) The present invention divides an image into a plurality of blocks and creates a history table for each block in an image creating apparatus that synthesizes and edits a plurality of images to obtain a new image. In addition, the editing process of composition / correction is performed.

(Operation) According to the present invention, since the area to be combined and edited is divided into blocks and the editing is executed by the history table prepared for each block, only the area of the block that needs to be corrected is processed to correct the image and update the history table. I'm trying to do.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a schematic configuration of the apparatus of the embodiment. In the figure, an image to be combined and edited is input from an image input unit 11 such as an image scanner and stored in an image storage unit 12. The images stored in the image storage unit 12 are edited by the editing processing unit 13
The composite edited image is edited and stored in the image storage unit 12 again as a new image. This composition / correction is displayed
It is performed while the user sees 14. The further edited image is output as a hard copy by the image output unit 15.

FIG. 2 is a diagram for explaining composition and modification of a plurality of images. Here, the image 21 in FIG. 9A is a basic image to be combined and modified. Images of (b) and (c) in FIG.
22 and 23 are images to be combined and edited with the image 21, an image 24 in FIG. 7D is an image in the middle of editing, and an image 25 in FIG. 8E is a final edited image.

FIG. 3 is a diagram showing how the screen is divided. In the embodiment, description will be made assuming that the screen is divided into 16. Each block is numbered 1-16.

FIG. 4 is a history table for keeping the edit process of combining and correcting in block units as a history.

It is assumed that images to be combined and edited are stored in advance in the image storage unit 12 in FIG. The image read from the image storage unit 12 enters the edit processing unit 13 and is displayed on the display unit 14. The image read out first is the basic image before being edited. Here, the image 21 in FIG.
And At this time, the history table of FIG. 4 is set to 1 for all blocks as indicated by P1. Next, in the images 22 and 23, the partial areas 26, 27, and 28 surrounded by the dotted lines are combined with the image 21, and if the image 24 is obtained, the history table is composed by combining the partial areas 26 as shown in P2. The changed block numbers 12, 1415, 16 are set to 2, and the previous state of 1 remains unchanged for the unchanged block. Similarly, in the composition of the partial area 27, the history table P3 has three block symbols 6, 9, 10, 14
In the composition of the partial area 28, the block number 1 is set to 4 in the history table P4. As described above, the history table is created by combining. Next, how the contents of the history table are changed when the combined partial area 27 is deleted from the combined image 24 will be described. The blocks changed in the department area 27 are 4 of 6,9,10,14 set to 3.
Since it is a block, the table is reversely climbed until the setting value 3 changes to another setting value, and when a change is detected, a process of replacing with a block of the image corresponding to the setting value at that time is performed. For example, since the set value in block 6 of the history table P4 is 3, the set value changes to 1 in P3, P2 and reverse climb P2, so block 6 of image 24 is replaced with the image of block 6 of image 21. Similarly, the 24 blocks 9 and 10 of the image
21 blocks 9 and 10 are replaced by blocks 14 of image 24 by blocks 14 of image 22 to obtain a modified image 25.

In the replacement process described above, the set value is also rewritten at the same time to create a new history table P5.

The final image 25 edited in this manner is stored in the image storage section of FIG. 1 and is also output to the image output section 15 to obtain a hard copy.

The present invention is not limited to the above embodiment. For example, the number of divided blocks has been described as 16 in the embodiment, but the number of divided blocks may be determined according to the fineness of the graphic character or the like to be combined and edited.

〔The invention's effect〕

As described above, according to the present invention, the image is divided into a plurality of blocks, a composite editing history table is prepared for each block, and processing is performed on a block-by-block basis when the correction is made. It becomes possible to execute the editing process at high speed and efficiently.
