Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image editing device, and in particular, it is possible to easily specify an editing range for an input manuscript, and to easily understand editing contents such as movement. The present invention relates to an image editing device.

[Prior art]

Conventionally, copying machines have been used to perform editing operations such as moving and deleting. Such editing is usually done by specifying the editing range, but conventionally the editing range has been specified by inputting the coordinate position using a tablet, etc., or by directly marking the original with a marker etc. There is a way to specify a range.

In addition, as another related technique, there is an image input device that performs image editing by superimposing an additional image input from a transparent tablet on a read image of a document (Japanese Patent Application Laid-Open No. 60205623).

[Problems to be Solved by the Invention] Editing using a tablet as described above has the drawback that the editing work is complicated because coordinate positions must be input, and furthermore, it is difficult to visually confirm the editing work. Ta.

In addition, although the specification method using markers makes it easy to check the editing work, it only allows simple editing such as deletion, and if you want to perform slightly more complex editing, you must cut and paste the original beforehand. There was a drawback.

Furthermore, the technique described in the above-mentioned publication requires a display device such as a CRT, which has the problem of increasing the price.

The present invention has been made to solve the above problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image editing device that allows easy designation of an editing range and allows easy understanding of editing operations such as movement.

[Means for Solving the Problem] In order to achieve the above object, the image editing device of the present invention has the following features:
A reading means that divides an input image into two parts and reads one part as a source part and the other part as a destination part, and recognition that recognizes an editing symbol that specifies the correspondence between a predetermined area of the source part and a predetermined area of the destination part. and an image editing means for developing an image in a predetermined area of the source part into a predetermined area of the destination part in accordance with the designated editing symbol.

Further, the editing symbol is made up of closed curves that designate predetermined areas of the source section and the destination section, respectively, and a line that connects the closed curves.

[Function] According to the above-described means, the editing symbol portion and the non-symbol portion are discriminated while reading the original line by line, and each of the discriminated areas is labeled. This labeling process is performed on all lines to create a labeling data table.

Then, from this table, a correspondence relationship between the coordinate value data of the closed area specified by the editing symbols of the source part and the destination part, and the source part and the destination part is created.

These two editing ranges usually do not have the same shape, so if they are different in size, either match the size of the source part to that of the destination part, or conversely change the size of the destination part to that of the source part. Modification operations such as scaling are performed accordingly.

In the second scan process, in the source part, the image editing part refers to the coordinate value data from the read image and stores only the image within the editing range, and then performs the scan process of the destination part, For areas outside the editing range, the read image is stored, and for areas within the editing range, image data within the editing range of the source section is taken in, expanded, and stored.

As a result, the specified area of the source part is moved to the specified area of the destination part, and the destination part is edited and output.

〔Example〕

Hereinafter, one embodiment of the present invention will be specifically described using the drawings.

FIG. 1 is a block diagram of an image editing apparatus according to an embodiment of the present invention. In the figure, ■ is an image input section consisting of an optical scanner, 2 is an image storage section that stores digitized binary images, and 3 is an image editing section 4 and an editing symbol recognition section 5 that recognizes editing symbols. The control section 10 is an image output section.

The editing symbol recognition unit 5 includes a determining unit 6 that determines whether or not it is an editing symbol, a labeling processing unit 7 that labels the determined symbol part and non-symbol part, and coordinate value data of the closed area. , a closed region data creation section 8 that creates a connection relationship between the source section and the destination section, and a closed region transformation operation section 9 that transforms the closed region of the source section or the destination section.

FIG. 2 is a diagram showing the configuration of the image input unit 1 of the present invention. The reading unit 22 reads the original 21 with a CCD sensor or the like while moving a light source and a reflecting mirror (not shown) from side to side. Since it is the same as that, detailed explanation will be omitted.

The reading section 22 of the present invention has a source section 23 and a destination section 2 separated by a dividing line 25 in the middle of the reading section.
After reading, the data is sent to the source section 23.
and a destination section 24.

Furthermore, in correspondence with the reading section 22 which is divided into a source section 23 and a destination section 24, the edited manuscript 31 is also divided into a source section 32 and a destination section 33 by a dividing line 34, as shown in FIG. . The editing symbol according to the present invention includes a closed curve 35 that specifies an editing range, and a line 36 that connects the closed curve 35 of the source section 32 and the destination section 33.

Editing symbols are written on the M draft using halftone markers or the like, but at this time, since the source part and destination part are determined in advance, there is no need to write arrows or the like to indicate the direction of the lines.

Recognition of the editing symbols configured in this way, editing range, and reading of the manuscript will be described in detail below.

FIG. 4 is a flowchart outlining the processing of the present invention, including the first scan (step 41) for recognizing editing symbols, and the second scan for reading the specified area of the source section and the destination section. The process consists of a second scan (step 42) and a process of outputting or storing the edited image (step 43).

FIG. 5 is a flowchart showing the detailed processing procedure of the first scanning process for recognizing editing symbols. In this first scanning process, the editing symbol portion and the non-symbol portion are determined while reading the original line by line (steps 50 and 51).

As mentioned above, the editing symbol is written with a halftone marker, etc., so the editing symbol recognition unit 5 determines the halftone part from the read density level and recognizes this as an editing symbol, which is what is called a digital copy. Editing symbols are identified using the same recognition method used in the machine.

Each region thus determined is labeled (step 52). Labeling is a process of assigning the same label number to all pixels belonging to the same connected component, and assigning different label numbers to different connected components.

FIG. 6 is a diagram for explaining labeling in reading lines n and n-1, 61 is a non-symbol part, 62
is the editing symbol part. Reading starts from the left of the reading line n-1, assigning the number "I++" to the non-symbol part 61, then assigning the number "2" to the symbol part 62, and assigning the number "3" to the non-symbol part 61, The number “4” is in the symbol part 62,
The number "5" is in the non-symbol part 61, the number "6" is in the symbol part 62,
The number “7” is assigned to the non-symbol portion 61. continue,
Numbers are similarly assigned to the symbol part and non-symbol part in reading line n, but they are of the same type (symbol part or non-symbol part) as the previous line (n - 1), and the previous line and current line (n ) are connected, the same number as the previous line is assigned. Therefore, each non-symbol part and symbol part of reading line n are numbered "'1" to ++ in order.
7 ++ is assigned, but the number of symbol part 62 is "4"
`` is connected to the symbol part 62 to which the number ``'6'' of the previous line (n-1) is assigned, so the number ``
At the same time as assigning the number ``4'', the number ``6''=``'4'' is stored in a table to be described later.

The above labeling process is performed for all lines to create a labeling data table as shown in FIG.
1), 72 is the number of elements in one line, that is, the total number of symbol parts and non-symbol parts, 73 is the number of the labeled non-symbol part (for example "1"), and 74 is the left and right coordinate values of that number (
(see FIG. 6), 75 is the number of the symbol part, and 76 is its coordinate value.

From this table, create the coordinate value data of the closed area specified by the editing symbols of the source part and the destination part, and calculate the correspondence between the source part and the destination part.
The label number in the closed area of the source part and the label number in the closed area of the destination part are stored and represented as a pair (step 53).

FIG. 7(b) is a diagram showing the result of labeling in this way, and shows the source part of label number Q and the label number Ω.
In this example, the destination part of , corresponds, and the source part of label number Q corresponds to the destination part of label number Q. Further, Ql and α are label numbers assigned to each editing symbol.

Since these two editing ranges usually do not have the same shape, the closed region transformation operation section 9 calculates the sizes of the closed regions of the source part and the destination part from the coordinate value data of the closed regions, and If the sizes are different, match the size of the source part to that of the destination part, or conversely, match the size of the destination part to that of the source part, perform deformation operations such as scaling, and use the deformation amount data. The image is passed to the image editing department IO (step 54).

FIG. 8 is a flowchart showing the detailed processing procedure of the second scan process. In this second scanning process, the image editing section 4 in the source section stores only images within the editing range from the read image by referring to the coordinate value data (step 80.81).

Next, the destination part is scanned,
For areas outside the editing range, the read images are stored (steps 82, 83, 84, 86). On the other hand, for the area within the editing range, the image data within the editing range of the source part corresponding to the destination part is imported and developed while performing a predetermined transformation operation based on the transformation amount data from the closed area transformation operation unit 9. and store or output (steps 83, 85, 86).

Through the above processing, the specified area of the source part is moved to the specified area of the destination part while being accompanied by a transformation operation, and finally only the destination part is output.

FIG. 9(a) shows an example of an input manuscript according to the present invention, and FIG. 9(b) shows an example of an output after editing processing according to the present invention.

In addition, as another embodiment of the present invention, by using a sheet of paper with nothing written in the destination area, it is possible to replace the area of the source area or to perform a selection operation from the area of the source area. By using an existing document as the destination section, it is also possible to insert a specified area of the source section into the document.

〔Effect of the invention〕

As explained above, according to the present invention, the editing range can be specified in the same way as using markers, so it is very simple, and the editing range of the source part and that of the destination part are connected by a line. Therefore, it is easy to understand in which area of the destination part the editing range of the source part is expanded, and editing work can be easily performed even on a device such as a CRT that does not have a display device.
