To the address (area). For example, in the control unit 6, from the image data shown in FIG.
When a command to read the image data of “i” and “u” is input, the control unit 6 accesses the memory area corresponding to “a”, “i”, and “u” of the first image storage unit 4. Then, the read image data is transferred to a predetermined area of the second image storage unit 8, for example, the area shown in FIG. 5 (b).

The image data transferred to the second image storage unit 8 and edited is then sent to the image output unit 10 and output in the form of visible information in the image output unit 10. in this case,
Since the storage content of the second image storage unit 8 is read by, for example, a horizontal line scan, the image data area in the second image storage unit 8 and the image data output by the image output unit 10 are stored. The display or print area is
It corresponds to each other.

Next, when outputting the image data shown in FIG. 5 (c) by the image output unit 10, in the same manner as above,
As shown in FIG. 5C, the image data “A” and “U” are accessed by the control unit 6 from the FIG. 5A stored in the first image storage unit 4. And is transferred to a memory area of the second image storage unit 8 designated in advance.
When this transfer is completed and the editing is completed, the image data in the second image storage unit 8 is read out to the image output unit 10. The display or print position of the image data output by the image output unit 10 corresponds to the position shown in FIG.

As described above, according to the conventional apparatus shown in FIG. 4, it is possible to arbitrarily edit the document information.

(Problems to be Solved by the Invention) The above-described conventional technique has the following problems.

That is, as described above, the conventional image output unit 10
When the information is output to, the image data is always transferred from the first image storage unit 4 to the second image storage unit 8 every time the information content changes, so that the image editing process is performed at high speed. There was a problem that I could not.

(Means and Actions for Solving Problems) In order to solve the above problems, the present invention relates to first storage means for storing digitally read image data, and the first storage means. In an image editing apparatus having a second storage unit for storing image data that has been image-edited and is extracted from the image data, the position information of the image data extracted from the first storage unit and the editing of the extracted image data. Position information of the second storage unit indicating the storage position of the subsequent data and at least transfer provided for each image data extracted for editing from the first storage unit, transfer is performed. A parameter storage unit that stores a flag indicating that the image data is not present, and transfer of image data from the first storage unit to the second storage unit based on the position information and the flag stored in the parameter storage unit. It is characterized in that the image editing process is performed at high speed by including the transfer control means for controlling.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. Also,
2 (a) is read by the image input unit,
The conceptual diagrams of the digital image data stored in the first image storage unit, and FIGS. 2 (b), (c), and (d) are the second diagram, respectively.
3 is a conceptual diagram of digital image data stored in the image memory of FIG. In this embodiment, it is assumed that the digital image data is output to the image output section in the order of (b), (c) and (d).

Assuming that the manuscript information read by the image input unit 2 is the same as the manuscript information described in the conventional example, the first image storage unit 20 stores the fifth manuscript information as shown in FIG. One page of digital image data exactly the same as that shown in FIG. The digital image data for one page stored in the first image storage unit 20 is the data of the area designated by the parameter stored in the parameter storage unit 22, and the line 20a, the control unit 24, and the line It is transferred to a designated area of the second image storage unit 26 via 24a.

Here, an example of the parameters and flags stored in the parameter storage unit 22 will be described with reference to FIG.

The parameters 10, 20, 30 in FIG. 3 are parameters that define the memory area on the first image storage unit 20, and in the present example, the parameters 10, 20, 30 are respectively shown in FIG. 2 (a). PARA-10, PARA-20, PARA-
It refers to 30 areas. This parameter 10, 20, 3
0 is specifically the coordinates (x,
y) and parameters of length in the horizontal direction (x direction) and the vertical direction (y direction) starting from the coordinates (x, y). This parameter 10, 2
0 and 30 are sequentially sent from the parameter storage unit 22 to the address conversion unit 28 through the line a in FIG.

On the other hand, the parameters 11, 21, and 31 in FIG. 3 are parameters that define the memory area on the second image storage unit 26, respectively, and in this example, PARA- shown in FIG. It refers to the area of 11, PARA-21 and PARA-31. Specifically, the parameters 11, 21 and 31 are composed of the parameters of the coordinates of the upper left corner of each area and the parameters of the lengths in the horizontal and vertical directions starting from the coordinates, as in the previous case. There is. These parameters 11 and 2
1, 31 are sequentially sent to the address conversion unit 30 through the line b of FIG.

Also, output (1), output (2) and output (3) in FIG.
The flags "1", "0", and "-1" in are signals for instructing transfer, non-transfer, and clear, respectively. The transfer flag "1" is transmitted to the transfer flag transmission line c, and the clear flag "-1" is transmitted to the clear flag transmission line d.

Returning to FIG. 1 again, description will be made. The image data transferred to the designated area of the second image storage unit 26 is output to the image output unit 10 when the editing process is completed.

Next, the operation of this embodiment will be described with reference to FIGS.

One page of document information is read by the image input unit 2, and the above-described digitized image data is stored in the first image storage unit 20. When one page of image data is stored in the first image storage unit 20, the control unit 24 sequentially reads the parameters and flags stored in advance in the parameter storage unit 22 and sets the parameters to the line a, b, and the transfer flag "1" and the clear flag "-1" are sent to the transfer flag transmission line c and the clear flag transmission line d, respectively.

First, from the parameter storage unit 22, the parameters 10, 2
0 and 30 are sequentially sent to the first address conversion unit 28 through the line a. The first address conversion unit 28 converts the parameters 10, 20, 30 into addresses of the first image storage unit 20, and
The addresses of the areas of PARA-10, PARA-20, and PARA-30 shown in FIG. 2 (a) are sequentially accessed.

Further, the transfer flag “1” is sent from the parameter storage unit 22 to the transfer flag transmission line c, and then the parameters 11, 21, 31 are sequentially transferred from the parameter storage unit 22 through the line b to the second address conversion unit 30. Sent to. The second address conversion unit 30 uses the parameters 11, 21, 3
1 is converted into an access of the second image storage unit 26, and the area of PARA-11, PARA-21, PARA-31 shown in FIG. 2 (b) is converted to the second image storage unit 26. The addresses of are sequentially accessed.

As a result, the image data “A” in the area of PARA-10 of the first image storage unit 20 is stored in the second image storage unit 26.
1st image storage unit 2 transferred to the area of PARA-11
The image data “i” in the area 0 of PARA-20 is transferred to the area PARA-21 of the second image storage unit 26, and the image data “i” in the area PARA-30 of the first image storage unit 20 is displayed. U ”is transferred to the area of PARA-31 of the second image storage unit 26.

When the transfer of the image data to the second image storage unit 26 is completed and the image data as shown in FIG. 2B is stored in the second image storage unit 26, these The image data of 1 is sequentially read to the image output unit 10. The image output from the image output unit 10 is obtained by extracting necessary information from the original document information and laying out this information in a predetermined area.

Next, when the output image in the format as shown in FIG. 2 (c) is obtained subsequently to the output image in the format as shown in FIG. Since the flag shown in the output (2) of the figure is stored, this flag is read by a command from the control unit 24.

That is, the flag “0” that is not transferred is stored in the parameter storage unit 22 between the parameter 10 and the parameter 11 and between the parameter 20 and the parameter 21, and the clear flag “−1” is stored between the parameter 30 and the parameter 31. Is remembered. Therefore, in the storage contents of the second image storage unit 26 shown in FIG.
-11 and PARA-21 areas retain the image data as they are. Also, the contents of the area of PARA-31 are cleared. Specifically, the image data “0” from the control unit 24 passes through the line 24b and the PARA- of the second image storage unit 26 is transmitted.
Written in 31 areas.

Therefore, the content stored in the second image storage unit 26 is
The result is as shown in FIG. 2 (c). At this time, as described above, the image data “A” and “I” of PARA-11 and PARA-21 are not transferred from the first image storage unit 20 to the second image storage unit 26, but transferred before. Since the image data that has been used is used as it is, the transfer is not necessary and the transfer time is increased.

Next, when the output of the format shown in FIG. 2D is performed subsequently to the output of the format shown in FIG. 2C, the output (3 ) Flag is read from the parameter storage unit 22.

That is, the flag “0” without transfer is stored in the parameter storage unit 22 between the parameters 10 and 11, and the clear flag “−1” is stored between the parameters 20 and 21. Therefore, a transfer flag “1” is stored between the parameter 30 and the parameter 31. Therefore, in the storage content of the second image storage unit 26, the content of the area of PARA-11 holds the image data as it is. In addition, for the area of PARA-21,
Image data "0" is sent from the control unit 24 through the line 24b, and the area of PARA-21 is cleared. For the area of PARA-31, the image data “U” stored in the area of PARA-30 of the first image storage unit 20 is transferred to the area of PARA-31 of the second image storage unit 26. It

In this way, the second image storage unit 26 stores the second
The image data shown in FIG. 3D is stored. The image data stored in the second image storage unit 26 is output to the image output unit 10 in the same layout.
In this example, the image data “A” in the area of PARA-11 is stored in the first image storage unit 20 to the second image storage unit 2
Since the image data that has been transferred before is not transferred to No. 6 and is used as it is, the transfer time is not required and the speed is increased.

As described above, according to the present embodiment, when the same image data as the image data transferred to the second image storage unit 26 is used as the image data for the next output, the image data need not be transferred. Since it is used as it is, the transfer time can be reduced and high-speed processing can be performed.

Although "1", "0" and "-1" are used as the transfer, non-transfer and clear flags in the above embodiment, the present invention is not limited to this, and other numerical values may be used. Of course good things.

(Effect of the Invention) As is apparent from the above description, according to the present invention, the first
Since the amount of image data transferred from the image storage unit to the second image storage unit is less than that of the conventional device,
The time required for editing processing can be shortened.
