Abstract

PURPOSE:To efficiently register only desired image data to a memory means by instructing a cut-out area with a pointing device and storing unerased image data at a minimum area including the image data. CONSTITUTION:A pointing device 8 instructs a menu displayed at a window 2a and instructs the cut-out area in image data displayed at the window 2a with diagonal coordinates P1 and P2, etc. Namely, in the image processing, when a cut-out area 22 is instructed by the device 8, a CPU 1 rewrites all bit data corresponding to the bit at the outside of the area 22 instructed by the device 8 out of the image data constructed at a RAM 4 to zero. As the result, the outside of the area 22 out of document image data 21 displayed at the window 2a is erased, and by a writing command, the image data of the inside of the area 22 are written into an optical disk device 7 at the cut-out area size. Thus, only the desired image data can be efficiently registered to a device 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for electronically processing a document as image data.

[Conventional technology]

Conventionally, in electronic file devices that register document image data read from an input unit in a storage medium such as an optical disk, the image data read for each size of the input document is temporarily stored in a random access memory such as a RAM, and then the contents of that memory are stored. The image data in the RAM is usually registered on the optical disc after editing such as deletion.

In particular, regarding deletion editing, the image data read from the input section is displayed once on a display section, and for example, if the input image is a newspaper article and you want to create a clipping of the newspaper article, you can leave it as is. Usually, a method is adopted in which the desired area is surrounded by a pointing device or the like and the area outside the area is erased.

[Problem that the invention seeks to solve]

However, when registering image data to an optical disc,
Since the size read from the input section is registered as is,
There is a problem in that part of the stored data that is no longer meaningful is also registered on the optical disc, which significantly reduces the storage efficiency on the optical disc.

This invention was made to solve the above problems, and by storing the image data that remains without being erased from the display means in the smallest area containing this image data,
It is an object of the present invention to provide a document image processing device that can efficiently register only desired image data in a storage means.

[Means for solving problems]

A document image processing apparatus according to the present invention includes: a first image storage means for storing image data; a display means for displaying the image data stored in the first image storage means in a window of a predetermined size; an instruction means for instructing a predetermined area in the image data to be displayed; an erasing means for erasing image data displayed outside the area specified by the instruction means from the window and the first image storage means; A second image storage means is provided for storing image data displayed inside the area designated by the means in area size.

[Effect]

In this invention, the image data stored in the first image storage means is displayed in the window of the display means, and when a desired area is designated by the indicating means, the erasing means is directed to the area indicated by the indicating means. The image data displayed outside the display device and the first image storage device are erased from the display device and the first image storage device. Due to this erasure, only the image data existing inside the area designated by the designation device is displayed within the window of the display device. The image data existing inside this area is stored in the second storage means in a desired area size specified by the instruction means.

I remember that. Therefore, by changing the contents of the VRAM 5, an image can be displayed or deleted within the window 2a. Reference numeral 6 denotes a disk device (DISK) that stores management information and the like for image data stored in an optical disk device (OD) 7 serving as a second image storage means. The optical disk device 7 stores image data in a non-rewritable manner. Reference numeral 8 denotes a pointing device (FD) serving as an instruction means of the present invention, which indicates the menu displayed on the window 2a or indicates the cutout area in the image data displayed on the window 2a, for example, using diagonal coordinates. . When the cutting area is designated by the pointing device 8, the CPU 1 rewrites all bit data corresponding to bits outside the area designated by the pointing device 8 to "0" among the image data constructed in the RAM 4, Of the image data displayed on the window 2a, the area outside the clipping area is erased, and the image data inside the clipping area displayed on the window 2a is erased with the clipping area size based on a write command issued from the keyboard 3, for example. When writing to the optical disk device 7, necessary management information is written to the disk device 6. An image league (IR) 9 converts the original image into an electrical signal and writes it into the RAM 4.

1o is a bus that connects the above-mentioned 2 to 9 to the CPU 1.

Figure 2 shows the bitmap display 2 shown in Figure 1.

When the document image data 21 stored in the disk device 6 or the document image data 21 read from the image reader 9 is developed in the RAM 4, the document image data 21 is displayed in the window of the bitmap display 2 as shown in FIG. 2a is displayed on the entire screen. Here, the pointing device 8 is moved on a plane (not shown) to point the arrow cursor 11 to the diagonal coordinate point P1 (xa, ya), and while the big button 12 is pressed down, the pointing device 8 Move to point P2
When you specify (xb, yb), big button 12
When you stop pressing , the diagonal coordinate point PH(xa,
ya) and the position coordinates of point P2 (xb, yb) are sent to the CPUI, and the cutout area 22 is displayed as a frame. For this reason, the configuration is such that the cutting frame continues to be generated in accordance with the movement of the pointing device 8 until the big button 12 is not stopped being pressed after the point P1 is specified.

FIG. 4 is a schematic diagram illustrating a document management file constructed in the disk device 6 shown in FIG. . The keyword 31a includes a keyword added to each document, such as rKEY-
The address 31b stores a record address such as "al" of a page management file 41 in which management information for one page of the corresponding document is stored. Note that a record including the keyword 31a and address 31b is called a document management record 32.

FIG. 5 is a schematic diagram illustrating the structure of the page management file 41 shown in FIG. 4, and the same parts as in FIG. 4 are given the same reference numerals.

As shown in this figure, the page management file 41 corresponds to the address 31b of each first page of the document management file 31.Document size 4]a 9Image size 41b9Image coordinates 41C2Document storage position 41dThird page chain address 41e etc. are stored, and the above 41a to 4
One page management record 42 is composed of 1e and the like.

Therefore, one page management record 42 manages image information for one page of a document.

The document size 41a stores the document size that the operator originally intended to register in the optical disk device 7, such as "A4". That is, regardless of the size of the image data registered in the optical disk device 7, the size (A4) of the document to be handled (placed) by the operator in this device is stored. In the image size 41b, the vertical and horizontal sizes of the image data stored in the disk device 6 are written in dot numbers (SXl, 5yl) tα. In the image coordinates 41c, relative coordinates (xi , yl). The document storage column 41d stores the storage address of the image data of the page to be stored in the optical disk device 7 as the addresses of the first sector (si) and the last sector (El). The next page chain address 41e stores the address (a2, etc.) of a record in which information about the next page is stored when a subsequent page exists. In addition,
If rFFJ+6 is written in the chain address 41e of the next page, this indicates that there is no subsequent page and that the page is the final page.

FIG. 6 is a schematic diagram illustrating a document size table formed in the RAM 4 shown in FIG. 1.

Components that are the same as those in FIG. 1 are given the same reference numerals.

In this figure, reference numeral 51 denotes a document size table, which includes the number of dots in the X direction 51b, the number of dots in the Y direction 51c, etc. for each document size 51a.

When reading image data from the optical disk device 7 and displaying it on the bitmap display 2, the original size 51a
In the figure, if the document size 51a is A4, the number of dots in the X direction is 51b, and the number of dots in the X direction is 51c.
56J.

This shows the state in which r4677J is stored.

Next, referring to FIG. 7, the operation of registering a cutout of document image data according to the present invention will be described.

FIG. 7 is a flowchart illustrating the procedure for registering a cutout of document image data according to the present invention. Furthermore, (1)
~(9) shows each step. Furthermore, for the sake of explanation, it is assumed that an image including image data to be registered in the optical disk device 7 is read from the image reader 9 at a resolution of 8 dots per mm, and is already stored in a predetermined area in the RAM 4. .

First, using the pointing device 8, instruct which part of the image displayed on the bitmap display 2 is to be registered in the optical disk device 7 as image data in accordance with the procedure described in the explanation of FIG. The cutout area 22 is specified (1). Next, the CPU 1 erases the document image data 21 outside the cutout area 22 specified in step (1) (2). This erasure is performed by R.A.
This is performed for document image data stored in M4 and VRAM4. In this embodiment, the resolution of the bitmap display 2 and the resolution of the image data loaded into the RAM 4 are both the same as 8 trees per yJ11, so the VR
The difference between erasing AM5 and RAM4 is that the processing is the same except for the erase start position. Next, the upper left corner coordinates of the cutout area 22 in the RAM 4 are stored in the work area in the RAM 4 as data to be written in the image coordinates 41c of the page management record 42 (3
).

Next, the number of vertical and horizontal dots corresponding to the cutout area 22 in the RAM 4 is determined by the image size 4 of the page management record 42.
It is stored in the work area in the RAM 4 as data to be written to 1b (4). Next, the image data within the cutout area 22 specified in step (1) is written to the optical disk device 7 (5). Then, in steps (3) to (5), R
Image coordinates 41c 9 Image size 41b 9 Document storage position 41d and document size 41 stored in the work area in AM4
rFFJ to chain address 41e of a and next page
is written to the page management file 41 as a series of page management records 42 with (6). Next, it is determined which page of the document the page management record 42 written in step (6) belongs to (7). With this judgment,
If it is the last page, the control is terminated, and if it is the first page, the address 31b of the first page of the record in the document management file 31 is changed (8), and the control is terminated. If there is, the chain address 41e of the next page of the record corresponding to the previous page of the page management file 41 is updated (9), and the control is ended.

In the above embodiment, a case has been described in which the part to be left as image data in the image erasing operation is set as a rectangle (cutting area) and the image data inside this rectangle is stored in the optical disk device 7. Instead of specifying an area, only a polygonal area in which each vertex of the part to be registered is specified by the pointing device 8 may be registered in the optical disk device 7.

Furthermore, in the above embodiment, the case where image data is registered in the RAM 4 at a resolution of 8 lines per mm has been explained, but the resolution may be 16 lines per mm. Since twice the image data is stored, the vertical and horizontal sizes from the upper left corner point of the cutout area 22 specified in the erase operation should be twice the values in the case of 8 lines per mm. Not even.

Furthermore, the device (system) shown in the above embodiment is not limited to this as long as the present invention is applicable.
The connected device may be changed. Further, it may be configured to function by being connected to another device (system) via a local area network (LAN) or the like, or it may be a single device.

〔Effect of the invention〕

As explained above, the present invention includes a first image storage means for storing image data, a display means for displaying the image data stored in the first image storage means in a window of a predetermined size, and a display means for displaying the image data in the window. an instructing means for instructing a predetermined area in the image data to be displayed; and an erasing means for erasing image data displayed outside the area indicated by the instructing means from the window and the first image storage means;
and second image storage means for storing image data displayed inside the area specified by the instruction means in an area size, so that only the desired image data is stored in the area size specified by the instruction means. Image data can be stored efficiently in the second storage means, and when the second storage means is configured with a storage medium that stores data in a non-rewritable manner, the image data storage efficiency can be greatly improved. Furthermore, compared to a document image processing device that has a compression means that stores image data that has been erased from the image data displayed on a display means at the screen size and compresses it to a certain ratio and stores it, Since only the necessary minimum amount of image data can be stored in the second image storage means at high speed, the writing process can be completed in an extremely short time.
