Abstract

PURPOSE:To permit an operator to easily judge the contents of an index picture and to efficiently retrieve an objective document by enlarging and displaying the index picture whose registered document consists of the same format. CONSTITUTION:A pointing device DP8 designates an optional segment area in document picture data. Thus, a CPU1 permits a CRT display device 2 to enlarge document data in the area designated to be split into prescribed numbers, and permits a RAM4 to write it as the index picture of the document data. Thus, even if document picture data has the same document format, it can be registered with setting a part to be especially emphasized as the index picture. Consequently, document picture data having the same document format can be identified and the retrieval efficiency of the index picture can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document image processing device that electronically processes document data and image data in parallel.

, a window is displayed, and an image is displayed in the window, for example, at a high resolution of 8 lines per mm. 3 is a keyboard (KB) for inputting character data and functions.

4 is a RAM, which is used as a work area for storing image data being displayed and editing image index data. A video RAM (VRAM) 5 stores data displayed by the bitmap display 2 in bit units. A disk device (DISK) 6 stores files and management information of image data stored in the optical disk (00) 7. Reference numeral 8 denotes a pointing device (FD) which also serves as a specifying means of the present invention, and is used to specify a position on the display screen displayed on the bitmap display 2. Reference numeral 9 denotes a bus (BUS), which transfers data handled by 2 to 8 above to the CPUI, and transfers data processed by the CPUI to 2 to 8 above. The CPUI also serves as index image writing means of this invention.

Figure 2 shows the bitmap display 2 shown in Figure 1.
1 is a schematic diagram illustrating the appearance of the pointing device 8, in which 11 is a window and an arrow cursor 12 is displayed at the lower right of the window 11. The arrow cursor 12 is displayed while moving on the bitmap display 2 as a pole (not shown) placed at the bottom of the pointing device 8 rotates, and the rotation amount is converted into a movement amount by the CPU. . 13 is a big button, and when this big button 13 is pressed, the position coordinates of the bitmap display 2 indicated by the arrow cursor 12 are notified to the CPUI. Note that when the big button 13 is pressed, the CPU recognizes the position coordinates indicated by the arrow cursor 12 and the pressed state of the big button 13 at the same time.

FIG. 3 is a schematic diagram illustrating the index image registration work according to the present invention, and the same parts as in FIG. 1 are given the same reference numerals.

In this figure, 21 is a document, and the index image 22 for this document 21 is set at diagonal coordinates P1 (Xa ty
a), P2 (xb, yb) is indicated by operating the pointing device 8 with the arrow cursor 12, and the area is displayed as a rectangle 23.

Next, the operation for specifying the index image 22 will be explained.

Rectangle 23 is big button 1 of pointing device 8
3 is pressed, and while the big button 13 is being pressed, a rectangle 23 whose diagonal lines are the first pressed point, diagonal coordinate P1, and diagonal coordinate P2, which is indicated by the current arrow cursor 12. is retained. Therefore, the diagonal coordinate P2
When , the rectangle 23 is also regenerated. When the big button 13 is stopped being pressed, the diagonal coordinate P2 indicated by the arrow cursor 12 is fixed, and the area that will become the index image 22 is determined.

FIG. 4 is a schematic diagram illustrating index image search according to the present invention, and the same parts as in FIG. 1 are given the same reference numerals.

In this figure, 31a to 31h are index image areas (areas divided into eight by dotted lines), and each index image area 31a to 31d has index images 32a to 31h.
2d is displayed.

FIG. 5 is a conceptual diagram illustrating the correspondence between image data and index images stored on the optical disc 7 shown in FIG. 1.

In this figure, 41a and 41b are image data, and index images 42a and 42b corresponding to the image data 4ia and 41kl are written in independent storage areas of the optical disc 7, respectively.

Note that if there is a document consisting of multiple pages, the index image is generated from the image data of the first page.

FIG. 6 is a schematic diagram illustrating the file structure of the disk device 6 shown in FIG.
b, index image size 51C, and pointer 51d to the page information record are stored. Keyword 5
1a stores keyword information attached to each document, such as "rKEY-A1". The index image storage position 51b is a leading sector indicating in which area of the optical disc 7 the index image data is stored;
It stores the last sector, such as rsl, EIJ, etc.

The index image size 51C stores the vertical and horizontal sizes of the index image in number of dots. The page information record register 51d stores information about each page of a document managed in the document management record 52, which is composed of a series of information such as a keyword 51a, an index image storage location 51b, and an index image size 51c. A pointer to the record that is being stored.

As can be seen from this figure, when the CPU 1 searches the document management file 51 for a keyword 51a that matches the conditions specified by the operator, the location and size of the index image related to the keyword 51a are determined by the index image storage location 51b and the index image storage location 51b. The configuration is such that the image size 51c can be accessed to determine the information, and if one wishes to obtain information on pages 1 to n, the information on each page can also be determined by using the pointer 51d to the page information record.

Next, the index image creation operation according to the present invention will be explained with reference to the flowchart shown in FIG.

FIG. 7 is a flowchart illustrating the procedure for creating an index image according to the present invention. In addition, (1) to (
10) shows each step. Further, in this embodiment, the image data to be registered on the optical disc 7 is already stored in the RAM.
It is stored in J at a resolution of 8 dots per am. Furthermore, the index image displayed on the bitmap display 2 at the time of index image search is limited to the fourth index image at most.
The size of the rectangle 23 is automatically limited when specifying an index image so that it does not become larger than the window 11 shown in the figure divided into eight parts.

First, the pointing device 8 is operated to input the upper left corner point of a rectangular area that will become an index image (1).

That is, after pointing the diagonal coordinate P1 to the arrow cursor 12, the pick button 13 is pressed.Next, the CPU determines whether the pick button 13 continues to be pressed (2). In this judgment, if No, proceed to step (8) onwards, and if YES, input the position coordinates currently indicated by the arrow cursor 12 on the bitmap display 2 (3) 0. Then, the coordinates input in step (1) are input. Whether or not the rectangle whose diagonal is the line connecting the left point and the lower right point input in step (3) exceeds the 8-divided area of the window 11 that displays the index image when doubled vertically and horizontally, that is, the rectangle The CPU 1 determines whether or not it is within the divided area (4). If this judgment is No, step (2
), if YES, the CPU 1 determines whether the coordinate position of the arrow cursor 12 input in step (3) has changed compared to before (5), and if this determination is YES, the process proceeds to step (2). Go back and, if No, erase the rectangle that was previously displayed on the bitmap display 2 (6), and draw a new rectangle whose diagonal is the line connecting the input point of step (1) and the input point of step (3). (7) Return to step (2) and repeat steps (2) to (7) while the pick button 13 of the pointing device 8 is pressed.

On the other hand, if the answer is No in step (2), that is, if the CPU determines that the pick button 13 has stopped being pressed, then the part of the image data in the RAM 4 that corresponds to the rectangular area currently displayed on the bitmap display 2 The index image, which is enlarged twice vertically and horizontally, is stored in RAM4.
(8) 0 Next, the created index image is written to the optical disc 7 (8), and the index image storage position 51b in the optical disc 7 of the index image written to the optical disc 7, and the index image size 5
Each data (document management record) is written in the document management file 51 (provided in the disk device 6) shown in FIG. 6 (10).

In the above embodiment, an enlarged index image is written on the optical disk 7, but an index image that is not enlarged may be written on the optical disk 7 and enlarged when the index image is displayed.

Further, in the above embodiment, for convenience, the explanation was given on the assumption that the registered image data of 8 dots per mm is stored in the RAM 4, but the image data is m! It goes without saying that if the registered image data of 16 dots per image is stored in the RAM 4, the enlargement process in step (8) shown in FIG. 7 may be omitted.

〔Effect of the invention〕

As explained above, the present invention includes a designating means for designating a cutting area of document image data displayed on a display, and a designating means for designating a cutting area of document image data displayed on a display, and a designating means for designating a display area of a display for document image data within the cutting area designated by the designating means. An index image writing means is provided for enlarging the area size into a number of areas and writing it into the storage means as an index image of this document image data, so even if the document image data has the same document format, particularly emphasized parts can be indexed. Since it can be registered as an image, document image data having the same document format can be identified, and index image search efficiency can be greatly improved.

Furthermore, since it is only necessary to register document image data within a designated area, the index image registration area can be set to a minimum, and memory efficiency can be greatly improved.
