Abstract

PURPOSE:To simplify a filing job by extracting a character string of an optional retrieving title out of a text image data and registering the title in character codes. CONSTITUTION:The image data on a text read into a data buffer 53 is displayed on the screen of a bit map type display device 3 and at the same time a character string area is designated to the text via a pointing device 4 serving as a position pointing means. That is, the characters are recognized through an optical character reader OCR function processing part 52. Then the character string is converted into the character codes and registered as a document title after a text area is read. Thus it is possible to simplify a series of filing jobs including the registration of titles, etc., into an index, etc.

Description

[Detailed Description of the Invention] This invention relates to the improvement of electronic filing systems, workstations, and other electronic filing devices having various image data processing functions, and particularly relates to the improvement of electronic filing systems, workstations, and other electronic filing devices having various image data processing functions, and in particular, regardless of the text format. , a character code that simplifies filing work by configuring the text image data to extract the character string of an arbitrary search title and allowing quick and easy registration of titles using character codes. The present invention relates to an electronic filing device having a title processing function.

In general, information processing devices such as electronic filing systems are equipped with a function to process image data.

The image data imported into the system is stored page by page, and each page is registered and registered as a single document.
Saved.

In conventional filing systems having such an image data processing function, when filing image data, the title of each document, that is, the search title for indexing, is generally registered using a keyboard or the like to enter the character code. The information is entered.

In this way, in conventional filing systems, it is necessary to enter the index search title separately from the image data using a keyboard or other operation.
Registration operation is troublesome.

One of the conventional methods to solve this inconvenience is to
In order to extract a character string as a title from a text image, set an area such as a character string on the text data in advance, and use the OCR (Optical Character Reader) function, that is, the character recognition function, to extract the character string from the image input section. A filing method is also used in which a text image data is read from a text image, and at the same time, a prespecified character string, etc. of the read text image is read by the 001 function, converted to a character code, and a text title is registered.

However, in the conventional filing method using this 001 function, the area where character recognition is possible is set in advance, so there is a disadvantage that it cannot be applied to filing work of text data other than the same format.

Furthermore, if there is a positional shift in the text data due to the performance of the image input unit, there is also the problem that the read character string may deviate from the designated area, resulting in failure to read the 001 function.

Furthermore, since the area where one character can be recognized is set in advance, if the title is registered after reading the text, which is the so-called retrofit method, the area where characters can be recognized by the 001 function is already set for the data to be filed. There have been many inconveniences, such as the inability to register a title if it does not match the area of the character string of the image data input as the image data.

The present invention aims to solve these inconveniences in conventional electronic filing devices equipped with an image data processing function and a text image document title registration function.
Since the possible area for character recognition by the 01 function is set in advance, it cannot be applied to text data other than the same format, and the text data is read first and the title is registered later. In the so-called retrofit method, if the area where characters can be recognized by the 001 function and the character string area of the data that has already been input as filing data do not match, the title cannot be registered as a retrofit and the filing process By solving the inconvenience of poor operation efficiency and configuring the text image reading area using the 001 function to be freely set, it is possible to register text images in all formats using character codes, and to In order to avoid being affected by the positional shift of text data due to the performance of the input section, and as a filing operation procedure, it is necessary to register the title after reading only the text data. An object of the present invention is to provide an electronic filing device that allows easy registration and improves the operability of filing processing.

In order to solve this problem, the present invention includes a bitmap type display device capable of displaying an image, an image input means capable of inputting an image, a code input means such as a keyboard capable of key input, and a data buffer storing image data. It is equipped with a memory and a central processing unit such as a CPU that controls each of these parts, and has an image data processing function.

and an electronic filing system having a document registration function including a function of inputting and storing a document name in character code when registering one document, and reproducing and displaying the character code when searching for a document, image data stored in the data buffer memory. a text area specifying means for specifying an area within the above text; and an OCR function means for converting image data in the area specified by the text area specifying means into code data.

title registration means for registering a character code converted by the OCR function as a title in an index of data text, and on a document registration display screen, the text area designation means selects a text area on the data buffer memory by the text area designation means. is specified, the text area is read by the OCR function means, and the character string in the area is converted into a character code and registered as a document title.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of an electronic filing device having a character code title processing function according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the configuration of essential parts of an electronic filing device having a character code title processing function according to the present invention. In the drawing,
1 is an image input device such as a scanner, 2 is an optical disk device (ODD), 3 is a bitmap display device, 4 is a pointing device, 5 is a system main unit, 51 is its file management processing unit, and 52 is an OCR function processing unit. 53 is a data buffer, 54 is a coordinate/bitmap width conversion map, 55 is a coordinate/bitmap width conversion processing section, 56 is a program memory, and 57 is a video memory.

In the electronic filing device of the present invention shown in FIG. , the character string area on the text can be specified, that is, the area where characters are recognized by the OCR function processing section 52 can be specified.

In addition, in order to convert the coordinates of the specified area to the bitmap width, a coordinate/bitmap width conversion map 54 is used.
and a coordinate/bitmap width conversion processing section 55.

Other configurations are basically the same as conventional electronic filing devices.

The operation of registering a document title by the electronic filing device of the present invention is as follows.

Text image data read by an image input device 1 such as a scanner, or an optical disk device (O
For text image data already written on a storage medium such as DD) 2.

When registering a search title as an index, text data to be registered is first written into the data buffer 53 in the system main unit 5.

At the same time, the text data is displayed on the screen of a bitmap display device 3, which is a display means such as a CRT or LCD.

FIG. 2 shows the electronic filing device of the present invention.
In Figure 6, which is a diagram showing an example of the storage state of data on the data buffer when text data is read, MA indicates a designated area.

The data of the text image to be registered written in the data buffer 53 is stored in a state as shown in FIG.

On the data buffer 53 of FIG. 2, a desired area MA is specified in order to extract a character string of text image data as a title.

As shown in FIG. 2, when the image data of the text to be registered is written into the data buffer 53, the next third
A title setting screen as shown in the figure is displayed.

FIG. 3 is a diagram showing an example of a title setting screen when registering a text image in the electronic filing device of the present invention.

When the area in which one character recognition is to be performed is specified using the pointing device 4 in the displayed state of the title setting screen shown in FIG. 3, the area MA on the data buffer 53 is set as shown in FIG. 2 above.

Then, on one display screen, as shown in FIG. 3, the character string in the designated area MA is displayed in a character pattern in the lower display area rTITLEJ.

In addition, in the area on the far right, you are asked whether or not you want to register with this title [○K? Questions like J will be displayed.

For example, by entering rYesJ,
The title is registered using those characters.

The following Figure 4 is a diagram illustrating bitmap conversion processing of a designated area of a text image using the OCR function in the electronic filing device of the present invention. , 0) is its coordinates, A is the start point of the designated area MA, and (X
^tyA) is its coordinate, B is the end point, (Xs
t Ys ) indicates its coordinates.

Regarding the text display area on the display screen in Figure 3 above, as shown in Figure 4, the upper left corner is the origin 0.
Take the coordinate axis Xv'j, and input the conversion map (coordinate/bitmap width conversion map 54 in Figure 1) that corresponds to this coordinate and the bitmap width of the text area on the display screen into a magnetic disk, etc. .

O by a pointing device (4 in Figure 1) etc.
Specify area MA where character recognition is to be performed using the CR function.

For example, two points, a start point A and an end point B, of area MA are specified diagonally.

Then, based on the coordinate information of the start point A and the end point B, the position of the area MA on the bitmap is calculated as follows.

The position on the bitmap of the start point A of the specified area MA (2,400XYA +XA) and the area MA
The horizontal width ΔX (XB-X^) and the vertical width ΔY (YB-Y^) are determined.

From the information on these bitmaps, position information of the data area of the text image to be subjected to character recognition can be obtained on the data buffer 53 of FIG.

Next, the operation at the time of title registration will be explained with reference to a flowchart regarding the electronic filing device having a character code title processing function according to the present invention.

FIG. 5 shows the electronic filing device of the present invention.
In one drawing, which is a flowchart showing the flow of main processing at the time of title registration, #1 to #7 indicate steps.

In the image document registration process, first step #
1, from the image input device 1 such as a scanner or the optical disk device 2 shown in FIG. The data is read into the data buffer 53 in the camera and displayed on the screen of the bitmap display device 3 via the video memory 57.

In step #2, an area for character recognition by the OCR function processing unit 52 is specified on the title setting screen using a position indicating means such as the pointing device 4 (
(See Figures 2 and 3).

In step #3, data in the designated area is read by the OCR function (see FIGS. 3 and 4).

In step #4, the user determines whether the content of the character string data displayed in the rTITLEJ display area on the screen is suitable for use as a title (
(See Figure 3).

The judgment in step #4 is made when the content of the character string data displayed in the display area of rTITLEJ is not suitable as a title. Depending on the situation, this is a step for manually inputting text using the keyboard when an appropriate character string cannot be found to indicate the text content.

And when respecifying the area for single character recognition.

Returning again to step #2, the same process is repeated.

Also, when you do not use the character string data displayed in the rTITLEJ display area as a title, or
When you cannot find the appropriate character string data for the title and want to input it manually using the keyboard,
This is indicated by key input or item selection (response to the question "OK?" in FIG. 3).

Then, when performing manual input, the process advances to step #5.

On the other hand, as a result of the judgment in step #4, rT
If the content of the character string data displayed in the display area of ITLEJ is suitable for use as a title, the process advances to the next step #6.

In step #6, the text data displayed in the rTITLEJ display area on one screen is registered as a search title, and at the same time, the image data is filed.

In step #7, it is determined whether or not to register another text, and if the registration work is to be continued.

Return to step #1 again and repeat the same process.

If no other text data is to be registered, the flow shown in FIG. 5 is ended.

Through the processing in steps #1 to #7 above, a character string to be used as a title is extracted from the text image data by the OCR function, converted into a character code, and registered as the title of the document.

As described above, in the electronic filing device of this invention,
It is now possible to freely set the reading area for character strings in text images using the OCR function, and it is possible to register text images in all formats using character codes, eliminating the effects of positional shifts due to the performance of the image input section. I don't accept it.

Furthermore, since it is possible to freely set the area for single-character recognition, the filing procedure involves reading only the text data first and then registering the title. can be freely registered.

In the above embodiment, a case has been described in which a character recognition area is specified in order to convert the image data selected on the title setting screen of FIG. 3 into a one-character code title.

However, depending on the software for executing the OCR function, the recognized character size may be set in advance.

When performing character recognition in a text image using such software processing, it is only necessary to specify 5 character sizes,
There is no need to specify an area for character recognition.

That is, in this case, instead of specifying the area for single character recognition, the configuration is such that the character size can be specified.

For example, when filing newspaper clippings, etc.
By focusing on the font size of the heading and specifying the font size, it is possible to automatically recognize the font.

Therefore, in a system that employs such software processing, the electronic filing device equipped with the character code title processing function of the present invention can be configured so that the character size can be specified when extracting a search title. It is possible to register in , and this case is also included.

According to the electronic filing device equipped with a character code title processing function of the present invention, text image filing work is not limited to data in a fixed format as in the past, but can be performed using arbitrary data. It becomes possible to extract the character string of the search title from the text image data of the format and register it as a character code.

In addition, even for text image data that has already been written to image memory or optical discs, the character string used as the title can be extracted from any area and registered and recognized using the character code. is also easy to process.

Therefore, compared to traditional electronic filing devices,
A series of filing operations such as writing text data and registering titles in an index are significantly simplified, and an excellent effect is achieved in that an electronic filing system with high operability is realized.
