Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data part acquisition display device.

[0002]

2. Description of the Related Art With the spread of optical character readers (hereinafter abbreviated as OCR), business processing for reading data by OCR is increasing. Since the writer may make an entry that extends beyond the reading field frame on the form or makes an entry outside the reading field, it may not be recognized by the OCR. In this case, the operator displays the entire image of the form in order to correct the input, corrects the input from the image display, and inputs the correction.

However, since there is a problem of space on the screen, only the entire image of the form is displayed, and detailed display such as enlarging and displaying an unreadable part cannot be performed. The recognition rate from the image data read from the OCR has a low recognition rate, and it is necessary to add a portion that cannot be read by the OCR and correct a portion that is erroneously read by interposing an operator input for each form.

FIG. 9 is a block diagram of a conventional display device. In the figure, 2 is an OCR, which is a reading unit 3, a recognition unit 4,
The storage unit 8 and the control unit 7 are provided. Reference numeral 1 is a slip, which is an object read by the OCR 2. A reading unit 3 photoelectrically converts the voucher 1 which is a reading object into read image data 5 and stores the read image data 5 in the storage unit 8. A recognition unit 4 recognizes the image data 5 of the slip 1 stored in the storage unit 8 and converts it into character data 6. Image data 5 is output from the reading unit 3. Character data 6 is output from the recognition unit 4. 7 is a control unit, which is an OC
It controls R2. A storage unit 8 stores data such as image data 5 character data 6 and the like.

Reference numeral 9 is display software, which is a control unit 7.
Controls the OCR2 according to the display software 9. A screen buffer 10 stores data to be displayed on the display unit 11. A display unit 11 displays the contents of the screen buffer 10. An input unit 12 is used by the operator 13 to input data to the OCR2. An operator 13 uses the OCR2.

FIG. 10 is a control flowchart of a conventional OCR. The operation of OCR will be described with reference to the drawings. In step 80, the OCR 2 first reads the slip 1 by photoelectrically converting it in the reading unit 3, converts it into image data 5, outputs it, and stores it in the storage unit 8.

The image data 5 stored in the storage unit 8 in step 81 is input to the recognition unit 4, and the recognition unit 4 recognizes the image data 5 and converts it into character data 6. At this time, the part where the character cannot be recognized is output with a specially defined code.

In step 82, the character data 6 and the image data 5 as a result of recognition by the OCR 2 are stored in the screen buffer 10 and displayed on the display unit 11. Step 83
Then, if it is necessary to make corrections or additions to the displayed character data while looking at the image data 5, the process proceeds to step 84, and if not necessary, the process ends.

When making corrections or additions to the character data in step 84, the operator moves the cursor to the item. In step 85, the operator 13 inputs corrections and additions.

Then, returning to step 83, the operator 13 checks whether another correction or addition is necessary. Where step 83
The operator compares the image data displayed on the screen with the character data and inputs the correct information.
For item 13, when the displayed image data is difficult to read and difficult to recognize, the original slip 1 was checked and input was made.

In this way, when inputting a slip from an OCR at a financial institution or the like, a person always visually confirms the input data of the account number and the amount of money, and if necessary, makes a correction and additional input.

[0012]

Therefore, when the operator inputs corrections or additions while viewing the entire image display of the slip, it is necessary to check the original slip for the display data that is difficult to confirm. There was a problem that the input efficiency was lowered. The present invention has been made in view of the above points, and an object thereof is to provide a means for improving the visibility of an operator and the efficiency of operator input by processing an image display.

[0013]

The above-mentioned problems can be solved by an image data part acquisition display device constructed as follows.

FIG. 1 shows the principle of the present invention. In an optical character reader for recognizing characters written in a predetermined column by reading a form, input field identification information 21 for associating the position where the cursor 16 is displayed with the input field 15 defined in the form, and the cursor 16 The input field 15 to which the displayed position belongs
Cursor position identification means 22 identified by 21, image position information 23 defining position information of image data corresponding to the input field 15, and image data for acquiring image data of an area specified by the image position information 23 An acquisition unit 24, a field definition unit 25 defining image definition information of the acquired image data display attribute, and an image data display unit 26 for displaying the acquired image data on a screen according to the image definition information. To configure.

[0015]

The input field identification information 21 stores data associating the position where the cursor 16 is displayed with the input field 15 defined in the form.

The cursor position identification means 22 reads the displayed position of the cursor 16 and identifies the input field 15 to which the position belongs by the input field identification information 21.
The image position information 23 stores data associating the position information of the image data corresponding to the input field 15. The image data acquisition means 24 acquires the partial image data of the area designated by the image position information 23.

The image data display means 26 displays the acquired partial image data according to the image definition information of the field definition section 25 which defines the image definition information of the acquired image data display attribute.

Therefore, the image data corresponding to the input field in which the cursor exists can be processed and displayed so that it can be easily identified by the operator, and the visibility of the operator and the efficiency of operator input can be improved. ..

FIG. 4 is a control flowchart of the embodiment of the present invention, which shows the control operation of the image part acquisition display device of the embodiment of the present invention. Further, FIG. 5 is a detailed flowchart of the image part acquisition unit of the embodiment of the present invention, and corresponds to steps 31, 32 and 33 of FIG. The operation of the embodiment of the present invention will be described below with reference to the drawings.

Since steps 80 to 84 are the same as the conventional operation, the description thereof will be omitted. In step 86, the screen display is redisplayed. This is to display the image data again in order to return to the initial image display because the display of the image display area is changed by the image part acquisition unit 27.

The operation of the image part acquisition unit 27 will be described with reference to FIG. In step 87, the position (X, Y) at which the cursor exists is read in order to check whether or not the operator 13 has moved the cursor to the input field for additional correction input. In step 88, since the input field area and the input field name are stored in the input field identification information 21 in association with each other, the areas (X _C1 , Y _C1 , X _C2 , Y _C2 ) are sequentially taken out.
The area is a rectangle defined by upper left coordinates and lower right coordinates.

If it is judged at step 89 whether or not the cursor position (X, Y) is in the area (X _C1 , Y _C1 , X _C2 , Y _C2 ), the routine goes to step 90, otherwise to step 91. move on. In step 90, the input field name of the corresponding area is stored and the process proceeds to step 93. In step 91, it is checked whether or not the input field identification information 21 has an area for the next input field.
Return to 83.

In step 92, the area of the next input field is extracted and the process returns to step 89. In this way, it is possible to find out which input field the cursor position belongs to. In step 93, the image position information corresponding to the stored input field name is obtained from the image position information 23.

Image position information (X
Image data 5 that is the image data of the slip 1 with the area specified by _i1 , Y _i1 , X _i2 , Y _i2 ) (also the rectangular area defined by the upper left coordinates and the lower right coordinates in this case) as partial image data. Take out from.

In step 95, the field definition section 25 obtains image definition information corresponding to the input field name. Step
The partial image data extracted in 96 is processed and displayed based on the obtained image definition information.

This completes the operation of the image part acquisition section. The image display which has been processed and made easier to see makes it easier for the operator to read the image data and make correction and additional input.

After step 96, returning to FIG. 4, step 85
Then, the operator inputs correction and addition, and the character data is corrected and the display content is corrected by this work, and the process returns to step 83. If there is an item to be further input in step 83, the process proceeds to step 84 and the cursor is moved. So step 86
To redisplay the display and notify the operator 13 of the movement of the input field. FIGS. 6, 7, and 8 are examples (1), (2), and (3) of screen display according to the embodiment of the present invention, showing the operation of the cursor and the display of image data in the present invention. It was done. (A) in the figure is an initial display example, and the cursor is set at the position of the first character of the account number which is the first input field. Then, only the partial image data 18 corresponding to the account number, which is the input field to which the cursor belongs, is displayed with the display color changed. In addition, "177? 7" is displayed in the amount column indicating that "17777" of the image data is O.
It was displayed as "?" Because the fourth character could not be read when reading with CR. (B) in the figure shows the case where the account number portion corresponding to the partial image data 18 is displayed as blank because it could not be read by OCR, and the operator reads the image display and inputs "12345" in the input field. FIG. 7C is a diagram showing a display when the cursor is moved to the input field of the bank name kana, and is a diagram showing that the display area of the partial image data is moved in association with the cursor. .. At this time, the partial image data 18 becomes a part displayed as "Gunma", and the color is changed and displayed.

In FIG. 7D, two display locations of the partial image data are defined, and one location is displayed as the partial image data 18 with the attribute changed at the same location as the acquisition location,
In the other part 19, the image data of the same part is enlarged and displayed,
It is an example when it is displayed on the input field item. Such a display has an advantage in that it is possible to display only a detailed image of a necessary portion and to read characters that are difficult to read.

When there is no suitable place to display, the area for which input has been completed is used as the display area. In this case, since the input of the bank name kana has been completed, it is temporarily used as an image display area.

The display image data "17" is also shown in FIG.
777 ”is defined as two display locations, one location is a display where the attribute is changed at the same location as the acquisition location (for example, changing the color, reverse, etc.), and the other location is for the acquired image data. If the recognition unit searches for the existence of unrecognizable image data, if it exists, the field definition is performed according to the image data, the partial image data 18b is acquired, the attribute is changed, and the partial image data 18a, It is a display example when displayed as 18b and 18c.

Since the partial image data 18b could not be read by the OCR, the display color is changed only for that portion, and the remaining image data 18a and 18c are combined and displayed in the original color. In this case, there is an effect that it is possible to immediately recognize where the unreadable part is the part displayed with "?". FIG. 8F shows a display example when the acquired partial image data 18 is enlarged and displayed at the same place as the acquisition place.

[0039]

As described above, according to the present invention,
By acquiring the partial image data corresponding to the item to be input from the whole image data, processing it, and displaying it,
It is possible to improve the visibility of the operator, which greatly contributes to the efficiency of operator input.
