2. Description of the Related Art In recent years, business forms using OCR devices have been increasing in many industries including banks, and there are many opportunities to input data while viewing image data of a read form.

However, the size of the read form and the position and arrangement of the data written on the form vary from company to company and vary widely.

In particular, as a currency exchange slip used in banking business, a user often uses a slip written in an arbitrary size and an arbitrary format, and when this is read, the screen size is determined. The scanned form was displayed in a reduced size, but the reduced size made it difficult to see the screen.

There is also a method of displaying image data without reducing the size and inputting while scrolling. In this method, however, the image data corresponding to the input item must be searched for and scrolled, so the key operation is complicated. There was a problem that became.

[0006] Therefore, from the viewpoint of improving the efficiency of work and improving the operability, there is a demand for a method in which the screen is easy to see and the number of key operations is minimum.

FIG. 10 is a block diagram showing a conventional input control device using such a scroll method.

In the figure, 51 is an OCR device for reading the image data, 52 is an image data display screen section for displaying the read image data, and 53 is for inputting each item when the image data is requested. An input control unit 54 for input control is an image data scroll unit 54 for scrolling image data when the operator presses a scroll key.

In such a structure, first, the OCR device 5
The image data read by 1 is displayed on the image data display screen section 52.

Next, when the operator makes an input request, the input control section 53 makes an input for each item. further,
When the operator wants to see a specific portion of the input image data, he or she depresses a scroll key to scroll the image data so that a desired specific portion of the image data can be seen.

11 and 12 are diagrams conceptually showing the operation of the conventional method. In the figure, the handwritten form B5 is read by the OCR device, the read handwritten characters are displayed as shown in the image data display screen 98 in the upper column of the display screen 6 (see FIG. 11), and the manual input screen in the lower column is displayed. Account No. 99 The fields for entering the bank name, branch name, name, etc. are displayed.

Next, the operator selects the account number. When the bank name, branch name, and name are entered, they are displayed on the manual input screen 99 of the display screen 7 of FIG.

When the operator presses the scroll key, the image screen scrolls as shown in the image data display screen 98 of the display screen 8, the address and telephone fields are displayed on the image data display screen 98, and the next item is displayed. Be prepared for easy entry.

The image data scroll section 17 scrolls the screen by a predetermined number of line columns.

Next, an outline of the operation in this configuration will be described with reference to a conceptual diagram.

3 and 4 are operation explanatory views for conceptually explaining the operation of the embodiment of the present invention, FIG. 5 is an explanatory view showing an embodiment of the screen definition body, and FIG. 6 is for explaining the character recognition operation. FIG.

In this embodiment, as shown in the operation conceptual diagrams of FIGS. 3 and 4, the handwritten form A21 as image data is read by the OCR device and displayed on the image data display screen 98 of the image data screen display unit 11. Is displayed.

In this case, the display screen is displayed as shown by the screen 22 in FIG. On the image data display screen 98 of the display screen 22, handwritten accounts, banks and branches of the handwritten form A21 are read and displayed.

Here, the operator, while viewing the image data displayed on the image data display screen 98, manually inputs in the corresponding column of the manual input screen 99 in the lower column of the screen.

FIG. 5 shows an embodiment of the form of the screen definition body. In the figure, 31 is the total number of items of image data, 32 is the related image data offset of each item, which is composed of, for example, an account, a bank, a branch or the like. Three
No. 3 of each item. , 34 indicates the data of each item, 35 indicates the row position of each item, and 36 indicates the column position of each item.

That is, if the related image data offset of the item of the screen definition shown in FIG. 5 is entered, for example, in the corresponding column of account, bank or branch of 32 of FIG. 5, the manual input screen of the display screen 23 of FIG. As shown in FIG. Manually enter "0123456", the bank name is "Daiichi Kangyo", and the branch name is "Maebashi Ekimae".

Further, when the name is input, the name "Shigeki Ozawa" is input and the image data display screen 98 is scrolled as shown in the manual input screen 99 of the display screen 24 of FIG.

As described above, the screen scrolling is performed when the image data corresponding to the item currently being input (the item where the cursor is displayed) is not displayed.

The case of FIG. 4 is the same as the case of FIG. 3 except that the form format is different. That is, the handwritten form B25 is read by the OCR device and displayed on the image data display screen 98.

This display screen is displayed on the image data display screen 98 as shown in the display screen 26 of FIG. 4. The handwritten account "0123456", the bank name "1st business", the name "Koju", and the branch name "Maebashi station square" Is displayed.

Here, as in the case of FIG. 3, the account N of the related image data offset of the item of the screen definition body of FIG.
o. Input screen, bank, branch, name and display screen 2 in Fig. 4
The image data display screen 98 scrolls as in 7, and the address column is displayed.

FIG. 6 is a diagram for explaining a character recognition state in which image data is recognized for each data block. In the figure, the data block 42 of the image "bank" shown as the image data bitmap 41 is recognized by the character recognition mechanism 43 as the recognized character "bank".

FIG. 7 is a flow chart for explaining the operation of the embodiment of the present invention. The operation of the present invention will be described below with reference to the flowchart of FIG.

First, the operator inputs the input items defined by the definition structure shown in FIG. 5 to the input control unit 12 (step S1).

At this time, the processing is ended when the input of all the items is completed or the forced termination of the operation is instructed by an end key or the like from an input device (not shown).

On the other hand, when the input of all items is not completed, the input control unit 12 gives an instruction to the cursor display unit 13 to start the column position of the input item, that is, 35 in FIG.
The cursor is displayed at the position indicated by 36 (step S
2).

Then, the corresponding data of the input item in step S1, that is, the data for one item shown in 32 to 36 in FIG. 5 is acquired and stored in a memory not shown (step S).
3).

The data corresponding to this input item is acquired from the line position of the cursor currently displayed by the number 3 indicated by 32 in FIG.
Based on the information of 4 to 36, which item is currently input target is searched, and the data of the target item (32 to 3
6) is acquired.

Further, 32 pieces of information (used at the time of data block search) are acquired from the acquired information (32 to 36), and based on this information, it is determined whether or not the same character exists in the form. The data block of the read image data is searched (step S4).

When the search for the data block for one character is completed, it is checked whether or not the next data block exists (step S5). That is, the image data recognizing unit 15 determines whether or not the data block searched in step S4 exists. If it does not exist, the process branches to step S12, and if it exists, the process proceeds to step S6.

Next, if there is a data block, the image data recognition unit 15 performs character recognition for each of the image data blocks 42 (step S).
6).

Then, the correspondence data determination unit 14 checks whether the image data recognized in step S6 is the same as the correspondence data in step S3. If they are the same, step S8 is executed.
If it is different, the process returns to step S4 and the data block is searched again (step S7).

When the recognized image data is determined to be the same in step S7, the line digit position of the image data is acquired (step S8).

There are several methods for acquiring the row digit position of this image data. For example, the fixed row digit position acquisition method shown in FIG. 8 is a method of defining how many bits of image data are to be one row and one digit.
This is a method of calculating the row digit from the bit position of the data block.

The method of variably acquiring the line digit position by the character illustrated in FIG. 9 is a method of determining the bit of the line digit on the basis of the size of the character (data block) at the time of reading the image data, There is also a method of determining the line column size based on the size of the written character.

There are various methods for acquiring the row and column position in addition to the above-exemplified method, and any of them can be used.

Then, it is checked whether or not the line digit detected in step S8 exists in the displayed image data (step S9). If it is determined that the target image data is within the currently displayed screen, step S12
Proceed to.

On the other hand, when the target image data is not in the screen being displayed, for example, the line digit detected in step S8 is the 9th line and the 10th column, and the item data length of the definition target input item is 20 digits. Then, the displayed image data is 3
If the number of lines to 8 to 5 digits to 30 digits is reached, it is determined that the target image data does not exist in the displayed screen, and the process branches to step S10.

Then, the scroll amount determination unit 16 calculates the scroll amount of the image data (step S1).
0). For example, the line digit position detected in step S8 is the 9th line and the 10th column, and the item data length of the input object of the definition is 2
If it is 0 digit, the displayed image data is 3 to 8 lines, 5
It can be seen that when the number of digits is up to 30 digits, the screen is displayed by scrolling the row digit position by one line. Therefore, the calculation result is that one line is scrolled.

Next, image data scroll processing is performed (step S11). That is, the image data scroll unit 17 performs a process of scrolling the image data (image screen).

Then, it is determined whether or not the cursor is inside the input item (step S12), and if it is outside the input item, it is determined that the input of the item is completed, and the process is moved to step S1.

On the other hand, when the cursor is in the input item, the input information is acquired (step S13). That is,
This is a process of acquiring input information from an input device such as a keyboard.

Then, the cursor is moved (step S14). That is, after the input information is acquired, the process of moving the cursor by the number of digits of the acquired input information is performed.

In this way, the screen corresponding to the input target item is always displayed on the image data display screen 98, and the cursor is moved to the input target item.

[0070]

As described above, according to the present invention,
When an operator inputs data while looking at the image data read from the OCR device, the data of the input target item is automatically displayed on the screen without the operator's scroll key operation, so input without wasted key operation It is possible to improve efficiency.
