2. Description of the Related Art In computer systems such as banks and securities, slips and forms are read by an image input device, and the read image data is read using automatic recognition software to check slip names, dates, customer names, deposit amounts, and the like. It converts customer transaction information into numerical information and inputs it to computer systems such as banks and securities companies. At this time, the character recognition rate by the automatic recognition software cannot always be read 100% correctly due to the influence of dirt on the input medium and unclear characters and numbers. Therefore, in order to finally confirm that the input data is correct, it is necessary for the operator to perform a confirmation operation. That is, a screen (hereinafter abbreviated as an OCR screen) displaying character information recognized by the automatic recognition software is compared with screen information of image data obtained by reading a slip or a form by an image input device, and each item is checked. Check whether the data is correctly recognized.
Normally, the financial terminal device that performs such a check displays one display screen separately on an upper screen and a lower screen. The operator performs a checking operation while comparing the two screens. At this time, by displaying a ruler or an image cursor on the display screen, the visibility of the transaction to be processed or the processing target item to be focused on is enhanced to enhance the recognition. Conventionally, a ruler or an image cursor itself is moved on a display screen by pressing a scroll key.

FIG. 4 shows an example of a display screen according to the prior art. In this example, a scroll operation of a ruler is illustrated. In the upper half of the display screen, an image screen for displaying image data is displayed, and in the lower half, two screens, an OCR screen displaying text data obtained by analyzing the image data, are displayed in a vertically divided manner. . The operator compares the contents on the upper and lower display screens while moving the ruler, and checks and confirms the contents. A ruler indicated by a bold line is displayed as an initial display screen substantially at the center of the upper half image screen (FIG. 4). In this state, when a scroll of ↓ (downward) is instructed from the input instructing means, the ruler itself moves line by line down the screen (FIGS. 4 and 4).

[0004]

Accordingly, the following problems have been encountered in controlling scrolling of image data. When the scroll key is pressed, the ruler or the image cursor itself moves on the image screen, so that the operator's field of view often moves, and it is difficult to collate and verify the display contents of the OCR screen with the display contents of the image data.

In the present invention, by pressing the scroll key,
By displaying a ruler or image cursor at a fixed position and scrolling image data, it is possible to reduce the movement of the operator's field of view during verification and verification work, enable smooth processing, and perform highly accurate confirmation. And

FIG. 1 is a block diagram of an embodiment of the present invention. The form a is recorded in the image buffer 10 as image data by the image input device 1. At this time, the image data is defined by the image input apparatus 1 or the system as a rectangular area having the origin at the upper left end and the vertical and horizontal lengths having R and D, respectively. The image data area setting means 21 of the image data display processing unit 20 uses the coordinates of the upper left corner of the image data as the image data area pointer IP (X,
Y) It is arranged on the image buffer 10 as 22. The window setting means 23 sets the position and size of the window area on the image buffer 10 as the display area pointer DP (X, Y) 24. The image data in this window area is displayed on the actual display screen on the display unit 50. Further, when the scroll key of the keyboard 2 is pressed, the scroll control means 12 recognizes the scrolling direction and determines whether the first boundary detection means 15 or the second boundary detection means 16 has detected the boundary. Then, a scroll instruction is issued to either the image data display processing unit 20 or the cursor display processing unit 30. That is, when the first boundary detection means 15 has not detected the boundary,
The position of the cursor to be displayed next is read out from the scroll pointer management table 14, and the window setting means 2 is read using the read value.
The display area pointer 24 set in step 3 is updated.
Thus, scrolling of image data is executed. When the first boundary detecting means 15 detects a boundary, the cursor setting means 31 of the cursor display processing unit 30 uses the ruler pointer 32 with the value of the position of the scheduled cursor read from the scroll pointer management table 14.
Alternatively, the image cursor pointer 33 is updated. By doing so, the scroll of the ruler or the image cursor is executed. The image data of the form a read by the image input device 1 is detected by the scroll pointer detecting means 13 for each X coordinate and Y coordinate, and is recorded in the scroll pointer management table 14. As described above, the entire scroll control function is performed by the control unit 11.
Do with.

FIG. 2 is a display principle diagram showing the correlation between the image buffer, the image data area, the window, and the display area pointer and the cursor pointer. This figure shows the following three points. 1) An image data area is set on the image buffer, and its position and size are indicated by an image data pointer IP.
It is arbitrarily specified by (X, Y). 2) Also, a window frame is set on the image buffer, and its position and size are indicated by the display area pointer DP (X,
Y) is arbitrarily specified. This window frame corresponds to the actual display screen, and the image data in the window frame is displayed on the screen. 3) Further, place a cursor in the window frame. Two examples of cursor display are a horizontal ruler and an image cursor indicating a rectangular area. These are set in the window frame, and the position is arbitrarily specified by the ruler pointer RP (-, y), and the position and size are arbitrarily specified by the image cursor pointer ICP (x, y).

The image data read from the image input device 1 is stored in the image buffer in a rectangular area with the vertical and horizontal lengths designated by R and D, with the image data pointer IP (X, Y) as the origin at the upper left corner. Will be recorded. For simplicity,
The origin of the upper left corner of the image data pointer IP (X, Y) may be made to coincide with the origin of the image buffer. That is, the outer frame of the image data area is the upper left end IP (X, Y)
Is the origin, and the lower left, upper right, and lower right are IP
(X, Y + R), IP (X + D, Y), IP (X + D,
(Y + R) is represented by a rectangular area surrounded by coordinate points.

On the other hand, a window indicating a display area on the image buffer 10 is displayed by a display pointer DP (X, Y).
The origin is set at the upper left corner of, and the vertical and horizontal lengths are indicated by a rectangular area specified by r and d. The lower left, upper right, and lower right corners are DP (X, Y + r), DP (X + d, Y), and DP (X
+ D, Y + r). The image data in this window area is displayed on the display screen. Here, the values of d and r can be arbitrarily set according to the performance of the display screen.

The scroll operation of the image data is shown in FIG.
In the direction specified by the cursor movement key on keyboard 2 shown in
Update the coordinate value of the display pointer DP (X, Y).
By doing For example, the image data
When moving, the amount of movement is determined by the value of Y. One
In other words, the currently displayed Y coordinate (Y_C) Against
Y coordinate after roll (Y_S) Difference (Y_S-Y_C) Is 40
Then, it is displayed at the coordinates shifted downward by 40 lines.
When moving image data to the right,
The moving amount is determined by the value of X. That is, currently displayed
X coordinate (X _C), The X coordinate after scrolling (X
_S) Difference (X_S-X_C) Is 80, 80 dots right
Display at coordinates shifted toward

Here, the coordinate value DP (X _S ,
Once Y _S ) is determined, the coordinate values of the other three points of the image data, which is a rectangular area, are DP (X _S , Y _S + r) and DP (X <sub>S
+ D, Y S), DP</sub> (X S + d, Y S + r) automatically determined and.

On the other hand, as shown in the lower part of FIG. 2, the display of the ruler and the image cursor is designated by the coordinate system of the window. For example, the ruler display position is a ruler pointer RP
By setting with (-, y) and updating the value of y, the horizontal line scrolls on the display screen. That is, for example, display the difference (y _S -y _C) coordinates shifted to 80 lines below if 80 coordinates that shows the current ruler (y _C) y-coordinate after scrolling respect (y _S) I do.

The display position of the image cursor is set by the image cursor pointer ICP (x, y). Similarly to the definition of the window area, the upper left corner of the ICP (x, y) is set as the origin, and the vertical and horizontal lengths are specified by a rectangular area specified by h and w. Lower left, upper right and lower right are IC
P (x, y + h), ICP (x + w, y), ICP (x
+ W, y + h). Here, w represents the length of the image cursor in the x direction, and h represents the length of the image cursor in the y direction.
3 or instructed by a higher-level program.

Here, in order to scroll the image cursor, the value of ICP (x, y) is changed according to the designated direction of the cursor moving key of the keyboard (2).
Update the value of y). For example, when a cursor movement is instructed downward, the movement amount is determined by the value of y. In other words, the difference between the y-coordinate (y _C) y-coordinate after scrolling with respect to the currently displayed _{(y S) (y S -y} C) is if 50 is displayed on a coordinate shifted to 50 lines below . When the cursor movement is instructed rightward, the movement amount is determined by the value of x. That is, the currently displayed x
If the coordinates difference (x _C) x-coordinate after scrolling relative _{(x S) (x S -x} C) is 80, and displays the coordinate shifted to 80 dots right. Thus, the display data created by the image data display processing unit 20 and the display data created by the cursor display processing unit 30 shown in FIG. 1 are combined and displayed on the display unit 50.

Here, the scroll operation of the ruler shown in FIG. 3 as the display screen of the present invention will be described. Here, only the image screen of the upper half image screen and the lower half text screen of the display screen described in the conventional example will be described. A ruler in the form of a horizontal line is displayed as an initial display screen substantially at the center of the image screen (FIG. 3). In this state, when a scroll of ↓ (downward) is instructed from the input instructing means, the scroll control means 12 in FIG. 1 recognizes that the key is in the downward direction, and the first boundary detecting means 1
5 has not detected a boundary, the current display pointer D
DP (X) in which only the Y coordinate of P (X _c , Y _c ) is set to Y _S
c, Y _S) and re-displayed as a new coordinates after scrolling the.
Then, the ruler is fixedly displayed on the display screen, and the image data scrolls one line upward in the screen (FIG. 3).

[0025] Here, if not over than the display pointer of the window bottom Y coordinate (Y _S + r) is an image data the lower end of the Y-coordinate (Y + R), again preset following new coordinate image data The display pointer is shifted to Y _S and displayed again (FIG. 3). At this time, since the Y coordinate of the pointer of the window bottom (Y _S + r) is the first boundary detection means 15 of FIG. 1 to be consistent with the lower end of the Y-coordinate of the image data (Y + R) is detected,
This completes the scroll operation of the image data.

[0026] The following scrolling operation rulers pointer RP that is currently displayed (-, y _C) new coordinates after scrolling the RP (-, y _S) redisplays go to (in Fig. 3). Here, since the second boundary detecting means 16 has detected that the Y coordinate of the ruler pointer coincides with the Y coordinate (Y + R) of the lower end of the image data, the scroll operation of the screen cursor key ends (FIG. 3).

The scroll operation of the ruler has been described above as an example, but the same applies to the case of an image cursor.
In the management table which manages the amount of scroll movement, a pointer is recorded by the scroll pointer detecting means 13 after a slip or a form is read from the image input device 1. Alternatively, the scroll pointer can be recorded as the coordinate value of the buffer by higher recognition software.

Next, the operation of the embodiment will be described with reference to a flowchart. FIG. 5 describes the operation of claim 1. Based on the instruction of the scroll direction from the input means [(a) of FIG. 5], the movement amount is obtained as the displacement amount from the cursor pointer currently displayed by the pointer management table and the cursor pointer after scrolling [FIG. (B)].

Next, a boundary flag is checked to determine whether the scroll target is image data or a cursor [(c) in FIG. 5]. When the boundary flag is '0', it indicates that the outer frame of the display area pointer does not reach the outer frame of the image data area, that is, it is within the image data area. The area pointer is updated ((d) in FIG. 5). Here, it is checked whether or not the value of the outer frame of the newly set display area pointer has reached the value of the outer frame of the image data area [(e) in FIG. 5]. When the value of the outer frame of the display area pointer has reached the value of the outer frame of the image data area, the boundary flag is set to "1" (FIG. 5 (f)).

Next, when the window display is executed with the new display area pointer, the image data is scrolled and displayed [(g) in FIG. 5]. When the boundary flag is "1" in (c), it indicates that the outer frame of the display area pointer has reached the outer frame of the image data area, and thus the scroll operation of the cursor pointer is executed. First, confirm that the stop flag is "0" ((h) in FIG. 5),
The cursor pointer is updated using the displacement amount ((i) in FIG. 5).

Next, it is checked whether or not the value of the outer frame of the newly set cursor pointer has reached the value of the outer frame of the image data area [(nu) in FIG. 5]. When the value of the outer frame of the cursor pointer has reached the value of the outer frame of the image data area, the stop flag is set to "1" (FIG. 5 (l)).

Next, the currently displayed cursor is erased ((ヲ) in FIG. 5), and when the window is displayed with the new cursor pointer, the cursor is scrolled and displayed [(W) in FIG. 5]. .

FIG. 6 shows the operation of claim 2. (I),
(B) is the same as FIG. First, the cursor pointer is updated using the displacement amount obtained in the same manner as in FIG. 5 ((c) in FIG. 6).

Next, it is checked whether or not the value of the outer frame of the newly set cursor pointer has reached the value of the outer frame of the image data area ((d) in FIG. 6). When the value of the outer frame of the cursor pointer does not reach the value of the outer frame of the image data area, it indicates that the cursor pointer is within the image data area. Update [(e) in FIG. 6].

Next, when the window display is executed with the new display area pointer, the image data is scrolled and displayed [FIG. 6 (f)]. When the boundary is detected in (d), the flow ends.

[0036]

As described above, according to the present invention, since the ruler or the image cursor is fixedly displayed and the image data is moved, the movement of the operator's line of sight can be eliminated, and the effect of preventing fatigue can be obtained. Accurate recognition becomes possible. Further, full display of the image data on the display screen becomes possible, and the visibility in operation can be improved.
